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 as of and during the three months ended March 31, 2020, related to the tax equity financing structure for ALLETE Clean Energy’s 106 MW Glen Ullin wind energy facility.

On April 16, 2020, ALLETE Clean Energy commenced operations of South Peak, an 80 MW wind energy facility in Montana, and on April 29, 2020, received approximately $70 million in cash from a third-party investor as part of a tax equity financing for the 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.

New Accounting Pronouncements.

Credit Losses. In 2016, the FASB issued an accounting standard update that requires entities to recognize an allowance for expected credit losses for financial instruments within its scope. Examples of financial instruments within the scope include trade receivables, certain financial guarantees, and held-to-maturity debt securities. The allowance for expected credit losses should be based on historical information, current conditions and reasonable and supportable forecasts. The new standard also revises the other-than-temporary impairment model for available-for-sale debt securities. The new guidance became effective January 1, 2020, and was adopted by the Company in the first quarter of 2020. Adoption of this standard did not have a material impact on our Consolidated Financial Statements.

NOTE 2. REGULATORY MATTERS

Regulatory matters are summarized in Note 4. Regulatory Matters to the Consolidated Financial Statements in our 2019 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 $9.6 million for the three months ended March 31, 2020 ($7.4 million for three months ended March 31, 2019).

2020 Minnesota General Rate Case. On November 1, 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 seeks 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 generate approximately $66 million in additional revenue. In orders dated December 23, 2019, the MPUC accepted the filing as complete and authorized an annual interim rate increase of $36.1 million that began January 1, 2020. We cannot predict the level of final rates that may be authorized by the MPUC.

On April 23, 2020, Minnesota Power filed a request with the MPUC that proposes a resolution for Minnesota Power’s 2020 general rate case. Key components of our proposal include removing the current 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 of approximately $12 million ($9 million as of March 31, 2020,); increasing ongoing customer rates 4.1 percent compared to the 5.8 percent increase reflected in current interim rates; and a provision that Minnesota Power would not file another rate case until at least March 1, 2021, unless certain events occur. Minnesota Power would withdraw its general rate case upon approval of this filing and proposed resolution by the MPUC. At a hearing on April 30, 2020, the MPUC approved lowering current interim rates to 4.1 percent effective May 1, 2020, as requested by Minnesota Power in this filing. A final decision on Minnesota Power’s full proposal in this filing is expected in June 2020. At this time, we are unable to predict whether the MPUC will ultimately approve this filing and proposed resolution, and thus, as of March 31, 2020, we have not recorded reserves for interim rates.

NOTE 2. REGULATORY MATTERS (Continued)

Electric Rates (Continued)

Transmission Cost Recovery Rider. Minnesota Power has an approved cost recovery rider in place for certain transmission investments and expenditures. In a 2016 order, the MPUC approved Minnesota Power’s updated customer billing rates allowing Minnesota Power to charge retail customers on a current basis for the costs of constructing certain transmission facilities plus a return on the capital invested. On July 9, 2019, Minnesota Power filed a petition seeking MPUC approval to update the customer billing factor to include investments made for the GNTL. (See Note 6. Commitments, Guarantees and Contingencies.)

Renewable Cost Recovery Rider. 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. Current customer billing rates for the renewable cost recovery rider were approved by the MPUC in a November 2018 order. On August 15, 2019, Minnesota Power filed a petition seeking MPUC approval to update the customer billing factor.

Fuel Adjustment Clause Reform. In a 2017 order, the MPUC adopted a program to implement certain procedural reforms to Minnesota utilities’ automatic fuel adjustment clause (FAC) for fuel and purchased power. With this order, the method of accounting for all Minnesota electric utilities changed to a monthly budgeted, forward-looking FAC with annual prudence review and true-up to actual allowed costs. On May 1, 2019, Minnesota Power filed its fuel adjustment forecast for 2020, which was accepted by the MPUC in an order dated November 14, 2019, for purposes of setting fuel adjustment clause rates for 2020, subject to a true-up filing in 2021.

COVID-19 Related Costs. In an order dated March 24, 2020, the PSCW authorized public utilities, which includes SWL&P, to defer expenditures incurred by the utility resulting from its compliance with state government or regulator orders, and as otherwise required to ensure the provision of safe, reliable and affordable access to utility services 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 COVID-19, and to defer and record such costs as a regulatory asset, subject to recovery in a future proceeding. 

Integrated Resource Plan. In a 2016 order, the MPUC approved Minnesota Power’s 2015 IRP with modifications. The order accepted Minnesota Power’s plans for the economic idling of Taconite Harbor Units 1 and 2 and the ceasing of coal-fired operations at Taconite Harbor in 2020, directed Minnesota Power to retire Boswell Units 1 and 2 no later than 2022, required an analysis of generation and demand response alternatives to be filed with a natural gas resource proposal, and required Minnesota Power to conduct requests for proposal for additional wind, solar and demand response resource additions. Minnesota Power retired Boswell Units 1 and 2 in the fourth quarter of 2018. Minnesota Power’s next IRP filing is due October 1, 2020.

Nemadji Trail Energy Center. In 2017, Minnesota Power submitted a resource package to the MPUC which included requesting approval of a 250 MW natural gas capacity dedication agreement. The natural gas capacity dedication agreement was subject to MPUC approval of the construction of NTEC, a 525 MW to 550 MW combined-cycle natural gas‑fired generating facility which will be jointly owned by Dairyland Power Cooperative and a subsidiary of ALLETE. Minnesota Power would purchase approximately 50 percent of the facility's output starting in 2025. In an order dated January 24, 2019, the MPUC approved Minnesota Power’s request for approval of the NTEC natural gas capacity dedication agreement. Separately, the MPUC required a baseload retirement evaluation in Minnesota Power’s next IRP filing analyzing its existing fleet, including potential early retirement scenarios of Boswell Units 3 and 4, as well as a securitization plan. On December 23, 2019, the Minnesota Court of Appeals reversed and remanded the MPUC’s decision to approve certain affiliated-interest agreements. The MPUC was ordered to determine whether NTEC may have the potential for significant environmental effects and, if so, to prepare an environmental assessment worksheet before reassessing the agreements. On January 22, 2020, Minnesota Power filed a petition for further review with the Minnesota Supreme Court requesting that it review and overturn the Minnesota Court of Appeals decision, which petition was accepted for review by the Minnesota Supreme Court on March 18, 2020. On January 8, 2019, an application for a certificate of public convenience and necessity for NTEC was submitted to the PSCW, which was approved by the PSCW at a hearing on January 16, 2020. 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 ALLETE’s portion is expected to be approximately $350 million. ALLETE’s portion of NTEC project costs incurred through March 31, 2020, is approximately $13 million.

MISO Return on Equity Complaint. MISO transmission owners, including ALLETE and ATC, have an authorized return on equity of 9.88 percent, or 10.38 percent including an incentive adder for participation in a regional transmission organization, based on a November 2019 FERC order. In this order, the FERC reduced the base return on equity for regional transmission organizations as recommended by an administrative law judge with refunds ordered for prior periods, which are immaterial to ALLETE. Multiple parties to the complaint have filed requests for rehearing of the FERC order.

NOTE 2. REGULATORY MATTERS (Continued)

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. 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. In the three months ended March 31, 2020, we invested $0.4 million in ATC, and on April 30, 2020, we invested an additional $0.8 million. We expect to make additional investments of $1.6 million in 2020.

ATC’s authorized return on equity is 9.88 percent, or 10.38 percent including an incentive adder for participation in a regional transmission organization based on a November 2019 FERC order. (See Note 2. Regulatory Matters.)

Investment in Nobles 2. Our wholly-owned subsidiary, ALLETE South Wind, owns 49 percent of Nobles 2, the entity that will own and operate a 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. As of March 31, 2020, our equity investment in Nobles 2 was $83.4 million ($56.0 million at December 31, 2019). In the three months ended March 31, 2020, we invested $27.4 million in Nobles 2, and in April 2020 we invested an additional $21.7 million. We expect to make approximately $65 million in additional investments in 2020.

NOTE 4. 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 7. Fair Value to the Consolidated Financial Statements in our 2019 Form 10-K.

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 March 31, 2020, and December 31, 2019. 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.

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis. Non-financial assets such as equity method investments, land inventory, and property, plant and equipment are measured at fair value when there is an indicator of impairment and recorded at fair value only when an impairment is recognized. For the three months ended March 31, 2020, and the year ended December 31, 2019, there were no indicators of impairment for these non-financial assets.

We had $66.3 million outstanding in standby letters of credit and $0.2 million in outstanding draws under our lines of credit as of March 31, 2020 ($62.0 million in standby letters of credit and no outstanding draws as of December 31, 2019).

On January 10, 2020, ALLETE entered into a $200 million unsecured term loan agreement (Term Loan) of which we have borrowed $110 million as of March 31, 2020. The Term Loan provides for the ability to borrow up to an additional $90 million, is due on February 10, 2021, and may be repaid at any time. Interest is payable monthly at a rate per annum equal to LIBOR plus 0.55 percent. Proceeds from the Term Loan will be used for construction-related expenditures.

On March 26, 2020, ALLETE agreed to sell first mortgage bonds (Bonds) to certain institutional buyers in the private placement market, which will be issued on or before August 3, 2020, in two series as follows:

Maturity Date	Principal Amount	Interest Rate
August 1, 2030	$46 Million	2.50%
August 1, 2050	$94 Million	3.30%

ALLETE will have the option to prepay all or a portion of the Bonds at its discretion, subject to a make-whole provision. The Bonds will be subject to additional terms and conditions which are customary for these types of transactions. ALLETE plans to use the proceeds from the sale of the Bonds to fund utility capital investment and for general corporate purposes. The Bonds will be 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.

On April 8, 2020, ALLETE entered into a $115 million unsecured term loan agreement (Term Loan) and borrowed $95 million upon execution. The Term Loan provides for an additional draw of $20 million on or after July 1, 2020. The Term Loan is due on April 7, 2021, and may be repaid at any time. Interest is payable monthly at a rate per annum equal to LIBOR plus 1.7 percent with a LIBOR floor of 0.75 percent. Proceeds from the Term Loan will be used for general corporate purposes.

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 March 31, 2020, our ratio was approximately 0.43 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 March 31, 2020, ALLETE was in compliance with its financial covenants.

NOTE 6. 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 9. Commitments, Guarantees and Contingencies to the Consolidated Financial Statements in our 2019 Form 10-K, with additional disclosure provided in the following paragraphs.

Square Butte PPA. As of March 31, 2020, Square Butte had total debt outstanding of $276.2 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 three months ended March 31, 2020, was $20.1 million ($20.5 million for the same period in 2019). 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 $1.9 million ($2.1 million for the same period in 2019). 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, it sold to Minnkota Power approximately 28 percent in 2020 and in 2019.

Minnesota Power Short-term PSAs. Minnesota Power has entered into various short-term PSAs to sell 300 MW of energy in 2020 and 2021. These PSAs were entered into to proactively mitigate the uncertainty of customers’ energy needs and potential load loss due to the COVID-19 pandemic. Additional transactions, purchases or sales, could be entered into as the extent and duration of the COVID-19 pandemic becomes known.

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. Minnesota Power also has coal transportation agreements in place for the delivery of a significant portion of its coal requirements through December 2021. The costs of fuel and related transportation costs for Minnesota Power’s generation are recoverable from Minnesota Power’s utility customers through the fuel adjustment clause.

Transmission. We continue to make investments in transmission opportunities that strengthen or enhance the transmission grid or take advantage of our geographical location between sources of renewable energy and end users. These include the GNTL, investments to enhance our own transmission facilities, investments in other transmission assets (individually or 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 is required. As a result, Minnesota Power is constructing 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 a 2016 order, the MPUC approved the route permit for the GNTL, and in 2016, the U.S. Department of Energy issued a presidential permit to cross the U.S.-Canadian border, which was the final major regulatory approval needed before construction in the U.S. could begin. Construction activities commenced in the first quarter of 2017, and Minnesota Power expects the GNTL to be in-service by mid-2020. The total project cost in the U.S., including substation work, is estimated to be approximately $700 million, of which Minnesota Power’s portion is expected to be approximately $325 million; the difference will be recovered from a subsidiary of Manitoba Hydro as non-shareholder contributions to capital. Total project costs of $647.7 million have been incurred through March 31, 2020, of which $344.6 million has been recovered from a subsidiary of Manitoba Hydro.

In June 2019, Manitoba Hydro announced the Canadian federal government’s approval of the MMTP project and in August 2019, the Canadian National Energy Board granted final pre-construction approvals. Construction on the MMTP commenced in the third quarter of 2019. On April 16, 2020, Manitoba Hydro announced that construction of the MMTP was complete and that testing and commissioning of the line, communications equipment and substation will take place to meet the anticipated in-service deadline of June 1, 2020. The MMTP is still subject to legal challenges which Minnesota Power is actively monitoring.

NOTE 6. COMMITMENTS, GUARANTEES AND CONTINGENCIES (Continued)

Transmission (Continued)

Construction of Manitoba Hydro’s Keeyask hydroelectric generation facility, which will provide the power to be sold under PPAs with Minnesota Power and transmitted on the MMTP and the GNTL, commenced in 2014 and is anticipated to be completely in-service by early 2021.

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 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 NO_X 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 NO_x and SO₂ allowances issued and pending issuance, we currently expect generation levels and emission rates will result in continued compliance with the CSAPR.

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. None of the compliance costs for proposed or current NAAQS revisions are expected to be material.

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 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. On June 19, 2019, the EPA finalized several separate rulemakings regarding regulating carbon emissions from electric utility generating units.

The EPA repealed the Clean Power Plan (CPP), following a determination by the EPA that the CPP exceeded the EPA’s statutory authority under the Clean Air Act (CAA). The primary reason for this was that the CPP attempted to regulate electric generating unit’s carbon emissions through measures outside of the affected unit’s direct control. The CPP was first announced as a proposed rule under Section 111(d) of the Clean Air Act for existing power plants entitled “Carbon Pollution Emission Guidelines for Existing Stationary Sources: Electric Generating Units”.

With the repeal of the CPP, the Affordable Clean Energy Rule was finalized. The rule establishes emissions guidelines for states to use when developing plans to limit carbon dioxide at coal-fired power plants. The rule identifies heat rate improvements made at individual units as the best system of emission reduction. Affected facilities for Minnesota Power include Boswell Units 3 and 4. Based on our initial review of the rule, many of the candidate heat rate improvements are already installed on Boswell Units 3 and 4 and the currently economically idled Taconite Harbor 1 and 2.

Additionally, the EPA finalized new regulations for the state implementation of the Affordable Clean Energy Rule and any future emission guidelines issued under CAA Section 111(d). States will have three years to submit State Implementation Plans (SIPs), and the EPA has 12 months to review and approve those plans. Since the Affordable Clean Energy Rule allows states considerable flexibility in how to best implement its requirements, Minnesota Power plans to work closely with the MPCA and the Minnesota Department of Commerce, who are currently co-reviewing the rule as the state develops its SIP. If a state does not submit a SIP or submits a SIP that is unacceptable to the EPA, the EPA will develop a Federal Implementation Plan. The MPCA currently plans to develop a SIP for the Affordable Clean Energy Rule.

Minnesota had already initiated several measures consistent with those called for under the now repealed CPP and finalized 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. (See Note 2. Regulatory Matters.) We are unable to predict the GHG emission compliance costs we might incur as a result of the Affordable Clean Energy Rule and the resulting SIP; however, the costs could be material. Minnesota Power would seek recovery of additional costs through a rate proceeding.

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 reconsiders the bottom ash transport water 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 November 22, 2019, the EPA published a draft rulemaking that proposes to allow re-use of bottom ash transport water in FGD scrubber systems with minor discharges related to maintaining system water balance. The proposed rulemaking would also allow future discharge of FGD wastewater discharge provided it meets new BACT standards. A final rulemaking is anticipated in mid to late 2020.

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 if additional water treatment measures are implemented. Under the current ELG rule, bottom ash transport water discharge to surface waters must cease no later than December 31, 2023. Bottom ash contact water will either need to be re-used in a closed-loop process, routed to a FGD scrubber, or the bottom ash handling system will need to be converted to a dry process. The ELG rule provision regarding these two waste-streams are being reconsidered and may change prior to November 1, 2020. Efforts have been underway at Boswell to reduce the amount of water discharged and evaluate potential re-use options in its plant processes. The EPA’s additional reconsideration of legacy wastewater discharge requirements have the potential to reduce time lines for dewatering Boswell’s existing bottom ash pond. The timing of a draft rule addressing legacy wastewater and leachate is currently unknown.

At this time, we cannot estimate what compliance costs we might incur related to these or other potential future water discharge regulations; however, the costs could be material, including costs associated with retrofits for bottom ash handling, pond dewatering, pond closure, and wastewater treatment and re-use. 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 stores or disposes coal ash at four of its electric generating facilities by the following methods: 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 occur 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 and in March 2018, published the first phase of the proposed rule revisions in the Federal Register. In July 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 August 2018, a U.S. District Court for the District of Columbia decision vacated specific provisions of the CCR rule. The court decision changed the status of three existing impoundments at Boswell that must now be considered unlined. The EPA proposed additional rule revisions in August and December 2019 to address outstanding issues from litigation and closure timelines for unlined impoundments, respectively. These rules are anticipated to be finalized in 2020 and could impact the timing of closure activities for Boswell’s three impoundments. Additionally, the EPA recently released a proposed Part B rulemaking that addresses options for beneficial reuse of CCR materials, alternative liner demonstrations, and other CCR regulatory revisions. Compliance costs at Boswell due to the court decision are unknown at this time. Minnesota Power would seek recovery of additional costs through a rate proceeding.

Other Environmental Matters

Manufactured Gas Plant Site. We are reviewing and addressing environmental conditions at a former manufactured gas plant site located in Superior, Wisconsin. SWL&P has been working with the Wisconsin Department of Natural Resources (WDNR) in determining the extent of contamination at the site and surrounding properties. In December 2017, the WDNR authorized SWL&P to transition from site investigation into the remedial design process. As of March 31, 2020, we have recorded a liability of approximately $7 million for remediation costs at this site (approximately $7 million as of December 31, 2019). SWL&P has also recorded an associated regulatory asset as we expect recovery of these remediation costs to be allowed by the PSCW. Remediation costs are expected to be incurred through 2023.

Other Matters.

ALLETE Clean Energy. ALLETE Clean Energy’s wind energy facilities have PSAs in place for their entire output and expire in various years between 2022 and 2039. As of March 31, 2020, ALLETE Clean Energy has $59.6 million outstanding in standby letters of credit, the majority of which are held as security under these PSAs and PSAs for wind energy facilities under development.

BNI Energy. As of March 31, 2020, BNI Energy had surety bonds outstanding of $67.7 million related to the reclamation liability for closing costs associated with its mine and mine facilities. Although its coal supply agreements obligate the customers to provide for the closing costs, additional assurance is required by federal and state regulations. BNI Energy’s total reclamation liability is currently estimated at $67.3 million. BNI Energy does not believe it is likely that any of these outstanding surety bonds will be drawn upon.

ALLETE Properties. As of March 31, 2020, ALLETE Properties had surety bonds outstanding and letters of credit to governmental entities totaling $4.1 million primarily related to development and maintenance obligations for various projects. The estimated cost of the remaining development work is $2.0 million. ALLETE Properties does not believe it is likely that any of these outstanding surety bonds or letters of credit will be drawn upon.

Community Development District Obligations. As of March 31, 2020, we owned 53 percent of the assessable land in the Town Center District (53 percent as of December 31, 2019). As of March 31, 2020, ownership levels, our annual assessments related to capital improvement and special assessment bonds for the ALLETE Properties project within the district is approximately $1.9 million. As we sell property at this project, the obligation to pay special assessments will pass to the new landowners. In accordance with accounting guidance, these bonds are not reflected as debt on our Consolidated Balance Sheet.

Legal Proceedings.

We are involved in litigation arising in the normal course of business. Also in the normal course of business, we are involved in tax, regulatory and other governmental audits, inspections, investigations and other proceedings that involve state and federal taxes, safety, and compliance with regulations, rate base and cost of service issues, among other things. We do not expect the outcome of these matters to have a material effect on our financial position, results of operations or cash flows.

(a) For each of the three months ended March 31, 2020, and 2019, the federal and state current tax expense was minimal due to NOLs which resulted from the bonus depreciation provisions of the Protecting Americans from Tax Hikes Act of 2015, the Tax Increase Prevention Act of 2014 and the American Taxpayer Relief Act of 2012. Federal and state NOLs are being carried forward to offset current and future taxable income.

(b) For each of the three months ended March 31, 2020, and 2019, the federal income tax benefit is primarily due to production tax credits.

(c) For the three months ended March 31, 2019, the state income tax expense is primarily related to the sale of U.S. Water Services.

The Company's tax provision for interim periods is determined using an estimate of its annual effective tax rate, adjusted for discrete items arising in that quarter. In each quarter, the Company updates its estimate of the annual effective tax rate and if the estimated annual effective tax rate changes, the Company would make a cumulative adjustment in that quarter.

In addition to historical information, the following discussion and other parts of this Form 10-Q contain forward-looking information that involves risks and uncertainties. Readers are cautioned that forward-looking statements should be read in conjunction with our disclosures in this Form 10-Q, including Part II, Item 1A Risk Factors, and our 2019 Form 10-K under the headings: “Forward-Looking Statements” located on page 6 and “Risk Factors” located in Part I, Item 1A, beginning on page 21 of our 2019 Form 10-K. The risks and uncertainties described in this Form 10-Q and our 2019 Form 10-K are not the only risks facing our Company. Additional risks and uncertainties that we are not presently aware of, or that we currently consider immaterial, may also affect our business operations. Our business, financial condition or results of operations could suffer if the risks are realized.

Our financial position, results of operations and cash flows were not materially impacted during the three months ended March 31, 2020, by the ongoing COVID-19 pandemic; however, the trends and results for the first three months of 2020 may not be indicative of results that may be expected for the year ended December 31, 2020 due to uncertainty regarding the extent and duration of the COVID-19 pandemic. This pandemic has resulted in widespread impacts on the global economy and on our employees, customers, contractors, and suppliers. There is considerable uncertainty regarding the extent to which COVID-19 will spread and the extent and duration of measures to try to contain the virus, such as travel bans and restrictions, quarantines, shelter-in-place orders (including those in effect in areas our businesses operate), and business and government shutdowns. Additional disclosures in this Form 10-Q regarding the impacts of the ongoing COVID-19 pandemic are located in Outlook – Regulated Operations – Industrial Customers and Prospective Additional Load, Liquidity and Capital Resources – Liquidity Position and Part II, Item 1A. Risk Factors.

Regulated Operations includes our regulated utilities, Minnesota Power and SWL&P, as well as our investment in ATC, a Wisconsin-based regulated utility that owns and maintains electric transmission assets in portions of Wisconsin, Michigan, Minnesota and Illinois. Minnesota Power provides regulated utility electric service in northeastern Minnesota to approximately 145,000 retail customers. Minnesota Power also has 15 non-affiliated municipal customers in Minnesota. SWL&P is a Wisconsin utility and a wholesale customer of Minnesota Power. SWL&P provides regulated utility electric, natural gas and water service in northwestern Wisconsin to approximately 15,000 electric customers, 13,000 natural gas customers and 10,000 water customers. Our regulated utility operations include retail and wholesale activities under the jurisdiction of state and federal regulatory authorities. (See Note 2. Regulatory Matters.)

ALLETE Clean Energy focuses on developing, acquiring, and operating clean and renewable energy projects.

CONDITION AND RESULTS OF OPERATIONS (Continued)

ALLETE is incorporated under the laws of Minnesota. Our corporate headquarters are in Duluth, Minnesota. Statistical information is presented as of March 31, 2020, unless otherwise indicated. All subsidiaries are wholly-owned unless otherwise specifically indicated. References in this report to “we,” “us” and “our” are to ALLETE and its subsidiaries, collectively.

Financial Overview

The following net income discussion summarizes a comparison of the three months ended March 31, 2020, to the three months ended March 31, 2019. The trends and results for the first three months of 2020 may not be indicative of full year results for 2020 due to uncertainty regarding the extent and duration of the COVID-19 pandemic. (See Overview.)

Net income attributable to ALLETE for the three months ended March 31, 2020, was $66.3 million, or $1.28 per diluted share, compared to $70.5 million, or $1.37 per diluted share, for the same period in 2019. Net income in 2019 included a gain on the sale of U.S. Water Services of $9.9 million after-tax, or $0.19 per share, and U.S. Water Services results of operations amounted to a loss of $1.1 million after-tax, or $0.02 per share, in the first quarter. The full year gain on sale of U.S. Water Services in 2019 was $13.2 million after-tax, or $0.26 per share.

Regulated Operations net income attributable to ALLETE was $57.5 million for the three months ended March 31, 2020, compared to $51.5 million for the same period in 2019. Net income at Minnesota Power was higher than 2019 primarily due to the implementation of interim rates on January 1, 2020, increased cost recovery rider revenue, the timing of fuel adjustment clause recoveries in 2019 with the adoption of a new fuel adjustment clause methodology for Minnesota utilities beginning in 2020 (see Note 2. Regulatory Matters), and the timing of income taxes. These increases were partially offset by higher expenses, and lower kWh sales to residential, commercial and municipal customers in 2020. Net income at SWL&P was lower than 2019 primarily due to fewer gas and kWh sales to commercial and residential customers resulting from warmer weather in 2020 compared to 2019. Our after-tax equity earnings in ATC were similar to 2019.

ALLETE Clean Energy net income attributable to ALLETE was $11.7 million for the three months ended March 31, 2020, compared to $5.8 million for the same period in 2019. Net income in 2020 included $2.3 million of additional production tax credits generated compared to 2019, higher revenue resulting from higher wind resources and availability, and earnings from the Glen Ullin wind energy facility which commenced operations in December 2019. Net income in 2020 also included additional income tax benefit recorded in 2020 as GAAP requires the recognition of income taxes at the estimated annual effective tax rate. These increases were partially offset by higher depreciation expense.

U.S. Water Services net loss attributable to ALLETE was $1.1 million for three months ended March 31, 2019. ALLETE completed the sale of U.S. Water Services in the first quarter of 2019.

Corporate and Other net loss attributable to ALLETE was $2.9 million for the three months ended March 31, 2020, compared to net income of $14.3 million for the same period in 2019. Net income in 2019 included a gain on the sale of U.S. Water Services of $9.9 million after-tax. Net income in 2020 included lower earnings from marketable equity securities held in benefit trusts. Net income in 2020 also included additional income tax expense recorded in 2020 as GAAP requires the recognition of income taxes at the estimated annual effective tax rate.

Operating Revenue – Utility decreased $16.9 million from 2019 primarily due to lower fuel adjustment clause recoveries, revenue from kWh sales and conservation improvement program recoveries, partially offset by the implementation of interim rates on January 1, 2020, and increased cost recovery rider revenue.

Fuel adjustment clause revenue decreased $12.2 million due to lower fuel and purchased power costs attributable to retail and municipal customers, partially offset by the timing of fuel adjustment clause recoveries in 2019. Beginning in 2020, Minnesota utilities adopted a new fuel adjustment clause methodology. (See Note 2. Regulatory Matters.)

Revenue from kWh sales decreased $9.0 million from 2019 reflecting lower sales to residential, commercial and municipal customers. Sales to residential and commercial customers decreased from 2019 primarily due to warmer weather in 2020. Sales to municipal customers decreased from 2019 as a result of the expiration of a contract with a municipal customer in June 2019. Sales to industrial customers increased primarily due to additional sales to Silver Bay Power, which ceased self-generation in the third quarter of 2019.

Revenue from electric sales to taconite customers accounted for 26 percent of consolidated operating revenue in 2020 (22 percent in 2019). Revenue from electric sales to paper, pulp and secondary wood product customers accounted for 5 percent of consolidated operating revenue in 2020 (5 percent in 2019). Revenue from electric sales to pipelines and other industrial customers accounted for 7 percent of consolidated operating revenue in 2020 (7 percent in 2019).

Conservation improvement program recoveries decreased $2.1 million from 2019 primarily due to a decrease in related expenditures. (See Operating Expenses - Operating and Maintenance.)

Regulated Operations (Continued)

Interim retail rates for Minnesota Power, subject to refund, were approved by the MPUC and became effective January 1, 2020, resulting in revenue of $9.0 million. (See Note 2. Regulatory Matters.)

Cost recovery rider revenue increased $2.3 million primarily due to higher expenditures related to the construction of the GNTL.

Operating Expenses decreased $18.1 million, or 8 percent, from 2019.

Fuel, Purchased Power and Gas – Utility expense decreased $20.8 million, or 19 percent, from 2019 primarily due to lower purchased power prices and fuel costs. Fuel and purchased power expense related to our retail and municipal customers is recovered through the fuel adjustment clause.

Operating and Maintenance expense increased $1.6 million, or 3 percent, from 2019 primarily due to higher contract and professional service expenses and materials purchased for generation facilities, partially offset by a $2.1 million decrease in conservation improvement program expenses.

Depreciation and Amortization expense increased $1.9 million, or 5 percent, from 2019 primarily due to additional property, plant and equipment in service.

Taxes Other than Income Taxes decreased $1.0 million, or 8 percent, from 2019 primarily due to lower property tax expenses resulting from lower estimated taxable market values.

Income Tax Benefit increased $5.2 million from 2019 primarily due to higher production tax credits. We expect our annual effective tax rate in 2020 to be a higher income tax benefit than in 2019 primarily due to lower pre-tax income.

Net Loss Attributable to ALLETE was $1.1 million for the three months ended March 31, 2019. ALLETE completed the sale of U.S. Water Services in the first quarter of 2019.

Corporate and Other

Operating Revenue increased $2.1 million, or 9 percent, from 2019 primarily due to higher revenue at BNI Energy, which operates under cost-plus fixed fee contracts, as a result of higher expenses and more tons sold in 2020 compared to 2019.

Net Loss Attributable to ALLETE was $2.9 million in 2020 compared to net income $14.3 million in 2019. Net income in 2019 included a gain on the sale of U.S. Water Services of $9.9 million after-tax. Net income in 2020 included lower earnings from marketable equity securities held in benefit trusts. Net income in 2020 also included additional income tax expense recorded in 2020 as GAAP requires the recognition of income taxes at the estimated annual effective tax rate. Net income at BNI Energy was $0.7 million in 2020 compared to $1.9 million in 2019, reflecting lower earnings from marketable equity securities held in benefit trusts in 2020. The net loss at ALLETE Properties was $0.5 million in 2020 compared to a net loss of $0.6 million in 2019.

COMPARISON OF THE THREE MONTHS ENDED MARCH 31, 2020 AND 2019 (Continued)

Income Taxes – Consolidated

For the three months ended March 31, 2020, the effective tax rate was a benefit of 27.2 percent (expense of 4.0 percent for the three months ended March 31, 2019). The effective tax rate for 2020 was a higher benefit primarily due to 2019 including a higher tax rate on and higher pre-tax income resulting from the gain on the sale of U.S. Water Services in 2019.

We expect our annual effective tax rate in 2020 to be a higher benefit as compared to 2019 primarily due to higher production tax credits generated by ALLETE Clean Energy in 2020 and lower pre-tax income as 2019 reflected the gain on sale of U.S. Water Services. The effective rate deviated from the combined statutory rate of approximately 28 percent primarily due to production tax credits. (See Note 8. 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, 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 2019 Form 10-K.

OUTLOOK

For additional information see our 2019 Form 10-K.

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 long-term objectives of achieving average annual earnings per share growth of 5 percent to 7 percent, and providing a dividend payout competitive with our industry. Regulated Operations is projected to have average annual earnings growth of 4 percent to 5 percent over the long-term. ALLETE Clean Energy and our Corporate and Other businesses are projected to have average annual earnings growth of at least 15 percent over the long-term. Our annual earnings per share is expected to be negatively impacted in the short-term by the ongoing COVID-19 pandemic and related disruptions; however, the Company expects it will be able to maintain its stated financial objectives for average annual earnings per share growth over the long-term (next five years). (See Part II, Item 1A. Risk Factors.)

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 our 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 2020. Over the next several years, the contribution of ALLETE Clean Energy and our Corporate and Other businesses to net income is expected to increase as ALLETE grows these operations. ALLETE expects its businesses to provide regulated, contracted or recurring revenues, and to support sustained growth in net income and cash flow.

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. (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.

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.

2020 Minnesota General Rate Case. On November 1, 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 seeks 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 generate approximately $66 million in additional revenue. In orders dated December 23, 2019, the MPUC accepted the filing as complete and authorized an annual interim rate increase of $36.1 million that began January 1, 2020. We cannot predict the level of final rates that may be authorized by the MPUC.

On April 23, 2020, Minnesota Power filed a request with the MPUC that proposes a resolution for Minnesota Power’s 2020 general rate case. Key components of our proposal include removing the current 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 of approximately $12 million ($9 million as of March 31, 2020,); increasing ongoing customer rates 4.1 percent compared to the 5.8 percent increase reflected in current interim rates; and a provision that Minnesota Power would not file another rate case until at least March 1, 2021, unless certain events occur. Minnesota Power would withdraw its general rate case upon approval of this filing and proposed resolution by the MPUC. At a hearing on April 30, 2020, the MPUC approved lowering current interim rates to 4.1 percent effective May 1, 2020, as requested by Minnesota Power in this filing. A final decision on Minnesota Power’s full proposal in this filing is expected in June 2020. At this time, we are unable to predict whether the MPUC will ultimately approve this filing and proposed resolution, and thus, as of March 31, 2020, we have not recorded reserves for interim rates.

2018 Wisconsin General Rate Case. SWL&P’s current retail rates are based on a December 2018 PSCW order that allows for a return on equity of 10.4 percent and a 55.0 percent equity ratio. The PSCW has ordered SWL&P to file a general rate case in 2020.

Industrial 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 54 percent of our regulated utility kWh sales in the three months ended March 31, 2020, were made to our industrial customers (51 percent in the three months ended March 31, 2019). These customers and their markets have been impacted by the ongoing COVID-19 pandemic. (See Part II, Item 1A. Risk Factors.)

The ongoing COVID-19 pandemic and related federal and state government responses has led to a disruption of economic activity, and could result in an extended disruption of economic activity. This disruption is expected to result in reduced sales and revenue from industrial customers. The states of Minnesota and Wisconsin issued stay-at-home or shelter-in-place orders in March 2020 that remain in effect, and many non-essential commercial and industrial customers are operating at reduced levels or are temporarily closed or idled. In addition, Cliffs temporarily idled its Northshore Mining operation, Hibbing Taconite temporarily idled production and USS Corporation indefinitely idled its Keetac plant as well as announced a temporary partial shutdown at its Minntac plant, each of which are served by Minnesota Power. (See Northshore Mining, Hibbing Taconite and USS Corporation.) The current disruption of economic activity or an extended disruption of economic activity may lead to additional adverse impacts on our taconite and paper, pulp and secondary wood products, pipeline and other industrial customers’ operations including further reduced production or the temporary idling or indefinite shutdown of other facilities, which would result in lower sales and revenue from these customers.

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. Steel produced from these North American facilities is used primarily in the manufacture of automobiles, appliances, pipe and tube products for the gas and oil industry, and in the construction industry. Historically, less than 10 percent of Minnesota taconite production has been exported outside of North America.

OUTLOOK (Continued)

Industrial Customers and Prospective Additional Load (Continued)

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 three months of 2020 compared to 82 percent in the first three months of 2019; however, the American Iron and Steel Institute also reported that U.S. raw steel production in the last week of April 2020 had decreased to approximately 51 percent of capacity. 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 2019 that U.S. steel consumption in 2020 will increase by approximately one percent compared to 2019; however, this projection was made before the COVID-19 pandemic and the World Steel Association announced in April 2020 that it had decided to postpone its U.S. steel consumption update projection typically released in April each year due to continuing disruption caused by the COVID-19 pandemic.

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.

Northshore Mining. Cliffs is currently constructing a hot briquetted iron production plant in Toledo, Ohio, and had begun shipping direct reduced-grade pellets form Northshore Mining to the Toledo plant in anticipation of the planned start of operations in mid-2020. On March 19, 2020, following guidelines from the office of the Governor of Ohio regarding the COVID-19 pandemic, Cliffs temporarily shut down construction activities at its hot briquetted iron project site. On April 13, 2020, Cliffs announced that based on current market conditions, it will be temporarily idling production at two of its iron ore mining operations, Northshore Mining in Minnesota and Tilden Mine in Michigan. Cliffs idled production at Northshore Mining in April 2020 and plans to restart the facility by August 2020, subject to business conditions. 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 Power.)

Silver Bay Power. In 2016, Minnesota Power and Silver Bay Power entered into a PSA through 2031. Silver Bay Power supplies approximately 90 MW of load to Northshore Mining, an affiliate of Silver Bay Power, which had previously been served predominately through self-generation by Silver Bay Power. Starting 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.

USS Corporation. In April 2020, USS Corporation stated it would indefinitely 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, on May 1, 2020, USS Corporation announced reduced production expected temporarily at its Minntac Plant in Mountain Iron, Minnesota until July 2020. USS Corporation has the capability to produce approximately 20 million tons annually at its Minntac and Keetac plants.

Hibbing Taconite. On April 20, 2020, ArcelorMittal announced that Hibbing Taconite in Hibbing, Minnesota, would idle production until July 2020 due to the COVID-19 pandemic. Hibbing Taconite has the capability to produce approximately 8 million tons annually.

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. In addition, the ongoing COVID-19 pandemic and related federal and state government responses could adversely impact these customers’ operations and result in lower operating levels than expected or the temporary idling or indefinite shutdown of facilities.

Boise. On April 1, 2020, Packaging Corporation of America announced an idling of both paper machines and the sheet-converting operation at its Jackson Mill in Alabama for the months of May and June 2020. As part of that announcement, Packaging Corporation of America also stated that the company's Boise paper mill in International Falls, Minnesota, which is a customer of Minnesota Power, will continue to operate at capacity during this period.

Pipeline and Other Industries.

Husky Energy. In April 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. On September 30, 2019, Husky Energy announced that it had received the required permit approvals to begin reconstruction. On April 20, 2020, Husky Energy announced that rebuild construction at the refinery had been suspended due to the COVID-19 pandemic. Husky Energy did not provide a timeline for when construction would resume. The facility remains at minimal operations.

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.

In 2016, PolyMet submitted applications for water-related permits with the DNR and MPCA, an air quality permit with the MPCA, and a state permit to mine application with the DNR detailing its operational plans for the mine. In June 2018, the U.S. Forest Service and PolyMet closed on a land exchange, which resulted in PolyMet obtaining surface rights to land needed to develop its mining operation. In November 2018, the DNR issued PolyMet’s permit to mine and certain water-related permits. In December 2018, the MPCA issued PolyMet’s final state water and air quality permits. On March 21, 2019, the U.S. Army Corps of Engineers issued PolyMet’s final federal permit. PolyMet was issued all necessary permits to construct and operate its new mining operation; however, on January 13, 2020, the Minnesota Court of Appeals reversed the DNR’s decisions granting PolyMet’s permit to mine and dam-safety permits, and remanded them back to the DNR to hold a contested-case hearing. On February 11, 2020, PolyMet announced it had filed a petition for further review with the Minnesota Supreme Court seeking to overturn the Minnesota Court of Appeals decision, which was accepted for review by the Minnesota Supreme Court on March 25, 2020. 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, a strategic plan for 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 of certain coal-fired generating facilities.

Nemadji Trail Energy Center. In 2017, Minnesota Power submitted a resource package to the MPUC which included requesting approval of a 250 MW natural gas capacity dedication agreement. The natural gas capacity dedication agreement was subject to MPUC approval of the construction of NTEC, a 525 MW to 550 MW combined-cycle natural gas‑fired generating facility which will be jointly owned by Dairyland Power Cooperative and a subsidiary of ALLETE. Minnesota Power would purchase approximately 50 percent of the facility's output starting in 2025. In an order dated January 24, 2019, the MPUC approved Minnesota Power’s request for approval of the NTEC natural gas capacity dedication agreement. Separately, the MPUC required a baseload retirement evaluation in Minnesota Power’s next IRP filing analyzing its existing fleet, including potential early retirement scenarios of Boswell Units 3 and 4, as well as a securitization plan. On December 23, 2019, the Minnesota Court of Appeals reversed and remanded the MPUC’s decision to approve certain affiliated-interest agreements. The MPUC was ordered to determine whether NTEC may have the potential for significant environmental effects and, if so, to prepare an environmental assessment worksheet before reassessing the agreements. On January 22, 2020, Minnesota Power filed a petition for further review with the Minnesota Supreme Court requesting that it review and overturn the Minnesota Court of Appeals decision, which petition was accepted for review by the Minnesota Supreme Court on March 18, 2020. On January 8, 2019, an application for a certificate of public convenience and necessity for NTEC was submitted to the PSCW, which was approved by the PSCW at a hearing on January 16, 2020. 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 ALLETE’s portion is expected to be approximately $350 million. ALLETE’s portion of NTEC project costs incurred through March 31, 2020, is approximately $13 million.

Integrated Resource Plan. In a 2016 order, the MPUC approved Minnesota Power’s 2015 IRP with modifications. The order accepted Minnesota Power’s plans for the economic idling of Taconite Harbor Units 1 and 2 and the ceasing of coal-fired operations at Taconite Harbor in 2020, directed Minnesota Power to retire Boswell Units 1 and 2 no later than 2022, required an analysis of generation and demand response alternatives to be filed with a natural gas resource proposal, and required Minnesota Power to conduct requests for proposal for additional wind, solar and demand response resource additions. Minnesota Power retired Boswell Units 1 and 2 in the fourth quarter of 2018. Minnesota Power’s next IRP filing is due October 1, 2020. (See Note 2. Regulatory Matters.)

Renewable Energy. Minnesota Power’s 2015 IRP includes an update on its plans and progress in meeting the Minnesota renewable energy milestones through 2025. Minnesota Power continues to execute its renewable energy strategy and expects approximately 50 percent of its energy will be supplied by renewable energy sources by 2021.

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 project 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.

Minnesota Power has approval for current cost recovery of investments and expenditures related to compliance with the Minnesota Solar Energy Standard. Currently, there is no approved customer billing rate for solar costs.

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 for the renewable cost recovery rider were provisionally approved by the MPUC in a November 2018 order.

Nobles 2 PPA. In the third quarter of 2018, Minnesota Power and Nobles 2 signed an amended long-term PPA that provides for Minnesota Power to purchase the energy and associated capacity from a 250 MW wind energy facility in southwestern Minnesota for a 20-year period beginning in 2020. 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. This agreement is subject to construction of the wind energy facility. (See Note 3. Equity Investments.)

Manitoba Hydro. Minnesota Power has five long-term PPAs with Manitoba Hydro. The first PPA expires in May 2020. Under this agreement, Minnesota Power is purchasing 50 MW of capacity and the energy associated with that capacity. Both the capacity price and the energy price are adjusted annually by the change in a governmental inflationary index. Under the second 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 on a non-firm basis. The pricing is based on forward market prices. Under this agreement, Minnesota Power will purchase at least one million MWh of energy over the contract term.

The third PPA provides for Minnesota Power to purchase 250 MW of capacity and energy from Manitoba Hydro for 15 years beginning in 2020. The PPA is subject to the construction of the GNTL and MMTP. (See Note 6. Commitments, Guarantees and Contingencies.) The capacity price is adjusted annually until 2020 by the change in a governmental inflationary index. The energy price is based on a formula that includes an annual fixed price component adjusted for the change in a governmental inflationary index and a natural gas index, as well as market prices.

The fourth PPA provides for Minnesota Power to purchase up to 133 MW of energy from Manitoba Hydro for 20 years beginning in 2020. The pricing under this PPA is based on forward market prices. The PPA is subject to the construction of the GNTL and MMTP. (See Note 6. Commitments, Guarantees and Contingencies.)

OUTLOOK (Continued)

EnergyForward (Continued)

The fifth PPA provides for Minnesota Power to purchase 50 MW of capacity from Manitoba Hydro at fixed prices. The PPA began in June 2017 and expires in May 2020.

Transmission. We continue to make investments in transmission opportunities that strengthen or enhance the transmission grid or take advantage of our geographical location between sources of renewable energy and end users. These include the GNTL, investments to enhance our own transmission facilities, investments in other transmission assets (individually or 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 is required. As a result, Minnesota Power is constructing 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 a 2016 order, the MPUC approved the route permit for the GNTL, and in 2016, the U.S. Department of Energy issued a presidential permit to cross the U.S.-Canadian border, which was the final major regulatory approval needed before construction in the U.S. could begin. Construction activities commenced in the first quarter of 2017, and Minnesota Power expects the GNTL to be in-service by mid-2020. The total project cost in the U.S., including substation work, is estimated to be approximately $700 million, of which Minnesota Power’s portion is expected to be approximately $325 million; the difference will be recovered from a subsidiary of Manitoba Hydro as non-shareholder contributions to capital. Total project costs of $647.7 million have been incurred through March 31, 2020, of which $344.6 million has been recovered from a subsidiary of Manitoba Hydro. (See Note 6. Commitments, Guarantees and Contingencies.)

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. As of March 31, 2020, our equity investment in ATC was $142.3 million ($141.6 million as of December 31, 2019). In the three months ended March 31, 2020, we invested $0.4 million in ATC, and on April 30, 2020, we invested an additional $0.8 million. We expect to make additional investments of $1.6 million in 2020.

ATC’s authorized return on equity is 9.88 percent, or 10.38 percent including an incentive adder for participation in a regional transmission organization based on a November 2019 FERC order. In this order, the FERC reduced the base return on equity for regional transmission organizations as recommended by an administrative law judge with refunds ordered for prior periods. Multiple parties to the complaint have filed requests for rehearing of the FERC order.

ATC’s 10-year transmission assessment, which covers the years 2019 through 2028, identifies a need for between $2.9 billion and $3.6 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 six states, approximately 740 MW of nameplate capacity wind energy generation that is contracted under PSAs of various durations. In addition, ALLETE Clean Energy currently has approximately 300 MW of wind energy facilities under construction that it will own and operate with long-term PSAs in place. 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, societal expectations and continual technology advances. State renewable portfolio standards and state or federal regulations to limit GHG emissions 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 and production tax credit requalification of existing facilities.

ALLETE, Inc. First Quarter 2020 Form 10-Q

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 facilities up to 200 MW each, which have long-term PSAs in place for the facilities’ output. At this time, ALLETE Clean Energy expects acquisitions or development of new facilities will be primarily wind or solar facilities in North America. ALLETE Clean Energy is also targeting the development of new facilities up to 200 MW each, which will have long‑term PSAs in place for the output or may be sold upon completion.

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 up to approximately 1,000 MW of production tax credit qualified wind projects through 2022. ALLETE Clean Energy will also invest approximately $80 million through 2020 for production tax credit requalification of up to approximately 500 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 in 2020, $17 million to $22 million annually in 2021 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. (See Part II, Item 1A. Risk Factors.)

In 2018, ALLETE Clean Energy announced that it will build, own and operate the South Peak wind project, an 80 MW wind energy facility in Montana, pursuant to a 15-year PSA with NorthWestern Corporation; construction was completed and tax equity funding was received in the second quarter of 2020.

In May 2019, ALLETE Clean Energy acquired the Diamond Spring wind project in Oklahoma from Apex Clean Energy. ALLETE Clean Energy will build, own and operate the approximately 300 MW wind energy facility. The Diamond Spring wind project is fully contracted to sell wind power under long-term power sales agreements. Construction is expected to be completed in late 2020.

On March 10, 2020, ALLETE Clean Energy acquired the rights to the Caddo wind project in Oklahoma from Apex Clean Energy for approximately $8 million with additional payments required to be made at defined milestones. The full development of this approximately 300 MW wind project would involve the sale of energy to corporate customers under long-term power sales agreements.

ALLETE Clean Energy manages risk by having a diverse portfolio of assets, which includes PSA expiration, technology and geographic diversity. The current operating portfolio of approximately 740 MW is subject to typical variations in seasonal wind with higher wind resources typically available in the winter months. The majority of its planned maintenance leverages this seasonality and is performed during lower wind periods. The current mix of PSA expiration and geographic location for existing facilities is as follows:

Wind Energy Facility	Location	Capacity MW	PSA MW	PSA Expiration
Armenia Mountain	East	101	100%	2024
Chanarambie/Viking	Midwest	98
PSA 1 (a)			12%	2023
PSA 2			88%	2023
Condon	West	50	100%	2022
Glen Ullin	West	106	100%	2039
Lake Benton	Midwest	104	100%	2028
South Peak	West	80	100%	2035
Storm Lake I	Midwest	108	100%	2027
Storm Lake II	Midwest	77
PSA 1			90%	2022
PSA 2			10%	2032
Other	Midwest	17	100%	2028

(a) The PSA expiration assumes the exercise of all renewal options that ALLETE Clean Energy has the sole right to exercise.

Corporate and Other.

BNI Energy. BNI Energy anticipates selling 4.6 million tons of lignite coal in 2020 (4.1 million tons were sold in 2019) and has sold 1.2 million tons for the three months ended March 31, 2020 (1.1 million tons were sold for the three months ended March 31, 2019). BNI Energy operates under cost-plus fixed fee agreements extending through December 31, 2037.

Investment in Nobles 2. Our wholly-owned subsidiary, ALLETE South Wind, owns 49 percent of Nobles 2, the entity that will own and operate a 250 MW wind energy facility in southwestern Minnesota pursuant to a 20-year PPA with Minnesota Power. The wind energy facility will be built in Nobles County, Minnesota, and is expected to be completed in late 2020, with an estimated total project cost of approximately $350 million to $400 million. In the fourth quarter of 2019, we entered into a tax equity funding agreement to finance approximately $116 million of the project costs. We account for our investment in Nobles 2 under the equity method of accounting. As of March 31, 2020, our equity investment in Nobles 2 was $83.4 million ($56.0 million at December 31, 2019). In the three months ended March 31, 2020, we invested $27.4 million in Nobles 2, and in April 2020 we invested an additional $21.7 million. We expect to make approximately $65 million in additional investments in 2020.

ALLETE Properties. ALLETE Properties represents our legacy Florida real estate investment. ALLETE Properties’ major project in Florida is Town Center at Palm Coast, with approximately 800 acres of land available for sale. In addition to this project, ALLETE Properties has approximately 600 acres of other land available for sale. Market conditions can impact land sales and could result in our inability to cover our cost basis and operating expenses including fixed carrying costs such as community development district assessments and property taxes.

Our strategy incorporates the possibility of a bulk sale of the entire ALLETE Properties portfolio. Proceeds from a bulk sale would be strategically deployed to support growth initiatives at our Regulated Operations and ALLETE Clean Energy. ALLETE Properties also continues to pursue sales of individual parcels over time and will continue to maintain key entitlements and infrastructure.

Income Taxes.

ALLETE’s aggregate federal and multi-state statutory tax rate is approximately 28 percent for 2020. ALLETE also has tax credits and other tax adjustments that reduce the combined statutory rate to the effective tax rate. These tax credits and adjustments historically have included items such as investment tax credits, production tax credits, AFUDC‑Equity, depletion, as well as other items. The annual effective rate can also be impacted by such items as changes in income before income taxes, state and federal tax law changes that become effective during the year, business combinations, tax planning initiatives and resolution of prior years’ tax matters. We expect our effective tax rate to be a benefit of approximately 25 percent to 30 percent for 2020 primarily due to federal production tax credits as a result of wind energy generation. We also expect that our effective tax rate will be lower than the combined statutory rate over the next 10 years due to production tax credits attributable to our wind energy generation.

LIQUIDITY AND CAPITAL RESOURCES

Liquidity Position. ALLETE is well-positioned to meet the Company’s liquidity needs; however, the Company is monitoring capital markets and other financing sources in light of the ongoing COVID-19 pandemic. (See Part II, Item 1A. Risk Factors.) A disruption in capital markets could lead to increased borrowing costs or adversely impact our ability to access capital markets or other financing sources. If we are not able to access capital on acceptable terms in sufficient amounts and when needed, or at all, the ability to maintain our businesses or to implement our business plans would be adversely affected.

As of March 31, 2020, we had cash and cash equivalents of $67.0 million, $340.5 million in available consolidated lines of credit, 2.9 million original issue shares of common stock available for issuance through a distribution agreement with Lampert Capital Markets, $90 million available for borrowing under a $200 million term loan entered into in January 2020 and a debt-to-capital ratio of 42 percent. (See Working Capital.)

In addition, ALLETE has agreed to sell $140 million of the Company's first mortgage bonds to be issued on or before August 3, 2020, and on April 8, 2020, ALLETE entered into a $115 million term loan agreement with $95 million borrowed upon execution. (See Note 5. Short-Term and Long-Term Debt.) On April 29, 2020, we received approximately $70 million in cash from a third-party investor as part of a tax equity financing for ALLETE Clean Energy’s South Peak wind energy facility. The Company also has approximately $116 million in commitments from tax equity partners for our investment in Nobles 2, and the Company is actively seeking tax equity funding for ALLETE Clean Energy’s Diamond Spring wind project.

		$4,104.3	100		$3,958.2	100

Cash Flows. Selected information from the Consolidated Statement of Cash Flows is as follows:

For the Three Months Ended March 31,	2020			2019
Millions
Cash, Cash Equivalents and Restricted Cash at Beginning of Period		$92.5			$79.0
Cash Flows from (used for)
Operating Activities	88.8			79.1
Investing Activities	(182.5		)	185.1
Financing Activities	80.1			22.0
Change in Cash, Cash Equivalents and Restricted Cash	(13.6		)	286.2
Cash, Cash Equivalents and Restricted Cash at End of Period		$78.9			$365.2

Operating Activities. Cash from operating activities was slightly higher in 2020 compared to 2019 as cash from operating activities in 2019 included higher non-cash earnings resulting from the gain on sale of U.S. Water Services, the refund of Minnesota Power’s provision for tax reform, and the impact of U.S. Water Services prior to its sale. Cash from operating activities in 2020 reflected lower collections of accounts receivable due to timing and lower cash collected from current cost recovery riders.

Investing Activities. Cash used for investing activities was higher in 2020 compared to 2019. Cash from investing activities in 2019 included proceeds received from the sale of U.S. Water Services. Cash used for investing activities in 2020 included higher additions to property, plant and equipment and additional payments for equity method investments compared to 2019.

Financing Activities. Cash from financing activities was higher in 2020 compared to 2019 primarily due to lower repayments of long-term debt in 2020.

Working Capital. Additional working capital, if and when needed, generally is provided by consolidated bank lines of credit and the issuance of securities, including long-term debt, common stock and commercial paper. As of March 31, 2020, we had consolidated bank lines of credit aggregating $407.0 million ($407.0 million as of December 31, 2019), the majority of which expire in January 2024. We had $66.3 million outstanding in standby letters of credit and $0.2 million outstanding draws under our lines of credit as of March 31, 2020 ($62.0 million in standby letters of credit and no outstanding draws as of December 31, 2019). In addition, as of March 31, 2020, we had 3.6 million original issue shares of our common stock available for issuance through Invest Direct, our direct stock purchase and dividend reinvestment plan, and 2.9 million original issue shares of common stock available for issuance through a distribution agreement with Lampert Capital Markets. The amount and timing of future sales of our securities will depend upon market conditions and our specific needs. In July 2019, we filed Registration Statement No. 333-232905, pursuant to which the remaining shares will continue to be offered for sale, from time to time.

Securities. During the three months ended March 31, 2020, we issued 0.1 million shares of common stock through Invest Direct, the Employee Stock Purchase Plan, and the Retirement Savings and Stock Ownership Plan, resulting in net proceeds of $3.3 million (0.1 million shares were issued for the three months ended March 31, 2019, resulting in net proceeds of $0.8 million). These shares of common stock were registered under Registration Statement Nos. 333-231030, 333-211075, 333-183051 and 333-162890.

Financial Covenants. See Note 5. Short-Term and Long-Term Debt for information regarding our financial covenants.

Pension and Other Postretirement Benefit Plans. Management considers various factors when making funding decisions, such as regulatory requirements, actuarially determined minimum contribution requirements and contributions required to avoid benefit restrictions for the defined benefit pension plans.

LIQUIDITY AND CAPITAL RESOURCES (Continued)

Off-Balance Sheet Arrangements. Off-balance sheet arrangements are summarized in our 2019 Form 10-K, with additional disclosure in Note 6. Commitments, Guarantees and Contingencies.

Credit Ratings. Access to reasonably priced capital markets is dependent in part on credit and ratings. Our securities have been rated by S&P Global Ratings and by Moody’s. Rating agencies use both quantitative and qualitative measures in determining a company’s credit rating. These measures include business risk, liquidity risk, competitive position, capital mix, financial condition, predictability of cash flows, management strength and future direction. Some of the quantitative measures can be analyzed through a few key financial ratios, while the qualitative ones are more subjective. Our current credit ratings are listed in the following table:

Credit Ratings	S&P Global Ratings	Moody’s
Issuer Credit Rating	BBB	Baa1
Commercial Paper	A-2	P-2
First Mortgage Bonds	(a)	A2

(a) Not rated by S&P Global Ratings.

On April 22, 2020, S&P Global Ratings downgraded ALLETE’s long-term issuer credit rating to BBB stable from BBB+ outlook negative and affirmed its short-term rating at A-2. S&P Global Ratings noted the impacts of debt coverage ratios going forward along with the lack of a revenue decoupling mechanism at Minnesota Power combined with the large commercial and industrial presence in its service territory as its rationale for the downgrade.

The disclosure of these credit ratings is not a recommendation to buy, sell or hold our securities. Ratings are subject to revision or withdrawal at any time by the assigning rating organization. Each rating should be evaluated independently of any other rating.

Capital Requirements. Our capital expenditures for 2020 are expected to be approximately $535 million; however, the Company is evaluating its planned capital expenditures and may make adjustments to mitigate impacts of the ongoing COVID-19 pandemic, if appropriate. At this time, we do not have an update to the amount of capital expenditures expected in 2020 due to uncertainty regarding the extent and duration of the COVID-19 pandemic. For the three months ended March 31, 2020, capital expenditures totaled $161.8 million ($85.1 million for the three months ended March 31, 2019). The expenditures were primarily made in the Regulated Operations and ALLETE Clean Energy segments.

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. Commitments, Guarantees and Contingencies.)

Employees.

As of March 31, 2020, ALLETE had 1,352 employees, of which 1,328 were full-time.

Minnesota Power and SWL&P have an aggregate of 471 employees who are members of International Brotherhood of Electrical Workers (IBEW) Local 31. The current labor agreements with IBEW Local 31 expire on April 30, 2023, for Minnesota Power and February 1, 2021, for SWL&P.

BNI Energy has 181 employees, of which 135 are subject to a labor agreement with IBEW Local 1593. The current labor agreement with IBEW Local 1593 expires on March 31, 2023.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

SECURITIES INVESTMENTS

Available-for-Sale Securities. As of March 31, 2020, 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).

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 March 31, 2020, an increase of 100 basis points in interest rates would impact the amount of pre-tax interest expense by $2.6 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 March 31, 2020.

ITEM 4.  CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures. As of March 31, 2020, 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.

Such information is incorporated herein by reference.

ITEM 1A.  RISK FACTORS

Our 2019 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 2019 Form 10-K.

We could be materially adversely affected by the ongoing COVID-19 pandemic for which we are unable to predict the ultimate impact as the extent and duration of the COVID-19 pandemic is uncertain.

The ongoing COVID-19 pandemic has resulted in widespread impacts on the global economy and on our employees, customers, contractors, and suppliers. There is considerable uncertainty regarding the extent to which COVID-19 will spread and the extent and duration of measures to try to contain the virus, such as travel bans and restrictions, quarantines, shelter-in-place orders (including those in effect in areas our businesses operate), and business and government shutdowns. We are responding to the COVID-19 pandemic by taking steps to mitigate the potential risks to us posed by its spread and have implemented our company-wide business continuity plans in response to the pandemic. These plans guide our emergency response, business continuity, and the precautionary measures we are taking on behalf of employees and the public. We have taken additional precautions for our employees who work in the field and for employees who continue to work in our facilities, and we have implemented work from home policies where appropriate. We continue to implement physical and cyber-security measures to ensure that our systems remain functional in order to both serve our operational needs with a remote workforce and keep them running to ensure uninterrupted service to our customers.

The ongoing COVID-19 pandemic and related federal and state government responses has led to a disruption of economic activity, and could result in an extended disruption of economic activity. This disruption has resulted and is expected to continue to result in reduced sales and revenue from commercial, municipal and industrial customers as well as an increase in uncollectible accounts from residential and commercial customers. The states of Minnesota and Wisconsin issued stay-at-home or shelter-in-place orders in March 2020 that remain in effect, and many non-essential commercial and industrial customers are operating at reduced levels or are temporarily closed or idled. In addition, as a result of the COVID-19 pandemic, Cliffs temporarily idled its Northshore Mining operation, Hibbing Taconite temporarily idled production and USS Corporation indefinitely idled its Keetac plant as well as announced a temporary partial shutdown at its Minntac plant, each of which are served by Minnesota Power. (See Outlook – Regulated Operations – Industrial Customers and Prospective Additional Load.) The current disruption of economic activity or an extended disruption of economic activity may lead to additional adverse impacts on our taconite mining, paper, pulp and secondary wood products, and pipeline customers’ operations including further reduced production or the temporary idling or indefinite shutdown of other facilities, which would result in lower sales and revenue from these customers. In Minnesota Power’s service territory, we have also voluntarily and as requested by state regulators extended Minnesota’s cold weather rule as well as temporarily suspended disconnections for non-payment and waved late payment charges for residential and small business customers. In SWL&P’s service territory, we have implemented state regulator requested customer service actions to further limit service disconnections and late payment charges for residential, commercial and industrial customers.

ITEM 1A.  RISK FACTORS (Continued)

We could be materially adversely affected by the ongoing COVID-19 pandemic for which we are unable to predict the ultimate impact as the extent and duration of the COVID-19 pandemic is uncertain (Continued)

The Company is monitoring the capital markets and has access to liquidity to enable us to operate our businesses and fund capital projects; however, a disruption in capital markets could lead to increased borrowing costs or adversely impact our ability to access capital markets or other financing sources. If we are not able to access capital on acceptable terms in sufficient amounts and when needed, or at all, the ability to maintain our businesses or to implement our business plans would be adversely affected. In addition, the performance of capital markets impacts the values of the assets that are held in trust to satisfy future obligations under our pension and other postretirement benefit plans. A decline in the market value of these assets would increase the funding requirements under our benefit plans and future costs recognized for the benefit plans if the asset market values do not recover. The Company is also monitoring supply chains for key materials, supplies and services for our operations and large capital projects. We have received notices of force majeure from certain suppliers and the pandemic could result in a disruption to our supply chains which could adversely impact our operations and capital projects; however, there has been limited impact on our supply chains as to the availability of materials, supplies and services to date. In addition, disruptions in our supply chains or a lack of available financing could jeopardize our ability to complete certain capital projects in time to qualify them for production tax credits.

We will continue to monitor developments affecting our workforce, operations and customers, and we will take additional precautions that we determine are necessary in order to mitigate the impacts of the COVID-19 pandemic. Despite our efforts to manage these impacts to the Company, their ultimate impact also depends on factors beyond our control, including the duration and severity of this pandemic as well as governmental and third-party actions taken to contain its spread and mitigate its public health effects. As a result, we cannot predict the ultimate impact of the COVID-19 pandemic and whether it will have a material impact on our liquidity, financial position, results of operations and cash flows.
