NOTE 1—GENERAL INFORMATION

Wisconsin Electric Power Company serves approximately 1.2 million electric customers and 0.5 million natural gas customers.

As used in these notes, the term "financial statements" refers to the condensed consolidated financial statements. This includes the income statements, balance sheets, statements of cash flows, and statements of equity, unless otherwise noted. In this report, when we refer to "the Company," "us," "we," "our," or "ours," we are referring to Wisconsin Electric Power Company and its subsidiary.

On our financial statements, we consolidate VIEs of which we are the primary beneficiary.

We have prepared the unaudited interim financial statements presented in this Form 10-Q pursuant to the rules and regulations of the SEC and GAAP. Accordingly, these financial statements do not include all of the information and footnotes required by GAAP for annual financial statements. These financial statements should be read in conjunction with the consolidated financial statements and footnotes in our Annual Report on Form 10-K for the year ended December 31, 2022. Financial results for an interim period may not give a true indication of results for the year. In particular, the results of operations for the three and six months ended March 31,June 30, 2023, are not necessarily indicative of expected results for 2023 due to seasonal variations and other factors.

In management's opinion, we have included all adjustments, normal and recurring in nature, necessary for a fair presentation of our financial results.

NOTE 2—ACQUISITIONS

In accordance with Topic 805: Clarifying the Definition of a Business (ASU 2017-01), transactions are evaluated and are accounted for as acquisitions of assets or businesses, and transaction costs are capitalized in asset acquisitions. It was determined that all of the below acquisitions met the criteria of an asset acquisition.

Acquisitions of Electric Generation Facilities in Wisconsin

In FebruaryJune 2023, WPS, along with an unaffiliated entity, received approval fromwe completed the PSCW to acquireacquisition of 100 MWs of West Riverside's nameplate capacity, in the first of two potential option exercises. WPS also received approval to transfer its ownership interest to us. The transaction is expected to close during the second quarter of 2023, and our investment is expected to be approximately $102 million. West Riverside is a commercially operational dual fueled combined cycle generation facility in Beloit, Wisconsin. Our investment was $95.3 million.

In January 2023, we, along with WPS, completed the acquisition of Whitewater, a commercially operational 236.5 MW dual fueled (natural gas and low sulfur fuel oil) combined cycle electric generation facility in Whitewater, Wisconsin. Our share of the cost of this facility was $38.0 million for 50% of the capacity.

NOTE 3—DISPOSITION

Sale of Real Estate

In June 2023, we sold approximately 192 acres of real estate at our former Pleasant Prairie power plant site that was no longer being utilized in our operations, for $23.0 million, which is net of closing costs. As a result of the sale, a pre-tax gain in the amount of $22.2 million was recorded within other operation and maintenance expense on our income statement. The book value of the real estate included in the sale was not material and, therefore, was not presented as held for sale.

NOTE 4—5—CREDIT LOSSES

Our exposure to credit losses is related to our accounts receivable and unbilled revenue balances, which are generated from the sale of electricity and natural gas by our regulated utility operations. Our regulated utility operations are included in our utility segment. No accounts receivable and unbilled revenue balances were reported in the other segment at March 31,June 30, 2023 and December 31, 2022.

We evaluate the collectability of our accounts receivable and unbilled revenue balances considering a combination of factors. For some of our larger customers and also in circumstances where we become aware of a specific customer's inability to meet its financial obligations to us, we record a specific allowance for credit losses against amounts due in order to reduce the net recognized receivable to the amount we reasonably believe will be collected. For all other customers, we use the accounts receivable aging method to calculate an allowance for credit losses. Using this method, we classify accounts receivable into different aging buckets and calculate a reserve percentage for each aging bucket based upon historical loss rates. The calculated reserve percentages are updated on at least an annual basis, in order to ensure recent macroeconomic, political, and regulatory trends are captured in the calculation, to the extent possible. Risks identified that we do not believe are reflected in the calculated reserve percentages, are assessed on a quarterly basis to determine whether further adjustments are required.

We monitor our ongoing credit exposure through active review of counterparty accounts receivable balances against contract terms and due dates. Our activities include timely account reconciliation, dispute resolution and payment confirmation. To the extent possible, we work with customers with past due balances to negotiate payment plans, but will disconnect customers for non-payment as allowed by the PSCW, if necessary, and employ collection agencies and legal counsel to pursue recovery of defaulted receivables. For our larger customers, detailed credit review procedures may be performed in advance of any sales being made. We sometimes require letters of credit, parental guarantees, prepayments or other forms of credit assurance from our larger customers to mitigate credit risk.

We have included a table below that shows our gross third-party receivable balances and related allowance for credit losses.

(1)Our exposure to credit losses for certain regulated utility customers is mitigated by a regulatory mechanism we have in place. Specifically, our residential tariffs include a mechanism for cost recovery or refund of uncollectible expense based on the difference between actual uncollectible write-offs and the amounts recovered in rates. As a result, at March 31,June 30, 2023, $349.7$270.4 million, or 58.7%51.4%, of our net accounts receivable and unbilled revenues balance had regulatory protections in place to mitigate the exposure to credit losses.

There was a $4.0$4.6 million increasedecrease in the allowance for credit losses at March 31,June 30, 2023, compared to January 1, 2023, driven by an increase in past due accounts receivable balances. An increase in past due balances is a trend we generally see overcustomer write-offs related to the winter moratorium months whenending. After a customer is disconnected for a period of time without payment on their account, we are not allowed to disconnectwill write off that customer service as a result of non-payment.balance. The winter moratorium begins on November 1 and ends on April 15. Also contributing to the decrease in the allowance for credit losses, we believe that the lower energy costs that customers were seeing, which were driven by lower natural gas prices, contributed to a reduction in past due accounts receivable balances and a related decrease in the allowance for credit losses.

There was a $3.8 million decrease in the allowance for credit losses at June 30, 2022, compared to January 1, 2022. The decrease was driven by customer write-offs related to collection practices returning to pre-pandemic levels in 2021, including the restoration of our ability to disconnect customers. Partially offsetting the decrease in the allowance for credit losses, we believe that the high energy costs that customers were seeing, which were driven by high natural gas prices, contributed to higher past due accounts receivable balances and a related increase in the allowance for credit losses.

NOTE 6—7—PROPERTY, PLANT, AND EQUIPMENT

Plant to be Retired

Oak Creek Power Plant Units 5 – 8

As a result of a PSCW approval for the construction of a solar and battery project received in December 2022, retirement of the OCPP generating units 5 – 8 became probable. In early 2023, WEC Energy Groupwe received additional approvals for electric generation facilities, including West Riverside and Koshkonong. See Note 2, Acquisitions, for more information on the Koshkonong Solar-Battery Park.acquisition of West Riverside, which was completed in June 2023. OCPP units 5 and 6 are expected to be retired by May 2024, while units 7 and 8 are expected to be retired by late 2025. The total net book value of our ownership share of units 5 – 8 was $812.9$808.1 million at March 31,June 30, 2023, which does not include deferred taxes. These amounts wereThis amount was classified as plant to be retired within property, plant, and equipment on our balance sheet. These units are included in rate base, and we continue to depreciate them on a straight-line basis using the composite depreciation rates approved by the PSCW.

NOTE 7—8—JOINTLY OWNED UTILITY FACILITIES

We hold joint ownership interests in certain electric generating facilities. We are entitled to our share of generating capability and output of each facility equal to our respective ownership interest. We pay our ownership share of additional construction costs and have supplied our own financing for all jointly owned projects. We record our proportionate share of significant jointly owned electric generating facilities as property, plant, and equipment on the balance sheets. In addition, our proportionate share of direct expenses for the joint operation of these plants is recorded within operating expenses in the income statements.

In January 2023, we, along with WPS, completed the acquisition of Whitewater, a commercially operational 236.5 MW dual fueled (natural gas and low sulfur fuel oil) combined cycle electrical generation facility. We own 50% of this facility. See Note 2, Acquisitions, for more information.

In June 2023, we completed the acquisition of a 13.8% ownership interest, or 100 MWs, of West Riverside, a commercially operational dual fueled combined cycle generation facility. See Note 2, Acquisitions, for more information.

In July 2023, we, along with WPS, completed the construction of a natural gas-fired generation facility at WPS's existing Weston power plant site. The new facility consists of seven RICE units. We own 50%, or 64 MWs, of the Weston RICE units. Our construction work in progress balance for the Weston RICE units was $86.1 million as of June 30, 2023.

NOTE 9—COMMON EQUITY

Various financing arrangements and regulatory requirements impose certain restrictions on our ability to transfer funds to WEC Energy Group in the form of cash dividends, loans, or advances. In addition, Wisconsin law prohibits us from making loans to or guaranteeing obligations of WEC Energy Group or its subsidiaries. See Note 10, Common Equity, in our 2022 Annual Report on Form 10-K for additional information on these and other restrictions.

We do not believe that these restrictions will materially affect our operations or limit any dividend payments in the foreseeable future.

NOTE 11—LEASES

Obligations Under Finance Leases

Land Leases – Utility Solar Generation

We, along with WPS and an unaffiliated utility, partnered to acquire and construct Darien, a utility-scale solar-powered electric generating facility with a battery energy storage system in Rock and Walworth counties, Wisconsin. We own 75% of Darien. Commercial operation of the solar portion of the project is targeted in 2024. Related to our investment in Darien, we, along with WPS and an unaffiliated utility, entered into several land leases that commenced in the second quarter of 2023. Each lease has an initial construction term that ends upon achieving commercial operation, then automatically extends for 25 years with an option for an additional 25-year extension. We expect the optional extension to be exercised, and, as a result, the land leases are being amortized over the extended term of the leases. Once Darien achieves commercial operation, the lease liability will be remeasured to reflect the final total acres being leased. The lease payments will be recovered through rates.

Our total obligation under the land-related finance leases for Darien was $33.1 million at June 30, 2023, and was included in finance lease obligations on our balance sheet. Our finance lease right of use asset related to Darien was $32.8 million as of June 30, 2023, and was included in property, plant, and equipment on our balance sheet.

In accordance with Accounting Standards Codification Subtopic 980-842, Regulated Operations – Leases (Subtopic 980-842), the expense recognition pattern associated with the Darien leases resembles that of an operating lease. The difference between the minimum lease payments and the sum of imputed interest and unadjusted amortization costs calculated under Topic 842 is deferred as a regulatory asset on our balance sheet in accordance with Subtopic 980-842.

The effective tax rates of 21.1% and 25.5% for the three and six months ended March 31,June 30, 2023 and 2022, respectively, differ from the United States statutory federal income tax rate of 21%, primarily due to state income taxes. This item was partially offset by the impact of the protected deferred tax benefits associated with the Tax Legislation, as discussed in more detail below, and PTCs.below.

The Tax Legislation required us to remeasure the deferred income taxes at our utility segment and we began to amortize the resulting excess protected deferred income taxes beginning in 2018 in accordance with normalization requirements (see federal excess deferred tax amortization linelines above).

See Note 23, Regulatory Environment, in our 2022 Annual Report on Form 10-K for more information about the impact of the Tax Legislation.

NOTE 11—14—FAIR VALUE MEASUREMENTS

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price).

Fair value accounting rules provide a fair value hierarchy that prioritizes the inputs used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). The three levels of the fair value hierarchy are defined as follows:

Level 1 – Quoted prices are available in active markets for identical assets or liabilities as of the reporting date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis.

Level 2 – Pricing inputs are observable, either directly or indirectly, but are not quoted prices included within Level 1. Level 2 includes those financial instruments that are valued using external inputs within models or other valuation methods.

03/31/06/30/2023 Form 10-Q1214Wisconsin Electric Power Company


Table of Contents
Level 3 – Pricing inputs include significant inputs that are generally less observable from objective sources. These inputs may be used with internally developed methods that result in management's best estimate of fair value. Level 3 instruments include those that may be more structured or otherwise tailored to customers' needs.

Assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. We use a mid-market pricing convention (the mid-point price between bid and ask prices) as a practical measure for valuing certain derivative assets and liabilities. We primarily use a market approach for recurring fair value measurements and attempt to use valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs.

When possible, we base the valuations of our derivative assets and liabilities on quoted prices for identical assets and liabilities in active markets. These valuations are classified in Level 1. The valuations of certain contracts not classified as Level 1 may be based on quoted market prices received from counterparties and/or observable inputs for similar instruments. Transactions valued using these inputs are classified in Level 2. Certain derivatives, such as FTRs, are categorized in Level 3 due to the significance of unobservable or internally-developed inputs. Our FTRs are valued using MISO auction prices.

The following tables summarize our financial assets and liabilities that were accounted for at fair value on a recurring basis, categorized by level within the fair value hierarchy:

NOTE 12—15—DERIVATIVE INSTRUMENTS

We use derivatives as part of our risk management program to manage the risks associated with the price volatility of purchased power, generation, and natural gas costs for the benefit of our customers. Our approach is non-speculative and designed to mitigate risk. Our regulated hedging programs are approved by the PSCW.

We record derivative instruments on our balance sheets as an asset or liability measured at fair value unless they qualify for the normal purchases and sales exception and are so designated. We continually assess our contracts designated as normal and will discontinue the treatment of these contracts as normal if the required criteria are no longer met. Changes in the derivative's fair value are recognized currently in earnings unless specific hedge accounting criteria are met or we receive regulatory treatment for the derivative. For most energy-related physical and financial contracts in our regulated operations that qualify as derivatives, the PSCW allows the effects of fair value accounting to be offset to regulatory assets and liabilities.

On our balance sheets, we classify derivative assets and liabilities as current or long-term based on the maturities of the underlying contracts. Derivative assets and liabilities not shown separately on our balance sheets are included in the other current and other long-term line items. The following table shows our derivative assets and derivative liabilities. None of the derivatives shown below are designated as hedging instruments.

03/31/2023 Form 10-Q15Wisconsin Electric Power Company


Table of Contents

Our utility segment includes our electric utility operations, including steam operations, and our natural gas utility operations.

Our electric utility operations are engaged in the generation, distribution, and sale of electricity to customers in southeastern Wisconsin (including metropolitan Milwaukee), east central Wisconsin, and northern Wisconsin. In addition, our steam operations produce, distribute, and sell steam to customers in metropolitan Milwaukee.

Our natural gas utility operations are engaged in the purchase, distribution, and sale of natural gas to retail customers as well as the transportation of customer-owned natural gas in southeastern, east central, and northern Wisconsin.

No significant items were reported in the other segment during the three and six months ended March 31,June 30, 2023 and 2022.

All of our operations and assets are located within the United States.

NOTE 16—19—VARIABLE INTEREST ENTITIES

The primary beneficiary of a VIE must consolidate the entity's assets and liabilities. In addition, certain disclosures are required for significant interest holders in VIEs.

We assess our relationships with potential VIEs, such as our coal suppliers, natural gas suppliers, coal transporters, natural gas transporters, and other counterparties related to PPAs, investments, and joint ventures. In making this assessment, we consider, along with other factors, the potential that our contracts or other arrangements provide subordinated financial support, the obligation to absorb the entity's losses, the right to receive residual returns of the entity, and the power to direct the activities that most significantly impact the entity's economic performance.

WEPCo Environmental Trust Finance I, LLC

In November 2020, the PSCW issued a financing order approving the securitization of $100 million of undepreciated environmental control costs related to our retired Pleasant Prairie power plant, the carrying costs accrued on the $100 million during the securitization process, and the related financing fees. The financing order also authorized us to form WEPCo Environmental Trust, a bankruptcy-remote special purpose entity, for the sole purpose of issuing ETBs to recover the costs approved in the financing order. WEPCo Environmental Trust is our wholly owned subsidiary.

06/30/2023 Form 10-Q18Wisconsin Electric Power Company


Table of Contents
In May 2021, WEPCo Environmental Trust issued ETBs and used the proceeds to acquire environmental control property from us. The environmental control property is recorded as a regulatory asset on our balance sheets and includes the right to impose, collect, and receive a non-bypassable environmental control charge from our retail electric distribution customers until the ETBs are paid in full and all financing costs have been recovered. The ETBs are secured by the environmental control property. Cash collections from the environmental control charge and funds on deposit in trust accounts are the sole sources of funds to satisfy the debt obligation. The bondholders have no recourse to us or any of our affiliates.

We act as the servicer of the environmental control property on behalf of WEPCo Environmental Trust and are responsible for metering, calculating, billing, and collecting the environmental control charge. As necessary, we are authorized to implement periodic adjustments of the environmental control charge. The adjustments are designed to ensure the timely payment of principal, interest, and other ongoing financing costs. We remit all collections of the environmental control charge to WEPCo Environmental Trust's indenture trustee.

WEPCo Environmental Trust is a VIE primarily because its equity capitalization is insufficient to support its operations. As described above, we have the power to direct the activities that most significantly impact WEPCo Environmental Trust's economic performance. Therefore, we are considered the primary beneficiary of WEPCo Environmental Trust, and consolidation is required.

Power Purchase Commitment

On May 31, 2022, our PPA with LSP-Whitewater Limited Partnership that represented a variable interest expired. This agreement was for 236.5 MWs of firm capacity from a natural gas-fired cogeneration facility, and we accounted for it as a finance lease.

In November 2021, we entered into a tolling agreement with LSP-Whitewater Limited Partnership that commenced on June 1, 2022, upon the expiration of the PPA. Concurrent with the execution of the tolling agreement, we, along with WPS, entered into an agreement to purchase the natural gas-fired cogeneration facility. This asset purchase agreement was approved by the PSCW in December 2022, and the acquisition closed effective January 1, 2023. In accordance with the purchase agreement, we acquired a 50% ownership interest. See Note 2, Acquisitions, for more information on the acquisition of this facility. The tolling agreement represented a variable interest until the facility was acquired since its terms were substantially similar to the terms of the PPA. Based on the risks of the entity, including operations, maintenance, dispatch, financing, fuel costs, and other factors, we were not the primary beneficiary of the entity. We did not hold an equity or debt interest in the entity, and there was no residual guarantee associated with the tolling agreement. Similar to the PPA, we accounted for the tolling agreement as a finance lease.

NOTE 17—20—COMMITMENTS AND CONTINGENCIES

We have significant commitments and contingencies arising from our operations, including those related to unconditional purchase obligations, environmental matters, and enforcement and litigation matters.

Unconditional Purchase Obligations

We have obligations to distribute and sell electricity and natural gas to our customers and expect to recover costs related to these obligations in future customer rates. In order to meet these obligations, we routinely enter into long-term purchase and sale commitments for various quantities and lengths of time. Our minimum future commitments related to these purchase obligations as of March 31,June 30, 2023, were approximately $7.9$7.6 billion.

Environmental Matters

Consistent with other companies in the energy industry, we face significant ongoing environmental compliance and remediation obligations related to current and past operations. Specific environmental issues affecting us include, but are not limited to, current and future regulation of air emissions such as sulfur dioxide, NOx, fine particulates, mercury, and GHGs; water intake and discharges; management of coal combustion products such as fly ash; and remediation of impacted properties, including former manufactured gas plant sites.

Cross State Air Pollution Rule – Good Neighbor Plan

In March 2023, the EPA issued its final Good Neighbor Plan, which requires significant reductions in ozone-forming emissions of NOx from power plants and industrial facilities. The rule tookwill take effect forin August 2023, during the latter half of the 2023 ozone season. After review of the final rule, we believe that we are well positioned to meet the requirements.

Our planned RICE units in Wisconsin are not currently subject to the final rule as each unit is less than 25 MWs. To the extent we use RICE engines for natural gas distribution operations, those engines may be subject to the emission limits and operational requirements of the rule beginning in 2026. The EPA has exempted LDCs from the final rule but included new language defining an LDC that we are still evaluating.

Mercury and Air Toxics Standards

In 2012, the EPA issued the MATS to limit emissions of mercury, acid gases, and other hazardous air pollutants. In April 2023, the EPA issued the pre-publication version of a proposed rule to strengthen and update MATS to reflect recent developments in control technologies and performance of coal and oil-fired units. The EPA proposed three revisions including a proposal to lower the PM limit from 0.03 lb/MMBtu to 0.01 lb/MMBtu, which could have an adverse effect on our utilities. The EPA is also seeking comments on an even lower limit of 0.006 lb/MMBtu. We are still evaluatingsubmitted comments to the EPA in June 2023 addressing several concerning portions of the proposed rule revisions to understand the impacts, if any, to our operations.revisions.

National Ambient Air Quality Standards

Ozone

After completing its review of the 2008 ozone standard, the EPA released a final rule in October 2015, creating a more stringent standard than the 2008 NAAQS. The 2015 ozone standard lowered the 8-hour limit for ground-level ozone. In November 2022, the EPA's 2022 CASAC Ozone Review Panel issued a draft report supporting a previously issued EPA staff-written Integrated Science Assessment for ozone which supported the reconsideration of the 2015 standard. The EPA staff issued a draft Policy Assessment in March 2023 in support of revisiting the 2020 decision to retain the 2015 ozone standards with no changes and indicated that they intend to publish their reconsideration in early 2024, with an anticipated final rule by early 2025.

In February 2022, revisions to the Wisconsin Administrative Code to adopt the 2015 standard were finalized. The amended regulations incorporated by reference the federal air pollution monitoring requirements related to the standard. The WDNR submitted the rule updates as a SIP revision to the EPA, which the EPA approved in February 2023.

In April 2022, the EPA proposed to find that the Milwaukee and Chicago, IL-IN-WI nonattainment areas did not meet the marginal attainment deadline of August 2021 and should be adjusted to "moderate" nonattainment status for the 2015 standard. In October 2022, the EPA published its final reclassifications from "marginal" to "moderate" for these areas, effective November 7, 2022. Accordingly, the WDNR was required to submitsubmitted a SIP revision to the EPA in December 2022 to address the moderate nonattainment status, which it did in December 2022.status.

We believe that we are well positioned to meet the requirements associated with the 2015 ozone standard and do not expect to incur significant costs to comply with the associated state and federal rules.

Particulate Matter

In December 2020, the EPA completed its 5-year review of the 2012 annual and 24-hour standards for fine PM and determined that no revisions were necessary to the current annual standard of 12 µg/m3 or the 24-hour standard of 35 µg/m3. Under the Biden Administration's policy review, the EPA concluded that the scientific evidence and information from the December 2020 determination supports revising the level of the annual standard for the PM NAAQS to below the current level of 12 µg/m3, while retaining the 24-hour standard. In January 2023, the EPA announced its proposed decision to revise the primary (health-based) annual PM2.5 standard from its current level of 12 µg/m3 to within the range of 9 to 10 µg/m3. The EPA also proposed not to change the current secondary (welfare-based) annual PM2.5 standard, primary and secondary 24-hour PM2.5 standards, and primary and secondary PM10 standards. The EPA is also takingdid, however, take comments on the full range (between 8 and 11 µg/m3) included in the CASAC's latest report. The EPA has announced it plans to issue aA final decision on the reconsideration is anticipated in late summer 2023. All counties within our service territory are in attainment with the current 2012 standards. If the EPA lowers the annual standard to 10 or 11 µg/m3, our generating facilities within our service territory should remain in attainment. If the EPA lowers it to below 10 µg/m3, there could be some nonattainment areas that may affect permitting of some smaller ancillary equipment located at our facilities. After finalization of the rule, the WDNR will need to draft and submit a SIP for the EPA's approval.

Climate Change

TheIn May 2023, the EPA proposed GHG performance standards for existing fossil-fired steam generating and gas combustion units and also proposed to repeal the Affordable Clean Energy rule, which replaced the Clean Power Plan, was vacated byPlan. For coal plants, there are no applicable standards until 2032, and after 2032 the D.C. Circuit Court of Appeals in January 2021. In October 2021,applicable standard is dependent on the Supreme Court agreedunit's retirement date. For combined cycle natural gas plants above a 50% capacity factor, the rule is highly dependent on hydrogen as an alternative fuel, or carbon capture. For simple cycle natural gas-fired combustion turbines, there are no applicable limits as long as the capacity factor is less than 20%. The new Weston RICE project is not affected under the rule because each RICE unit is less than 25 MWs. We are evaluating the proposed rule to reviewunderstand the D.C. Circuit Court's ruling and in June 2022, the Supreme Court issued its decision. The Supreme Court found that the EPA may regulate GHGs under section 111 of the Clean Air Act but cannot rely on generation shiftingimpacts to lower carbon emitting sources to do so. A new GHG replacement rule for existing sources is under review by the OMB.our operations.

In January 2021,May 2023, the EPA finalized a ruleproposed to revise the New Source Performance Standards for GHG emissions from new, modified, and reconstructed fossil-fueled power plants; however, it was vacatedplants. The EPA is proposing two distinct 111(b) rules – one for natural gas-fired stationary combustion turbines and the other for coal-fired units. New stationary combustion turbine units would be divided into three subcategories based on their annual capacity factor – low load, intermediate load, and base load.

WEC Energy Group continues to move forward on the ESG Progress Plan, which is heavily focused on reducing GHG emissions.

The EPA released proposed regulations for the Mandatory Greenhouse Gas Reporting Rule, 40 Code of Federal Regulations Part 98, in June 2022. In May 2023, the EPA released a supplementary proposal, which includes updates of the global warming potentials to determine CO2 equivalency for threshold reporting and the addition of a new section regarding energy consumption. The proposed revisions could impact the reporting required offor our electric generation facilities, local natural gas distribution operationscompanies, and underground natural gas storage facilities. TheIn July 2023, the EPA intendsalso issued a pre-publication version of its proposal to issue a new supplemental notice of proposed rulemaking in the second quarter of 2023amend reporting requirements for petroleum and natural gas systems, with an anticipated final rule to be issued in early 2024. We are currently evaluating the fourth quarterpotential impact, if any, of 2023 for all subparts of thisthe proposed rule.

The ESG Progress Plan includes the retirement of older, fossil-fueled generation, to be replaced with zero-carbon-emitting renewables and clean natural gas-fueled generation. We have already retired approximately 1,500 MWs of coal-firedfossil-fueled generation since the beginning of 2018. Through its ESG Progress Plan, WEC Energy Group expects to retire approximately 1,500 MWs of additional fossil-fueled generation by the end of 2026, which includes the planned retirements in 2024-2025 of OCPP Units 5-8. See Note 6,7, Property, Plant, and Equipment, for more information on the timing of the retirements. In May 2021, WEC Energy Group announced goals to achieve reductions in carbon emissions from its electric generation fleet by 60% by the end of 2025 and by 80% by the end of 2030, both from a 2005 baseline. WEC Energy Group expects to achieve these goals by making operating refinements, retiring less efficient generating units, and executing its capital plan. Over the longer term, the target for WEC Energy Group's generation fleet is net-zero CO2 emissions by 2050.

WEC Energy Group also continues to reduce methane emissions by improving its natural gas distribution systems, and has set a target across its natural gas distribution operations to achieve net-zero methane emissions by the end of 2030. WEC Energy Group

Water Quality

Clean Water Act Cooling Water Intake Structure Rule

The EPA issued a final regulation under Section 316(b) of the CWA that became effective in October 2014 and requires the location, design, construction, and capacity of cooling water intake structures at existing power plants reflect the BTA for minimizing adverse environmental impacts. The rule applies to all of our existing generating facilities with cooling water intake structures, except for the ERGS units, which were permitted and received a final BTA determination under the rules governing new facilities.

Pursuant to a WDNR rule, which became effective in June 2020, the requirements of federal Section 316(b) of the CWA were incorporated into the Wisconsin Administrative Code. The WDNR applies this rule when establishing BTA requirements for cooling water intake structures at existing facilities. These BTA requirements are incorporated into WPDES permits for our facilities.

We have received a final BTA determination for Valley power plant. We have received interim BTA determinations for PWGS and OCPP Units 5-8. We believe that existing technology installed at the OCPP facility meets the BTA requirements; however, depending on the timing of the permit reissuance, all four generating units at the OCPP may be retired prior to the WDNR making a final BTA decision, anticipated in 2025.

We are engaged in discussions with the WDNR regarding the current status of the BTA determination at PWGS. There is uncertainty about whether existing technology meets all of the WDNR's BTA requirements. We will not be in a position to determine what, if any, modifications may be needed at PWGS until the WDNR issues the WPDES permit renewal for PWGS, expected during the secondthird quarter of 2023.

As a result of past capital investments completed to address Section 316(b) compliance, we believe our fleet overall is well positioned to continue to meet this regulation.

Steam Electric Effluent Limitation Guidelines

The EPA's ELG rule, effective January 2016 and modified in 2020, revised the treatment technology requirements related to BATW and wet FGD wastewaters at existing coal-fueled facilities and created new requirements for several types of power plant wastewaters. The two new requirements that affect us relate to discharge limits for BATW and wet FGD wastewater. Although our power plant facilities already have advanced wastewater treatment technologies installed that meet many of the discharge limits established by this rule, certain facility modifications are necessary to meet the ELG rule requirements. Through 2023, we expect that compliance costs associated with the ELG rule will require $100$97 million in capital investment. A $10An $8 million BATW modification to OC 7 and OC 8 was completed and placed in-service in mid-2021, and in December 2021, the PSCW issued a Certificate of Authority approving the $90$89 million ERGS FGD wastewater treatment system modification. The BATW modifications dodid not require PSCW approval prior to construction. All of these ELG required projects are either in-service or are on track for completion by the WPDES permit deadline in December 2023.

In March 2023, the EPA issued the proposed "supplemental ELG rule." The rule would replace the existing 2020 ELG rule and, as proposed, would establish stricter limitations on: 1) BATW; 2) FGD wastewater; 3) CCR leachate; and 4) legacy wastewaters. The most significant proposed ELG rule change is a ZLD requirement for FGD wastewater. Under the proposed rule, this new ZLD requirement must be met by a date determined by the WDNR that is as soon as possible beginning 60 days following publication of the final rule, but no later than December 31, 2029.

The proposed rule would also create a subcategory for "early adopters" that have already installed a compliant biological treatment system by the date of the proposed rule (March 29, 2023).rule. Early adopters would not be required to install further FGD wastewater treatment, provided the facility owner also agrees to permanently cease combustion of coal by December 31, 2032. Although we are currently completing a $90an $89 million biological treatment system at ERGS, which we expect to be complete later this year, the expected timing of the project's completion would not comply with the deadline imposed by the EPA to qualify for early adopter status. In addition, we do not believe that, upon its completion, the biological treatment system would be compliant with the additional ZLD FGD wastewater treatment requirements as proposed. We are assessing the potential impact, as well as working with the Edison Electric Institute to submitIn May 2023, we submitted written comments to the EPA, regarding this proposed rule revision.EPA.

Waters of the United States

In January 2023, the EPA and the United States Army Corps of Engineers together released a final rule revisingeffective in March 2023, that based the definition of WOTUS. This rule became effectiveWOTUS on March 20, 2023. The final rule states that it is based on theits pre-2015 definition of "waters of the United States."definition. The pre-2015 approach involves applying factors established through case law and agency precedents to determine whether a wetland or surface drainage feature is subject to federal jurisdiction.

The recent rulemaking could be affected by a significant pending Supreme Court case involving WOTUS determination. In October 2022,May 2023, the Supreme Court heard oral arguments inissued a case,decision significantly narrowing federal jurisdiction over wetlands. In Sackett v. Environmental Protection Agency, the court ruled that the federal government's jurisdiction over WOTUS extends to evaluate the proper test for determining whether"traditional navigable waters" and wetlands are WOTUS. A decision byor other waters that have a "continuous surface connection" with a traditional navigable water.

Following the Supreme Court is expected duringdecision, the second quarteragencies announced they would interpret the definition of WOTUS consistent with the Sackett decision. The agencies are also developing a new rule to amend the definition of WOTUS that was published in the Federal Register in January 2023, to be consistent with the Sackett decision. The agencies have indicated that they intend to issue a new final rule by September 2023.

We anticipate the Sackett decision will cause a decrease in the number of projects that require Army Corps federal wetland permits. The Sackett decision may also affect the administration of some state programs. At this point, our projects requiring federal permits are moving ahead, but we are monitoring these recent developments to better understand potential future impacts. The Sackett case, once decided, should provide some clarity regarding the definition of WOTUS. We will continue to monitor this litigation and any subsequent agency action.

Manufactured Gas Plant Remediation

We have identified sites at which we or a predecessor company owned or operated a manufactured gas plant or stored manufactured gas. We have also identified other sites that may have been impacted by historical manufactured gas plant activities. We are responsible for the environmental remediation of these sites. We are also working with the state of Wisconsin in our investigation and remediation planning. These sites are at various stages of investigation, monitoring, remediation, and closure.

The future costs for detailed site investigation, future remediation, and monitoring are dependent upon several variables including, among other things, the extent of remediation, changes in technology, and changes in regulation. Historically, our regulators have allowed us to recover incurred costs, net of insurance recoveries and recoveries from potentially responsible parties, associated with the remediation of manufactured gas plant sites. Accordingly, we have established regulatory assets for costs associated with these sites.

We have established the following regulatory assets and reserves for manufactured gas plant sites:

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

CORPORATE DEVELOPMENTS

The following discussion should be read in conjunction with the accompanying unaudited financial statements and related notes and our 2022 Annual Report on Form 10-K.

Introduction

We are a wholly owned subsidiary of WEC Energy Group, and derive revenues from the distribution and sale of electricity and natural gas to retail customers in Wisconsin. We also provide wholesale electric service to numerous utilities and cooperatives for resale. We conduct our business primarily through our utility reportable segment. See Note 15,18, Segment Information, for more information on our reportable business segments.

Corporate Strategy

Our goal is to continue to build and sustain long-term value for our customers and WEC Energy Group's shareholders by focusing on the fundamentals of our business: environmental stewardship; reliability; operating efficiency; financial discipline; exceptional customer care; and safety. WEC Energy Group's capital investment plan for efficiency, sustainability and growth, referred to as its ESG Progress Plan, provides a roadmap to achieve this goal. It is an aggressive plan to cut emissions, maintain superior reliability, deliver significant savings for customers, and grow WEC Energy Group's and our investment in the future of energy.

Throughout its strategic planning process, WEC Energy Group takes into account important developments, risks and opportunities, including new technologies, customer preferences and affordability, energy resiliency efforts, and sustainability.

Creating a Sustainable Future

WEC Energy Group's ESG Progress Plan includes the retirement of older, fossil-fueled generation, to be replaced with zero-carbon-emitting renewables and clean natural gas-fired generation at its electric utilities, including us. When taken together, the retirements and new investments should better balance supply with demand, while maintaining reliable, affordable energy for our customers. The retirements will contribute to meeting WEC Energy Group's and our goals to reduce CO2 emissions from electric generation.

WEC Energy Group announced goals to achieve reductions in carbon emissions from its electric generation fleet by 60% by the end of 2025 and by 80% by the end of 2030, both from a 2005 baseline. WEC Energy Group expects to achieve these goals by making operating refinements, retiring less efficient generating units, and executing its capital plan. Over the longer term, the target for its generation fleet is net-zero CO2 emissions by 2050.

As part of the path toward these goals, we are exploring co-firing with natural gas at the ERGS coal-fired units. By the end of 2030, WEC Energy Group expects to use coal as a backup fuel only, and WEC Energy Group believes it will be in a position to eliminate coal as an energy source by the end of 2035.

WEC Energy Group already has retired more than 1,900 MWs of coal-firedfossil-fueled generation since the beginning of 2018, which included the 2019 retirement of the Presque Isle power plant as well as the 2018 retirement of the Pleasant Prairie power plant. Through the ESG Progress Plan, WEC Energy Group expects to retire approximately 1,500 MWs of additional fossil-fueled generation by the end of 2026, which includes the planned retirement in 2024-2025 of OCPP Units 5-8.

In addition to retiring these older, fossil-fueled plants, WEC Energy Group expects to invest approximately $5.4 billion from 2023-2027 in regulated renewable energy in Wisconsin. WEC Energy Group's plan is to replace a portion of the retired capacity by building and owning zero-carbon-emitting renewable generation facilities that are anticipated to include the following new investments made by either us or WPS based on specific customer needs:

1,900 MWs of utility-scale solar;
700 MWs of battery storage; and
700600 MWs of wind.

03/31/06/30/2023 Form 10-Q2326Wisconsin Electric Power Company


Table of Contents
WEC Energy Group also plans on investing in a combination of clean, natural gas-fired generation, made by either us or WPS based on specific customer needs, including:

100 MWs of RICE natural gas-fueled generation; and
including the planned purchase of up to 200100 MWs of additional capacity in West Riverside — a combined cycle natural gas plant recently completed and operated by Alliant Energy in Wisconsin.

In December 2018, we received approval from the PSCW for two renewable energy pilot programs. The Solar Now pilot is expected to add a total of 35 MWs of solar generation to our portfolio, allowing non-profit and government entities, as well as commercial and industrial customers, to site utility owned solar arrays on their property. Under this program, we have energized 25 Solar Now projects and currently have another four under construction, together totaling more than 30 MWs. The second program, the Dedicated Renewable Energy Resource (DRER)DRER pilot, would allow large commercial and industrial customers to access renewable resources that we would operate, and was adjusted down from 150 MWs tocould add up to 35 MWs of renewables that could be added to our portfolio. The DRER pilot would help these larger customers meet their sustainability and renewable energy goals. In July 2023, we received approval from the PSCW for the Renewable Pathway Pilot, the third renewable energy program. This program allows commercial and industrial customers to subscribe to a portion of a utility-scale, Wisconsin-based renewable energy generating facility. The Renewable Pathway Pilot will utilize generation from Paris and Darien and will have a participation cap of 125 MW.

In August 2021, the PSCW approved pilot programs for us to install and maintain EV charging equipment for customers at their homes or businesses. The programs provide direct benefits to customers by removing cost barriers associated with installing EV equipment. In October 2021, subject to the receipt of any necessary regulatory approvals, WEC Energy Group pledged to expand the EV charging network within its utilities' electric service territories. In doing so, WEC Energy Group joined a coalition of utility companies in a unified effort to make EV charging convenient and widely available throughout the Midwest. The coalition WEC Energy Group joined is planning to help build and grow EV charging corridors, enabling the general public to safely and efficiently charge their vehicles.

WEC Energy Group also continues to reduce methane emissions by improving its natural gas distribution system, and has set a target across its natural gas distribution operations to achieve net-zero methane emissions by the end of 2030. WEC Energy Group plans to achieve its net-zero goal through an effort that includes both continuous operational improvements and equipment upgrades, as well as the use of RNG throughout its natural gas utility systems. In 2022, we received approval from the PSCW for an RNG pilot associated with our natural gas distribution system.

WEC Energy Group isWe are planning for the start of a pilot program forin the fourth-quarter of 2023 with the Electric Power Research Institute and CMBlu Energy, a Germany-based designer and manufacturer, to test a new form of long-duration energy storage on the U.S. electric grid. The program will test battery system performance, including the ability to store and discharge energy for up to twice as long as the typical lithium-ion batteries in use today.

Reliability

We have made significant reliability-related investments in recent years, and in accordance with the ESG Progress Plan, expect to continue strengthening and modernizing our generation fleet, as well as our electric and natural gas distribution networks to further improve reliability.

We received approval to construct an LNG facility to meet anticipated peak demand. Commercial operation of the LNG facility is targeted for the end of 2023.

For more details, see Liquidity and Capital Resources – Cash Requirements – Significant Capital Projects.

Operating Efficiency

We continually look for ways to optimize the operating efficiency of our company and will continue to do so under the ESG Progress Plan. For example, we are making progress on our AMI program, replacing aging meter-reading equipment on both our network and customer property. An integrated system of smart meters, communication networks, and data management programs enables two-way communication between us and our customers. This program reduces the manual effort for disconnects and reconnects and enhances outage management capabilities.

Financial Discipline

A strong adherence to financial discipline is essential to meeting our earnings projections and maintaining a strong balance sheet, stable cash flows, and quality credit ratings.

We follow an asset management strategy that focuses on investing in and acquiring assets consistent with our strategic plans, as well as disposing of assets, including property, plants, and equipment, that are no longer strategic to operations, are not performing as intended, or have an unacceptable risk profile. See Note 2, Acquisitions, for more information on our acquisitionacquisitions of Whitewater and pending acquisition of West Riverside. See Note 3, Disposition, for information on a recent transaction.

Exceptional Customer Care

Our approach is driven by an intense focus on delivering exceptional customer care every day. We strive to provide the best value for our customers by demonstrating personal responsibility for results, leveraging our capabilities and expertise, and using creative solutions to meet or exceed our customers’ expectations.

A multiyear effort is driving a standardized, seamless approach to digital customer service across all of the WEC Energy Group companies. It has moved all utilities, including us, to a common platform for all customer-facing self-service options. Using common systems and processes reduces costs, provides greater flexibility and enhances the consistent delivery of exceptional service to customers.

Safety

Safety is one of our core values and a critical component of our culture. We are committed to keeping our employees and the public safe through a comprehensive corporate safety program that focuses on employee engagement and elimination of at-risk behaviors.

Under our "Target Zero" mission, we have an ultimate goal of zero incidents, accidents, and injuries. Management and union leadership work together to reinforce the Target Zero culture. We set annual goals for safety results as well as measurable leading indicators, in order to raise awareness of at-risk behaviors and situations and guide injury-prevention activities. All employees are encouraged to report unsafe conditions or incidents that could have led to an injury. Injuries and tasks with high levels of risk are assessed, and findings and best practices are shared across the WEC Energy Group companies.

Our corporate safety program provides a forum for addressing employee concerns, training employees and contractors on current safety standards, and recognizing those who demonstrate a safety focus.

Non-GAAP Financial Measures

The discussion below addresses the contribution of our utility segment to net income attributed to common shareholder. The discussion includes financial information prepared in accordance with GAAP, as well as electric margins and natural gas margins, which are not measures of financial performance under GAAP. Electric margins (electric revenues less fuel and purchased power costs) and natural gas margins (natural gas revenues less cost of natural gas sold) are non-GAAP financial measures because they exclude other operation and maintenance expense, depreciation and amortization, and property and revenue taxes.

We believe that electric and natural gas margins provide a useful basis for evaluating utility operations since the majority of prudently incurred fuel and purchased power costs, as well as prudently incurred natural gas costs, are passed through to customers

in current rates. As a result, management uses electric and natural gas margins internally when assessing the operating performance of our utility segment as these measures exclude the majority of revenue fluctuations caused by changes in these expenses. Similarly, the presentation of electric and natural gas margins herein is intended to provide supplemental information for investors regarding our operating performance.

Our electric margins and natural gas margins may not be comparable to similar measures presented by other companies. Furthermore, these measures are not intended to replace operating income as determined in accordance with GAAP as an indicator of operating performance. Our utility segment operating income for the three months ended June 30, 2023 and 2022 was $244.1 million and $206.5 million, respectively.

Electric Revenues

Electric revenues decreased $17.2 million during the second quarter of 2023, compared with the same quarter in 2022. To the extent that changes in fuel and purchased power costs are passed through to customers, the changes are offset by comparable changes in revenues. See the discussion of electric utility margins below for more information related to the recovery of fuel and purchased power costs and the remaining drivers of the changes in electric revenues.

Electric Utility Margins

Electric utility margins increased $44.5 million during the second quarter of 2023, compared with the same quarter in 2022. The significant factors impacting the higher electric utility margins were:

A $57.3 million increase in margins related to the impact of our rate order approved by the PSCW, effective January 1, 2023. See Note 23, Regulatory Environment, in our 2022 Annual Report on Form 10-K for more information on the 2023 rate order.

A $7.5 million quarter-over-quarter positive impact from collections of fuel and purchased power costs. Under the Wisconsin fuel rules, our margins are impacted by under- or over-collections of certain fuel and purchased power costs that are within a 2% price variance from the costs included in rates, and the remaining variance beyond the 2% price variance is generally deferred for future recovery or refund to customers.

A $5.0 million decrease in expense during the second quarter of 2023, related to the expiration of a capacity contract driven by the acquisition of the Whitewater facility, effective January 1, 2023.

These increases in margins were partially offset by:

A $17.5 million decrease in margins related to lower sales volumes, driven by the impact of cooler spring weather during the second quarter of 2023, compared with the same quarter in 2022. As measured by cooling degree days, the second quarter of 2023 was 39.0% cooler than the same quarter in 2022.

A $5.6 million decrease in other revenues, primarily related to third-party use of our assets and a FERC order in January 2023 that eliminated reactive power compensation MISO was required to pay to generators, including us.

Natural Gas Revenues

Natural gas revenues decreased $26.0 million during the second quarter of 2023, compared with the same quarter in 2022. Because prudently incurred natural gas costs are passed through to our customers in current rates, the changes are offset by comparable changes in revenues. The average per-unit cost of natural gas decreased 47% during the second quarter of 2023, compared with the same quarter in 2022. The remaining drivers of changes in natural gas revenues are described in the discussion of natural gas utility margins below.

Natural Gas Utility Margins

Natural gas utility margins increased $5.3 million during the second quarter of 2023, compared with the same quarter in 2022. The most significant factor impacting the higher natural gas utility margins was a $7.4 million increase in margins related to the impact of our rate order approved by the PSCW, effective January 1, 2023. This increase in margins was partially offset by a $1.8 million decrease in margins from lower sales volumes, driven by warmer weather during the second quarter of 2023, compared with the same quarter in 2022. As measured by heating degree days, the second quarter of 2023 was 9.8% warmer than the same quarter in 2022. See Note 23, Regulatory Environment, in our 2022 Annual Report on Form 10-K for more information on the 2023 rate order.

Other Operating Expenses (includes other operation and maintenance, depreciation and amortization, and property and revenue taxes)

Other operating expenses at the utility segment increased $12.2 million during the second quarter of 2023, compared with the same quarter in 2022. The significant factors impacting the increase in other operating expenses were:

An $18.9 million increase in transmission expense as approved in the PSCW's 2023 rate order, effective January 1, 2023. See the notes under the other operation and maintenance table above for more information. This amount is net of a deferral of $2.8 million approved by the PSCW in June 2023, retroactive to December 1, 2022, in response to a FERC order eliminating reactive power compensation to our utilities, as discussed in electric margins above.

A $9.6 million increase in depreciation and amortization, driven by assets being placed into service as we continue to execute on our capital plan.

06/30/2023 Form 10-Q31Wisconsin Electric Power Company


Table of Contents
An $8.2 million increase in other operation and maintenance expense related to the We Power leases, as discussed in the notes under the other operation and maintenance table above.

A $7.6 million increase in regulatory amortizations and other pass through expenses, as discussed in the notes under the other operation and maintenance table above.

These increases in other operating expenses were partially offset by:

A $22.2 million pre-tax gain on the sale of land at our Pleasant Prairie power plant site during the second quarter of 2023. See Note 3, Disposition, for more information.

A $9.3 million decrease in benefit costs, primarily driven by lower stock-based compensation and incentive costs, partially offset by an increase in deferred compensation costs.

Other Income, Net

Other income, net increased $7.6 million during the second quarter of 2023, compared with the same quarter in 2022, driven by higher AFUDC–Equity due to continued capital investment.

Interest Expense

Interest expense increased $3.8 million during the second quarter of 2023, compared with the same quarter in 2022, driven by the impact of a $500.0 million long-term debt issuance in September 2022 and higher short-term debt interest rates. These increases were partially offset by higher AFUDC–Debt due to continued capital investment. Lower interest expense on finance lease liabilities, primarily related to the We Power leases, as finance lease liabilities decrease each year as payments are made, also contributed to the offset in interest expense.

Income Tax Expense

Income tax expense increased $7.6 million during the second quarter of 2023, compared with the same quarter in 2022, driven by higher pre-tax income, partially offset by a $1.4 million increase in PTCs.

SIX MONTHS ENDED JUNE 30, 2023

Earnings

Our earnings for the six months ended June 30, 2023 were $233.3 million, compared to $216.3 million for the same period in 2022. See below for information on the $17.0 million increase in earnings.

Expected 2023 Annual Effective Tax Rate

We expect our 2023 annual effective tax rate to be between 22.0% and 23.0%. Our effective tax rate calculations are revised every quarter based on the best available year-end tax assumptions, adjusted in the following year after returns are filed. Tax accrual estimates are trued-up to the actual amounts claimed on the tax returns and further adjusted after examinations by taxing authorities, as needed.

A $117.6 million increase in margins related to the impact of our rate order approved by the PSCW, effective January 1, 2023. See Note 23, Regulatory Environment, in our 2022 Annual Report on Form 10-K for more information on the 2023 rate order.

This increaseAn $11.5 million decrease in expense during the six months ended June 30, 2023, related to the expiration of a capacity contract driven by the acquisition of the Whitewater facility, effective January 1, 2023.

These increases in margins waswere partially offset by:

A $29.3$36.2 million quarter-over-quarterdecrease in margins related to lower sales volumes, driven by the impact of unfavorable weather during the six months ended June 30, 2023, compared with the same period in 2022. As measured by cooling degree days, the six months ended June 30, 2023 were 39.0% cooler than the same period in 2022. As measured by heating degree days, the six months ended June 30, 2023 were 13.8% warmer than the same period in 2022.

A $21.8 million period-over-period negative impact from collections of fuel and purchased power costs compared with costs collected in rates.costs. Under the Wisconsin fuel rules, our margins are impacted by under- or over-collections of certain fuel and purchased power costs that are within a 2% price variance from the costs included in rates, and the remaining variance beyond the 2% price variance is generally deferred for future recovery or refund to customers.

An $18.0 million decrease in margins related to lower sales volumes, driven by the impact of warmer winter weather during the first quarter of 2023, compared with the same quarter in 2022. As measured by heating degree days, the first quarter of 2023 was 14.8% warmer than the same quarter in 2022.

Lower margins of $6.0$8.3 million driven by the expiration of a wholesale contract.contract in May 2022.

A $7.0 million decrease in other revenues, primarily related to third-party use of our assets and a FERC order in January 2023 that eliminated reactive power compensation MISO was required to pay to generators, including us.

A $3.8 million decrease in margins from our steam operations driven by lower sales volumes, including the impact of weather.

Natural Gas Revenues

Natural gas revenues increased $7.7decreased $18.3 million during the first quarter ofsix months ended June 30, 2023, compared with the same quarterperiod in 2022. Because prudently incurred natural gas costs are passed through to our customers in current rates, the changes are offset by comparable changes in revenues. The average per-unit cost of natural gas increased 9% during the first quarter of 2023, compared with the same quarter in 2022. The remaining drivers of changes in natural gas revenues are described in the discussion of natural gas utility margins below.

Natural Gas Utility Margins

Natural gas utility margins increased $14.4$19.7 million during the first quarter ofsix months ended June 30, 2023, compared with the same quarterperiod in 2022. The most significant factor impacting the higher natural gas utility margins was a $22.6$28.9 million increase in margins related to the impact of our rate order approved by the PSCW, effective January 1, 2023. This increase in margins was partially offset by a $7.1$9.2 million decrease in margins from lower sales volumes, driven by warmer winter weather during the first quarter ofsix months ended June 30, 2023, compared with the same quarterperiod in 2022.

Other Operating Expenses (includes other operation and maintenance, depreciation and amortization, and property and revenue taxes)

Other operating expenses at the utility segment increased $51.3$63.5 million during the first quarter ofsix months ended June 30, 2023, compared with the same quarterperiod in 2022. The significant factors impacting the increase in other operating expenses were:

A $21.7$40.6 million increase in transmission expense as approved in ourthe PSCW's 2023 rate order, effective January 1, 2023. See the notes under the other operation and maintenance table above for more information. This amount is net of a deferral of $2.8 million approved by the PSCW in June 2023, retroactive to December 1, 2022, in response to a FERC order eliminating reactive power compensation, as discussed in electric margins above.

An $8.7$18.3 million increase in depreciation and amortization, driven by assets being placed into service as we continue to execute on our capital plan.

A $7.9 million increase in regulatory amortizations and other pass through expenses, as discussed in the notes under the other operation and maintenance table above.

A $7.9$16.1 million increase in other operation and maintenance expense related to the We Power leases, as discussed in the notes under the other operation and maintenance table above.

A $15.5 million increase in regulatory amortizations and other pass through expenses, as discussed in the notes under the other operation and maintenance table above.

These increases in other operating expenses were partially offset by:

A $22.2 million pre-tax gain on the sale of land at our Pleasant Prairie power plant site during the six months ended June 30, 2023. See Note 3, Disposition, for more information.

A $6.8 million decrease in benefit costs, primarily driven by lower stock-based compensation and incentive costs, partially offset by an increase in deferred compensation costs.

Other Income, Net

Other income, net increased $4.5$12.1 million during the first quarter ofsix months ended June 30, 2023, compared with the same quarterperiod in 2022, driven by higher AFUDC–Equity due to continued capital investment. This increase was partially offset by lower net credits from the non-service components of our net periodic pension and OPEB costs. See Note 14, Employee Benefits, for more information on our benefit costs.

Interest Expense

Interest expense increased $4.4$8.2 million during the first quarter ofsix months ended June 30, 2023, compared with the same quarterperiod in 2022, driven byprimarily due to the impact of a $500.0 million long-term debt issuance in September 2022 and higher short-term debt interest rates. These increases were partially offset by higher AFUDC-DebtAFUDC–Debt due to continued capital investment. Lower interest expense on finance lease liabilities, primarily related to the We Power leases, as finance lease liabilities decrease each year as payments are made, also contributed to the offset in interest expense.

Income Tax Expense

Income tax expense decreased $14.8$7.2 million during the first quarter ofsix months ended June 30, 2023, compared with the same quarterperiod in 2022, driven by lower pre-tax income and a $4.6$6.0 million increase in PTCs.

The new facility will consistconsists of seven RICE units. Once constructed, we willWe own 64 MWs of this project. Our shareconstruction work in progress balance for the Weston RICE units was $86.1 million as of the cost of this project is estimated to be approximately $85 million, with construction expected to be completed inJune 30, 2023.

In January 2023, we, along with WPS, completed the acquisition of Whitewater, a commercially operational 236.5 MW dual fueled (natural gas and low sulfur fuel oil) combined cycle electrical generation facility in Whitewater, Wisconsin. Our share of the cost of this facility was $38.0 million for 50% of the capacity.

In FebruaryJune 2023, WPS, along with an unaffiliated utility, received PSCW approval to acquire a portionwe closed on the purchase of West Riverside's nameplate capacity. WPS also received approval to assign the option to purchase part of West Riverside to us. We will acquire 100 MWs of capacity in the first of two potential option exercises.related to West Riverside for $95.3 million. West Riverside is a combined cycle natural gas plant recently completed and operated by an unaffiliated utility in Rock County, Wisconsin. Our share of the cost of this ownership interest is expected to be approximately $102 million, with the transaction expected to close in the second quarter of 2023. In addition, WPS could exercise and request approval to assign to us a second option to acquire an additional 100 MWs of capacity. If approved, and WPS assigns the option to us, our share of the cost of this ownership interest is expected to be approximately $100 million, with the transaction expected to close in 2024.

In March 2022, the DOC opened an investigation into whether new tariffs should be imposed on solar panels and cells imported from multiple southeast Asian countries. See Factors Affecting Results, Liquidity, and Capital Resources – Regulatory, Legislative, and Legal Matters – United States Department of Commerce Complaint and Factors Affecting Results, Liquidity, and Capital Resources – Regulatory, Legislative, and Legal Matters – Uyghur Forced Labor Prevention Act for information on the potential impacts to our solar projects as a result of the DOC investigation and CBP actions related to solar panels, respectively. The expected in-service dates and costs identified above already reflect some of these impacts.

We have received PSCW approval to construct ana LNG facility. The facility would provide us with approximately one billion cubic feet of natural gas supply to meet anticipated peak demand without requiring the construction of additional interstate pipeline capacity. The facility is expected to reduce the likelihood of constraints on our natural gas system during the highest demand days of winter. The project is estimated to cost approximately $185 million. Commercial operation of the LNG facility is targeted for the end of 2023.

Sources of Cash

Liquidity

We anticipate meeting our short-term and long-term cash requirements to operate our business and implement our corporate strategy through internal generation of cash from operations, equity contributions from our parent, and access to the capital markets, which allows us to obtain external short-term borrowings, including commercial paper, and intermediate or long-term debt securities. Cash generated from operations is primarily driven by sales of electricity and natural gas to our utility customers, reduced by costs of operations. Our access to the capital markets is critical to our overall strategic plan and allows us to supplement cash flows from operations with external borrowings to manage seasonal variations, working capital needs, commodity price fluctuations, unplanned expenses, and unanticipated events.

We maintain a bank back-up credit facility, which provides liquidity support for our obligations with respect to commercial paper and for general corporate purposes. We review our bank back-up credit facility needs on an ongoing basis and expect to be able to maintain adequate credit facilities to support our operations.

The amount, type, and timing of any financings for the remainder of 2023, as well as in subsequent years, will be contingent on investment opportunities and our cash requirements and will depend upon prevailing market conditions, regulatory approvals, and other factors. We plan to maintain a capital structure consistent with that approved by the PSCW. For more information on our approved capital structure, see Item 1. Business – C. Regulation in our 2022 Annual Report on Form 10-K.

The issuance of our securities is subject to the approval of the PSCW. Additionally, with respect to the public offering of securities, we file registration statements with the SEC under the Securities Act of 1933, as amended (1933 Act). The amounts of securities authorized by the PSCW, as well as the securities registered under the 1933 Act, are closely monitored and appropriate filings are made to ensure flexibility in the capital markets.

Although not the case as of March 31,June 30, 2023, our current liabilities sometimes exceed our current assets. If this occurs, we do not expect that it would have any impact on our liquidity, as we currently believe that our cash and cash equivalents, our available capacity of $371.5$456.0 million under our existing revolving credit facility, cash generated from ongoing operations, and access to the capital markets are adequate to meet our short-term and long-term cash requirements.

These trusts had investments consisting of fixed income and equity securities that are subject to the volatility of the stock market and interest rates. For more information, see Investments in Outside Trusts in Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations – Liquidity and Capital Resources – Sources of Cash in our 2022 Annual Report on Form 10-K.

Debt Covenants

Certain of our short-term debt agreements contain financial covenants that we must satisfy, including a debt to capitalization ratio. At March 31,June 30, 2023, we were in compliance with all such covenants. We expect to be in compliance with all such debt covenants for the foreseeable future. See Note 12, Short-Term Debt and Lines of Credit, Note 13, Long-Term Debt, and Note 10, Common Equity, in our 2022 Annual Report on Form 10-K, for more information regarding our debt covenants.

Credit Rating Risk

Cash collateral postings and prepayments made with external parties, including postings related to exchange-traded contracts, and cash collateral posted by external parties were immaterial as of March 31,June 30, 2023. From time to time, we may enter into commodity contracts that could require collateral or a termination payment in the event of a credit rating change to below BBB- at S&P Global Ratings, a division of S&P Global Inc., and/or Baa3 at Moody’s Investors Service, Inc. If we had a sub-investment grade credit rating at March 31,June 30, 2023, we could have been required to post $100 million of additional collateral or other assurances pursuant to the

terms of a PPA. We also have other commodity contracts that, in the event of a credit rating downgrade, could result in a reduction of our unsecured credit granted by counterparties.

In addition, access to capital markets at a reasonable cost is determined in large part by credit quality. Any credit ratings downgrade could impact our ability to access capital markets.

Subject to other factors affecting the credit markets as a whole, we believe our current ratings should provide a significant degree of flexibility in obtaining funds on competitive terms. However, these security ratings reflect the views of the rating agency only. An explanation of the significance of these ratings may be obtained from the rating agency.

The following is a discussion of certain factors that may affect our results of operations, liquidity, and capital resources. This discussion should be read together with the information in Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations – Factors Affecting Results, Liquidity, and Capital Resources in our 2022 Annual Report on Form 10-K, which provides a more complete discussion of factors affecting us, including market risks and other significant risks, competitive markets, environmental matters, critical accounting policies and estimates, and other matters.

Regulatory, Legislative, and Legal Matters

Petitions Before PSCW Regarding Third-Party Financed Distributed Energy Resources

In May 2022, two petitions were filed with the PSCW requesting a declaratory ruling that the owner of a third-party financed DER is not a "public utility" as defined under Wisconsin law and, therefore, is not subject to the PSCW’s jurisdiction under any statute or rule regulating public utilities. The parties that filed the petitions provide financing to their customers for installation of DERs (including solar panels and energy storage) on the customer’s property. A DER is connected to the host customer’s utility meter and is used for the customer’s energy needs. It may also be connected to the grid for distribution.

In July 2022, the PSCW found that the specific facts and circumstances merited the opening of a docket for each petition to consider whether to grant all or part of the requested declaratory ruling.

OnIn December 1, 2022, the PSCW granted one petitioner’s request for a declaratory ruling, finding that the owner of the third-party financed DER at issue in the petitioner’s brief is not a public utility under Wisconsin law. The ruling was limited to the specific facts and circumstances of the lease presented in that petition. A recent petition by several utilitiesthe WUA to reopen or rehear the case expired without action by the PSCW. The WUA has filed an appeal which is pending consideration by the circuit court. The second petition is also currently being considered. Although the finding in the first petition was limited to the specific facts and circumstances of the lease presented in that petition, similar findings or a broader policy position could adversely impact our business operations.

Uyghur Forced Labor Prevention Act

The CBP issued a WRO in June 2021, applicable to certain silica-based products originating from the Xinjiang Uyghur Autonomous Region of China (Xinjiang), such as polysilicon, included in the manufacturing of solar panels. In June 2022, the WRO was superseded by the implementation of the UFLPA, which was signed into law by President Biden in December 2021. The UFLPA establishes a rebuttable presumption that any imports wholly or partially manufactured in Xinjiang are prohibited from entering the United States. While our suppliers were able to provide the CBP sufficient documentation to meet WRO compliance requirements, and we expect the same will be true for UFLPA purposes, we cannot currently predict what, if any, long-term impact the UFLPA will have on the overall supply of solar panels into the United States and the related long-term impact to timing and cost of our solar projects included in WEC Energy Group's capital plan. However, we are seeing some delays in the release of solar panels by the CBP, which are having an impact on the timing and cost of certain of our solar projects.

United States Department of Commerce ComplaintComplaints

In February 2022, a California based company filed a petition (AD/CVD)(Antidumping and Countervailing Duties) with the DOC seeking to impose new tariffs on solar panels and cells imported from multiple countries, including Malaysia, Vietnam, Thailand, and Cambodia. The petitioners claimed that Chinese solar manufacturers are shifting products to these countries to avoid the tariffs required on products imported from China

and requested that the DOC conduct a country-wide inquiry into each of the four countries. In March 2022, the DOC decided to actAfter investigation, on the petition and investigate the claim. On December 2, 2022, the DOC announced its preliminary determination that certain companies are circumventing anti-dumping and countervailing duty orders on solar cells and modules from China. If the DOC makes aA final determination, whichdecision is currently expected in the secondthird quarter of 2023,2023. If the DOC determines that such circumvention is occurring it would be able to apply any final tariffs retroactively to November 4, 2021. If imposed, the new tariffs could further disrupt the supply of solar modules to the United States, and could impact the cost and timing of our solar projects.

InTo address concerns raised about the adverse impact from the ongoing DOC complaint on the U.S. solar industry, in June 2022, the Biden Administration used its executive powers to issue a 24-month tariff moratorium on solar panels manufactured in Cambodia, Malaysia, Thailand, and Vietnam. The moratorium comes as a direct response to concerns raised aboutIn May 2023, the adverse impact fromBiden Administration vetoed legislation that would have repealed the ongoing DOC complaint on the U.S. solar industry. As the DOC will continue its investigation discussed above, companiesmoratorium. Companies may still be subject to tariffs after the moratorium ends; however, U.S. companies will reportedly be exempt from any retroactive tariffs that previously could have applied. TheAdditionally, the Biden Administration also announced that it plans to invokeinvoked the Defense Production Act to accelerate the production of solar panels in the U.S. The Biden Administration's actions did not address whether WROs applied to panels under previous complaints would be affected.

Infrastructure Investment and Jobs Act

In November 2021, President Biden signed into law the Infrastructure Investment and Jobs Act, which provides for approximately $1.2 trillion of federal spending over the next five years, including approximately $85 billion for investments in power, utilities, and renewables infrastructure across the United States. We expect funding from this Act will support the work we are doing to reduce GHG emissions, increase EV charging, and strengthen and protect the energy grid. Funding in the Act should also help to expand emerging technologies, like hydrogen and carbon management, as we continue the transition to a clean energy future. We believe the Infrastructure Investment and Jobs Act will accelerate investment in projects that will help us meet our net zero emission goals to the benefit of our customers, the communities we serve, and our company.

Inflation Reduction Act

In August 2022, President Biden signed into law the IRA, which provides for $258 billion in energy-related provisions over a 10-year period. The provisions of the IRA are intended to, among other things, lower gasoline and electricity prices, incentivize domestic

clean energy investment, manufacturing, and production, and promote reductions in carbon emissions. We believe that we and our customers can benefit from the IRA’s provisions that extend tax benefits for renewable technologies, increase or restore higher rates for PTCs, add an option to claim PTCs for solar projects, expand qualified ITC facilities to include standalone energy storage, and its provision to allow companies to transfer tax credits generated from renewable projects. The IRA also implements a 15% corporate alternative minimum tax and a 1% excise tax on stock repurchases. Although significant regulatory guidance is expected on the tax provisions in the IRA, we currently believe the provisions on alternative minimum tax and stock repurchases will not have a material impact on us. Overall, we believe the IRA will help reduce our cost of investing in projects that will support our commitment to reduce emissions and provide customers affordable, reliable, and clean energy over the longer term.

Employee Retirement Savings Plan Matter

In May 2022, a putative class action, Munt, et al. v. WEC Energy Group, Inc., et al., was filed in the United States District Court for the Eastern District of Wisconsin - Milwaukee Division. The plaintiffs allege that WEC Energy Group and others breached their fiduciary duties with respect to the operation and oversight of WEC Energy Group's Employee Retirement Saving Plan (the “Plan”) in violation of the Employee Retirement Income Security Act of 1974, as amended. The class is alleged to be participants in the Plan from May 10, 2016 through the date of judgment. The complaint seeks injunctive relief, damages, interest, costs, and attorneys' fees.
