Non-Controlling Interest in Subsidiaries. Non-controlling interest in subsidiaries on the Consolidated Balance Sheet and net loss attributable to non-controlling interest on the Consolidated Statement of Income represent the portion of equity ownership and earnings, respectively, of subsidiaries that are not attributable to equity holders of ALLETE. These amounts are primarily related to the tax equity financing structures for ALLETE Clean Energy’s 106 MW Glen Ullin, 80 MW South Peak, and 303 MW Diamond Spring and 303 MW Caddo wind energy facilities as well as ALLETE’s equity investment in the 250 MW Nobles 2 wind energy facility.

Subsequent Events. The Company performed an evaluation of subsequent events for potential recognition and disclosure through the date of the financial statements issuance.

On September 22, 2021, South Shore Energy, ALLETE’s non-rate regulated, Wisconsin subsidiary, entered into an agreement with a wholly-owned subsidiary of Basin pursuant to which South Shore Energy agreed to sell to Basin a portion of its interest in NTEC for approximately $20 million representing reimbursement of current costs plus a fee for prior development costs and risks incurred. Pursuant to this transaction, which closed on October 1, 2021, South Shore Energy sold a portion of its undivided ownership interest in NTEC to Basin, such that, South Shore Energy now owns a 20 percent undivided ownership interest in NTEC, Basin owns a 30 percent undivided ownership interest in NTEC and Dairyland Power Cooperative continues to own a 50 percent undivided ownership interest in NTEC. The closing of the transaction resulted in the recognition of an approximately $8.5 million after-tax gain recorded in Corporate and Other in the fourth quarter of 2021, related to prior development costs and risks incurred. NTEC is an approximately 600 MW proposed combined-cycle natural gas-fired generating facility to be built in Superior, Wisconsin. Construction of NTEC is subject to obtaining additional permits from local, state and federal authorities. The total project cost is estimated to be approximately $700 million, of which South Shore Energy’s portion is expected to be approximately $140 million. South Shore Energy’s portion of NTEC project costs incurred through September 30, 2021, is approximately $15 million of which approximately $8 million related to development costs sold to Basin.

NOTE 2. REGULATORY MATTERS

Regulatory matters are summarized in Note 4. Regulatory Matters to the Consolidated Financial Statements in our 20202021 Form 10-K, with additional disclosure provided in the following paragraphs.

Electric Rates. Entities within our Regulated Operations segment file for periodic rate revisions with the MPUC, PSCW or FERC. As authorized by the MPUC, Minnesota Power also recognizes revenue under cost recovery riders for transmission, renewable, and environmental investments and expenditures. Revenue from cost recovery riders was $29.2$19.5 million for the nine months ended September 30, 20212022 ($22.629.2 million for the nine months ended September 30, 2020)2021).

2020 MinnesotaGeneral Rate Case. In November 2019, Minnesota Power filed a retail rate increase request with the MPUC seeking an average increase of approximately 10.6 percent for retail customers. The rate filing sought a return on equity of 10.05 percent and a 53.81 percent equity ratio. On an annualized basis, the requested final rate increase would have generated approximately $66 million in additional revenue. In December 2019 orders, the MPUC accepted the filing as complete and authorized an annual interim rate increase of $36.1 million beginning January 1, 2020.
ALLETE, Inc. Third Quarter 2021 Form 10-Q

NOTE 2. REGULATORY MATTERS (Continued)
Electric Rates (Continued)

In April 2020, Minnesota Power filed a request with the MPUC that proposed a resolution of Minnesota Power’s 2020 general rate case. Key components of our proposal included removing the power marketing margin credit in base rates and reflecting actual power marketing margins in the fuel adjustment clause effective May 1, 2020; refunding to customers interim rates collected through April 2020; increasing customer rates 4.1 percent compared to the 5.8 percent increase reflected in interim rates; and a provision that Minnesota Power would not file another rate case until at least November 1, 2021, unless certain events occur. In a June 2020 order, the MPUC approved Minnesota Power’s petition and proposal to resolve and withdraw the general rate case. Effective May 1, 2020, customer rates were set at an increase of 4.1 percent with the removal of the power marketing margin credit from base rates. Actual power marketing margins will be reflected in the fuel adjustment clause. Reserves for interim rates of $11.7 million were recorded in the second quarter of 2020 and refunded in the third and fourth quarters of 2020.

2022 Minnesota General Rate Case. On November 1, 2021, Minnesota Power filed a retail rate increase request with the MPUC seeking an average increase of approximately 18 percent for retail customers. The rate filing seeks a return on equity of 10.25 percent and a 53.81 percent equity ratio. On an annualized basis, the requested final rate increase would generate approximately $108 million in additional revenue. OnceIn orders dated December 30, 2021, the MPUC accepted the filing is accepted as complete and authorized an annual interim rate increase ofbeginning January 1, 2022, with approximately $87$80 million subject to refund, which would be an average increase of approximately 14 percent for retail customers, is expected to be implemented within 60 days, subjectcollected in cash and approximately $8 million of interim rates for residential customers deferred with a final determination on recovery at the end of the rate case.

On September 1, 2022, the administrative law judge (ALJ) issued a report containing recommendations that if adopted in whole by the MPUC would result in an increase in rates of approximately $76 million on an annualized basis. On September 23, 2022, Minnesota Power filed exceptions totaling approximately $30 million to the ALJ’s report contesting certain recommendations. A final decision by the MPUC adjustmentis expected in early 2023. Management has evaluated the need for a reserve for interim rate refunds and authorization.concluded that a reserve is not necessary as of September 30, 2022. We cannot predict the level of interim or final rates that may be authorized by the MPUC.

2022 Wisconsin General Rate Case. On June 1, 2022, SWL&P refiled its rate increase request with the PSCW seeking an average increase of 3.6 percent for retail customers. The filing seeks an overall return on equity of 10.4 percent and a 55 percent equity ratio. On an annualized basis, the requested final rate increase would generate approximately $4.3 million in additional revenue.

Minnesota Power Land Sales. In August 2020, Minnesota Power filed a petition with the MPUC for approval to sell land that surrounds several reservoirs on its hydroelectric system and is no longer required to maintain its operations. The land has an estimated value of approximately $100 million, and Minnesota Power proposed to credit ratepayers the net proceeds from the sales in a future rate case or through its renewable resources rider to mitigate future rate increases. At a hearing on October 14, 2021, the MPUC decided to allow the land sales to occur and the proceeds refunded to ratepayers subject to certain conditions and required compliance filings.

Environmental ImprovementRenewable Cost Recovery Rider. Minnesota Power has an approved environmental improvementcost recovery rider in place to charge retail customers on a current basis for the costs of certain renewable investments and expenditures, related toincluding a return on the implementation of the Boswell Unit 4 mercury emissions reduction plan completed in 2015. Updatedcapital invested. Current customer billing rates for the environmental improvementrenewable cost recovery rider were approved by the MPUC in a November 20182020 order. On January 19, 2021, Minnesota Power filed a petition seeking MPUC approval to end the environmental improvement rider, which was approved in an order dated April 20, 2021.

Solar Cost Recovery Rider. In June 2020, Minnesota Power filed a petition seeking MPUC approval of a customer billing rate for solar costs related to investments and expenditures for meeting the state of Minnesota’s solar energy standard, which was approved by the MPUC in an order dated April 20, 2021. New customer billing rates for the solar cost recovery rider were implemented on June 1, 2021. On October 21, 2021,February 2, 2022, Minnesota Power submitted its 2022 solarrenewable factor filing. Upon approvalfiling, which included a request to recover a regulatory asset of $3.8 million related to the recognition of production tax credits due to a metering error at Bison. If the filing is approved, Minnesota Power willwould be authorized to include updated billing rates on customer bills.

Electric Vehicle Charging Infrastructure Petition. On April 8, 2021, Minnesota Power filed a petition seeking approvalbills; any portion disallowed would be charged to install and own DC fast charger stations for electric vehicles across its service territory, implement accompanying rates for those stations, and track and recover investments and expenses for the project. In an order dated October 22, 2021, the MPUC approved Minnesota Power’s petition.earnings.

COVID-19 Related Deferred Accounting. In an order dated March 24, 2020, the PSCW authorized public utilities, including SWL&P, to defer expenditures incurred by the utility resulting from its compliance with state government or regulator orders during Wisconsin’s declared public health emergency for COVID-19. On April 20, 2020, Minnesota Power along with other regulated electric and natural gas service providers in Minnesota filed a joint petition to request MPUC authorization to track incremental costs and expenses incurred as a result of the COVID-19 pandemic, and to defer and record such costs as a regulatory asset, subject to recovery in a future proceeding. In an order dated May 22, 2020, the MPUC approved the joint petition requiring the joint petitioners to track cost and revenue impacts resulting from the COVID-19 pandemic with review for recovery in a future rate proceeding. As of September 30, 2021, Minnesota Power has not deferred any costs or lost revenue, and SWL&P has deferred an immaterial amount of costs.

Minnesota Power submitted a petition in November 2020 to the MPUC requesting authority to track and record as a regulatory asset lost large industrial customer revenue resulting from the idling of USS Corporation’s Keetac plant and Verso Corporation’s paper mill in Duluth, Minnesota. Keetac and Verso Corporation represent revenue of approximately $30 million annually, net of associated expense savings such as fuel costs. Minnesota Power proposed in this petition to defer any lost revenue related to the idling of the Keetac facility and the Verso Corporation paper mill to its next general rate case or other proceeding for review for recovery by the MPUC. In an order dated May 13, 2021, the MPUC denied Minnesota Power’s request.

Fuel Adjustment Clause. In March 2020, Minnesota Power filed its fuel adjustment clause report coveringforecast for 2021, which was approved by the period July 2018MPUC in a December 2020 order, subject to the annual prudence review and true-up filing in 2022. During 2021, Minnesota Power incurred higher fuel and purchased power costs than those forecasted in its May 2020 filing, which resulted in the recognition of an approximately $56 million regulatory asset through December 2019. In a September 2020 order, the MPUC referred the review of Minnesota Power’s forced outage costs during the period of the report, which totaled approximately $8 million, to an administrative law judge (ALJ) for a contested case hearing to recommend to the MPUC if any of those costs should be returned to customers. On August 11, 2021, the ALJ recommended that Minnesota Power refund approximately $5 million to ratepayers; the ALJ’s recommendation is not binding on the MPUC.31, 2021. Minnesota Power submitted exceptionsits annual true-up filing and a significant events filing in March 2022 requesting recovery of these under-collected fuel adjustment clause recoveries. No parties objected to the ALJ’s reportrequest; recovery of the regulatory asset began in April 2022 and will continue through mid-2023. The MPUC approved recovery of the regulatory asset in an order dated July 5, 2022.

Minnesota Power has also incurred higher fuel and purchased power costs in 2022 than those factored in its fuel adjustment forecast filed in May 2021 for 2022, which resulted in the recognition of an approximately $23 million regulatory asset as of September 30, 2022. Minnesota Power filed a significant events filing in June 2022 requesting recovery of the under-collected fuel adjustment clause recoveries that are expected for 2022 from August 2022 through December 2022. No parties objected to the MPUC stating that it disagreed withrequest and higher rates were implemented in August 2022 to recover the ALJ’s recommendation and that no refund should be made as the Company operated its facilities in accordance with good utility practice. A decision fromexpected under-collection of fuel adjustment clause recoveries, subject to final approval by the MPUC which is expected in the fourth quarter of 2021.2023.

Conservation Improvement Program. On April 1, 2021,2022, Minnesota Power submitted its 20202021 consolidated filing detailing Minnesota Power’s CIP program results and requesting a CIP financial incentive of $2.4$1.9 million based upon MPUC procedures, which was recognized in the thirdsecond quarter of 20212022 upon approval by the MPUC in an order dated September 7, 2021.at a hearing on June 30, 2022. In 2020,2021, a CIP financial incentive of $2.4 million was recognized in the third quarter upon approval by the MPUC of Minnesota Power’s 20192020 CIP consolidated filing. CIP financial incentives are recognized in the period in which the MPUC approves the filing.

NOTE 2. REGULATORY MATTERS (Continued)

2021 Integrated Resource Plan. On February 1, 2021, Minnesota Power filed its latest IRP with the MPUC, which outlines its clean-energy transition plans through 2035. These plans include expanding its renewable energy supply, achieving coal-free operations at its facilities by 2035, and investing in a resilient and flexible transmission and distribution grid. As part of these plans, Minnesota Power anticipates adding approximately 400 MW of new wind and solar energy resources, retiring Boswell Unit 3 by 2030 and transforming Boswell Unit 4 to be coal-free by 2035. Minnesota Power’s plans recognize that advances in technology will play a significant role in completing its transition to carbon-free energy supply, reliably and affordably. A final decision on the IRP is expected in mid-2022.

Nemadji Trail Energy Center. In 2017, Minnesota Power submitted a resource package to the MPUC which included requesting approvalfourth quarter of a natural gas capacity dedication and other affiliated-interest agreements for NTEC, an approximately 600 MW proposed combined-cycle natural gas-fired generating facility to be built in Superior, Wisconsin, which will be jointly owned by Dairyland Power Cooperative, Basin and South Shore Energy, ALLETE’s non-rate regulated, Wisconsin subsidiary. Minnesota Power is expected to purchase approximately 20 percent of the facility's output starting in 2025 pursuant to the capacity dedication agreement. (See Note 1. Operations and Significant Accounting Policies – Subsequent Events.) In a January 2019 order, the MPUC approved Minnesota Power’s request for approval of the NTEC natural gas capacity dedication and other affiliated-interest agreements. In 2019, the Minnesota Court of Appeals reversed and remanded the MPUC’s decision to approve certain affiliated-interest agreements. On April 21, 2021, the Minnesota Supreme Court reversed the Minnesota Court of Appeal’s decision by ruling that the MPUC is not required to conduct a review under the Minnesota Environmental Policy Act before approving affiliated-interest agreements that govern construction and operation of a Wisconsin power plant by a Minnesota utility, and remanded the case back to the Minnesota Court of Appeals for review of remaining issues on appeal. On August 23, 2021, the Minnesota Court of Appeals affirmed the decision by the MPUC to approve certain affiliated-interest agreements.

NOTE 2. REGULATORY MATTERS (Continued)

Verso Corporation Electric Service Agreement. On August 2, 2021, Minnesota Power filed a petition with the MPUC requesting the MPUC to interpret the electric service agreement (ESA) between Minnesota Power and Verso Corporation finding that Verso Corporation has tariff obligations and owes minimum firm demand payments during the term of the ESA. Minnesota Power filed this petition in response to Verso Corporation ceasing to make its minimum firm demand payments under the ESA. At a hearing on October 14, 2021, the MPUC agreed with Minnesota Power’s petition and concluded that the MPUC has jurisdiction to interpret the relevant provisions of the ESA, and the ESA requires Verso Corporation to continue full minimum firm demand payments for a period of two years from the January 29, 2021, notice of termination, regardless of Minnesota Power’s electricity sales to a new customer at the former Verso Corporation facility. Minnesota Power has a receivable related to the ESA of approximately $1.2 million as of September 30, 2021. In addition, Verso Corporation owes Minnesota Power payments under a steam agreement, which is proceeding through arbitration. Minnesota Power has a receivable under the steam agreement of approximately $2.4 million as of September 30, 2021. Minnesota Power expects to fully collect these outstanding account receivable balances as well as Verso Corporation’s remaining obligations under the ESA.2022.

Regulatory Assets and Liabilities. Our regulated utility operations are subject to accounting guidance for the effect of certain types of regulation. Regulatory assets represent incurred costs that have been deferred as they are probable for recovery in customer rates. Regulatory liabilities represent obligations to make refunds to customers and amounts collected in rates for which the related costs have not yet been incurred. The Company assesses quarterly whether regulatory assets and liabilities meet the criteria for probability of future recovery or deferral. With the exception of the regulatory asset for Boswell Units 1 and 2 net plant and equipment, no other regulatory assets are currently earning a return. The recovery, refund or credit to rates for these regulatory assets and liabilities will occur over the periods either specified by the applicable regulatory authority or over the corresponding period related to the asset or liability.

NOTE 3. ACQUISITIONS

2022 Activity

New Energy. On April 15, 2022, a wholly-owned subsidiary of ALLETE acquired 100 percent of the membership interests of New Energy for a purchase price of $165.5 million. Total consideration of approximately $158.8 million was paid in cash on the acquisition date, which is net of cash acquired and debt assumed. New Energy, which is headquartered in Annapolis, Maryland, is a renewable energy development company with a primary focus on solar and storage facilities while also offering comprehensive operations, maintenance and asset management services. The acquisition of New Energy is consistent with ALLETE’s stated strategy of additional investment in renewable energy and related infrastructure across North America to support the Company’s sustainability-in-action strategy while providing potential long-term earnings growth.

The acquisition was accounted for as a business combination and the purchase price was allocated based on the preliminary estimated fair values of the assets acquired and the liabilities assumed at the date of acquisition, as shown in the following table. The allocation of the purchase price is subject to judgment and the preliminary estimated fair value of the assets acquired and the liabilities assumed may be adjusted when the valuation analysis is complete in subsequent periods. Preliminary estimates subject to adjustment in subsequent periods relate primarily to working capital; subsequent adjustments could impact the amount of goodwill recorded. Fair value measurements were valued primarily using the discounted cash flow method and replacement cost basis. The goodwill recorded is primarily attributable to the highly skilled workforce of New Energy and synergies expected to arise as a result of the acquisition.

Since the acquisition in April 2022, aggregate revenue was $39.9 million. The Company has not presented separate results of operations since closing or combined pro forma financial information of the Company and New Energy since the beginning of 2021, as the results of operations for New Energy are not material to the Company's consolidated financials.

During the third quarter of 2022, the Company recorded purchase accounting adjustments related to the acquisition of New Energy which resulted in an increase to net liabilities of $6.2 million, current assets increased by $1.4 million and goodwill increased by $4.8 million.

Acquisition-related costs were $2.6 million after-tax, expensed as incurred during 2022 and recorded in Operating and Maintenance on the Consolidated Statement of Income.

NOTE 3.4. EQUITY INVESTMENTS

Investment in ATC. Our wholly-owned subsidiary, ALLETE Transmission Holdings, owns approximately 8 percent of ATC, a Wisconsin-based utility that owns and maintains electric transmission assets in portions of Wisconsin, Michigan, Minnesota and Illinois. We account for our investment in ATC under the equity method of accounting.

ATC’s authorized return on equity iswas 10.02 percent, or 10.52 percent including an incentive adder for participation in a regional transmission organization, based on a May 2020 FERC order that granted rehearing of a 2019 FERC order. These FERC orders arewhich was subject to various outstanding legal challenges related to the return on equity calculation and refund period ordered by the FERC. If these legal challenges are successful,On August 9, 2022, the U.S. Court of Appeals for the District of Columbia Circuit vacated and remanded the 2020 FERC order back to FERC. As a result of this decision, ATC may be required to providerecorded a reserve in the third quarter of 2022 for anticipated refunds to its customers of up tofor approximately $66$31 million of which our share was $2.4 million pre-tax. We cannot predict the return on equity FERC will ultimately authorize in the remanded proceeding.

In addition, the FERC issued a Notice of Proposed Rulemaking in April 2021 proposing to limit the 50 basis point incentive adder for participation in a regional transmission organization to only the first three years of membership in such an organization. If this proposal is adopted, our equity in earnings from ATC would be reduced by approximately $5$1 million pre-tax.pre-tax annually.

Investment in Nobles 2. Our subsidiary, ALLETE South Wind, owns 49 percent of Nobles 2, the entity that owns and operates thea 250 MW wind energy facility in southwestern Minnesota pursuant to a 20-year PPA with Minnesota Power. We account for our investment in Nobles 2 under the equity method of accounting.

NOTE 4.5. FAIR VALUE

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). We utilize market data or assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. These inputs can be readily observable, market corroborated or generally unobservable. We primarily apply the market approach for recurring fair value measurements and endeavor to utilize the best available information. Accordingly, we utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. These inputs, which are used to measure fair value, are prioritized through the fair value hierarchy. 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). Descriptions of the three levels of the fair value hierarchy are discussed in Note 6. Fair Value to the Consolidated Financial Statements in our 20202021 Form 10-K.


ALLETE, Inc. Third Quarter 2022 Form 10-Q

NOTE 5. FAIR VALUE (Continued)

The following tables set forth, by level within the fair value hierarchy, our assets and liabilities that were accounted for at fair value on a recurring basis as of September 30, 2021,2022, and December 31, 2020.2021. Each asset and liability is classified based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement requires judgment, which may affect the valuation of these assets and liabilities and their placement within the fair value hierarchy levels. The estimated fair value of Cash and Cash Equivalents listed on the Consolidated Balance Sheet approximates the carrying amount and therefore is excluded from the recurring fair value measures in the following tables.

OnFebruary 28, 2022, ALLETE entered into an unsecured term loan agreement (February Term Loan) to borrow up to $175 million. No draws were made on the February Term Loan, which was subsequently terminated in April 2022.

On March 25, 2021,24, 2022, ALLETE entered into a $150$170 million unsecured term loan agreement (Term(March Term Loan). An additional draw of $35 million through the exercise of an accordion feature was made during the second quarter of 2021. As of September 30, 2021, we have borrowed the full amount of $185 million. The Term Loan is due March 24, 2022,23, 2023, and may be repaid at any time. Interest is payable monthly at a rate per annum equal to LIBORSOFR plus 0.75 percent. Proceeds from the Term Loan were used for general corporate purposes.

On September 1, 2021,August 9, 2022, ALLETE issued $100$75 million of its First Mortgage Bonds (Bonds) to certain institutional buyers in the private placement market. The Bonds, which bear interest at 2.794.54 percent, will mature in September 2031August 2032 and pay interest semi-annually in MarchFebruary and SeptemberAugust of each year, commencing on March 1, 2022.February 9, 2023. ALLETE has the option to prepay all or a portion of the Bonds at its discretion, subject to a make-whole provision. The Bonds are subject to additional terms and conditions which are customary for these types of transactions. Proceeds from the sale of the Bonds were used to fund utility capital investment and for general corporate purposes. The Bonds were sold in reliance on an exemption from registration under Section 4(a)(2) of the Securities Act of 1933, as amended, to institutional accredited investors.

Financial Covenants. Our long-term debt arrangements contain customary covenants. In addition, our lines of credit and letters of credit supporting certain long-term debt arrangements contain financial covenants. Our compliance with financial covenants is not dependent on debt ratings. The most restrictive financial covenant requires ALLETE to maintain a ratio of indebtedness to total capitalization (as the amounts are calculated in accordance with the respective long-term debt arrangements) of less than or equal to 0.65 to 1.00, measured quarterly. As of September 30, 2021,2022, our ratio was approximately 0.430.39 to 1.00. Failure to meet this covenant would give rise to an event of default if not cured after notice from the lender, in which event ALLETE may need to pursue alternative sources of funding. Some of ALLETE’s debt arrangements contain “cross-default” provisions that would result in an event of default if there is a failure under other financing arrangements to meet payment terms or to observe other covenants that would result in an acceleration of payments due. ALLETE has no significant restrictions on its ability to pay dividends from retained earnings or net income. As of September 30, 2021,2022, ALLETE was in compliance with its financial covenants.

NOTE 6.7. COMMITMENTS, GUARANTEES AND CONTINGENCIES

Power Purchase and Sale Agreements. Our long-term PPAs have been evaluated under the accounting guidance for variable interest entities. We have determined that either we have no variable interest in the PPAs or, where we do have variable interests, we are not the primary beneficiary; therefore, consolidation is not required. These conclusions are based on the fact that we do not have both control over activities that are most significant to the entity and an obligation to absorb losses or receive benefits from the entity’s performance. Our financial exposure relating to these PPAs is limited to our capacity and energy payments.

Our PPAs are summarized in Note 8. Commitments, Guarantees and Contingencies to the Consolidated Financial Statements in our 20202021 Form 10-K, with additional disclosure provided in the following paragraphs.

Square Butte PPA. As of September 30, 2021,2022, Square Butte had total debt outstanding of $256.9$192.7 million. Fuel expenses are recoverable through Minnesota Power’s fuel adjustment clause and include the cost of coal purchased from BNI Energy under a long-term contract. Minnesota Power’s cost of power purchased from Square Butte during the nine months ended September 30, 2021,2022, was $60.3$63.8 million ($59.960.3 million for the same period in 2020)2021). This reflects Minnesota Power’s pro rata share of total Square Butte costs based on the 50 percent output entitlement. Included in this amount was Minnesota Power’s pro rata share of interest expense of $4.3$3.7 million ($5.44.3 million for the same period in 2020)2021). Minnesota Power’s payments to Square Butte are approved as a purchased power expense for ratemaking purposes by both the MPUC and the FERC.

Minnkota Power PSA. Minnesota Power has a PSA with Minnkota Power, which commenced in 2014. Under the PSA, Minnesota Power is selling a portion of its entitlement from Square Butte to Minnkota Power, resulting in Minnkota Power’s net entitlement increasing and Minnesota Power’s net entitlement decreasing until Minnesota Power’s share is eliminated at the end of 2025. Of Minnesota Power’s 50 percent output entitlement, Minnesota Power sold to Minnkota Power approximately 32 percent in 2022 and 28 percent in 2021 and in 2020.2021.

Coal, Rail and Shipping Contracts. Minnesota Power has coal supply agreements providing for the purchase of a significant portion of its coal requirements through December 2021.2025. Minnesota Power also has coal transportation agreements in place for the delivery of a significant portion of its coal requirements through December 2021.2024. The costs of fuel and related transportation costs for Minnesota Power’s generation are recoverable from Minnesota Power’s retail and municipal utility customers through the fuel adjustment clause.

Environmental Matters.

Our businesses are subject to regulation of environmental matters by various federal, state and local authorities. A number of regulatory changes to the Clean Air Act, the Clean Water Act and various waste management requirements have been promulgated by both the EPA and state authorities over the past several years. Minnesota Power’s facilities are subject to additional requirements under many of these regulations. Minnesota Power is reshaping its generation portfolio, over time, to reduce its reliance on coal, has installed cost-effective emission control technology, and advocates for sound science and policy during rulemaking implementation.

We consider our businesses to be in substantial compliance with currently applicable environmental regulations and believe all necessary permits have been obtained. We anticipate that with many state and federal environmental regulations and requirements finalized, or to be finalized in the near future, potential expenditures for future environmental matters may be material and require significant capital investments. Minnesota Power has evaluated various environmental compliance scenarios using possible outcomes of environmental regulations to project power supply trends and impacts on customers.

We review environmental matters on a quarterly basis. Accruals for environmental matters are recorded when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated based on current law and existing technologies. Accruals are adjusted as assessment and remediation efforts progress, or as additional technical or legal information becomes available. Accruals for environmental liabilities are included in the Consolidated Balance Sheet at undiscounted amounts and exclude claims for recoveries from insurance or other third parties. Costs related to environmental contamination treatment and cleanup are expensed unless recoverable in rates from customers.

Air. The electric utility industry is regulated both at the federal and state level to address air emissions. Minnesota Power’s thermal generating facilities mainly burn low-sulfur western sub-bituminous coal. All of Minnesota Power’s coal-fired generating facilities are equipped with pollution control equipment such as scrubbers, baghouses and low NOX technologies. Under currently applicable environmental regulations, these facilities are substantially compliant with emission requirements.

Cross-State Air Pollution Rule (CSAPR). The CSAPR requires certain states in the eastern half of the U.S., including Minnesota, to reduce power plant emissions that contribute to ozone or fine particulate pollution in other states. The CSAPR does not require installation of controls but does require facilities have sufficient allowances to cover their emissions on an annual basis. These allowances are allocated to facilities from each state’s annual budget, and can be bought and sold. Based on our review of the NOX and SO2 allowances issued and pending issuance, we currently expect generation levels and emission rates will result in continued compliance with the CSAPR. The EPA’s CSAPR Update Rule issued onin March 15, 2021 to reviserevising the 2016 CSAPR Update does not apply to the state of Minnesota and is therefore not currently projected to affect Minnesota Power’s CSAPR compliance. The State of Minnesota has not been identified in litigation as a culpable upwind emission source to downwind states, and previous EPA air quality modeling has demonstrated that Minnesota is not a significant contributor to downwind air quality attainment challenges. Minnesota Power will continue to monitor ongoing CSAPR rulemakings and compliance implementation.implementation, including the EPA’s Good Neighbor Rule proposed on April 6, 2022, to modify certain aspects of the CSAPR’s program scope and extent.

National Ambient Air Quality Standards (NAAQS). The EPA is required to review the NAAQS every five years. If the EPA determines that a state’s air quality is not in compliance with the NAAQS, the state is required to adopt plans describing how it will reduce emissions to attain the NAAQS. Minnesota Power actively monitors NAAQS developments and compliance costs for existing standards or proposed NAAQS revisions are not currently expected to be material. The EPA is currently reviewing the secondary NAAQS for NOx and SO2, as well as particulate matter. OnIn June 10, 2021, the EPA announced it will reconsider the December 2020 final rule retaining the 2012 particulate matter NAAQS,NAAQS. A proposed rulemaking was anticipated in August 2022, with a proposed rulemaking anticipatedfinal rule in mid-2022.March 2023, but none has been issued at this time. The EPA has not stated its intent with regard toalso announced in October 2021 that it was reconsidering the 2020 Ozone NAAQS rule finalized in December 2020.2020, and issued a policy assessment on April 28, 2022, recommending retention of the current standard. A proposed Ozone NAAQS rule is expected in the first half of 2023.

EPA Good Neighbor Plan for 2015 Ozone NAAQS. On April 6, 2022, the EPA published a proposed rule, the Good Neighbor Plan, to address regional ozone transport for the 2015 Ozone NAAQS by reducing NOx emissions during the period of May 1 through September 30 (ozone season). This rule is intended to address certain good neighbor or interstate transport provisions of the Clean Air Act relative to the 2015 Ozone NAAQS. In the justification for the proposed rule, the EPA asserted that 26 states, including Minnesota, are modeled as significant contributors to downwind states’ challenges in attaining or maintaining ozone NAAQS compliance within their state borders. The Good Neighbor Plan proposes to resolve this interstate transport issue by implementing a variety of NOx reduction strategies, including federal implementation plan requirements, NOx emission limitations, and ozone season allowance program requirements, beginning with the 2023 ozone season. The proposed rule would apply to fossil-fuel fired power plants in 25 states and certain other industrial sources in 23 states. Implementation of the rule would occur in part through changes to the existing CSAPR program.

Minnesota Power reviewed the proposed rule, assessed its potential impacts and submitted public comments to the EPA on June 21, 2022. Concerns noted by Minnesota Power and other entities included the technical accuracy of the EPA’s assumptions and methods used to identify Minnesota as a significant contributor state, as well as the proposed rule’s intended timeline. Anticipated compliance costs related to the Good Neighbor Plan cannot yet be estimated; however, the costs could be material, including costs of additional NOx controls, emission allowance program participation, or operational changes, if any are required. Minnesota Power would seek recovery of additional costs through a rate proceeding. The EPA intends to issue a final rule in early 2023.

EPA National Emission Standards for Hazardous Air Pollutants for Major Sources: Industrial, Commercial and Institutional Boilers and Process Heaters (Industrial Boiler MACT) Rule. A final rule issued by the EPA for Industrial Boiler MACT became effective in 2012 with compliance required at major existing sources in 2016. Minnesota Power’s Hibbard Renewable Energy Center and Rapids Energy Center are subject to this rule. Compliance with the Industrial Boiler MACT Rule consisted largely of adjustments to fuels and operating practices and compliance costs were not material. Subsequent to this initial rulemaking, litigation from 2016 through 2018 resulted in court orders directing that the EPA reconsider certain aspects of the regulation including the basis for and numerical value of several different emission limits. On October 6, 2022, the EPA published a final rule in the Federal Register incorporating these changes. The rule will become effective on December 5, 2022 and impose a 3-year compliance deadline of December 5, 2025. Minnesota Power is actively reviewing this new regulation to assess if any changes are needed to achieve compliance. Compliance costs associated with the new Industrial Boiler MACT Rule cannot yet be estimated; however, the costs could be material. Minnesota Power would seek recovery of additional costs through a rate proceeding.

Climate Change. The scientific community generally accepts that emissions of GHG are linked to global climate change which creates physical and financial risks. Physical risks could include, but are not limited to: increased or decreased precipitation and water levels in lakes and rivers; increased or other changes in temperatures; and changes in the intensity and frequency of extreme weather events. These all have the potential to affect the Company’s business and operations. We are addressing climate change by taking the following steps that also ensure reliable and environmentally compliant generation resources to meet our customers’ requirements:

Expanding renewable power supply for both our operations and the operations of others;
Providing energy conservation initiatives for our customers and engaging in other demand side management efforts;
Improving efficiency of our generating facilities;
Supporting research of technologies to reduce carbon emissions from generating facilities and carbon sequestration efforts;
Evaluating and developing less carbon intensive future generating assets such as efficient and flexible natural gas-fired generating facilities;
Managing vegetation on right-of-way corridors to reduce potential wildfire or storm damage risks; and
Practicing sound forestry management in our service territories to create landscapes more resilient to disruption from climate-related changes, including planting and managing long-lived conifer species.

EPA Regulation of GHG Emissions. In 2019, the EPA finalized several separate rulemakings regarding regulating carbon emissions from electric utility generating units. These rulemakings included repealing the Clean Power Plan (CPP) and adopting the Affordable Clean Energy Rule under Section 111(d) of the Clean Air Act (CAA) to regulate CO2 emissions at existing coal-fired power plants. The CPP was first announced as a proposed rule under Section 111(d) of the CAA for existing power plants entitled “Carbon Pollution Emission Guidelines for Existing Stationary Sources: Electric Generating Units”. The Affordable Clean Energy Rule established emissions guidelines for states to use when developing plans to limit CO2 coal-fired power plants. The EPA also published regulations for the state implementation of the Affordable Clean Energy Rule and other Section 111(d) rules. Affected facilities for Minnesota Power included Boswell Units 3 and 4, and Taconite Harbor Units 1 and 2, which are currently economically idled.

On January 19, 2021, the D.C. Circuit issued an opinion vacating the Affordable Clean Energy Rule and remanded the Affordable Clean Energy Rule back to the EPA for further consideration, consistent with the D.C. Circuit’s finding that the EPA erred in interpreting the CAA, pending rehearing or appeal. Four petitions for review of the D.C. Circuit’s opinion were subsequently granted by the U.S. Supreme Court on October 29, 2021, consolidated under West Virginia v. EPA et al. On June 30, 2022, the U.S. Supreme Court released its opinion in favor of West Virginia and aligned parties. The Supreme Court found the EPA’s CPP structure of generation shifting to be disallowed under Section 111(d) of the CCA on grounds of the major questions doctrine. The court did not opine upon the regulatory approach the EPA proposed in the Affordable Clean Energy Rule. The petitions were remanded to the D.C. Circuit. The EPA has indicated that it is working onintends to issue a proposed rule in early 2023 with a new set of emission guidelines for states to follow in submitting state plans to establish a Best Systemand implement standards of Emissions Reductionperformance for GHG emissions from existing fossil fuel-fired electric generating units to direct states in regulating GHGs within their borders; however, no timeline has been disclosed.units. Minnesota Power will continue to monitor any related guidelines and rulemakings issued by the EPA or state regulatory authorities.

On April 22, 2021, the Biden Administration announced a goal to reach 100 percent carbon pollution-free electricity by 2035 as part of the Nationally Determined Contributions pledge, which is part of an international effort to limit global warming. At this time, no specific regulatory pathway to achieve these reductions has been proposed. Minnesota Power will continue to monitor these developments.

Minnesota had already initiated several measures consistent with those called for under the now repealed CPP and vacated Affordable Clean Energy Rule. Minnesota Power continues implementing its EnergyForward strategic plan that provides for significant emission reductions and diversifying its electricity generation mix to include more renewable and natural gas energy. We are unable to predict the GHG emission compliance costs we might incur as a result of a replacement for the Affordable Clean Energy Rule or other future laws, regulations or administrative policies; however, the costs could be material. Minnesota Power would seek recovery of additional costs through a rate proceeding.

Additionally on January 13, 2021, the EPA issued a rulemaking to apply CO2 emission New Source Performance Standards (NSPS) to new, modified and reconstructed fossil fuel-fired electric generating units under Section 111(b) of the CAA. Currently, the EPA is a performing a comprehensive review of the Section 111(b) GHG NSPS for electric generating units, with a notice of proposed rulemaking expected in early 2023. Minnesota Power is monitoring the NSPS final rule and any further Section 111(b) developments including their potential impact to the Company. The Company’s proposed combined-cycle natural gas-fired generating facility, NTEC, is expected to meet these NSPS requirements.

Water. The Clean Water Act requires NPDES permits be obtained from the EPA (or, when delegated, from individual state pollution control agencies) for any wastewater discharged into navigable waters. We have obtained all necessary NPDES permits, including NPDES storm water permits for applicable facilities, to conduct our operations.

Steam Electric Power Generating Effluent Limitations Guidelines. In 2015, the EPA issued revised federal effluent limitation guidelines (ELG) for steam electric power generating stations under the Clean Water Act. It set effluent limits and prescribed BACT for several wastewater streams, including flue gas desulphurization (FGD) water, bottom ash transport water and coal combustion landfill leachate. In 2017, the EPA announced a two-year postponement of the ELG compliance date of November 1, 2018, to November 1, 2020, while the agency reconsidered the bottom ash transport water (BATW) and FGD wastewater provisions. On April 12, 2019, the U.S. Court of Appeals for the Fifth Circuit vacated and remanded back to the EPA portions of the ELG that allowed for continued discharge of legacy wastewater and leachate. On October 13, 2020, the EPA published a final ELG Rule allowing re-use of bottom ash transport water in FGD scrubber systems with limited discharges related to maintaining system water balance. The rule sets technology standards and numerical pollutant limits for discharges of bottom ash transport water and FGD wastewater. Compliance deadlines depend on subcategory, with compliance generally required as soon as possible, beginning after October 13, 2021, but no later than December 31, 2025, or December 31, 2028, in some specific cases. The rule also established new subcategories for retiring high-flow and low-utilization units, and established a voluntary incentives program for FGD wastewater. In accordance with the January 2021 Executive Order 13990, the EPA was mandated to conduct a review of actions and polices taken during the prior administration, including the 2020 ELG Rule. On September 14, 2021, the EPA published a notice of availability for preliminary effluent guidelines program plan. In the plan, the EPA confirmed the agency is initiating a rulemaking process to strengthen wastewater pollution limitations from FGD and bottom ash transport water discharges while the 2020 ELG Rule remains in effect. The EPA is expected to publish a proposed rule in the fall ofNovember 2022.

The ELG's potential impact on Minnesota Power operations is primarily at Boswell. Boswell currently discharges bottom ash contact water through its NPDES permit, and also has a closed-loop FGD system that does not discharge to surface waters, but may do so in the future. With Boswell’s planned conversion to dry FGD handling and storage, ongoing FGD water generation will be reduced, and the majority of FGD waters will be legacy waters to be dewatered from existing impoundments. Re-use and onsite consumption for the majority of FGD waters is planned at Boswell.

Under the new2020 ELG rule, most bottom ash transport water discharge to surface waters must cease no later than December 31, 2025, except for small discharges needed to retain water balance. The majority of bottom ash transport water will either need to be re-used in a closed-loop process or routed to a FGD scrubber. AtFGD wastewater is required to meet stringent water quality standards for discharge to surface water.

Bottom ash transport and FGD wastewater ELG’s are not currently expected to have a significant impact on Minnesota Power operations. Boswell theEnergy Center, where ELG’s are primarily applicable, completed conversion to dry bottom ash handling systems are planned to be converted toand installed a FGD dewatering system in September 2022. The dry process, which will eliminate the discharge ofconversion projects eliminated bottom ash transport water.water and minimized wastewater from the FGD system. Re-use and onsite consumption is planned for the remaining FGD waste stream and for dewatering legacy wastewater from Boswell’s existing impoundments. Water re-use and consumption activities are expected to eliminate the need for surface water discharges prior to the current ELG Rule deadline of December 31, 2025.

The EPA’s additional reconsideration of legacy wastewater and leachate discharge requirements has the potential to reduce timelines for dewatering Boswell’s existing ponds. The timingimpact leachate discharges associated with the closed impoundment at the Laskin and Taconite Harbor Energy Center Dry Ash Landfill. In its spring 2022 Unified Agenda, the EPA announced it intends to consolidate consideration of a draft rule addressing legacy wastewater and leachate with the ELG/FGD and BATW proposed rulemaking expected in November 2022. It is currently unknown.

Permitted Water Discharges – Sulfate. In 2017, the MPCA released a draft water quality standard in an attempt to update Minnesota’s existing 10 mg/L sulfate limit for waters used for the production of wild rice with the proposed rulemaking heard before an administrative law judge (ALJ). In 2018, the ALJ rejected significant portions of the proposed rulemaking and the MPCA subsequently withdrew the rulemaking. The existing 10 mg/L limit remains in place, but the MPCA is currently prohibited under state law from listing wild rice waters as impaired or requiring sulfate reduction technology.

In April 2021, the MPCA’s proposed list of impaired waters submitted pursuant to the Clean Water Act was partially rejected by the EPA due to the absence of wild rice waters listed for sulfate impairment. The EPA subsequently proposedtransmitted a final list of 3032 EPA-added wild rice waters in a separate listing processto the MPCA on April 29, 2021, followed by aNovember 5, 2021. This list of three additional wild rice waters proposed separately on September 1, 2021. A final impaired waters listing is expected to follow, which could subsequently be used to set sulfate limits in discharge permits for power generation facilities and municipal and industrial customers, including paper and pulp facilities, and mining operations. At this time we are unable to determine the specific impacts these developments may have on Minnesota Power operations, if any. Minnesota Power would seek recovery of additional costs through a rate proceeding.

Solid and Hazardous Waste. The Resource Conservation and Recovery Act of 1976 regulates the management and disposal of solid and hazardous wastes. We are required to notify the EPA of hazardous waste activity and, consequently, routinely submit reports to the EPA.

Coal Ash Management Facilities. Minnesota Power produces the majority of its coal ash at Boswell, with small amounts of ash generated at Hibbard Renewable Energy Center. Ash storage and disposal methods include storing ash in clay-lined onsite impoundments (ash ponds), disposing of dry ash in a lined dry ash landfill, applying ash to land as an approved beneficial use, and trucking ash to state permitted landfills.

Coal Combustion Residuals from Electric Utilities (CCR). In 2015, the EPA published the final rule regulating CCR as nonhazardous waste under Subtitle D of the Resource Conservation and Recovery Act (RCRA) in the Federal Register. The rule includes additional requirements for new landfill and impoundment construction as well as closure activities related to certain existing impoundments. Costs of compliance for Boswell and Laskin are expected to be incurred primarily over the next 15 years and be between approximately $65 million and $120 million. Compliance costs for CCR at Taconite Harbor are not expected to be material. Minnesota Power would seek recovery of additional costs through a rate proceeding.

Minnesota Power continues to work on minimizing costs through evaluation of beneficial re-use and recycling of CCR and CCR-related waters. In 2017, the EPA announced its intention to formally reconsider the CCR rule under Subtitle D of the RCRA. In March 2018, the EPA published the first phase of the proposed rule revisions in the Federal Register. In 2018, the EPA finalized revisions to elements of the CCR rule, including extending certain deadlines by two years, the establishment of alternative groundwater protection standards for certain constituents and the potential for risk-based management options at facilities based on site characteristics. In 2018, a U.S. District Court for the District of Columbia decision vacated specific provisions of the CCR rule. The court decision resulted in a change to the status of three existing clay-lined impoundments at Boswell that must now be considered unlined. The EPA proposed additional rule revisions in 2019 to address outstanding issues from litigation and closure timelines for unlined impoundments, respectively. The first of these rules, CCR Part A Rule, was finalized in September 2020. The Part A Rule revision requires unlined impoundments to cease disposal of waste as soon as technically feasible but no later than April 11, 2021. This deadline has tolled forward as the EPA did not make any variance application determinations by that date. Minnesota Power sought EPA approval under the Part A Rule to extend the closure date for the two active Boswell impoundments in November 2020 through a2020. Upon completion of dry ash conversion activities, Boswell ceased disposal in both impoundments on September 17, 2022 and formally withdrew the CCR Part A Application. The EPA acknowledged the Part A variance application withdrawal on September 20, 2022, and continuesindicated it has updated the webpage to operate theshow Boswell has ceased waste disposal in impoundments. The EPA also indicated that no further EPA review of Boswell’s Part A variance application will occur. Both impoundments pending a final determination by the EPA. are now inactive and have initiated closure.

Additionally, the EPA released a proposed Part B rulemaking in February 2020 that addressedaddressing options for beneficial reuse of CCR materials, alternative liner demonstrations, and other CCR regulatory revisions. Portions of the Part B Rule addressing alternative liner equivalency standards were finalized in November 2020. According to the EPA’s spring 2022 regulatory agenda, finalization of the remainder of the proposed Part B Rule wasis expected in mid-2021, but has not yet been published.early 2023. Expected compliance costs at Boswell due to the court decision and subsequent rule revisions are reflected in our estimate of compliance costs for the CCR rule noted previously. Minnesota Power would seek recovery of additional costs through a rate proceeding.

Uncertain Tax Positions. As of September 30, 2021,2022, we had gross unrecognized tax benefits of $1.5$1.3 million ($1.41.3 million as of December 31, 2020)2021). Of the total gross unrecognized tax benefits, $0.6 million represents the amount of unrecognized tax benefits included on the Consolidated Balance Sheet that, if recognized, would favorably impact the effective income tax rate. The unrecognized tax benefit amounts have been presented as reductions to the tax benefits associated with NOL and tax credit carryforwards on the Consolidated Balance Sheet.

ALLETE and its subsidiaries file a consolidated federal income tax return as well as combined and separate state income tax returns in various jurisdictions. ALLETE has no open federal or state audits, and is no longer subject to federal examination for years before 2017,2018, or state examination for years before 2016.2017. Additionally, the statute of limitations related to the federal tax credit carryforwards will remain open until those credits are utilized in subsequent returns.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL
CONDITION AND RESULTS OF OPERATIONS (Continued)

Financial Overview

The following net income discussion summarizes a comparison of the nine months ended September 30, 2021,2022, to the nine months ended September 30, 2020.2021.

Net income attributable to ALLETE for the nine months ended September 30, 2021,2022, was $107.3$137.6 million, or $2.05$2.48 per diluted share, compared to $127.1$107.3 million, or $2.45$2.05 per diluted share, for the same period in 2020.2021. Net income in 2022 included transaction costs of $2.6 million after-tax, or $0.05 per share, related to the acquisition of New Energy. Net income in 2021 included an approximately $5 million after-tax, or $0.10 per share, negative impact related to ALLETE Clean Energy’s Diamond Spring wind energy facility due to an extreme winter storm event in the southwest United States in February 2021. Earnings per share dilution in 2022 was $0.15 due to additional shares of common stock outstanding as of September 30, 2022.

Regulated Operations net income attributable to ALLETE was $119.4 million for the nine months ended September 30, 2022, compared to $99.4 million for the same period in 2021. Net income at Minnesota Power was higher than 2021 primarily due to the implementation of interim rates on January 1, 2022. These increases were partially offset by higher costs under a PPA with Manitoba Hydro, higher operating and maintenance expense, and lower kWh sales to industrial customers. Our after-tax equity earnings in ATC were lower than 2021 primarily due to period over period changes in ATC’s estimate of a refund liability related to the appeals court decision on MISO return on equity complaints. (See Note 5. Equity Investments.)
ALLETE Clean Energy net income attributable to ALLETE was $15.0 million for the nine months ended September 30, 2022, compared to $11.7 million for the same period in 2021. Net income in 2022 reflected higher wind resources compared to 2021, partially offset by lower realized pricing under the Caddo and Diamond Spring wind energy facilities’ power sales agreements resulting from extreme market volatility and transmission congestion in the Southwest Power Pool. Net income in 2022 also included a reserve for an anticipated loss on sale of ALLETE Clean Energy’s project to repower and sell its Northern Wind project. Net income in 2021 included an approximately $5 million after-tax negative impact related to ALLETE Clean Energy’s Diamond Spring wind energy facility due to an extreme winter storm event in the southwest United States in February 2021. This winter storm event caused volatility in power prices in the regional power market resulting in losses being incurred under one of the facility’s power sales agreements during portions of the winter storm event. Net income in 2020 included margins of $10.2 million after-tax, or $0.20 per share, in Regulated Operations for sales under a 100 MW PSA which expired in April 2020. Net income in 2020 also included reserves for interim rates of $8.3 million after-tax, or $0.16 per share, for the refund of interim rates collected between January 1, 2020, and April 30, 2020.

Regulated Operations net income attributable to ALLETE was $99.4 million for the nine months ended September 30, 2021, compared to $111.0 million for the same period in 2020. Net income at Minnesota Power was lower than 2020 primarily due to: lower margins from Other Power Suppliers resulting from the expiration of a PSA; and higher operating and maintenance, property tax and depreciation expenses. These negative impacts were partially offset by increased earnings related to the GNTL; and higher kWh sales to residential, commercial and municipal customers. Net income in 2020 also included reserves for interim rates of $8.3 million after-tax for the refund of interim rates collected between January 1, 2020, and April 30, 2020. Net income at SWL&P was lower than 2020 primarily due to higher operating expenses. Our after-tax equity earnings in ATC were lower compared to 2020 primarily due to period over period changes in ATC’s estimate of a refund liability related to the FERC decision on MISO return on equity complaints in 2020.
ALLETE Clean Energy net income attributable to ALLETE was $11.7 million for the nine months ended September 30, 2021, compared to $16.8 million for the same period in 2020. Net income in 2021 included an approximately $5 million after-tax negative impact related to ALLETE Clean Energy’s Diamond Spring wind energy facility due to an extreme winter storm event in the southwest United States in February 2021 as well as a lower wind resources at other wind energy facilities. These negative impacts were partially offset by expense management efforts.

Corporate and Other net lossincome attributable to ALLETE was $3.8$3.2 million for the nine months ended September 30, 2021,2022, compared to a net loss of $0.7$3.8 million for the same period in 2020. The net loss2021. Net income in 2021 included2022 reflects higher expenses and additional income tax expense recorded in 2021 as GAAP requires the recognition of income taxes at the estimated annual effective tax rate. These negative impacts were partially offset by earnings from our investment in Nobles 2 due to higher wind resources in 2022, higher land sales at ALLETE Properties, higher tons sold at BNI Energy, and lower income taxes. Net income in 2022 also reflects net income from New Energy of $0.2 million, which commenced operations in December 2020.included a $5.7 million after-tax expense as a result of purchase price accounting related to projects under development at the time of acquisition. These increases were partially offset by transaction costs of $2.6 million after-tax related to the acquisition of New Energy, and higher other expenses compared to 2021.

Operating Revenue Utility increased $49.7$17.8 million from 20202021 primarily due to higherthe implementation of interim rates at Minnesota Power on January 1, 2022, as well as increased recoveries under the Minnesota conservation improvement program. These increases were partially offset by lower fuel adjustment clause recoveries, lower revenue from kWh sales and higher kWh sales.the timing of financial incentives.

Interim retail rates for Minnesota Power, subject to refund, were approved by the MPUC and became effective January 1, 2022, resulting in revenue of $24.9 million. (See Note 2. Regulatory Matters.)

Conservation improvement program recoveries increased $1.9 million from 2021 primarily due to an increase in related expenditures. (See Operating Expenses - Operating and Maintenance.)

Fuel adjustment clause revenue increased $27.4decreased $6.6 million due to higherlower fuel and purchased power costs attributable to retail and municipal customers, and lower kWh sales to retail and municipal customers. (See Fuel, Purchased Power and Gas – Utility.)

Revenue fromLower kWh sales increased $23.6reduced revenue $4.1 million from 20202021 reflecting higherlower sales to commercialretail and industrialmunicipal customers as well as other power suppliers. Sales to commercial and industrial customers increaseddecreased primarily due to improving business conditions relatedlower sales to the COVID-19 pandemic and its impact on customer operations. Manytaconite customers resulting from less taconite production in 2022 compared to 2021, reflecting Cliffs’ Northshore mine being temporarily idled in 2022. (See Outlook - Customers - Northshore Mining.) Sales to residential, commercial and industrialmunicipal customers operated at reduced levels or were temporarily closed or idled duringdecreased from 2021 primarily due to milder weather in the third quarter of 2020 as a result of the COVID-19 pandemic and related governmental responses while business conditions have improved in2022 compared to 2021. These higher sales to commercial and industrial customers were partially offset by lower sales to Verso Corporation which indefinitely idled its paper mill in Duluth, Minnesota in 2020. (See Outlook – Regulated Operations – Industrial Customers and Prospective Additional Load.) Sales to other power suppliers, which are sold at market-based prices into the MISO market on a daily basis or through PSAs of various durations, increaseddecreased in 2022 compared to 2021 primarily due to additional kWh sales made in 2021 to mitigate the uncertainty of customers’ energy needs and potential load loss due to the COVID-19 pandemic.

Revenue from electric sales to taconite customers accounted for 3231 percent of regulated operating revenue in 2021 (292022 (32 percent in 2020)2021). Revenue from electric sales to paper, pulp and secondary wood product customers accounted for 56 percent of regulated operating revenue in 2021 (62022 (5 percent in 2020)2021). Revenue from electric sales to pipelines and other industrial customers accounted for 89 percent of regulated operating revenue in 20212022 (8 percent in 2020)2021).

Financial incentives under the Minnesota conservation improvement program were $2.4 million lower than 2021 due to the timing of MPUC approval, which was received in the second quarter in 2022 compared to the third quarter in 2021. (See Note 2. Regulatory Matters.)

Operating Expenses increased $59.0$6.3 million, or 282 percent, from 2020.2021.

Fuel, Purchased Power and Gas – Utility expense increased $46.7decreased $3.3 million, or 502 percent, from 20202021 primarily due to lower kWh sales, partially offset by higher purchased power prices kWh sales and fuel costs. Fuel and purchased power expense related to our retail and municipal customers is recovered through the fuel adjustment clause.

Transmission Services – Utility expense increased $4.3 million, or 29 percent, from 2020 primarily due to higher MISO-related expense.

Operating and Maintenance expense increased $5.1$9.0 million, or 1117 percent, from 20202021 primarily due to an increase in contract andmore professional services and materials purchased for generation facilities as well as higher conservation improvement program expenses and higher vegetation managementlabor expenses. In addition, 20212022 included higher labor and benefitrate case-related expenses as compared to 2020.

Depreciation and Amortization expense increased $1.3 million, or 3 percent, from 2020 primarily due to additional property, plant and equipment in service.for Minnesota Power’s ongoing rate case. (See Note 2. Regulatory Matters.)

Taxes Other than Income Taxes increased $1.6 million, or 1312 percent from 20202021 primarily due to higher property tax expense resulting from higher estimatedthe impact of an updated estimate of taxable market values.values and rates recorded in 2021.

Equity Earnings decreased $2.2 million, or 42 percent, from 2021 primarily due to period over period changes in ATC’s estimate of a refund liability related to the appeals court decision on MISO return on equity complaints. (See Note 4. Equity Investments.)

Income Tax Benefit was similarlower than 2021 due to 2020 reflectinghigher pre-tax income and lower production tax credits and the timing of income taxes in 2021 compared to 2020, mostly offset by lower pre-tax income. The income tax benefit in 2021 included less income tax benefit recorded in 2021 as GAAP requires the recognition of income taxes at the estimated annual effective tax rate.

Income Taxes – Consolidated

For the quarter ended September 30, 2021,2022, the effective tax rate was a benefit of 25.536.7 percent (benefit of 16.525.5 percent for the quarter ended September 30, 2020)2021). The effective tax rate for 20212022 was a higher benefit primarily due to lower pre-taxthe timing of income partially offset by lower production tax credits.taxes.

We expect our annual effective tax rate in 20212022 to be a lower income tax benefit than in 20202021 primarily due to higher non-controlling interests in subsidiaries, higher pre-tax income, and lower production tax credits, partially offset by investment tax credits. The estimated annual effective tax rate can differ from what a quarterly effective tax rate would otherwise be on a standalone basis, and this may cause quarter to quarter differences in the timing of income taxes.

These increases were partially offset by lower cost recovery rider revenue and higher FERC formula-based rates. Revenue in 2020 also included reserveslower revenue from kWh sales.

Interim retail rates for Minnesota Power, subject to refund, were approved by the refund of interim rates collected betweenMPUC and became effective January 1, 2020,2022, resulting in revenue of $70.5 million. (See Note 2. Regulatory Matters.)

Conservation improvement program recoveries increased $5.6 million from 2021 primarily due to an increase in related expenditures. (See Operating Expenses - Operating and April 30, 2020.Maintenance.)

Lower kWh sales increased $42.6reduced revenue $4.7 million from 20202021 reflecting lower sales to industrial customers and other power suppliers, partially offset by higher sales to residential commercial, industrial and municipalcommercial customers as well as higher pricing on sales to other power suppliers. These increases were partially offset by lower revenue related to the expiration of a 100 MW PSA in April 2020. Sales to commercial and industrial customers increased primarily due to improving business conditions related to the COVID-19 pandemic and its impact on customer operations. Many commercial and industrial customers operated at reduced levels or were temporarily closed or idled during 2020 as a result of the COVID-19 pandemic and related governmental responses while business conditions have improved in 2021. These higher sales to commercial and industrial customers were partially offset by lower sales to and demand revenue from Verso Corporation which indefinitely idled its paper mill in Duluth, Minnesota in 2020. (See Outlook – Regulated Operations – Industrial Customers and Prospective Additional Load.) Sales to residential and municipalcommercial customers increased from 20202021 primarily due to more favorablecolder weather conditions in 20212022 compared to 2020.2021. Sales to industrial customers decreased primarily due to lower sales to taconite customers resulting from less taconite production in 2022 compared to 2021, reflecting Cliffs’ Northshore mine being temporarily idled in 2022.

Operating Revenue increased $6.9$5.6 million, or 139 percent, from 20202021 primarily due to revenue from the South Peak and Diamond Spring wind energy facilities which commenced operations in April 2020 and December 2020, respectively, partially offset byabsence of the negative impact related to ALLETE Clean Energy’s Diamond Spring wind energy facility due toresulting from an extreme winter storm event in the southwest United States in February 2021.2021 as well as higher wind resources at other wind energy facilities. Operating revenue in 2022 was also impacted by lower realized pricing under the Caddo and Diamond Spring wind energy facilities’ power sales agreements resulting from extreme market volatility and transmission congestion in the Southwest Power Pool.

Cost of Sales – Non-utility increased $14.2 million from 2021 reflecting a $10.2 million reserve in the second quarter of 2022 related to the sale of ALLETE Clean Energy’s project to repower and sell its Northern Wind project, which was fully offset by a gain on removal of the PSA liability for the Northern Wind project upon decommissioning of the wind energy facilities. (See Other Income and Outlook – ALLETE Clean Energy.) In addition, Cost of Sales Non-utility in 2022 reflected an additional $4.0 million reserve in the third quarter of 2022 for an anticipated loss on sale of ALLETE Clean Energy’s Northern Wind project resulting from inflationary increases and significant cost pressures.

Operating and Maintenance expense increased $4.8$5.0 million, or 1816 percent, from 20202021 primarily due to operating and maintenance expenses related to the South Peak and Diamond SpringCaddo wind energy facilities. These increases were offset by expense management efforts.facility, which commenced operations in December 2021.

Income Tax Benefit decreased $3.3 million from 2021 primarily due to higher net loss attributable to non-controlling interest.

Net Loss Attributable to Non-Controlling Interest increased $22.2 million from 2021 reflecting net losses attributable to non-controlling interest for the Caddo wind energy facility as well as higher net losses attributable to non-controlling interests for the Glen Ullin, South Peak and Diamond Spring wind energy facilities resulting from higher wind resources and a higher PTC value in 2022 compared to 2021.

Corporate and Other

Operating Revenue decreased $2.4increased $47.0 million, or 365 percent, from 2020 primarily due2021 reflecting revenue from New Energy, which was acquired in April 2022, higher land sales at ALLETE Properties compared to lower2021 and higher revenue at BNI Energy, which operates under cost-plus fixed fee contracts, as a result of lowerhigher expenses and fewermore tons sold in 20212022 compared to 2020 as well as lower land sales at ALLETE Properties in 2021.

Net LossIncome Attributable to ALLETE was $3.8$3.2 million in 20212022 compared to a net loss of $0.7$3.8 million in 2020. The net loss2021. Net income in 2021 included2022 reflects higher expenses and additional income tax expense recorded in 2021 as GAAP requires the recognition of income taxes at the estimated annual effective tax rate. These negative impacts were partially offset by earnings from our investment in Nobles 2 which commenced operationsdue to higher wind resources in December 2020. Net income2022, higher land sales at ALLETE Properties, higher tons sold at BNI Energy, was $5.2and lower income taxes. Net income in 2022 also reflects net income from New Energy of $0.2 million, in 2021which included a $5.7 million after-tax expense as a result of purchase price accounting related to projects under development at the time of acquisition. These increases were partially offset by transaction costs of $2.6 million after-tax related to the acquisition of New Energy, and higher other expenses compared to net income of $5.3 million in 2020. The net loss at ALLETE Properties was $1.5 million in 2021 compared to a net loss of $1.7 million in 2020.2021.

Income Taxes – Consolidated

For the nine months ended September 30, 2021,2022, the effective tax rate was a benefit of 27.626.0 percent (benefit of 30.127.6 percent for the nine months ended September 30, 2020)2021). The effective tax rate for 20212022 was a lower benefit primarily due to higher pre-tax income and higher net losses attributable to non-controlling interest and lower production tax credits.interests in subsidiaries.

We expect our annual effective tax rate in 20212022 to be a lower income tax benefit as compared to 2020than in 2021 primarily due to higher net losses attributable to non-controlling interestinterests in subsidiaries, higher pre-tax income and lower production tax credits, partially offset by investment tax credits. The estimated annual effective tax rate can differ from what a quarterly effective tax rate would otherwise be on a standalone basis, and this may cause quarter to quarter differences in the timing of income taxes. (See Note 8.9. Income Tax Expense.)


CRITICAL ACCOUNTING POLICIES

Certain accounting measurements under GAAP involve management’s judgment about subjective factors and estimates, the effects of which are inherently uncertain. Accounting measurements that we believe are most critical to our reported results of operations and financial condition include: regulatory accounting, pension and postretirement health and life actuarial assumptions, valuation of business combinations and resulting goodwill, impairment of long-lived assets, and taxation. These policies are reviewed with the Audit Committee of our Board of Directors on a regular basis and summarized in Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations of our 20202021 Form 10-K. As a result of our acquisition of New Energy on April 15, 2022, the valuation of business combination and resulting goodwill is considered a critical accounting policy.

Valuation of Business Combinations and Resulting Goodwill. When we acquire a business, the assets acquired and liabilities assumed are recorded at their respective fair values as of the acquisition date. Determining the fair value of intangible assets acquired as part of a business combination requires us to make significant estimates. These estimates may include the amount and timing of projected future cash flows, the discount rate used to discount those cash flows to present value, the assessment of the asset’s life cycle, and the consideration of legal, technical, regulatory, economic and competitive risks.

ALLETE, Inc. Third Quarter 20212022 Form 10-Q
3739



CRITICAL ACCOUNTING POLICIES (Continued)

Goodwill. Goodwill is the excess of the purchase price (consideration transferred) over the estimated fair value of net assets of acquired businesses. In accordance with GAAP, goodwill is not amortized. The Company assesses whether there has been an impairment of goodwill annually in the fourth quarter and whenever an event occurs or circumstances change that would indicate the carrying amount may be impaired. Impairment testing for goodwill is done at the reporting unit level. An impairment loss is recognized when the carrying amount of the reporting unit’s net assets exceeds the estimated fair value of the reporting unit. The test for impairment requires us to make several estimates about fair value, most of which are based on projected future cash flows. Our estimates associated with the goodwill impairment test are considered critical due to the amount of goodwill recorded on our Consolidated Balance Sheet and the judgment required in determining fair value, including projected future cash flows.


OUTLOOK

ALLETE is an energy company committed to earning a financial return that rewards our shareholders, allows for reinvestment in our businesses, and sustains growth. The Company has a long-term objective of achieving consolidated average annual earnings per share growth within a range of 5 percent to 7 percent.

ALLETE is predominately a regulated utility through Minnesota Power, SWL&P, and an investment in ATC. ALLETE’s strategy is to remain predominately a regulated utility while investing in ALLETE Clean Energy and New Energy and its Corporate and Other businesses to complement its regulated businesses, balance exposure to the utility’s industrial customers, and provide potential long-term earnings growth. ALLETE expects net income from Regulated Operations to be approximately 80 percent of total consolidated net income in 2021.2022. Over the next several years, the contribution ofALLETE expects increased contributions to net income from ALLETE Clean Energy, New Energy, and its Corporate and Other businesses to net income is expected to increase as ALLETE grows these operations. ALLETE expects its businesses to generally provide regulated, contracted or recurring revenues, and to support sustained growth in net income and cash flow.

On August 16, 2022, the Inflation Reduction Act was signed into law. We believe our businesses will benefit from certain provisions of the legislation including from the extension and transferability of production tax credits and investment tax credits, among others. We do not anticipate any impact from the new alternative minimum tax. We will continue to assess the impact of the legislation as additional implementation guidance becomes available.

Regulated Operations. Minnesota Power’s long-term strategy is to be the leading electric energy provider in northeastern Minnesota by providing safe, reliable and cost-competitive electric energy, while complying with environmental permit conditions and renewable energy requirements. Keeping the cost of energy production competitive enables Minnesota Power to effectively compete in the wholesale power markets and minimizes retail rate increases to help maintain customer viability. As part of maintaining cost competitiveness, Minnesota Power intends to reduce its exposure to possible future carbon and GHG legislation by reshaping its generation portfolio, over time, to reduce its reliance on coal. Minnesota Power has a goal of delivering 100 percent carbon-free energy by 2050. (See EnergyForward.) We will monitor and review proposed environmental regulations and may challenge those that add considerable cost with limited environmental benefit. Minnesota Power will continue to pursue customer growth opportunities and cost recovery rider approvals for transmission, renewable and environmental investments, as well as work with regulators to earn a fair rate of return.

Minnesota Power also submitted its IRP with the MPUC on February 1, 2021. The outcome of this IRP is likely to be instrumental in the evolution of our EnergyForward strategic plan that provides for significant emission reductions and diversifying our electricity generation mix to include more renewables, and is expected to provide potential earnings growth over the long-term. (See EnergyForward.)

Regulatory Matters. Entities within our Regulated Operations segment are under the jurisdiction of the MPUC, FERC, PSCW and NDPSC. See Note 2. Regulatory Matters for discussion of regulatory matters within these jurisdictions.

2022 Minnesota General Rate Case. On November 1, 2021, Minnesota Power filed a retail rate increase request with the MPUC seeking an average increase of approximately 18 percent for retail customers. The rate filing seeks a return on equity of 10.25 percent and a 53.81 percent equity ratio. On an annualized basis, the requested final rate increase would generate approximately $108 million in additional revenue. OnceIn orders dated December 30, 2021, the MPUC accepted the filing is accepted as complete and authorized an annual interim rate increase ofbeginning January 1, 2022, with approximately $87$80 million subject to refund, which would be an average increase of approximately 14 percent for retail customers, is expected to be implemented within 60 days, subject to MPUC adjustmentcollected in cash and authorization. We cannot predict the levelapproximately $8 million of interim orrates for residential customers deferred with a final rates that may be authorized bydetermination on recovery at the MPUC.end of the rate case.

Minnesota Power Land Sales. In August 2020, Minnesota Power filed a petition with the MPUC for approval to sell land that surrounds several reservoirs on its hydroelectric system and is no longer required to maintain its operations. The land has an estimated value of approximately $100 million, and Minnesota Power proposed to credit ratepayers the net proceeds from the sales in a future rate case or through its renewable resources rider to mitigate future rate increases. At a hearing on October 14, 2021, the MPUC decided to allow the land sales to occur and the proceeds refunded to ratepayers subject to certain conditions and required compliance filings.

OUTLOOK (Continued)
Regulated Operations (Continued)

On September 1, 2022, the administrative law judge (ALJ) issued a report containing recommendations that if adopted in whole by the MPUC would result in an increase in rates of approximately $76 million on an annualized basis. On September 23, 2022, Minnesota Power filed exceptions totaling approximately $30 million to the ALJ’s report contesting certain recommendations. A final decision by the MPUC is expected in early 2023. Management has evaluated the need for a reserve for interim rate refunds and concluded that a reserve is not necessary as of September 30, 2022. We cannot predict the level of final rates that may be authorized by the MPUC.

2022 Wisconsin General Rate Case. On June 1, 2022, SWL&P refiled its rate increase request with the PSCW seeking an average increase of 3.6 percent for retail customers. The filing seeks an overall return on equity of 10.4 percent and a 55 percent equity ratio. On an annualized basis, the requested final rate increase would generate approximately $4.3 million in additional revenue.

Industrial and Municipal Customers and Prospective Additional Load.

Industrial Customers. Electric power is one of several key inputs in the taconite mining, paper, pulp and secondary wood products, pipeline and other industries. Approximately 4751 percent of our regulated utility kWh sales in the nine months ended September 30, 2021,2022, were made to our industrial customers (49(47 percent in the nine months ended September 30, 2020)2021).

Taconite. Minnesota Power’s taconite customers are capable of producing up to approximately 41 million tons of taconite pellets annually. Taconite pellets produced in Minnesota are primarily shipped to North American steel making facilities that are part of the integrated steel industry, which continue to lead the world in environmental performance among steelmaking countries. According to the U.S. Department of Energy, steel production in the U.S. is the most energy efficient of any major steel producing country. Steel produced from these North American facilities is used primarily in the manufacture of automobiles, appliances, tubular applications for all industries, and in the construction industry. Steel is also a critical component of the clean energy transformation underway today. Meeting the demand for more renewable energy and the need for additional infrastructure to transport green energy from the point of generation to the end user both require steel. Historically, less than 10 percent of Minnesota taconite production has been exported outside of North America.

There has been a general historical correlation between U.S. steel production and Minnesota taconite production. The American Iron and Steel Institute, an association of North American steel producers, reported that U.S. raw steel production operated at approximately 81 percent of capacity during the first nine months of 2021 compared to 66 percent in the first nine months of 2020. The World Steel Association, an association of steel producers, national and regional steel industry associations, and steel research institutes representing approximately 85 percent of world steel production, projected in October 2021 that U.S. steel consumption will increase in 2021 by approximately 15 percent compared to 2020 as well as increase in 2022 by approximately 6 percent compared to 2021.

Minnesota Power’s taconite customers may experience annual variations in production levels due to such factors as economic conditions, short-term demand changes or maintenance outages. We estimate that a one million ton change in Minnesota Power’s taconite customers’ production would impact our annual earnings per share by approximately $0.04, net of expected power marketing sales at current prices. Changes in wholesale electric prices or customer contractual demand nominations could impact this estimate. Minnesota Power proactively sells power in the wholesale power markets that is temporarily not required by industrial customers to optimize the value of its generating facilities. Long-term reductions in taconite production or a permanent shut down of a taconite customer may lead Minnesota Power to file a general rate case to recover lost revenue.

USS Corporation. In April 2020, USS Corporation stated it would idle its Keetac facility in Keewatin, Minnesota, in response to the sudden and dramatic decline in business conditions resulting from the COVID-19 pandemic. In addition, in May 2020, USS Corporation announced that production was expected to be temporarily reduced at its Minntac Plant in Mountain Iron, Minnesota. USS Corporation resumed normal production at its Minntac Plant beginning in late July 2020 and resumed operations at its Keetac facility in December 2020. In October 2021, USS Corporation announced that it will be increasing its blast furnace operating rates at its Gary, Indiana steel mill through the installation of a 500,000 ton per year pig iron caster.When completed in early 2023, this pig iron produced from Minnesota iron ore would be used at USS Corporation’s Big River steel making facility in Osceola, Arkansas. USS Corporation has the capability to produce approximately 15 million and 5 million tons annually at its Minntac and Keetac plants, respectively.

Cliffs. In December 2020, Cliffs announced that it had completed the previously announced acquisition of substantially all of the operations of ArcelorMittal USA LLC and its subsidiaries. Cliffs had stated that upon closure of the acquisition Cliffs would be the largest flat-rolled steel producer and the largest iron ore pellet producer in North America. The acquisition included ArcelorMittal’s Minorca mine in Virginia, Minnesota, and its ownership share of Hibbing Taconite in Hibbing, Minnesota, which are both large industrial customers of Minnesota Power. Cliffs is now Minnesota Power’s largest customer. The acquisition has increased customer concentration risk for the Company and could lead to further capacity consolidation for both steel blast furnaces and the related Minnesota iron ore production.

Cliffs completed construction of a hot briquetted iron production plant in Toledo, Ohio, in 2020, which has utilized direct reduced-grade pellets from Northshore Mining. In October 2021, Cliffs indicated it plans to move direct reduced-grade pellet production to its Minorca mine and that Northshore Mining would become a “swing facility” due to the highhigher royalty rates at its Babbitt, Minnesotathat mine. No announcement was made on the timing of this change in operation or the amount of investment required at Minorca to transition to this new product for ultimate use in its blast furnaces.

Northshore Mining. Cliffs completed construction of a hot briquetted iron production plant in Toledo, Ohio, in 2020, which utilizes direct reduced-grade pellets from Northshore Mining. In April 2020,On February 11, 2022, Cliffs announced that based on market conditions, it would be temporarily idling Northshore Mining.with the use of additional scrap in its basic oxygen furnaces, its iron ore needs are not as high as before.

Cliffs has also indicated that going forward it will be limiting the facility in August 2020.tonnage of iron ore pellets sold to third parties. Northshore Mining has the capability to produce approximately 6 million tons annually. Minnesota Power has a PSA through 2031 with Silver Bay Power, which provides the majority of the electric service requirements for Northshore Mining. (See Silver Bay PowerCliffs.)

Silver Bay PowerUSS Corporation. In 2016, Minnesota Power and Silver Bay Power entered into USS Corporation has announced plans to invest approximately $150 million to construct a PSA through 2031.

Startingproducing direct reduced-grade (DR-grade) pellets at its Keetac plant. USS Corporation broke ground on the project in 2016, Minnesota Power supplied Silver Bay Power with at least 50 MW of energy and Silver Bay Power had the option to purchase additional energy from Minnesota Power as it transitioned away from self-generation. In the third quarter of 2019, Silver Bay Power ceased self-generation and Minnesota Power began supplying the full energy requirements for Silver Bay Power.

Hibbing Taconite. In April 2020, ArcelorMittal announced that Hibbing Taconite in Hibbing, Minnesota, would idle production due to the COVID-19 pandemic. Hibbing Taconite resumed normal production in August 2020. Hibbing Taconite’s current mineable ore reserves are2022, which is expected to be exhaustedcompleted and producing DR-grade pellets in 2025.

USS Corporation’s Minntac and resumed managementKeetac plants are large power industrial customers of Hibbing Taconite, has stated that it has a plan to extend the mine life of Hibbing Taconite with ore reserves already under control of Cliffs. There are ample ore reserves in northeastern Minnesota that could supply operations for decades to come, and Minnesota Power’s taconite customers routinely develop and extend their mine plans to optimize assets. Hibbing TaconitePower. USS Corporation has the capability to produce approximately 815 million and 5 million tons annually.annually at its Minntac and Keetac plants, respectively.

Minnesota Sulfate Wild Rice Water Quality Standard. On April 29, 2021, the EPA identified rivers and lakes in Minnesota in which wild rice grows that have sulfate levels that exceed Minnesota’s sulfate limit for wild rice waters. On September 1, 2021, three additional wild rice waters with sulfate levels that exceed Minnesota’s sulfate limit were identified. The EPA directed the MPCA to add these rivers and lakes to its list of impaired waters which can be used to set limits in discharge permits for industrial activities such as mining. Minnesota Power’s taconite customers could be adversely impacted if they are required to significantly reduce sulfate discharges.

ST Paper Pulp and Secondary Wood Products. The North American paper and pulp industry faces declining demand due to the impact of electronic substitution for print and changing customer needs. As a result, certain paper and pulp customers have reduced their existing operations in recent years and have pursued or are pursuing product changes in response to the declining demand. We expect operating levels in 2021 at the four major paper and pulp mills we serve to be lower than 2020 primarily due to the indefinite idling of Verso Corporation’s paper mill in Duluth, Minnesota. (See Verso Corporation.)

Verso Corporation. In June 2020, Verso Corporation indefinitely idled its paper mill in Duluth, Minnesota (Duluth Mill). Verso Corporation statedMay 2021, ST Paper announced it had completed the decision was due to the accelerated decline in graphic paper demand resulting from the COVID-19 pandemic and has disclosed it is considering options for the Duluth Mill, including marketing for a sale. On January 29, 2021, Verso Corporation provided notice of termination for its contract effective in January 2025, with no demand charge expected after February 2023 (minimal demand charge through January 2023). On May 17, 2021, Verso Corporation announced the completion of the salepurchase of the Duluth Mill tofrom Verso Corporation. ST Paper LLC. At that time, ST Paper LLChas stated it plans to convert the Duluth Mill to produce tissue. In January 2022, Minnesota Power entered into an electric service agreement with ST Paper that would begin Large Power customer service with a minimum term of six years upon start-up of operations, which is anticipated in 2023. A petition for approval of the electric service agreement was approved by the MPUC in February 2022. Upon start-up of operations, ST Paper will become a Large Power customer as we expect to serve requirements of at least 10 MW of customer load.

On August 2, 2021,Hibbing Public Utilities. In April 2022, Minnesota Power filedentered into a petitionnew long-term Power Purchase and Market Energy Service Agreement with the MPUC requesting the MPUC to interpret the electric service agreement (ESA) between Minnesota Power and Verso Corporation finding that Verso Corporation has tariff obligations and owes minimum firm demand payments during the term of the ESA. Minnesota Power filed this petition in response to Verso Corporation ceasing to make its minimum firm demand payments under the ESA. At a hearing on October 14, 2021, the MPUC agreed with Minnesota Power’s petition and concluded that the MPUC has jurisdiction to interpret the relevant provisions of the ESA, and the ESA requires Verso Corporation to continue full minimum firm demand paymentsHibbing Public Utilities for athe period of two years fromJune 1, 2022, through May 31, 2027. The agreement replaces the January 29, 2021, notice of termination, regardless of2015 Electric Services Agreement between Hibbing Public Utilities and Minnesota Power’s electricity sales to a new customer at the former Verso Corporation facility. Minnesota Power has a receivable related to the ESA of approximately $1.2 million as of September 30, 2021. In addition, Verso Corporation owes Minnesota Power payments under a steam agreement, which is proceeding through arbitration. Minnesota Power has a receivable under the steam agreement of approximately $2.4 million as of September 30, 2021. Minnesota Power expects to fully collect these outstanding account receivable balances as well as Verso Corporation’s remaining obligations under the ESA.

Pipeline and Other Industries.

Husky Energy. In 2018, a fire at Husky Energy’s refinery in Superior, Wisconsin, disrupted operations at the facility. Under normal operating conditions, SWL&P provides approximately 14 MW of average monthly demand to Husky Energy in addition to water service. In 2019, Husky Energy announced that it had received the required permit approvals to begin reconstruction. In June 2020, Husky Energy announced that rebuild construction at the refinery had resumed following a suspension in March 2020 due to the COVID-19 pandemic. The facility remains at minimal operations, and the refinery is not expected to resume normal operations until 2023. In October 2020, Husky Energy announced a transaction to combine with Cenovus Energy Inc., which closed in the first quarter of 2021.

Prospective Additional Load.Minnesota Power is pursuing new wholesale and retail loads in and around its service territory. Currently, several companies in northeastern Minnesota continue to progress in the development of natural resource-based projects that represent long-term growth potential and load diversity for Minnesota Power. We cannot predict the outcome of these projects.

PolyMet. PolyMet is planning to start a new copper-nickel and precious metal (non-ferrous) mining operation in northeastern Minnesota. In 2015, PolyMet announced the completion of the final EIS by state and federal agencies, which was subsequently published in the Federal Register and Minnesota Environmental Quality Board Monitor. The Minnesota Department of Natural Resources (DNR) and the U.S. Army Corps of Engineers have both issued final Records of Decision, finding the final EIS adequate.

PolyMet was issued all necessary permits to construct and operate its new mining operation; however, in early 2020, the Minnesota Court of Appeals reversed decisions granting PolyMet’s permit to mine, dam-safety permits and air permits. PolyMet filed petitions for further review with the Minnesota Supreme Court seeking to overturn the Minnesota Court of Appeals decisions. In February 2021, the Minnesota Supreme Court overturned a decision by the Minnesota Court of Appeals that had remanded the air permit back to the MPCA and returned the case to the Minnesota Court of Appeals. On July 19, 2021, the Minnesota Court of Appeals remanded PolyMet’s air permit to the MPCA seeking additional explanation supporting the MPCA’s permitting decision. On March 8, 2021, the U.S. District Court of Minnesota granted an EPA request to conduct a 90-day review of downstream water quality under Section 401(a)(2) of the Clean Water Act. Given the EPA's downstream water quality determination is necessary for PolyMet's federal Section 404 wetlands permit, on March 17, 2021, the U.S. Army Corps of Engineers notified PolyMet it had suspended the permit for the duration of the EPA's review. On April 28, 2021, the Minnesota Supreme Court reversed the Minnesota Court of Appeals decision on the dam-safety permits while also upholding its decision on PolyMet’s permit to mine. The decision requires the DNR to hold a contested case hearing regarding the effectiveness of bentonite clay capping for eventual closure of PolyMet’s planned tailings basin and to also determine a fixed term for the permit to mine. Minnesota Power could supply between 45 MW and 50 MW of load under a 10-year power supply contract with PolyMet that would begin upon start-up of operations.

EnergyForward. Minnesota Power is executing EnergyForward, its strategy assuring reliability, protecting affordability and further improving environmental performance. The plan includes completed and planned investments in wind, solar, natural gas and hydroelectric power, construction of additional transmission capacity, the installation of emissions control technology and the idling and retirement of certain coal-fired generating facilities. Minnesota Power has a vision to deliver 100 percent carbon-free energy to customers by 2050, continuing its commitment to climate, customers and communities through its EnergyForward strategy. This vision builds on Minnesota Power’s recent achievement of now providing 50 percent renewable energy to its customers.

2021 Integrated Resource Plan. On February 1, 2021, Minnesota Power filed its latest IRP with the MPUC, which outlines its clean-energy transition plans through 2035. These plans include expanding its renewable energy supply to 70 percent by 2030, achieving coal-free operations at its facilities by 2035, and investing in a resilient and flexible transmission and distribution grid. Minnesota Power has also set a target to achieve an 80 percent reduction in carbon emissions by 2035 compared to 2005 levels. As part of these plans, Minnesota Power anticipates adding approximately 400 MW of new wind and solar energy resources, retiring Boswell Unit 3 by 2030 and transforming Boswell Unit 4 to be coal-free by 2035.

EnergyForward (Continued)

In recent years, Minnesota Power has transformed its energy supply from more than a 95 percent reliance on coal to become a leader in the nation’s clean-energy transformation. Since 2013, the company has closed or converted seven of its nine coal-fired units and added nearly 900 megawatts of renewable energy sources. Additionally, Minnesota Power has been a leader in energy conservation, surpassing the state’s conservation goals each year for the past decade.

Nemadji Trail Energy Center.Transmission.In 2017, Minnesota Power submitted a resource package to the MPUC which included requesting approval of a natural gas capacity dedication and other affiliated-interest agreements for NTEC, an approximately 600 MW proposed combined-cycle natural gas-fired generating facility to be built in Superior, Wisconsin, which will be jointly owned by Dairyland Power Cooperative, Basin and South Shore Energy, ALLETE’s non-rate regulated, Wisconsin subsidiary. Minnesota Power is expected to purchase approximately 20 percent of the facility's output starting in 2025 pursuant to the capacity dedication agreement.

Renewable Energy. Minnesota Power continues to execute its renewable energy strategy and expects approximately 50 percent of its energy will be supplied by renewable energy sources in 2021. Minnesota Power also has a goal of delivering 100 percent carbon-free energy by 2050. (See EnergyForward.)

Wind Energy. Minnesota Power’s wind energy facilities consist of Bison (497 MW) located in North Dakota, and Taconite Ridge (25 MW) located in northeastern Minnesota. Minnesota Power also has two long-term wind energy PPAs with an affiliate of NextEra Energy, Inc. to purchase the output from Oliver Wind I (50 MW) and Oliver Wind II (48 MW) located in North Dakota.

Minnesota Power uses the 465-mile, 250-kV DC transmission line that runs from Center, North Dakota, to Duluth, Minnesota, to transport wind energy from North Dakota while gradually phasing out coal-based electricity delivered to its system over this transmission line from Square Butte’s lignite coal-fired generating unit. Minnesota Power is currently pursuing a modernization and capacity upgrade of its DC transmission system to continue providing reliable operations and additional system capabilities.

Minnesota Power has an approved cost recovery rider for certain renewable investments and expenditures. The cost recovery rider allows Minnesota Power to charge retail customers on a current basis for the costs of certain renewable investments plus a return on the capital invested. Updated customer billing rates were approved by the MPUC in an order dated December 10, 2020.

Nobles 2 PPA. Minnesota Power has a long-term PPA with Nobles 2 that provides for Minnesota Power to purchase the energy and associated capacity from a 250 MW wind energy facility in southwestern Minnesota through 2040. The agreement provides for the purchase of output from the facility at fixed energy prices. There are no fixed capacity charges, and Minnesota Power will only pay for energy as it is delivered. (See Corporate and Other – Investment in Nobles 2.)

Manitoba Hydro.MISO Long Range Transmission Plan. Minnesota Power has three long-term PPAs with Manitoba Hydro. Underand Great River Energy announced on July 25, 2022, their intent to build a 150-mile, 345-kV transmission line, connecting northern Minnesota to central Minnesota to support continued reliability in the first PPA, Minnesota Power is purchasing surplus energy through April 2022. This energy-only agreement primarily consists of surplus hydro energy on Manitoba Hydro’s system that is delivered to Minnesota Power onUpper Midwest. Great River Energy, a non-firm basis. Under this agreement, Minnesota Power will purchase at least one million MWh of energy over the contract term. The second PPA provides for Minnesota Power to purchase 250 MW of capacitywholesale electric power cooperative, and energy from Manitoba Hydro through May 2035. The third PPA provides for Minnesota Power to purchase up to 133 MW of energy from Manitoba Hydro through June 2040.

Solar Energy. Minnesota Power’s solar energy supply consists of Camp Ripley, a 10 MW solar energy facility at the Camp Ripley Minnesota Army National Guard base and training facility near Little Falls, Minnesota, and a community solar garden in northeastern Minnesota, which is comprised of a 1 MW solar array owned and operated by a third party with the output purchased by Minnesota Power and a 40 kW solar array that is owned and operated by Minnesota Power. SWL&P also plans to construct a 470 kW solar array as part of a community solar garden in Superior, Wisconsin, which was approved by the PSCW in October 2020.

In June 2020, Minnesota Power filed a proposalNotice of Intent to Construct, Own and Maintain the transmission line with the MPUC on August 1, 2022. This joint project is part of a portfolio of transmission projects approved on July 25, 2022, by MISO, as part of the first phase of its Long Range Transmission Plan. Planning for the $970 million transmission line is in its early stages with the route anticipated to accelerate plans for solar energy with an estimated $40 million investment in approximately 20 MWgenerally follow existing rights of solar energy projects in Minnesota which was approvedway in an order dated June 29, 2021.

Minnesota Power has approval for currentestablished power line corridor. The two utilities expect to seek a combined Certificate of Need and Route Permit from the MPUC. The MPUC will determine the final route as well as cost recovery for Minnesota Power’s approximately 50 percent estimated share of investments and expenditures relatedthe project. Subject to compliance with the Minnesota Solar Energy Standard. In June 2020, Minnesota Power filed a petition seeking MPUC approval of a customer billing rate for solar costs related to investments and expenditures for meeting the state of Minnesota’s solar energy standard, which were approved by the MPUC at a hearing on April 14, 2021. New customer billing rates for the solar cost recovery rider were implemented on June 1, 2021.

Transmission. We continue to make investments in transmission opportunities that strengthen or enhanceregulatory approvals, the transmission grid or take advantage of our geographical location between sources of renewable energy and end users. These include the GNTL, investmentsline is expected to enhance our own transmission facilities, investmentsbe in other transmission assets (individually orservice in combination with others) and our investment in ATC.

Great Northern Transmission Line. As a condition of the 250 MW long-term PPA entered into with Manitoba Hydro, construction of additional transmission capacity was required. As a result, Minnesota Power constructed the GNTL, an approximately 220‑mile 500-kV transmission line between Manitoba and Minnesota’s Iron Range that was proposed by Minnesota Power and Manitoba Hydro in order to strengthen the electric grid, enhance regional reliability and promote a greater exchange of sustainable energy. In June 2020, Minnesota Power placed the GNTL into service with project costs of approximately $310 million incurred by Minnesota Power. Total project costs, including those costs contributed by a subsidiary of Manitoba Hydro, totaled approximately $660 million. Also in June 2020, Manitoba Hydro placed the MMTP into service. The 250 MW PPA with Manitoba Hydro commenced when the GNTL was placed into service.2030.

Investment in ATC. Our wholly-owned subsidiary, ALLETE Transmission Holdings, owns approximately 8 percent of ATC, a Wisconsin-based utility that owns and maintains electric transmission assets in portions of Wisconsin, Michigan, Minnesota and Illinois. We account for our investment in ATC under the equity method of accounting. (See Note 3. Equity Investments.) As of September 30, 2021, our equity investment in ATC was $153.0 million ($149.0 million as of December 31, 2020).

ATC’s authorized return on equity is 10.02 percent, or 10.52 percent including an incentive adder for participation in a regional transmission organization, based on a May 2020 FERC order that granted rehearing of a 2019 FERC order. These FERC orders are subject to various outstanding legal challenges related to the refund period ordered by the FERC. If these legal challenges are successful, ATC may be required to provide refunds to its customers of up to approximately $66 million of which our share would be approximately $5 million pre-tax.

ATC’s 10-year transmission assessment, which covers the years 20202022 through 2029,2031, identifies a need for between $2.9$5.1 billion and $3.5$6.2 billion in transmission system investments. These investments by ATC, if undertaken, are expected to be funded through a combination of internally generated cash, debt and investor contributions. As opportunities arise, we plan to make additional investments in ATC through general capital calls based upon our pro rata ownership interest in ATC.

ALLETE Clean Energy.

ALLETE Clean Energy focuses on developing, acquiring, and operating clean and renewable energy projects. ALLETE Clean Energy currently owns and operates, in seven states, more than 1,000 MW of nameplate capacity wind energy generation that is contracted under PSAs of various durations. In addition, ALLETE Clean Energy currently has an approximately 300 MW wind energy facility under construction. ALLETE Clean Energy also engages in the development of wind energy facilities to operate under long-term PSAs or for sale to others upon completion.

ALLETE Clean Energy believes the market for renewable energy in North America is robust, driven by several factors including environmental regulation, tax incentives such as the extension of production tax credit and investment tax credits, societal expectations and continual technology advances. State renewable portfolio standards, state or federal regulations to limit GHG emissions and the extension of production tax credit and investment tax credits are examples of environmental regulation or public policy that we believe will drive renewable energy development.

ALLETE Clean Energy’s strategy includes the safe, reliable, optimal and profitable operation of its existing facilities. This includes a strong safety culture, the continuous pursuit of operational efficiencies at existing facilities and cost controls. ALLETE Clean Energy generally acquires facilities in liquid power markets and its strategy includes the exploration of PSA extensions upon expiration of existing contracts, production tax credit requalification of existing facilities or the sale of facilities.

OUTLOOK (Continued)
ALLETE Clean Energy (Continued)

ALLETE Clean Energy will pursue growth through acquisitions or project development. ALLETE Clean Energy is targeting acquisitions of existing operating portfolios which have a mix of long-term PSAs in place and/or available for repowering and recontracting. Further, ALLETE Clean Energy will evaluate actions that will lead to the addition of complimentary clean energy products and services. At this time, ALLETE Clean Energy expectsis focused on actions that will optimize its clean energy project portfolio of operating and development projects, which may include recontracting, repowering, entering into partnerships and divestitures along with continued acquisitions or development of new facilities will be primarilyprojects including wind, solar, energy storage or storage ready facilities across North America. ALLETE Clean Energy is also targeting the development of new facilities up to 300 MW each, which will have long-term PSAs in place for the output or may be sold upon completion.

Portions of our ALLETE Clean Energy business are experiencing return pressures that are impacting our earnings per share growth from increased competition, and lower forward price curves, as a growing amount of investment capital is being directed into wind generation opportunities. In addition, current and potential new project developments can be negatively affected by a lower ALLETE stock price, which may result in such projects not being accretive, or otherwise unable to satisfy our financial objectives criteria to proceed. In response to these market pressures, we are actively evaluating additional growth opportunities to deliver more comprehensive clean energy solutions for customers at ALLETE Clean Energy, which may include solar, storage solutions, and related energy infrastructure investments and services. We believe that the renewable energy industry is entering a new phase of growth and that we are well-positioned to serve customers and drive future growth at ALLETE. ALLETE Clean Energy will continue to optimize its existing wind energy facility portfolio, seek development of its remaining safe harbor inventory of tax credit qualified turbines, and explore other renewable energy opportunities to expand its service offerings to further enhance its growth and profitability.

Federal production tax credit qualification is important to the economics of project development, and ALLETE Clean Energy has invested in equipment to meet production tax credit safe harbor provisions which provides an opportunity to seek development of its remaining safe harbor production tax credit qualified equipment through 2025 based on the most recent PTC safe harbor extension by the IRS. ALLETE Clean Energy has completed its investment of approximately $80 million for production tax credit requalification of approximately 470 WTGs at its Storm Lake I, Storm Lake II, Lake Benton and Condon wind energy facilities. We anticipate annual production tax credits relating to these projects of approximately $20 million annually through 2027 and decreasing thereafter through 2030. Disruptions in our supply chains or a lack of available financing resulting from the ongoing COVID-19 pandemic, if they occur, could jeopardize our ability to complete certain capital projects in time to qualify them for production tax credits. To date we have not experienced disruptions in our supply chains related to the COVID-19 pandemic.

In March 2020, ALLETE Clean Energy acquired the rights to the approximately 300 MW Caddo wind development project in Oklahoma from Apex Clean Energy. The Caddo wind project is fully contracted to sell wind power under long-term power sales agreements. Construction is expected to be completed in late 2021.

OTHER

Environmental Matters.

Our businesses are subject to regulation of environmental matters by various federal, state and local authorities. A number of regulatory changes to the Clean Air Act, the Clean Water Act and various waste management requirements have been promulgated by both the EPA and state authorities over the past several years. Minnesota Power’s facilities are subject to additional requirements under many of these regulations. Minnesota Power is reshaping its generation portfolio, over time, to reduce its reliance on coal, has installed cost-effective emission control technology, and advocates for sound science and policy during rulemaking implementation. (See Note 6.7. Commitments, Guarantees and Contingencies.)

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

SECURITIES INVESTMENTS

Available-for-Sale Securities. As of September 30, 2021,2022, our available-for-sale securities portfolio consisted primarily of securities held in other postretirement plans to fund employee benefits.

COMMODITY PRICE RISK

Our regulated utility operations incur costs for power and fuel (primarily coal and related transportation) in Minnesota, and power and natural gas purchased for resale in our regulated service territory in Wisconsin. Minnesota Power’s exposure to price risk for these commodities is significantly mitigated by the current ratemaking process and regulatory framework, which allows recovery of fuel costs in excess of those included in base rates or distribution of savings in fuel costs to ratepayers. SWL&P’s exposure to price risk for natural gas is significantly mitigated by the current ratemaking process and regulatory framework, which allows the commodity cost to be passed through to customers. We seek to prudently manage our customers’ exposure to price risk by entering into contracts of various durations and terms for the purchase of power and coal and related transportation costs (Minnesota Power), and natural gas (SWL&P).

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK (Continued)

POWER MARKETING

Minnesota Power’s power marketing activities consist of: (1) purchasing energy in the wholesale market to serve its regulated service territory when energy requirements exceed generation output; and (2) selling excess available energy and purchased power. From time to time, Minnesota Power may have excess energy that is temporarily not required by retail and municipal customers in our regulated service territory. Minnesota Power actively sells any excess energy to the wholesale market to optimize the value of its generating facilities.

We are exposed to credit risk primarily through our power marketing activities. We use credit policies to manage credit risk, which includes utilizing an established credit approval process and monitoring counterparty limits.

INTEREST RATE RISK

We are exposed to risks resulting from changes in interest rates as a result of our issuance of variable rate debt. We manage our interest rate risk by varying the issuance and maturity dates of our fixed rate debt, limiting the amount of variable rate debt, and continually monitoring the effects of market changes in interest rates. We may also enter into derivative financial instruments, such as interest rate swaps, to mitigate interest rate exposure. Interest rates on variable rate long-term debt are reset on a periodic basis reflecting prevailing market conditions. Based on the variable rate debt outstanding as of September 30, 2021,2022, an increase of 100 basis points in interest rates would impact the amount of pre-tax interest expense by $3.4$2.8 million. This amount was determined by considering the impact of a hypothetical 100 basis point increase to the average variable interest rate on the variable rate debt outstanding as of September 30, 2021.2022.


ITEM 4.  CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures. As of September 30, 2021,2022, evaluations were performed, under the supervision and with the participation of management, including our principal executive officer and principal financial officer, on the effectiveness of the design and operation of ALLETE’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934 (Exchange Act)). Based upon those evaluations, our principal executive officer and principal financial officer have concluded that such disclosure controls and procedures are effective to provide assurance that information required to be disclosed in ALLETE’s reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, to allow timely decisions regarding required disclosure.

Changes in Internal Controls. There has been no change in our internal control over financial reporting that occurred during our most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

ITEM 1A.  RISK FACTORS

Our 20202021 Form 10-K includes a detailed discussion of our risk factors. The information presented below updates, and should be read in conjunction with, the risk factors disclosed in Part I, Item 1A. Risk Factors of our 20202021 Form 10-K.

ALLETE Clean Energy / Corporate and Other Risks

The price of electricity may be volatile, which may impact results of operations at ALLETE Clean Energy wind energy facilities under certain contracts with customercommercial and industrial (C&I) customers.

Unusual, adverse weather conditions or other natural events and different settlement prices between hub and node can cause volatility in market prices for electricity and adversely affect our financial position, results of operations and cash flows. ALLETE Clean Energy’s power sales agreements with its three C&I customers at its Diamond Spring and Caddo wind energy facilityfacilities are contracts for differences where power is delivered to the market, and a fixed price is paid by the customers to ALLETE Clean Energy, and differences between the market price and the fixed price are paid to or received from the customers. One of these power sales agreementsCertain contracts also settle with the market at the hub price whereas ALLETE Clean Energy settles with the customer at the node price which can vary significantly based on day-ahead electricity prices, while deliveries to the market are settled based on real-time electricity prices. Thismultiple factors. These settlement provisionprovisions can result in an adverse impact to the Companyon our financial position, results of operations and cash flows when market prices are extremely volatile as happenedvolatile.

Our results of operations could be adversely affected by changes in February 2021 duringgovernmental incentives or policies that support renewable energy or changes in taxes, tariffs, duties or other assessments on renewable energy or the equipment necessary to generate and deliver it.

Any reductions or modifications to, or the elimination of, governmental incentives or policies that support renewable energy, or the imposition of additional or increased sourcing of components subject to taxes, tariffs, duties or other assessments on renewable energy or the equipment necessary to generate and deliver it, could result in, among other items, the lack of a satisfactory market for the development or financing of new renewable energy projects and reduced project returns on current or future projects.

The U.S. government currently imposes antidumping and countervailing duties on certain imported photovoltaic (PV) cells and modules from China and Taiwan. Such duties can change over time pursuant to annual reviews conducted by the U.S. Department of Commerce (DOC). In March 2022, the U.S. DOC launched an extreme winter weather eventinvestigation into alleged circumvention of these duties by imports of certain PV cells and modules assembled and completed in Cambodia, Malaysia, Thailand, and Vietnam. In June 2022, the U.S. President declared an emergency with respect to threats to electricity generation capacity and authorized the U.S. Secretary of Commerce to consider permitting the importation of certain PV products from those four countries free of antidumping and countervailing duties for 24 months, or until the emergency has terminated. The U.S. DOC has issued final regulations designed to implement that moratorium in the southwest United States. This winter weather event caused extreme volatility,that it finds circumvention in its ongoing inquiries. We cannot predict what further actions the U.S. DOC will take with large differencesrespect to these circumvention inquiries. Our operating results could be adversely impacted if the U.S. DOC makes circumvention determinations that result in duties assessed on future purchases made by our businesses after the day-ahead and real-time market prices; the settlement provision resulted in an approximately $5 million after-tax negative impact related to the Diamond Spring wind energy facility.moratorium ends.
