Accounting Pronouncements

Recently Issued
Credit Losses In 2016, the FASB issued Financial Instruments - Credit Losses, Topic 326 (ASC Topic 326), which changes how entities account for losses on receivables and certain other assets. The guidance requires use of a current expected credit loss model, which may result in earlier recognition of credit losses than under previous accounting standards. ASC Topic 326 is effective for interim and annual periods beginning on or after Dec. 15, 2019, and will be applied on a modified-retrospective approach through a cumulative-effect adjustment to retained earnings as of Jan. 1, 2020. Xcel Energy is currently evaluating the impact of adoption of the new standard on its consolidated financial statements.
Recently Adopted
LeasesCredit Losses In 2016, the FASB issued LeasesFinancial Instruments - Credit Losses, Topic 326 (ASC Topic 326), Topic 842(ASC Topic 842), which provides newchanges how entities account for losses on receivables and certain other assets. The guidance requires use of a current expected credit loss model, which may result in earlier recognition of credit losses than under previous accounting and disclosure guidance for leasing activities, most significantly requiring that operating leases be recognized on the balance sheet. standards.
Xcel Energy adoptedimplemented the guidance on Jan. 1, 2019 utilizing the packageusing a modified-retrospective approach, recognizing a cumulative effect charge of transition practical expedients provided by the new standard, including carrying forward prior conclusions on whether agreements existing before the adoption date contain leases and whether existing leases are operating or finance leases; ASC Topic 842 refers$2 million (after tax) to capital leases as finance leases.
Specifically for land easement contracts, Xcel Energy has elected the practical expedient provided by ASU No. 2018-01 Leases: Land Easement Practical Expedient for Transition to Topic 842, and as a result, only those easement contracts entered on or after Jan. 1, 2019 will be evaluated to determine if lease treatment is appropriate.
Xcel Energy also utilized the transition practical expedient offered by ASU No. 2018-11 Leases: Targeted Improvements to implement the standard on a prospective basis. As a result, reporting periods in the consolidated financial statements beginning Jan. 1, 2019 reflect the implementation of ASC Topic 842, while prior periods continue to be reported in accordance with Leases, Topic 840 (ASC Topic 840).retained earnings. Other than first-time recognition of operating leasesan allowance for doubtful accounts on its consolidated balance sheet,accrued unbilled revenues, the implementationJan. 1, 2020, adoption of ASC Topic 842326 did not have a significant impact on Xcel Energy’s consolidated financial statements. Adoption resulted in recognition of approximately $1.7 billion of operating lease ROU assets and current/noncurrent operating lease liabilities. See Note 10 for leasing disclosures.

Regulatory differences for income tax primarily relate to the flow backcredit of excess deferred taxes to customers through the average rate assumption method and the impact of AFUDC - Equity. Quarterly variations primarily relates to the deferral of the flow back of excess deferred taxes in 2018, as a result of pending regulatory decisions. Treatment of most tax reform items was established prior to the first quarter of 2019, resulting in a reduction in deferred amounts.method. Income tax benefits associated with the flow backcredit of excess deferred credits are offset by corresponding revenue reductions and additional prepaid pension asset amortization.reductions.
Federal Audits Statute of limitations applicable to Xcel Energy’s consolidated federal income tax returns expire as follows:
Tax Year(s)Years Expiration
2009 - 2013 JuneSeptember 2020
2014 - 2016 September 2020
2017SeptemberJune 2021

In 2015, the IRS commenced an examination of tax years 2012 and 2013. In 2017, the IRS concluded the audit of tax years 2012 and 2013 and proposed an adjustment that would impact Xcel Energy’s NOL and ETR. Xcel Energy filed a protest with the IRS. As of June 30, 2019,March 31, 2020, the case has been forwarded to the Office of Appeals and Xcel Energy has recognized its best estimate of income tax expense that will result from a final resolution of this issue; however, the outcome and timing of a resolution is unknown.
In 2018, the IRS began an audit of tax years 2014 - 2016. As of June 30, 2019, noMarch 31, 2020, 0 adjustments have been proposed.
State Audits  Xcel Energy files consolidated state tax returns based on income in its major operating jurisdictions and various other state income-based tax returns.
As of June 30, 2019,March 31, 2020, Xcel Energy’s earliest open tax years (subject to examination by state taxing authorities in its major operating jurisdictions) were as follows:
State Year
Colorado 2009
Minnesota 2009
Texas 2009
Wisconsin 2014

In 2018, Wisconsin began an audit of tax years 2014 - 2016. As of June 30, 2019, noMarch 31, 2020, 0 material adjustments have been proposed.
No other state income tax audits were in progress as of June 30, 2019.March 31, 2020.
Unrecognized Benefits — Unrecognized tax benefit balance includes permanent tax positions, which if recognized would affect the annual ETR. In addition, the unrecognized tax benefit balance includes temporary tax positions for which the ultimate deductibility is highly certain, but for which there is uncertainty about the timing of such deductibility. A change in the period of deductibility would not affect the ETR but would accelerate the payment to the taxing authority to an earlier period.
Unrecognized tax benefits - permanent vs. temporary:
(Millions of Dollars) June 30, 2019 Dec. 31, 2018 March 31, 2020 Dec. 31, 2019

Net deferred tax liability associated with the unrecognized tax benefit amounts and related NOLs and tax credits carryforwards were $25$30 million at June 30, 2019March 31, 2020 and $24$29 million at Dec. 31, 2018.2019.
As the IRS Appeals and federal and state audits progress, it is reasonably possible that the amount of unrecognized tax benefit could decrease up to approximately $28 million in the next 12 months.
Payables for interest related to unrecognized tax benefits were not material and no0 amounts were accrued for penalties related to unrecognized tax benefits as of June 30, 2019March 31, 2020 or Dec. 31, 2018.2019.
7.    Earnings Per Share

Basic EPS was computed by dividing the earnings available to common shareholders by the weighted average number of common shares outstanding. Diluted EPS was computed by dividing the earnings available to common shareholders by the diluted weighted average number of common shares outstanding.
Diluted EPS reflects the potential dilution that could occur if securities or other agreements to issue common stock (i.e., common stock equivalents) were settled. The weighted average number of potentially dilutive shares outstanding used to calculate diluted EPS is calculated using the treasury stock method.


Common Stock Equivalents Xcel Energy Inc. has common stock equivalents related to forward equity agreements and time-based equity compensation awards.

Table of Contents


Stock equivalent units granted to Xcel Energy Inc.’s Board of Directors are included in common shares outstanding upon grant date as there is no further service, performance or market condition associated with these awards. Restricted stock issued to employees is included in common shares outstanding when granted.
Share-based compensation arrangements for which there is currently no dilutive impact to EPS include the following:
Equity awards subject to a performance condition; included in common shares outstanding when all necessary conditions for settlement have been satisfied by the end of the reporting period; and
Liability awards subject to a performance condition; any portions settled in shares are included in common shares outstanding upon settlement.
Diluted common shares outstanding included common stock equivalents of 1.80.8 million and 1.51.2 million for the three and six months ended June 30,March 31, 2020 and 2019, respectively (0.4 million for the three and six months ended June 30, 2018).respectively.

Fair Value of Financial Assets and Liabilities


Fair Value Measurements
Accounting guidance for fair value measurements and disclosures provides a single definition of fair value hierarchical framework for measuring assets and liabilities and requires disclosuredisclosures about assets and liabilities measured at fair value.
Level 1 Quoted prices are available in active markets A hierarchical framework for identical assets or liabilities asdisclosing the observability of the reporting date. The types ofinputs utilized in measuring assets and liabilities included in Level 1 are highly liquid and actively traded instruments with quoted prices.at fair value is established by this guidance.
Level 2 Pricing inputs are other than quoted prices in active markets, but are either directly or indirectly observable as of the reporting date. The types of assets and liabilities included in Level 2 are typically either comparable to actively traded securities or contracts, or priced with models using highly observable inputs.
Level 1 Quoted prices are available in active markets for identical assets or liabilities as of the reporting date. The types of assets and liabilities included in Level 1 are highly liquid and actively traded instruments with quoted prices;
Level 2 Pricing inputs are other than quoted prices in active markets, but are either directly or indirectly observable as of the reporting date. The types of assets and liabilities included in Level 2 are typically either comparable to actively traded securities or contracts, or priced with models using highly observable inputs; and
Level 3 Significant inputs to pricing have little or no observability as of the reporting date. The types of assets and liabilities included in Level 3 are those valued with models requiring significant management judgment or estimation.
Specific valuation methods include the following:include:
Cash equivalents The fair values of cash equivalents are generally based on cost plus accrued interest; money market funds are measured using quoted NAV.
Investments in equity securities and other funds Equity securities are valued using quoted prices in active markets. The fair values for commingled funds are measured using NAVs. The investments in commingled funds may be redeemed for NAV with proper notice. Private equity commingled fund investments require approval of the fund for any unscheduled redemption, and such redemptions may be approved or denied by the fund at its sole discretion. Unscheduled distributions from real estate commingled funds’funds investments may be redeemed with proper notice;notice, however, withdrawals may be delayed or discounted as a result of fund illiquidity.
Investments in debt securities Fair values for debt securities are determined by a third party pricing service using recent trades and observable spreads from benchmark interest rates for similar securities.
Interest rate derivatives Fair values of interest rate derivatives are based on broker quotes that utilize current market interest rate forecasts.
Commodity derivatives Methods used to measure the fair value of commodity derivative forwards and options generally utilize observable forward prices and volatilities, as well as observable pricing adjustments for specific delivery locations and are generally assigned a Level 2 classification. When contractual settlements relate to inactive delivery locations for which pricing is relatively unobservable, or extend to periods beyond those readily observable on active exchanges or quoted by brokers, the significance of the use of less observable inputsforecasts of forward prices and volatilities on a valuation is evaluated and may result in Level 3 classification.
Electric commodity derivatives held by NSP-Minnesota and SPS include transmission congestion instruments, generally referred to as FTRs. FTRs purchased from a RTO are financial instruments that entitle or obligate the holder to monthly revenues or charges based on transmission congestion across a given transmission path.
The value of an FTR is derived from, and designed to offset, the cost of transmission congestion. In addition to overall transmission load, congestion is also influenced by the operating schedules of power plants and the consumption of electricity pertinent to a given transmission path. Unplanned plant outages, scheduled plant maintenance, changes in the relative costs of fuels used in generation, weather and overall changes in demand for electricity can each impact the operating schedules of the power plants on the transmission grid and the value of an FTR.
If forecasted costs of electric transmission congestion increase or decrease for a given FTR path, the value of that particular FTR instrument will likewise increase or decrease. Given the limited observability of importantcertain inputs to the value of FTRs between auction processes, including expected plant operating schedules and retail and wholesale demand, fair value measurements for FTRs have been assigned a Level 3.
Non-trading monthly FTR settlements are included in fuel and purchased energy cost recovery mechanisms as applicable in each jurisdiction and therefore changes in the fair value of the yet to be settled portions of most FTRs are deferred as a regulatory asset or liability. Given this regulatory treatment and the limited magnitude of FTRs relative to the electric utility operations of NSP-Minnesota and SPS, the numerous unobservable quantitative inputs pertinent to the value of FTRs are insignificant to the consolidated financial statements of Xcel Energy.statements.
Non-Derivative Fair Value Measurements
The NRC requires NSP-Minnesota to maintain a portfolio of investments to fund the costs of decommissioning its nuclear generating plants. Assets of the nuclear decommissioning fund are legally restricted for the purpose of decommissioning these facilities. The fund contains cash equivalents, debt securities, equity securities and other investments. NSP-Minnesota uses the MPUC approved asset allocation for the escrow and investment targets by asset class for both the escrow and qualified trust.
NSP-Minnesota recognizes the costs of funding the decommissioning over the lives of the nuclear plants, assuming rate recovery of all costs. Realized and unrealized gains on fund investments over the life of the fund are deferred as an offset of NSP-Minnesota’s regulatory asset for nuclear decommissioning costs. Consequently, any realized and unrealized gains and losses on securities in the nuclear decommissioning fund are deferred as a component of the regulatory asset.


Unrealized gains for the nuclear decommissioning fund were $606$454 million and $450$706 million as of June 30, 2019March 31, 2020 and Dec. 31, 2018,2019, respectively, and unrealized losses were $15$88 million and $45$6 million as of June 30, 2019March 31, 2020 and Dec. 31, 2018,2019, respectively.

Derivative Instruments Fair Value Measurements
Xcel Energy enters into derivative instruments, including forward contracts, futures, swaps and options, for trading purposes and to manage risk in connection with changes in interest rates, utility commodity prices and vehicle fuel prices.
Interest Rate Derivatives Xcel Energy enters into various instruments that effectively fix the interest payments on certain floating rate debt obligations or effectively fix the yield or price on a specified benchmark interest rate for an anticipated debt issuance for a specific period. These derivative instruments are generally designated as cash flow hedges for accounting purposes.
As of June 30, 2019,March 31, 2020, Xcel Energy had $13 million of settlement payables related to interest rate swaps, which were paid in April 2020. These interest rate derivatives were designated as hedges and changes in fair value were recorded as other comprehensive income.
As of March 31, 2020, accumulated other comprehensive loss related to interest rate derivatives included $4$5 million of net losses expected to be reclassified into earnings during the next 12 months as the hedged transactions impact earnings.
As of June 30, 2019, Xcel Energy had unsettled interest rate swaps outstanding with a notional amount of $300 million. These interest rate derivatives were designated as cash flow hedges, and as such, changes in fair value are recorded to other comprehensive income.
Wholesale and Commodity Trading Risk Xcel Energy Inc.’s utility subsidiaries conduct various wholesale and commodity trading activities, including the purchase and sale of electric capacity, energy, energy-related instruments and natural gas-related instruments, including derivatives. Xcel Energy is allowed to conduct these activities within guidelines and limitations as approved by its risk management committee, comprised of management personnel not directly involved in activities governed by this policy.
Commodity Derivatives Xcel Energy enters into derivative instruments to manage variability of future cash flows from changes in commodity prices in its electric and natural gas operations, as well as for trading purposes. This could include the purchase or sale of energy or energy-related products, natural gas to generate electric energy, natural gas for resale, FTRs, vehicle fuel and weather derivatives.
Xcel Energy may enter into derivative instruments that mitigate commodity price risk on behalf of electric and natural gas customers, but may not be designated as qualifying hedging transactions. Changes in the fair value of non-trading commodity derivative instruments are recorded as other comprehensive income or deferred as a regulatory asset or liability. The classification as a regulatory asset or liability is based on commission approved regulatory recovery mechanisms.


As of June 30, 2019,March 31, 2020, Xcel Energy had no0 commodity contracts designated as cash flow hedges.
Xcel Energy also enters into commodity derivative instruments for trading purposes not directly related to commodity price risks associated with serving its electric and natural gas customers. Changes in the fair value of these commodity derivatives are recorded in electric operating revenues, net of amounts credited to customers under margin-sharing mechanisms.

Consideration of Credit Risk and Concentrations Xcel Energy continuously monitors the creditworthiness of counterparties to its interest rate derivatives and commodity derivative contracts prior to settlement, and assesses each counterparty’s ability to perform on the transactions set forth in the contracts. Impact of credit risk was immaterial to the fair value of unsettled commodity derivatives presented in the consolidated balance sheets.
Xcel Energy’s utility subsidiaries’ most significant concentrations of credit risk with particular entities or industries are contracts with counterparties to their wholesale, trading and non-trading commodity activities.
As of June 30, 2019, sixMarch 31, 2020, 6 of Xcel Energy’s 10 most significant counterparties for these activities, comprising $72$154 million, or 36%56%, of this credit exposure, had investment grade credit ratings from S&P Global Ratings, Moody’s Investor Services or Fitch Ratings. ThreeNaN of the 10 most significant counterparties, comprising $21$35 million, or 11%13%, of this credit exposure, were not rated by these external agencies, but based on Xcel Energy’s internal analysis, had credit quality consistent with investment grade. OneNaN of these significant counterparties, comprising $8$12 million or 4% of this credit exposure, had credit quality less than investment grade, based on externalinternal analysis. Nine NaN of these significant counterparties are municipal or cooperative electric entities, RTOs or other utilities.

Credit Related Contingent Features  Contract provisions for derivative instruments that the utility subsidiaries enter, including those accounted for as normal purchase-normal sale contracts and therefore not reflected on the consolidated balance sheets, may require the posting of collateral or settlement of the contracts for various reasons, including if the applicable utility subsidiary’s credit ratings are downgraded below its investment grade credit rating by any of the major credit rating agencies, or for cross default contractual provisions if there was a failure under other financing arrangements related to payment terms or other covenants. As of June 30, 2019March 31, 2020 and Dec. 31, 2018, $62019, there were $11 million and less than $1$7 million of derivative instruments were in a liability position with such underlying contract provisions, respectively, with no offsetting positions or posted collateral.

Provisions allow counterparties to seek performance assurance, including cash collateral, in the event that a given utility subsidiary’s ability to fulfill its contractual obligations is reasonably expected to be impaired. Xcel Energy had less than $1 million of0 collateral posted related to adequate assurance clauses in derivative contracts as of June 30, 2019March 31, 2020 and Dec. 31, 20182019.

10.    Commitments and Contingencies
The following include commitments, contingencies and unresolved contingencies that are material to Xcel Energy’s financial position.
Legal
Xcel Energy is involved in various litigation matters in the ordinary course of business. The assessment of whether a loss is probable or is a reasonable possibility, and whether the loss or a range of loss is estimable, often involves a series of complex judgments about future events. Management maintains accruals for losses probable of being incurred and subject to reasonable estimation. Management is sometimes unable to estimate an amount or range of a reasonably possible loss in certain situations, including but not limited to when (1) the damages sought are indeterminate, (2) the proceedings are in the early stages, or (3) the matters involve novel or unsettled legal theories.

19

Table of Contents


In such cases, there is considerable uncertainty regarding the timing or ultimate resolution of such matters, including a possible eventual loss. For current proceedings not specifically reported herein, management does not anticipate that the ultimate liabilities, if any, would have a material effect on Xcel Energy’s financial statements. Unless otherwise required by GAAP, legal fees are expensed as incurred.
Gas Trading Litigation e prime is a wholly owned subsidiary of Xcel Energy. e prime was in the business of natural gas trading and marketing but has not engaged in natural gas trading or marketing activities since 2003.  Multiple lawsuits seeking monetary damages were commenced against e prime and its affiliates, including Xcel Energy, between 2003 and 2009 alleging fraud and anticompetitive activities in conspiring to restrain the trade of natural gas and manipulate natural gas prices. Cases were all consolidated in the U.S. District Court in Nevada.
Two NaN cases remain active which include an MDL matter consisting of a Colorado purported class (Breckenridge) and a Wisconsin purported class (Arandell Corp.).
Breckenridge/Colorado - The— In February 2019, the MDL panel remanded Breckenridge back to the U.S. District Court in Colorado and assigned to a judge.Colorado.
Arandell Corp. - In February 2019, Xcel Energy filed a no opposition motion to have the case was remanded back to the U.S. District Court in Wisconsin. The motion was granted andPlaintiffs are seeking class certification. It is uncertain when the case has been remanded back to the District Court.court will rule on this issue.
Xcel Energy has concluded that a loss is remote for both remaining lawsuits.
Line Extension Disputes — In December 2015, the DRC filed a lawsuit seeking monetary damages in the Denver District Court, stating PSCo failed to award proper allowances and refunds for line extensions to new developments pursuant to the terms of electric and gas service agreements. The dispute involves claims by over fifty developers. In February 2018, the Colorado Supreme Court denied DRC’s petition to appeal the Denver District Court’s dismissal of the lawsuit, effectively terminating this litigation. However, in January 2018, DRC filed a new lawsuit in Boulder County District Court, asserting a single claim that PSCo was required to file its line extension agreements with the CPUC but failed to do so.
This claim is similar to the arguments previously raised by DRC. PSCo filed a motion to dismiss this claim, which was granted in May 2018. DRC subsequently filed an appeal to the Colorado Court of Appeals. Briefs have been filed and it is uncertain when a decision will be rendered.
PSCo has concluded that a loss is remote with respect to both of these matters as the service agreements were developed to implement CPUC approved tariffs and PSCo has complied with the tariff provisions. If a loss were sustained, PSCo believes it would be allowed to recover costs through traditional regulatory mechanisms. Amount or range in dispute is presently unknown and no accrual has been recorded for this matter.
Rate Matters
MEC Transactions In November 2018, NSP-Minnesota reached an agreement with Southern Power Company (a subsidiary of Southern Company) to purchase MEC, a 760 MW natural gas combined cycle facility, for approximately $650 million. In September 2019, the MPUC denied NSP-Minnesota's request to purchase MEC as a rate base asset. In January 2020, the MPUC approved Xcel Energy’s plan to acquire MEC as a non-regulated investment and step into the existing PPAs with NSP-Minnesota. A newly formed non-regulated subsidiary of Xcel Energy completed the transaction to purchase MEC in January 2020.
In April 2020, Xcel Energy reached agreement to sell MEC to Southwest Generation for $680 million, subject to working capital adjustments. Proceeds from the sale will primarily be used to reduce Xcel Energy’s overall financing needs. The transaction is not anticipated to have a material impact on long-term earnings per share and is expected to close in the third quarter of 2020.
The sale will result in a gain, which Xcel Energy plans to use to fund its corporate giving efforts, including support related to COVID-19 recovery.
NSP-MinnesotaSherco In NSP-Minnesota’s 2013 fuel reconciliation filing, the MPUC made recovery of replacement power costs associated with the 2011 incident at its Sherco Unit 3 plant provisional and subject to further review following conclusion of litigation commenced by NSP-Minnesota, SMMPA (Co-owner of Sherco Unit 3) and insurance companies against GE.
In 2018, NSP-Minnesota and SMMPA reached a settlement with GE. NSP-Minnesota has notified the MPUC of its proposal to refund the GE settlement proceeds back to customers through the FCA.
The insurance providers continued their litigation against GE and the case went to trial.
In 2018, GE prevailed in the lawsuit with the insurance companies, however, the jury found comparable fault, finding that GE was 52% and NSP-Minnesota was 48% at fault. At that point in the litigation, NSP-Minnesota was no longer involved in the case and was not present to make arguments about its role in the event. The specific issue leading to the fault apportionment was also not before the jury and not relevant to the outcome of the trial.
In January 2019, the DOC recommended that NSP-Minnesota refund $20 million of previously recovered purchased power costs to its customers, based on the jury’s apportionment of fault. The OAG recommended the MPUC withhold any decision until the underlying litigation by the insurance providers (currently under appeal) is concluded. The DOC subsequently agreedfiled comments agreeing with the OAG’s recommendation to withhold a decision pending the outcome of any appeals. NSP-Minnesota filed reply comments arguing that the DOC recommendations are without merit and that it acted prudently in operating the plant and its settlement with GE was reasonable.
In March 2019, the MPUC approved NSP-Minnesota’s proposal to refund the GE settlement proceeds back to customers through the FCA. It also decided to withhold any decision as to NSP-Minnesota’s prudence in connection with the incident at Sherco Unit 3 until after conclusion of the pending litigation between GE and NSP-Minnesota’s insurers. The lower court’s decision was affirmed on appeal. In March 2020, NSP-Minnesota’s insurers filed a petition seeking additional review by the Minnesota Supreme Court, which remains pending.
MISO ROE Complaints — In November 2013 and February 2015, customers filed complaints against MISO TOs including NSP-Minnesota and NSP-Wisconsin. The first complaint argued for a reduction in the base ROE in MISO


transmission formula rates from 12.38% to 9.15%, and removal of ROE adders (including those for RTO membership). The second complaint sought to reduce base ROE from 12.38% to 8.67%.
In September 2016, the FERC issued an order granting a 10.32% base ROE (10.82% with the RTO adder) effective for the first complaint period of Nov. 12, 2013 to Feb. 11, 2015 and subsequent to the date of the order. The D.C. Circuit subsequently vacated and remanded FERC Opinion No. 531, which had established the ROE methodology on which the September 2016 FERC order was based.
In October 2018, the FERC issued an ROE order that addressed the D.C. Circuit’s actions. Under a new proposed two step ROE approach, the FERC indicated an intention to dismiss an ROE complaint if the existing ROE falls within the range of just and reasonable ROEs based on equal weighting of the DCF, CAPM, and Expected Earnings models. The FERC proposed that if necessary, it would then set a new ROE by averaging the results of these models plus a Risk Premium model.
The FERC subsequently made preliminary determinations in a November 2018 order that the MISO TO’s base ROE in effect for the first complaint period (12.38%) was outside the range of reasonableness, and should be reduced. The FERC indicated its preliminary analysis using the new ROE approach resulted in a base ROE of 10.28% for the first complaint period, compared to the previously ordered base ROE of 10.32%. NSP-Minnesota has recognized a current refund liability consistent with its best estimate of the final ROE, pending further FERC action as early as the second half of 2019.

On March 21, 2019, the FERC announced a NOI seeking public comments on whether, and if so how, to revise ROE policies in light of the D.C. Circuit Court decision. FERC also initiated a NOI on whether to revise its policies on incentives for electric transmission investments, including the RTO membership incentive. Initial comments
In November 2019, the FERC issued an order adopting a new ROE methodology and settling the MISO base ROE at 9.88% (10.38% with the RTO adder), effective Sept. 28, 2016 and for the Nov. 12, 2013 to Feb. 11, 2015 refund period. The FERC also dismissed the second complaint. In December 2019, MISO TOs filed a request for rehearing. Customers also filed requests for rehearing claiming, among other points, that the FERC erred by dismissing the second complaint without refunds.
FERC accepted the requests for rehearing in January 2020, however, it is uncertain when the FERC will act on boththe requests or any other pending matters related to the 2019 NOIs were due in June 2019, with reply comments due. NSP-Minnesota has recognized a liability for its best estimate of final refunds to customers.
In March 2020, the FERC issued a Notice of Proposed Rulemaking regarding changes to its policies for transmission incentives, including a proposal to increase the RTO participation adder from 50 to 100 basis points and to make the adder available regardless of whether a utility’s ongoing participation in the third quarter of 2019, pending further FERC actionRTO is voluntary or required by legislation or a regulator. It is uncertain if or when this change will be adopted and implemented as early as the second half of 2019.a final order.
SPP OATT Upgrade Costs — Under the SPP OATT, costs of transmission upgrades may be recovered from other SPP customers whose transmission service depends on capacity enabled by the upgrade. SPP had not been charging its customers for these upgrades, even though the SPP OATT had allowed SPP to do so since 2008. In 2016, the FERC granted SPP’s request to recover these previously unbilled charges and SPP subsequently billed SPS approximately $13 million.
In July 2018, SPS’ appeal to the D.C. Circuit over the FERC rulings granting SPP the right to recover these previously unbilled charges was remanded to the FERC. In February 2019, the FERC reversed its 2016 decision and ordered SPP to refund the charges retroactively collected from its transmission customers, including SPS, related to periods before Sept.September 2015. In April 2019, several parties, including SPP, filed requests for a rehearing. In February 2020, FERC issued an order rejecting all rehearing requests and providing certain clarifications. In March 2020, SPP and Oklahoma Gas & Electric separately filed petitions for review of FERC’s orders at the D.C. Circuit. SPS has intervened in both appeals in support of FERC. The timing of a FERC response to the rehearing requestsan appeals decision is uncertain. Any refunds received by SPS are expected to be given back to SPS customers through future rates.
In October 2017, SPS filed a separate complaint against SPP asserting that SPP has assessed upgrade charges to SPS in violation of the SPP OATT. The FERC granted a rehearing for further consideration in May 2018. The timing of FERC action on the SPS rehearing is uncertain. If SPS’ complaint results in additional charges or refunds, SPS will seek to recover or refund the amounts through future SPS customer rates.
Environmental
MGP, Landfill and Disposal Sites
Ashland MGP Site — NSP-Wisconsin was named a responsible party for contamination at the Ashland/Northern States Power Lakefront Superfund Site (the Site) in Ashland, Wisconsin. Remediation was completed in 2019 and restoration activities are anticipated to be completed in 2019 and groundwater2020. Groundwater treatment activities will continue for many years.
The current cost estimate for remediation and restoration of the entire site is approximately $190$199 million. At June 30, 2019March 31, 2020 and Dec. 31, 2018, NSP-Wisconsin2019, NSP‑Wisconsin had a total liability of $26$22 million and $27$23 million, respectively, for the entire site.
NSP-Wisconsin has deferred the unrecovered portion of the estimated Site remediation and restoration costs as a regulatory asset. The PSCW has authorized NSP-Wisconsin rate recovery for all remediation and restoration costs incurred at the Site. In 2012,its final December 2019 order approving 2020 and 2021 natural gas base rates, the PSCW agreed to allow NSP-Wisconsin to pre-collect certainauthorized continued amortization of costs to amortize costs over 10 years and to applyapplication of a 3% carrying costcharge to the unamortized regulatory asset.
Rice Yards (Denver ) MGP Landfill or Disposal SitesSite — PSCo is cooperating with the City of Denver on an environmental investigation of the Rice Yards Site in the Central Platte Valley of Denver, Colorado, which had various historic industrial uses by multiple parties, including railroad, maintenance shop, scrap metal yard and MGP operations. In the 1990’s, environmental remediation activities took place at the site under state oversight to accommodate the development of an amusement park and parking lots.
The area is being redeveloped into residential and commercial mixed uses, and PSCo is in discussions with the current property owner regarding legal claims related to the Rice Yards Site.
In addition to the Rice Yards and Ashland Sites, Xcel Energy is currently investigating, remediating or remediatingperforming post-closure actions at 11 other MGP, landfill or other disposal sites across its service territories.
Xcel Energy has recognized its best estimate of costs/liabilities that will result from final resolution of these issues, however, the outcome and timing is unknown.  In addition, there may be insurance recovery and/or recovery from other potentially responsible parties, offsetting a portion of the costs incurred.


Environmental Requirements — Water and Waste
Coal Ash Regulation — Xcel Energy’s operations are subject to federal and state lawsregulations that impose requirements for handling, storage, treatment and disposal of solid waste.
Under the CCR Rule, utilities are required to complete groundwater sampling around their CCR landfills and surface impoundments. By the end of 2019, only nine ofCurrently, Xcel Energy’sEnergy has 9 regulated ash units are expected to be in operation.
Xcel Energy is conducting groundwater sampling and, where appropriate, initiating theimplementing assessment of corrective measures at certain CCR landfills and surface impoundments. In 2019, groundwater monitoring consistent with the CCR Rule was conducted. In NSP-Minnesota, 0 results above the groundwater protection standards in the rule were identified. In PSCo, statistically significant increases above background concentrations were detected at 4 locations. Subsequently, assessment monitoring samples were collected, and PSCo is evaluating whetheroptions for corrective action is required at any CCR landfills or surface impoundments.
2 locations. Until Xcel EnergyPSCo completes its assessment, it is uncertain what impact, if any, there will be on the operations, financial condition or cash flows.
In August 2018, the D.C. Circuit ruled that the EPA cannot allow utilities to continue to use unlined impoundments (including clay lined impoundments) for the storage or disposal of coal ash. In November 2019, the EPA proposed rules in response to this decision. If finalized in their current form, these rules would require NSP-Minnesota to expedite closure plans for 1 impoundment at an estimated cost of $4 million and the construction of a new impoundment at the cost of $8 million. In 2019, NSP-Minnesota initiated the construction of this new impoundment, an ash pond, expected to be in service in 2020. Upon placing the new ash pond in service, the existing ash pond will be taken out of service, and closure activities as prescribed by the CCR Rule and the facility’s National Pollutant Discharge Elimination System permit will be initiated.
In addition, the rules proposed by the EPA under the D.C. Circuit ruling may require PSCo to expedite the closure of 1 coal ash impoundment that was not previously required to close. PSCo is pursuing options through comment on the proposed rules or some other means to allow continued operation of this impoundment until the generating units are retired in 2025, at which time the impoundment would be closed.
Closure costs for existing impoundments are included in the calculation of the asset retirement obligation liability.
Leases
Xcel Energy evaluates contracts that may contain leases, including PPAs and arrangements for the use of office space and other facilities, vehicles and equipment. Under ASC Topic 842, adopted by Xcel Energy on Jan. 1, 2019, a contract contains a lease if it conveys the exclusive right to control the use of a specific asset. A contract determined to contain a lease is evaluated further to determine if the arrangement is a finance lease.
ROU assets represent Xcel Energy's rights to use leased assets. Starting in 2019, the present value of future operating lease payments are recognized in other current liabilities and noncurrent operating lease liabilities. These amounts, adjusted for any prepayments or incentives, are recognized as operating lease ROU assets.
Most of Xcel Energy’s leases do not contain a readily determinable discount rate. Therefore, the present value of future lease payments is calculated using the applicable Xcel Energy subsidiary’s estimated incremental borrowing rate (weighted-average of 4.1%). Xcel Energy has elected the practical expedient under which non-lease components, such as asset maintenance costs included in payments, are not deducted from minimum lease payments for the purposes of lease accounting and disclosure.
Leases with an initial term of 12 months or less are classified as short-term leases and are not recognized on the consolidated balance sheet.

PPAs $1,642
Other 201
Gross operating lease ROU assets 1,843

In 2019, ROU assets for finance leases are included in other noncurrent assets, and the present value of future finance lease payments is included in other current liabilities and other noncurrent liabilities. Prior to 2019, finance leases were included in property, plant and equipment, the current portion of long-term debt and long-term debt.

Variable Interest EntitiesVIEs
Under certain PPAs, NSP-Minnesota, PSCo and SPS purchase power from IPPs andfor which the utility subsidiaries are required to reimburse the IPPs for natural gas or biomass fuel costs, or to participate in tolling arrangements under which the utility subsidiaries procure the natural gas required to produce the energy that they purchase. These specific PPAs create a variable interest in the associated IPP.
The Xcel Energy utility subsidiaries had approximately 3,9863,266 MW and 3,7703,986 MW of capacity under long-termlong‑term PPAs as of June 30, 2019at March 31, 2020 and Dec. 31, 2018,2019, respectively, with entities that have been determined to be variable interest entities.VIEs. Xcel Energy has concluded that these entities are not required to be consolidated in its consolidated financial statements because it does not have the power to direct the activities that most significantly impact the entities’ economic performance.

12.    Segment Information
Regulated electric utility operating results of NSP-Minnesota, NSP-Wisconsin, PSCo and SPS, as well as the regulated natural gas utility operating results of NSP-Minnesota, NSP-Wisconsin and PSCo are each separately and regularly reviewed by Xcel Energy’s chief operating decision maker. Xcel Energy evaluates performance by each utility subsidiary based on profit or loss generated from the product or service provided.provided, including the regulated
electric utility operating results of NSP-Minnesota, NSP-Wisconsin, PSCo and
SPS, as well as the regulated natural gas utility operating results of NSP‑Minnesota, NSP-Wisconsin and PSCo. These segments are managed separately because the revenue streams are dependent upon regulated rate recovery, which is separately determined for each segment.

Xcel Energy has the following reportable segments:
Regulated Electric - The regulated electric utility segment generates, transmits and distributes electricity in Minnesota, Wisconsin, Michigan, North Dakota, South Dakota, Colorado, Texas and New Mexico. In addition, this segment includes sales for resale and provides wholesale transmission service to various entities in the United States. The regulated electric utility segment also includes wholesale commodity and trading operations.operations; and
Regulated Natural Gas - The regulated natural gas utility segment transports, stores and distributes natural gas primarily in portions of Minnesota, Wisconsin, North Dakota, Michigan and Colorado.
Xcel Energy presents Other, which includes operating segments, with revenues below the necessary quantitative thresholds. Those operating segments primarily include steam revenue, appliance repair services, non‑utility real estate activities, revenues associated with processing solid waste into refuse-derived fuel and investments in rental housing projects that qualify for low-income housing tax credits.

23



All Other - Operating segments with revenues below the necessary quantitative thresholds are included in this category. Those segments primarily include steam revenue, appliance repair services, non-utility real estate activities, revenues associated with processing solid waste into refuse-derived fuel and investments in rental housing projects that qualify for low-income housing tax credits.
Xcel Energy had equity investments in unconsolidated subsidiaries of $145$158 million and $141$155 million as of June 30, 2019March 31, 2020 and Dec. 31, 2018,2019, respectively, included in the natural gas utility and all other segments.
Asset and capital expenditure information is not provided for Xcel Energy’s reportable segments. As an integrated electric and natural gas utility, Xcel Energy operates significant assets that are not dedicated to a specific business segment. Reporting assets and capital expenditures by business segment would require arbitrary and potentially misleading allocations which may not necessarily reflect the assets that would be required for the operation of the business segments on a stand-alone basis.
Certain costs, such as common depreciation, common O&M expenses and interest expense are allocated based on cost causation allocators across each segment. In addition, a general allocator is used for certain general and administrative expenses, including office supplies, rent, property insurance and general advertising.

Item
ITEM 2 — MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
The following discussion and analysis by management focuses on those factors that had a material effect on Xcel Energy’s financial condition, results of operations and cash flows during the periods presented, or are expected to have a material impact in the future. It should be read in conjunction with the accompanying unaudited consolidated financial statements and the related notes to consolidated financial statements.
Due to the seasonality of Xcel Energy’s operating results, quarterly financial results are not an appropriate base from which to project annual results. The demand for electric power and natural gas is affected by seasonal differences in the weather. In general, peak sales of electricity occur in the summer months, and peak sales of natural gas occur in the winter months. As a result, the overall operating results may fluctuate substantially on a seasonal basis. Additionally, Xcel Energy’s operations have historically generated less revenues and income when weather conditions are milder in the winter and cooler in the summer.
Non-GAAP Financial Measures
The following discussion includes financial information prepared in accordance with GAAP, as well as certain non-GAAP financial measures such as electric margin, natural gas margin, ongoing earnings and ongoing diluted EPS. Generally, a non-GAAP financial measure is a measure of a company’s financial performance, financial position or cash flows that excludes (or includes) amounts that are adjusted from measures calculated and presented in accordance with GAAP. Xcel Energy’s management uses non-GAAP measures for financial planning and analysis, for reporting of results to the Board of Directors, in determining performance-based compensation, and communicating its earnings outlook to analysts and investors. Non-GAAP financial measures are intended to supplement investors’ understanding of our performance and should not be considered alternatives for financial measures presented in accordance with GAAP. These measures are discussed in more detail below and may not be comparable to other companies’ similarly titled non-GAAP financial measures.

Table of Contents


Electric and Natural Gas Margins
Electric margin is presented as electric revenues less electric fuel and purchased power expenses. Natural gas margin is presented as natural gas revenues less the cost of natural gas sold and transported. Expenses incurred for electric fuel and purchased power and the cost of natural gas are generally recovered through various regulatory recovery mechanisms. As a result, changes in these expenses are generally offset in operating revenues.
Management believes electric and natural gas margins provide the most meaningful basis for evaluating our operations because they exclude the revenue impact of fluctuations in these expenses. These margins can be reconciled to operating income, a GAAP measure, by including other operating revenues, cost of sales - other, O&M expenses, conservation and DSM expenses, depreciation and amortization and taxes (other than income taxes).
Earnings Adjusted for Certain Items (Ongoing Earnings and Ongoing Diluted EPS)
GAAP diluted EPS reflects the potential dilution that could occur if securities or other agreements to issue common stock (i.e., common stock equivalents) were settled. The weighted average number of potentially dilutive shares outstanding used to calculate Xcel Energy Inc.’s diluted EPS is calculated using the treasury stock method. Ongoing earnings reflect adjustments to GAAP earnings (net income) for certain items.
Ongoing diluted EPS is calculated by dividing the net income or loss of each subsidiary, adjusted for certain items, by the weighted average fully diluted Xcel Energy Inc. common shares outstanding for the period. Ongoing diluted EPS for each subsidiary is calculated by dividing the net income or loss of such subsidiary, adjusted for certain items, by the weighted average fully diluted Xcel Energy Inc. common shares outstanding for the period.
We use these non-GAAP financial measures to evaluate and provide details of Xcel Energy’s core earnings and underlying performance. We believe these measurements are useful to investors to evaluate the actual and projected financial performance and contribution of our subsidiaries.
For the three and six months ended June 30,March 31, 2020 and 2019, and 2018, there were no such adjustments to GAAP earnings and therefore GAAP earnings equal ongoing earnings for these periods.
Results of Operations
The only common equity securities that are publicly traded are common shares of Xcel Energy Inc. Diluted earnings and EPS of each subsidiary discussed below do not represent a direct legal interest in the assets and liabilities allocated to such subsidiary but rather represent a direct interest in our assets and liabilities as a whole.

Summary of Earnings
Xcel Energy — Xcel Energy’s earnings decreased $0.06$0.05 per share for the secondfirst quarter of 2019 and $0.02 per share year-to-date.2020. Earnings reflect higher electric and natural gas margins primarily due to non-fuel riders and regulatory rate outcomes, more than offset by 5 cents per sharethe negative impact of unfavorable weather, increased depreciation, interest and operating and maintenance expenses.weather. The impact of COVID-19 did not significantly impact first quarter 2020 results, but could have a material impact on our financial results going forward. See COVID-19 section below for further discussion.
PSCo — Earnings decreased $0.04$0.03 per share for the secondfirst quarter of 20192020, reflecting lower natural gas margins primarily due to unfavorable weather, higher depreciation and $0.03O&M, partially offset by higher electric margin and AFUDC.
NSP-Minnesota — Earnings decreased $0.02 per share year-to-date. The decrease in year-to-date earnings wasfor the first quarter of 2020, driven by reduced natural gas margins primarily due to unfavorable weather as well as lower electric margin, which reflects the unfavorable weather experienced in North and South Dakota. NSP-Minnesota also recognized increased interest and higher O&M and depreciation, partially offset by the timing of gas rates in 2018lower O&M and higher gas sales.income taxes.
NSP-MinnesotaSPS — Earnings decreased $0.02 per share for the first quarter of 2020, reflecting lower electric margin primarily due to a 2019 NMPRC revised order eliminating a $10 million retroactive refund of tax reform benefits. SPS also recognized additional depreciation and less AFUDC, partially offset by lower income taxes.
NSP-Wisconsin — Earnings increased $0.01 per share for the secondfirst quarter of 20192020, driven by reduced O&M and $0.01 per share year-to-date.

Statement of Income Analysis
The following summarizes the items that affected the individual revenue and expense items reported in the consolidated statements of income.
Estimated Impact of Temperature Changes on Regulated Earnings — Unusually—Unusually hot summers or cold winters increase electric and natural gas sales, while mild weather reduces electric and natural gas sales. The estimated impact of weather on earnings is based on the number of customers, temperature variances, and the amount of natural gas or electricity historically used per degree of temperature. Weathertemperature and excludes any incremental related operating expenses that could result due to storm activity or vegetation management requirements. As a result, weather deviations from normal levels can affect Xcel Energy’s financial performance.


Degree-day or Temperature-Humidity Index (THI)THI data is used to estimate amounts of energy required to maintain comfortable indoor temperature levels based on each day’s average temperature and humidity. Heating degree-days (HDD)HDD is the measure of the variation in the weather based on the extent to which the average daily temperature falls below 65° Fahrenheit. Cooling degree-days (CDD)CDD is the measure of the variation in the weather based on the extent to which the average daily temperature rises above 65° Fahrenheit. Each degree of temperature above 65° Fahrenheit is counted as one CDD, and each degree of temperature below 65° Fahrenheit is counted as one HDD. In Xcel Energy’s more humid service territories, a THI is used in place of CDD, which adds a humidity factor to CDD. HDD, CDD and THI are most likely to impact the usage of Xcel Energy’s residential and commercial customers. Industrial customers are less sensitive to weather.
Normal weather conditions are defined as either the 20-year10, 20 or 30-year average of actual historical weather conditions. The historical period of time used in the calculation of normal weather differs by jurisdiction, based on regulatory practice. To calculate the impact of weather on demand, a demand factor is applied to the weather impact on sales. Extreme weather variations, windchill and cloud cover may not be reflected in weather-normalized estimates.
There was no impact on sales for the first quarter of 2020 due to THI or CDD. Percentage increase (decrease)change in normal and actual HDD, CDD and THI:HDD:

Electric Margin
Electric revenues and fuel and purchased power expenses are impacted by fluctuations in the price of natural gas, coal and uranium used in the generation of electricity. However, these price fluctuations have minimal impact on electric margin due to fuel recovery mechanisms that recover fuel expenses.
In addition, electric customers receive a credit for PTCs generated in a particular period.

Regulation
FERC and State Regulation
Public Utility Regulation
The FERC and various state and local regulatory commissions regulate Xcel Energy Inc.’s utility subsidiaries and WGI. The electric and natural gas rates charged to customers of Xcel Energy Inc.’s utility subsidiaries and WGI are approved by the FERC or the regulatory commissions in the states in which they operate.
The rates are designed to recover plant investment, operating costs and an allowed return on investment. Xcel Energy Inc.’s utility subsidiaries request changes in rates for utility services through filings with governing commissions.
Changes in operating costs can affect Xcel Energy’s financial results, depending on the timing of rate case filings and implementation of final rates. Other factors affecting rate filings are new investments, sales, conservation and DSM efforts, and the cost of capital. In addition, the regulatory commissions authorize the ROE, capital structure and depreciation rates in rate proceedings. Decisions by these regulators can significantly impact Xcel Energy’s results of operations.
Recently Filed Regulatory Proceedings
NSP-Wisconsin Rate Case Settlement In May 2019, NSP-Wisconsin filed an application with the PSCW seeking approval of a rate case settlement with various intervenors for 2020-2021.
For NSP-Wisconsin’s electric utility, the settlement agreement results in no change to base rates through Dec. 31, 2021. For the natural gas utility, there would be a $3.2 million (4.6%) decrease to base rates, effective Jan. 1, 2020, and no additional changes to base rates through Dec. 31, 2021.
Key elements of the settlement include:
Electric:
Allowed ROE of 10.0%;
Allowed equity ratio of 52.5%;
Retain expected fuel cost savings from new wind farms for the NSP System;
Allow deferral of pension settlement costs, if any, for 2019-2021;
Utilize a portion of tax reform benefits to offset revenue deficiency;
Allow deferral of certain large customer non-fuel cost of service impacts and bad debt expense in 2019-2021; and
Apply an earnings sharing mechanism for 2020 and 2021. The mechanism would return to customers 50% of earnings between 10.25% and 10.75% ROE and 100% of earnings equal to or in excess of 10.75% ROE.
Natural Gas:
Utilize tax reform benefits of $22.3 million to offset a portion of the regulatory asset for remediation of the MGP site in Ashland, WI.
On Aug. 1, 2019, the PSCW verbally approved the settlement agreement as filed with one minor modification, to remove the deferral of pension settlement accounting costs for 2021. NSP-Wisconsin anticipates a final written order in September 2019.
PSCo Colorado 2019 Electric Rate Case — In May 2019, PSCo filed a request with the CPUC seeking a net rate increase of approximately $158 million, or 5.7%. The filing also requests the transfer of $249 million of rider revenue to base rates, which will not impact overall customer bills as the revenue is currently being recovered through various riders. The request is based on a ROE of 10.35%, an equity ratio of 56.46%, a historic test year ended Dec. 31, 2018 (adjusted for 2019 capital investment) and incorporates the full impact of tax reform. PSCo has requested rates effective Jan. 1, 2020.

SPS New Mexico 2019 Electric Rate Case — In July 2019, SPS filed an electric rate case with the NMPRC seeking an increase in retail electric base rates of approximately $51 million. The rate request is based on a ROE of 10.35%, a 54.77% equity ratio, a rate base of approximately $1.3 billion and a historic test year with rate base additions through Aug. 31, 2019. SPS anticipates final rates will go into effect in the second or third quarter of 2020.
SPS' net revenue increase to New Mexico consumers is expected to be approximately $26 million, or 5.7%, due to fuel cost reductions and PTCs attributable to wind energy provided by the Hale Wind Project. PTCs are being credited to customers through the fuel clause.

NSP-Minnesota MEC Acquisition — In November 2018, NSP-Minnesota reached an agreement with Southern Power Company to purchase the 760 MW natural gas CC facility for approximately $650 million. NSP-Minnesota currently purchases the energy and capacity of this facility through PPAs. The acquisition is projected to provide net customer savings of approximately $50 million to $150 million over the life of the plant.
In May 2019, NSP-Minnesota entered into a partial settlement agreement with several environmental organizations and the LIUNA. Under the terms of the agreement, the settling parties supported the MEC acquisition and NSP-Minnesota agreed to include (in its preferred plan in the Minnesota resource plan filing) early retirement of the Sherco 3 and King coal plants, as well as 3,000 MW of solar additions before 2030.
In May 2019, the FERC approved the purchase. In July 2019, the DOC and OAG recommended the MPUC deny approval of the Mankato acquisition. The DOC and OAG also recommended that if the MPUC were to approve the transaction, that the Commission disallow all or a portion of the acquisitions adjustment as well as require certain other customer protections. The MPUC is expected to hold hearings and make a decision in the third quarter.

NSP-Minnesota Minnesota Resource Plan In July 2019, NSP-Minnesota filed its Minnesota resource plan, which runs through 2034. The preferred plan would result in an 80% carbon reduction by 2030 and puts NSP on a path to achieving its vision of being 100% carbon-free by 2050. The preferred plan includes the following:
Extends the life of the Monticello nuclear plant from 2030 to 2040;
Continues to run the Prairie Island nuclear plant through current end of life (2033 and 2034);
Includes the MEC acquisition and construction of the Sherco CC natural gas plant;
Includes the early retirement of the King coal plant (511 MW) in 2028 and the Sherco 3 coal plant (517 MW) in 2030;
Adds approximately 1,700 MW of firm peaking (CT, pumped hydro, battery storage, DR, etc.);
Adds approximately 1,200 MW of wind replacement; and
Adds approximately 4,000 MW of solar.
Intervening parties will provide recommendations and comments on the resource plan. The MPUC is anticipated to make a final decision on the resource plan in late 2020 or the first half of 2021.
NSP-Minnesota Jeffers Wind and CommunityWind North Repowering Acquisition In December 2018, NSP-Minnesota filed a request with the MPUC seeking approval to acquire the Jeffers and Community Wind North wind facilities in western Minnesota from Longroad Energy. The wind farms, currently contracted under PPAs with NSP-Minnesota, will have approximately 70 MW of capacity after being repowered. The repowering and acquisition are expected to be complete by December 2020 and qualify for the 100% PTC benefit. The $135 million asset acquisition is projected to provide customer savings of approximately $7 million over the life of the facilities, compared to the amended PPAs. The FERC approved the acquisition in July 2019.
The DOC filed initial comments in support of NSP-Minnesota continuing to contract for the assets under the amended PPAs, but not the acquisition, pending additional information, including a purchase and sales agreement. NSP-Minnesota subsequently filed additional information, including an executed purchase and sale agreement, to address DOC concerns. Reply comments are due in August, with an MPUC decision expected in the second half of 2019.

Minnesota State ROFR Statute Complaint — In September 2017, LSP Transmission filed a complaint in the Minnesota District Court against the Minnesota Attorney General, MPUC and DOC. The complaint was in response to MISO assigning NSP-Minnesota and ITC Midwest, LLC to jointly own a new Mankato-Winnebago 345 KV transmission line (estimatedfrom Mankato to Winnebago, Minnesota. The project was estimated to cost $108 million and projected to be in-service by the end of $108 million),2021. It was assigned to NSP-Minnesota and ITC Midwest as the incumbent utilities, consistent with a Minnesota state ROFR statute.
The complaint challenged the constitutionality of the state ROFR statute and is seeking declaratory judgment that the statute violates the Commerce Clause of the U.S. Constitution and should not be enforced.
The Minnesota state agencies and NSP-Minnesota filed motions to dismiss. In June 2018, the Minnesota District Court granted the defendants’ motions
to dismiss with prejudice. LSP Transmission filed an appeal in July 2018. In September 2019, the estimate was updated to approximately $140 million, due to various changes in build plans.

Rate CaseElectric$51July 2019PendingIn July 2019, SPS filed an electric rate case with the NMPRC seeking an increase in retail electric base rates of approximately $51 million. The rate request is based on an ROE of 10.35%, an equity ratio of 54.77%, a rate base of approximately $1.3 billion and a historic test year with rate base additions through Aug. 31, 2019. In December 2019, SPS revised its base rate increase request to approximately $47 million, based on an ROE of 10.10% and updated information. The request also included an increase of $14.6 million for accelerated depreciation including the early retirement of the Tolk coal plant in 2032.
In January 2020, SPS and various parties filed an uncontested comprehensive stipulation. The stipulation includes a base rate revenue increase of $31 million, an ROE of 9.45% and an equity ratio of 54.77%. The stipulation also includes an acceleration of depreciation on the Tolk coal plant to reflect early retirement in 2037, which results in a total increase in depreciation expense of $8 million. The parties to the stipulation agreed not to oppose the full application of depreciation rates associated with the 2032 retirement date in SPS’ next base rate case. A NMPRC decision is expected later in the year. SPS anticipates final rates will go into effect in the second or third quarter of 2020.

Texas State (ROFR) Request for Declaratory OrderROFR Litigation — In 2017, SPS and SPP filed a joint petition with the PUCT for a declaratory order regarding SPS’ ROFR. SPS contended that Texas law grants an incumbent electric utility the ROFR to construct new transmission facilities located in the utility’s service area. The PUCT subsequently issued an order finding that SPS does not possess an exclusive right to construct and operate transmission facilities. SPS filed an appeal in the fourth quarter of 2018. Subsequent to that appeal, in May 2019, the Texas legislature passed and the Governor signed into law Senate Bill 1938, thus making SPS’ appeal moot. A motion is pending at the Court of Appeals to dismiss the appeal for mootness. Senate Bill 1938which grants incumbent utilities a ROFR to build transmission infrastructure when the transmissionit directly interconnects to the utility’s existing facility. In June 2019, a complaint was filed in the United States District Court for the Western District of Texas claiming the new ROFR law set forth in Senate bill 1938 to be unconstitutional. SPS expectsThe Texas Attorney General has made a motion to intervene in this litigation in support ofdismiss the PUCT andfederal court complaint.

Texas Fuel ReconciliationRefundFuel and purchased power costs are recoverable in Texas through a fixed fuel factor, which is part of SPS’ rates. The PUCT rule requires refunding or surcharging of under and over-recovered amounts, including interest, when they exceed 4% of the utility’s annual fuel costs on a rolling 12-month basis, as allowed by the PUCT, if this condition is expected to continue.
Under the fuel cost recovery rules, SPS’ 2019 total fuel and purchased power costs were over-collected by approximately $39 million, including interest. In December 2018,February 2020, SPS filed an application towith the PUCT for reconciliationrequesting to provide a net refund of fuel costs for the period Jan. 1, 2016, through June 30, 2018, where it will be determined whether all fuel costs incurred during the period were eligible for recovery. Parties in the proceeding have asserted that certain Texas retail fuel costs of up$39 million to approximately $4 million, should not be foundcustomers to be reasonable or prudent, in particular regarding two purchase power agreements for solar power.

At June 30,March 31, 2020, a 10% increase in market prices for commodity trading contracts would increase pre-tax income from continuing operations by approximately $9 million, whereas a 10% decrease would decrease pre-tax income from continuing operations by approximately $9 million. At March 31, 2019, a 10% increase in market prices for commodity trading contracts would decrease pretaxincrease pre-tax income from continuing operations by approximately $2$8 million, whereas a 10% decrease would increase pretaxdecrease pre-tax income from continuing operations by approximately $2 million. At June 30, 2018, a 10% increase in market prices for commodity trading contracts would decrease pretax income from continuing operations by an immaterial amount, whereas a 10% decrease would increase pretax income from continuing operations by approximately $1$8 million.
Xcel Energy Inc.’sThe utility subsidiaries’ wholesale and commodity trading operations measure the outstanding risk exposure to price changes on transactions, contracts and obligations that have been entered into, but not closed, using an industry standard methodology known as Value at Risk (VaR). VaR expresses the potential change in fair value on the outstanding transactions, contracts and obligations over a particular period of time under normal market conditions.
The VaRs for the NSP-Minnesota and PSCo commodity trading operations, excluding both non-derivative transactions and derivative transactions designated as normal purchase, normal sales, calculated on a consolidated basis using a Monte Carlo simulation with a 95% confidence level and a one-day holding period, were as follows:

In November 2018, management temporarily increased the VaR limit to accommodate a 10-year transaction. NSP-Minnesota has been systematically hedging the transaction and the consolidated VaR returned below $3 million in early January 2019.
Nuclear Fuel Supply — NSP-Minnesota is scheduled to take delivery ofhas contracted for approximately 49% of its remaining 2019 and approximately 50%51% of its 2020 enriched nuclear material requirements from sources that could be impacted by events in Ukraine and extended sanctions against entities doing business with Iran. Those sanctions may impact the supply of enriched nuclear material supplied from Russia.  Long-term, through 2024,2030, NSP-Minnesota is scheduled to take delivery of approximately 35%30% of its average enriched nuclear material requirements from these sources. Alternate potential sources provide the flexibility to manage NSP-Minnesota’s nuclear fuel supply. NSP-Minnesota periodically assesses if further actions are required to assure a secure supply of enriched nuclear material.
Disruptions in third party nuclear fuel supply contracts due to bankruptcies or change of contract assignments have not materially impacted NSP-Minnesota’s operational or financial performance.
Interest Rate Risk — Xcel Energy is subject to the risk of fluctuating interest rates in the normal course of business. Xcel Energy’srate risk. Our risk management policy allows interest rate risk to be managed through the use of fixed rate debt, floating rate debt and interest rate derivatives such as swaps, caps, collars and put or call options.
At June 30,March 31, 2020 and 2019, and 2018, a 100-basis-point change in the benchmark rate on Xcel Energy’s variable rate debt would impact pretaxpre-tax interest expense annually by approximately $17$21 million and $8$13 million, respectively.
See Note 8 to the consolidated financial statements for a discussion of Xcel Energy Inc. and its subsidiaries’ interest rate derivatives.
NSP-Minnesota also maintains a nuclear decommissioning fund, as required by the NRC. The nuclear decommissioning fund is subject to interest rate risk and equity price risk. At June 30, 2019, theThe fund wasis invested in a diversified portfolio of cash equivalents, debt securities, equity securities, and other investments.

Fluctuations in equity prices or interest rates affecting the nuclear decommissioning fund do not have a direct impact on earnings.earnings due to the application of regulatory accounting.
Changes in discount rates and expected return on plan assets impact the value of pension and postretirement plan assets and/or benefit costs.
Credit Risk Xcel Energy Inc. and its subsidiaries areis also exposed to credit risk. Credit risk relates to the risk of loss resulting from counterparties’ nonperformance on their contractual obligations. Xcel Energy Inc. and its subsidiaries maintainThe Company maintains credit policies intended to minimize overall credit risk and actively monitor these policies to reflect changes and scope of operations.
At June 30,March 31, 2020, a 10% increase in commodity prices would have resulted in an increase in credit exposure of $21 million, while a decrease in prices of 10% would have resulted in an immaterial decrease in credit exposure. At March 31, 2019, a 10% increase in commodity prices would have resulted in an increase in credit exposure of $14$29 million, while a decrease in prices of 10% would have resulted in an increase in credit exposure of $16 million.

Fair Value Measurements
FAIR VALUE MEASUREMENTS
Xcel Energy follows accountinguses derivative contracts such as futures, forwards, interest rate swaps, options and disclosure guidance onFTRs to manage commodity price and interest rate risk. Derivative contracts, with the exception of those designated as normal purchase-normal sale contracts, are reported at fair value.


The Company’s investments held in the nuclear decommissioning fund, rabbi trusts, pension and other postretirement funds are also subject to fair value measurements that contains a hierarchy for inputs used in measuring fair value and requires disclosure of the observability of the inputs used in these measurements. accounting.
See Note 8 to the consolidated financial statements for further discussion of the fair value hierarchy and the amounts of assets and liabilities measured at fair value that have been assigned to Level 3.
Commodity Derivatives — Xcel Energy continuously monitors the creditworthiness of the counterparties to its commodity derivative contracts and assesses each counterparty’s ability to perform on the transactions set forth in the contracts. Given this assessment and the typically short duration of these contracts, thetransactions. The impact of discounting commodity derivative assets for counterparty credit risk was not material to the fair value of commodity derivative assets at June 30, 2019. March 31, 2020.
Adjustments to fair value for credit risk of commodity trading instruments are recorded in electric revenues. Credit risk adjustments for other commodity derivative instruments are deferred as other comprehensive income or deferred as regulatory assets and liabilities. Classification as a regulatory asset or liability is based on commission approved regulatory recovery mechanisms. Xcel Energy also assesses the impact of its own credit risk when determining the fair value of commodity derivative liabilities. The impact of discounting commodity derivative liabilities for credit risk was immaterial to the fair value of commodity derivative liabilities at June 30, 2019.March 31, 2020.

Earnings Guidance and Long-Term EPS and Dividend Growth Rate Objectives
Xcel Energy 20192020 Earnings Guidance — Xcel Energy‘s 2019 GAAP and ongoingEnergy reaffirms 2020 EPS earnings guidance is a range of $2.55$2.73 to $2.65$2.83 per share.share (a) (b), which assumes the implementation of contingency plans will be sufficient to offset the negative impacts of COVID-19 under the base case scenario. However, these contingency plans would not be sufficient to offset the negative impacts of COVID-19 under the severe scenario, which would likely result in earnings below the guidance range.
Key assumptions:assumptions as compared with 2019 levels unless noted:
Constructive outcomes in all rate case and regulatory proceedings.
Normal weather patterns for the remainder of the year.
Weather-normalized retail electric sales are projected to be relatively consistent with 2018 levels.decline ~4%, under the base case scenario.
Weather-normalized retail firm natural gas sales are projected to be within a range of 2.0% to 3.0% over 2018 levels.decline ~1%, under the base case scenario.
Capital rider revenue is projected to increase $115$45 million to $125$55 million (net of PTCs) over 2018 levels.. PTCs are flowed backcredited to customers, through capital riders and reductions to electric margin.
Purchase capacity costs are expected to decline $25 million to $30 million compared with 2018 levels.
O&M expenses are projected to decreasedecline approximately 2.0% from 2018 levels.4% to 5% under the base case scenario.
Depreciation expense is projected to increase approximately $135$160 million to $145 million over 2018 levels. Depreciation expense includes $34 million for the amortization of a prepaid pension asset at PSCo, which is tax reform related and will not impact earnings. A significant portion of the change in depreciation expense reflects an adjustment for the new lease accounting standard, which reclassifies certain expense from electric fuel and purchase power to depreciation and amortization with no impact on earnings.$170 million.
Property taxes are projected to increase approximately $15$35 million to $25 million over 2018 levels.$45 million.
Interest expense (net of AFUDC - debt) is projected to increase $80$60 million to $90 million over 2018 levels.$70 million.
AFUDC - equity is projected to decreaseincrease approximately $20$25 million to $30 million from 2018 levels.$35 million.
The ETR is projected to be approximately 80%. to 10%. The ETR reflects benefits of PTCs which are flowed backcredited to customers through electric margin and will not have a material impact on net income.
(a)  
Ongoing earnings is calculated using net income and adjusting for certain nonrecurring or infrequent items that are, in management’s view, not reflective of ongoing operations. Ongoing earnings could differ from those prepared in accordance with GAAP for unplanned and/or unknown adjustments. Xcel Energy is unable to forecast if any of these items will occur or provide a quantitative reconciliation of the guidance for ongoing EPS to corresponding GAAP diluted EPS.

The global outbreak of COVID-19 is currently impacting countries, communities, supply chains and markets. The ultimate severity of this event is uncertain and could have a material impact on our liquidity, financial condition, or results of operations.
Long-Term EPS and Dividend Growth Rate Objectives Xcel Energy expects to deliver an attractive total return to our shareholders through a combination of earnings growth and dividend yield, based on the following long-term objectives:
Deliver long-term annual EPS growth of 55% to 7% based off of a 20182019 base of $2.43$2.60 per share, which represents the mid-point of the original 20182019 guidance range of $2.37$2.55 to $2.47$2.65 per share;
Deliver annual dividend increases of 55% to 7%;
Target a dividend payout ratio of 6060% to 70%; and
Maintain senior secured debt credit ratings in the A range.


COVID-19
The global outbreak of the COVID-19 pandemic has adversely impacted economic conditions worldwide. Efforts to control the spread of COVID-19 have led to shutdowns or curtailments of various industries, disrupting supply chains and markets. Beginning in mid-March, wide-spread government mandates (e.g., shelter-in-place) or other initiatives impacted our service territories. COVID-19 did not significantly impact first quarter 2020 results, but could have a material impact on our financial results in the future.
An overview of certain risk considerations or areas which have or could significantly impact us, is as follows:
Sales— In the first quarter of 2020, Xcel Energy experienced a decline in weather and leap year adjusted sales. The decline in sales was primarily due to pandemic related mandates implemented in March 2020 involving the temporary closure of non-essential businesses and state directives for individuals to stay-at-home. We experienced a substantive decline in April sales and expect that our future sales will be impacted due to stay-at-home and closure provisions in place and the impact of COVID-19 on the economy and its ultimate recovery.
Xcel Energy has decoupling and sales true-up mechanisms in Minnesota (all electric classes) and Colorado (residential and non-demand SC&I electric classes), which mitigate the impact of changes to sales levels as compared to a base line.
The following scenarios outline the potential impact of the pandemic on electric and natural gas sales and EPS, based on various assumptions of the duration of the stay-at-home provisions and economic recovery:
Mild Scenario (severe impact through May with a V-shaped economic recovery), resulting in the following change in electric sales for 2020: an increase of approximately 1% in residential; a decline of approximately 4% in C&I; and a decline in total retail electric sales of approximately 2%. This sales decline would reduce EPS by approximately $0.11.
Base Case Scenario (severe impact through the second quarter with slower U-shaped recovery with lingering effects throughout 2020), resulting in the following change in electric sales for 2020: an increase of approximately 1% in residential; a decline of approximately 6% in C&I; and a decline in total retail electric sales of approximately 4%. This sales decline would reduce EPS by approximately $0.17.
Severe Scenario (severe impact through the third quarter followed by protracted challenged L-shaped recovery), resulting in the following change in electric sales for 2020: an increase of approximately 1% in residential; a decline of approximately 12% in C&I; and a decline in total retail electric sales of approximately 8%. This sales decline would reduce EPS by approximately $0.37.
The mild, base case and severe scenarios include a decrease in natural gas sales of 0%, 1% and 2%, respectively.
Potential impacts due to other items could have negative EPS impact of $0.02 to $0.05, assuming constructive regulatory treatment.
Bad Debt— In March 2020, Xcel Energy announced it would not disconnect residential customers’ electric or natural gas service during the virus outbreak. Certain states have issued additional limitations on charging late fees and extended protection to other customer classes. Bad debt expense could significantly increase due to regulatory orders, pandemic related economic impacts and customers hardship. However, several of our commissions are allowing the deferral of incremental COVID-19 related expense, including bad debt expense as discussed further under Regulatory.
Regulatory— Xcel Energy has received orders in Wisconsin, Texas and Michigan, allowing regulatory deferral of incremental COVID-19 costs as a regulatory asset subject to future determination of amount and timing of recovery. Costs include, but are not limited to, suspension of disconnections, waived late fees and other costs and/or foregone revenues. In addition, the Company has filed requests in Colorado, Minnesota, North Dakota, New Mexico and South Dakota to record a regulatory asset and defer all incremental expenses related to the pandemic.
We will continue to monitor these costs and assess whether the actions of the regulator provide the evidence necessary to defer amounts as regulatory assets. Xcel Energy serves the majority of its wholesale customers under formula transmission and production rates which true-up rates to actual costs to serve.
Contingency Plan— We are implementing contingency plans to reduce costs to offset the negative impact of COVID-19. Actions include reductions of employee expenses, consulting, variable compensation, delays of certain work activities, attrition and implementation of a hiring freeze. Based on these actions, our base case assumption is that 2020 O&M expenses will decline 4% to 5% compared with 2019. The ultimate level of O&M expenses will be dependent on actual sales levels.
In addition, we have received orders allowing the deferral of incremental pandemic related expenses in Texas, Wisconsin and Michigan.  We are seeking regulatory authority to defer incremental expense in Minnesota, Colorado and other states.
We believe we can deliver earnings within our 2020 guidance range based on implementing contingency plans to offset the impact of the pandemic on sales and expense levels under the base case scenario. However, our contingency plans may not be able to offset the negative impact of COVID-19 under a severe scenario.
Supply Chain and Capital Expenditures— Xcel Energy’s ability to meet customer energy requirements, respond to storm-related disruptions and maintain our capital expenditure program are dependent on maintaining an efficient supply chain. During the first quarter of 2020, Xcel Energy did not experience any material supply chain, contractor or employee disruptions that prevented us from performing maintenance or construction activity. As a result, we have not significantly adjusted our 2020 capital expenditure plan.
However, the situation is fluid and in April we were informed of supply chain disruptions, which will likely result in delays in the completion of two of our wind farms into 2021. We are working through these challenges to try to complete the projects this year, however, we believe these wind farms would meet the IRS continuous efforts criteria and qualify for 100% PTC benefit even if completed in 2021.
Pension— The funded status of the Xcel Energy pension plans was approximately 90% in January 2020.  The funded status of the pension plan is estimated to be in the low 80% range, based on market conditions as of early May 2020.
Our disciplined pension plan management practices include maintaining a well-diversified growth portfolio across a diverse set of asset classes and an allocation to interest rate hedging instruments. Xcel Energy does not expect any material changes to its pension funding requirement at this time. In addition, Xcel Energy has pension trackers in Colorado and Texas, which allow us to defer amounts that are above or below a baseline.


Liquidity — Xcel Energy has taken steps to enhance its liquidity and believes it has more than adequate liquidity.
As a result of these actions, Xcel Energy currently has $3.1 billion of available liquidity. In addition, there are other items that will enhance liquidity.
Xcel Energy has an outstanding forward equity agreement in connection with a $743 million public offering of 11.8 million shares. These shares have not been issued and we expect to settle this equity forward later in 2020.
The MEC sale will result in approximately $650 million of additional funds, after our previously-announced planned corporate giving, that can be used for general corporate purposes and enhanced liquidity.
Xcel Energy continues to have access to the capital markets on favorable terms.
Customer Service & Reliability — Xcel Energy remains committed to continuing to safely deliver reliable services to our customers as families and communities face the COVID-19 pandemic. We have exercised our business continuity plans to safely serve our customers, protect our employees and ensure critical positions remain staffed.
Key actions include:
Executing work-from-home practices for employees who can do their work remotely;
Enhancing cleaning practices within our facilities;
Providing proper personal protective equipment and following CDC and state guidelines;
Conducting employee temperature checks;
Changing work practices to promote social distancing;
Splitting crews and staggering work times;
Limiting employee entry into customer homes to emergency situations only; and
Reminding customers of increased risks of scam activity.
Employees — The health and safety of our workforce is one of our core values, and we have taken several actions that reflect that during this pandemic:
Continued pay for employees who have been quarantined;
Expanded medical plan coverage for employees and their families to include 100% of COVID-19 medical costs;
Offered up to an additional 80 hours of paid time off to employees for pandemic related illness;
Expanded eligibility for our paid time off donation program to employees who have or are caring for a family member who has been diagnosed with the virus;
Offered new anxiety and stress management tools, in addition to our existing Employee Assistance Program; and
Provided resources and educational materials to support employees adjusting to distance learning with their children.
Communities — Xcel Energy is committed to the communities in which we operate. Early actions include the following:
Plan to donate approximately $20 million in corporate giving, including COVID-19 relief in 2020.  Along with the Xcel Energy Foundation, we have already donated approximately $1.5 million to support pandemic relief efforts across our eight-state footprint and implemented a virtual volunteering program;
Donated over 300,000 masks to hospitals in the communities we serve; and launched a special $300,000 COVID-19 two-to-one matching campaign, which provides a match for employee donations to impacted non-profit organizations, in addition to our standard employee matching gift programs; and
Submitted a proposal to reduce our approved 2020 Fuel Forecast by $25 million to provide immediate relief to our Minnesota customers during the pandemic and resulting economic downturn, which will be implemented across the three summer months equally.

Part II — OTHER INFORMATION
Item 1Legal Proceedings
ITEM 1 — LEGAL PROCEEDINGS
Xcel Energy is involved in various litigation matters that are being defended and handled in the ordinary course of business. The assessment of whether a loss is probable or is a reasonable possibility, and whether athe loss or a range of loss is estimable, often involves a series of complex judgments regardingabout future events. Management maintains accruals for losses that are probable of being incurred and subject to reasonable estimation. Management may beis sometimes unable to estimate an amount or range of a reasonably possible loss in certain situations, including but not limited to when (1) the damages sought are indeterminate, (2) the proceedings are in the early stages, or (3) the matters involve novel or unsettled legal theories.
In such cases, there is considerable uncertainty regarding the timing or ultimate resolution of such matters, including a possible eventual loss. For current proceedings not specifically reported herein, management does not anticipate that the ultimate liabilities, if any, would have a material effect on Xcel Energy’s financial statements. Unless otherwise required by GAAP, legal fees are expensed as incurred.
See Note 10 to the consolidated financial statements and Part I Item 2 for further information.

Nor can we predict the impact of the virus on the health of our employees, our supply chain or our ability to recover higher costs associated with managing through the pandemic.
