Business Segments
Consumers Electric Utility
Electric Utility Operations: Consumers’ electric utility operations, which include the generation, purchase, transmission, distribution, and sale of electricity, generated operating revenue of $4.4$5.0 billion in 2019, $4.6 billion in 2018,2021, and $4.4 billion in 2017.2020 and 2019. Consumers’ electric utility customer base consists of a mix of primarily residential, commercial, and diversified industrial customers in Michigan’s Lower Peninsula.

Presented in the following illustration is Consumers’ 20192021 electric utility operating revenue of $4.4$5.0 billion by customer class:
chart-ceelectricutiloperrev.jpgcms-20211231_g2.jpg
Consumers’ electric utility operations are not dependent on a single customer, or even a few customers, and the loss of any one or even a few of Consumers’ largest customers is not reasonably likely to have a material adverse effect on Consumers’ financial condition.
In 2019,2021, Consumers’ electric deliveries were 3736 billion kWh, which included ROA deliveries of fourthree billion kWh, resulting in net bundled sales of 33 billion kWh. In 2018,2020, Consumers’ electric deliveries were 3835 billion kWh, which included ROA deliveries of fourthree billion kWh, resulting in net bundled sales of 3432 billion kWh.
Consumers’ electric utility operations are seasonal. The consumption of electric energy typically increases in the summer months, due primarily to the use of air conditioners and other cooling equipment.

Presented in the following illustration are Consumers’ monthly weather-normalized electric deliveries (deliveries adjusted to reflect normal weather conditions) to its customers, including ROA deliveries, during 20192021 and 2018:2020:
chart-ceweathnormelectricdel.jpgcms-20211231_g3.jpg
Consumers’ 20192021 summer peak demand was 8,0397,951 MW, which included ROA demand of 562581 MW. For the 2018-20192020-2021 winter season, Consumers’ peak demand was 5,7455,386 MW, which included ROA demand of 440465 MW. As required by MISO reserve margin requirements, Consumers owns or controls, through long-term PPAs and short-term capacity purchases, all of the capacity required to supply its projected firm peak load and necessary reserve margin for summer 2020.2022.
Electric Utility Properties: Consumers owns and operates electric generation transmission, and distribution facilities. For details about Consumers’ electric generation facilities, see the Electric Utility Generation and Supply Mix section that follows this Electric Utility Properties section. Consumers’ transmission and distribution systems consistsystem consists of:
213 miles of transmission overhead lines operating at 138 kV
205208 miles of high-voltage distribution overhead lines operating at 138 kV
4 miles of high-voltage distribution underground lines operating at 138 kV
4,4304,428 miles of high-voltage distribution overhead lines operating at 46 kV and 69 kV
19 miles of high-voltage distribution underground lines operating at 46 kV
66,91782,474 miles of electric distribution overhead lines
9,3149,395 miles of underground distribution lines
1,093 substations with an aggregate transformer capacity of 26 million kVA
twothree battery facilities with storage capacity of 2 MWMWh
Consumers is interconnected to the interstate high-voltage electric transmission system owned by METC and operated by MISO. Consumers is also interconnected to neighboring utilities and to other transmission systems.


17



Electric Utility Generation and Supply Mix: During 2020, Consumers announced a goal of achieving net-zero carbon emissions from its electric business by 2040. This goal includes not only emissions from
18

Consumers’ owned generation, but also emissions from the generation of power purchased through long-term PPAs and from the MISO energy market.
Consumers expects to meet 90 percent of its customers’ needs with clean energy sources by 2040 through execution of its 2021 IRP, which calls for replacing its coal-fueled generation predominantly with investment in renewable energy. Carbon offset measures including, but not limited to, carbon sequestration, methane emission capture, and forest preservation and reforestation may be used to close the gap to achieving net-zero carbon emissions. Specifically, the 2021 IRP provides for a full transition away from coal-fueled generation by the end of 2025 and includes the retirement of the D.E. Karn oil/gas-fueled and coal-fueled generating units in 2023 and the J.H. Campbell coal-fueled generating units in 2025. For further information on Consumers’ progress towards its net-zero carbon emissions goal, see Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Executive Overview.

Represents purchases from the MISO energy market.
During 2019,2021, Consumers acquired 5247 percent of the electricity it provided to customers through long-term PPAs and the MISO energy market. Consumers offers its generation into the MISO energy market on a day-ahead and real-time basis and bids for power in the market to serve the demand of its customers. Consumers is a net purchaser of power and supplements its generation capability with purchases from the MISO energy market to meet its customers’ needs during peak demandpeak-demand periods.
At December 31, 2019,2021, Consumers had future commitments to purchase capacity and energy under long-term PPAs with various generating plants. These contracts require monthly capacity payments based on the plants’ availability or deliverability. The payments for 20202022 through 20402048 are estimated to total $9.4$8.0 billion and, for each of the next five years, range from $0.6 billion to $1.1$0.8 billion annually. These amounts may vary depending on plant availability and fuel costs. For further information about Consumers’ future capacity and energy purchase obligations, see Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Capital Resources and Liquidity—Contractual ObligationsOther Material Cash Requirements and Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 4,3, Contingencies and Commitments—Contractual Commitments.
During 2019, 272021, 32 percent of the energy Consumers provided to customers was generated by its coal-fueled generating units, which burned six million tons of coal and produced a combined total of 9,77610,861 GWh of electricity. In order to obtain the coal it needs, Consumers enters into physical coal supply contracts.

At December 31, 2019,2021, Consumers had future commitments to purchase coal through 2021;2023; payment obligations under these contracts totaled $84$116 million. Most of Consumers’ rail-supplied coal contracts have fixed prices, although some contain market-based pricing. Consumers’ vessel-supplied coal contracts have fixed base prices that are adjusted monthly to reflect changes to the fuel cost of vessel transportation. At December 31, 2019,2021, Consumers had 7795 percent of its 20202022 expected coal requirements under contract, as well as a 44-day23-day supply of coal on hand.
In conjunction with its coal supply contracts, Consumers leases a fleet of railcars and has transportation contracts with various companies to provide rail and vessel services for delivery of purchased coal to Consumers’ generating facilities. Consumers’ coal transportation contracts are future commitments and expire on various dates through 2024;2025; payment obligations under these contracts totaled $732$533 million at December 31, 2019.2021.
During 2019, 182021, 16 percent of the energy Consumers provided to customers was generated by its natural gas‑fueled generating units, which burned 4540 bcf of natural gas and produced a combined total of 6,2895,555 GWh of electricity.
In order to obtain the gas it needs for electric generation fuel, Consumers’ electric utility purchases gas from the market near the time of consumption, at prices that allow it to compete in the electric wholesale market. For units 3 & 4 of D.E. Karn and for the Jackson and Zeeland plants, Consumers utilizes an agent that owns firm transportation rights to each plant to purchase gas from the market and transport the gas to the facilities.
Electric Utility Competition: Consumers’ electric utility business is subject to actual and potential competition from many sources, in both the wholesale and retail markets, as well as in electric generation, electric delivery, and retail services.
Michigan law allows electric customers in Consumers’ service territory to buy electric generation service from alternative electric suppliers in an aggregate amount capped at ten percent of Consumers’ sales, with certain exceptions. At December 31, 2019,2021, electric deliveries under the ROA program were at the ten‑percent limit. Of Consumers’ 1.81.9 million electric customers, 285 customers,fewer than 300, or 0.02 percent, purchased electric generation service under the ROA program. For additional information, see Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Outlook—Consumers Electric Utility Outlook and Uncertainties.
Consumers also faces competition or potential competition associated with industrial customers relocating all or a portion of their production capacity outside of Consumers’ service territory for economic reasons; municipalities owning or operating competing electric delivery systems; and customer self-generation. Consumers addresses this competition in various ways, including:
aggressively controlling operating, maintenance, and fuel costs and passing savings on to customers
providing renewable energy options and energy waste reduction programs
providing competitive rate-design options, particularly for large energy-intensive customers
offering tariff-based incentives that support economic development
providing non‑energy services and value to customers
monitoring activity in adjacent geographical areas

Consumers Gas Utility
Gas Utility Operations: Consumers’ gas utility operations, which include the purchase, transmission, storage, distribution, and sale of natural gas, generated operating revenue of $2.1 billion in 2021, $1.8 billion in 2020, and $1.9 billion in 2019, $1.9 billion in 2018, and $1.8 billion in 2017.2019. Consumers’ gas utility customer base consists of a mix of primarily residential, commercial, and diversified industrial customers in Michigan’s Lower Peninsula.
Presented in the following illustration is Consumers’ 20192021 gas utility operating revenue of $1.9$2.1 billion by customer class:
chart-cegasutiloperrev.jpgcms-20211231_g4.jpg
Consumers’ gas utility operations are not dependent on a single customer, or even a few customers, and the loss of any one or even a few of Consumers’ largest customers is not reasonably likely to have a material adverse effect on Consumers’ financial condition.
In 2019,2021, deliveries of natural gas through Consumers’ pipeline and distribution network, including off-system transportation deliveries, totaled 391347 bcf, which included GCC deliveries of 4133 bcf. In 2018,2020, deliveries of natural gas through Consumers’ pipeline and distribution network, including off-system transportation deliveries, totaled 386360 bcf, which included GCC deliveries of 4436 bcf. Consumers’ gas utility operations are seasonal. The consumption of natural gas typically increases in the winter, due primarily to colder temperatures and the resulting use of natural gas as heating fuel. Consumers injects natural gas into storage during the summer months for use during the winter months. During 2019, 402021, 46 percent of the natural gas supplied to all customers during the winter months was supplied from storage.

chart-ceweathnormgasdeliv.jpgcms-20211231_g5.jpg
Gas Utility Properties: Consumers’ gas transmission, storage, and distribution system consists of:
2,4262,392 miles of transmission lines
15 gas storage fields with a total storage capacity of 309 bcf and a working gas volume of 151 bcf
27,72928,065 miles of distribution mains
eight compressor stations with a total of 163,543149,817 installed and available horsepower

In 2019, Consumers released its Methane Reduction Plan, which set a goal of net-zero methane emissions from its natural gas delivery system by 2030. Consumers plans to reduce methane emissions from its system by about 80 percent by accelerating the replacement of aging pipe, rehabilitating or retiring outdated infrastructure, and adopting new technologies and practices. The remaining emissions will be offset by purchasing and/or producing renewable natural gas. For further information on Consumers’ progress towards its net-zero methane emissions goal, see Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Executive Overview.

Gas Utility Supply: In 2019,2021, Consumers purchased 8384 percent of the gas it delivered from U.S. suppliers. The remaining 1716 percent was purchased from authorized GCC suppliers and delivered by Consumers to customers in the GCC program. Presented in the following illustration are the supply arrangements for the gas Consumers delivered to GCC and GCR customers during 2019:2021:
chart-cegasutilsupplagreemts.jpgcms-20211231_g6.jpg
Firm gas transportation or firm city-gate contracts are those that define a fixed amount, price, and delivery time frame. Consumers’ firm gas transportation contracts are with Panhandle Eastern Pipe Line Company and Trunkline Gas Company, LLC, each a non‑affiliated company. Under these contracts, Consumers purchases and transports gas to Michigan for ultimate delivery to its customers. Consumers’ firm gas transportation contracts expire on various dates through 2023 and provide for the delivery of 3937 percent of Consumers’ total gas supply requirements in 2020.2022. Consumers purchases the balance of its required gas supply under firm city-gate contracts and through authorized suppliers under the GCC program.
Gas Utility Competition: Competition exists in various aspects of Consumers’ gas utility business. Competition comes from GCC and transportation programs; system bypass opportunities for new and existing customers; and from alternative fuels and energy sources, such as propane, oil, and electricity.

CMS Energy and Consumers Environmental Strategy and Compliance
CMS Energy and Consumers are committed to protecting the environment; this commitment extends beyond compliance with applicable laws and regulations. CMS EnergyIn 2020, Consumers announced a goal of achieving net-zero carbon emissions from its electric business by 2040. This goal includes not only emissions from Consumers’ owned generation, but also emissions from the generation of power purchased through long-term PPAs and Consumers continue to focus on opportunities to reduce their carbon footprint in electric generation. Through its Clean Energy Plan, from the MISO energy market.
Consumers expects to reduce carbon emissionsmeet 90 percent of its owned generation by more than 90 percent from its 2005 levelscustomers’ needs with clean energy sources by 2040 bythrough execution of its 2021 IRP, which calls for replacing its coal-fueled generation predominantly with investment in renewable energy. Carbon offset measures including, but not limited to, carbon sequestration, methane emission capture, and forest preservation and reforestation may be used to close the gap to achieving net-zero carbon emissions.
During 2019,2021, Consumers provided 1013 percent of its electricity (self-generated and purchased) from renewable sources. In February 2021, Consumers ownstook ownership and operates two wind farms: Lake Winds® Energy Park and Cross Winds® Energy Park. A third phase of Consumers’ Cross Winds® Energy Park, with nameplate capacity of 76 MW, began operations in December 2019. During 2019, Consumers began constructionoperation of a 150-MW166-MW wind generation project andin Hillsdale, Michigan. Additionally, during 2021, Consumers entered into an agreementagreements to purchase another with capacity uptwo solar generating facilities as well as PPAs to 166 MW; both projectspurchase renewable energy from solar generating facilities presently being developed by other parties. For additional information on these facilities, which are expected to be operational between 2022 and 2024, see Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Outlook—Consumers Electric Utility Outlook and Uncertainties.
In addition to Consumers’ efforts to reduce the electric utility’s carbon footprint, it is also making efforts to reduce the gas utility’s methane footprint. In 2019, Consumers released its Methane Reduction Plan, which set a goal of net-zero methane emissions from its natural gas delivery system by 2030. Consumers plans to reduce methane emissions from its system by about 80 percent by accelerating the replacement of aging pipe, rehabilitating or retiring outdated infrastructure, and adopting new technologies and practices. The remaining emissions will be offset by purchasing and/or producing renewable natural gas.
In December 2021, Consumers announced plans to begin commercial operations in 2020. Additionally, Consumers entereddevelopment of a renewable natural gas facility that will capture methane from manure generated at a neighboring farm and convert it into a 20‑year agreement to purchase 100 MW of renewable energy from a solar generatingnatural gas. The facility, expected to begin operationsstart production in 2021.2023, will reduce methane emissions from the dairy farm and allow Consumers to deliver renewable natural gas as a cost-effective clean alternative fuel for customers.

compensation and benefits that are competitive with industry peers. Furthermore, CMS Energy and Consumers have developed a comprehensive talent strategy, the Talent Roadmap, to attract, develop, and retain highly skilled employees. The strategy focuses on three areas, which are summarized below.
Cultivating a Purpose-Driven Culture: This goal is aimed at ensuring all co-workers understand how their work drives CMS Energy’s and Consumers’ key strategic goals. CMS Energy’s and Consumers’ progress toward a purpose-driven culture is measured through an engagement index and an empowerment index developed from data obtained through an annual employee engagement survey of union and non-union co-workers administered by a third party. For the year ended December 31, 2021, the employee engagement index score was 81 percent, which ranked in the first quartile of U.S. utilities. The employee empowerment index score, which measures the percentage of employees that feel the workplace promotes empowerment, was 63 percent. Each employee empowerment question was individually benchmarked and ranked in the third quartile of general industry companies. The general industry benchmark was created by the third party who administered the survey through a targeted sampling of working adults within the U.S. who work for firms with widely respected reputations. CMS Energy and Consumers have a goal to achieve a first-quartile empowerment index score by 2026.
Creating a Breakthrough Employee Experience: A breakthrough employee experience is one that instills pride and ownership in one’s work. To measure progress toward a breakthrough employee experience, CMS Energy and Consumers measure employees’ satisfaction with people processes, such as performance management and hiring and onboarding new employees. For the year ended December 31, 2021, the employee experience index was 77 percent; CMS Energy and Consumers have a goal to achieve a score of 80 percent by 2030.
Building Skill Sets at Scale: With an overarching goal of ensuring employees have the right skills to succeed, CMS Energy and Consumers measure progress in this area through achievement of workforce planning and hiring milestones and through a first-time skill attainment index to evaluate the effectiveness of training. CMS Energy and Consumers develop skill sets in co-workers through a variety of means, including union apprenticeship programs and yearly trainings for newly required skills. In 2021, CMS Energy and Consumers launched a full-scale development program for leaders to enable robust succession planning and improve employee engagement and empowerment.
This talent strategy allows CMS Energy and Consumers to shape employees’ experience and enable leaders to coach and develop co-workers, source talent, and anticipate and adjust to changing skill sets in the business environment.
Diversity, Equity, and Inclusion
As a part of their Talent Roadmap, CMS Energy and Consumers also employ a comprehensive diversity, equity, and inclusion strategy designed to embed diversity, equity, and inclusion into all aspects of their business. This is done through embedding standards for diversity, equity, and inclusion into all company processes and ensuring these standards are incorporated into all employee experiences. To measure their success, CMS Energy and Consumers utilize select questions in the annual engagement survey to create a diversity, equity, and inclusion index. For the year ended December 31, 2021, the diversity, equity, and inclusion index score was 78 percent; CMS Energy and Consumers have a goal to achieve a score of 80 percent in 2022.
32

Co-workers are also empowered to engage in employee resource groups and events that encourage candid conversations around diversity, equity, and inclusion. There are eight employee resource groups available to all co-workers; these groups are, by date of origin:
the Women’s Advisory Panel, contributing to the achievement of the corporate strategy by supporting the retention, development, and success of women
the Minority Advisory Panel, promoting a culture of diversity and inclusion among all racial and ethnic minorities through education, leadership, development, and networking
the Women’s Engineering Network, connecting and empowering women in the science, technology, engineering, and mathematics fields, while building capabilities to support company objectives
the Veteran’s Advisory Panel, supporting former and active military personnel and assisting in recruiting and retaining veterans through career development
GEN-ERGY, a multigenerational group designed to bridge the gap of learning, networking, and mentoring across the generations of the workforce
the Pride Alliance of Consumers Energy, promoting an inclusive environment that is safe, supportive, and respectful for lesbian, gay, bi-sexual, and transgender persons and allies
capABLE, aimed at removing barriers and creating pathways to meaningful work for employees of all abilities
Interfaith, a space for co-workers of all backgrounds to gather and celebrate their unique beliefs, creating an environment of understanding and respect for all faiths, religions, and spiritual beliefs, including those with no faith affiliation

Item 1A.    Risk Factors
Actual results in future periods for CMS Energy and Consumers could differ materially from historical results and the forward-looking statements contained in this report. Factors that might cause or contributeare exposed to these differences include those discussed in the following sections. CMS Energy’s and Consumers’ businesses are influenced by manya variety of factors, often beyond their control, that are difficult to predict and that involve uncertainties that may materially adversely affect CMS Energy’s or Consumers’ business, liquidity, financial condition, or results and that are often beyond their control.of operations. Additional risks and uncertainties not presently known or that management believes to be immaterial may also adversely affect CMS Energy or Consumers. The risk factors described in the following sections, as well as the other information included in this report and in other documents filed with the SEC, should be considered carefully before making an investment in securities of CMS Energy or Consumers. Risk factors of Consumers are also risk factors of CMS Energy. All of these risk factors are potentially significant.
Investment/Financial Risks
CMS Energy depends on dividends from its subsidiaries to meet its debt service obligations.
Due to its holding company structure, CMS Energy depends on dividends from its subsidiaries to meet its debt service and other payment obligations. If sufficient dividends were not paid to CMS Energy by its subsidiaries, CMS Energy might not be able to generate the funds necessary to fulfill its payment obligations, which could have a material adverse effect on CMS Energy’s liquidity and financial condition.obligations.
Consumers’ ability to pay dividends or acquire its own stock from CMS Energy is limited by restrictions contained in Consumers’ preferred stock provisions and potentially by other legal restrictions, such as certain terms in its articles of incorporation and FERC requirements.


33


CMS Energy has indebtedness that could limit its financial flexibility and its ability to meet its debt service obligations.
The level of CMS Energy’s present and future indebtedness could have several important effects on its future operations, including, among others, that:
a significant portion of CMS Energy’s cash flow from operations could be dedicated to the payment of principal and interest on its indebtedness and would not be available for other purposes
covenants contained in CMS Energy’s existing debt arrangements, which require it to meet certain financial tests, could affect its flexibility in planning for, and reacting to, changes in its business
CMS Energy’s ability to obtain additional financing for working capital, capital expenditures, acquisitions, and general corporate and other purposes could become limited
CMS Energy could be placed at a competitive disadvantage to its competitors that are less leveraged
CMS Energy’s vulnerability to adverse economic and industry conditions could increase
CMS Energy’s future credit ratings could fluctuate
CMS Energy’s ability to meet its debt service obligations and to reduce its total indebtedness will depend on its future performance, which will be subject to general economic conditions, industry cycles, changes in laws or regulatory decisions, and financial, business, and other factors affecting its operations, many of which are beyond its control. CMS Energy cannot make assurances that its businesses will continue to
37

generate sufficient cash flow from operations to service its indebtedness. Ifindebtedness, which could require CMS Energy were unable to generate sufficient cash flows from operations, it could be required to sell assets or obtain additional financing.
CMS Energy and Consumers have financing needs and could be unable to obtain bank financing or access the capital markets.
CMS Energy and Consumers may be subject to liquidity demands under commercial commitments, guarantees, indemnities, letters of credit, and other contingent liabilities. Consumers’ capital requirements are expected to be substantial over the next several years. CMS Energy and Consumers rely on the capital markets, as well as on bank syndications, to meet their financial commitments and short-term liquidity needs if sufficient internal funds are not available from Consumers’ operations and, in the case of CMS Energy, from dividends paid by Consumers and its other subsidiaries. CMS Energy and Consumers also use letters of credit issued under certain of their revolving credit facilities to support certain operations and investments.otherwise funded internally.
Disruptions in the capital and credit markets, as a resultor the inability to obtain required FERC authorization for issuances of uncertainty, changing or increased regulation, or failures of significant financial institutionssecurities including debt, could adversely affect CMS Energy’s and Consumers’ access to liquidity needed for their businesses. Consumers’ inability to obtain prior FERC authorization for any securities issuances, including publicly offered debt, as is required under the Federal Power Act, could adversely affect Consumers’ access to liquidity. Any liquidity disruption could require CMS Energy and Consumers to take measures to conserve cash. These measures could include,cash including, but are not limited to, deferring capital expenditures, changing CMS Energy’s and Consumers’ commodity purchasing strategystrategies to avoid collateral-posting requirements, and reducing or eliminating future share repurchases, dividend payments, or other discretionary uses of cash.
CMS Energy continues to explore financing opportunities to supplement its financial strategy. These potential opportunities include refinancing and/or issuing new debt, preferred stock and/or common equity, commercial paper, and bank financing. Similarly, Consumers may seek funds through the capital


34


markets, commercial lenders, and leasing arrangements. Entering into new financings is subject in part to capital market receptivity to utility industry securities in general and to CMS Energy’s and Consumers’ securities in particular. CMS Energy and Consumers continue to explore financing opportunities to supplement their respective financial strategies. These potential opportunities include refinancing and/or issuing new debt, issuing CMS Energy preferred stock and/or common equity, or entering into commercial paper, bank financing, and leasing arrangements. CMS Energy and Consumers cannot guarantee the capital markets’ acceptance of their securities. CMS Energy may also, from time to time, repurchase (either in open market transactions or through privately negotiated transactions), redeem, or otherwise retire its outstanding debt. Such activities, if any, will depend on prevailing market conditions, contractual restrictions, and other factors. The amounts involved may or may not be material.
Certain of CMS Energy’s and Consumers’ securities and those of their affiliates are rated by various credit rating agencies. A reduction or withdrawal of one or more of its credit ratings could have a material adverse impact on CMS Energy’s or Consumers’ ability to access capital on acceptable terms and maintain commodity lines of credit, could increase itstheir cost of borrowing, and could cause CMS Energy or Consumers to reduce capital expenditures. If iteither or both were unable to maintain commodity lines of credit, CMS Energy or Consumers might have to post collateral or make prepayments to certain suppliers under existing contracts. Further, since Consumers provides dividends to CMS Energy, any adverse developments affecting Consumers that result in a lowering of its credit ratings could have an adverse effect on CMS Energy’s credit ratings.
IfMarket performance and other changes could decrease the value of employee benefit plan assets, which then could require substantial funding.
The performance of various markets affects the value of assets that are held in trust to satisfy future obligations under CMS Energy’s and Consumers’ pension and postretirement benefit plans. CMS Energy and Consumers have significant obligations under these plans and hold significant assets in these trusts. These assets are subject to market fluctuations and will yield uncertain returns, which could fall below CMS Energy’s and Consumers’ forecasted return rates. A decline in the market value of the assets or Consumers were unablea change in the level of interest rates used to obtain bank financing or accessmeasure the capital markets to incur or refinance indebtedness, or were unable to obtain commercially reasonable terms for any financing, thisrequired minimum funding levels could have a material adverse effect on its liquidity, financial condition, and results of operations.
There are risks associated with Consumers’ substantial capital investment program planned forsignificantly increase the next ten years.
Consumers’ planned investments include the construction or acquisition of power generation, electric and gas infrastructure, conversions and expansions, environmental controls, electric grid modernization technology, and other electric and gas investments to upgrade delivery systems, as well as decommissioning of older facilities. The successfunding requirements of these capital investments depends on or could be affected by a variety of factors that include, but are not limited to:
effective pre-acquisition evaluation of asset values, future operating costs, potential environmental and other liabilities, and other factors beyond Consumers’ control
effective cost and schedule management of new capital projects
availability of qualified construction personnel
obligations. Also, changes in commodity and other prices

It is possible that adverse events associated with these factors could have a material adverse effect on Consumers’ liquidity, financial condition, and results of operations.Industry/Regulatory Risks
Changes to ROA could have a material adverse effect on CMS Energy’s and Consumers’ businesses.
Michigan law allows electric customers in Consumers’ service territory to buy electric generation service from alternative electric suppliers in an aggregate amount capped at ten percent of Consumers’ sales, with certain exceptions. Presently, theThe proportion of Consumers’ electric deliveries under the ROA program and on the ROA waiting list is 27over ten percent. Consumers’ rates are regulated by the MPSC, while alternative electric suppliers charge market-based rates, putting competitive pressure on Consumers’ electric supply. If the ROA limit were increased or if electric generation service in Michigan were deregulated, it could have a material adverse effect on CMS Energy and Consumers.
Distributed energy resources could have a material adverse effect on CMS Energy’s and Consumers’ financial resultsbusinesses.
Michigan law allows customers to use distributed energy resources for their electric energy needs. These distributed energy resources are connected to Consumers’ electric grid. The state distributed generation program is currently capped by the 2016 Energy Law at one percent of utilities’ peak loads, but Consumers has voluntarily agreed to increase the cap to two percent on its system. Consumers is required to purchase distributed generation customers’ excess generation at rates determined by the MPSC. Recent FERC policy will also soon allow many customer-owned behind-the-meter and operations.


35


distributed energy resources could result in a reduction of Consumers’ electric sales. Third parties’ operations of distributed energy resources could also potentially have a negative impact on the stability of the grid. An increase in customers’ use of distributed energy resources, and the rate structure for distributed energy resources customers’ use of Consumers’ system and Consumers’ purchases of their excess generation, could have a material adverse effect on CMS Energy and Consumers.
CMS Energy and Consumers are subject to rate regulation, which could have ana material adverse effect on financial results.
CMS Energy and Consumers are subject to rate regulation. Consumers’ electric and gas retail rates are set by the MPSC and cannot be changed without regulatory authorization. If rate regulators fail to provide adequate rate relief, it could have a material adverse effect on Consumers or Consumers’ plans for making significant capital investments. Regulators seeking to avoid or minimize rate increases could resist raising customer rates sufficiently to permit Consumers to recover the full cost of these investments. In addition, because there are statutory requirements mandating that regulators allow Consumers to recover from customers certain costs, such as resource additions to meet Michigan’s renewable resource standard, energy waste reduction, and environmental compliance, regulators could be more inclined to oppose rate increases for other requested items and investments. Rate regulators could also face pressure to avoid or limit rate increases for a number of reasons, including an economic downturn in the state or diminishment of Consumers’ customer base. In addition to its potential effects on Consumers’ investment program, any limitation of cost recovery through rates could have a material adverse effect on Consumers’ liquidity, financial condition, and results of operations.
Orders of the MPSC could limit recovery of costs of providing service including, but not limited to, environmental and safety related expenditures for coal-fueled plants and other utility properties, regulatory assets, power supply and natural gas supply costs, operating and maintenance expenses, additional utility-based investments, sunk investment in mothballed or retired generating plants, costs associated with the proposed retirement and decommissioning of facilities, depreciation expense, MISO energy and transmission costs, costs associated with energy waste reduction investments and state or federally mandated renewable resource standards, or expenditures subject to tracking mechanisms.service. These orders could also result in adverse regulatory treatment of other matters. For example, MPSC orders could prevent or curtail Consumers from shutting off non‑paying customers or could prevent or curtaillimit the implementation of a gas revenue mechanism.
FERC authorizes certain subsidiaries of CMS Energy to sell wholesale electricity at market-based rates. Failure of these subsidiaries to maintain this FERC authority could have a material adverse effect on CMS Energy’s and Consumers’ liquidity, financial condition, and results of operations. Transmission rates paid by Consumers and other CMS Energy subsidiaries are also set by FERC. FERC, orders related toas are the tariff terms governing the participation of Consumers and other CMS Energy subsidiaries in FERC-regulated wholesale electricity markets operated by regional transmission costs could have a material adverse effect on Consumers’ liquidity, financial condition,organizations and resultsindependent system operators such as MISO and PJM.At least one CMS Energy subsidiary participates in the wholesale electricity markets operated by ERCOT, over which FERC has limited control.
39

The various risks associated with the MPSC and FERC regulation of CMS Energy’s and Consumers’ businesses, which include the risk of adverse decisions in any number of rate or regulatory proceedings before either agency, as well as judicial proceedings challenging any agency decisions, could have a material adverse effect on CMS Energy’sEnergy and Consumers’ liquidity, financial condition, investment plans,Consumers. Changes to the tariffs or business practice manuals of certain wholesale market operators such as MISO, PJM, or ERCOT could also have a material adverse effect on CMS Energy and results of operations.Consumers.
Utility regulation, state or federal legislation, and compliance could have a material adverse effect on CMS Energy’s and Consumers’ businesses.
CMS Energy and Consumers are subject to, or affected by, extensive utility regulation and state and federal legislation. If it were determined that CMS Energy andor Consumers believe that theyfailed to comply with applicable laws and regulations. If it were determined thatregulations, they failed to comply, CMS Energy or Consumers could become subject to fines, penalties, or disallowed costs, or be required to implement additional compliance, cleanup, or remediation programs, the cost of which could be material. AdoptionCMS Energy and Consumers cannot predict the impact of new laws, rules, regulations, principles, or practices by federal or state agencies or wholesale electricity market operators, or challenges or changes to present laws, rules, regulations, principles, or practices and the interpretation of any adoption or change, could have a material adverse effect on CMS Energy’s and Consumers’ liquidity, financial condition, and results of

Utility regulation could be impacted by various matters, such asFERC, through NERC and its delegated regional entities, oversees reliability of certain portions of the electric industry restructuring, hydro relicensing, asset reclassification, gas pipeline capacity and gas storage, new generation facilities or investments, transmission charges, environmental controls, climate change, air emissions, renewable energy, energy policy and ROA, distributed generation, battery storage, regulation or deregulation, energy capacity standards or markets, reliability, and safety.grid. CMS Energy and Consumers cannot predict the impact of these mattersFERC orders or actions of NERC and its regional entities on electric system reliability. Additionally, national gas pipeline infrastructure has recently been under scrutiny following disruptions related to extreme weather and cyber incidents. In 2021, the Transportation Security Administration issued two mandatory security directives related to natural gas pipelines that apply to Consumers. Additional regulation in this area could adversely affect Consumers’ gas operations.
CMS Energy and Consumers have announced an ambitious plan to reduce their liquidity,impact on climate change. Achieving this plan depends on numerous factors, many of which are outside of their control.
Consumers has announced a long-term strategy for delivering clean, reliable, resilient, and affordable energy, including a plan to end coal use in 2025 as set forth in the 2021 IRP. The MPSC, FERC, other regulatory authorities, or other third parties may prohibit, delay, impair, or deny approval or consent of the 2021 IRP and some or all of the 2021 IRP-associated natural gas-fueled plant acquisitions, or deny reasonable rate recovery of the undepreciated plant balances associated with the retirement of coal-fueled plants necessary to proceed with the 2021 IRP. Consumers may be unable to acquire, site, and/or permit some or all of the generation capacity proposed in the 2021 IRP. Consumers’ ability to implement the 2021 IRP may be affected by global supply chain disruptions and changes in the cost, availability, and supply of generation capacity. Advancements in technology related to items such as battery storage and electric vehicles may not become commercially available or economically feasible as projected in the 2021 IRP. Customer programs such as energy efficiency and demand response may not realize the projected levels of customer participation. CMS Energy and Consumers could suffer financial condition,loss, reputational damage, litigation, or other negative repercussions if they are unable to achieve their ambitious plan.
Changes in taxation as well as the inherent difficulty in quantifying potential tax effects of business decisions could negatively impact CMS Energy and Consumers.
CMS Energy and Consumers are required to make judgments regarding the potential tax effects of various financial transactions and results of operations.operations in order to estimate their obligations to taxing

Additionally, changes in federal, state, or local tax rates or other changes in tax laws could have adverse impacts.
CMS Energy’s or Consumers’ liquidity, financial condition,Energy and resultsits subsidiaries, including Consumers, must comply with the Dodd-Frank Act and its related regulations.
The Dodd-Frank Act provides for regulation by the Commodity Futures Trading Commission of operations.certain commodity-related contracts. Although CMS Energy, Consumers, and certain subsidiaries of CMS Enterprises qualify for an end-user exception from mandatory clearing of commodity-related swaps, these regulations could affect the ability of these entities to participate in these markets and could add additional regulatory oversight over their contracting activities.
CMS Energy and Consumers could incur substantial costs to comply with environmental requirements.
CMS Energy and Consumers are subject to costly and stringent environmental regulations that will likely require additional significant capital expenditures for emissions control equipment, CCR disposal and storage, cooling water intake equipment, effluent treatment, and PCB remediation. In addition, regulatory action on PFAS at the state and/or federal level could cause CMSEnergy and Consumers to further test and remediate some sites if PFAS is present at certain levels. Present and reasonably anticipated state and federal environmental statutes and regulations will continue to have a material effect on CMS Energy and Consumers.
CMS Energy and Consumers have interests in fossil-fuel-fired power plants, and other types of power plants, and natural gas systems that produceemit greenhouse gases. Federal and state environmental laws and rules, as well as international accords and treaties, could require CMS Energy and Consumers to install additional equipment for emission controls, undertake heat-rate improvement projects, purchase carbon emissions allowances, curtail operations, invest in generating capacity with fewer carbon dioxide emissions, or take other significant steps to manage or lower the emission of greenhouse gases.
The following risks related to climate change, emissions, and environmental regulations could also have a material adverse impact on CMS Energy’sEnergy and Consumers’ liquidity, financial condition, and results of operations:Consumers:
litigation originated by third parties against CMS Energy or Consumers due to CMS Energy’s or Consumers’ greenhouse gas or other emissions or CCR disposal and storage
impairment of CMS Energy’s or Consumers’ reputation due to their greenhouse gas or other emissions and public perception of their response to potential environmental regulations, rules, and legislation
extreme weather conditions, such as severe storms or flooding, that may affect customer demand, company operations, or assets
Consumers retired seven smaller coal-fueled electric generating units in 2016. Consumers may encounter previously unknown environmental conditions that will need to be addressed in a timely fashion with state and federal environmental regulators as facilities and equipment on these sites are taken out of service.
Consumers expects to collect fully from its customers, through the ratemaking process, expenditures incurred to comply with environmental regulations, but cannot guarantee this outcome. If Consumers were unable to recover these expenditures from customers in rates, it could negatively affect


37


CMS Energy’s or Consumers’ liquidity, results of operations, and financial condition and CMS Energy or Consumers could be required to seek significant additional financing to fund these expenditures.

Management’s Discussion and Analysis of Financial Condition and Results of Operations—Outlook—Consumers Electric Utility Outlook and Uncertainties.Outlook.
CMS Energy’s and Consumers’ businesses could be affected adversely by any delay in meeting environmental requirements.
A delay or failure by CMS Energy or Consumers to obtain or maintain any necessary environmental permits or approvals to satisfy any applicable environmental regulatory requirements or install emission or pollution control equipment could:
prevent the construction of new facilities
prevent the continued operation and sale of energy from existing facilities
prevent the suspension of operations at existing facilities
prevent the modification of existing facilities
result in significant additional costs that could have a material adverse effect on their liquidity, financial condition, and results of operations
CMS Energy and Consumers expect to incur additional substantial costs related to remediation of legacy environmental sites.
Consumers expects to incur additional substantial costs related to the remediation of its former MGP sites and other response activity costs at a number of other sites, including, but not limited to, sites of retired coal-fueled electric generating units, under NREPA and CERCLA. Consumers believes these costs should be recoverable in rates, but cannot guarantee that outcome.

CMS Energy and Consumers could be affected adversely by legacy litigation and retained liabilities.
CMS Energy, CMS MST, CMS Field Services, Cantera Natural Gas, Inc., and Cantera Gas Company were named as defendants in various lawsuits arising as a result of alleged inaccurate natural gas price reporting. Remaining allegations include price-fixing conspiracies, restraint of trade, and artificial inflation of natural gas retail prices in Kansas and Wisconsin. CMS Energy cannot predict the outcome of these lawsuits or the amount of damages for which CMS Energy may be liable. It is possible that the outcome of the lawsuits could have a material adverse effect on CMS Energy’s liquidity, financial condition, and results of operations.

Many of these contingent liabilities can remain open for extended periods of time after the sales are closed. Depending on the extent to which the buyers might ultimately seek to enforce their rights under these contractual provisions, and the resolution of any disputes concerning them, there could be a material adverse effect on CMS Energy’s or Consumers’ liquidity, financial condition, and results of operations.
In 2002, CMS Energy sold its oil, gas, and methanol investments in Equatorial Guinea. The government of Equatorial Guinea claims that, in connection with the sale, CMS Energy owes $152 million in taxes, plus substantial penalties and interest that could be up to or exceed the amount of the taxes claimed. In 2015, the matter was proceeding to formal arbitration; however, since then, the government of Equatorial Guinea has stopped communicating.communicating with CMS Energy. CMS Energy has concluded that the government’s tax claim is without merit and will continuebelieves the likelihood of material loss to contest the claim,be remote, but cannot predict the financial impact or outcome of the matter.

CMS Energy’s and Consumers’ energy sales and operations are affected by seasonal factors and varying weather conditions from year to year.
CMS Energy’s and Consumers’ utility operations are seasonal. The consumption of electric energy typically increases in the summer months, due primarily to the use of air conditioners and other cooling equipment, while peak demand for natural gas typically occurs in the winter due to colder temperatures and the resulting use of natural gas as heating fuel. Accordingly, CMS Energy’s and Consumers’ overall results may fluctuate substantially on a seasonal basis. Mild temperatures during the summer cooling season and winter heating season as well as the impact of extreme weather events on Consumers’ system could have a material adverse effect on CMS Energy’s and Consumers’ liquidity, financial condition, and results of operations.
Consumers is exposed to risks related to general economic conditions in its service territories.

In addition, economic conditions in Consumers’ service territory affect its collections of accounts receivable and levels of lost or stolen gas, which in turn impact its liquidity, financial condition, and results of operations.effect.
CMS Energy and Consumers are subject to information security risks, risks of unauthorized access to their systems, and technology failures.
In the regular course of business, CMS Energy and Consumers handle a range of sensitive confidential security and customer information. CMS Energy and Consumers are subject to laws and rules issued by various agencies concerning safeguarding and maintaining the confidentiality of this information. A security breach of CMS Energy’s and Consumers’ information or control systems could involve theft or the


39


inappropriate release of certain types of information, such as confidential customer information or, separately, system operating information. These events could disrupt operations, subject CMS Energy and Consumers to possible financial liability, damage their reputation and diminish the confidence of customers, and have a material adverse effect on CMS Energy’s and Consumers’ liquidity, financial conditions, and results of operations.
In addition, CMS Energy and Consumers operate in a highly regulated industry that requires the continued operation of sophisticated information and control technology systems and network infrastructure. Despite implementation of security measures, technology systems, including disaster recovery and backup systems, are vulnerable to failure, cyber crime, unauthorized access, and being disabled. These events could impact the reliability of electric generation and electric and gas delivery and also subject CMS Energy and Consumers to financial harm. Cyber crime, which includes the use of malware, computer viruses, and other means for disruption or unauthorized access against companies, including CMS Energy and Consumers, has increasedis increasing in frequency, scope, and potential impact in recent years.impact. While CMS Energy and Consumers have not been subject to cyber crime incidents that have had a material impact on their operations to date, their security measures in place may be insufficient to prevent a major cyber incident in the future. If technology systems, including disaster recovery and backup systems, were to fail or be breached, CMS Energy and Consumers might not be able to fulfill critical business functions, and sensitive confidential and proprietary data could be compromised, which could have a material adverse effect on CMS Energy’s and Consumers’ liquidity, financial condition, and results of operations.compromised. In addition, because CMS Energy’s and Consumers’ generation, transmission, and distribution systems are part of an interconnected system, a disruption caused by a cyber incident at another utility, electric generator, system operator, or commodity supplier could also adversely affect CMS Energy’sEnergy or Consumers’ businesses, financial condition, and results of operations.Consumers.
A variety of technological tools and systems, including both company-owned information technology and technological services provided by outside parties, support critical functions. The failure of these technologies, including backup systems, or the inability of CMS Energy and Consumers to have these technologies supported, updated, expanded, or integrated into other technologies, could hinder their business operations and materially adversely affect their liquidity, financial condition, and results of operations. A breach or failure of technology, including disaster recovery or backup systems, could also have a negative impact on CMS Energy’s banking subsidiary, EnerBank.
CMS Energy’s and Consumers’ businesses have liability risks.
Consumers’ electric and gas delivery systems, power plants, gas infrastructure including storage facilities, wind energy or solar equipment, and energy products, and the independent power plants owned in whole or in part by CMS Energy could be involved in incidents, failures, or accidents that result in injury, loss of life, or property loss to customers, employees, or the public. Although CMS Energy and Consumers have insurance coverage for many potential incidents (subject to deductibles, limitations, and self-insurance amounts that could be material), depending upon the nature or severity of any incident, failure, or accident, CMS Energy or Consumers could suffer financial loss, reputational damage, and negative repercussions from regulatory agencies or other public authorities.

beyond what could be recovered through insurance policies (which are subject to deductibles, limitations, and limits)self-insurance amounts that could be material), could require CMS Energy and Consumers to incur significant upfront costs, and could severely disrupt operations, resulting in loss of service to customers. There is also a risk that regulators could, after the fact, conclude that Consumers’ preparedness or response to such an event was inadequate and take adverse actions as a result.
CMS Energy and Consumers are exposed to significant reputational risks.
CMS Energy and Consumers could suffer negative impacts to their reputations as a result of operational incidents, violations of corporate policies, regulatory violations, inappropriate use of social media, or other events. Reputational damage could have a material adverse effect on CMS Energy’s and Consumers’ liquidity, financial condition, and results of operations. It could also result in negative customer perception and increased regulatory oversight.
Consumers is exposed to changes in customer usage that could impact financial results.
Distributed electricity generation: Technology advances, government incentives and subsidies, and recent regulatory decisions could increase the cost effectiveness of customer-owned methods of producing electricity and managing energy use, such as fuel cells, batteries, microturbines, wind turbines, and solar photovoltaics, resulting in reduced load, cross subsidization, and increased costs. This could have a material adverse effect on CMS Energy’s and Consumers’ liquidity, financial condition, and results of operations.
Energy waste reduction: Customers could reduce their consumption through demand-side energy conservation and energy waste reduction programs. These reductions could have a material adverse effect on CMS Energy’s and Consumers’ liquidity, financial condition, and results of operations.
Energy risk management strategies might not be effective in managing fuel and electricity pricing risks, which could result in unanticipated liabilities to CMS Energy and Consumers or increased volatility in their earnings.
CMSEnergy and Consumers are exposed to changes in market prices for commodities including, but not limited to, natural gas, coal, electric capacity, electric energy, emission allowances, gasoline, diesel fuel, and RECs. Prices for these commodities may fluctuate substantially over relatively short periods of time and expose CMSEnergy and Consumers to price risk. CMSEnergy and Consumers manage commodity price risk using established policies and procedures, and they may use various contracts to manage this risk, including swaps, options, futures, and forward contracts. No assurance can be made that these strategies will be successful in managing CMSEnergy’s and Consumers’ risk or that they will not result in net liabilities to CMSEnergy or Consumers as a result of future volatility.
A substantial portion of Consumers’ operating expenses for its electric generating plants and vehicle fleet consists of the costs of obtaining these commodities. The contracts associated with Consumers’ fuel for electric generation and purchased power are executed in conjunction with the PSCR mechanism, which is designed to allow Consumers to recover prudently incurred costs associated with its positions in these commodities. If the MPSC determined that any of these contracts or related contracting policies were imprudent, recovery of these costs could be disallowed.
Natural gas prices in particular have been historically volatile. Consumers routinely enters into contracts for natural gas to mitigate exposure to the risks of demand, market effects of weather, and changes in commodity prices associated with itsthe gas distribution business. These contracts are executed in conjunction with the GCR mechanism, which is designed to allow Consumers to recover prudently incurred costs associated with its


41


natural gas positions. If the MPSC determined that any of these contracts or related contracting policies were imprudent, recovery of these costs could be disallowed.
CMSEnergy and Consumers do not always hedge any or all of the exposure of their operations from commodity price volatility. Furthermore, the ability to hedge exposure to commodity price volatility depends on liquid commodity markets. As a result, to the extent the commodity markets are illiquid, CMSEnergy and Consumers might not be able to execute their risk management strategies, which could result in larger unhedged positions than preferred at a given time. To the extent that unhedged positions exist, fluctuating commodity prices could have a negative effect on CMS Energy’sEnergy and Consumers’ liquidity, financial condition, and results of operations.Consumers. Changes in laws that limit CMSEnergy’s and Consumers’ ability to hedge could also have a negative effect on CMS Energy’s and Consumers’ liquidity, financial condition, and results of operations.
CMS Energy and Consumers are exposed to counterparty risk.
Adverse economic conditions or financial difficulties experienced by counterparties with whom CMS Energy and Consumers do business could impair the ability of these counterparties to pay for CMS Energy’s and Consumers’ services and/or fulfill their contractual obligations, including performance and payment of damages. CMS Energy and Consumers depend on these counterparties to remit payments and perform contracted services in a timely fashion. Any delay or default in payment or performance of contractual obligations could have a material adverse effect on CMS Energy’s and Consumers’ liquidity, financial condition, and results of operations.
Volatility and disruptions in capital and credit markets could have a negative impact on CMS Energy’s and Consumers’ lenders, vendors, contractors, suppliers, customers, and other counterparties, causing them to fail to meet their obligations. Adverse economic conditions could also have a negative impact on the loan portfolio of CMS Energy’s banking subsidiary, EnerBank.Consumers.
Consumers might not be able to obtain an adequate supply of natural gas or coal, which could limit its ability to operate its electric generation facilities or serve its natural gas customers.
Consumers has natural gas and coal supply and transportation contracts in place for the natural gas and coal it requires for its electric generating capacity. Consumers also has interstate transportation and
45

supply agreements in place to facilitate delivery of natural gas to its customers. Apart from the contractual and monetary remedies available to Consumers in the event of a counterparty’s failure to perform under any of these contracts, there can be no assurances that the counterparties to these contracts will fulfill their obligations to provide natural gas or coal to Consumers. The counterparties under the agreements could experience financial or operational problems that inhibit their ability to fulfill their obligations to Consumers. In addition, counterparties under these contracts might not be required to supply natural gas or coal to Consumers under certain circumstances, such as in the event of a natural disaster or severe weather.
If for its electric generating capacity, Consumers were unable to obtain its natural gas or coal requirements, or for its natural gas delivery to customers, Consumers were unable to obtain its natural gas supply requirements, it could be required to purchase natural gas or coal at higher prices or implement its natural gas curtailment program filed with the MPSC. These alternatives
Unplanned outages or maintenance could increasebe costly for CMS Energy or Consumers.
Unforeseen outages or maintenance of the electric and gas delivery systems, power plants, gas infrastructure including storage facilities and compression stations, wind energy or solar equipment, and energy products owned in whole or in part by CMS Energy or Consumers may be required for many reasons. When unplanned outages occur, CMS Energy and Consumers will not only incur unexpected maintenance expenses, but may also have to make spot market purchases of electric and gas commodities that may exceed CMS Energy’s or Consumers’ working capital requirementsexpected cost of generation or gas supply, be forced to curtail services, or retire a given asset if the cost or timing of the maintenance is not reasonable and prudent. Unplanned generator outages could reduce the capacity credit CMS Energy or Consumers receives from MISO and could decrease its revenues.

The COVID‑19 pandemic has had widespread impacts on people, businesses, economies, and financial markets globally, in the U.S., and in markets where CMS Energy and Consumers conduct business. Future impacts of the pandemic could include a prolonged reduction in economic activity, extended disruption to supply chains and operations, increased labor costs, and reduced availability of labor and productivity. CMS Energy and Consumers provide essential services, which means that CMS Energy and Consumers must keep employees, who operate facilities or interact with customers, safe and minimize unnecessary risk of exposure to COVID‑19. CMS Energy and Consumers have significant obligations under these planstaken extra precautions in an effort to protect the health of employees working in the field and hold significant assets in these trusts. These assets are subject to market fluctuations and will yield uncertain returns, which could fall below CMS Energy’s and Consumers’ forecasted return rates. A decline in the market value of the assets or a change in the level of interest rates used to measure the required minimum funding levels could significantly increase the funding requirements of these obligations. Also, changes in demographics, including an increased number of retirements or changes in life expectancy assumptions, could significantly increase the funding requirements of the obligations related to the pension and postretirement benefit plans.

This remains an evolving situation; CMS Energy and Consumers will continue to managemonitor developments and will take additional necessary precautions in order to keep employees, customers, contractors, and communities safe.
The ultimate impact of the COVID‑19 pandemic depends on factors beyond CMS Energy’s and Consumers’ knowledge or control. The degree to which COVID‑19 will ultimately impact CMS Energy and Consumers will depend in part on future developments, including the severity and duration of COVID-19 and its variants, actions or inactions that may be taken by governmental authorities, including, but not limited to, COVID-19 vaccination and testing requirements, and to what extent and when normal economic and operational conditions can resume.

General Risk Factors
CMS Energy and Consumers are exposed to counterparty risk.
Adverse economic conditions or financial difficulties experienced by counterparties with whom CMS Energy and Consumers do business could impair the ability of these counterparties to pay for CMS Energy’s and Consumers’ services and/or fulfill their pensioncontractual obligations, including performance and postretirement plan assets successfully, itpayment of damages. CMS Energy and Consumers depend on these counterparties to remit payments and perform contracted services in a timely fashion. Any delay or default in payment or performance of contractual obligations could have a material adverse effect on CMS Energy and Consumers.
Volatility and disruptions in capital and credit markets could have a negative impact on CMS Energy’s and Consumers’ lenders, vendors, contractors, suppliers, customers, and other counterparties, causing them to fail to meet their liquidity, financial condition,obligations.
CMS Energy and resultsConsumers are exposed to significant reputational risks.
CMS Energy and Consumers could suffer negative impacts to their reputations as a result of operations.operational incidents, violations of corporate policies, regulatory violations, inappropriate use of social media, or other events. Reputational damage could have a material adverse effect and could result in negative customer perception and increased regulatory oversight.
A work interruption or other union actions could adversely affect Consumers.
Unions represent 3742 percent of Consumers’ employees. Consumers’ union agreements expire in 2020.2025. If these employees were to engage in a strike, work stoppage, or other slowdown, Consumers could experience a significant disruption in its operations and higher ongoing labor costs.
Failure to attract and retain an appropriately qualified workforce could adversely impact CMS Energy’s and Consumers’ results of operations.
The workforce of CMS Energy and Consumers is aging and a number of employees will become eligible to retire within the next few years. In some areas, competition for skilled employees is high and if CMS Energy and Consumers were unable to match skill sets to future needs, they could encounter operating challenges and increased costs. These challenges could include a lack of resources, loss of knowledge, and delays in skill development. Additionally, higher costs could result from the use of contractors to replace employees, loss of productivity, and safety incidents. Failing to train replacement employees adequately and to transfer internal knowledge and expertise could adversely affect CMS Energy’s and Consumers’ ability to manage and operate their businesses. If CMS Energy and Consumers were unable to attract and retain an appropriately qualified workforce, their financial condition and results of operations could be affected negatively.
Unplanned outages or maintenance could be costly for CMS Energy or Consumers.
Unforeseen outages or maintenance of the independent power plants owned in whole or in part by CMS Energy or Consumers’ electric and gas delivery systems, power plants, gas infrastructure including storage facilities, wind energy or solar equipment, and energy products may be required for many reasons. These reasons could include catastrophic events such as fires, explosions, extreme weather, floods or other acts of God, failures of equipment or materials, operator error, or the need to comply with environmental or safety regulations. When unplanned outages occur, CMS Energy and Consumers will not only incur unexpected maintenance expenses, but may also have to make spot market purchases of electric and gas commodities that may exceed CMS Energy’s or Consumers’ costs of generation or service, be forced to curtail services, or retire a given unit if the cost or timing of the maintenance is not reasonable and prudent. Unplanned outages could reduce the capacity credit CMS Energy or Consumers receives from MISO and could cause CMS Energy or Consumers to incur additional capacity costs in future years. Costs associated with these matters could have a material adverse effect on CMS Energy’s or Consumers’ liquidity, financial condition, and results of operations.


43


Changes in taxation as well as the inherent difficulty in quantifying potential tax effects of business decisions could negatively impact CMS Energy and Consumers.
CMS Energy and Consumers are required to make judgments regarding the potential tax effects of various financial transactions and results of operations in order to estimate their obligations to taxing authorities. The tax obligations include income taxes, real estate taxes, sales and use taxes, employment-related taxes, and ongoing issues related to these tax matters. The judgments include determining reserves for potential adverse outcomes regarding tax positions that have been taken and may be subject to challenge by the IRS and/or other taxing authorities. Unfavorable settlements of any of the issues related to these reserves or other tax matters at CMS Energy or Consumers could have a material adverse effect on their liquidity, financial condition, and results of operations.
CMS Energy and Consumers are subject to changing tax laws. Changes in federal, state, or local tax rates or other changes in tax laws could have adverse impacts on their liquidity, financial condition, and results of operations.
In December 2017, the TCJA, which changed existing federal tax law and included numerous provisions that affect businesses, was enacted. CMS Energy and Consumers made reasonable estimates in measuring and accounting for the effects of the TCJA and did not recognize any material changes to their estimates during the years ended December 31, 2019 and December 31, 2018. Given expected changes to U.S. Treasury regulations and interpretations of the TCJA by the U.S. Treasury, the final transition impacts of the TCJA may differ from the estimates provided elsewhere in this report.
CMS Energy and its subsidiaries, including Consumers and EnerBank, must comply with the Dodd-Frank Act and its related regulations, which are subject to change and could involve material costs or affect operations.
Regulations that are intended to implement the Dodd-Frank Act have been and are still being adopted and modified by the appropriate agencies. The Dodd-Frank Act added a new Section 13 to the Bank Holding Company Act. Known, together with its implementing regulations, as the Volcker Rule, it generally restricts certain banking entities (such as EnerBank) and their subsidiaries or affiliates from engaging in proprietary trading activities and from owning equity in or sponsoring any private equity or hedge fund. The activities of CMS Energy and its subsidiaries (including EnerBank) have not been and are not expected to be materially affected by the Volcker Rule; however, they are restricted from engaging in proprietary trading, investing in third‑party hedge or private equity funds, and sponsoring these funds in the future unless CMS Energy qualifies for an exemption from the rule. CMS Energy and its subsidiaries are also subject to certain ongoing compliance requirements pursuant to the regulations. CMS Energy cannot predict the full impact of the Volcker Rule, including any impact resulting from changes to implementing regulations, on CMS Energy’s or EnerBank’s operations or financial condition.
All companies that directly or indirectly control an FDIC-insured bank are required to serve as a source of financial strength for that institution. As a result, CMS Energy could be called upon by the FDIC to infuse additional capital into EnerBank to the extent that EnerBank fails to satisfy its capital requirements. In addition, CMS Energy is contractually required (i) to make cash capital contributions to EnerBank in the event that EnerBank does not maintain required minimum capital ratios and (ii) to provide EnerBank financial support, in an amount and duration as may be necessary for EnerBank to meet the cash needs of its depositors and other operations.
In addition, the Dodd-Frank Act provides for regulation by the Commodity Futures Trading Commission of certain commodity-related contracts. Although CMS Energy, Consumers, EnerBank, and certain subsidiaries of CMS Enterprises qualify for an end-user exception from mandatory clearing of


44


commodity-related swaps, these regulations could affect the ability of these entities to participate in these markets and could add additional regulatory oversight over their contracting activities.

Item 7.    Management’s Discussion and Analysis of Financial Condition and Results of Operations
This Management’s Discussion and Analysis of Financial Condition and Results of Operations is a combined report of CMS Energy and Consumers.
Executive Overview
CMS Energy is an energy company operating primarily in Michigan. It is the parent holding company of several subsidiaries, including Consumers, an electric and gas utility; and CMS Enterprises, primarily a domestic independent power producer and marketer; andmarketer. CMS Energy was also the parent holding company of EnerBank, an industrial bank located in Utah.Utah, until October 1, 2021 when EnerBank was acquired by Regions Bank as described below. Consumers’ electric utility operations include the generation, purchase, transmission, distribution, and sale of electricity, and Consumers’ gas utility operations include the purchase, transmission, storage, distribution, and sale of natural gas. Consumers’ customer base consists of a mix of primarily residential, commercial, and diversified industrial customers. CMS Enterprises, through its subsidiaries and equity investments, is engaged in domestic independent power production, including the development and operation of renewable generation, and the marketing of independent power production.
On October 1, 2021, EnerBank provides unsecured consumer installment loans, largely for financing home improvements.was acquired by Regions Bank. CMS Energy received proceeds of over $1 billion from the transaction and recognized a pre-tax gain of $657 million. CMS Energy intends to use the proceeds from the sale to fund key initiatives in its core energy business related to safety, reliability, and its clean energy transformation.
CMS Energy and Consumers manage their businesses by the nature of services each provides. CMS Energy operates principally in fourthree business segments: electric utility; gas utility; and enterprises, its non‑utility operations and investments; and EnerBank.investments. As a result of the sale described above, EnerBank is no longer included in the composition of CMS Energy’s reportable segments. EnerBank’s results of operations through the date of the sale are presented as income from discontinued operations. Consumers operates principally in two business segments: electric utility and gas utility. CMS Energy’s and Consumers’ businesses are affected primarily by:
regulation and regulatory matters
state and federal legislation
economic conditions
weather
energy commodity prices
interest rates
their securities’ credit ratings
The Triple Bottom Line
CMS Energy’s and Consumers’ purpose is to achieve world class performance while delivering hometown service. In support of this purpose, the companiesCMS Energy and Consumers employ the “Consumers Energy“CE Way,” a lean operating model designed to improve safety, quality, cost, delivery, and employee morale.


50


CMS Energy and Consumers measure their progress toward the purpose by considering their impact on the “triple bottom line” of people, planet, and profit, which is underpinned by performance; this consideration takes into account not only the economic value that the companiesCMS Energy and Consumers create for customers and investors, but also their responsibility to social and environmental goals. The triple bottom
51

line balances the interests of the companies’ employees, customers, suppliers, regulators, creditors, Michigan’s residents, the investment community, and other stakeholders, and it reflects the broader societal impacts of the companies’CMS Energy’s and Consumers’ activities.
graphic-cmsppp.jpgcms-20211231_g8.jpg
Consumers’CMS Energy’s Environmental, Social, Governance and Sustainability Report, which is available to the public, describes the company’sCMS Energy’s and Consumers’ progress toward world class performance measured in the areas of people, planet, and profit.
People: The people element of the triple bottom line represents CMS Energy’s and Consumers’ commitment to their employees, their customers, the residents of local communities in which the companiesthey do business, and other stakeholders.
The safety of employees, customers, and the general public is a priority of CMS Energy and Consumers. Accordingly, CMS Energy and Consumers have worked to integrate a set of safety principles into their business operations and culture. These principles include complying with applicable safety, health, and security regulations and implementing programs and processes aimed at continually improving safety and security conditions. Over the last ten years,Since 2010, Consumers’ OSHA recordable incident rate has decreased by over 6340 percent.
In response to the COVID-19 pandemic, CMS Energy and Consumers have issued a response plan that is focused on the health, safety, and well-being of their co-workers, customers, and communities. CMS Energy and Consumers have aligned with safety and health guidelines from the CDC, OSHA, MIOSHA, and the Michigan Department of Health and Human Services in order to protect their employees, customers, and contractors to ensure the continued delivery of critical energy services.
In addition, while CMS Energy and Consumers have not yet experienced significant labor or supply chain disruption as a result of the COVID-19 pandemic, they continue to monitor minor disruptions and take steps to mitigate against future impacts in order to continue to provide safe and reliable service to customers.
CMS Energy and Consumers also place a high priority on customer value and on providing a hometown customer experience. Consumers’ customer-driven investment program is aimed at improving safety and increasing electric and gas reliability, which has resulted in measurable improvements in customer satisfaction.
In 2021, Consumers filed an updated Electric Distribution Infrastructure Investment Plan with the MPSC, which outlines a five-year strategy to improve its electric distribution system and the reliability of the grid. The plan dedicates over $1 billion annually to projects that will reduce the number and duration of power outages to customers through investment in infrastructure upgrades, forestry management, and grid modernization.
52

Central to Consumers’ commitment to its customers are the initiatives it has undertaken to keep electricity and natural gas affordable, including:
replacement of coal-fueled generation and PPAs with a cost-efficient mix of renewable energy and energy waste reduction and demand response programs
targeted infrastructure investment to reduce maintenance costs and improve reliability and safety
supply chain optimization
economic development to increase sales and to reduce maintenance costsoverall rates
information and control system efficiencies
employee and retiree health care cost sharing
workforce productivity enhancements
In addition, Consumers’ gas commodity costs declined by 6252 percent from 2009 through 2019,over the last ten years, due not only to a decrease in market prices but also to Consumers’ improvements to its gas infrastructure and optimization of its gas purchasing and storage strategy. These gas commodity savings are passed on to customers.
Planet: The planet element of the triple bottom line represents CMS Energy’s and Consumers’ commitment to protect the environment. This commitment extends beyond compliance with various state and federal environmental, health, and safety laws and regulations. Management considers climate change


51


and other environmental risks in the companies’ strategy development, business planning, and enterprise risk management processes.
CMS Energy and Consumers continue to focus on opportunities to protect the environment and to reduce their carbon footprint. As a result of actions already taken, by CMS Energy and Consumers the companies have:
decreased their combined percentage of electric supply (self-generated and purchased) from coal by 1813 percentage points since 2015
reduced carbon dioxide emissions by over 3530 percent since 2005
reduced the amount of water used to generate electricity by 31nearly 30 percent since 2012
reduced landfill waste disposal by over 1.31.6 million tons since 1992
reduced methane emissions by 17nearly 20 percent since 2012
Additionally, over the last 20 years,
53

Since 2005, Consumers has reduced its sulfur dioxide nitrogen oxide,and particulate matter and mercury emissions by over 90 percent and its nitrogen oxide emissions by over 80 percent. Consumers began tracking mercury emissions in 2007; since that time, it has reduced such emissions by nearly 90 percent. Presented in the following illustration are Consumers’ reductions in these emissions (Consumers began tracking mercury emissions in 2007):emissions:
chart-historicairemissions.jpg

cms-20211231_g9.jpg
The 2016 Energy Law:
raised the renewable energy standard to 12.5 percent in 2019 and 15 percent in 2021; Consumers met the 12.5-percent15-percent requirement in 20192021 and expects to meet the requirement in future years with a combination of newly generated RECs and previously generated RECs carried over from prior years
established a goal of 35 percent combined renewable energy and energy waste reduction by 2025; Consumers has achieved 2230 percent of the combined renewable energy and energy waste reduction goal through 20192021
authorized incentives for demand response programs and expanded existing incentives for energy efficiency programs, referring to the combined initiatives as energy waste reduction programs
established an integrated planning process for new generationcapacity and energy resources
Consumers filed anConsumers’ Clean Energy Plan details its strategy to meet customers’ long-term energy needs. The Clean Energy Plan was originally outlined in Consumers’ 2018 IRP, withwhich was approved by the MPSC in June 2018, detailing its Clean Energy Plan. In March 2019, Consumers and a broad coalition of key stakeholders, including business customers, environmental groups, the MPSC Staff, and the Michigan Attorney General, filed an agreement settling the IRP with the MPSC and the MPSC approved it in June 2019.
Under its Clean Energy Plan, Consumers will meet the requirements of the 2016 Energy Law using its clean and lean strategy, which focuses on increasing the generation of renewable energy, helping customers use less energy, and offering demand response programs to reduce demand during critical peak times. Further,
54

In June 2021, Consumers filed its 2021 IRP with the MPSC, proposing updates to the Clean Energy Plan. Within its 2021 IRP, which is subject to MPSC approval, Consumers outlines its long-term strategy for delivering clean, reliable, resilient, and affordable energy to its customers, including plans to replace itsto:
end the use of coal-fueled generation predominantly within 2025, 15 years sooner than initially planned
purchase existing natural gas-fueled generating units, providing an additional 2,177 MW of nameplate capacity and allowing Consumers to continue providing controllable sources of electricity to customers
expand its investment in renewable energy, which willadding nearly 8,000 MW of solar generation by 2040
These steps are expected to enable Consumers to meet and exceed the 2016 Energy Law renewable energy requirements and fulfill increasing customer demand for renewable energy. Through its Clean Energy Plan, Consumers expectsThe 2021 IRP is also expected to reduce carbon emissions of its owned generation by more than 90 percent from its 2005 levels by 2040. Additionally, the plan will allow Consumers to achieve aexceed its breakthrough goal of at least 50 percent combined renewable energy and energy waste reduction by 2030.


53


achieving net-zero carbon emissions from its electric business by 2040. This goal includes not only emissions from Consumers’ owned generation, but also emissions from the generation of power purchased through long-term PPAs and from the MISO energy market. Consumers expects to meet 90 percent of its customers’ needs with clean energy sources by 2040 through execution of its 2021 IRP. Carbon offset measures including, but not limited to, carbon sequestration, methane emission capture, and forest preservation and reforestation may be used to close the gap to achieving net-zero carbon emissions.
Presented in the following illustration is Consumers’ 20192021 capacity portfolio and its future capacity portfolio as projected in the 2021 IRP. This illustration includes the effects of purchased capacity and energy waste reduction and uses the nameplate capacity of renewablefor all energy sources:

In 2020, Michigan’s Governor signed an executive order creating the Michigan Healthy Climate Plan, which outlines goals for Michigan to achieve economy-wide net-zero greenhouse gas emissions and to be carbon neutral by 2050. The executive order aims for a 28-percent reduction below 2005 levels of
55

greenhouse gas emissions by 2025. Consumers has already surpassed the 28-percent reduction milestone for its owned electric generation and previously announced a goal of achieving net-zero carbon emissions from its electric business by 2040.
In addition to Consumers’ efforts to reduce the electric utility’s carbon footprint, it is also making efforts to reduce the gas utility’s methane footprint. In October 2019, Consumers released its Methane Reduction Plan, which set a goal of net-zero methane emissions from its natural gas delivery system by 2030. Consumers’ Methane Reduction Plan, released in November 2019, outlines its plan to reach this net-zero emissions goal. Consumers plans to reduce methane emissions from its system by about 80 percent by accelerating the replacement of aging pipe, rehabilitating or retiring outdated infrastructure, and adopting new technologies and practices. The remaining emissions will be eliminatedoffset by purchasing and/or producing renewable natural gas.
In December 2021, Consumers announced plans to begin development of a renewable natural gas facility that will capture methane from manure generated at a neighboring farm and convert it into renewable natural gas. The facility, expected to start production in 2023, will reduce methane emissions from the dairy farm and allow Consumers to deliver renewable natural gas as a cost-effective clean alternative fuel for customers.
Additionally, to advance its environmental stewardship in Michigan and to minimize the impact of future regulations, Consumers announced the following five‑year targets during 2018:
to reduce its water use by one billion gallons; during 2018 and 2019,since 2017, Consumers reduced its water usage by over 400 million1.3 billion gallons cumulatively
to enhance, restore, or protect 5,000 acres of land; since 2017, Consumers enhanced, restored, or protected over 6,000 acres of land cumulatively
to reduce the amount of waste taken to landfills by 35 percent; during 2018 and 2019,compared to 2017, Consumers reduced its landfill waste to landfills by 1044 percent in 2021
to enhance, restore, or protect 5,000 acresConsumers exceeded each of land; during 2018these targets and 2019, Consumers enhanced, restored, or protected over 2,200 acres of land

In recent years, CMS Enterprises completed the development of and now operates a wind generation project and three solar generation projects.coming years.
CMS Energy and Consumers are monitoring numerous legislative, policy, and regulatory initiatives, including those to regulate greenhouse gases, and related litigation. While CMS Energy and Consumers cannot predict the outcome of these matters, which could have a material effect on the companies,affect them materially, they intend to continue to move forward with their clean and lean strategy.
Profit: The profit element of the triple bottom line represents CMS Energy’s and Consumers’ commitment to meeting their financial objectives and providing economic development opportunities and benefits in the communities in which they do business. CMS Energy’s and Consumers’ financial strength allows them to maintain solid investment-grade credit ratings and thereby reduce funding costs for the benefit of customers and investors, to preserve and create jobs, and to reinvest in the communities they serve.
In 2019,2021, CMS Energy’s net income available to common stockholders was $680$1,348 million, and diluted EPS were $2.39.$4.66. This compares with net income available to common stockholders of $657$755 million and diluted EPS of $2.32$2.64 in 2018.2020. In 2019, the benefits from electric and gas rate increases, higher gas sales due primarily to colder weather, cost control measures, and2021, the gain on the sale of transmission equipmentEnerBank, along with benefits from gas and electric rate increases and higher electric sales were offset partially by lower electric sales due primarily to unfavorable weather, higher depreciation and maintenance, higher service restoration costs, from 2019 storms, lower earnings at the enterprises segment,higher distribution, transmission, generation, and an accrual for a legacy legal obligation.compression expenses, and increased depreciation and property taxes, reflecting higher capital spending. A more detailed discussion of the factors affecting CMS Energy’s and Consumers’ performance can be found in the Results of Operations section that follows this Executive Overview.
Over the next five years, Consumers projects that itsexpects weather-normalized electric weather-normalized deliveries will decrease slightly and gas weather-normalized deliveries willto remain stable through 2024.relative to 2021. This outlook reflects the effects of energy waste reduction programs offset largely by modest growth in electric and gas demand.

CMS Energy and Consumers will continue to utilize the Consumers EnergyCE Way to enable them to achieve world class performance and positively impact the triple bottom line. Consumers’ investment plan and the regulatory environment in which it operates also drive its ability to impact the triple bottom line.
Investment Plan: Consumers expects to make capital investments of $25 billion over the next ten years. Over the next five years, Consumers expects to make significant expenditures on infrastructure upgrades


55


and replacements and electric supply projects. While it has a large number of potential investment opportunities that would add customer value, Consumers has prioritized its spending based on the criteria of enhancing public safety, increasing reliability, maintaining affordability for its customers, and advancing its environmental stewardship. Consumers’ investment program is expected to result in annual rate-base growth of six to eight percent. This rate-base growth, together with cost-control measures, should allow Consumers to maintain affordable customer prices.

The electric distribution projects comprise $4.4 billion to strengthen circuits and substations, replace poles, and replace poles.interconnect clean energy resources. Consumers also expects to spend $2.8 billion on new clean generation, which includes investments in wind, solar, and hydro electric generation resources, and $0.7 billion on other electric supply projects, primarily new renewable generation.projects.
Regulation: Regulatory matters are a key aspect of Consumers’ business, particularly rate cases and regulatory proceedings before the MPSC, which permit recovery of new investments while helping to ensure that customer rates are fair and affordable. Important regulatory events and developments not already discussed are summarized below.
2018
2021 Electric Rate Case:In December 2021, the MPSC approved an annual rate increase of $27 million, based on a 9.9 percent authorized return on equity that will be reflected in rates beginning January 1, 2022. In its order, the MPSC disallowed cost recovery for certain categories of recently completed capital expenditures incurred by Consumers. For additional details, see Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 2, Regulatory Matters.
2021 Gas Rate Case: In December 2021, Consumers filed an application with the MPSC seeking an annual rate increase of $278 million, based on a 10.5 percent authorized return on equity and a projected twelve-month period ending September 30, 2023. The filing requests authority to recover new In May 2018, Consumers filed an application with the MPSC seeking an annual rate increase of $58 million, based on a 10.75 percent authorized return on equity. In October 2018, Consumers reduced its requested annual rate increase to $44 million. In January 2019, the MPSC approved a settlement agreement authorizing an annual rate decrease of $24 million, based on a 10.0 percent authorized return on equity. With the elimination of the

The settlement agreement also provided for deferred accounting treatment for distribution-related capital investments exceeding certain amounts.allow Consumers also agreed to not file a new electric rate case prior to January 2020.improve system safety and reliability and reduce fugitive methane emissions.
2018 Gas Rate Case: In November 2018, Consumers filed an application with the MPSC seeking an annual rate increase of $229 million, based on a 10.75 percent authorized return on equity. In April 2019, Consumers reduced its requested annual rate increase to $204 million. In September 2019, the MPSC approved an annual rate increase of $144 million, based on a 9.9 percent authorized return on equity. This increase includes a $13 million adjustment to begin returning net regulatory tax liabilities associated with the TCJA to customers. The MPSC also approved the continuation of a revenue decoupling mechanism, which annually reconciles Consumers’ actual weather-normalized, non‑fuel revenues with the revenues approved by the MPSC.
2019 Gas Rate Case: In December 2019, Consumers filed an application with the MPSC seeking an annual rate increase of $245 million, based on a 10.5 percent authorized return on equity. The filing also seeks approval of a revenue decoupling mechanism that would annually reconcile Consumers’ actual weather-normalized non‑fuel revenues with the revenues approved by the MPSC.
Tax Cuts and Jobs Act: The TCJA, which changed existing federal tax law and included numerous provisions that affect businesses, was signed into law in December 2017. In October 2018, Consumers filed an application to address the December 31, 2017 remeasurement of its deferred income taxes and other base rate impacts of the TCJA on customers. In September 2019, the MPSC authorized Consumers to begin returning net regulatory tax liabilities of $0.4 billion to gas customers through rates approved in the 2018 gas rate case and $1.2 billion to electric customers through rates to be determined in Consumers’ next electric rate case. Until then, the MPSC authorized Consumers to refund $32 million to electric customers through a temporary bill credit. For details on these proceedings, see Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 3, Regulatory Matters.
Looking Forward
CMS Energy and Consumers will continue to consider the impact on the triple bottom line of people, planet, and profit in their daily operations as well as in their long-term strategic decisions. Consumers will continue to seek fair and timely regulatory treatment that will support its customer-driven investment plan, while pursuing cost-control measures that will allow it to maintain sustainable customer base rates. The Consumers EnergyCE Way is an important means of realizing CMS Energy’s and Consumers’ purpose of achieving world class performance while delivering hometown service.

Capital Resources and Liquidity
CMS Energy and Consumers expect to have sufficient liquidity to fund their present and future commitments. CMS Energy uses dividends and tax-sharing payments from its subsidiaries and external financing and capital transactions to invest in its utility and nonutility businesses, retire debt, pay dividends, and fund its other obligations. The ability of CMS Energy’s subsidiaries, including Consumers, to pay dividends to CMS Energy depends upon each subsidiary’s revenues, earnings, cash needs, and other factors. In addition, Consumers’ ability to pay dividends is restricted by certain terms included in its debt covenants and articles of incorporation and potentially by FERC requirements and provisions under the Federal Power Act and the Natural Gas Act. For additional details on Consumers’ dividend restrictions, see Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 5,4, Financings and Capitalization—Dividend Restrictions. ForDuring the year ended December 31, 2019,2021, Consumers paid $592$722 million in dividends on its common stock to CMS Energy.
As a result of a provision in the TCJA,On October 1, 2021, EnerBank was acquired by Regions Bank. CMS Energy is required to recover all alternative minimum tax creditsreceived proceeds of over four years through offsets of regular tax and through cash refunds.$1 billion. CMS Energy expectsintends to be ableuse the proceeds from the sale to offset regular tax primarily throughfund key initiatives in its core energy business related to safety, reliability, and its clean energy transformation. For information regarding EnerBank, see Item 8. Financial Statements and Supplementary Data—Notes to the use of federal net operating loss carryforwardsConsolidated Financial Statements—Note 20, Exit Activities and accordingly, receive alternative minimum tax credit refunds through 2021. Another provision in the TCJA excludes rate-regulated utilitiesDiscontinued Operations.
Consumers uses cash flows generated from 100 percent cost expensing of certain property. This provision will cause Consumers to make higher tax-sharing payments to CMS Energy, which in turn might permitoperations and external financing transactions, as well as stockholder contributions from CMS Energy, to maintain lower levels offund capital expenditures, retire debt, in order to invest in its businesses, pay dividends, and fund its generalother obligations. Consumers expectsalso uses these sources of funding to contribute to its employee benefit plans.
Financing and Capital Resources: CMS Energy and Consumers rely on the capital markets to fund their robust capital plan. Barring any sustained market dislocations or disruptions, CMS Energy and Consumers expect to continue to have sufficientready access to the financial and capital markets and will continue to explore possibilities to take advantage of market opportunities as they arise with respect to future funding sources availableneeds. If access to issue creditsthese markets were to customers for all impacts of the TCJA.diminish or otherwise become restricted, CMS Energy and Consumers would implement contingency plans to address debt maturities, which could include reduced capital spending.
In 2018,2020, CMS Energy entered into an equity offering program under which it may sell from time to time, shares of CMS Energyits common stock having an aggregate sales price of up to $250 million. Under this program, CMS Energy may sell its common stock$500 million in privately negotiated transactions, in “at the market” offerings, through forward sales transactions, or otherwise.
CMS Energy has entered into forward sales contracts having an aggregate sales price of $250 million. These contractstransactions under this program, which allow CMS Energy to either physically settle the contracts by issuing shares of its common stock at the then-applicable forward sale price specified by the agreement or net settle the contracts through the delivery or receipt of cash or shares. CMS Energy may settle the contracts at any time through their maturity dates, and presently intends to physically settle the contracts by delivering shares of its common stock. As of December 31, 2021, these contracts have an aggregate sales price of $56 million, maturing through 2022. For more information on thethese forward sale contracts, see Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 5,4, Financings and Capitalization—Issuance of Common Stock.
Consumers uses cash flows generated from operations and external financing transactions, as well as stockholder contributions from CMS Energy, to fund capital expenditures, retire debt, pay dividends, contribute to its employee benefit plans, and fund its other obligations. Accelerated pension funding in prior years and several initiatives to reduce costs have helped improve cash flows from operating activities.
Access to the financial and capital markets depends on CMS Energy’s and Consumers’ credit ratings and on market conditions. As evidenced by past financing transactions, CMS Energy and Consumers have had ready access to these markets. Barring major market dislocations or disruptions, CMS Energy and Consumers expect to continue to have ready access to the financial and capital markets. If access to these markets were to diminish or otherwise become restricted, CMS Energy and Consumers would implement contingency plans to address debt maturities, which could include reduced capital spending.
At December 31, 2019,2021, CMS Energy had $544$526 million of its revolving credit facility available and Consumers had $1.1 billion available under its revolving credit facilities. CMS Energy and Consumers use these credit facilities for general working capital purposes and to issue letters of credit. An additional source of liquidity is Consumers’ commercial paper program, which allows Consumers to issue, in one or


67


more placements, up to $500 million in the aggregate in commercial paper notes with maturities of up to
68

365 days at market interest rates. These issuances are supported by Consumers’ revolving credit facilities. While the amount of outstanding commercial paper does not reduce the available capacity of the revolving credit facilities, Consumers does not intend to issue commercial paper in an amount exceeding the available capacity of the facilities. At December 31, 2019,2021, there were $90 millionno commercial paper notes outstanding under this program. For additional details on CMS Energy’s and Consumers’ secured revolving credit facilities and commercial paper program, see Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 5,4, Financings and Capitalization.
Certain of CMS Energy’s and Consumers’ credit agreements debt indentures, and other facilities contain covenants that require CMS Energy and Consumers to maintain certain financial ratios, as defined therein. At December 31, 2019,2021, no default had occurred with respect to any financial covenants contained in CMS Energy’s and Consumers’ credit agreements, debt indentures, or other facilities.agreements. CMS Energy and Consumers were each in compliance with these covenants as of December 31, 2019,2021, as presented in the following table:

Material Cash Requirements: Based on the present investment plan, during 2022, Consumers projects capital expenditures of $2.6 billion. Additionally, CMS Energy’s other material cash requirements for 2022 include $2.3 billion of purchase obligations and $843 million of principal and interest payments on long-term debt. Consumers’ other material cash requirements for 2022 comprise $2.2 billion of purchase obligations and $653 million of principal and interest payments on long-term debt.
Components of CMS Energy’s and Consumers’ cash management plan include controlling operating expenses and capital expenditures and evaluating market conditions for financing and refinancing opportunities. CMS Energy’s and Consumers’ present level of cash and expected cash flows from operating activities, together with access to sources of liquidity, are anticipated to be sufficient to fund the companies’ contractual obligations and other material cash requirements for 20202022 and beyond.

Capital Expenditures: Over the next five years, Consumers expects to make substantial capital investments. Consumers may revise its forecast of capital expenditures periodically due to a number of factors, including environmental regulations, MPSC approval or disapproval, business opportunities, market volatility, economic trends, and the ability to access capital. Presented in the following table are Consumers’ estimated capital expenditures, including lease commitments, for 2022 through 2026:

Consumers Electric Utility Outlook and Uncertainties
Clean Energy Plan: While Consumers continuesConsumers’ Clean Energy Plan details its strategy to experience modest growthmeet customers’ long-term energy needs. The Clean Energy Plan was originally outlined in demand for electricity due to Michigan’s growing economy and increased use of air conditioning, consumer electronics, and other electric devices, it expects that increase in demand to be offsetConsumers’ 2018 IRP, which was approved by the effects of energy efficiency and conservation.
MPSC in 2019. In June 2018,2021, Consumers filed anits 2021 IRP with the MPSC, detailing itsproposing
70

updates to the Clean Energy Plan. Under its 2021 IRP, Consumers proposes to eliminate the use of coal-fueled generation in 2025 and expects to meet 90 percent of its customers’ needs with clean energy sources by 2040.
Specifically, the 2021 IRP provides for a full transition away from coal-fueled generation by the end of 2025 and includes:
the retirement of the D.E. Karn oil/gas-fueled and coal-fueled generating units, totaling 1,734 MW of nameplate capacity, in 2023
the retirement of the J.H. Campbell coal-fueled generating units, totaling 1,407 MW of nameplate capacity, in 2025
The MPSC has authorized Consumers to issue securitization bonds to finance the recovery of and return on the D.E. Karn coal-fueled generating units. In March 2019,the 2021 IRP, Consumers has requested regulatory asset treatment to recover the remaining book value of and a broad coalition of key stakeholders, including business customers, environmental groups,return on the MPSC Staff,other D.E. Karn units and the J.H. Campbell coal-fueled generating units.
To bridge the transition away from coal generation, the 2021 IRP proposes:
the purchase of the New Covert Generating Facility, a natural gas-fueled generating unit with 1,176 MW of nameplate capacity in Van Buren County, Michigan, Attorney General, filed an agreement settling in 2023
the purchase, in 2025, of the enterprises segment’s three natural gas-fueled generating units, totaling 1,001 MW of nameplate capacity:
the 770-MW DIG plant located in Dearborn, Michigan
a 156-MW peaking generating unit located in Gaylord, Michigan
a 75-MW peaking generating unit located in Comstock, Michigan
These investments are expected to allow Consumers to continue providing controllable sources of electricity to customers while expanding its investment in renewable energy. The 2021 IRP forecasts renewable energy capacity levels of 35 percent in 2025, 47 percent in 2030, and 63 percent in 2040, including the addition of nearly 8,000 MW of solar generation. Under its 2021 IRP, Consumers will continue to bid new capacity competitively. The updated plan proposes that Consumers will own and operate at least 50 percent of new capacity, with the MPSCremainder being built and owned by third parties.
Consumers’ Clean Energy Plan provides the MPSC approvedfoundation for its goal to achieve net-zero carbon emissions from its electric business by 2040. Under this net-zero goal, Consumers plans to eliminate the impact of carbon emissions created by the electricity it in June 2019.

generates or purchases for customers.
Through its Clean Energy Plan, Consumers expectscontinues to reduce carbon emissions ofmake progress on expanding its owned generation by more than 90 percent fromcustomer programs, namely its 2005 levels by 2040 and eliminate the use of coal to generate electricity by 2040. Specifically, the Clean Energy Plan provides for:
the retirement of the D.E. Karn 1 & 2 coal-fueled generating units, totaling 503 MW, in 2023
the continued assessment in future IRP filings concerning the retirement of the J.H. Campbell 1 & 2 coal-fueled generating units, totaling 609 MW, in 2025 or earlier
Under the Clean Energy Plan, Consumers will replace the capacity to be retired with:
increased demand response, programs
increased energy efficiency,
increased and conservation voltage reduction programs, as well as increasing its renewable energy generation
conservation voltage reduction
increasedand pumped storage generation.
Consumers will competitively bid new capacity and at least 50 percent of the new capacity will be built and owned by third parties; the remainder will be owned and operated by Consumers. In support of its Clean Energy Plan, Consumers issued a requestrequests for proposals in September 2019 and 2020, each to acquire up to 300 MW of new capacity from projects to be operational in Michigan’s Lower Peninsula by May 2022.2023. Specifically, Consumers solicited offers to enter into PPAs with or purchase solar generation projects ranging in size from 20 MW to 150 MW and to enter into PPAs with PURPA qualifying facilities up to 20 MW. Any contracts entered into as a result of the requests for proposals would be subject to MPSC approval.
71

As a result of the requests for proposals, Consumers has entered into PPAs to purchase renewable capacity, energy, and RECs from solar generating facilities and build transfer agreements to purchase solar generating facilities, as presented in the following table:

2    This agreement provides Consumers the option to purchase the associated solar generating facility after ten years.
In addition, Consumers issued a request for proposals in September 2021 to acquire up to 500 MW of new capacity from projects to be operational in Michigan’s Lower Peninsula by December 2024. Specifically, Consumers solicited offers to enter into PPAs with or purchase solar generation projects up to 300 MW in size and to enter into PPAs with PURPA qualifying facilities up to five MW in size. Consumers will acquire at least 250 MW through long-term PPAs. Any contracts entered into as a result of the request for proposals would be subject to MPSC approval.
As approved by the MPSC, the IRP allows Consumers to earn a financial incentive on PPAs approved by the MPSC after January 1, 2019. Additionally, the IRP allows for recovery of significant increases in demand response costs. The MPSC separately approved an associated financial incentive for exceeding certain demand response targets. Consumers is required to file a new IRP by June 2021.
PURPA: PURPA requires Consumers to purchase power from qualifying cogeneration and small power production facilities at a price approved by the MPSC that is meant to represent Consumers’ “avoided cost” of generating power or purchasing power from another source. In 2017, the MPSC issued an order establishing an avoided-cost methodology for determining the price that Consumers must pay to purchase power under PURPA. Among other things, the MPSC’s order changed the basis of Consumers’ avoided cost from the cost of coal-fueled generating units to that of natural gas-fueled generating units.
In order to address various complaints raised concerning the 2017 order, Consumers and various PURPA developers filed a settlement agreement with the MPSC in August 2019. Under the settlement agreement, which the MPSC approved in September 2019, Consumers will enter into contracts to purchase 584 MW of power from qualifying solar generation projects by September 2023. Of this amount, 170 MW will be purchased at the full avoided-cost rates set in the 2017 order. The remaining 414 MW will be purchased at a capacity payment equal to the MISO planning resource auction price and a designated energy price previously approved by the MPSC.
In the approved IRP settlement agreement, Consumers agreed to a new method of calculating avoided cost going forward, based on a competitive bidding process that will enable Consumers to purchase energy from new generation at competitive prices and mitigate the risk of forced purchases of unneeded or uneconomical renewable generation.
In September 2019, FERC issued a notice of proposed rulemaking that could result in modifications to the present federal regulations implementing PURPA. Among other things, the proposal would change the rules for measuring the size of qualifying facilities and determining whether certain PURPA projects have


71



access to wholesale markets. The proposal would also provide states with more flexibility to set the prices paid to PURPA projects. Consumers does not anticipate the proposed rulemaking will affect the PURPA projects with which it has agreements. Consumers cannot predict the outcome of this proposed rulemaking.
Renewable Energy Plan: The 2016 Energy Law raised the renewable energy standard to 15 percent in 2021, with an interim target of 12.5 percent in 2019.2021. Consumers is required to submit RECs, which represent proof that the associated electricity was generated from a renewable energy resource, in an amount equal to at least the required percentage of Consumers’ electric sales volume each year. Under its renewable energy plan, Consumers met the 15-percent requirement in 2021 and expects to meet its renewable energythe requirement each yearin future years with a combination of newly generated RECs and previously generated RECs carried over from prior years. Consumers met the interim target of 12.5 percent for 2019 and will demonstrate its compliance by filing the 2019 renewable energy cost reconciliation with the MPSC in June 2020.
In conjunction with itsUnder Consumers’ renewable energy plan, a third phase of Consumers’ Cross Winds® Energy Park, with nameplate capacity of 76 MW, began operations in December 2019. This project qualifies for certain federal production tax credits, generating cost savings that will be passed on to customers.
In February 2019, the MPSC issued an order ruling on amendments Consumers had requested to its renewable energy plan, andhas approved the acquisition of up to 525 MW of new wind generation projects. Under the renewable energy plan,projects and authorized Consumers is authorized to earn a 10.7 percent return on equity on any projects approved by the MPSC. AlsoSpecifically, the MPSC has approved the following:
purchase and construction of a 150-MW wind generation project in Gratiot County, Michigan; the project became operational in December 2020
purchase of a 166-MW wind generation project in Hillsdale, Michigan; the project became operational and Consumers took full ownership in February 2019, the MPSC approved an agreement under which Consumers purchased2021
72

purchase of a wind generation project under development, with capacity of up to 150201 MW, in Gratiot County, Michigan. Consumers began on-site construction of this project during the fourth quarter of 2019 and expects that it will be complete and operational in 2020.
In June 2019, Consumers entered into an agreement to purchase a wind generation project under development in Hillsdale, Michigan, with capacity of up to 166 MW. Under the agreement, which the MPSC unconditionally approved in December 2019,Michigan; Consumers expects to take full ownership and begin commercial operation of the project in 2020. Additionally, in September 2019,before 2024
The MPSC also approved the MPSC approvedexecution of a 20‑year agreement20-year PPA under which Consumers will purchase 100 MW of renewable capacity, energy, and RECs from a 149‑MW149-MW solar generating facility to be constructed in Calhoun County, Michigan. TheMichigan; the facility is expected to be operational in 2021. These agreements resulted from2022.
Voluntary Large Customer Renewable Energy Program: Consumers provides service under a program that provides large full-service electric customers with the opportunity to advance the development of renewable energy beyond the requirements of the 2016 Energy Law. In September 2021, the MPSC approved Consumers’ request for proposals that Consumers issued in June 2018 to acquireamend its renewable energy plan to remove the annual subscription limit associated with this program. The MPSC also approved up to 4001,000 MW of new wind generation projects and up to 100 MW of solar generation projects in Michigan.between 2024 and 2027 to meet customer demand for the program. Consumers will competitively solicit for additional renewable energy assets based on customer applications and will construct the assets based on customer subscriptions to the program.
Electric Customer Deliveries and Revenue: Consumers’ electric customer deliveries are seasonal and largely dependent on Michigan’s economy. The consumption of electric energy typically increases in the summer months, due primarily to the use of air conditioners and other cooling equipment. In addition, Consumers’ electric rates, which follow a seasonal rate design, are higher in the summer months than in the remaining months of the year. Beginning inIn June 2020,2021, electric residential customers will transitiontransitioned to a summer peak time-of-use rate that will allowallows them to take advantage of lower-cost energy during off-peak times during the summer months. Thus, customers couldcan reduce their electric bills by shifting their consumption from on-peakon‑peak to off-peakoff‑peak times.

In response to the COVID‑19 pandemic, Michigan’s Governor and the Michigan Department of Health and Human Services have issued numerous orders throughout 2020 and 2021 restricting business, educational, and personal activities at varying levels. In June 2021, almost all restrictions were lifted and Consumers expects businesses and residents to continue resuming normal activities and for weather-normalized electric deliveries to stabilize.

72



Over the next five years, Consumers expects weather-normalized electric deliveries over the next five years to decrease slightly.remain stable relative to 2021. This outlook reflects the effects of energy waste reduction programs and appliance efficiency standards offset largely by modest growth in electric demand. Actual delivery levels will depend on:
energy conservation measures and results of energy waste reduction programs
weather fluctuations
Michigan’s economic conditions, including utilization, expansion, or contraction of manufacturing facilities, population trends, and housing activity
Electric ROA: Michigan law allows electric customers in Consumers’ service territory to buy electric generation service from alternative electric suppliers in an aggregate amount capped at ten percent of Consumers’ sales, with certain exceptions. At December 31, 2019,2021, electric deliveries under the ROA program were at the ten‑percent limit. Of Consumers’ 1.81.9 million electric customers, 285 customers,fewer than 300, or 0.02 percent, purchased electric generation service under the ROA program.
The 2016 Energy Law established a path to ensure that forward capacity is secured for all electric customers in Michigan, including customers served by alternative electric suppliers under ROA. The new law also authorized the MPSC to ensure that alternative electric suppliers have procured enough capacity to cover their anticipated capacity requirements for the four-year forward period. In 2017, the MPSC issued an order establishing a state reliability mechanism for Consumers. Under this mechanism, beginning June 1, 2018, if an alternative
73

electric supplier does not demonstrate that it has procured its capacity requirements for the four-year forward period, its customers will pay a set charge to the utility for capacity that is not provided by the alternative electric supplier. All alternative electric suppliers have demonstrated that they have procured their capacity requirements through the MISO planning year beginning June 1, 2022.2024.
In June 2018,During 2017, the MPSC issued an order requiringorders finding that it has statutory authority to determine and implement a local clearing requirement, which requires all electric suppliers to demonstrate that a portion of the capacity procured to serve customers during peak demand times is located in the MISO footprint in Michigan’s Lower Peninsula. In July 2018,April 2020, the Michigan Supreme Court of Appeals issued a decision thataffirmed the MPSC does not haveMPSC’s statutory authority to implement such a local clearing requirement for alternativeon individual electric suppliers. Consumers believesproviders.
In September 2020, ABATE and another intervenor filed a complaint against the 2016 Energy Law does give such authorization to the MPSC. The MPSC and Consumers have filed applications for leave to appeal the Court of Appeals’ decision to the Michigan Supreme Court. In June 2019, the Michigan Supreme Court issued orders directing the filing of supplemental briefs and the scheduling of oral arguments in the U.S. District Court for the Eastern District of Michigan challenging the constitutionality of a local clearing requirement. The complaint requests the federal court to issue a permanent injunction prohibiting the MPSC from implementing a local clearing requirement on individual electric providers. In December 2020, Consumers filed a motion to intervene and defend the local clearing requirement in that federal litigation; this motion was granted in January 2021 and this case and will ultimately decide whether to consider and rule on the appeals. Oral arguments occurred in November 2019, and the Michigan Supreme Court will issue an order on the application for leave to appeal.remains pending.
Electric Rate Matters: Rate matters are critical to Consumers’ electric utility business. For additional details on rate matters, see Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 2, Regulatory Matters and Note 3, Contingencies and Commitments.
2021 Electric Rate Case: In December 2021, the MPSC approved an annual rate increase of $27 million, based on a 9.9 percent authorized return on equity that will be reflected in rates beginning January 1, 2022. In its order, the MPSC disallowed cost recovery for certain categories of recently completed capital expenditures incurred by Consumers. For additional details, see Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 2, Regulatory Matters.
Depreciation Rate Case: In March 2021, Consumers filed a depreciation case related to its electric and common utility property. In this case, Consumers requested to increase depreciation expense, and its recovery of that expense by $43 million annually. In December 2021, the MPSC approved a settlement agreement that decreases depreciation expense by $27 million annually based on December 31, 2019 balances. The new depreciation rates will be reflected in rates beginning January 1, 2022, concurrent with rates to be implemented in accordance with Consumers’ recently approved electric rate case.
PSCR Plan: Consumers submitted its 20202022 PSCR plan to the MPSC in September 20192021 and, in accordance with its proposed plan, self-implemented the 20202022 PSCR charge beginning in January 2020.2022.
Retention Incentive Program: In 2019, Consumers announced a retention incentive program to ensure necessary staffing at the D.E. Karn generating complex through the anticipated retirement of the coal-fueled generating units. Based on the number of employees that have chosen to participate, the aggregate cost of the program through 2023 is estimated to be $35 million. In its order in Consumers’ 2020 electric rate case, the MPSC approved deferred accounting treatment for these costs. Consumers expects to recognize $5 million of retention benefit costs in 2022; this expense will be deferred as a regulatory asset. For additional details on this program, see Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 20, Exit Activities and Discontinued Operations. Within its 2021 IRP, Consumers proposes to retire the J.H. Campbell coal-fueled generating units. No retention incentive costs related to this retirement will be recognized unless Consumers’ 2021 IRP is approved by the MPSC.

Electric Environmental Outlook: Consumers’ operations are subject to various state and federal environmental laws and regulations. Consumers estimates that it will incur capital expenditures of $275$255 million from 20202022 through 20242026 to continue to comply with RCRA, the Clean Water Act, the Clean Air Act, and numerous state and federal environmental regulations. Consumers expects to recover these costs in customer rates, but cannot guarantee this result. Consumers’ primary environmental compliance focus includes, but is not limited to, the following matters.


73



Air Quality: Multiple air quality regulations apply, or may apply, to Consumers.
CSAPR, which initially became effective in 2015, requires Michigan and many other states to improve air quality by reducing power plant emissions that, according to EPA computer models,modeling, contribute to ground-level ozone and fine particle pollution in other downwind states. In 2016, the EPA finalized new ozone season standards for CSAPR, which became effective in 2017. AnyIn 2020, in response to a court-ordered remand due to litigation, or remand to the EPA is not expectedproposed a revised CSAPR rule to impact Consumers’reflect updated emission reductions from electric generating units in 12 states, including Michigan. The EPA finalized this revised rule in March 2021, with continued emission reductions through 2024. Consumers has evaluated its emission compliance strategy as Consumers expects its emissionsfor existing units based on the proposed number of allowances allocated to Michigan for 2021 through 2024 and believes the impact of this rule should be within the CSAPR allowance allocations.minimal.
In 2012, the EPA published emission standards for electric generating units, known as MATS, based on Section 112 of the Clean Air Act. Under MATS, all of Consumers’ existing coal-fueled electric generating units were required to add additional controls for hazardous air pollutants. Consumers met the extended deadline of April 2016 for five coal-fueled units and two oil/gas-fueled units it continues to operate and retired its seven remaining coal-fueled units. MATS is presently being litigated. In addition, in December 2018,May 2020, the EPA proposedfinalized changes to the supporting analysis used to justifyenact the MATS but didrule. However, in January 2022, the EPA announced a proposed rule to revoke this 2020 finding and reaffirm that it is appropriate and necessary to regulate emissions of hazardous air pollutants from coal- and oil-fueled power plants. The EPA is also considering whether more stringent protections for hazardous air pollution from power plants are feasible and warranted. Consumers will continue to monitor the MATS rule status and any pending litigation. Consumers does not proposeexpect any changes to the MATS regulations. Any changes resulting from litigation or rulemaking are expected to be minor and should notrule will have a significant impact Consumers’on its current MATS compliance strategy. If the MATS regulations were repealed, Consumers would then be required to comply with the Michigan Mercury Rule, which has similar requirements to MATS. In addition, Consumers must comply with its settlement agreement with the EPA entered into in 2014 concerning opacity and NSR, which has similar emission requirements to MATS.
In 2015, the EPA lowered the NAAQS for ozone. The new2015 ozone NAAQS will makemade it more difficult to construct or modify power plants and other emission sources in areas of the country that have not met the new2015 ozone standard. In April 2018, the EPA designated certain areas of Michigan as not meeting the newozone standard. Specifically, seven counties in southeastern Michigan and three counties in western Michigan were not in attainment with the ozone standard withby an August 2018 effective date. 2021 regulatory deadline, and thus may have their nonattainment designations increased from marginal to moderate. None of Consumers’ fossil-fuel-fired generating units are located in these areas. SomeThe State of Consumers’ compressor stations are locatedMichigan has convened industry workgroups to seek implementation and control strategy ideas for statewide compliance of the 2015 ozone standard, which will need to be in place by early 2023. In January 2022, EGLE submitted a request to the EPA for redesignation of the seven counties in southeastern Michigan to be in attainment with the 2015 ozone standard based on the most recent data. EGLE is awaiting the EPA’s response to that request. Consumers will continue to stay engaged with EGLE and the workgroups to assess potential impacts to its generating assets.
In August 2020, the EPA proposed to retain the 2015 NAAQS for ozone without revision and finalized this regulatory decision in December 2020. In October 2021, the EPA provided notice that it was going to reconsider the December 2020 ozone NAAQS decision. The EPA believes it will complete this reconsideration by December 2023. Although this action may ultimately result in more ozone nonattainment areas impacted by the rule, but Consumers expects only minor permitting impacts if those units are modified in the future.Michigan, Consumers does not expect that any litigation involving NAAQS for ozone or lowering of the ozone standard will have a material adverse impact on its generating assets.
75

Consumers’ strategy to comply with air quality regulations, including CSAPR, NAAQS,MATS, and MATS,NAAQS, as well as its legal obligations, involved the installation and operation of emission control equipment at some facilities and the suspension of operations at others; however, Consumers continues to evaluate these rules in conjunction with other EPA and EGLE rulemakings, litigation, executive orders, treaties, and congressional action. This evaluation could result in:
a change in Consumers’ fuel mix
changes in the types of generating units Consumers may purchase or build in the future
changes in how certain units are usedoperated
the retirement, mothballing, or repowering with an alternative fuel of some of Consumers’ generating units
changes in Consumers’ environmental compliance costs
Greenhouse Gases: There have been numerous legislative and regulatory initiatives at the state, regional, national, and international levels that involve the potential regulation of greenhouse gases. Consumers continues to monitor and comment on these initiatives and to follow litigation involving greenhouse gases.
In 2015, the EPA finalized new rules pursuant to Section 111(b) of the Clean Air Act to limit carbon dioxide emissions from new electric generating units, as well as modified or reconstructed electric


74



generating units. New coal-fueled units would not be able to meet this limit without installing carbon dioxide control equipment using such methods as carbon capture and sequestration.
In December 2018, the EPA proposed a revised Section 111(b) regulation to replace the 2015 standard rule limiting carbon dioxide emissions from new electric generating units, citing limited availability and high costs of carbon capture and sequestration equipment as reasons to change the 2015 rule. The revised Section 111(b) regulation requireswould require new coal-fueled generating units to meet a highly efficient steam cycle performance standard. If finalized, Consumers does not expect this proposal to change its existing environmental strategy. The EPA has not formally indicated whether they intend to finalize this rulemaking or instead pursue a new set of regulations.
In June 2019, the EPA finalized the Affordable Clean Energy rule. The rule, requireswhich required individual states to evaluate coal‑fueled power plants for heat‑rate improvements that could increase overall plant efficiency. The evaluationsIn January 2021, the D.C. Circuit Court of Appeals vacated and remanded this rule to be performedthe EPA which, in turn, appealed the rule to the U.S. Supreme Court. In October 2021, the U.S. Supreme Court agreed to hear an appeal of this case. A decision is expected by the State of Michigan under the final rule may require Consumers to make heat-rate improvements at its remaining coal-fueled units beginning in the mid‑2020s. This rule is presently being litigated.June 2022. Consumers cannot evaluate the potential impact of the rule until any appeals and EPA actions are resolved. It is anticipated that the StateEPA will propose a new regulation in 2022 addressing greenhouse gas emissions from existing fossil-fueled electric generating units, potentially under the Clean Air Act; however, Consumers cannot predict the form and extent of Michigan completes its evaluations.such potential regulation as it is likely to be impacted by the U.S. Supreme Court’s decision on the Affordable Clean Energy rule.
In 2015, a group of 195 countries, including the U.S., finalized the Paris Agreement, which governsaddresses carbon dioxide reduction measures beginning in 2020. AlthoughWhile the U.S. has begun the process of withdrawinghad withdrawn from the Paris Agreement, it has statedrejoined the Paris Agreement in 2021. In April 2021, the U.S. announced it is committing to a desirenationally determined contribution under the Paris Agreement. Nationally determined contributions are the efforts by each country to renegotiatereduce national greenhouse gas emissions. The commitment made by the U.S. is to reduce greenhouse gas emissions by 50 to 52 percent from 2005 levels by 2030. In its 2021 IRP, pending MPSC approval, Consumers proposed a new agreement60-percent reduction in the future.its carbon emissions from 2005 levels by 2025. At this time, Consumers does not expect any adverse changes to its environmental strategy as a result of these events, as the nationally determined contribution is not binding without new Congressional legislation.
76

In 2020, Michigan’s Governor signed an executive order creating the Michigan Healthy Climate Plan, which outlines goals for Michigan to achieve economy-wide net-zero greenhouse gas emissions and to be carbon neutral by 2050. The executive order aims for a 28-percent reduction below 2005 levels of greenhouse gas emissions by 2025. Consumers has already surpassed the 28-percent reduction milestone for its owned electric generation and previously announced a goal of achieving net-zero carbon emissions from its electric business by 2040. The order directs EGLE to develop and oversee an action plan for achieving these goals. In addition, the Governor established the Council on Climate Solutions, an advisory group of key stakeholders to be appointed by the Governor that will assist EGLE in implementing the plan. These goals are aspirational in nature and any changes in law or regulation to achieve these goals would need to be approved by Michigan Legislature or the relevant regulatory agency. The MPSC has requested comments from utilities and other stakeholders on how the Governor’s goal should be incorporated into future IRP filings. Consumers does not expect any adverse changes to its environmental strategy as a result of these events.
While Consumers cannot predict the outcome of changes in U.S. policy or of other legislative or regulatory initiatives involving the potential regulation of greenhouse gases, it intends to continue to move forward with its Clean Energy Plan, its present net-zero carbon reduction goal, and its emphasis on supply diversity.reliable and resilient supply. Consumers will continue to monitor regulatory and legislative activity and related litigation regarding greenhouse gas emissions standards that may affect electric generating units.
SevereIncreased frequency of severe weather events, andincluding those due to climate change, associated with increasing levels of greenhouse gases could affectmaterially impact Consumers’ facilities, and energy sales, and could have a material impact on its future results of operations. Consumers is unable to predict these events or their financial impact; however, Consumers plans for adverse weatherevaluates the potential physical impacts of climate change on its operations, including increased temperature, increased storm activity, increased rainfall, and takeshigher lake and river levels. Consumers is taking steps to reduce its potential impact.mitigate these risks as appropriate.

Consumers may be required to replace equipment,equipment; install additional emission control equipment,equipment; purchase emission allowances or credits,credits; curtail operations,operations; arrange for alternative sources of supply,supply; purchase facilities that generate fewer emissions; mothball or retire facilities that generate certain emissions,emissions; pursue energy efficiency or demand response measures more swiftly,swiftly; or take other steps to manage or lower the emission of greenhouse gases. Although associated capital or operating costs relating to greenhouse gas regulation or legislation could be material and cost recovery cannot be assured, Consumers expects to recover these costs and capital expenditures in rates consistent with the recovery of other reasonable costs of complying with environmental laws and regulations.
CCRs: In 2015, the EPA published a final rule regulating CCRs under RCRA. The finalThis 2015 rule adopts minimum standards for beneficially reusing and disposing of non‑hazardous CCRs. The rule establishes new minimum requirements for siteCCR unit location, design, structural stability, groundwater monitoring and correction action, flood protection, storm water design, fugitive dust control, recordkeeping, and public disclosure of information,certain records, including any groundwater protection standard exceedances. The 2015 rule also sets out conditions under which some CCR units would be forced to cease receiving CCR and non‑CCR wastewater and initiate closure based on the inability to achieve minimum safety standards, meet a location standard, or meet minimum groundwater standards. Consumers has aligned with EGLE on closure plans for each of its unlined ash ponds to ensure coordination between federal and state requirements. The unlined ash ponds have ceased operation and have been replaced with


75



double-lined ash ponds or concrete tanks. Significant closure work has been completed at the remaining ash ponds.
Due to litigation, many aspects of the 2015 CCR rule have been remanded to the EPA, which has resulted in various new rulemakings. These new rulemakings are nownumerous proposed rules and three final rules. One of the final rules is in litigation. ContinuedAnticipated litigation related to remanded aspects that have not been addressed will add uncertainty around requirements for compliance and state permit programs.
Separately,The EPA amended the conditions of forced closure in a rule published in August 2020. The August 2020 rule required all unlined CCR units to initiate closure by mid-April 2021, unless conditions that satisfied an alternate closure schedule were approved by the EPA. Consumers, with agreement from EGLE,
77

completed the work necessary to initiate closure by excavating CCRs or placing a final cover over each of its relevant CCR units prior to the April 2021 closure initiation deadline.
Separate from the 2015 or 2020 rules, Congress passed legislation in 2016 allowing participating states to develop permitting programs for CCRs under RCRA.RCRA Subtitle D. In December 2018, the Michigan Legislature adopted standards for a permitting program, which requires the EPA’s authorization. This program should reduce costly, duplicative oversight over CCRs and provide local oversight to CCR issues unique to Michigan. In April 2020, EGLE submitted the state CCRa regulatory package for Michigan’s permit program application to Michigan’s Attorney General in June 2019the EPA for its review, and signature. The Attorney General’s officewhich is engaged in a detailed review of the program and application with EGLE.still pending. Federal rulemaking challenges may delay EPA approval of the Michigan permitting program.
Consumers has aligned with EGLE on closure plans for all of its coal ash disposal sites, including those subject to the EPA’s 2015 CCR rule, and adjusted its recorded ARO accordingly. Consumers has historically been authorized to recover in electric rates costs related to coal ash disposal sites.
Water: Multiple water-related regulations apply, or may apply, to Consumers.
The EPA regulates cooling water intake systems of existing electric generating plants under Section 316(b) of the Clean Water Act and the corresponding rules that were revised in 2014. The rules are aimed at reducingseek to reduce alleged harmful impacts on aquatic organisms, such as fish. In April 2018, Consumers submitted to EGLE for review and approval all required studies and recommended plans to comply with Section 316(b), but has not yet received final approval.
In 2015, the EPA released its final effluent limitation guidelines for steam electric generating plants. These guidelines, which are presently being litigated, set stringent new requirements for the discharge from electric generating units into surface waters. The EPA published a final rule in October 2020, with an effective date of December 2020, revising the 2015 guidelines related to the discharge of certain wastewater streams. In 2017, the EPA announced that it will undertake a rulemaking to replace specific portionsstreams from electric generating units. The rule also allows for extension of the rule and proposed delayingcompliance deadline from the compliance start datesend of 2023 to the end of 2025, upon approval by EGLE through the NPDES permitting process. Consumers received such an extension to 2025 for two years, but maintained the compliance end dates. Additional rulemaking beganits Campbell generating facility in November 2019 and will continue in 2020.2021. Consumers does not expect any adverse changes to its environmental strategy as a result of anythese revisions to the rule.rule or any litigation of the guidelines.
In recent years,January 2020, the EPA and the U.S. Army Corps of Engineers have proposed rules redefining “Waters of the United States,” which defines the scope of federal jurisdictionfinalized a rule under the Clean Water Act and other changes to the Clean Water Act regulations. For example, the EPA recently finalizedthat repealed a rule repealing the 2015 definition of “Waters of the United States” and, in January 2020, released a rule with its new definition. These rules are presently being, or are likely to be, litigated.
A final definition would changeStates,” narrowed the scope of waterfederal jurisdiction, and wetlands regulations underreduced the Clean Water Act. The EPA has delegatedfrequency of dual jurisdiction in states with authority to manageregulate the same waters; Michigan wetlands program to EGLE for a large portion of Consumers’ service territory, but dual jurisdiction exists betweenis one such state. In November 2021, the EPA and the U.S. Army Corps of Engineers in some locations in Michigan. As a result, regardlessproposed to revise the 2020 “Waters of the ultimate outcomeUnited States” definition to revert to the 2015 “Waters of the United States” definition, with changes reflecting the EPA’s rules,interpretation of intervening U.S. Supreme Court decisions. The proposed November 2021 rulemaking may change how Consumers expectsinteracts with federal jurisdictional waters within Michigan, which may add additional requirements to continue to operate under Michigan’s wetlands regulations, and under the applicable state and federal water jurisdictional regulations. Thus,existing compliance programs, or may require additional permitting for infrastructure projects. However, Consumers does not expect any material adverse changes to its environmental strategy as a result of these events, but under an expanded federalthe current interpretations. The “Waters of the United States” definition could experience permitting delays for infrastructure projects where dual jurisdiction exists.

continues to be litigated in multiple jurisdictions.
Many of Consumers’ facilities maintain NPDES permits, which are renewed every five years and are vital to the facilities’ operations. Failure of EGLE to renew any NPDES permit, a successful appeal against a permit, a change in the interpretation or scope of NPDES permitting, or onerous terms contained in a permit could have a significant detrimental effect on the operations of a facility.
78

Protected Wildlife: Multiple regulations apply, or may apply, to Consumers relating to protected species and habitats.
Statutes like the Endangered Species Act, the Migratory Bird Treaty Act, and the Bald and Golden Eagle Protection Act may impact operations at Consumers’ facilities. In May 2021, the U.S. Fish and Wildlife Service proposed to repeal a January 2021 rule related to incidental take of migratory birds. In November 2021, the U.S. Fish and Wildlife Service published an advanced notice of proposed rulemaking outlining its intent to regulate incidental take under the Migratory Bird Treaty Act. Permitting and monitoring fees and restrictions on operations associated with the rules could impact Consumers’ existing and future operations, including wind and solar generation facilities.
Additionally, Consumers is monitoring proposed changes to the listing status of several species within its operational area due to an increase in wildlife-related regulatory activity. A change in species listed under the Endangered Species Act may impact Consumers’ costs to mitigate its impact on protected species and habitats at certain existing facilities as well as siting choices for new facilities.
Other Matters: Other electric environmental matters could have a material impact on Consumers’ outlook. For additional details on other electric environmental matters, see Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 4,3, Contingencies and Commitments—Consumers Electric Utility Contingencies—Electric Environmental Matters.
Retention Incentive Program: In October 2019, Consumers announced a retention incentive program to ensure necessary staffing at the D.E. Karn generating complex through the anticipated retirement of the coal-fueled electric generating units. Based on the number of employees that have chosen to participate, the aggregate cost of the program through 2023 is estimated to be $35 million. Consumers expects to recognize $15 million of expense related to retention and severance benefits in 2020. Consumers will seek recovery of these costs from customers. For additional details on this program, see Note 22, Asset Sales and Exit Activities.
Consumers Gas Utility Outlook and Uncertainties
Gas Deliveries: Consumers’ gas customer deliveries are seasonal. The peak demand for natural gas typically occurs in the winter due to colder temperatures and the resulting use of natural gas as heating fuel.
Over the next five years, Consumers expects weather-normalized gas deliveries over the next five years to remain stable relative to 2019.2021. This outlook reflects the effects of energy waste reduction programs offset largely by modest growth in gas demand offset by the predicted effects of energy efficiency and conservation.demand. Actual delivery levels from year to year may vary from this expectation as a result of:will depend on:
weather fluctuations

The filing also seeks approval of a revenue decoupling mechanism that would annually reconcile Consumers’ actual weather-normalized non‑fuelnon-fuel revenues with the revenues approved by the MPSC.
Depreciation Rate Case: In December 2021, Consumers filed a depreciation case related to its gas utility plant property. In this case, Consumers requested a decrease in depreciation expense of $1 million annually based on December 31, 2020 balances.
GCR Plan:Consumers submitted its 2020-20212022-2023 GCR plan to the MPSC in December 20192021 and, in accordance with its proposed plan, expects to self-implement the 2020-20212022-2023 GCR charge beginning in April 2020.2022.
Gas Pipeline and Storage Integrity and Safety: In October 2019,The PHMSA has published a final rulevarious rules that expandsexpand federal safety standards for gas transmission pipelines.pipelines and underground storage facilities. To comply with the rule,these rules, Consumers will incur increased capital and operating and maintenance costs to install and remediate pipelines as well as increased operating and maintenance costs to expand inspections, maintenance, and monitoring of its existing pipelines.pipelines and storage facilities. The initial requirements in the regulation taketook effect in July 1, 2020, with various implementationfuture regulation phases to be released over numerous years.
In 2016, PHMSA published an interim final rule that established minimum federal safety standards for underground natural gas storage facilities. To comply with the interim rule, Consumers incurred increased capital and operating and maintenance costs to expand inspections, maintenance, and monitoring of its underground gas storage facilities. PHMSA expects to finalize additional requirements in early 2020.
Although associated capital or operating and maintenance costs relating to these regulations could be material and cost recovery cannot be assured, Consumers expects to recover such costs and capital expenditures in rates consistent with the recovery of other reasonable costs of complying with laws and regulations. Consumers will continue to monitor gas safety regulations and is implementingcontinue implementation of the American Petroleum Institute’s Recommended Practice 1173, Pipeline Safety Management Systems. This program ensuresminimizes gas system asset- and performance-related risks by ensuring that there are policies, procedures, work instructions, forms, and records in place to streamline adoption and deployment of any existing or future regulations.
Gas Environmental Outlook: Consumers expects to incur response activity costs at a number of sites, including 23 former MGP sites. For additional details, see Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 4,3, Contingencies and Commitments—Consumers Gas Utility Contingencies—Gas Environmental Matters.
Air Quality: In 2015, the EPA lowered the NAAQS for ozone. The 2015 ozone NAAQS made it more difficult to construct or modify power plants and other emission sources in areas of the country that have not met the 2015 ozone standard. In 2018, the EPA designated certain areas of Michigan as not meeting the ozone standard. Specifically, seven counties in southeastern Michigan and three counties in western Michigan were not in attainment with the ozone standard by an August 2021 regulatory deadline, and thus may have their nonattainment designations increased from marginal to moderate. Some of Consumers’ compressor stations are located in these areas. The State of Michigan has convened industry workgroups
80

to seek implementation and control strategy ideas for statewide compliance of the 2015 ozone standard, which will need to be in place by early 2023. In January 2022, EGLE submitted a request to the EPA for redesignation of the seven counties in southeastern Michigan to be in attainment with the 2015 ozone standard based on the most recent data. EGLE is awaiting the EPA’s response to that request.
In August 2020, the EPA proposed to retain the 2015 NAAQS for ozone without revision and finalized this regulatory decision in December 2020. In October 2021, the EPA provided notice that it was going to reconsider the December 2020 ozone NAAQS decision. The EPA believes it will complete this reconsideration by December 2023. Consumers will continue to stay engaged with EGLE and the workgroups to assess potential impacts to its compressor stations.
Greenhouse Gases: Consumers is making voluntary efforts to reduce its gas utility’s methane emissions. In October 2019, Consumers released its Methane Reduction Plan, which set a goal of net-zero methane emissions from its natural gas delivery system by 2030. Under its Methane Reduction Plan, Consumers plans to reduce methane emissions from its system by about 80 percent by accelerating the replacement of aging pipe, rehabilitating or retiring


78



outdated infrastructure, and adopting new technologies and practices. The remaining emissions will be eliminatedoffset by purchasing and/or producing renewable natural gas.
In November 2021, the EPA released a proposed rule to regulate methane for the oil and gas sector. This proposed rule is not expected to have a material adverse impact on Consumers’ natural gas storage, compressor stations, and distribution systems, as it applies upstream of Consumers’ facilities.
In 2020, Michigan’s Governor signed an executive order creating the Michigan Healthy Climate Plan, which outlines goals for Michigan to achieve economy-wide net-zero greenhouse gas emissions and to be carbon neutral by 2050. The executive order aims for a 28-percent reduction below 2005 levels of greenhouse gas emissions by 2025. These new goals could impact Consumers’ gas business over the long term. Consumers is evaluating decarbonization options for its gas business including energy efficiency, renewable natural gas, carbon offsets, and other decarbonization methods. As one strategy, Consumers recently requested the MPSC’s approval of a proposed program that would allow gas customers to purchase carbon offset credits on a voluntary basis. Similarly, in December 2021, Consumers announced plans to begin development of a renewable natural gas facility that will capture methane from manure generated at a neighboring farm and convert it into renewable natural gas. For additional details on the executive order, see Consumers Electric Utility Outlook and Uncertainties—Electric Environmental Outlook.
In 2015, a group of 195 countries, including the U.S., finalized the Paris Agreement, which addresses carbon dioxide reduction measures beginning in 2020. While the U.S. had withdrawn from the Paris Agreement, it rejoined the Paris Agreement in 2021. In April 2021, the U.S. announced it is committing to a nationally determined contribution under the Paris Agreement. Nationally determined contributions are the efforts by each country to reduce national greenhouse gas emissions. The commitment made by the U.S. is to reduce greenhouse gas emissions by 50 to 52 percent from 2005 levels by 2030. In its 2021 IRP, pending MPSC approval, Consumers proposed a 60-percent reduction in its carbon emissions from 2005 levels by 2025. At this time, Consumers does not expect any adverse changes to its environmental strategy as a result of these events, as the nationally determined contribution is not binding without new Congressional legislation.
There is also increasing interest at the federal, state, and local levels involving potential regulation of greenhouse gases or its sources, which include methane emissions and carbon dioxide from Consumers’ gas utility.sources. Such regulation, if adopted, may involve requirements to reduce methane emissions from Consumers’ gas utility operations and carbon dioxide emissions from natural gas customer use. No such measures apply to Consumers at this time. Consumers continues to monitor these initiatives and comment as appropriate. Consumers cannot predict the impact of any potential future legislation or regulation on its gas utility.

Under its energy waste reduction plan, Consumers provides its customers with incentives to reduce usage by offering energy audits,audits; rebates and discounts on purchases of highly efficient appliances,appliances; and other incentives and programs.
Enterprises Outlook and Uncertainties
CMS Energy’s primary focus with respect to its enterprises businesses is to maximize the value of generating assets, its share of which represents 1,2341,483 MW of capacity, and to pursue opportunities for the development of renewable generation projects.
In June 2021, DIG, CMS Generation Michigan Power, and CMS ERM entered into an agreement with Consumers to sell, for $515 million, subject to certain adjustments, the enterprises segment’s three natural gas-fueled generating units, totaling 1,001 MW of nameplate capacity:
the 770-MW DIG plant located in Dearborn, Michigan
a 156-MW peaking generating unit located in Gaylord, Michigan
a 75-MW peaking generating unit located in Comstock, Michigan
The parties plan to close the sale, which is dependent upon regulatory approvals, in 2025.
The enterprises segment’s assets may be affected by environmental laws and regulations. The new2015 ozone NAAQS will makemade it more difficult to construct or modify power plants and other emission sources in areas of the country that have not met the new2015 ozone standard. In April 2018, the EPA designated certain areas of Michigan as not meeting the new standard with an August 2018 effective date. ozone standard. The enterprises segment’s DIG plant located in Dearborn, Michigan is in one such area and, as a result, would be subject to additional permitting restrictions in the event of any future modifications. For additional details regarding the new ozone NAAQS, see Consumers Electric Utility Outlook and Uncertainties—Electric Environmental Outlook.
Trends, uncertainties, and other matters related to the enterprises segment that could have a material impact on CMS Energy’s consolidated income, cash flows, or financial position include:

EnerBank Outlook and Uncertainties
EnerBank is a Utah state-chartered, FDIC-insured industrial bank providing unsecured consumer installment loans, largely for financing home improvements. The carrying value of EnerBank’s loan portfolio was $2.5 billion at December 31, 2019. The 12-month rolling average net default rate on loans held by EnerBank was 1.2 percent at December 31, 2019. EnerBank expects lending growth of up to ten percent annually over the next five years.
EnerBank’s loan portfolio was funded primarily by certificates of deposit of $2.4 billion. CMS Energy is required both by law and by contract to provide financial support, including infusing additional capital, to ensure that EnerBank satisfies mandated capital requirements and has sufficient liquidity to operate. With its self-funding plan, EnerBank has exceeded these requirements historically and exceeded them as of December 31, 2019. For additional details regarding EnerBank’s loan portfolio, see Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 8, Notes Receivable.
Other Outlook and Uncertainties
Employee Separation Program: In December 2019, CMS Energy and Consumers announced a voluntary separation program for non-union employees. Under the program, employees elected to request separation, and management decided which requests to accept. In January 2020, management communicated its decisions to affected employees, who will have 45 days to decide whether to separate. CMS Energy and Consumers estimate that they will recognize an after-tax charge of up to $10 million in 2020 related to the program. As a result of the program, however, CMS Energy and Consumers expect to benefit from future cost savings, as employee staffing levels will be better matched to workload demand, which reflects the companies’ ongoing workforce productivity improvements.
Litigation: CMS Energy, Consumers, and certain of their subsidiaries are named as parties in various litigation matters, as well as in administrative proceedings before various courts and governmental agencies, arising in the ordinary course of business. For additional details regarding these and other legal matters, see Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 3,2, Regulatory Matters and Note 4,3, Contingencies and Commitments.

Critical Accounting Policies and Estimates
The following information is important to understand CMS Energy’s and Consumers’ results of operations and financial condition. For additional accounting policies, see Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 1, Significant Accounting Policies.
In the preparation of CMS Energy’s and Consumers’ consolidated financial statements, estimates and assumptions are used that may affect reported amounts and disclosures. CMS Energy and Consumers use accounting estimates for asset valuations, unbilled revenue, depreciation, amortization, financial and derivative instruments, employee benefits, stock-based compensation, the effects of regulation, indemnities, contingencies, and contingencies.AROs. Actual results may differ from estimated results due to changes in the regulatory environment, regulatory decisions, lawsuits, competition, and other factors. CMS Energy and Consumers consider all relevant factors in making these assessments.
Accounting for the Effects of Industry Regulation: Because Consumers has regulated operations, it uses regulatory accounting to recognize the effects of the regulators’ decisions on its financial statements. Consumers continually assesses whether future recovery of its regulatory assets is probable by considering communications and experience with its regulators and changes in the regulatory environment. If Consumers determined that recovery of a regulatory asset were not probable, Consumers would be required to write off the asset and immediately recognize the expense in earnings.
Contingencies: CMS Energy and Consumers make judgments regarding the future outcome of various matters that give rise to contingent liabilities. For such matters, they record liabilities when they are considered probable and reasonably estimable, based on all available information. In particular, CMS Energy and Consumers are participating in various environmental remediation projects for which they have recorded liabilities. The recorded amounts represent estimates that may take into account such considerations as the number of sites, the anticipated scope, cost, and timing of remediation work, the available technology, applicable regulations, and the requirements of governmental authorities. For remediation projects in which the timing of estimated expenditures is considered reliably determinable, CMS Energy and Consumers record the liability at its net present value, using a discount rate equal to the interest rate on monetary assets that are essentially risk-free and have maturities comparable to that of the environmental liability. The amount recorded for any contingency may differ from actual costs incurred when the contingency is resolved. For additional details, see Item 8. Financial Statements and
83

Supplementary Data—Notes to the Consolidated Financial Statements—Note 4,3, Contingencies and Commitments.
Derivative Instruments: CMS Energy and Consumers account for certain contracts as derivative instruments. If a contract is a derivative and does not qualify for the normal purchases and sales exception, it is recorded on the consolidated balance sheets at its fair value. At CMS Energy, if the derivative is accounted for as a cash flow hedge, unrealized gains and losses from changes in the fair value of the derivative are recognized in AOCI and subsequently recognized in earnings when the hedged transactions impact earnings. If the derivative is accounted for as a fair value hedge, changes in the fair value of the derivative and changes in the fair value of the hedged item due to the hedged risk are recognized in earnings. For the FTRs at Consumers, changes in fair value are deferred as regulatory assets or liabilities.
The criteria used to determine if an instrument qualifies for derivative accounting or for an exception from derivative accounting are complex and often require judgment in application. Changes in business strategies or market conditions, as well as a requirement to apply different interpretations of the derivative accounting literature, could result in changes in accounting for a single contract or groups of contracts, which could have a material impact on CMS Energy’s and Consumers’ financial statements. For


81



additional details on CMS Energy’s and Consumers’ derivatives and how the fair values of derivatives are determined, see Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 6,5, Fair Value Measurements.
Income Taxes: The amount of income taxes paid by CMS Energy is subject to ongoing audits by federal, state, and foreign tax authorities, which can result in proposed assessments. An estimate of the potential outcome of any uncertain tax issue is highly judgmental. CMS Energy believes adequate reserves have been provided for these exposures; however, future results may include favorable or unfavorable adjustments to the estimated tax liabilities in the period the assessments are made or resolved or when statutes of limitation on potential assessments expire. Additionally, CMS Energy’s judgment as to the ability to recover its deferred tax assets may change. CMS Energy believes the valuation allowances related to its deferred tax assets are adequate, but future results may include favorable or unfavorable adjustments. As a result, CMS Energy’s effective tax rate may fluctuate significantly over time. For additional details, see Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 14,12, Income Taxes.
Pension and OPEB: CMS Energy and Consumers provide retirement pension benefits to certain employees under non‑contributory DB Pension Plans, and they provide postretirement health and life benefits to qualifying retired employees under an OPEB Plan.
CMS Energy and Consumers record liabilities for pension and OPEB on their consolidated balance sheets at the present value of the future obligations, net of any plan assets. The calculation of the liabilities and associated expenses requires the expertise of actuaries, and requires many assumptions, including:
life expectancies
discount rates
expected long-term rate of return on plan assets
rate of compensation increases
expected health care costs
A change in these assumptions could change significantly CMS Energy’s and Consumers’ recorded liabilities and associated expenses.

Presented in the following table are estimates of costscredits and cash contributions through 20222024 for the DB Pension Plans and OPEB Plan. Actual future costs, credits, and contributions will depend on future investment performance, discount rates, and various factors related to the participants of the DB Pension Plans and OPEB Plan. CMS Energy and Consumers will, at a minimum, contribute to the plans as needed to comply with federal funding requirements.

Consumers’ pension and OPEB costs are recoverable through its general ratemaking process.
Lowering the expected long-term rate of return on the assets of the DB Pension Plans by 25 basis points would increase estimated pension cost for 20202022 by $6$8 million for both CMS Energy and Consumers. Lowering the PBO discount rates by 25 basis points would increase estimated pension cost for 20202022 by $6$5 million for both CMS Energy and Consumers.
Pension and OPEB plan assets are accounted for and disclosed at fair value. Fair value measurements incorporate assumptions that market participants would use in pricing an asset or liability, including assumptions about risk. Development of these assumptions may require judgment.
For additional details on postretirement benefits, including the fair value measurements for the assets of the DB Pension Plans and OPEB Plan, see Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 12,10, Retirement Benefits.
Unbilled Revenues: Consumers’ customers are billed monthly in cycles having billing dates that do not generally coincide with the end of a calendar month. This results in customers having received electricity or natural gas that they have not been billed for as of the month-end. Consumers estimates its unbilled revenues by applying an average billed rate to total unbilled deliveries for each customer class. Consumers records unbilled revenues as accounts receivable and accrued revenue on its consolidated balance sheet. For additional information on unbilled revenues, see Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 16,14, Revenue.

Item 7A.    Quantitative and Qualitative Disclosures About Market Risk
CMS Energy and Consumers are exposed to market risks including, but not limited to, changes in interest rates, commodity prices, and investment security prices. They may enter into various risk management contracts to mitigate exposure to these risks, including swaps, options, futures, and forward contracts. CMS Energy and Consumers enter into these contracts using established policies and procedures, under the direction of an executive oversight committee consisting of certain officers and a risk committee consisting of those and other officers and business managers.
The following risk sensitivities illustrate the potential loss in fair value, cash flows, or future earnings from financial instruments, assuming a hypothetical adverse change in market rates or prices of ten percent. Potential losses could exceed the amounts shown in the sensitivity analyses if changes in market rates or prices were to exceed ten percent.
Interest-Rate Risk
Long-Term Debt: CMS Energy and Consumers are exposed to interest-rate risk resulting from issuing fixed-rate and variable-rate debt instruments. CMS Energy and Consumers use a combination of these instruments, and may also enter into interest-rate swap agreements, in order to manage this risk and to achieve a reasonable cost of capital.

The fair value losses in the above table could be realized only if CMS Energy and Consumers transferred all of their fixed-rate financing to other creditors. The annual earnings exposure related to variable-rate financing was immaterial for both CMS Energy and Consumers at December 31, 20192021 and 2018,2020, assuming an adverse change in market interest rates of ten percent.
Notes Receivable: CMS Energy is exposed to interest-rate risk resulting from EnerBank’s fixed-rate installment loans. EnerBank provides unsecured consumer installment loans, largely for financing home improvements.

CMS Energy Corporation
Consumers Energy Company
Notes to the Consolidated Financial Statements
1:Significant Accounting Policies
1:    Significant Accounting Policies
Principles of Consolidation: CMS Energy and Consumers prepare their consolidated financial statements in conformity with GAAP. CMS Energy’s consolidated financial statements comprise CMS Energy, Consumers, CMS Enterprises, EnerBank, and all other entities in which CMS Energy has a controlling financial interest or is the primary beneficiary. Consumers’ consolidated financial statements comprise Consumers and all other entities in which it has a controlling financial interest or is the primary beneficiary.interest. CMS Energy uses the equity method of accounting for investments in companies and partnerships that are not consolidated, where they have significant influence over operations and financial policies but are not the primary beneficiary. CMS Energy and Consumers eliminate intercompany transactions and balances.
Use of Estimates: CMS Energy and Consumers are required to make estimates using assumptions that may affect reported amounts and disclosures. Actual results could differ from those estimates.
Contingencies: CMS Energy and Consumers record estimated liabilities forloss contingencies on their consolidated financial statements when it is probable that a liabilityloss has been incurred and when the amount of loss can be reasonably estimated. For environmental remediation projects in which the timing of estimated expenditures is considered reliably determinable, CMS Energy and Consumers record the liability at its net present value, using a discount rate equal to the interest rate on monetary assets that are essentially risk-free and have maturities comparable to that of the environmental liability. CMS Energy and Consumers expense legal fees as incurred; fees incurred but not yet billed are accrued based on estimates of work performed.
Debt Issuance Costs, Discounts, Premiums, and Refinancing Costs: Upon the issuance of long-term debt, CMS Energy and Consumers defer issuance costs, discounts, and premiums and amortize those amounts over the terms of the associated debt. Debt issuance costs are presented as a direct deduction from the carrying amount of long-term debt on the balance sheet. Upon the refinancing of long-term debt, Consumers, as a regulated entity, defers any remaining unamortized issuance costs, discounts, and premiums associated with the refinanced debt and amortizes those amounts over the term of the newly issued debt. For the non‑regulated portions of CMS Energy’s business, any remaining unamortized issuance costs, discounts, and premiums associated with extinguished debt are charged to earnings.
Derivative Instruments: In order to support ongoing operations, CMS Energy and Consumers enter into contracts for the future purchase and sale of various commodities, such as electricity, natural gas, and coal. These forward contracts are generally long-term in nature and result in physical delivery of the commodity at a contracted price. Most of these contracts are not subject to derivative accounting for one or more of the following reasons:
they do not have a notional amount (that is, a number of units specified in a derivative instrument, such as MWh of electricity or bcf of natural gas)
they qualify for the normal purchases and sales exception
they cannot be net settled due in part to the absence of an active market for the commodity


105
101


Consumers also uses FTRs to manage price risk related to electricity transmission congestion. An FTR is a financial instrument that entitles its holder to receive compensation or requires its holder to remit payment for congestion-related transmission charges. Consumers accounts for FTRs as derivatives.
Additionally, CMS Energy uses interest rate swaps to manage its interest rate risk on certain long-term debt and notes receivable transactions.
CMS Energy and Consumers record derivative contracts that do not qualify for the normal purchases and sales exception at fair value on their consolidated balance sheets. At CMS Energy, if the derivative is accounted for as a cash flow hedge, unrealized gains and losses from changes in the fair value of the derivative are recognized in AOCI and subsequently recognized in earnings when the hedged transactions impact earnings. If the derivative is accounted for as a fair value hedge, changes in the fair value of the derivative and changes in the fair value of the hedged item due to the hedged risk are recognized in earnings. For the FTRs at Consumers, changes in fair value are deferred as regulatory assets or liabilities. For details regarding CMS Energy’s and Consumers’ derivative instruments recorded at fair value, see Note 6,5, Fair Value Measurements.
EPS: CMS Energy calculates basic and diluted EPS using the weighted-average number of shares of common stock and dilutive potential common stock outstanding during the period. Potential common stock, for purposes of determining diluted EPS, includes the effects of nonvested stock awards and forward equity sales. CMS Energy computes the effect on potential common stock using the treasury stock method. Diluted EPS excludes the impact of antidilutive securities, which are those securities resulting in an increase in EPS or a decrease in loss per share. For EPS computations, see Note 15,13, Earnings Per Share—CMS Energy.
Impairment of Long-Lived Assets and Equity Method Investments: CMS Energy and Consumers perform tests of impairment if certain triggering events occur that indicate the carrying amount of an asset may not be recoverable or ifthat there has been a decline in value that may be other than temporary.
CMS Energy and Consumers evaluate long-lived assets held in use for impairment by calculating the undiscounted future cash flows expected to result from the use of the asset and its eventual disposition. If the undiscounted future cash flows are less than the carrying amount, CMS Energy and Consumers recognize an impairment loss equal to the amount by which the carrying amount exceeds the fair value. CMS Energy and Consumers estimate the fair value of the asset using quoted market prices, market prices of similar assets, or discounted future cash flow analyses.
CMS Energy also assesses equity method investments for impairment whenever there has been a decline in value that is other than temporary. This assessment requires CMS Energy to determine the fair value of the equity method investment. CMS Energy determines fair value using valuation methodologies, including discounted cash flows, and assesses the ability of the investee to sustain an earnings capacity that justifies the carrying amount of the investment. CMS Energy records an impairment if the fair value is less than the carrying amount and the decline in value is considered to be other than temporary.
Investment Tax Credits: Consumers amortizes its investment tax credits over the life of the related property in accordance with regulatory treatment. CMS Energy’s non‑regulated businesses use the deferral method of accounting for investment tax credits. Under the deferral method, the book basis of the associated assets is reduced by the amount of the credit, resulting in lower depreciation expense over the life of the assets. Furthermore, the tax basis of the assets is reduced by 50 percent of the related credit, resulting in a net deferred tax asset. CMS Energy recognizes the tax benefit of this basis difference as a reduction to income tax expense in the year in which the plant reaches commercial operation.


106
102


Inventory: CMS Energy and Consumers use the weighted-average cost method for valuing working gas, recoverable base gas in underground storage facilities, and materials and supplies inventory. CMS Energy and Consumers also use this method for valuing coal inventory, and they classify these amounts as generating plant fuel stock on their consolidated balance sheets.
CMS Energy and Consumers account for RECs and emission allowances as inventory and use the weighted-average cost method to remove amounts from inventory. RECs and emission allowances are used to satisfy compliance obligations related to the generation of power. CMS Energy and Consumers classify these amounts within other assets on their consolidated balance sheets.
CMS Energy and Consumers evaluate inventory for impairment as required to ensure that its carrying value does not exceed the lower of cost or net realizable value.
MISO Transactions: MISO requires the submission of hourly day-ahead and real-time bids and offers for energy at locations across the MISO region. CMS Energy and Consumers account for MISO transactions on a net hourly basis in each of the real-time and day-ahead markets, netted across all MISO energy market locations. CMS Energy and Consumers record net hourly purchases in purchased and interchange power and net hourly sales in operating revenue on their consolidated statements of income. They record net billing adjustments upon receipt of settlement statements, record accruals for future net purchases and sales adjustments based on historical experience, and reconcile accruals to actual expenses and sales upon receipt of settlement statements.
Property Taxes: Property taxes are based on the taxable value of Consumers’ real and personal property assessed by local taxing authorities. Consumers records property tax expense over the fiscal year of the taxing authority for which the taxes are levied. The deferred property tax balance represents the amount of Consumers’ accrued property tax that will be recognized over future governmental fiscal periods.
Reclassifications: CMS Energy and Consumers have reclassified certain prior period amounts to conform to the presentation in the present period. The most significant of these reclassifications is related to CMS Energy’s sale of EnerBank to Regions Bank in October 2021. The assets and liabilities of EnerBank are presented as held for sale on CMS Energy’s consolidated balance sheets at December 31, 2020. Additionally, EnerBank’s results of operations through the date of the sale are presented as income from discontinued operations on CMS Energy’s consolidated statements of income for the years ended December 31, 2021, 2020, and 2019. For information regarding the sale of EnerBank, see Note 20, Exit Activities and Discontinued Operations.
Renewable Energy Grant: In 2013, Consumers received a renewable energy cash grant for Lake Winds® Energy Park under Section 1603 of the American Recovery and Reinvestment Tax Act of 2009. Upon receipt of the grant, Consumers recorded a regulatory liability, which Consumers is amortizing over the life of Lake Winds® Energy Park. Consumers presents the amortization as a reduction to maintenance and other operating expenses on its consolidated statements of income. Consumers recorded the deferred income taxes related to the grant as a reduction of the book basis of Lake Winds® Energy Park.

2:New Accounting Standards
Implementation of New Accounting Standards
ASU 201602, Leases: This standard, which was effective on January 1, 2019 for CMS Energy and Consumers, establishes a new accounting model for leases. The standard requires lessees to recognizeNote 19, Variable Interest Entities


2:    Regulatory Matters
103


lease assets and liabilities on the balance sheet for all leases with a term of more than one year, including operating leases, which were not recorded on the balance sheet under previous standards. The new guidance also amends the definition of a lease to require that a lessee have the right to control the use of a specified asset, and not simply control or take the output of the asset. On the statement of income, operating leases are generally accounted for under a straight-line expense model, while finance leases, which were previously referred to as capital leases, are generally accounted for under a financing model. Consistent with the previous lease guidance, however, the standard allows rate-regulated utilities to recognize expense consistent with the timing of recovery in rates.
CMS Energy and Consumers elected to use certain practical expedients permitted by the standard, under which they were not required to perform lease assessments or reassessments for agreements existing on the effective date. They also elected a transition method under which they initially applied the standard on January 1, 2019, without adjusting amounts presented for prior periods. Under the standard, CMS Energy and Consumers recognized additional lease assets and liabilities on their consolidated balance sheets as of January 1, 2019 for their operating leases. In addition, in accordance with the standard, they have provided additional disclosures about their leases in Note 10, Leases and Palisades Financing. The standard did not have any impact on CMS Energy’s and Consumers’ consolidated net income or cash flows, and there was no cumulative-effect adjustment recorded to beginning retained earnings.
New Accounting Standards Not Yet Effective
ASU 201613, Measurement of Credit Losses on Financial Instruments: This standard, effective January 1, 2020 for CMS Energy and Consumers, provides new guidance for measuring and recognizing credit losses on financial instruments. The standard applies to financial assets that are not measured at fair value through net income as well as to certain off-balance sheet credit exposures. Entities will apply the standard using a modified retrospective approach, with a cumulative‑effect adjustment recorded to beginning retained earnings on the effective date.
The standard will require an increase to the allowance for loan losses at EnerBank. At December 31, 2019, the allowance reflected expected credit losses over a 12‑month period, but the new standard will require the allowance to reflect expected credit losses over the entire life of the loans. EnerBank expects to record a $65 million increase to its expected credit loss reserves on January 1, 2020, with the offsetting adjustment recorded to retained earnings, net of taxes. The standard will also require an increase in the initial provision for loan losses recognized in net income for new loans originated in 2020 and beyond. At Consumers, the new guidance will apply to the allowance for uncollectible accounts; however, Consumers does not expect material impacts from the standard.

3:Regulatory Matters
Regulatory matters are critical to Consumers. The Michigan Attorney General, ABATE, the MPSC Staff, and certain other parties typically participate in MPSC proceedings concerning Consumers, such as Consumers’ rate cases and PSCR and GCR processes. These parties often challenge various aspects of those proceedings, including the prudence of Consumers’ policies and practices, and seek cost disallowances and other relief. The parties also have appealed significant MPSC orders. Depending upon the specific issues, the outcomes of rate cases and proceedings, including judicial proceedings challenging MPSC orders or other actions, could negatively affect CMS Energy’s and Consumers’ liquidity, financial condition, and results of operations. Consumers cannot predict the outcome of these proceedings.
There are multiple appeals pending that involve various issues concerning cost recovery from customers, the adequacy of the record of evidence supporting the recovery of Smart Energy investments,MPSC’s authority to approve voluntary revenue refunds, and other matters. Consumers is unable to predict the outcome of these appeals.
Regulatory Assets and Liabilities
Consumers is subject to the actions of the MPSC and FERC and therefore prepares its consolidated financial statements in accordance with the provisions of regulatory accounting. A utility must apply regulatory accounting when its rates are designed to recover specific costs of providing regulated services. Under regulatory accounting, Consumers records regulatory assets or liabilities for certain transactions that would have been treated as expense or revenue by non‑regulated businesses.

Regulatory Assets
Energy Waste Reduction Plan Incentive: The energy waste reduction incentive mechanism provides a financial incentive if the energy savings of Consumers’ customers exceed annual targets established by the MPSC. Consumers accounts for this program as an alternative-revenue program that meets the criteria for recognizing revenue related to the incentive as soon as energy savings exceed the annual targets established by the MPSC.
In December 2019,October 2021, the MPSC approved a settlement agreement authorizing Consumers to collect $34$42 million during 20202022 as an incentive for exceeding its statutory savings targets in 2018.2020. Consumers recognized incentive revenue under this program of $34$42 million in 2018.2020.
Consumers also exceeded its statutory savings targets in 2019,2021, achieved certain other goals, and will request the MPSC’s approval to collect $34$46 million, the maximum performance incentive, in the energy waste reduction reconciliation to be filed in 2020.May 2022. Consumers recognized incentive revenue under this program of $34$46 million in 2019.2021.
Deferred Capital Spending: In 2019, the MPSC approved a settlement agreement in Consumers’ 2018 electric rate case, which provided deferred accounting treatment for distribution-related capital investments exceeding certain threshold amounts. Thus, for actual capital spending above the threshold amounts detailed in the settlement agreement, Consumers had deferred as a regulatory asset the associated depreciation and property tax expense as well as the debt component of the overall rate of return on such spending.
Postretirement Benefits: As part of the ratemaking process, the MPSC allows Consumers to recover the costs of postretirement benefits. Accordingly, Consumers defers the net impact of actuarial losses and gains, as well as prior service costs and credits, and settlements associated with postretirement benefits as a regulatory asset or liability. The asset or liability will decrease as the deferred items are amortized and recognized as components of net periodic benefit cost. For details about settlements and the amortization periods, see Note 12,10, Retirement Benefits.
Costs of Coal-fueled Electric Generating Units to be Retired: In June 2019, the MPSC approved the settlement agreement reached in Consumers’ 2018 IRP, under which Consumers plans to retire the D.E. Karn 1 & 2 coal-fueled electric generating units in 2023. Under Michigan law, electric utilities have been permitted to use highly rated, low-cost securitization bonds to finance the recovery of qualified costs. Consumers will file for securitization financing by May 2023, requesting the MPSC’s approval to securitize the remaining book value of the 2 coal-fueled electric generating units upon their retirement.
In 2019, Consumers removed from total plant, property, and equipment an amount representing the projected remaining book value of the 2 coal-fueled electric generating units upon their retirement, and recorded it as a regulatory asset. Until securitization, the book value of the generating units will remain in rate base and receive full regulatory returns in general rate cases.
In December 2020, the MPSC issued a securitization financing order authorizing Consumers to issue securitization bonds in order to finance the recovery of the remaining book value of the 2 coal-fueled electric generating units upon their retirement. An intervenor appealed the order, contending that it should not have to pay the securitization surcharge. In November 2021, the Michigan Court of Appeals affirmed the MPSC’s determination that the intervenor must pay the securitization charge.

ARO: The recovery of the underlying asset investments and related removal and monitoring costs of recorded AROs is approved by the MPSC in depreciation rate cases. Consumers records a regulatory asset and a regulatory liability for timing differences between the recognition of AROs for financial reporting purposes and the recovery of these costs from customers. The recovery period approximates the useful life of the assets to be removed.
Securitized Costs: In 2013, the MPSC issued a securitization financing order authorizing Consumers to issue securitization bonds in order to finance the recovery of the remaining book value of 7 smaller coal-fueled electric generating units that Consumers retired in 2016 and 3 smaller natural gas-fueled electric generating units that Consumers retired in 2015. Upon receipt of the MPSC’s order, Consumers removed the book value of the 10 units from plant, property, and equipment and recorded this amount as a regulatory asset. Consumers is amortizing the regulatory asset over the life of the related securitization bonds, which it issued through a subsidiary in 2014. For additional details regarding the securitization bonds, see Note 5,4, Financings and Capitalization.
ARO: The recovery of the underlying asset investments and related removal and monitoring costs of recorded AROs is approved by the MPSC in depreciation rate cases. Consumers records a regulatory asset and a regulatory liability for timing differences between the recognition of AROs for financial reporting purposes and the recovery of these costs from customers. The recovery period approximates the useful life of the assets to be removed.


107


MGP Sites: Consumers is incurring environmental remediation and other response activity costs at 23 former MGP facilities. The MPSC allows Consumers to recover from its natural gas customers over a ten-year period the costs incurred to remediate the MGP sites.
Unamortized Loss on Reacquired Debt: Under regulatory accounting, any unamortized discount, premium, or expense related to debt redeemed with the proceeds of new debt is capitalized and amortized over the life of the new debt.
Energy Waste Reduction Plan: The MPSC allows Consumers to collect surcharges from customers to fund its energy waste reduction plan. The amount of spending incurred in excess of surcharges collected is recorded as a regulatory asset and amortized as surcharges are collected from customers over the plan period. The amount of surcharges collected in excess of spending incurred is recorded as a regulatory liability and amortized as costs are incurred.
Deferred Capital Spending:Demand Response Program: In January 2019,Consumers’ 2018 IRP and general rate cases, the MPSC has approved the recovery of demand response costs. Consumers annually files a settlement agreement in Consumers’ 2018 electric rate case, which provided deferred accounting treatment for distribution-related capital investments exceeding certain threshold amounts. Thus, forreconciliation with the MPSC to review actual capital spending above the thresholddemand response costs against amounts detailed in the settlement agreement, Consumers has deferred as a regulatory asset the associated depreciation and property tax expense as well as the debt component of the overall rate of return on such spending.approved.
Gas Storage Inventory Adjustments: Consumers incurs inventory expenses related to the loss of gas from its natural gas storage fields. The MPSC allows Consumers to recover these costs from its natural gas customers over a five-year period.
Regulatory Liabilities
Income Taxes, Net: Consumers records regulatory assets and liabilities to reflect the difference between deferred income taxes recognized for financial reporting purposes and amounts previously reflected in Consumers’ rates. This net balance will decrease over the remaining life of the related temporary differences and flow through current income tax benefit.expense. The majority of the net regulatory liability recorded related to income taxes is associated with plant assets that are subject to normalization, which is governed by the Internal Revenue Code, and will be returned to customers over the remaining book life of the related plant assets, the average of which is 44 years for gas plant assets and 27 years for electric plant assets. For additional details on deferred income taxes, see the Consumers Electric Utility and Gas Utility—Tax Cuts and Jobs Act section below and Note 14,12, Income Taxes.
Gain to be Shared with Customers:Reserve for Customer Refunds: In December 2019,2020, the MPSC issued an order authorizing Consumers to refund $28 million voluntarily to utility customers. In May 2021, the MPSC approved a filing submitted by Consumers that proposed the refund take the form of incremental spending in 2021 and 2022 above amounts included in rates on various programs, including electric service restoration and gas and electric technology expenses. If Consumers does not achieve the incremental spending, the remaining balance will be provided to electric or gas utility customers through a bill credit.
111

Voluntary Transmission Asset Sale Gain Share: In October 2020, Consumers completed a sale of the electric utility’s remaining transmission equipment to METC. In December 2020, Consumers filed an application with the MPSC requesting approval to share voluntarily half of the gain from the sale with electric utility customers half of the gain recognized on a sale of a portion of its substation transmission equipment to METC. Consumers proposed the gain sharing take place through an offset to additionalincremental service restoration spending in 2021; this application was approved by the MPSC in February 2021. As a result, the $14 million gain was recorded on Consumers’ consolidated balance sheets as a current regulatory liability at December 31, 2020 or through a bill credit toand wasshared with customers in 2021.
Reserve for Customer Refunds: At December 31, 2018, Consumers had recorded a provision for revenue subject to refund associated with electric rates it self-implemented in 2017. In August 2019, the MPSC approved Consumers’ reconciliation of total revenues collected from rates it self-implemented to those that would have been collected under the final rates approved in June 2018 and Consumers refunded the resulting amount in September 2019. The 2016 Energy Law eliminated utilities’ self-implementation of rates under general rate cases, but provided for more timely processing of general rate cases.
TCJA Reserve for Refund: In early 2018, the MPSC ordered Consumers to file various proceedings to determine the reduction in its electric and gas revenue requirements as a result of the TCJA. For further information on the various TCJA proceedings, see the Consumers Electric Utility and Gas Utility—Tax Cuts and Jobs Act section below.


108


Cost of Removal: The MPSC allows Consumers to collect amounts from customers to fund future asset removal activities. This regulatory liability is reduced as costs of removal are incurred. The refund period of this regulatory liability approximates the useful life of the assets to be removed.
Renewable Energy Grant: In 2013, Consumers received a $69 million renewable energy grant for Lake Winds® Energy Park, which began operations in 2012. This grant reduces Consumers’ cost of complying with Michigan’s renewable portfolio standard and, accordingly, reduces the overall renewable energy surcharge to be collected from customers. The regulatory liability recorded for the grant will be amortized over the life of Lake Winds® Energy Park.
Renewable Energy Plan: Consumers has collected surcharges to fund its renewable energy plan. Amounts not yet spent under the plan are recorded as a regulatory liability, which is amortized as incremental costs are incurred to operate and depreciate Consumers’ renewable generation facilities and to purchase RECs under renewable energy purchase agreements. Incremental costs represent costs incurred in excess of amounts recovered through the PSCR process.
Consumers Electric Utility and Gas Utility
Tax Cuts and Jobs Act: The TCJA, which changed existing federal tax law and included numerous provisions that affect businesses, was signed into law in December 2017.
In early 2018, the MPSC ordered Consumers to file various proceedings to determine the reduction in its electric and gas revenue requirements as a result of the reduction in the corporate income tax rate, and to implement bill credits to reflect that reduction until customer rates could be adjusted through Consumers’ general rate cases. Consumers filed, and the MPSC approved, such proceedings throughout 2018, resulting in credits to customer bills during 2018 to reflect reductions in Consumers’ electric and gas revenue requirements.
Consumers filed additional proceedings to address amounts collected from customers during 2018 prior to the implementation of bill credits. In late 2018, the MPSC approved the refund of $31 million to gas customers over six months beginning in December 2018 and the refund of $70 million to electric customers over six months beginning in January 2019.
In October 2018, Consumers filed an application to address the December 31, 2017 remeasurement of its deferred income taxes and other base rate impacts of the TCJA on customers. In September 2019, the MPSC authorized Consumers to begin returning net regulatory tax liabilities of $0.4 billion to gas customers through rates approved in the 2018 gas rate case and $1.2 billion to electric customers through rates to be determined in Consumers’ next electric rate case. Until then, the MPSC authorized Consumers to refund $32 million to electric customers through a temporary bill credit. Consumers’ total $1.6 billion of net regulatory tax liabilities comprises:
A regulatory tax liability of $1.7 billion associated with plant assets that are subject to normalization, which is governed by the Internal Revenue Code; this regulatory tax liability will be returned over the remaining book life of the related plant assets, the average of which is 44 years for gas plant assets and 27 years for electric plant assets.
A regulatory tax asset of $0.3 billion associated with plant assets that are not subject to normalization; this regulatory tax asset will be collected over 44 years from gas customers and over 27 years from electric customers.
A regulatory tax liability of $0.2 billion, which is primarily related to employee benefits; this regulatory tax liability will be refunded to customers over ten years.


109


In January 2018, Consumers began to reduce the regulatory liability subject to normalization by crediting income tax expense. Consumers fully reserved for the eventual refund of these excess deferred taxes that it credited to income tax expense in a separate non‑current regulatory liability established by reducing revenue. As a result of an order received in September 2019, Consumers began refunding these excess deferred taxes to customers and will no longer reserve for their refund. At the date of the order, this reserve for refund of these excess deferred taxes totaled $62 million. For additional details on the remeasurement, see Note 14, Income Taxes.
Consumers Electric Utility
20182021 Electric Rate Case: In May 2018,March 2021, Consumers filed an application with the MPSC seeking an annual rate increase of $58$225 million, based on a 10.7510.5 percent authorized return on equity.equity and a projected twelve-month period ending December 31, 2022. In October 2018,July 2021, Consumers reduced its requested annual rate increase to $44$201 million. In January 2019, the MPSC approved a settlement agreement authorizing an annual rate decrease of $24 million, based on a 10.0 percent authorized return on equity. With the elimination of the $113 million TCJA credit to customer bills, the approved settlement agreement resulted in an $89 million net increase in annual rates. The settlement agreement also provided for deferred accounting treatment for distribution-related capital investments exceeding certain amounts. Consumers also agreed to not file a new electric rate case prior to January 2020.
Consumers Gas Utility
2018 Gas Rate Case: In November 2018, Consumers filed an application with the MPSC seeking an annual rate increase of $229 million, based on a 10.75 percent authorized return on equity. In April 2019, Consumers reduced its requested annual rate increase to $204 million. In September 2019,December 2021, the MPSC approved an annual rate increase of $144$27 million, based on a 9.909.9 percent authorized return on equity. This increase reflects the net impact of the approved settlement agreement in Consumers’ electric depreciation rate case, which reduced annual depreciation expense by $27 million.
In its final order, the MPSC disallowed cost recovery for fleet assets and certain other categories of recently completed capital expenditures incurred by Consumers. As a result of this disallowance, Consumers recorded an impairment charge of $41 million within maintenance and other operating expenses on its consolidated statements of income for the year ended December 31, 2021. This charge includes a $13an assessment of probable loss of $11 million adjustmenton similar categories of gas utility capital expenditures that are pending recovery in Consumers’ 2021 gas rate case. Though Consumers plans to begin returning net regulatory tax liabilities associated withpursue full recovery of certain of these electric and gas capital expenditures, the TCJA to customers. The MPSC also approved the continuation of a revenue decoupling mechanism, which annually reconciles Consumers’ actual weather-normalized, non‑fuel revenues with the revenues approvedposition taken by the MPSC.MPSC in this electric rate case provides significant uncertainty around whether Consumers will ultimately succeed.
In January 2022, Consumers filed a petition for rehearing requesting the MPSC reconsider its disallowance of $11 million in capital expenditures for which the MPSC had already approved recovery in a previous electric rate order; this amount was not included in the impairment charge based on Consumers’ assessment of the merits of the petition for rehearing. The order disallowed recovery of other categories of capital expenditures, requiring that Consumers provide additional cost/benefit analysis and other information in its next electric rate case to support cost recovery. Consumers has incurred approximately $23 million related to these programs as of December 31, 2021 and, for certain ongoing projects, expects to incur additional capital expenditures in 2022 and beyond. While Consumers intends to
112

support fully the prudency of such capital expenditures, it is reasonably possible that the MPSC will disallow some or all of these capital expenditures. An additional material disallowance of incurred capital costs could negatively affect CMS Energy’s and Consumers’ future results of operations. Consumers cannot predict the outcome of these proceedings.
Finally, the order disallowed various other categories of capital expenditures in the projected test year, primarily challenging the accuracy of Consumers’ projection of these expenditures through 2022. While these are presently excluded from rate base, Consumers believes it will be successful in recovering the actual capital expenditures incurred for these programs in future rate cases.
As a result of the order, in December 2021, Consumers committed to a plan to sell fleet assets with a fair value of $15 million. To reflect these held-for-sale assets at their fair value, less expected selling costs, Consumers recorded an additional impairment charge of $4 million within maintenance and other operating expenses on its consolidated statements of income for the year ended December 31, 2021.
Power Supply Cost Recovery and Gas Cost Recovery
The PSCR and GCR ratemaking processes are designed to allow Consumers to recover all of its power supply and purchased natural gas costs if incurred under reasonable and prudent policies and practices. The MPSC reviews these costs, policies, and practices in annual plan and reconciliation proceedings. Consumers adjusts its PSCR and GCR billing charges monthly in order to minimize the underrecovery or overrecovery amount in the annual reconciliations. Underrecoveries represent probable future revenues that will be recovered from customers; overrecoveries represent previously collected revenues that will be refunded to customers.

PSCR Plans and Reconciliations: In October 2019,2021, the MPSC issued an order in Consumers’ 20172019 PSCR reconciliation, authorizing recovery of $1.9 billion of power costs and authorizing Consumers to reflect in its 20182020 PSCR reconciliation the overrecovery of $32$18 million.
In November 2019,April 2021, the MPSC issued an order in Consumers’ 20182020 PSCR plan authorizing the 20182020 PSCR charge that Consumers self-implemented beginning in January 2018.2020. In March 2019,2021, Consumers filed its 20182020 PSCR reconciliation, requesting full recovery of $2.0$1.8 billion of power costs and authorization to reflect in its 20192021 PSCR reconciliation the underrecovery of $31 million.$4 million.

4:Contingencies and Commitments
3:    Contingencies and Commitments
CMS Energy and Consumers are involved in various matters that give rise to contingent liabilities. Depending on the specific issues, the resolution of these contingencies could negatively affect CMS Energy’s and Consumers’ liquidity, financial condition, and results of operations. In their disclosures of these matters, CMS Energy and Consumers provide an estimate of the possible loss or range of loss when such an estimate can be made. Disclosures that state that CMS Energy or Consumers cannot predict the outcome of a matter indicate that they are unable to estimate a possible loss or range of loss for the matter.
CMS Energy Contingencies
Gas Index Price Reporting Litigation: CMS Energy, along with CMS MST, CMS Field Services, Cantera Natural Gas, Inc., and Cantera Gas Company, were named as defendants in 4 class action lawsuits and 1 individual lawsuit arising as a result of alleged inaccurate natural gas price reporting to


111


publications that report trade information. Allegations include price-fixing conspiracies, restraint of trade, and artificial inflation of natural gas retail prices in Kansas, Missouri, and Wisconsin. In 2016, CMS Energy entities reached a settlement with the plaintiffs in the Kansas and Missouri class action cases for an amount that was not material to CMS Energy. In 2017, the federal district court approved the settlement. The following provides more detail on the remaining cases in which CMS Energy or its affiliates were named as parties:
In 2006, a class action complaint, Arandell Corp., et al. v. XCEL Energy Inc., et al., was filed in Wisconsin state court on behalf of Wisconsin commercial entities that purchased natural gas between January 2000 and October 2002. The defendants, including CMS Energy, CMS ERM, and Cantera Gas Company, are alleged to have violated Wisconsin’s antitrust statute. The plaintiffs are seeking full consideration damages, treble damages, costs, interest, and attorneys’ fees.
In 2009, a class action complaint, Newpage Wisconsin System v. CMS ERM, et al., was filed in circuit court in Wood County, Wisconsin, against CMS Energy, CMS ERM, Cantera Gas Company, and others. The plaintiff is seeking full consideration damages, treble damages, costs, interest, and attorneys’ fees.
In 2005, J.P. Morgan Trust Company, N.A., in its capacity as trustee of the FLI Liquidating Trust, filed an action in Kansas state court against CMS Energy, CMS MST, CMS Field Services, and others. The complaint alleges various claims under the Kansas Restraint of Trade Act. The plaintiff is seeking statutory full consideration damages for its purchases of natural gas in 2000 and 2001, costs, and attorneys’ fees.
After removal to federal court, all of the cases were transferred to a single federal district court pursuant to the multidistrict litigation process. In 2010 and 2011, all claims against CMS Energy defendants were dismissed by the district court based on FERC preemption.
In 2013, the U.S. Court of Appeals for the Ninth Circuit reversed the district court decision. The appellate court found that FERC preemption does not apply under the facts of these cases. The appellate court affirmed the district court’s denial of leave to amend to add federal antitrust claims. The matter was appealed to the U.S. Supreme Court, which in 2015 upheld the Ninth Circuit’s decision. The cases were remanded back to the federal district court.
In 2016, the federal district court granted the defendants’ motion for summary judgment in the individual lawsuit filed in Kansas based on a release in a prior settlement involving similar allegations; the order of summary judgment was subsequently appealed. In March 2018, the U.S. Court of Appeals for the Ninth Circuit reversed the lower court’s ruling and remanded the case back to the federal district court.
In 2017, the federal district court denied plaintiffs’ motion for class certification in the two pending class action cases in Wisconsin. The plaintiffs appealed that decision to the U.S. Court of Appeals for the Ninth Circuit and in August 2018, the Ninth Circuit Court of Appeals reversed and remanded the matter back to the federal district court for further consideration.
In January 2019, the judge in the multidistrict litigation granted motions filed by plaintiffs for Suggestion of Remand of the actions back to the respective transferor courts in Wisconsin and Kansas for further handling. In the Kansas action, the Judicial Panel on Multidistrict Litigation ordered the remand and the case has been transferred. In the Wisconsin actions, oppositions to the remand were filed, but the Judicial Panel on Multidistrict Litigation granted the remand in June 2019.


112


CMS Energy and the plaintiffs in each of the Kansas and the Wisconsin actions engaged in settlement discussions and CMS Energy has recorded a $30 million liability at December 31, 2019 as a probable estimate to settle these two cases. CMS Energy can give no assurances that it can reach a final settlement with the plaintiffs in these two cases, of the actual amount CMS Energy would have to pay in any settlement, or, in the Wisconsin case, that the Wisconsin court would approve any such settlement. If settlement does not occur and the outcome after appeals is unfavorable to CMS Energy, these cases could negatively affect CMS Energy’s liquidity, financial condition, and results of operations.
Bay Harbor: CMS Land retained environmental remediation obligations for the collection and treatment of leachate at Bay Harbor after selling its interests in the development in 2002. Leachate is produced when water enters into cement kiln dust piles left over from former cement plant operations at the site. In 2012, CMS Land and EGLE finalized an agreement that established the final remedies and the future water quality criteria at the site. CMS Land completed all construction necessary to implement the remedies required by the agreement and will continue to maintain and operate a system to discharge treated leachate into Little Traverse Bay under an NPDES permit, issued in 2010 andwhich was renewed in 2016. The renewed NPDES permitJanuary 2022 and is valid through September 2020.2025.
At December 31, 2019,2021, CMS Energy had a recorded liability of $46$45 million for its remaining obligations for environmental remediation. CMS Energy calculated this liability based on discounted projected costs, using a discount rate of 4.34 percent and an inflation rate of 1 percent on annual operating and maintenance costs. The undiscounted amount of the remaining obligation is $58$57 million. CMS Energy expects to pay the following amounts for long-term leachate disposal and operating and maintenance costs in each of the next five years:

CMS Energy’s estimate of response activity costs and the timing of expenditures could change if there are changes in circumstances or assumptions used in calculating the liability. Although a liability for its present estimate of remaining response activity costs has been recorded, CMS Energy cannot predict the ultimate financial impact or outcome of this matter.

Equatorial Guinea Tax Claim: In 2002, CMS Energy sold its oil, gas, and methanol investments in Equatorial Guinea. The government of Equatorial Guinea claims that, in connection with the sale, CMS Energy owes $152 million in taxes, plus substantial penalties and interest that could be up to or exceed the amount of the taxes claimed. In 2015, the matter was proceeding to formal arbitration; however, since then, the government of Equatorial Guinea has stopped communicating.communicating with CMS Energy. CMS Energy has concluded that the government’s tax claim is without merit and will continuebelieves the likelihood of material loss to contest the claim,be remote, but cannot predict the financial impact or outcome of the matter. An unfavorable outcome could have a material adverse effect on CMS Energy’s liquidity, financial condition, and results of operations.
Consumers Electric Utility Contingencies
Electric Environmental Matters: Consumers’ operations are subject to environmental laws and regulations. Historically, Consumers has generally been able to recover, in customer rates, the costs to operate its facilities in compliance with these laws and regulations.


113


Cleanup and Solid Waste: Consumers expects to incur remediation and other response activity costs at a number of sites under the NREPA. Consumers believes that these costs should be recoverable in rates, but cannot guarantee that outcome. Consumers estimates that its liability for NREPA sites for which it can estimate a range of loss will be between $3$2 million and $4 million. At December 31, 2019,2021, Consumers had a recorded liability of $3$2 million, the minimum amount in the range of its estimated probable NREPA liability, as no amount in the range was considered a better estimate than any other amount.
Consumers is a potentially responsible party at a number of contaminated sites administered under CERCLA. CERCLA liability is joint and several. In 2010, Consumers received official notification from the EPA that identified Consumers as a potentially responsible party for cleanup of PCBs at the Kalamazoo River CERCLA site. The notification claimed that the EPA has reason to believe that Consumers disposed of PCBs and arranged for the disposal and treatment of PCB-containing materials at portions of the site. In 2011, Consumers received a follow-up letter from the EPA requesting that Consumers agree to participate in a removal action plan along with several other companies for an area of lower Portage Creek, which is connected to the Kalamazoo River. All parties, including Consumers, that were asked to participate in the removal action plan declined to accept liability. Until further information is received from the EPA, Consumers is unable to estimate a range of potential liability for cleanup of the river.
Based on its experience, Consumers estimates that its share of the total liability for known CERCLA sites will be between $3 million and $8 million. Various factors, including the number and creditworthiness of potentially responsible parties involved with each site, affect Consumers’ share of the total liability. At December 31, 2019,2021, Consumers had a recorded liability of $3 million for its share of the total liability at these sites, the minimum amount in the range of its estimated probable CERCLA liability, as no amount in the range was considered a better estimate than any other amount.
The timing of payments related to Consumers’ remediation and other response activities at its CERCLA and NREPA sites is uncertain. Consumers periodically reviews these cost estimates. A change in the underlying assumptions, such as an increase in the number of sites, different remediation techniques, the nature and extent of contamination, and legal and regulatory requirements, could affect its estimates of NREPA and CERCLA liability.
Ludington PCB: In 1998, during routine maintenance activities, Consumers identified PCB as a component in certain paint, grout, and sealant materials at Ludington. Consumers removed part of the PCB material and replaced it with non‑PCB material. Consumers has had several communications with the EPA regarding this matter, but cannot predict the financial impact or outcome.
115

MCV PPA: In 2017, the MCV Partnership initiated arbitration against Consumers, asserting a breach of contract associated with the MCV PPA. Under this PPA, Consumers pays the MCV Partnership a fixed energy charge based on Consumers’ annual average baseload coal generating plant operating and maintenance cost, fuel inventory, and administrative and general expenses. The MCV Partnership asserts that, under the Clean Air Act, Consumers should have installed pollution control equipment on coal-fueled electric generating units years before they were retired. The MCV Partnership also asserts that Consumers should have installed pollution control equipment earlier on its remaining coal-fueled electric generating units. Additionally, the MCV Partnership claims that Consumers improperly characterized certain costs included in the calculation of the fixed energy charge.
In January 2019, an arbitration panel issued an order concluding that the MCV Partnership is not entitled to any damages associated with itsa claim against Consumers that was related to the Clean Air Act; the majority ofAct. In November 2020, the MCV Partnership’s claim, which estimated damagesPartnership and interest in excess of $270 million, was related to this dismissed claim. Consumers believes thatsigned a settlement agreement resolving all remaining disputes between the MCV Partnership’s remaining claims are without merit, but cannot predictparties, and filed the financial impact or outcome of the matter.

Underwater Cables in Straits of Mackinac: Consumers owns certain underwater electric cables in the Straits of Mackinac, which were de-energizedsettlement and retired in 1990. Consumers was notified that some of these cables were damaged as a result of vessel activity in April 2018. Following the notification, Consumers located, inspected, sampled, capped, and returned the damaged retired cables to their original location on the lake bottom, and did not find any substantive evidence of environmental contamination. After collaboratingassociated agreements with the State of Michigan, local Native American tribes,MPSC for approval. In March 2021, the MPSC approved the settlement and other stakeholders, Consumers submitted a permit application and removal work plan with EGLE and the U.S. Army Corps of Engineers in December 2019 for partial removal of all Consumers-owned cables. Upon EGLE’s issuance of a permit or certificate of coverage, which is expected in early 2020, Consumers will record an ARO for the cost to remove partially its cables, estimated to be up to $5 million. If Consumers were required to remove all the cables, it could incur costs of up to $10 million. Consumers filed suit against the companies that own the vessels that allegedly caused the damage and settled that matter.

Gas Environmental Matters: Consumers expects to incur remediation and other response activity costs at a number of sites under the NREPA. These sites include 23 former MGP facilities. Consumers operated the facilities on these sites for some part of their operating lives. For some of these sites, Consumers has no present ownership interest or may own only a portion of the original site.
At December 31, 2019,2021, Consumers had a recorded liability of $68$57 million for its remaining obligations for these sites. This amount represents the present value of long-term projected costs, using a discount rate of 2.57 percent and an inflation rate of 2.5 percent. The undiscounted amount of the remaining obligation is $73$61 million. Consumers expects to pay the following amounts for remediation and other response activity costs in each of the next five years:

Consumers periodically reviews these cost estimates. Any significant change in the underlying assumptions, such as an increase in the number of sites, changes in remediation techniques, or legal and regulatory requirements, could affect Consumers’ estimates of annual response activity costs and the MGP liability.
Pursuant to orders issued by the MPSC, Consumers defers its MGP-related remediation costs and recovers them from its customers over a ten-year period. At December 31, 2019,2021, Consumers had a regulatory asset of $130$112 million related to the MGP sites.
Consumers estimates that its liability to perform remediation and other response activities at NREPA sites other than the MGP sites could reach $3 million. At December 31, 2019,2021, Consumers had a recorded liability of less than $1 million, the minimum amount in the range of its estimated probable liability, as no amount in the range was considered a better estimate than any other amount.
Ray Compressor Station: On January 30, 2019, Consumers experienced a fire at the Ray Compressor Station, which resulted in the Ray Storage Field being off‑line or operating at significantly reduced capacity, which negatively affected Consumers’ natural gas supply and delivery capacity. This incident, which occurred during the extreme polar vortex weather condition, required Consumers to request voluntary reductions in customer load, to implement contingency gas supply purchases, and to implement


115


a curtailment of natural gas deliveries for industrial and large commercial customers pursuant to Consumers’ MPSC curtailment tariff. The curtailment and request for voluntary reductions of customer loads were canceled as of midnight, February 1, 2019. Consumers investigated the cause of the incident, and filed a report on the incident with the MPSC in April 2019. In response, the MPSC issued an order in July 2019, directing Consumers to file additional reports regarding the incident and to include detail of
116

the resulting costs in a future rate proceeding. The compressor station is presently operating at full capacity.
As a result ofIn May 2020, the fireMPSC approved an administrative settlement agreement between Consumers and the resulting curtailment, Consumers could be subject to disallowances of gas purchased and costs associatedMPSC Staff, which resulted in a $10,000 civil penalty in connection with the repairs to the Ray Compressor Station. Consumers’ incremental cost of gas purchased during the incident was $7 million. Additionally, at December 31, 2019,fire. Consumers had incurred capital expenditures of $12 million to restore the compressor station.Consumers may also be subject to various claims from impacted customers and claims for damages, or regulatory penalties. damages.
In September 2020, the MPSC disallowed the recovery of $7 million in incremental gas purchases related to the fire. In January 2021, the MPSC denied Consumers’ petition for a rehearing challenging this disallowance. In February 2021, Consumers filed an appeal of the MPSC’s denial with the Michigan Court of Appeals. Consumers could also be subject to disallowances of costs associated with the repair and modification of the Ray Compressor Station. At December 31, 2021, Consumers had incurred capital expenditures of $17 million to restore and modify the compressor station.
As of December 31, 2021, Consumers had recorded an insurance recovery of $13 million related to the compressor station. During 2021, Consumers recognized $6 million of the insurance recovery as a reduction to plant, property, and equipment, $3 million as a reduction of maintenance and other operating expenses, and $4 million as operating revenue, which represented recovery of incremental gas purchases related to the fire.
At this time, Consumers cannot predict the outcome of these matters or other gas-related incidents and a reasonable estimate of a total loss cannot be made, but they could have a material adverse effect on CMS Energy’s and Consumers’ results of operations, financial condition, or liquidity, and could subject Consumers’ gas utility to increased regulatory scrutiny.
Consumers Electric and Gas Utility Contingencies
Electric and Gas Staking: In June 2019, the MPSC ordered Consumers to show cause as to why it should not be found in violation of the MISS DIG Act. The MPSC alleges that Consumers violated the law by failing to respond in a timely manner to over 20,000 requests to mark the location of underground facilities in April and May 2019 and only partially responding to others. The law provides the MPSC with discretion in setting fines for violations, if any; however, the fines cannot exceed $5,000 per violation. Consumers resolved the backlog of staking requests, and Consumers, the MPSC Staff, and the Michigan Attorney General filed an agreement with the MPSC settling this matter for an amount of less than $1 million. The MPSC approved the settlement agreement in January 2020.

First Mortgage Bonds: Consumers secures its first mortgage bonds by a mortgage and lien on substantially all of its property. Consumers’ ability to issue first mortgage bonds is restricted by certain provisions in the First Mortgage Bond Indenture and the need for regulatory approvals under federal law. Restrictive issuance provisions in the First Mortgage Bond Indenture include achieving a 2-timestwo-times interest coverage ratio and having sufficient unfunded net property additions.
Regulatory Authorization for Financings: Consumers is required to maintain FERC authorization for financings. Its current authorization terminates on AugustJuly 31, 2021.2022. Any long-term issuances during the authorization period are exempt from FERC’s competitive bidding and negotiated placement requirements. In December 2021, Consumers filed an application for authority to issue securities between April 1, 2022 and March 31, 2024, replacing the current authorization.
Securitization Bonds: Certain regulatory assets held by Consumers’ subsidiary, Consumers 2014 Securitization Funding, collateralize Consumers’ securitization bonds. The bondholders have no recourse to Consumers’ assets except for those held by the subsidiary that issued the bonds. Consumers collects securitization surcharges to cover the principal and interest on the bonds as well as certain other qualified costs. The surcharges collected are remitted to a trustee and are not available to creditors of Consumers or creditors of Consumers’ affiliates other than the subsidiary that issued the bonds.

5:    Fair Value Measurements
125


6:Fair Value Measurements
Accounting standards define fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. When measuring fair value, CMS Energy and Consumers are required to incorporate all assumptions that market participants would use in pricing an asset or liability, including assumptions about risk. A fair value hierarchy prioritizes inputs used to measure fair value according to their observability in the market. The three levels of the fair value hierarchy are as follows:
Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities.
Level 2 inputs are observable, market-based inputs, other than Level 1 prices. Level 2 inputs may include quoted prices for similar assets or liabilities in active markets, quoted prices in inactive markets, and inputs derived from or corroborated by observable market data.
Level 3 inputs are unobservable inputs that reflect CMS Energy’s or Consumers’ own assumptions about how market participants would value their assets and liabilities.
CMS Energy and Consumers classify fair value measurements within the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement in its entirety.

Nonqualified Deferred Compensation Plan Assets and Liabilities: The nonqualified deferred compensation plan assets consist of mutual funds, which are valued using the daily quoted net asset values. CMS Energy and Consumers value their nonqualified deferred compensation plan liabilities based on the fair values of the plan assets, as they reflect the amount owed to the plan participants in accordance with their investment elections. CMS Energy and Consumers report the assets in other non‑current assets and the liabilities in other non‑current liabilities on their consolidated balance sheets.
Derivative Instruments: CMS Energy and Consumers value their derivative instruments using either a market approach that incorporates information from market transactions, or an income approach that discounts future expected cash flows to a present value amount. CMS Energy’s and Consumers’ derivatives are classified as Level 2 or Level 3.
The derivatives classified as Level 2 are interest rate swaps at CMS Energy, which are valued using market-based inputs. CMS Energy uses interest rate swaps to manage its interest rate risk on certain long‑term debt obligations and certain notes receivable at EnerBank.obligations.
In 2018, aA subsidiary of CMS Enterprises entered intouses floating-to-fixed interest rate swaps to reduce the impact of interest rate fluctuations associated with future interest payments on certain long‑term variable-rate debt. The interest rate swaps are accounted for as cash flow hedges of the future variability of interest payments on debt with a notional amount of $92$78 million at December 31, 2019.2021 and $85 million at December 31, 2020. Gains or losses on these swaps are initially reported in AOCIother comprehensive income (loss) and then, as interest payments are made on the hedged debt, are recognized in earnings within other interest expenseon long-term debt on CMS Energy’s consolidated statements of income. CMS Energy recorded losses in AOCIgains (losses) of $4 million for the year ended December 31, 2019 and $2 million for the year ended December 31, 2018.in 2021, $(6) million in 2020, and $(4) million in 2019. There were no material impacts on other

interest expenseon long-term debt associated with these swaps during the yearsperiods presented. The fair value of these swaps recorded in other liabilities on CMS Energy’s consolidated balance sheets totaled $5$4 million at December 31, 20192021 and $2$9 million at December 31, 2018.2020. CMS Energy also has other interest rate swaps that economically hedge interest rate risk on debt, but that do not qualify for cash flow hedge accounting; the amounts associated with these swaps were not material for the yearsperiods presented.
In 2019, EnerBank entered into fixed-to-floating interest rate swaps to manage interest rate risk exposure associated with changes in the fair value of certain long‑term fixed‑rate loans. The interest rate swaps qualify as fair value hedges of long‑term, fixed‑rate notes receivable with a notional amount of $134 million at December 31, 2019. The fair value of these interest rate swaps recorded in other liabilities was $1 million at December 31, 2019. CMS Energy is adjusting the carrying value of the hedged notes receivable for the change in their fair value due to the hedged risk. Both gains and losses on the swaps and the changes to the carrying value of the hedged notes receivable are recorded within operating revenue on CMS Energy’s consolidated statements of income. There were no material amounts recognized in operating revenue associated with these swaps for the year ended December 31, 2019.
The majority of derivatives classified as Level 3 are FTRs held by Consumers. Due to the lack of quoted pricing information, Consumers determines the fair value of its FTRs based on Consumers’ average historical settlements. There was no material activity within the Level 3 categories of assets and liabilities during the yearsperiods presented.

EnerBank Notes Receivable
EnerBank notes receivable are primarily unsecured consumer installment loans, largely for financing home improvements. EnerBank records its notes receivable at cost, less an allowance for loan losses. During 2019, EnerBank completed sales of notes receivable, receiving proceeds of $67 million and recording immaterial gains. At December 31, 2019, $19 million of notes receivable were classified as held for sale; the fair value of notes receivable held for sale exceeded their carrying value. These notes are expected to be sold in 2020.
During 2019, EnerBank purchased a portfolio of secured and unsecured consumer installment loans with a principal value of $373 million.
Authorized contractors pay fees to EnerBank to provide borrowers with same-as-cash, zero interest, or reduced interest loans. Unearned income associated with the loan fees, which is recorded as a reduction to notes receivable on CMS Energy’s consolidated balance sheets, was $134$7 million at December 31, 20192021 and $1022020.
5Includes current portion of long-term debt of $365 million at December 31, 2018. Unearned income associated with loan fees for notes receivable held for sale was $22021 and $364 million at December 31, 2019.
The allowance for loan losses is a valuation allowance to reflect estimated credit losses. The allowance is increased by the provision for loan losses and decreased by loan charge-offs net of recoveries. Management estimates the allowance balance required by taking into consideration historical loan loss experience, the nature and volume of the portfolio, economic conditions, and other factors. Loan losses are charged against the allowance when the loss is confirmed, but no later than the point at which a loan becomes 120 days past due.

Loans that are 30 days or more past due are considered delinquent. The balance of EnerBank’s delinquent consumer loans was $33 million at December 31, 2019 and $21 million at December 31, 2018. At December 31, 2019 and December 31, 2018, EnerBank’s loans that had been modified as troubled debt restructurings were immaterial.
EnerBank has entered into interest rate swaps on $134 million of its loans (notes receivable). For information about interest rate swaps, see Note 6, Fair Value Measurements.
DB SERP Note Receivable – Related Party

Leasehold improvements are amortized over the life of the lease, which may change whenever the lease is renewed or extended.
Capitalization: CMS Energy and Consumers record plant, property, and equipment at original cost when placed into service. The cost includes labor, material, applicable taxes, overhead such as pension and other benefits, and AFUDC, if applicable. Consumers’ plant, property, and equipment is generally recoverable through its general ratemaking process.
With the exception of utility property for which the remaining book value has been securitized, mothballed utility property stays in rate base and continues to be depreciated at the same rate as before the mothball period. When utility property is retired or otherwise disposed of in the ordinary course of business, Consumers records the original cost to accumulated depreciation, along with associated cost of removal, net of salvage. CMS Energy and Consumers recognize gains or losses on the retirement or disposal of non‑regulated assets in income. Consumers records cost of removal collected from customers, but not spent, as a regulatory liability.


133


Software: CMS Energy and Consumers capitalize the costs to purchase and develop internal-use computer software. These costs are expensed evenly over the estimated useful life of the internal-use
130

computer software. If computer software is integral to computer hardware, then its cost is capitalized and depreciated with the hardware.
AFUDC: Consumers capitalizes AFUDC on regulated major construction projects, except pollution control facilities on its fossil-fuel-fired power plants. AFUDC represents the estimated cost of debt and authorized return-on-equity funds used to finance construction additions. Consumers records the offsetting credit as a reduction of interest for the amount representing the borrowed funds component and as other income for the equity funds component on the consolidated statements of income. When construction is completed and the property is placed in service, Consumers depreciates and recovers the capitalized AFUDC from customers over the life of the related asset. Presented in the following table are Consumers’ average AFUDC capitalization rates:

Lessee
CMS Energy and Consumers lease various assets from third parties, including coal-carrying railcars, real estate, service vehicles, and gas pipeline capacity. In addition, CMS Energy and Consumers account for several of their PPAs as leases.
CMS Energy and Consumers do not record right-of-use assets or lease liabilities on their consolidated balance sheets for rentals with lease terms of 12 months or less, most of which are for the lease of real estate and service vehicles. Lease expense for these rentals is recognized on a straight-line basis over the lease term.
CMS Energy and Consumers include future payments for all renewal options, fair market value extensions, and buyout provisions reasonably certain of exercise in their measurement of lease right-of-use assets and lease liabilities. In addition, certain leases for service vehicles contain end-of-lease adjustment clauses based on proceeds received from the sale or disposition of the vehicles. CMS Energy and Consumers also include executory costs in the measurement of their right-of-use assets and lease liabilities, except for maintenance costs related to their coal-carrying railcar leases.
Most of Consumers’ PPAs contain provisions at the end of the initial contract terms to renew the agreements annually under mutually agreed‑upon terms at the time of renewal. Energy and capacity payments that vary depending on quantities delivered are recognized as variable lease costs when incurred. Consumers accounts for a PPA with one of CMS Energy’s equity method subsidiaries as a finance lease.

Consumers has an agreement to build, own, operate, and maintain a compressed natural gas fueling station through December 2038. This agreement is accounted for as a direct finance lease, under which the lessee has the option to purchase the natural gas fueling station at the end of the lease term. Fixed monthly payments escalate annually with inflation.
Beginning in December 2018, Consumers andhas a natural gas transportation agreement with a subsidiary of CMS Energy executed a 20‑year natural gas transportation agreement,that extends through 2038, related to a pipeline owned by Consumers. This agreement is accounted for as a direct finance lease and will automatically extend annually unless terminated by either party. The effects of the lease are eliminated on CMS Energy’s consolidated financial statements.
Minimum rental payments to be received under Consumers’ direct financing leases are $1 million for each of the next five years and $19$17 million for the years thereafter. The lease receivable was $10 million as of December 31, 2019,2021, which does not include unearned income of $14$12 million.
Minimum rental payments to be received under CMS Energy’s direct finance lease are less than $1 million for each of the next five years and $10$6 million for the years thereafter. The lease receivable was $5 million as of December 31, 2019,2021, which does not include unearned income of $5$4 million.
Palisades Financing
In 2007, Consumers sold Palisades to Entergy and entered into a 15-year PPA to purchase virtually all of the capacity and energy produced by Palisades, up to the annual average capacity of 798 MW. Consumers accounted for this transaction as a financing because of its continuing involvement with Palisades through security provided to Entergy for the PPA obligation and other arrangements. Palisades has therefore remained on Consumers’ consolidated balance sheets and Consumers has continued to depreciate it. At the time of the sale, Consumers recorded the sales proceeds as a financing obligation, and has subsequently recorded a portion of the payments under the PPA as interest expense and as a reduction of the financing obligation.
Total amortization and interest charges under the financing were $14 million for the years ended December 31, 2021 and 2020, and $15 million for the year ended December 31, 2019, $16 million for the year ended December 31, 2018, and $17 million for the year ended December 31, 2017.2019. At December 31, 2019,2021, the Palisades asset and financing obligation both had a balance of $29$3 million.

9:    Asset Retirement Obligations
11:Asset Retirement Obligations
CMS Energy and Consumers record the fair value of the cost to remove assets at the end of their useful lives, if there is a legal obligation to remove them. If a reasonable estimate of fair value cannot be made in the period in which the ARO is incurred, such as for assets with indeterminate lives, the liability is recognized when a reasonable estimate of fair value can be made. CMS Energy and Consumers have not recorded liabilities associated with the closure of certain gas wells that have an indeterminate life. CMS Energy and Consumers have not recorded liabilities for assets that have immaterial cumulative disposal costs, such as substation batteries.
CMS Energy and Consumers calculate the fair value of ARO liabilities using an expected present-value technique that reflects assumptions about costs and inflation, and uses a credit-adjusted risk-free rate to discount the expected cash flows. CMS Energy’s ARO liabilities are primarily at Consumers.
Presented below are the categories of assets that CMS Energy and Consumers have legal obligations to remove at the end of their useful lives and for which they have an ARO liability recorded:

10:    Retirement Benefits
12:Retirement Benefits
Benefit Plans: CMS Energy and Consumers provide pension, OPEB, and other retirement benefits to employees under a number of different plans. These plans include:
non‑contributory, qualified DB Pension Plans (closed to new non‑union participants as of July 1, 2003 and closed to new union participants as of September 1, 2005)
a non‑contributory, qualified DCCP for employees hired on or after July 1, 2003
benefits to certain management employees under a non‑contributory, nonqualified DB SERP (closed to new participants as of March 31, 2006)
a non‑contributory, nonqualified DC SERP for certain management employees hired or promoted on or after April 1, 2006
a contributory, qualified defined contribution 401(k) plan
health care and life insurance benefits under an OPEB Plan
DB Pension Plans: Participants in the pension plans include present and former employees of CMS Energy and Consumers, including certain present and former affiliates and subsidiaries. Pension plan trust assets are not distinguishable by company. Effective December 31, 2017, CMS Energy’s and Consumers’ then-existing pension plan was amended to include only retired and former employees already covered; this amended plan is referred to as DB Pension Plan B. Also effective December 31, 2017, active employees were moved to a newly created pension plan, referred to as DB Pension Plan A, whose benefits mirror those provided under DB Pension Plan B. Maintaining separate plans for the two groups allows CMS Energy and Consumers to employ a more targeted investment strategy and provides additional opportunities to mitigate risk and volatility.
In November 2021, CMS Energy and Consumers determined that 2021 lump-sum payments to retired employees under DB Pension Plan A would exceed the plan’s service cost and interest cost components of net periodic cost for the year. These lump-sum payments constitute pension plan liability settlements; once such settlements meet the service and interest cost threshold, recognition in earnings is required. As a result, in accordance with GAAP, CMS Energy, including Consumers, performed a remeasurement of DB Pension Plan A as of October 31, 2021 and recognized a settlement loss of $18 million; $18 million of this amount was recognized by Consumers and deferred as a regulatory asset. At December 31, 2021, CMS Energy, including Consumers, recognized an additional settlement loss of $4 million for the period November 1, 2021 to December 31, 2021; $3 million of this amount was recognized by Consumers and deferred as a regulatory asset. CMS Energy and Consumers will amortize the regulatory asset over eight years.
DCCP: CMS Energy and Consumers provide an employer contribution to the DCCP 401(k) plan for employees hired on or after July 1, 2003. The contribution ranges from 5 percent to 710 percent of base pay, depending on years of service.service and employee class. Employees are not required to contribute in order to receive the plan’s employer contribution. DCCP expense for CMS Energy, including Consumers, was $30$41 million for the year ended December 31, 2019, $262021, $31 million for the year ended December 31, 2018,2020, and $23$29 million for the year ended December 31, 2017.2019. DCCP expense for Consumers was $41 million for the year ended December 31, 2021, $31 million for the year ended December 31, 2020, and $28 million for the year ended December 31, 2019, $25 million for the year ended December 31, 2018, and $22 million for the year ended December 31, 2017.2019.

DB SERP: The DB SERP is a nonqualified plan as defined by the Internal Revenue Code. DB SERP benefits are paid from a rabbi trust established in 1988. The trust assets are not considered plan assets under ASC 715. DB SERP rabbi trust earnings are taxable. Presented in the following table are the fair values of trust assets, ABO, and contributions for CMS Energy’s and Consumers’ DB SERP:

DC SERP: On April 1, 2006, CMS Energy and Consumers implemented a DC SERP and froze further new participation in the DB SERP. The DC SERP provides participants benefits ranging from 5 percent to 15 percent of total compensation. The DC SERP requires a minimum of five years of participation before vesting. CMS Energy’s and Consumers’ contributions to the plan, if any, are placed in a grantor trust. For CMS Energy and Consumers, trust assets were $8$13 million at December 31, 20192021 and $5$11 million at December 31, 2018.2020. DC SERP assets are included in other non‑current assets on CMS Energy’s and Consumers’ consolidated balance sheets. CMS Energy’s and Consumers’ DC SERP expense was $2 million for the year ended December 31, 2019, and $1 million for each of the years ended December 31, 20182021, 2020, and 2017.2019.
401(k) Plan: The 401(k) plan employer match equals 100 percent of eligible contributions up to the first 3 percent of an employee’s wages and 50 percent of eligible contributions up to the next 2 percent of an employee’s wages. The total 401(k) plan cost for CMS Energy, including Consumers, was $31 million for the year ended December 31, 2021, $29 million for the year ended December 31, 2020, and $28 million for the year ended December 31, 2019,2019. The total 401(k) plan cost for Consumers was $31 million for the year ended December 31, 2021, $29 million for the year ended December 31, 2020, and $27 million for the year ended December 31, 2018, and $26 million for the year ended December 31, 2017. The total 401(k) plan cost for Consumers was $27 million for the year ended December 31, 2019, $26 million for the year ended December 31, 2018, and $25 million for the year ended December 31, 2017.2019.
OPEB Plan: Participants in the OPEB Plan include all regular full-time employees covered by the employee health care plan on the day before retirement from either CMS Energy or Consumers at age 55 or older with at least ten full years of applicable continuous service. Regular full-time employees who qualify for disability retirement under the DB Pension Plans or are disabled and covered by the DCCP and who have 15 years of applicable continuous service may also participate in the OPEB Plan. Retiree health care costs were based on the assumption that costs would increase 6.756.25 percent in 20202022 and 7.006.50 percent in 20192021 for those under 65 and would increase 7.256.75 percent in 20202022 and 7.757.00 percent in 20192021 for those over 65. The rate of increase was assumed to decline to 4.75 percent by 20272028 and thereafter for all retirees.
In 2017, CMS Energy and Consumers approved certain amendments to the OPEB Plan. Under these amendments, effective January 1, 2019, certain Medicare-eligible retirees will purchase health care plans from private Medicare exchanges. CMS Energy and Consumers performed a remeasurement of the OPEB Plan as of October 31, 2017, resulting in a significant reduction in the benefit obligation. In July 2018, CMS Energy and Consumers approved an amendment to the OPEB Plan to improve survivor benefits for certain Medicare-eligible retirees, effective January 1, 2019, resulting in a $26 million increase in the benefit obligation.

1The mortality assumption for benefit obligations was based on the Pri-2012 Mortality Table, with improvement scales MP-2021 for 2021, MP-2020 for 2020, and MP-2019 for 2019. The mortality assumption for net periodic benefit cost was based on the Pri-2012 Mortality Table for 2021 and 2020 and the RP-2014 Mortality Table for 2019, with improvement scales MP-2020 for 2021, MP-2019 for 2020, and MP-2018 for 2019.

2The discount rate reflects the rate at which benefits could be effectively settled and is equal to the equivalent single rate resulting from a yield-curve analysis. This analysis incorporated the projected benefit payments specific to CMS Energy’s and Consumers’ DB Pension Plans and OPEB Plan and the yields on high-quality corporate bonds rated Aa or better.
3CMS Energy and Consumers have elected to use a full-yield-curve approach in the estimation of service cost and interest cost; this approach applies individual spot rates along the yield curve to future projected benefit payments based on the time of payment.

The mortality assumption for benefit obligations was based on the Pri-2012 mortality table for 2019 and on the RP-2014 mortality table for 2018 and 2017, with projection scales MP-2019 for 2019, MP-2018 for 2018, and MP-2017 for 2017. The mortality assumption for net periodic benefit cost for 2019, 2018, and 2017 was based on the RP-2014 mortality table, with projection scales MP-2018 for 2019, MP-2017 for 2018, and MP-2016 for 2017.

The discount rate reflects the rate at which benefits could be effectively settled and is equal to the equivalent single rate resulting from a yield-curve analysis. This analysis incorporated the projected benefit payments specific to CMS Energy’s and Consumers’ DB Pension Plans and OPEB Plan and the yields on high-quality corporate bonds rated Aa or better.

For DB Pension Plan A, the estimated period of amortization of gains and losses was nineeight years for the years ended December 31, 20192021 and 2018.2020, and nine years for the year ended December 31, 2019. For DB Pension Plan B, the estimated period of amortization of gains and losses was 2018 years for the years ended December 31, 2019 and 2018. The estimated period of amortization for gains and losses for CMS Energy and Consumers was ten years for the DB Pension Plans for the year ended December 31, 2017.2021, 19 years for the year ended December 31, 2020, and 20 years for the year ended December 31, 2019. For the OPEB Plan, the estimated amortization period was nine years for the years ended December 31, 2021 and 2020, and ten years for the year ended December 31, 2019 and 2018 and 11 years for the year ended December 31, 2017.2019.
Prior service cost (credit) amortization is established in the year in which the prior service cost (credit) first occurred, and is based on the same amortization period for all future years until the prior service cost

(credit) is fully amortized. CMS Energy and Consumers had new prior service costs (credits) for OPEBDB Pension Plan A in 2018 and 2017.2020. The estimated period of amortization of these new prior service costs (credits) for CMS Energy and Consumers is nineeight years.
CMS Energy and Consumers determine the MRV for the assets of the DB Pension Plans as the fair value of plan assets on the measurement date, adjusted by the gains or losses that will not be admitted into the MRV until future years. CMS Energy and Consumers reflect each year’s gain or loss in the MRV in equal amounts over a five-year period beginning on the date the original amount was determined. CMS Energy and Consumers determine the MRV for OPEB Plan assets as the fair value of assets on the measurement date.

Cash and Short-Term Investments: Cash and short-term investments consist of money market funds with daily liquidity.
U.S. Government and Agencies Securities: U.S. government and agencies securities consist of U.S. Treasury notes and other debt securities backed by the U.S. government and related agencies. These securities are valued based on quoted market prices.
Corporate Debt: Corporate debt investments consist of investment grade bonds of U.S. issuers from diverse industries. These securities are valued based on quoted market prices, when available, or yields available on comparable securities of issuers with similar credit ratings.
148

State and Municipal Bonds: State and municipal bonds are valued using a matrix-pricing model that incorporates Level 2 market-based information. The fair value of the bonds is derived from various observable inputs, including benchmark yields, reported securities trades, broker/dealer quotes, bond ratings, and general information on market movements for investment grade state and municipal securities normally considered by market participants when pricing such debt securities.
Foreign Corporate Bonds: Foreign corporate debt securities are valued based on quoted market prices, when available, or on yields available on comparable securities of issuers with similar credit ratings.
Common Stocks: Common stocks in the OPEB Plan consist of equity securities that are actively managed and tracked to the S&P 500 Index. These securities are valued at their quoted closing prices.
Mutual Funds: Mutual funds represent shares in registered investment companies that are priced based on the daily quoted net asset values that are publicly available and are the basis for transactions to buy or sell shares in the funds.
Pooled Funds: Pooled funds include both common and collective trust funds as well as special funds that contain only employee benefit plan assets from two or more unrelated benefit plans. These funds primarily consist of U.S. and foreign equity securities, but also include U.S. and foreign fixed-income securities and multi-asset investments. Since these investments are valued at their net asset value as a practical expedient, they are not classified in the fair value hierarchy.

13:Stock-Based Compensation
11:    Stock-Based Compensation
CMS Energy and Consumers provide a PISP to officers, employees, and non‑employee directors based on their contributions to the successful management of the company. The PISP has a ten-year term, expiring in May 2024.2030.
In 2019,2021, all awards were in the form of restricted stock or restricted stock units. The PISP also allows for unrestricted common stock, stock options, stock appreciation rights, phantom shares, performance units, and incentive options, none of which was granted in 2019, 2018,2021, 2020, or 2017.2019.
Shares awarded or subject to stock options, phantom shares, or performance units may not exceed 6.5 million shares from June 20142020 through May 2024, nor may such awards to any recipient exceed 500,000 shares in any calendar year.2030. CMS Energy and Consumers may issue awards of up to 3,258,0005,927,297 shares of common stock under the PISP as of December 31, 2019.2021. Shares for which payment or exercise is in cash, as well as shares that expire, terminate, or are canceled or forfeited, may be awarded or granted again under the PISP.


153


All awards under the PISP vest fully upon death. Upon a change of control of CMS Energy or termination under an officer separation agreement, the awards will vest in accordance with specific officer agreements. If stated in the award, for restricted stock recipients who terminate employment due to retirement or disability, a pro-rata portion of the award will vest upon termination, with any market-based award also contingent upon the outcome of the market condition and any performance-based award contingent upon the outcome of the performance condition. The pro-rata portion is equal to the portion of the service period served between the award grant date and the employee’s termination date. The remaining portion of the awards will be forfeited. All awards for directors vest fully upon retirement. Restricted shares may be forfeited if employment terminates for any other reason or if the minimum service requirements are not met, as described in the award document.
Restricted Stock Awards: Restricted stock awards for employees under the PISP are in the form of performance-based, market-based, and time-lapse restricted stock. Award recipients receive shares of CMS Energy common stock that have dividend and voting rights. The dividends on time-lapse restricted stock are paid in cash or in CMS Energy common stock. The dividends on performance-based and market-based restricted stock are paid in restricted shares equal to the value of the dividends. These additional restricted shares are subject to the same vesting conditions as the underlying restricted stock shares.
Performance-based restricted stock vesting is contingent on meeting at least a 36-month service requirement and a performance condition. The performance condition is based on an adjusted measure of CMS Energy’s EPS growth relative to a peer group over a three-year period. The awards granted in 2019, 2018,2021, 2020, and 20172019 require a 38-month service period. Market-based restricted stock vesting is generally contingent on meeting a three-year service requirement and a market condition. The market condition is based on a comparison of CMS Energy’s total shareholder return with the median total shareholder return of a peer group over the same three-year period. Depending on the outcome of the performance condition or the market condition, a recipient may earn a total award ranging from 0zero to 200 percent of the initial grant. Time-lapse restricted stock generally vests after a service period of three years.
Restricted Stock Units: In 2019, 2018,2021, 2020, and 2017,2019, CMS Energy and Consumers granted restricted stock units to certain non‑employee directors who elected to defer their restricted stock awards. The restricted stock units generally vest after a service period of one year or, if earlier, at the next annual meeting. The restricted stock units will be distributed to the recipients as shares in accordance with the directors’ deferral agreements. Restricted stock units do not have voting rights, but do have dividend rights. In lieu of cash dividend payments, the dividends on restricted stock units are paid in additional units equal to the value of the dividends. These additional restricted stock units are subject to the same vesting and
151

distribution conditions as the underlying restricted stock units. NaNNo restricted stock units were forfeited during 2019.

CMS Energy and Consumers charge the fair value of the restricted stock awards to expense over the required service period and charge the fair value of the restricted stock units to expense immediately. For performance-based awards, CMS Energy and Consumers estimate the number of shares expected to vest at the end of the performance period based on the probable achievement of the performance objective. Performance-based and market-based restricted stock awards have graded vesting features for retirement-eligible employees, and CMS Energy and Consumers recognize expense for those awards on a graded vesting schedule over the required service period. Expense for performance-based and market-based restricted stock awards for non‑retirement-eligible employees and time-lapse awards is recognized on a straight-line basis over the required service period.
The fair value of performance-based and time-lapse restricted stock and restricted stock units is based on the price of CMS Energy’s common stock on the grant date. The fair value of market-based restricted stock awards is calculated on the grant date using a Monte Carlo simulation. CMS Energy and Consumers
152

base expected volatilities on the historical volatility of the price of CMS Energy common stock. The risk-free rate for valuation of the market-based restricted stock awards was based on the three-year U.S. Treasury yield at the award grant date.

14:Income Taxes
CMS Energy and its subsidiaries file a consolidated U.S. federal income tax return as well as a Michigan Corporate Income Tax return for the unitary business group and various other state unitary group combined income tax returns. Income taxes are allocated based on each company’s separate taxable income in accordance with the CMS Energy tax sharing agreement.
In December 2017, the TCJA was enacted, which changed existing federal tax law and included numerous provisions that affect businesses, with the primary impact being a reduction of the corporate tax rate from 35 percent to 21 percent.
Presented in the following table is the difference between actual income tax expense on continuing operations and income tax expense computed by applying the statutory U.S. federal income tax rate:

In September 2020, the MPSC authorized Consumers to accelerate the amortization of a regulatory liability associated with unprotected, nonproperty-related excess deferred income taxes resulting from the TCJA. The regulatory liability, which was previously scheduled to be amortized through 2029, will now be fully amortized by the end of 2022.

2In September 2020, the MPSC authorized Consumers to accelerate the amortization of income tax benefits associated with the cost to remove gas plant assets. These tax benefits, which were previously scheduled to be amortized through 2025, will now be fully amortized by the end of 2022.
In 2017, CMS Energy completed the evaluation of its methodology for the state apportionment of Consumers’ electricity sales to MISO, taking into account recent state tax law developments in the electric utility sector. To recognize the anticipated refund and the impact of the expected lower effective tax rate on their deferred state tax liabilities, CMS Energy, including Consumers, recorded a $14 million income tax benefit in 2017. These tax benefits were net of reserves for uncertain tax positions and primarily

attributable to Consumers. 3In 2018,March 2020, CMS Energy amendedfinalized a study of research and development tax credits for tax years 2012 through 2018. As a result, in 2020, CMS Energy, including Consumers, recognized a $9 million increase in the credit, net of reserves for uncertain tax positions. Of this amount, $8 million was recognized at Consumers.
4In January 2020, the IRS issued a decision restoring alternative minimum tax credit refunds sequestered in years prior to 2018. As a result, in 2020, CMS Energy recognized a $9 million income tax benefit for sequestered amounts related to its 2013 Michigan Corporate Income Tax return and submitted a refund claim for taxes previously paid. The refund claim was denied by the State of Michigan. In 2019,2017 tax return. CMS Energy received an unfavorable informal conference decision and filed a petition with the Michigan Tax Tribunal. A trial is anticipatedrefund in April 2020. CMS Energy’s uncertain tax position on this matter remains unchanged.

In December 2017, Consumers remeasured its deferred tax assets and liabilities at the new federal tax rate enacted by the TCJA and recorded a net $1.6 billion regulatory liability. As a result of an order received in September 2019, Consumers began refunding these excess deferred taxes to customers. For additional details on the order received, see Note 3, Regulatory Matters.
3
In 2013, the MPSC issued an order authorizing Consumers to accelerate the flow-through to electric and gas customers of certain income tax benefits associated primarily with the cost of removal of plant placed in service before 1993. Consumers implemented this regulatory treatment beginning in 2014, with the electric portion ending in 2018 and the gas portion continuing through 2025.
4
In March 2018, Consumers finalized a study of research and development tax credits for the tax years 2012 through 2016. As a result, Consumers recognized an $8 million increase in the credit, net of reserves for uncertain tax positions, at that time.
5
In December 2017, CMS Energy and Consumers recorded a reasonable estimate to measure and account for the impact of the TCJA. In December 2018, CMS Energy recorded a true-up of their estimate and eliminated the $9 million valuation allowance on the sequestration of alternative minimum tax credits.

CMS Energy has provided a valuation allowance of $2 million for the local tax loss carryforward. The TCJA repealed the corporate alternative minimum tax and requires companies to recover (through offsets of regular tax and through cash refunds) all alternative minimum tax credits over the four-year period ending in 2021. Therefore, for the year ended December 31, 2019, CMS Energy reclassified $31 million of alternative minimum tax credits to a current receivable.
CMS Energy and Consumers expect to utilize fully their tax loss and credit carryforwards for which no valuation allowance has been provided. It is reasonably possible that further adjustments will be made to the valuation allowances within one year.
In 2021, the sale of EnerBank to Regions Bank resulted in utilization of most of the federal net operating loss carryforwards. EnerBank is not included in CMS Energy’s Michigan tax filing, therefore state net operating loss carryforwards were not impacted by the sale of EnerBank.
Presented in the following table is a reconciliation of the beginning and ending amount of uncertain tax benefits:

If recognized, all of these uncertain tax benefits would affect CMS Energy’s and Consumers’ annual effective tax rates in future years. A trial is anticipated in 2022 with the Michigan Tax Tribunal related to the methodology of state apportionment for Consumers’ electricity sales to MISO; however, a final conclusion is not anticipated in the next 12 months.
CMS Energy and Consumers recognize accrued interest and penalties, where applicable, as part of income tax expense. CMS Energy, including Consumers, recognized 0no interest or penalties for each of the years ended December 31, 2019, 2018,2021, 2020, or 2017.

2019.
The amount of income taxes paid is subject to ongoing audits by federal, state, local, and foreign tax authorities, which can result in proposed assessments. CMS Energy’s federal income tax returns for 20162018 and subsequent years remain subject to examination by the IRS. CMS Energy’s Michigan Corporate Income Tax returns for 2013 and subsequent years remain subject to examination by the State of Michigan. CMS Energy’s and Consumers’ estimate of the potential outcome for any uncertain tax issue is highly judgmental. CMS Energy and Consumers believe that their accrued tax liabilities at December 31, 20192021 were adequate for all years.

Nonvested Stock Awards
CMS Energy’s nonvested stock awards are composed of participating and non‑participating securities. The participating securities accrue cash dividends when common stockholders receive dividends. Since the recipient is not required to return the dividends to CMS Energy if the recipient forfeits the award, the nonvested stock awards are considered participating securities. As such, the participating nonvested stock awards were included in the computation of basic EPS. The non‑participating securities accrue stock dividends that vest concurrently with the stock award. If the recipient forfeits the award, the stock dividends accrued on the non‑participating securities are also forfeited. Accordingly, the non‑participating
158

awards and stock dividends were included in the computation of diluted EPS, but not in the computation of basic EPS.
Forward Equity Sale Contracts
In November 2018 and February 2019, CMS Energy has entered into forward equity sale contracts. These forward equity sale contracts are non‑participating securities. While the forward sale price in the forward equity sale contract is decreased on certain dates by certain predetermined amounts to reflect expected dividend payments, these price adjustments were set upon inception of the agreement and the forward contract does not give the owner the right to participate in undistributed earnings. Accordingly, the forward equity sale contracts were included in the computation of diluted EPS, but not in the computation


162


of basic EPS. For further details on the forward equity sale contracts, see Note 5,4, Financings and Capitalization.

Electric and Gas Utilities
Consumers Utility Revenue: Consumers recognizes revenue primarily from the sale of electric and gas utility services at tariff-based rates regulated by the MPSC. Consumers’ customer base consists of a mix of residential, commercial, and diversified industrial customers. Consumers’ tariff-based sales performance obligations are described below.
Consumers has performance obligations for the service of standing ready to deliver electricity or natural gas to customers, and it satisfies these performance obligations over time. Consumers recognizes revenue at a fixed rate as it provides these services. These arrangements generally do not have fixed terms and remain in effect as long as the customer consumes the utility service. The rates are set by the MPSC through the rate-making process and represent the stand-alone selling price of Consumers’ service to stand ready to deliver.
Consumers has performance obligations for the service of delivering the commodity of electricity or natural gas to customers, and it satisfies these performance obligations upon delivery. Consumers recognizes revenue at a price per unit of electricity or natural gas delivered, based on the tariffs established by the MPSC. These arrangements generally do not have fixed terms and remain in effect as long as the customer consumes the utility service. The rates are set by the MPSC through the rate-making process and represent the stand-alone selling price of a bundled product comprising the commodity, electricity or natural gas, and the service of delivering such commodity.


162
164


In some instances, Consumers has specific fixed-term contracts with large commercial and industrial customers to provide electricity or gas at certain tariff rates or to provide gas transportation services at contracted rates. The amount of electricity and gas to be delivered under these contracts and the associated future revenue to be received are generally dependent on the customers’ needs. Accordingly, Consumers recognizes revenues at the tariff or contracted rate as electricity or gas is delivered to the customer. Consumers also has other miscellaneous contracts with customers related to pole and other property rentals, appliance service plans, and utility contract work. Generally, these contracts are short term or evergreen in nature.
Accounts Receivable and Unbilled Revenues: Accounts receivable comprise trade receivables and unbilled receivables. CMS Energy and Consumers record their accounts receivable at cost which approximates fair value.less an allowance for uncollectible accounts. The allowance is increased for uncollectible accounts expense and decreased for account write-offs net of recoveries. CMS Energy and Consumers establish anthe allowance for uncollectible accounts based on historical losses, management’s assessment of existing economic conditions, customer payment trends, and other factors.reasonable and supported forecast information. CMS Energy and Consumers assess late payment fees on trade receivables based on contractual past-due terms established with customers. Accounts are written off when deemed uncollectible, which is generally when they become six months past due.
CMS Energy and Consumers charge offrecorded uncollectible accounts deemed uncollectible to operating expense. Uncollectible expense for CMS Energy and Consumers was $29of $22 million for the year ended December 31, 20192021, $33 million for the year ended December 31, 2020, and $29 million for the year ended December 31, 2018.2019.
Consumers’ customers are billed monthly in cycles having billing dates that do not generally coincide with the end of a calendar month. This results in customers having received electricity or natural gas that they have not been billed for as of the month-end. Consumers estimates its unbilled revenues by applying an average billed rate to total unbilled deliveries for each customer class. Unbilled revenues, which are recorded as accounts receivable and accrued revenue on CMS Energy’s and Consumers’ consolidated balance sheets, were $426$486 million at December 31, 20192021 and $409$437 million at December 31, 2018.2020.
AlternativeRevenue Programs: TheConsumers accounts for its energy waste reduction incentive mechanism provides aand financial incentive if the energy savings of Consumers’ customers exceed annual targets established by the MPSC.compensation mechanism as alternative-revenue programs. Consumers accounts for this program as an alternative-revenue program that meets the criteria for recognizingrecognizes revenue related to the energy waste reduction incentive as soon as energy savings exceed the annual targets established by the MPSC.MPSC and recognizes revenue related to the financial compensation mechanism as payments are made on MPSC-approved PPAs. For additional information on these mechanisms, see Note 2, Regulatory Matters.
Under a gas revenue decoupling mechanism authorized by the MPSC, Consumers is allowed to adjust future gas rates for differences between Consumers’ actual weather‑normalized, non‑fuel revenues and the revenues approved by the MPSC. Consumers accounts for this program as an alternative‑revenue program that meets the criteria for recognizing the effects of decoupling adjustments on revenue as gas is delivered.
Consumers does not reclassify revenue from its alternative-revenue program to revenue from contracts with customers at the time the amounts are collected from customers.

Revenues to Be Refunded: In December 2020, the MPSC issued an order authorizing Consumers to refund $28 million voluntarily to utility customers. For additional information, see Note 2, Regulatory Matters.

19:Reportable Segments
17:    Reportable Segments
Reportable segments consist of business units defined by the products and services they offer. CMS Energy and Consumers evaluate the performance of each segment based on its contribution to net income available to CMS Energy’s common stockholders.
Accounting policies for CMS Energy’s and Consumers’ segments are as described in Note 1, Significant Accounting Policies.

171


these ratios change over time and are not representative of the ownership interest percentages of each membership class.
21:Variable Interest Entities
Aviator Wind Equity Holdings and Aviator Wind represent VIEs. In accordance with the associated limited liability company operating agreement, the tax equity investor is guaranteed preferred returns from Aviator Wind. However, CMS Enterprises manages and controls the operating activities of Aviator Wind Equity Holdings and, ultimately, Aviator Wind. As a result, CMS Enterprises is the primary beneficiary of Aviator Wind Equity Holdings and Aviator Wind, as it has the power to direct the activities that most significantly impact the economic performance of the companies, as well as the obligation to absorb losses or the right to receive benefits from the companies. CMS Enterprises consolidates Aviator Wind Equity Holdings and Aviator Wind and presents the Class A membership interest and 49 percent of the Class B membership interest in Aviator Wind as noncontrolling interests.

CMS Enterprises is obligated under certain indemnities that protect the tax equity investor against losses incurred as a result of breaches of representations and warranties provided by Aviator Wind Equity Holdings and its subsidiaries. For additional details on these indemnity obligations, see Note 3, Contingencies and Commitments—Guarantees.
Since Aviator Wind’s income and cash flows are not distributed among its investors based on ownership interest percentages, CMS Enterprises allocates Aviator Wind’s income (loss) among its investors by applying the hypothetical liquidation at book value method. This method calculates each investor’s earnings based on a hypothetical liquidation of Aviator Wind at the net book value of its underlying net assets as of the balance sheet date. The liquidation tax gain (loss) is allocated to each investor’s capital account, resulting in income (loss) equal to the period change in the investor’s capital account balance. CMS Enterprises then receives 51 percent of the earnings, tax attributes, and cash flows that were allocated to Aviator Wind Equity Holdings.
Other VIEs:CMS Energy has variable interests in T.E.S. Filer City, Grayling, Genesee, and Craven. While CMS Energy owns 50 percent of each partnership, it is not the primary beneficiary of any of these partnerships because decision making is shared among unrelated parties, and no one party has the ability
171

to direct the activities that most significantly impact the entities’ economic performance, such as operations and maintenance, plant dispatch, and fuel strategy. The partners must agree on all major decisions for each of the partnerships.

Enterprises
In April 2019, DIG completed a sale of transmission equipment to ITC and recognized a pre-tax gain of $16 million within maintenance and other operating expenses on CMS Energy’s consolidated statements of income.
Consumers
Asset Sale: In September 2019, Consumers completed a sale of a portion of its electric utility’s substation transmission equipment to METC. In December 2019, Consumers filed an application with the MPSC requesting approval to share voluntarily half of the gain from the sale with customers. As a result, during 2019, Consumers recorded a regulatory liability of $17 million and recognized a pre-tax gain of $17 million within maintenance and other operating expenses on its consolidated statements of income. For additional details on the sharing of the gain with customers, see Note 3, Regulatory Matters.Discontinued Operations
Exit Activities: Under its Clean Energy Plan, Consumers plans to retire the D.E. Karn 1 & 2 coal-fueled electric generating units in 2023. For additional details on Consumers’ plans to request recovery of the remaining book value of the 2 units upon their retirement, see Note 3, Regulatory Matters.
In October 2019, Consumers announced a retention incentive program to ensure necessary staffing at the D.E. Karn generating complex through the anticipated retirement of the coal-fueled electric generating units. Based on the number of employees that have chosen to participate, the aggregate cost of the program through 2023 is estimated to be $35 million.$35 million. In its order in Consumers’ 2020 electric rate case, the MPSC approved deferred accounting treatment for these costs; Consumers will seek recovery ofbegan deferring these costs from customers.
In 2019, Consumers’ electric utility recognized $6 millionas a regulatory asset in 2021. Within its 2021 IRP, Consumers proposes to retire the J.H. Campbell coal-fueled generating units. No retention incentive costs related to this retirement will be recognized unless Consumers’ 2021 IRP is approved by the MPSC.
172

As of December 31, 2021, the cumulative cost incurred and charged to expense related to the D.E. Karn retention incentive program was $16 million. Additionally, an amount of $4 million has been capitalized as a cost of plant, property, and severance benefits within maintenanceequipment and an amount of $7 million has been deferred as a regulatory asset.

Discontinued Operations: On October 1, 2021, EnerBank was acquired by Regions Bank. CMS Energy received proceeds of over $1 billion from the transaction and recognized a pre-tax gain of $657 million. CMS Energy intends to use the proceeds from the sale to fund key initiatives in its core energy business related to safety, reliability, and its clean energy transformation.
In December 2021, CMS Energy submitted a notice of disagreement to Regions Bank relating to a $36 million negative post-closing purchase price adjustment that it believes is inconsistent with the merger agreement.

Report of Independent Registered Public Accounting Firm
To the Board of Directors and Stockholders of CMS Energy Corporation
Opinions on the Financial Statements and Internal Control over Financial Reporting
We have audited the accompanying consolidated balance sheets of CMS Energy Corporation and its subsidiaries (the “Company”) as of December 31, 20192021 and 2018,2020, and the related consolidated statements of income, comprehensive income, changes in equity and cash flows for each of the three years in the period ended December 31, 2019,2021, including the related notes and financial statement schedules of CMS Energy Corporation listed in the index appearing underafter Item 15 (collectively referred to as the “consolidated financial statements”). We also have audited the Company’s internal control over financial reporting as of December 31, 2019,2021, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).
In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 20192021 and 2018,2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 20192021 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2019,2021, based on criteria established in Internal Control — Integrated Framework (2013) issued by the COSO.
Basis for Opinions
The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control Over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.
Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
Critical Audit Matters
The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.
Accounting for the Effects of New Regulatory Matters
As described in Note 32 to the consolidated financial statements, the Company is a utility and must apply regulatory accounting when its rates are designed to recover specific costs of providing regulated services. Under regulatory accounting, the Company records regulatory assets or liabilities for certain transactions that would have been treated as expense or revenue by a non-regulated business. As of December 31, 2019,2021, the Company has recognized a total of $2,522$2,305 million of regulatory assets, and $3,829$3,948 million of regulatory liabilities.liabilities, $25 million of accrued revenue, and $12 million of accrued rate refunds. As described by management, there are multiple participants to rate case proceedings who often challenge various aspects of those proceedings, including the prudence of the Company’s policies and practices. These participants often seek cost disallowances and other relief and have appealed significant decisions reached by the regulators. The recovery of regulatory assets and the settlement of regulatory liabilities are contingent upon the outcomes of rate cases and regulatory proceedings.
The principal considerations for our determination that performing procedures relating to management’s accounting for the effects of new regulatory matters is a critical audit matter are (i) there was athe high degree of auditor judgment and subjectivity applied to evaluate management’s assessment of the potential outcomes and related accounting impacts associated with pending rate case proceedings, (ii) in some cases, there wasthe significant audit effort necessary to assess contrary evidence from various parties involved in rate case proceedings, and (iii) there wasthe significant audit effort necessary to evaluate audit evidence related to the recovery of regulatory assets and the settlement of regulatory liabilities.


179
177


Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to management’s assessment of regulatory proceedings, including the probability of recovering incurred costs and the related accounting and disclosure impacts. These procedures also included, among others, obtaining and evaluating the Company’s correspondence with regulators, evaluating the reasonableness of management’s assessment regarding whether recovery of regulatory assets and settlement of regulatory liabilities is probable and evaluating the sufficiency of the disclosures in the consolidated financial statements. Procedures were performed to evaluate the regulatory assets and liabilities, including those subject to pending rate cases, based on provisions and formulas outlined in rate orders, other regulatory correspondence, or application of relevant regulatory precedents.

CMS Energy
Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures: Under the supervision and with the participation of management, including its CEO and CFO, CMS Energy conducted an evaluation of its disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act). Based on such evaluation, CMS Energy’s CEO and CFO have concluded that its disclosure controls and procedures were effective as of December 31, 2019.2021.
Management’s Annual Report on Internal Control Over Financial Reporting: CMS Energy’s management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Exchange Act Rules 13a-15(f) and 15d-15(f). CMS Energy’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP and includes policies and procedures that:
pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of CMS Energy
provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that receipts and expenditures of CMS Energy are being made only in accordance with authorizations of management and directors of CMS Energy
provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of CMS Energy’s assets that could have a material effect on its financial statements
Management, including its CEO and CFO, does not expect that its internal controls will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. In addition, any evaluation of the effectiveness of controls is subject to risks that those internal controls may become inadequate in future periods because of changes in business conditions, or that the degree of compliance with the policies or procedures deteriorates.
Under the supervision and with the participation of management, including its CEO and CFO, CMS Energy conducted an evaluation of the effectiveness of its internal control over financial reporting as of December 31, 2019.2021. In making this evaluation, management used the criteria set forth in the framework in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on such evaluation, CMS Energy’s management concluded that its internal control over financial reporting was effective as of December 31, 2019.2021.

Consumers
Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures: Under the supervision and with the participation of management, including its CEO and CFO, Consumers conducted an evaluation of its disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act). Based on such evaluation, Consumers’ CEO and CFO have concluded that its disclosure controls and procedures were effective as of December 31, 2019.2021.
Management’s Annual Report on Internal Control Over Financial Reporting: Consumers’ management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Exchange Act Rules 13a-15(f) and 15d-15(f). Consumers’ internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP and includes policies and procedures that:
pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of Consumers
provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that receipts and expenditures of Consumers are being made only in accordance with authorizations of management and directors of Consumers
provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of Consumers’ assets that could have a material effect on its financial statements
Management, including its CEO and CFO, does not expect that its internal controls will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met.

Notes to the Condensed Financial Statements
1:Basis of Presentation
1:    Basis of Presentation
CMS Energy’s condensed financial statements have been prepared on a parent-only basis. In accordance with Rule 12-04 of Regulation S-X, these parent-only financial statements do not include all of the information and notes required by GAAP for annual financial statements, and therefore these parent-only financial statements and other information included should be read in conjunction with CMS Energy’s audited consolidated financial statements contained within Item 8. Financial Statements and Supplementary Data.
2:Contingencies
Gas Index Price Reporting Litigation: CMS Energy, along with CMS MST, CMS Field Services, Cantera Natural Gas, Inc., and Cantera Gas Company, were named as defendants in 4 class action lawsuits and 1 individual lawsuit arising as a result of alleged inaccurate natural gas price reporting to publications that report trade information. Allegations include price-fixing conspiracies, restraint of trade, and artificial inflation of natural gas retail prices in Kansas, Missouri, and Wisconsin. In 2016, CMS Energy entities reached a settlement with the plaintiffs in the Kansas and Missouri class action cases for an amount that was not material to CMS Energy. In 2017, the federal district court approved the settlement.
CMS Energy and the plaintiffs in each of the Kansas and the Wisconsin actions engaged in settlement discussions and CMS Energy has recorded a $30 million liability at December 31, 2019 as a probable estimate to settle these two cases. CMS Energy can give no assurances that it can reach a final settlement with the plaintiffs in these two cases, of the actual amount CMS Energy would have to pay in any settlement, or, in the Wisconsin case, that the Wisconsin court would approve any such settlement. If settlement does not occur and the outcome after appeals is unfavorable to CMS Energy, these cases could negatively affect CMS Energy’s liquidity, financial condition, and results of operations.2:    Guarantees

3:Guarantees
