NOTE 3—CREDIT LOSSES

Effective January 1, 2020, we adopted FASB ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, using the modified retrospective transition method. This ASU amends the impairment model to utilize an expected loss methodology in place of the incurred loss methodology for financial instruments, including trade receivables. The amendment requires entities to consider a broader range of information to estimate expected credit losses, which may result in earlier recognition of loss. The cumulative effect of adopting this standard was not significant to our financial statements.

Our exposure to credit losses is related to our accounts receivable and unbilled revenue balances, which are generated from the sale of electricity and natural gas by our regulated utility operations. Our regulated utility operations are included in our utility segment. NaN accounts receivable and unbilled revenue balances were reported in the other segment at September 30,March 31, 2021 and December 31, 2020.

We evaluate the collectability of our accounts receivable and unbilled revenue balances considering a combination of factors. For some of our larger customers and also in circumstances where we become aware of a specific customer's inability to meet its financial obligations to us, we record a specific allowance for credit losses against amounts due in order to reduce the net recognized receivable to the amount we reasonably believe will be collected. For all other customers, we use the accounts receivable aging method to calculate an allowance for credit losses. Using this method, we classify accounts receivable into different aging buckets and calculate a reserve percentage for each aging bucket based upon historical loss rates. The calculated reserve percentages are updated on at least an annual basis, in order to ensure recent macroeconomic, political, and regulatory trends are captured in the calculation, to the extent possible. Risks identified that we do not believe are reflected in the calculated reserve percentages, are assessed on a quarterly basis to determine whether further adjustments are required. The incremental reserve included within our allowance for credit losses at September 30, 2020, specific to the economic risks associated with the COVID-19 pandemic, was not significant. We will continue to monitor the economic impacts of COVID-19 and the resulting effects that these impacts may have on the ability of our customers to pay their energy bills.

We monitor our ongoing credit exposure through active review of counterparty accounts receivable balances against contract terms and due dates. Our activities include timely account reconciliation, dispute resolution and payment confirmation. To the extent possible, we work with customers with past due balances to negotiate payment plans, but will disconnect customers for non-payment as allowed by the PSCW, if necessary, and employ collection agencies and legal counsel to pursue recovery of defaulted receivables. For our larger customers, detailed credit review procedures may be performed in advance of any sales being made. We sometimes require letters of credit, parental guarantees, prepayments or other forms of credit assurance from our larger customers to mitigate credit risk. See Note 19,18, Regulatory Environment, for information on certain regulatory actions that were and/or are being taken for the purpose of ensuring that essential utility services are available to our customers during the COVID-19 pandemic.

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

(1)Our exposure to credit losses for certain regulated utility customers is mitigated by a regulatory mechanism we have in place. Specifically, our residential tariffs include a mechanism for cost recovery or refund of uncollectible expense based on the difference between actual uncollectible write-offs and the amounts recovered in rates. As a result, at September 30, 2020, $208.4March 31, 2021, $226.0 million, or 48.1%38.5%, of our net accounts receivable and unbilled revenues balance had regulatory protections in place to mitigate the exposure to credit losses. In addition, we have received specific orders related to the deferral of certain costs (including credit losses) incurred as a result of the COVID-19 pandemic. The additional protections related to our September 30, 2020 accounts receivable and unbilled revenue balances provided by these orders are subject to prudency reviews and are still being assessed. They are not reflected in the percentage in the above table or this note. See Note 19,18, Regulatory Environment, for more information on these orders.

This is a trend we generally see overincrease in accounts receivable balances in arrears was driven by the winter moratorium months, when we are not allowed to disconnect customer servicecontinued economic disruptions caused by the COVID-19 pandemic, including continued high unemployment rates. Also, as a result of non-payment. Inthe Wisconsin the winter moratorium begins on November 1rules, and ends on April 15.

NOTE 5—PROPERTY, PLANT, AND EQUIPMENT

During a significant rain event in May 2020, an underground steam tunnel in downtown Milwaukee flooded and steam vented into our Public Service Building. The damage to the building from the flooding and steam was extensive and will require significant repairs and restorations. As of September 30, 2020,March 31, 2021, we hadhave incurred $16.8$49.3 million of costs related to these repairs and restorations,restorations. We received $20.0 million of insurance proceeds in 2020 to cover a portion of these costs and our balance sheet included$16.8 million was recorded as a receivable from WEC Energy Group for thefuture insurance proceeds it received on our behalf, which are sufficient to cover these costs.recoveries as of March 31, 2021. The remaining $12.5 million of costs were included in other operation and maintenance expense in 2020. We are working closely with our insurance carriers, and we anticipate that any current andthe majority of future capital expenditures required to restore the Public Service Building will largelyeither be covered by insurance.insurance or recovery will be requested from the PSCW. As such, we do not currently expect a significant impact to our future results of operations, and although we may experience differences between periods in the timing of cash flows, we also do not currently expect a significant impact to our long-term cash flows from this event.

NOTE 6—COMMON EQUITY

Various financing arrangements and regulatory requirements impose certain restrictions on our ability to transfer funds to WEC Energy Group in the form of cash dividends, loans, or advances. In addition, Wisconsin law prohibits us from making loans to or guaranteeing obligations of WEC Energy Group or its subsidiaries. See Note 8, Common Equity, in our 20192020 Annual Report on Form 10-K for additional information on these and other restrictions.

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

NOTE 8—LEASES

See Note 12, Leases, in our 2019 Annual Report on Form 10-K for information related to the power plants we lease from We Power. As new capital projects are completed at these plants, our lease payments to We Power increase. In addition to increases in our lease payments to We Power, we also entered into lease agreements associated with our investment in Badger Hollow II in the second quarter of 2020, as discussed below.

We have partnered with an unaffiliated utility to construct Badger Hollow II in Iowa County, Wisconsin. Once constructed, we will own 100 MW of this project. The PSCW approved the acquisition of Badger Hollow II in March 2020 and commercial operation is targeted for December 2022.

Related to our investment in Badger Hollow II, we, along with an unaffiliated utility partner, entered into several land leases in Iowa County, Wisconsin that commenced in the second quarter of 2020. The leases are for a total of approximately 1,500 acres of land. Each lease has an initial construction term that ends upon achieving commercial operation, then automatically extends for 25 years with an option for an additional 25-year extension. We expect the optional extension to be exercised, and, as a result, the land leases are being amortized over the extended term of the leases. The lease payments will be recovered through rates.

Our total obligation under the land related finance leases for Badger Hollow II was $22.9 million at September 30, 2020, and will decrease to 0 over the remaining lives of the leases. Long-term lease liabilities related to our finance leases for Badger Hollow II were included in finance lease obligations on the balance sheets. Our finance lease right of use asset related to Badger Hollow II was $22.7 million as of September 30, 2020, and was included in property, plant, and equipment on our balance sheets.

In accordance with Accounting Standard Codification Subtopic 980-842, Regulated Operations – Leases (Subtopic 980-842), the expense recognition pattern associated with the Badger Hollow II leases resembles that of an operating lease, as amortization of the right of use assets has been modified from what would typically be recorded for a finance lease under Topic 842. The difference between the minimum lease payments and the sum of imputed interest and unadjusted amortization costs calculated under Topic 842 is deferred as a regulatory asset in accordance with Subtopic 980-842 on our balance sheet.

At September 30, 2020, our weighted-average discount rate for the Badger Hollow II finance leases was 3.44%. We used the fully collateralized incremental borrowing rates based upon information available for similarly rated companies in determining the present value of lease payments.

In accordance with the rate order received from the PSCW in December 2019, we are amortizing the unprotected deferred tax benefits over periods ranging from two years to four years, to reduce near-term rate impacts to our customers. In addition, the impact of the protected benefits associated with the Tax Legislation, as discussed in more detail below, and wind production tax creditsPTCs drove a decrease in the effective tax rate, which was partially offset by state income taxes.

The effective tax rates of (15.2)% and (13.6)% for the three and nine months ended September 30, 2019, respectively, differ from the United States statutory federal income tax rate of 21%, primarily due to the flow through of tax repairs in connection with the 2017 Wisconsin rate settlement, the impact of the protected benefits associated with the Tax Legislation, as discussed in more detail below, and wind production tax credits, partially offset by state income taxes.

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

NOTE 11—10—FAIR VALUE MEASUREMENTS

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

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

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

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

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

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

09/30/202003/31/2021 Form 10-Q1412Wisconsin Electric Power Company

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

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

NOTE 12—11—DERIVATIVE INSTRUMENTS

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

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

The following table shows our derivative assets and derivative liabilities, along with their classification on our balance sheets. NaN of our derivatives are designated as hedging instruments.

NOTE 15—14—SEGMENT INFORMATION

We use operatingnet income attributed to common shareholder to measure segment profitability and to allocate resources to our businesses. At September 30, 2020,March 31, 2021, we reported 2 segments, which are described below.

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

Our electric utility operations are engaged in the generation, distribution, and sale of electricity to customers in southeastern Wisconsin (including metropolitan Milwaukee), east central Wisconsin, and northern Wisconsin. In addition, our steam operations produce, distribute, and sell steam to customers in metropolitan Milwaukee. Prior to April 1, 2019, we also provided electric service to Tilden, who owns an iron ore mine in the Upper Peninsula of Michigan. This customer was transferred to UMERC on April1, 2019.

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

NaN significant items were reported in the other segment during the three and nine months ended September 30, 2020March 31, 2021 and 2019.2020.

NOTE 16—15—VARIABLE INTEREST ENTITIES

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

03/31/2021 Form 10-Q15Wisconsin Electric Power Company

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

Power Purchase Agreement

We have a power purchase agreement that represents a variable interest. This agreement is for 236 MWs of firm capacity from a natural gas-fired cogeneration facility, and we account for it as a finance lease. The agreement includes 0 minimum energy requirements over the remaining term of approximately two years.one year. We have examined the risks of the entity, including operations, maintenance, dispatch, financing, fuel costs, and other factors, and have determined that we are not the primary beneficiary of the entity. We do not hold an equity or debt interest in the entity, and there is 0 residual guarantee associated with the power purchase agreement.

We have $15.8$11.2 million of required capacity payments over the remaining term of this agreement. We believe that the required capacity payments under this contract will continue to be recoverable in rates, and our maximum exposure to loss is limited to these capacity payments.

NOTE 17—16—COMMITMENTS AND CONTINGENCIES

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

Unconditional Purchase Obligations

We have obligations to distribute and sell electricity and natural gas to our customers and expect to recover costs related to these obligations in future customer rates. In order to meet these obligations, we routinely enter into long-term purchase and sale commitments for various quantities and lengths of time. Our minimum future commitments related to these purchase obligations as of September 30, 2020,March 31, 2021, were approximately $9.2 billion.

Environmental Matters

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

Air Quality

National Ambient Air Quality Standards

After completing its review of the 2008 ozone standard, the EPA released a final rule in October 2015, which lowered the limit for ground-level ozone, creating a more stringent standard than the 2008 National Ambient Air Quality Standards. NAAQS. The 2015 ozone standard lowered the 8-hour limit for ground-level ozone. In December 2020, the EPA completed its 5-year review of the ozone standard and issued a final decision to retain, without any changes, the existing 2015 standard. Under Executive Order 13990, the Biden Administration ordered that all agencies review existing regulations, orders, guidance documents, policies, and similar actions promulgated, issued or adopted between January 20, 2017 and January 20, 2021. Consequently, the December 2020 decision to retain the 2015 ozone standards with 0 changes is currently under review by the EPA.

The EPA issued final nonattainment area designations for the 2015 ozone standard in April 2018. The following counties within our service territory were designated as partial nonattainment with the 2015 standard:nonattainment: Kenosha, Sheboygan, and Northern Milwaukee/Ozaukee. This re-designation was challenged in the D.C. Circuit Court of Appeals in Clean Wisconsin et al. v. U.S. Environmental Protection Agency. Petitioners in that case have argued that additional portions of Milwaukee, Waukesha, Ozaukee, and Washington Counties (among others) should be designated as nonattainment for ozone. In November 2019, the D.C. Circuit Court of Appeals heard oral arguments for that case. A decision was issued in July 2020 remanding the rule to the EPA for further evaluation. We expect that any subsequent EPA re-designation, if necessary, would take place in 2021. The State of Wisconsin submitted the "infrastructure" portion of its state implementation plan outlining how it will implement, maintain, and enforce the 2015 Ozone standard. The plan is subject to EPA review and approval. We believe we are well positioned to meet the requirements associated with the ozone standard and do not expect to incur significant costs to comply.

Mercury and Air Toxics Standards

In May 2020, the EPA finalized revisions to the Supplemental Cost Finding for the MATS rule as well as the CAA required RTR. The EPA was required by the United States Supreme Court to review both costs and benefits of complying with the MATS rule. After its review of costs, the EPA determined that it is not appropriate and necessary to regulate hazardous air pollutant emissions from power plants under Section 112 of the CAA. As a result, under the final rule, the emission standards and other requirements of the MATS rule first enacted in 2012 remain in place. The EPA did not remove coal- and oil-fired power plants from the list of sources that are regulated under Section 112. The EPA also determined that 0 revisions to MATS are warranted based on the results of the RTR. As a result, we do not expect the rule to have a material impact on our financial condition or results of operations.

Climate Change

The ACE rule became effective in September 2019. This rule provides existing coal-fired generating units with standards for achieving GHG emission reductions. The rule was finalized in conjunction with two other separate and distinct rulemakings, (1) the repeal of the Clean Power Plan, and (2) revised implementing regulations for ACE, ongoing emissions guidelines, and all future emission guidelines for existing sources issued under CAA section 111(d). Every state's plan to implement ACE is required to focus on reducing GHG emissions by improving the efficiency of fossil-fueled power plants. The rule is being litigated in challenges brought in the D.C. Circuit Court of Appeals by 22 states (including Wisconsin), local governments, and certain nongovernmental organizations. In the

meantime,In February 2021, the Wisconsin Department of Natural Resources continues to work with state utilities and has begun the process of developing the implementation plan with respectproposed draft revisions to the ACE rule.Wisconsin Administrative Code to adopt the 2015 ozone standard and incorporate by reference the federal air pollution monitoring requirements related to the NAAQS. The comment period for the proposed rule revisions ended April 15, 2021. We believe that we are well positioned to meet the requirements associated with the 2015 ozone standard and do not expect to incur significant costs to comply with associated state or federal rules.

In addition to the 2015 ozone standard, in December 2018,2020, the EPA proposedcompleted its 5-year review of the 2012 standard for particulate matter, including fine particulate matter. The EPA determined that 0 revisions were necessary to the current standard. All counties within our service territory are in attainment with the 2012 standards. This determination is also subject to review under Executive Order 13990.

Climate Change

The ACE rule, effective since September 2019, was vacated by the D.C. Circuit Court of Appeals in January 2021. The ACE rule replaced the Clean Power Plan and provided existing coal-fired generating units with standards for achieving GHG emission reductions. In a memorandum issued to the EPA regional administrators in February 2021, the EPA stated that the D.C. Circuit Court decision meant 0 existing rule regulates GHG emissions from electric generating units. The EPA is currently reviewing its options for such regulations.

In January 2021, the EPA finalized a rule to revise the New Source Performance Standards for GHG emissions from new, modified, and reconstructed fossil-fueled power plants. The rule became effective March 14, 2021; however, on March 17, 2021 the EPA determined thatasked the BSER for new, modified,D.C. Circuit Court of Appeals to vacate and reconstructed coal units is highly efficient generation that would be equivalentremand the final rule. Despite this uncertainty, WEC Energy Group continues to supercritical steam conditions for larger units and subcritical steam conditions for smaller units. This proposed BSER would replace the determination from the previous rule, which identified BSER as partial carbon capture and storage. The EPA has reviewed comments and intends to take final actionmove forward on the proposed rule later in 2020.ESG Progress Plan, which is heavily focused on reducing GHG emissions.

WEC Energy Group has a plan (referred to as itsThe ESG progress plan), which includes us, thatProgress Plan includes the retirement of older, fossil-fueled generation, to be replaced with the construction of zero-carbon emitting renewable generationzero-carbon-emitting renewables and clean natural gas-fired generation.gas-fueled generation by 2025. By the end of 2020, WEC Energy Group was able to reduce CO2 emissions from its electric generation fleet more than 50% below 2005 levels. As a result, WEC Energy Group announced new goals in May 2021. WEC Energy Group is committing to a 60% reduction in carbon emissions from its electric generation fleet by 2025 and an 80% reduction by the end of 2030, both from a 2005 baseline. WEC Energy Group expects to achieve these goals by making operating refinements, retiring less efficient generating units, and executing its capital plan. Over the longer term, the target for WEC Energy Group's generation fleet is net-zero carbon emissions by 2050. We have already retired approximately 1,500 MW of coal-fired generation since the beginning of 2018, which included the 2019 retirement2018. As part of the PIPP as well as the 2018 retirement of the Pleasant Prairie power plant.ESG Progress Plan, WEC Energy Group expects to retire approximately 1,800 MW of additional fossil-fueled generation by 2025. The2025, which includes the planned retirements will contributein 2023-2024 of OCPP Units 5-8.

WEC Energy Group continues to meeting a new, near-term goal of reducingreduce methane emissions by improving its natural gas distribution system. WEC Energy Group's CO2 initial 2030 goal called for a 30% reduction in methane emissions from its electric generation by 55% below 2005 levels by 2025. In 2019,a 2011 baseline. Given advancements with renewable natural gas, WEC Energy Group met and surpassedis setting a new target across its original goalnatural gas distribution operations to achieve net-zero methane emissions by the end of reducing2030.

We are required to report our CO2 equivalent emissions by 40% below 2005 levels by 2030. In July 2020, WEC Energy Group announced a new goal to reducefrom the electric generating facilities we operate under the EPA Greenhouse Gases Reporting Program. We reported CO2 equivalent emissions of 14.3 million metric tonnes to the EPA for 2020. The level of CO2 and other GHG emissions varies from itsyear to year and is dependent on the level of electric generation and mix of fuel sources, which is determined primarily by 70% below 2005 levels by 2030 and to be net carbon neutral by 2050. In addition to retiring these older, fossil-fueled plants, WEC Energy Group expects to invest in low-cost renewable energy in Wisconsin. WEC Energy Group's plan is to replace a portiondemand, the availability of the retired capacitygenerating units, the unit cost of fuel consumed, and how our units are dispatched by building and owning a combination of clean, natural gas-fired generation and zero-carbon-emitting renewable generation facilities.MISO.

Water Quality

Clean Water Act Cooling Water Intake Structure Rule

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

We have received BTA determinations for OC 5 through OC 8 and Valley power plant. Although we currently believe that existing technology at the Port Washington Generating Station satisfies the BTA requirements, final determinations will not be made until the discharge permit is renewed for this facility, which is expected to be in 2021. We anticipate that the permit renewal will include a final BTA determination to address all of the Section 316(b) rule requirements.

As a result of past capital investments completed to address Section 316(b) compliance, we believe our fleet overall is well positioned to continue to meet thethis regulation and do not expect to incur significant additional costs to comply with this regulation.compliance costs.

Steam Electric Effluent Limitation Guidelines

The EPA's final 2015 ELG rule took effect in January 2016.2016 and was modified in 2020 to revise the treatment technology requirements related to BATW and wet FGD wastewaters at existing facilities. This rule created new requirements for several types of power plant wastewaters. The two2 new requirements that affect us relate to discharge limits for BATW and wet FGD wastewater. As a result of past capital investments, we believe our fleet is well positioned to meet the existing ELG regulations. Our power plant facilities already have advanced wastewater treatment technologies installed that meet many of the discharge limits established by this rule.

There will, however, need to be facility modifications to meet water permit requirements for the BATW systems at OC 7 and OC 8. Also, a wastewaterWastewater treatment system modification maymodifications also will be required for the wet FGD discharges and site wastewater from the 6 units that make up the OCPP and ERGS.ERGS units. Based on preliminary engineering cost estimates, we estimateexpect that compliance with the currentELG rule will require $50approximately $100 million in capital costs.

The ELG requirements for BATW and wet FGD systems were being re-evaluated by the EPA. In September 2017, the EPA issued a final rule (Postponement Rule) to postpone the earliest compliance date to November 1, 2020 for the BATW and wet FGD wastewater requirements while it re-evaluated the ELG rule. The Postponement Rule left unchanged the latest ELG rule compliance date of December 31, 2023. In August 2020, the EPA Administrator signed the ELG Reconsideration Rule to revise the treatment technology requirements related to BATW and wet FGD wastewaters at existing facilities. This rule is effective December 14, 2020 and includes provisions that:

Exempt facility owners from the new BATW and wet FGD requirements if a generating unit is retired by December 31, 2028.

Would limit the investment required to meet these new rule requirements if the coal-fueled unit has a low utilization rate where the 2-year average annual capacity utilization rating is less than 10%.

Modified the Voluntary Incentives Program to provide the certainty of more time (until December 31, 2028) to implement new requirements if a company adopts additional process changes and controls that achieve more stringent limitations on mercury, arsenic, selenium, nitrate/nitrite, bromide, and total dissolved solids in FGD wastewater.

We are currently evaluating what impact, if any, the rule may have on our estimated compliance cost of $50 million noted above.investment.

Manufactured Gas Plant Remediation

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

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

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

NOTE 19—18—REGULATORY ENVIRONMENT

Recovery of Natural Gas Costs

Due to the cold temperatures, wind, snow, and ice throughout the central part of the country during February 2021, the cost of gas purchased for our natural gas utility customers was temporarily driven significantly higher than our normal winter weather expectations. We have a regulatory mechanism in place for recovering all prudently incurred gas costs.

On March 23, 2021, we requested approval from the PSCW to recover approximately $54 million of natural gas costs in excess of the benchmark set in our gas cost recovery mechanism. On March 30, 2021, the PSCW approved our request to recover the costs over a period of three months, beginning in April 2021.

Coronavirus Disease – 2019

The global outbreak of COVID-19 was declared a pandemic by the WHO and the CDC. COVID-19 has spread globally, including throughout the United States and, in turn, our service territory. In response to the COVID-19 pandemic, Wisconsin declared a public health emergency and issued a shelter-in-place order, which has since been lifted. OnIn March 24, 2020, the PSCW issued 2 orders requiring certain actions to ensure that essential utility services were, and continue to be, available to our customers. The first order required all public utilities in the state of Wisconsin, including us, to temporarily suspend disconnections, the assessment of late fees, and deposit requirements for all customer classes. In addition, it required utilities to reconnect customers that were previously disconnected, offer deferred payment arrangements to all customers, and streamline the application process for customers applying for utility service.

In the second order issued onin March 24, 2020, the PSCW authorized Wisconsin utilities to defer expenditures and certain foregone revenues resulting from compliance with the first order, and expenditures as otherwise incurred to ensure safe, reliable, and affordable access to utility services during the declared public health emergency. The PSCW has affirmed that this authorization for deferral includes the incremental increase in uncollectible expense above what is currently being recovered in rates. As we already have a cost recovery mechanism in place to recover uncollectible expense for residential customers, this new deferral only impacts the recovery of uncollectible expense for our commercial and industrial customers. See Note 3, Credit Losses, for information regarding changes to our allowance for credit losses. As of March 31, 2021, amounts deferred related to the COVID-19 pandemic were not significant. The PSCW will review the recoverability and examine the prudency of any deferred amounts in future rate proceedings. As of September 30, 2020, we had deferred $3.2 million related to the COVID-19 pandemic.

OnIn June 26, 2020, the PSCW issued a written order providing a timeline for the lifting of the temporary provisions required in the first March 24, 2020 order. Utilities were allowed to disconnect commercial and industrial customers and require deposits for new service as of July 25, 2020 and July 31, 2020, respectively. After August 15, 2020, utilities were no longer required to offer deferred payment arrangements to all customers. Additionally, utilities were authorized to reinstate late fees except for the period between the first order and this supplemental order. We resumed charging late payment fees in late August 2020. Late payment fees were not charged on outstanding balances that were billed between the first order and late August 2020.
03/31/2021 Form 10-Q19Wisconsin Electric Power Company

Table of Contents

TheSubsequent to the June 2020 order, the PSCW extended the moratorium on disconnections of residential customers until November 1, 2020. In accordance with Wisconsin regulations, utilities are generally not allowed to disconnect residential customers for non-payment during the winter moratorium, which beginsbegan on November 1 and endsended on April 15. Utilities arewere allowed to continue assessing late payment fees during the winter moratorium. On April 5, 2021, the PSCW issued a written order indicating that it would not extend the moratorium on disconnections further; therefore, utilities could begin disconnecting residential customers for non-payment after April 15, 2021. Utilities are required to offer a deferred payment arrangement to low-income residential customers prior to disconnecting service. The order also allows us to resume charging late payment fees on the full balance of all outstanding arrears, regardless of the associated dates the service was provided, after April 15, 2021.

2022 Rates

On March 30, 2021, we filed an application with the PSCW for the approval of certain accounting treatments which, if approved, would allow us to maintain our current electric, natural gas, and steam base rates through 2022 and forego filing a rate case for one year. In connection with the request, we also entered into an agreement, dated March 23, 2021, with various stakeholders. Pursuant to the terms of the agreement, the stakeholders fully support the application, and we expect to file our next rate case by no later than May 1, 2022.

The application filed with the PSCW includes the following key proposals:

We would amortize, in 2022, certain previously deferred balances to offset approximately half of our forecasted revenue deficiency.
We would be allowed to defer any increases in tax expense due to changes in tax law that occur in 2021 and/or 2022.
We would maintain our earnings sharing mechanism for 2022, with modification. The earnings sharing mechanism would be modified to authorize us to retain 100% of the first 15 basis points of earnings above our currently authorized ROE. This modification would expire on December 31, 2022. The earnings sharing mechanism would otherwise remain as currently authorized.

We expect the PSCW to review and consider the application during the second quarter of 2021.

2020 and 2021 Rates

In March 2019, we filed an application with the PSCW to increase our retail electric, natural gas, and steam rates, effective January 1, 2020. In August 2019, we filed an application with the PSCW for approval of a settlement agreement entered into with certain intervenors to resolve several outstanding issues in our rate case. In December 2019, the PSCW issued a written order that approved the settlement agreement without material modification and addressed the remaining outstanding issues that were not included in the settlement agreement. The new rates became effective January 1, 2020.

The unprotected deferred tax benefits related to the unrecovered balances of certain of our recently retired plants and our SSR regulatory asset were used to reduce the related regulatory asset. Unprotected deferred tax benefits by their nature are eligible to be returned to customers in a manner and timeline determined to be appropriate by the PSCW.

(2)Amount includes certain deferred tax expense from the Tax Legislation. The rate order reflects all of the unprotected deferred tax expense from the Tax Legislation being amortized evenly over four years, which results in approximately $5 million of previously deferred tax expense being amortized each year. Unprotected deferred tax expense by its nature is eligible to be recovered from customers in a manner and timeline determined to be appropriate by the PSCW.

In accordance with our rate order, we filed an application with the PSCW onin July 20, 2020 to securitize $100 million of Pleasant Prairie power plant's book value, plus the carrying costs accrued on the $100 million during the securitization process and related fees. In November 2020, the PSCW issued a written order approving the application. The securitization is expected to reduce the carrying costs for the $100 million, benefiting customers. In its meeting on November 5, 2020, the PSCW verbally approved our application without any known material adverse conditions. The terms of this approval are subject to our receipt and review of the final written order from the PSCW, which we expect to receive by November 17, 2020, the statutory deadline for an order to be issued in this proceeding.

We will continue having an earnings sharing mechanism through 2021. The earnings sharing mechanism was modified from its previous structure to one that is consistent with other Wisconsin investor-owned utilities. Under the newthis earnings sharing mechanism, if we earn above our authorized ROE: (i) we retain 100.0% of earnings for the first 25 basis points above the authorized ROE; (ii) 50.0% of the next 50 basis points is refunded to customers; and (iii) 100.0% of any remaining excess earnings is refunded to customers. In addition, the rate order also requires us to maintain residential and small commercial electric and natural gas customer fixed charges at previously authorized rates and to maintain the status quo for our electric market-based rate programs for large industrial customers through 2021.

2018 and 2019 Rates

During April 2017, we, along with Wisconsin Public Service Corporation and WG, filed an application with the PSCW for approval of a settlement agreement we made with several of our commercial and industrial customers regarding 2018 and 2019 base rates. In September 2017, the PSCW issued an order that approved the settlement agreement, which froze base rates through 2019 for our electric, natural gas, and steam customers. Based on the PSCW order, our authorized ROE remained at 10.2% and our capital cost structure remained unchanged through 2019.

In addition to freezing base rates, the settlement agreement extended and expanded the electric real-time market pricing program options for large commercial and industrial customers and mitigated the continued growth of certain escrowed costs during the base rate freeze period by accelerating the recognition of certain tax benefits. We were flowing through the tax benefit of our repair-related deferred tax liabilities in 2018 and 2019, to maintain certain regulatory asset balances at their December31, 2017 levels. While we would typically follow the normalization accounting method and utilize the tax benefits of the deferred tax liabilities in rate making as an offset to rate base, benefiting customers over time, the federal tax code does allow for passing these tax repair-related benefits to ratepayers much sooner using the flow through accounting method. The flow through treatment of the repair-related deferred tax liabilities offset the negative income statement impact of holding the regulatory assets level, resulting in 0 change to net income.

09/30/2020 Form 10-Q23Wisconsin Electric Power Company

Table of Contents
Pursuant to the settlement agreement, we also agreed to keep our earnings sharing mechanism in place through 2019. Under this earnings sharing mechanism, if we earned above our authorized ROE, 50% of the first 50 basis points of additional utility earnings were required to be refunded to customers. All utility earnings above the first 50 basis points were also required to be refunded to customers.

Liquefied Natural Gas Facility

In November 2019, we filed an application with the PSCW requesting approval to construct a LNG facility. If approved, the facility would provide us with approximately 1 billion cubic feet of natural gas supply to meet anticipated peak demand without requiring the construction of additional interstate pipeline capacity. This facility is expected to reduce the likelihood of constraints on our natural gas system during the highest demand days of winter. The project is estimated to cost approximately $185 million. Commercial operation for the LNG facility is targeted for the end of 2023.

Solar Generation Project

In August 2019, we, along with an unaffiliated utility, filed an application with the PSCW for approval to acquire an ownership interest in a proposed solar project, Badger Hollow II, that will be located in Iowa County, Wisconsin. Once constructed, we will own 100 MW of this project. Our share of the cost of this project is estimated to be $130 million. The PSCW issued a written order approving the acquisition of this project in March 2020. Commercial operation of Badger Hollow II is targeted for December 2022.

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

CORPORATE DEVELOPMENTS

The following discussion should be read in conjunction with the accompanying financial statements and related notes and our 20192020 Annual Report on Form 10-K.

Introduction

We are a wholly owned subsidiary of WEC Energy Group, and derive revenues primarily from the distribution and sale of electricity and natural gas to retail customers in Wisconsin. We also provide wholesale electric service to numerous utilities and cooperatives for resale. We conduct our business primarily through our utility reportable segment. See Note 15,14, Segment Information, for more information on our reportable business segments.

Corporate Strategy

Our goal is to continue to build and sustain long-term value for our customers and WEC Energy Group's shareholders by focusing on the fundamentals of our business: environmental stewardship; reliability; operating efficiency; financial discipline; exceptional customer care; and safety. WEC Energy Group's plan, referred to as its ESG progress2021-2025 capital investment plan for efficiency, sustainability and growth, will provide usreferred to as its ESG Progress Plan, provides a roadmap for achievingto achieve this goal. It is an aggressive plan to cut emissions, maintain superior reliability, deliver significant savings for customers, and grow WEC Energy Group's and our investment in the future of energy.

Throughout its strategic planning process, WEC Energy Group takes into account important developments, risks and opportunities, including new technologies, customer preferences and commodity prices, energy resiliency efforts, and sustainability. WEC Energy Group published the results of a priority sustainability issue assessment in 2020, identifying the issues that are most important to the company and its stakeholders over the short and long terms. This risk and priority assessment has formed WEC Energy Group's direction as a company.

Creating a Cleaner EnergySustainable Future

WEC Energy Group's ESG progress planProgress Plan includes the retirement of older, fossil-fueled generation, to be replaced with the construction of zero-carbon-emitting renewable generationrenewables and clean natural gas-fired generation.generation by 2025 at its electric utilities including us. When taken together, the retirements and new investments should better balance our supply with our demand, while maintaining reliable, affordable energy for our customers. The retirements will contribute to meeting a new, near-term goal of reducing WEC Energy Group's and our goals to reduce carbon dioxide (CO2) emissions from electric generation by 55% below 2005 levels by 2025.generation.

In 2019, WEC Energy Group met and surpassed its original goal to reduce CO2 emissions by 40% below 2005 levels by 2030. In JulyBy the end of 2020, WEC Energy Group announced a new goal,was able to reduce CO2 emissions from electricityits electric generation fleet by 70%more than 50% below 2005 levelslevels. As a result, WEC Energy Group announced new goals in May 2021. WEC Energy Group is committing to a 60% reduction in carbon emissions from its electric generation fleet by 2025 and an 80% reduction by the end of 2030, both from a 2005 baseline. WEC Energy Group expects to achieve these goals by making operating refinements, retiring less efficient generating units and to be net carbon neutralexecuting its capital plan. Over the longer term, the target for its generation fleet is net-zero CO2 emissions by 2050.

WEC Energy Group has already retired more than 1,800 megawatts (MW) of coal-fired generation since the beginning of 2018, across its electric utilities, which included the 2019 retirement of the Presque Isle power plant as well as the 2018 retirement of the Pleasant Prairie power plant. As part of itsthe ESG progress plan,Progress Plan, WEC Energy Group expects to retire approximately 1,800 MW of additional fossil-fueled generation by 2025.2025, which includes the planned retirement in 2023-2024 of Oak Creek Power Plant Units 5-8.

In addition to retiring these older, fossil-fueled plants, WEC Energy Group expects to invest approximately $2 billion from 2021-2025 in low-cost renewable energy in Wisconsin. WEC Energy Group's plan is to replace a portion of the retired capacity by building and owning a combination of clean, natural gas-fired generation and zero-carbon-emitting renewable generation facilities that are anticipated to include:include the following new investments made by either us or Wisconsin Public Service Corporation (WPS) based on specific customer needs:

800 MW of utility-scale solar;
600 MW of battery storage;
100 MW of wind; and
100 MW of reciprocating internal combustion engine (RICE) natural gas-fueled generation.generation; and

WEC Energy Group also plans tothe planned purchase of 200 MW of capacity in the West Riverside Energy Center — a new, combined-cycle natural gas plant recently completed by Alliant Energy in Wisconsin. These new investments are in addition to the renewable projects currently underway.

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

In addition, we previously received approval from the Public Service Commission of Wisconsin (PSCW) to invest in 100 MW of utility-scale solar. We have partnered with an unaffiliated utility to construct a utility-scale solar project, Badger Hollow Solar Park II (Badger Hollow II), that will be locatedis expected to enter commercial operation in Iowa County, Wisconsin.December 2022. Once constructed, we will own 100 MW of the project. The Public Service Commission of Wisconsin (PSCW) issued a written order approving the acquisition of this project in March 2020. Commercial operation of Badger Hollow II is targeted for December 2022.

In December 2018, we received approval from the PSCW for two renewable energy pilot programs. The Solar Now pilot is expected to add 35 MW of solar generation to our portfolio, allowing non-profit and governmentalgovernment entities, as well as commercial and industrial customers to site utility owned solar arrays on their property. Under this program, in 2019, we constructed 5 MW of solar generationhave energized 16 Solar Now projects and are on track to constructcurrently have another three under construction, together totaling more than that in 2020.18 MW. The second program, the Dedicated Renewable Energy Resource pilot, would allow large commercial and industrial customers to access renewable resources that we would operate, adding up to 150 MW of renewables to our portfolio, and allowing these larger customers to meet their sustainability and renewable energy goals.

WEC Energy Group also has a goalcontinues to decrease the rate ofreduce methane emissions from theby improving its natural gas distribution linessystem. WEC Energy Group's initial 2030 goal called for a 30% reduction in its network by 30% per mile by the year 2030methane emissions from a 2011 baseline. Given advancements with renewable natural gas, WEC Energy Group was over half way toward meeting that goal atis setting a new target across its natural gas distribution operations to achieve net-zero methane emissions by the end of 2019. In April 2019, WEC Energy Group issued a climate report, which analyzes its GHG reduction goals with respect to international efforts to limit future global temperature increases to less than two degrees Celsius. WEC Energy Group will evaluate potential GHG reduction pathways as climate change policies and relevant technologies evolve over time.2030.

Reliability

We have made significant reliability-related investments in recent years, and in accordance with WEC Energy Group'sthe ESG progress plan,Progress Plan, expect to continue strengthening and modernizing our generation fleet and distribution networks to further improve reliability. Our investments, coupled with our commitment to operating efficiency and customer care, resulted in We Energies being recognized in 2019 by PA Consulting Group, an independent consulting firm, as the most reliable utility in the Midwest for the ninth year in a row. We Energies is the trade name under which we and Wisconsin Gas LLC, another wholly owned subsidiary of WEC Energy Group, operate.

Below are a few examples of reliability projects that are proposed.proposed or currently underway.

We plan to installare constructing approximately 46 miles of natural gas transmission main in southeastern Wisconsin. This project, which was approved in a written order by the PSCW in June 2020, has been designated as the "Lakeshore Lateral Project." The primary purpose of this project is to increase the quantity and reliability of natural gas service both on a peak day and annually, in southeastern Wisconsin. Construction forThis project, called the project is tentatively scheduled to begin during the fourth quarter of 2020, and the projectLakeshore Lateral Project, is expected to be completed by the end of 2021.

We plan to construct a liquefied natural gas (LNG) facility.facility to meet anticipated peak demand. Subject to PSCW approval, the facility would provide us with approximately one billion cubic feet of natural gas supply to meet anticipated peak demand without requiring the construction of additional interstate pipeline capacity. This facility is expected to reduce the likelihood of constraints on our natural gas system during the highest demand days of winter. Commercialcommercial operation for the LNG facility is targeted for the end of 2023.

Expected 2021 Annual Effective Tax Rate

We expect our earnings.2021 annual effective tax rate to be between 12.5% and 13.5%, which includes an estimated 10.5% effective tax rate benefit due to the amortization of unprotected excess deferred taxes in connection with our 2019 Wisconsin rate order. Excluding this estimated effective tax rate benefit, the expected 2021 range would be between 23% and 24%.

Non-GAAP Financial Measures

The discussion below addresses the operating income contribution of our utility segment and includes financial information prepared in accordance with GAAP, as well as electric margins and natural gas margins, which are not measures of financial performance under GAAP. Electric margin (electric revenues less fuel and purchased power costs) and natural gas margin (natural

gas revenues less cost of natural gas sold) are non-GAAP financial measures because they exclude other operation and maintenance expense, depreciation and amortization, and property and revenue taxes.

We believe that electric and natural gas margins provide a useful basis for evaluating utility operations since the majority of prudently incurred fuel and purchased power costs, as well as prudently incurred natural gas costs, are passed through to customers in current rates. As a result, management uses electric and natural gas margins internally when assessing the operating performance of our utility segment as these measures exclude the majority of revenue fluctuations caused by changes in these expenses. Similarly, the presentation of electric and natural gas margins herein is intended to provide supplemental information for investors regarding our operating performance.

Our electric margins and natural gas margins may not be comparable to similar measures presented by other companies. Furthermore, these measures are not intended to replace operating income as determined in accordance with GAAP as an indicator of our utility segment operating performance. Our utility segment operating income for the three months ended September 30, 2020 and 2019 was $244.6 million and $201.1 million, respectively. The operating income discussion below includes a table that provides the calculation of electric margins and natural gas margins, along with a reconciliation to utility segment operating income.

Electric Utility Margins

Electric utility margins increased $16.1 million during the third quarter of 2020, compared with the same quarter in 2019. The significant factors impacting the higher electric utility margins were:

A $25.4 million increase in margins associated with the negative impact of the flow through of tax benefits of our repair-related deferred tax liabilities during the third quarter of 2019, in accordance with a settlement agreement with the PSCW to maintain

Table of Contents
certain regulatory assets at their December 31, 2017 levels. These tax benefits were no longer in effect for 2020. This increase in margins was offset in income taxes.

A $12.3 million quarter-over-quarter positive impact from collections of fuel and purchased power costs compared with costs approved in rates. Under the Wisconsin fuel rules, our margins are impacted by under- or over-collections of certain fuel and purchased power costs that are less than a 2% price variance from the costs included in rates, and the remaining variance that exceeds the 2% variance is deferred.

A $9.0 million increase in margins related to higher residential sales volumes, primarily driven by the impact of favorable weather. As measured by cooling degree days, the third quarter of 2020 was 9.1% warmer than the same quarter in 2019. As measured by heating degree days, the third quarter of 2020 was 329.2% colder than the same quarter in 2019.

These increases in margins were partially offset by:

A $17.8 million net decrease in margins related to the impact of our rate order approved by the PSCW, effective January 1, 2020. This decrease in margins includes the impact related to the Tax Legislation, including unprotected tax benefits, which we agreed to return to customers and is offset in income taxes.

A $9.8 million decrease in margins related to other revenues, which included late payment charges and revenues from third party use of our assets.

Natural Gas Utility Margins

Natural gas utility margins increased $2.7 million during the third quarter of 2020, compared with the same quarter in 2019. The most significant factor impacting the higher natural gas utility margins was an increase related to the impact of our rate order approved by the PSCW, effective January 1, 2020. This increase in margins includes the impact related to the Tax Legislation, including unprotected tax benefits, which we agreed to return to customers and is offset in income taxes.

Operating Income

Operating income at the utility segment increased $43.5 million during the third quarter of 2020, compared with the same quarter in 2019. This increase was driven by $24.7 million of lower operating expenses (which include other operation and maintenance, depreciation and amortization, and property and revenue taxes), and the $18.8 million increase in margins discussed above.

The significant factors impacting the decrease in operating expenses during the third quarter of 2020, compared with the same quarter in 2019, were:

A $17.5 million decrease in transmission expense associated with the May 2018 order from the PSCW related to our required treatment of the benefits associated with the Tax Legislation, as discussed in the notes under the other operation and maintenance table above. This decrease in transmission expense was offset by a corresponding decrease in margins.

A $16.5 million decrease in transmission expense related to the flow through of tax repairs during the third quarter of 2019, as discussed in the notes under the other operation and maintenance table above.This decrease in transmission expense was offset in income taxes.

A $9.5 million decrease in regulatory amortizations and other pass through expenses, as discussed in the notes under the other operation and maintenance table above.

A $7.6 million decrease in other operation and maintenance expense related to the We Power leases, as discussed in the notes under the other operation and maintenance table above.

A $7.6 million decrease in electric and natural gas distribution expenses,driven by lower maintenance and storm restoration expense, as well as our focus on operating efficiency.

These decreases in operating expenses were partially offset by:

A $21.6 million increase in transmission expense as approved in the PSCW's 2019 rate order, which was effective January 1, 2020. See the notes under the other operation and maintenance table above for more information.

An $11.5 million increase in depreciation and amortization, driven by assets being placed into service as we continue to execute on our capital plan as well as an increase related to the We Power leases.

Other income, net decreased $0.1 million during the third quarter of 2020, compared with the same quarter in 2019. The decrease was primarily driven by the 2019 deferral of costs that were offset in other income statement line items and had no impact on net income. Mostly offsetting this decrease were higher net credits from the non-service components of our net periodic pension and OPEB costs and higher AFUDC–Equity due to continued capital investment. See Note 14, Employee Benefits, for more information on our benefit costs.

Interest Expense
Three Months Ended September 30

Interest expense$116.3 $119.3 $3.0 

Interest expense decreased $3.0 million during the third quarter of 2020, compared with the same quarter in 2019, primarily due to lower interest expense on finance lease liabilities. Also contributing to the decrease was the lower interest rate on the long-term debt issued in December 2019, which was used to repay maturing long-term debt that had a higher interest rate.

Income Tax Expense (Benefit)
 Three Months Ended September 30

Effective tax rate14.3 %(15.2)%(29.5)%

Our effective tax rate increased by 29.5% during the third quarter of 2020, compared with the same quarter in 2019. The increase was primarily due to the benefit from the flow through of tax repairs during the third quarter of 2019, in connection with the 2017 Wisconsin rate settlement. This increase in our effective tax rate was partially offset by the 2020 amortization of the unprotected excess deferred tax benefits from the Tax Legislation in connection with our Wisconsin rate order approved by the PSCW, effective January 1, 2020. These items did not impact earnings as they were offset in operating income. See Note 10, Income Taxes, and Note 19, Regulatory Environment, for more information.

(1)Represents transmission expense that we are authorized to collect in rates, in accordance with the PSCW's approval of escrow accounting for ATCAmerican Transmission Company LLC and MISO network transmission expenses. As a result, we defer as a regulatory asset or liability, the difference between actual transmission costs and those included in rates until recovery or refund is authorized in a future rate proceeding. During the nine months ended September 30,first quarter of 2021 and 2020, and 2019, $235.3$86.9 million and $249.0$78.6 million, respectively, of costs were billed to us by transmission providers.

(2)Represents costs associated with the We Power generation units, including operating and maintenance costs we recognized. During the nine months ended September 30,first quarter of 2021 and 2020, and 2019, $84.7$25.9 million and $103.0$35.1 million, respectively, of operating and maintenance costs were billed to or incurred by us related to the We Power generation units, with the difference in costs billed or incurred and expenses recognized, either deferred or deducted from the regulatory asset.

(3)Regulatory amortizations and other pass through expenses are substantially offset in margins and therefore do not have a significant impact on operatingnet income.

(4)Represents additional transmission expense recorded in 2019 associated with the May 2018 PSCW order requiring us to use 80% of our current 2018 tax benefit, including the amortization associated with the revaluation of deferred taxes, to reduce our transmission regulatory asset balance. Since our transmission regulatory asset was eliminated at December 31, 2019, there were no tax benefits used in 2020.

(5)Represents additional transmission expense recorded in 2019 associated with the flow through of tax benefits of our repair-related deferred tax liabilities starting in 2018 in accordance with a settlement agreement with the PSCW, to maintain certain regulatory asset balances at their December 31, 2017 levels. This decrease in expenses was offset in income taxes. Since our transmission regulatory asset was eliminated at December 31, 2019, there were no tax benefits used in 2020.

Electric Utility Margins

Electric utility margins decreased $17.3increased $15.9 million during the nine months ended September 30, 2020,first quarter of 2021, compared with the same periodquarter in 2019. The significant factors impacting2020, driven by a $16.2 million increase related to higher sales volumes, including the lower electric utility margins were:impact of colder winter weather. As measured by heating degree days, the first quarter of 2021 was 6.7% colder than the same quarter in 2020. Weather-normalized retail sales volumes also improved during the first quarter of 2021, compared with the same quarter in 2020, a sign of economic recovery in Wisconsin from the COVID-19 pandemic.

A $65.3This increase was partially offset by a $3.8 million net decrease in margins related to the impact of our rate order approved by the PSCW, effective January 1, 2020. This decrease in margins includes thea $3.6 million negative impact related to the Tax Legislation, including unprotected tax benefits,excess deferred taxes, which we agreed to return to customers over two years and is offset in income taxes. See Note 18, Regulatory Environment, for more information.

A $10.0 million net decrease in margins related to lower retail sales volumes, including the impact of weather. We recognized a $28.6 million net reduction in margins related to lower retail sales volumes driven by the COVID-19 pandemic. Sales volumes for our commercial and industrial customers decreased, primarily related to business interruptions and closings, while residential

sales volumes increased. These changes in volumes were both driven, in large part, by a shelter-in-place order issued by the state of Wisconsin during the COVID-19 pandemic. This net decrease from sales volumes was partially offset by an $18.6 million increase in margins related to favorable weather. As measured by cooling degree days, the nine months ended September 30, 2020 were 28.4% warmer than the same period in 2019.

A $4.4 million decrease in margins related to Tilden, who owns an iron ore mine in the Upper Peninsula of Michigan. Tilden was our customer but became a customer of UMERC after UMERC's new natural gas-fired generating units began commercial operation on March 31, 2019.

These decreases in margins were partially offset by:

A $76.3 million increase in margins associated with the negative impact of the flow through of tax benefits of our repair-related deferred tax liabilities during the nine months ended September 30, 2019, in accordance with a settlement agreement with the PSCW to maintain certain regulatory assets at their December 31, 2017 levels. These tax benefits were no longer in effect for 2020. This increase in margins was offset in income taxes.

A $12.2 million period-over-period positive impact from collections of fuel and purchased power costs compared with costs approved in rates. Under the Wisconsin fuel rules, our margins are impacted by under- or over-collections of certain fuel and purchased power costs that are less than a 2% price variance from the costs included in rates, and the remaining variance that exceeds the 2% variance is deferred.

Natural Gas Utility Margins

Natural gas utility margins increased $10.0 million during the nine months ended September 30, 2020, compared with the same period in 2019. The most significant factor impacting the higher natural gas utility margins was a $14.7 million increase related to the impact of our rate order approved by the PSCW, effective January 1, 2020. This increase in margins includes the impact related to the Tax Legislation, including unprotected tax benefits, which we agreed to return to customers and is offset in income taxes.

This increase in margins was partially offset by a $6.7 million net reduction in margins related to lower sales volumes, driven by warmer winter weather during 2020. As measured by heating degree days, the nine months ended September 30, 2020 were 10.2% warmer than the same period in 2019. In addition to the weather impact, the decrease in sales volumes for our commercial and industrial customers was also driven by business interruptions and closings related to, in large part, a shelter-in-place order issued by the state of Wisconsin during the COVID-19 pandemic.

Other Operating Income

Operating income at the utility segment increased $73.6 million during the nine months ended September 30, 2020, compared with the same period in 2019. The increase was driven by $80.9 million of lower operating expenses (which includeExpenses (includes other operation and maintenance, depreciation and amortization, and property and revenue taxes), partially offset by the $7.3 million net decrease in margins discussed above.

Other operating expenses at the utility segment increased $10.6 million during the first quarter of 2021, compared with the same quarter in 2020. The significant factors impacting the decreaseincrease in operating expenses during the nine months ended September 30, 2020, compared with the same period in 2019, were:

A $50.2 million decrease in transmission expense associated with the May 2018 order from the PSCW related to our required treatment of the benefits associated with the Tax Legislation, as discussed in the notes under the other operation and maintenance table above. This decrease in transmission expense was offset by a corresponding decrease in margins.

A $48.3 million decrease in transmission expense related to the flow through of tax repairs during 2019, as discussed in the notes under the other operation and maintenance table above.This decrease in transmission expense was offset in income taxes.

A $24.1 million decrease in regulatory amortizations and other pass through expenses, as discussed in the notes under the other operation and maintenance table above.

A $17.5 million decrease in other operation and maintenance expense related to the We Power leases, as discussed in the notes under the other operation and maintenance table above.
09/30/2020 Form 10-Q36Wisconsin Electric Power Company

Table of Contents

A $15.6 million decrease in electric and natural gas distribution expenses, driven by lower maintenance and storm restoration expense, as well as our focus on operating efficiency.

A $12.5 million decrease in benefit costs, primarily due to lower deferred compensation costs, stock-based compensation, and medical costs.

A $6.7 million decrease in other operation and maintenance expense at our plants, driven by the retirement of PIPP in March 2019 and reduced operation of the OCPP.

These decreases in operating expenses were partially offset by:

A $61.2 million increase in transmission expense as approved in the PSCW's 2019 rate order, which was effective January 1, 2020. See the notes under the other operation and maintenance table above for more information.

A $31.0$6.2 million increase in depreciation and amortization, driven by assets being placed into service as we continue to execute on our capital plan as well as an increase related to the We Power leases.

A $2.3 million increase in regulatory amortizations and other pass through expenses, as discussed in the notes under the other operation and maintenance table above.

A $1.7 million increase in benefit costs, primarily due to higher deferred compensation costs, partially offset by lower stock-based compensation and medical costs.

related to extreme weather conditions. This increase in natural gas costs also drove higher payments for fuel used at our plants. See Note 18, Regulatory Environment, for more information on the recovery of these natural gas costs.

An $11.8 million decrease in cash related to lower overall collections from customers. This decrease was driven by an increase in past due accounts receivable balances driven by the continued economic disruptions caused by the COVID-19 pandemic. See Note 3, Credit Losses, for more information. Other contributing factors include the impact of our rate order approved by the PSCW, effective January 1, 2020, including impacts from the Tax Legislation,a negative impact related to unprotected excess deferred tax benefits, which we agreed to return to customers. Other contributing factors include an increase in past due balances due to a moratorium on disconnections, lower sales volumes driven by both warmer winter weather during 2020 and business interruptions and closings during the COVID-19 pandemic, as well as the transfer of Tilden as a customer to UMERC on March 31, 2019.

A $32.1 million decrease in cash related to an increase in cash paid for income taxes during the nine months ended September 30, 2020, compared with the same period in 2019. This increase in cash paid for income taxes was primarily due to a one-time tax deduction for the retirement of a coal plant that occurred in 2019.

These decreases in net cash provided by operating activities were partially offset by:

A $59.3 million increase in cash related to lower payments for fuel and purchased power at our plants during the nine months ended September 30, 2020, compared with the same period in 2019. Our payments for fuel and purchased power decreased due to lower natural gas costs used to fuel our plants. The average per-unit cost of natural gas sold decreased 20.5% during the nine months ended September 30, 2020, compared to the same period in 2019. Lower fuel and purchased power costs were also driven by the retirement of PIPP in March 2019 and lower sales volumes. The lower sales volumes were driven by warmer winter weather during 2020 as well as business interruptions and closings during the COVID-19 pandemic.

Capital Resources and Requirements

Capital Resources

Liquidity

We anticipate meeting our capital requirements for our existing operations through internally generated funds and short-term borrowings, supplemented by the issuance of intermediate or long-term debt securities, depending on market conditions and other factors, and equity contributions from our parent.

We currently have access to the capital markets and have been able to generate funds internally and externally to meet our capital requirements. Our ability to attract the necessary financial capital at reasonable terms is critical to our overall strategic plan. We currently believe that we have adequate capacity to fund our operations for the foreseeable future through our existing borrowing arrangements, access to capital markets, and internally generated cash. See Factors Affecting Results, Liquidity, and Capital Resources – Coronavirus Disease – 2019, for additional information on the impacts of the COVID-19 pandemic.

We maintain a bank back-up credit facility, which provides liquidity support for our obligations with respect to commercial paper and for general corporate purposes. We review our bank back-up credit facility needs on an ongoing basis and expect to be able to
09/30/2020 Form 10-Q39Wisconsin Electric Power Company

Table of Contents
maintain adequate credit facilities to support our operations. See Note 7, Short-Term Debt and Lines of Credit, for more information on our credit facility.

Working Capital

As of September 30, 2020,March 31, 2021, our current liabilities exceeded our current assets by $104.4$325.3 million. We do not expect this to have any impact on our liquidity since we believe we have adequate back-up lines of credit in place for our ongoing operations. We also believe that we can access the capital markets to finance our construction programs and to refinance current maturities of long-term debt, if necessary.

Credit Rating Risk

We do not have any credit agreements that would require material changes in payment schedules or terminations as a result of a credit rating downgrade. However, we have certain agreements in the form of commodity contracts and employee benefit plans that could require collateral or a termination payment in the event of a credit rating change to below BBB- at S&P Global Ratings, a division of S&P Global Inc., and/or Baa3 at Moody's Investors Service, Inc. We also have other commodity contracts that, in the event of a credit rating downgrade, could result in a reduction of our unsecured credit granted by counterparties.

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

Subject to other factors affecting the credit markets as a whole, we believe our current ratings should provide a significant degree of flexibility in obtaining funds on competitive terms. However, these security ratings reflect the views of the rating agency only. An explanation of the significance of these ratings may be obtained from the rating agency. Such ratings are not a recommendation to buy, sell, or hold securities. Any rating can be revised upward or downward or withdrawn at any time by a rating agency.

If we are unable to successfully take actions to continue to manage any impactsimpact from the COVID-19 pandemic, and/or any additional adverse impacts of the Tax Legislation as a result of additional interpretations, regulations, amendments or technical corrections, these potential impacts could result in credit rating agencies placingcould place our credit ratings on negative outlook or downgradingdowngrade our credit ratings. Any such actions by credit rating agencies may make it more difficult and costly for us to issue future debt securities and certain other types of financing and could increase borrowing costs under our credit facility.

In February 2021, we, along with WPS, filed an application with the PSCW for approval to accelerate capital investments in two wind parks. Our share of the investment is expected to be approximately $85 million to repower major components of Blue Sky Green Field Wind Park, which is expected to be completed by the end of 2022.

In March 2021, we, along with WPS and an unaffiliated utility, filed an application with the PSCW for approval to acquire and construct the Darien Solar-Battery Park, a utility-scale solar-powered electric generating facility with a battery energy storage system. The project will be located in Kenosha County, Wisconsin and once constructed, we will own 187 MW of solar generation and 56 MW of battery storage of this project. If approved, our share of the cost of this project is estimated to be approximately $334 million, with construction expected to begin in late 2021 and completed by the end of 2023.

In April 2021, we, along with WPS and an unaffiliated utility, filed an application with the PSCW for approval to acquire the Koshkonong Solar-Battery Park, a utility-scale solar-powered electric generating facility with a battery energy storage system. The project will be located in Dane County, Wisconsin and once constructed, we will own 225 MW of solar generation and 124 MW of battery storage of this project. If approved, our share of the cost of this project is estimated to be approximately $487 million, with construction expected to begin in late 2022 and completed by the second quarter of 2024.

In April 2021, we, along with WPS, filed an application with the PSCW for approval to construct a natural gas-fired generation facility at WPS's existing Weston Power Plant site in northern Wisconsin. The new facility will consist of seven reciprocating internal combustion engines. Once constructed, we will own 64 MW of this project. If approved, our share of the cost of this project is estimated to be approximately $86 million, with construction expected to begin in 2022 and completed in 2023.

We plan to installare constructing approximately 46 miles of natural gas transmission main to increase the quantity and reliability of natural gas service in southeastern Wisconsin. This project, which was approved in a written order by the PSCW in June 2020, has been

designated as the "LakeshoreLakeshore Lateral Project." The primary purpose of this project is to increase the quantity and reliability of natural gas service, both on a peak day and annually, in southeastern Wisconsin. The cost of the project is estimated to be between $174 and $180 million. Construction for the project is tentatively scheduled to begin during the fourth quarter ofbegan in December 2020, and the project is expected to be completed by the end of 2021.

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

Off-Balance Sheet Arrangements

We are a party to various financial instruments with off-balance sheet risk as a part of our normal course of business, including letters of credit that primarily support our commodity contracts. We believe that these agreements do not have, and are not reasonably likely to have, a current or future material effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures, or capital resources. For additional information, see Note 7, Short-Term Debt and Lines of Credit, Note 13,12, Guarantees, and Note 16,15, Variable Interest Entities.

Contractual Obligations

For information about our commitments, see Contractual Obligations in Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations – Capital Resources and Requirements in our 20192020 Annual Report on Form 10-K. There were no material changes to our commitments outside the ordinary course of business during the ninethree months ended September 30, 2020.March 31, 2021.

FACTORS AFFECTING RESULTS, LIQUIDITY, AND CAPITAL RESOURCES

The following is a discussion of certain factors that may affect our results of operations, liquidity, and capital resources. The following discussion should be read together with the information in Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations – Factors Affecting Results, Liquidity, and Capital Resources in our 20192020 Annual Report on Form 10-K, which provides a more complete discussion of factors affecting us, including market risks and other significant risks, competitive markets, environmental matters, critical accounting policies and estimates, and other matters.

Coronavirus Disease – 2019

The global outbreak of COVID-19 was declared a pandemic by the WHO and the CDC and has spread globally, including throughout the United States. There isare still considerable uncertaintyquestions regarding the extent to which COVID-19 will spread and the extent and duration of the COVID-19 pandemic itself, as well as the measures currently in place to try to contain the virus, such as travel bans and restrictions, quarantines, and limitations on business operations.virus. Although the shelter-in-place order that was in effect for Wisconsin has expired, other orders limiting the capacity of various businesses have been adopted at the state and local levels. In addition, similar or more restrictive orders could be adopted in the future depending on how the virus continues to mutate and spread. Such measures haveThe effects of the COVID-19 pandemic and related government responses significantly disrupted economic activity in our service territory and have caused disruptions and volatility in the capital markets. See Item 1A. Risk Factors for more information on our risks related to COVID-19.territory.

Liquidity and Financial Markets

Volatility and uncertainty in the financial markets and global economy have impacted us in a number of ways. Upon the initial enactment of certain COVID-19 related shelter-in-place orders in early to mid-March 2020, commercial paper markets became more

expensive and related terms became less flexible. In response to these signs of market instability, the Federal Reserve implemented certain measures, including a reduction in its benchmark Federal Funds rate and the establishment of various programs to restore liquidity and stability into the short-term funding markets. These measures continue to have had a mitigating effect on commercial paper rates and availability. In addition, the initial disruption in the long-term debt markets as a result of the COVID-19 pandemic has subsided.

Our overall liquidity position remains strong. As of September 30, 2020, we had $499.0 million available under our credit facility, providing sufficient backing for our commercial paper program.

Pensions and Other Benefits

Our pension and OPEB plans were 97.6% funded at December 31, 2019, with total plan assets of $1,323.1 million and total benefit obligations of $1,355.6 million. There has been significant volatility in global capital markets during the COVID-19 pandemic, although the market losses recorded during the early stages of the pandemic in the first quarter of 2020 have reversed course in the second and third quarters of 2020 in response to government stimulus and relief efforts and the gradual reopening of businesses. During the nine months ended September 30, 2020, we recognized a $38 million increase in the value of long-term investments held in our pension and OPEB plan trusts as second and third quarter gains more than offset first quarter losses.

We could still see earnings volatility associated with certain other benefit plans maintained by our parent, WEC Energy Group, primarily related to performance units granted to certain of our employees, and deferred compensation plans. Certain of the liabilities associated with the deferred compensation plans are indexed to mutual funds and WEC Energy Group common stock, and the liabilities associated with outstanding performance units are indexed to WEC Energy Group common stock. These liabilities are marked to fair value through earnings each period, with earnings increasing as market prices decrease.

Allowance for Credit Losses

We evaluate the collectability of our accounts receivable and unbilled revenue balances considering a combination of factors. Risks identified that we do not believe are reflected in historical reserve percentages are assessed on a quarterly basis to determine whether further adjustments are required. Economic disruptions caused by the COVID-19 pandemic, including higher unemployment rates and the inability of some businesses to recover from the pandemic, could causehave caused a higher percentage of accounts receivable to become uncollectible. An increase in credit losses could negatively impactAlthough impacts on our results of operations related to uncollectible receivable balances are mitigated by a

regulatory mechanism and could resultcertain COVID-19 specific regulatory orders we have received, the increase in past due receivables we have experienced has resulted in higher working capital requirements.

Our exposure to credit losses for certain regulated utility customers is mitigated by a regulatory mechanism we have in place. Specifically, our residential tariffs include a mechanism for cost recovery or refund of uncollectible expense based on the difference between actual uncollectible write-offs and the amounts recovered in rates. In addition, we have received specific orders related to the deferral of certain costs (including credit losses) and foregone revenues related to the COVID-19 pandemic. The additional protections provided by these COVID-19 specific regulatory orders are still being assessed and will be subject to prudency reviews. See Note 19,18, Regulatory Environment, for more information.

Loss of Business

We have seen a decrease in the consumption of electricity and natural gas by some of our commercial and industrial customers as they continue to experience lower demand for their products and services as a result of the COVID-19 pandemic. Many businesses in our service territory still are not operating at full capacity. The extent to which this decrease in consumption will impact our results of operations and liquidity is dependent upon the duration of the COVID-19 pandemic and the ability of our customers to resume and continue normal operations.

Supply Chain and Capital Projects

We have not yet experienced a significant disruption in our supply chain as a result of the COVID-19 pandemic. However, if the pandemic significantly impacts our key suppliers’ ability to manufacture or deliver critical equipment and supplies or provide services, we could experience delays in our ability to perform certain maintenance and capital project activities.

We are not currently aware of any major delays or changes related to our capital plan as a result of the COVID-19 pandemic, although we are continuing to monitor potential impacts on an ongoing basis.

Employee Safety

The health and safety of our employees during the COVID-19 pandemic is paramount and enables us to continue to provide critical services to our customers.

We are following CDC guidelines and have taken enhanced precautions with regard to employee hygiene and facility cleanliness, imposed travel limitations on our employees, provided additional employee benefits, and implemented remote workremote-work policies where appropriate. We have activated an incident management team and updated our pandemic continuity plan, which includes identifying critical work groups and ensuring safe harborsafe-harbor plans are in place. We have minimized the unnecessary risk of exposure to COVID-19 by implementing self-quarantine measures and have adopted additional precautionary measures for our critical work groups.

Additional protocols have been implemented for our field employees who travel to customer premises in order to protect them, our customers, and the public. We have modified our work protocols to ensure compliance with social distancing and face covering recommendations.

With vaccinations now available in our service area, we continue to provide educational information to employees to encourage them to obtain a vaccine. As the number of administered vaccinations increases, we are developing a return-to-the-workplace strategy for those employees currently working remotely.

All of these safety measures have caused us to incur additional costs andthat, depending upon the duration of the COVID-19 pandemic, could have a material impact on our results of operations and liquidity.

Regulatory Environment

We have taken actions to ensure that essential utility services are available to our customers during the COVID-19 pandemic. In addition, the PSCW has issued written orders requiring certain actions by all public utilities in the state of Wisconsin. See Note 19,18, Regulatory Environment, for more information on these orders and the potential recovery of expenditures incurred as a result of the measures being taken.

Market Risks and Other Significant Risks

We are exposed to market and other significant risks as a result of the nature of our business and the environment in which we operate. See Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations – Factors Affecting Results, Liquidity, and Capital Resources – Market Risks and Other Significant Risks in our 20192020 Annual Report on Form 10-K for a discussion of significant risks applicable to us.

Environmental Matters

See Note 17,16, Commitments and Contingencies, for a discussion of certain environmental matters affecting us, including rules and regulations relating to air quality, water quality, land quality, and climate change.

Other Matters

Tax Cuts and Jobs Act of 2017

In December 2017, the Tax Legislation was signed into law. In May 2018, the PSCW issued a written order regarding how to refund certain tax savings from the Tax Legislation to our ratepayers in Wisconsin. The various remaining impacts of the Tax Legislation on our Wisconsin operations were addressed in the rate order issued by the PSCW in December 2019. See Note 19, Regulatory Environment, for more information on our December 2019 rate order. Also, the Michigan Public Service Commission approved a settlement in May 2018 with Tilden that addressed all base rate impacts of the Tax Legislation. Tilden owns the iron ore mine located in the Upper Peninsula of Michigan that we provided retail electric service to prior to April 1, 2019. In addition, the Federal Energy Regulatory Commission approved our revised formula rate tariff that incorporated the impacts of the Tax Legislation in August 2020.

ITEM 1A. RISK FACTORS

The following risk factor updates and supplements thoseThere were no material changes from the risk factors disclosed in Item 1A. Risk Factors in Part I of our 20192020 Annual Report on Form 10-K and Part II of our Quarterly Report on Form 10-Q for the quarter ended June 30, 2020.10-K.

The ongoing COVID-19 pandemic could adversely affect our business functions, financial condition, liquidity, and results of operations.

The global outbreak of COVID-19 was declared a pandemic by the WHO and the CDC and has spread globally, including throughout the United States. There is still considerable uncertainty regarding the extent to which COVID-19 will spread and the extent and duration of measures currently in place to try to contain the virus, such as travel bans and restrictions, quarantines, and limitations on business operations. Although the shelter-in-place order that was in effect in Wisconsin has expired, other orders limiting the capacity of various businesses have been adopted at the state and local levels. In addition, similar or more restrictive orders could be adopted in the future depending on how the virus continues to spread.

Such measures have significantly disrupted economic activity in our service territory and have caused disruptions and volatility in the capital markets. In addition, we are continuing to temporarily suspend disconnections for non-payment by certain customer classes. The effects of the continued outbreak of COVID-19 and related government responses have included, and may continue to include, extended disruptions to supply chains and capital markets, reduced labor availability and productivity, and a prolonged reduction in economic activity. These effects could continue to have a variety of adverse impacts on us, including continued reductions in demand for energy, particularly from commercial and industrial customers; impairment of goodwill or long-lived assets; continued decreases in revenue due to the inability to collect late fees; increased bad debt expense; impairment of our ability to develop, construct, and operate facilities; and impaired ability to successfully access funds from credit and capital markets.

Any additional effects of COVID-19 on the U.S. capital markets may significantly impact us. For example, the costs related to our pension and other post-retirement benefit plans are based in part on the value of the plans’ assets. Adverse investment performance for these assets or the failure to maintain sustained growth in pension investments over time could increase our plan costs and funding requirements. Similarly, we rely on access to the capital markets to fund some of our operations and capital requirements. To the extent that access to the capital markets is adversely affected by COVID-19, we may need to consider alternative sources of funding for our operations and for working capital, which may increase our cost of, as well as adversely impact our access to, capital.

We have taken precautions with regard to employee hygiene and facility cleanliness, imposed travel limitations on our employees, and implemented remote work policies where appropriate. Additional protocols have been implemented for our field employees who travel to customer premises in order to protect them, our customers, and the public.

Despite our efforts to manage the impacts of the COVID-19 pandemic, the extent to which COVID-19 may continue to affect us depends on factors beyond our knowledge or control. Therefore, we are currently unable to determine what additional impact the COVID-19 pandemic may have on our business plans and operations, liquidity, financial condition, and results of operations, but will continue to monitor COVID-19 developments and modify our plans as conditions change.
