XCEL ENERGY INC. AND SUBSIDIARIES

Notes to Consolidated Financial Statements (UNAUDITED)

In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments necessary to present fairly, in accordance with accounting principles generally accepted in the United States of America (GAAP), the financial position of Xcel Energy Inc. and its subsidiaries as of June 30, ~~2016~~2017 and Dec. 31, ~~2015;~~2016; the results of its operations, including the components of net income and comprehensive income, and changes in stockholders’ equity for the three and six months ended June 30, ~~2016~~2017 and ~~2015;~~2016; and its cash flows for the six months ended June 30, ~~2016~~2017 and ~~2015.~~2016. All adjustments are of a normal, recurring nature, except as otherwise disclosed. Management has also evaluated the impact of events occurring after June 30, ~~2016~~2017 up to the date of issuance of these consolidated financial statements. These statements contain all necessary adjustments and disclosures resulting from that evaluation. The Dec. 31, ~~2015~~2016 balance sheet information has been derived from the audited ~~2015~~2016 consolidated financial statements included in the Xcel Energy Inc. Annual Report on Form 10-K for the year ended Dec. 31, ~~2015.~~2016. These notes to the consolidated financial statements have been prepared pursuant to the rules and regulations of the SEC for Quarterly Reports on Form 10-Q. Certain information and note disclosures normally included in financial statements prepared in accordance with GAAP on an annual basis have been condensed or omitted pursuant to such rules and regulations. For further information, refer to the consolidated financial statements and notes thereto, included in the Xcel Energy Inc. Annual Report on Form 10-K for the year ended Dec. 31, ~~2015,~~2016, filed with the SEC on Feb. ~~19, 2016.~~24, 2017. Due to the seasonality of Xcel Energy’s electric and natural gas sales, interim results are not necessarily an appropriate base from which to project annual results.


1.	Summary of Significant Accounting Policies

The significant accounting policies set forth in Note 1 to the consolidated financial statements in the Xcel Energy Inc. Annual Report on Form 10-K for the year ended Dec. 31, ~~2015,~~2016, appropriately represent, in all material respects, the current status of accounting policies and are incorporated herein by reference.


2.	Accounting Pronouncements

Recently Issued

Revenue Recognition — In May 2014, the Financial Accounting Standards Board (FASB) issued Revenue from Contracts with Customers, Topic 606 (Accounting Standards Update (ASU) No. 2014-09), which provides a new framework for the recognition of ~~revenue, with the objective that recognized revenues properly reflect amounts an entity is entitled to receive~~revenue. Xcel Energy expects its adoption will result in ~~exchange for goods and services. The new guidance also includes additional disclosure requirements~~increased disclosures regarding revenue, cash flows and obligations related to arrangements with customers, as well as separate presentation of alternative revenue programs. Xcel Energy has not yet fully determined the impacts of adoption for several aspects of the standard, including a determination whether and how much an evaluation of the collectability of regulated electric and gas revenues will impact the amounts of revenue recognized upon delivery. Xcel Energy currently expects to implement the standard on a modified retrospective basis, which requires application to contracts with ~~customers. The guidance is~~customers effective ~~for interim and annual reporting periods beginning after Dec. 15, 2017. Xcel Energy is currently evaluating~~Jan. 1, 2018, with the ~~impact of adopting ASU 2014-09 on its consolidated financial statements.~~

~~Presentation of Deferred Taxes —~~ ~~In November 2015, the FASB issued~~ ~~Balance Sheet Classification of Deferred Taxes, Topic 740 (ASU No 2015-17)~~, which eliminates the requirement to present deferred tax assets and liabilities as current and noncurrent on the balance sheet based on the classification of the related asset or liability, and instead requires classification of all deferred tax assets and liabilities as noncurrent. This guidance will be effective for interim and annual reporting periods beginning after Dec. 15, 2016, and early adoption is permitted. Other than the prescribed classification of all deferred tax assets and liabilities as noncurrent, Xcel Energy does not expect the implementation of ASU 2015-17 to have a materialcumulative impact on ~~its consolidated financial statements.~~contracts not yet completed as of Dec. 31, 2017 recognized as an adjustment to the opening balance of retained earnings.

Classification and Measurement of Financial Instruments — In January 2016, the FASB issued Recognition and Measurement of Financial Assets and Financial Liabilities, Subtopic 825-10 (ASU No. 2016-01), which ~~among other changes in accounting~~eliminates the available-for-sale classification for marketable equity securities and ~~disclosure requirements,~~also replaces the cost method of accounting for non-marketable equity securities with a model for recognizing impairments and observable price ~~changes, and also eliminates the available-for-sale classification for marketable equity securities.~~changes. Under the new ~~guidance,~~standard, other than when the consolidation or equity method of accounting is utilized, changes in the fair value of equity securities are to be recognized in earnings. This guidance will be effective for interim and annual reporting periods beginning after Dec. 15, 2017. Xcel Energy isexpects that as a result of application of accounting principles for rate regulated entities, changes in the fair value of the securities in the nuclear decommissioning fund, currently ~~evaluating~~classified as available-for-sale, will continue to be deferred to a regulatory asset, and that the ~~impact~~overall impacts of ~~adopting ASU 2016-01 on its consolidated financial statements.~~the Jan. 1, 2018 adoption will not be material.

~~Table of Contents~~

Leases — InIn February 2016, the FASB issued Leases, Topic 842 (ASU No. 2016-02), which for lessees requires balance sheet recognition of right-of-use assets and lease liabilities for ~~all~~most leases. Additionally, for leases that qualify as finance leases, the guidance requires expense recognition consisting of amortization of the right-of-use asset as well as interest on the related lease liability using the effective interest method. This guidance will be effective for interim and annual reporting periods beginning after Dec. 15, ~~2018, and early~~2018. Xcel Energy has not yet fully determined the impacts of implementation. However, adoption is ~~permitted.~~expected to occur on Jan. 1, 2019 utilizing the practical expedients provided by the standard. As such, agreements entered prior to Jan. 1, 2017 that are currently considered leases are expected to be recognized on the consolidated balance sheet, including contracts for use of office space, equipment and natural gas storage assets, as well as certain purchased power agreements (PPAs) for natural gas-fueled generating facilities. Xcel Energy ~~is currently evaluating~~expects that similar agreements entered after Dec. 31, 2016 will generally qualify as leases under the ~~impact~~new standard, but has not yet completed its evaluation of ~~adopting ASU 2016-02 on its consolidated financial statements.~~certain other contracts, including arrangements for the secondary use of assets, such as land easements.

~~Stock Compensation~~Presentation of Net Periodic Benefit Cost — InIn March ~~2016,~~2017, the FASB issued ~~Improvements to Employee Share-Based Payment Accounting,~~Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, Topic ~~718~~715 (ASU ~~2016-09),~~No. 2017-07), which ~~amends existing~~establishes that only the service cost element of pension cost may be presented as a component of operating income in the income statement. Also under the guidance, ~~to simplify several aspects~~only the service cost component of pension cost is eligible for capitalization. Xcel Energy has not yet fully determined the impacts of adoption of the standard, but expects that as a result of application of accounting principles for rate regulated entities, a similar amount of pension cost, including non-service components, will be recognized consistent with the current ratemaking treatment and ~~presentation for share-based payment transactions, including~~that the ~~accounting for income taxes and forfeitures, as well as presentation~~impacts of adoption will be limited to changes in classification of non-service costs in the consolidated statement of ~~cash flows.~~income. This guidance will be effective for interim and annual reporting periods beginning after Dec. 15, ~~2016, and early adoption is permitted. Xcel Energy does not expect the implementation of ASU 2016-09 to have a material impact on its consolidated financial statements.~~2017.

Recently Adopted

~~Consolidation~~Stock Compensation — —I ~~In February 2015,~~n March 2016, the FASB issued ~~Amendments~~Improvements to ~~the Consolidation Analysis,~~Employee Share-Based Payment Accounting, Topic ~~810~~718 (ASU No. ~~2015-02)~~, which reduces the number of consolidation models and amends certain consolidation principles related to variable interest entities. Xcel Energy implemented the guidance on Jan. 1, 2016, and other than the classification of certain real estate investments held within the Nuclear Decommissioning Trust as non-consolidated variable interest entities, the implementation did not have a significant impact on its consolidated financial statements.

~~Presentation of Debt Issuance Costs~~— ~~In April 2015, the FASB issued~~ ~~Simplifying the Presentation of Debt Issuance Costs, Subtopic 835-30 (ASU No. 2015-03)~~, which requires the presentation of debt issuance costs on the balance sheet as a deduction from the carrying amount of the related debt, instead of presentation as an asset. Xcel Energy implemented the new guidance as required on Jan. 1, 2016, and as a result, $94.5 million of deferred debt issuance costs were presented as a deduction from the carrying amount of long-term debt on the consolidated balance sheet as of March 31, 2016, and $91.8 million of such deferred costs were retrospectively reclassified from other non-current assets to long-term debt on the consolidated balance sheet as of Dec. 31, 2015.

~~Fair Value Measurement~~— ~~In May 2015, the FASB issued~~ ~~Disclosures for Investments in Certain Entities that Calculate Net Asset Value per Share (or Its Equivalent), Topic 820 (ASU No. 2015-07)~~2016-09), which ~~eliminates~~simplifies accounting and financial statement presentation for share-based payment transactions. The guidance requires that the ~~requirement~~difference between the tax deduction available upon settlement of share-based equity awards and the tax benefit accumulated over the vesting period be recognized as an adjustment to ~~categorize fair value measurements using a net asset value (NAV) methodology~~income tax expense. Xcel Energy adopted the guidance in 2016, resulting in immaterial 2016 adjustments to income tax expense and changes in classification of cash flows related to tax withholding in the ~~fair value hierarchy. Xcel Energy implemented~~consolidated statements of cash flows for the ~~guidance on Jan. 1,~~years ended Dec. 31, 2016, 2015 and ~~the implementation did not have a material impact on its consolidated financial statements. For related disclosures, see Note 8 to the consolidated financial statements.~~2014.

Except to the extent noted below, Note 6 to the consolidated financial statements included in Xcel Energy Inc.’s Annual Report on Form 10-K for the year ended Dec. 31, ~~2015~~2016 appropriately represents, in all material respects, the current status of other income tax matters, and are incorporated herein by reference.

Federal ~~Tax~~ Loss Carryback Claims — In ~~2012, 2013, 2014 and 2015,~~2012-2015, Xcel Energy identified certain expenses related to 2009, 2010, 2011, 2013, 2014 and 2015 that qualify for an extended carryback beyond the typical two-year carryback period. As a result of a higher tax rate in prior years, Xcel Energy recognized a tax benefit of approximately $5 million in 2015, $17 million in 2014, $12 million in 2013 and $15 million in 2012.

Federal ~~Audit~~Audits — Xcel Energy files a consolidated federal income tax return. The statute of limitations applicable to Xcel Energy’s 2009 through 2013 federal income tax returns, following extensions, expires in December 2017.

State Audits — Xcel Energy files consolidated state tax returns based on income in its major operating jurisdictions of Colorado, Minnesota, Texas, and Wisconsin, and various other state income-based tax returns. As of June 30, ~~2016,~~2017, Xcel Energy’s earliest open tax years that are subject to examination by state taxing authorities in its major operating jurisdictions were as follows:

Unrecognized ~~Tax~~ Benefits — The unrecognized tax benefit balance includes permanent tax positions, which if recognized would affect the annual ~~effective tax rate (ETR).~~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 of cash to the taxing authority to an earlier period.

A reconciliation of the amount of unrecognized tax benefit is as follows:


(Millions of Dollars)	June 30, 2016		Dec. 31, 2015		June 30, 2017		Dec. 31, 2016

It is reasonably possible that Xcel Energy’s amount of unrecognized tax benefits could significantly change in the next 12 months as the IRS Appeals and audit progress, the Minnesota, Texas and ~~Texas~~Wisconsin audits progress, and other state audits resume. As the IRS Appeals and IRS, Minnesota, Texas and ~~Texas~~Wisconsin audits progress, it is reasonably possible that the amount of unrecognized tax benefit could decrease up to approximately ~~$58~~$61 million.

The payable for interest related to unrecognized tax benefits is partially offset by the interest benefit associated with NOL and tax credit carryforwards. ~~The payables~~A reconciliation of the beginning and ending amount of the payable for interest related to unrecognized tax benefits ~~at June 30, 2016 and Dec. 31, 2015 were not material.~~ are as follows:

~~Intervenor Testimony:~~

Annual Automatic Adjustment of Fuel Clause Charges — In ~~June~~ 2016, ~~intervening parties filed direct testimony proposing modifications to NSP-Minnesota’s rate request. The~~the Minnesota Department of Commerce (DOC) subsequently filed revised testimony recommending an increase of approximately $45.6 million in 2016, a step increase of $53.8 million for 2017, and a step decrease of $5.0 million for 2018, based on a recommended ROE of 9.06 percent and an equity ratio of 52.50 percent.

Based on NSP-Minnesota’s interpretation of the DOC’s testimony, certain recommended adjustments of approximately $72.7 million would not be expected to impact earnings, assuming MPUC approval. The following table summarizes NSP-Minnesota’s estimate of the DOC’s recommendations:

The use of certificate of need estimates as a recovery cap, and/or provisionally exclude recovery of amounts in excess of the cap unless the costs are deemed reasonable by the DOC’s nuclear consultant and/or the MPUC.

No recovery of a portion of capital costs associated with Monticello fuel storage Cask 16, representing the amount beyond the originally anticipated project cost, or approximately $15 million. The additional costs incurred were for testing of cask lid welds to demonstrate compliance with Nuclear Regulatory Commission requirements.

~~Settlement Agreement~~

In August 2016, NSP-Minnesota reached a settlement in principal with several of the parties, which resolves all revenue requirement issues in dispute. The terms and conditions of the agreement are still subject to final documentation. The settlement agreement requires the approval of the MPUC.

~~NSP-Minnesota – Gas Utility Infrastructure Costs (GUIC) Rider~~ —In July 2016, the MPUC verbally approved NSP-Minnesota’s request to recover approximately $15 million in natural gas infrastructure costs through the GUIC Rider, based on NSP-Minnesota’s proposed capital structure and a ROE of 9.64 percent, as proposed by the DOC. Recovery was approved for the 15-month period from January 2016 to March 2017.

~~Annual Automatic Adjustment (AAA) of Charges~~ ~~— In June 2016, the DOC~~ recommended the MPUC should hold utilities responsible for incremental costs of replacement power incurred due to unplanned outages at nuclear facilities under certain circumstances. ~~As it pertains~~In May 2017, the MPUC voted to ~~NSP-Minnesota, the DOC’s recommendation could impact~~disallow approximately $4.4 million of replacement ~~power cost recovery~~energy costs for the Prairie Island (PI) nuclear facility outages allocated to the Minnesota jurisdiction ~~during the 2015 AAA fiscal year.

~~Nuclear Project Prudence Investigation~~ — In 2013, NSP-Minnesota completed the Monticello LCM/extended power uprate (EPU) project. The multi-year project extended the life of the facility and increased the capacity from 600 to 671 megawatts (MW) in 2015. The Monticello LCM/EPU project expenditures were approximately $665 million. Total capitalized costs were approximately $748 million, which includes allowance for funds used during construction (AFUDC). In 2008, project expenditures were initially estimated at approximately $320 million, excluding AFUDC.

In 2013, the MPUC initiated an investigation to determine whether the final costs for the Monticello LCM/EPU project were prudent. In March 2015, the MPUC voted to allow for full recovery, including a return, on approximately $415 million of the total plant costs (inclusive of AFUDC), but only allow recovery of the remaining $333 million of costs with no return on this portion of the investment over the remaining life of the plant.

Fuel and purchased power expenses 11.0
Subtotal 28.8
2015 fuel refund ^(a)
(9.5 )
DOE settlement refund (1.9 )
Total electric rate increase $ 17.4


^(a)	In July 2016, the PSCW required NSP-Wisconsin to return the 2015 fuel refund directly to customers, rather than using it to offset the proposed 2017 rate increase, as originally proposed by NSP-Wisconsin. This decision effectively increases NSP-Wisconsin’s requested electric rate increase to $26.9 million, or 3.8 percent.

~~The electric rate request is for the limited purpose~~10.0 percent, an equity ratio of ~~recovering increases in (1) generation~~52.53 percent and ~~transmission fixed charges and fuel and purchased power expenses related to the interchange agreement with NSP-Minnesota, and (2) costs associated with~~a forecasted average net investment rate base of ~~$1.188~~approximately $1.2 billion ~~in 2017.~~

~~The~~for the electric utility and $138.4 million for the natural gas ~~rate request is for the limited purpose of recovering expenses related to the ongoing environmental remediation of a former manufactured gas plant (MGP) site and adjacent area in Ashland, Wis.~~

No changes are being requested to the capital structure or the 10.0 percent ROE authorized by the PSCW in the 2016 rate case. As part of an agreement with stakeholders to limit the size and scope of the case, NSP-Wisconsin also agreed to an earnings cap, solely for 2017, in which 100 percent of the earnings in excess of the authorized ROE would be refunded to customers.utility.

PSCo

Pending and Recently Concluded Regulatory Proceedings — Colorado Public Utilities Commission (CPUC)

Multi-Year Natural Gas Rate Case — In June 2017, PSCo filed a multi-year request with the CPUC seeking to increase retail natural gas rates to recover capital investments and increased operating costs since PSCo’s previous case in 2015. The request, detailed below, is based on forecast test years, a 10.0 percent ROE and an equity ratio of 55.25 percent.

^(a)The roll-in of PSIA rider revenue into base rates will not have an impact on customer bills or total revenue as these costs are already being recovered from customers through the rider. PSCo plans to request new PSIA rates for 2018 in November 2017. The recovery of new, incremental PSIA related investments in 2019 and 2020 are included in the base rate request.

^(b)The additional rate base in 2019 predominantly reflects the roll-in of capital associated with the PSIA rider.

Final rates are expected to be effective in February 2018. In conjunction with the multi-year base rate step increases, PSCo is also proposing a stay-out provision and an earnings test through the end of 2020.

SPS

Pending and Recently Concluded Regulatory Proceedings — Public Utility Commission of Texas (PUCT)

Appeal of the Texas 2015 Electric Rate Case Decision — In 2014, SPS had requested an overall retail electric revenue rate increase of $42.1 million. In 2015, the PUCT approved an overall rate decrease of approximately $4.0 million, net of rate case expenses. In April 2016, SPS filed an appeal, with the Texas State District Court, of the PUCT’s order that had denied SPS’ request for rehearing on certain items in SPS’ Texas 2015 electric rate case related to capital structure, incentive compensation and wholesale load reductions.

~~Table~~ In March 2017, the Travis County District Court denied SPS’ appeal. In April 2017, SPS appealed the District Court’s decision to the Court of ~~Contents~~

In 2014, SPS had requested an overall retail electric revenue rate increase of $64.8 million, which it subsequently revised to $42.1 million. In 2015, the PUCT approved an overall rate decrease of approximately $4.0 million, net of rate case expenses.

~~The hearing in the appeal is scheduled for February 2017.~~

~~Texas 2015 Electric Rate Net Refund Case~~ — Under an agreement in the Texas 2015 electric rate case, the final rates were retroactively applied to June 11, 2015. In June 2016, SPS filed an application to provide a net refund of approximately $1.25 million to reflect the difference in revenue SPS would have received for usage had SPS been charging the final rates approved by the PUCT from June 11, 2015 through Jan. 31, 2016. SPS has proposed to make the net refund over a six-month period beginning October 2016. The application is pending before the PUCT.Appeals.

New Mexico ~~2015~~2016 Electric Rate Case —In ~~October 2015,~~November 2016, SPS filed an electric rate case with the NMPRC seeking an increase in ~~non-fuel~~ base rates of ~~$45.4 million. The proposed~~approximately $41.4 million, representing a total revenue increase ~~would be offset by a decrease in base fuel revenue~~ of approximately ~~$21.1 million.~~10.9 percent. The rate filing is based on a ~~June 30, 2015 HTY adjusted for known and measurable changes, a~~ requested ROE of ~~10.25~~10.1 percent, an equity ratio of 53.97 percent, an electric rate base of approximately ~~$734~~$832 million and ~~an equity ratio of 53.97 percent.~~a future test year ending June 30, 2018.

In May 2016, SPS, the NMPRC Staff and all other parties filed a unanimous black-box stipulation that resolves all issues in the case. Under the stipulation, SPS will implement a non-fuel base rate increase of $23.5 million and a decrease in base fuel revenue of approximately $21.1 million. The decrease in base fuel revenue will be reflected in adjustments collected through the fuel and purchased power cost adjustment clause. The stipulation places no restriction on when SPS may file its next base rate case.

~~In July 2016,~~On April 10, 2017, the hearing examiner ~~issued a recommendation~~determined that SPS’ rate filing was deficient and recommended the NMPRC extend the procedural schedule by approximately one month and restart the suspension period once it is determined that the ~~NMPRC approve the stipulation.

Pending Regulatory ~~Proceedings~~Proceeding — ~~FERC~~Federal Energy Regulatory Commission (FERC)

Midcontinent Independent System Operator, Inc. (MISO) ROE ~~Complaints/ROE Adder~~Complaints — In November 2013, a group of customers filed a complaint at the FERC against MISO transmission owners (TOs), including NSP-Minnesota and NSP-Wisconsin. The complaint argued for a reduction in the ROE in transmission formula rates in the MISO region from 12.38 percent to 9.15 percent, ~~a prohibition on capital structures in excess of 50 percent equity,~~ and the removal of ROE adders (including those for ~~regional transmission organization~~Regional Transmission Organization (RTO) ~~membership and being an independent transmission company)~~membership), effective Nov. 12, 2013.

In December 2015, an ~~ALJ initial decision~~administrative law judge (ALJ) recommended the FERC approve a base ROE of 10.32 ~~percent. A FERC order is expected~~percent for the MISO TOs. The ALJ found the existing 12.38 percent ROE to be unjust and unreasonable. The recommended 10.32 percent ROE applied a FERC ROE policy adopted in a June 2014 order (Opinion 531). The FERC approved the ALJ recommended 10.32 percent base ROE in an order issued in ~~late~~September 2016. This ROE would be applicable for the 15 month refund period from Nov. 12, 2013 to Feb. 11, 2015, and prospectively from the date of the FERC order. The total prospective ROE would be 10.82 percent, including a 50 basis point adder for RTO membership. Various parties requested rehearing of the September 2016 ~~or in 2017.~~order. The requests are pending FERC action.

In February 2015, a second complaint ~~was filed~~ seeking to reduce the MISO ~~region~~ ROE from 12.38 percent to 8.67 percent prior to any ~~adder. The~~adder was filed with the FERC, ~~set the~~resulting in a second ~~complaint for hearings, and established a~~period of potential refund ~~effective date of~~from Feb. 12, 2015. The MPUC, the North Dakota Public Service Commission (NDPSC), the South Dakota Public Utilities Commission and the DOC joined a joint complainant/intervenor initial brief recommending an ROE of either 8.82 percent or 8.81 percent. FERC staff recommended a ROE of 8.78 percent. The MISO TOs recommended a ROE of 10.92 percent. On2015 to May 11, 2016. In June ~~30,~~ 2016, the ALJ ~~issued an initial decision recommending~~recommended a ROE of 9.7 percent, applying the ~~midpoint~~methodology adopted by the FERC in Opinion 531. A final FERC decision on the second ROE complaint was expected later in 2017, but in April 2017, the United States Court of Appeals for the District of Columbia Circuit (D.C. Circuit) by opinion, vacated and remanded Opinion 531. It is unclear how the D.C.

In April 2016, SPP filed a request with the FERC for a waiver that would allow SPP to recover the charges not billed since 2008. The FERC approved the waiver request in July 2016. SPS is considering whether to seek clarification or rehearing of the FERC order. SPP has indicated it anticipates completing its process and invoicing customers during the fourth quarter of 2016. SPS estimates the charges to be $5 million to $10 million, based on preliminary information. SPS anticipates these costs would be recoverable through regulatory mechanisms.


6.	Commitments and Contingencies

Except to the extent noted below and in Note 5 above, the circumstances set forth in Notes 12, 13 and 14 to the consolidated financial statements included in Xcel Energy Inc.’s Annual Report on Form 10-K for the year ended Dec. 31, ~~2015,~~2016, and in Notes 5 and 6 to the

consolidated financial statements included in Xcel Energy Inc.’s Quarterly Report on Form 10-Q for the quarterly period ended March 31, ~~2016,~~2017 appropriately represent, in all material respects, the current status of commitments and contingent liabilities and are incorporated herein by reference. The following include commitments, contingencies and unresolved contingencies that are material to Xcel Energy’s financial position.

~~Purchased Power Agreements (PPAs)~~PPAs

Under certain PPAs, NSP-Minnesota, PSCo and SPS purchase power from independent power producing entities for which the utility subsidiaries are required to reimburse 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 independent power producing entity.

The Xcel Energy utility subsidiaries had ~~approximately 3,467 MW and 3,698 MW~~approximately 3,537 megawatts (MW) of capacity under long-term PPAs as of June 30, ~~2016~~2017 and Dec. 31, ~~2015,~~2016, with entities that have been determined to be variable interest entities. 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. These agreements have expiration dates through ~~2033.~~2041.

At June 30, ~~2016~~2017 and Dec. 31, ~~2015,~~2016, NSP-Wisconsin had recorded a total liability of ~~$95.0~~$46.8 million and ~~$94.4~~$64.3 million, respectively, for the Site based upon potential remediation and design costs together with estimated outside legal and consultant costs; of which $18.7 million and $17.0 million, respectively, were considered a current liability. NSP-Wisconsin’s potential liability, the actual cost of remediation and the timing of expenditures are subject to change. NSP-Wisconsin also continues to work to identify and access state and federal funds to apply to the remediation cost of the entire site.

The North Dakota Department of Health approved NSP-Minnesota’s proposed cleanup plan in January 2017. The timing and final scope of remediation is dependent on whether reasonable access is provided to NSP-Minnesota to perform and implement the approved cleanup plan. NSP-Minnesota has also initiated insurance recovery litigation in North Dakota. The U.S. District Court for the District of North Dakota agreed to the parties’ request for a stay of the litigation until ~~November 2016 to allow NSP-Minnesota time to further investigate site conditions.~~September 2017.

As of June 30, ~~2016~~2017 and Dec. 31, ~~2015,~~2016, NSP-Minnesota had recorded a liability of ~~$1.6~~$16.4 million and ~~$2.7~~$11.3 million, respectively, for the Fargo MGP Site. The current cost estimate for the remediation of the site is approximately $23.0 million, of which approximately $6.6 million has been spent. In December 2015, the North Dakota Public Service Commission (NDPSC) approved NSP-Minnesota’s request to defer costs associated with the Fargo MGP Site, resulting in deferral of all investigation and response costs with the exception of approximately 12 percent allocable to the Minnesota jurisdiction.

Environmental Requirements

Water and Waste

~~Coal Ash Regulation~~Federal Clean Water Act (CWA) Waters of the United States Rule — ~~Xcel Energy’s operations are subject to federal and state laws that impose requirements for handling, storage, treatment and disposal of solid waste.~~ In ~~April~~ 2015, the EPA and the U.S. Army Corps of Engineers (Corps) published a final rule ~~regulating~~that significantly expands the ~~management~~types of water bodies regulated under the CWA and ~~disposal~~broadens the scope of ~~coal combustion byproducts (coal ash)~~waters subject to federal jurisdiction. The final rule will subject more utility projects to federal CWA jurisdiction, thereby potentially delaying the siting of new generation projects, pipelines, transmission lines and distribution lines, as well as increasing project costs and expanding permitting and reporting requirements. In October 2015, the U.S. Court of Appeals for the Sixth Circuit issued a ~~nonhazardous waste. Under~~nationwide stay of the final rule ~~Xcel Energy’s costs~~and subsequently ruled that it, rather than the federal district courts, had jurisdiction over challenges to ~~manage and dispose~~the rule.

Greenhouse Gas (GHG) Emission Standard for Existing Sources (Clean Power Plan or CPP) — In ~~June~~2015, the EPA issued its final rule for existing power plants. Among other things, the rule requires that state plans include enforceable measures to ensure emissions from existing power plants achieve the EPA’s state-specific interim (2022-2029) and final (2030 and thereafter) emission performance targets.

The CPP was challenged by multiple parties in the D.C. Circuit Court. In February 2016, the ~~D.C Circuit~~U.S. Supreme Court issued an order ~~remanding~~staying the final CPP rule.

In March 2017, President Trump signed an executive order requiring the EPA Administrator to review the CPP rule and if appropriate, publish proposed rules suspending, revising or rescinding it. Accordingly, the EPA has requested that the D.C. Circuit Court hold the litigation in abeyance until the EPA completes its work under the executive order. The D.C. Circuit granted the EPA’s request to hold the litigation in abeyance until June 27, 2017, and is considering briefs by the parties on whether the court should remand the challenges to the EPA rather than holding them in abeyance, to determine whether and how the court continues or ends the stay that currently applies to the CPP. On June 9, 2017, the EPA submitted a proposed rule to the Office of Management and Budget entitled “Review of the rule as a result of partial settlements with these parties. Oral arguments are expected to be heard in the second half of 2016 and a final decision is anticipated in early 2017. Until a final decision is reached in the case, it is uncertain whether the litigation or partial settlements will have any significant impact on results of operations, financial position or cash flows on Xcel Energy.Clean Power Plan.”

~~Air~~

Regional Haze Rules — The regional haze program is designed to address widespread haze that results from emissions from a multitude of sources. ~~In 2005, the EPA amended the best available retrofit technology~~The Best Available Retrofit Technology (BART) requirements of ~~its~~the EPA’s regional haze rules ~~which~~ require the installation and operation of emission controls for industrial facilities emitting air pollutants that reduce visibility in national parks and wilderness areas. Under BART, regional haze plans identify facilities that will have to reduce ~~sulfur dioxide~~Sulfur Dioxide (SO₂₂₎), ~~nitrogen oxide~~Nitrogen Oxide (NOx) and particulate matter ~~(PM)~~ emissions and set emission limits for those facilities. BART requirements can also be met through participation in interstate emission trading programs such as the Clean Air Interstate Rule (CAIR) and its successor, Cross-State Air Pollution Rule (CSAPR). The regional haze plans developed by Minnesota and Colorado have been fully approved and are being implemented in those states. States are required to revise their plans every ten years. The next plans for Minnesota and Colorado will be due in 2021. Texas’ first regional haze plan is still undergoing federal review as described below. President Trump’s Administration has not yet taken any public position regarding its views of the proposed and final regional haze regulations affecting SPS facilities in Texas.

Actions affecting Harrington Units:Texas developed a ~~state implementation plan~~State Implementation Plan (SIP) that finds the CAIR equal to BART for electric generating ~~units (EGUs).~~units. As a result, no additional controls beyond CAIR compliance would be required. In ~~December~~ 2014, the EPA proposed to approve the BART portion of the SIP, with ~~the exception that the EPA would substitute the~~substitution of CSAPR compliance for Texas’ reliance on CAIR. In January 2016, the EPA adopted a final rule that defers its approval of CSAPR compliance as BART until the EPA considers further adjustments to CSAPR emission budgets under the ~~United States Court of Appeals for the District of Columbia Circuit’s (D.C. Circuit)~~D.C. Circuit Court’s remand of the Texas SO₂emission budgets. In March 2016, the EPA requested information under the Clean Air Act (CAA) related to EGUs at SPS’ plants. SPS identified Harrington Units 1 and 2, Jones Units 1 and 2, Nichols Unit 3 and Plant X Unit 4 as BART-eligible units. These units will be evaluated based on their impact on visibility. Additional emission control equipment under the EPA’s BART guidelines for PM, SO₂ and NOx could be required if a unit is determined to “cause or contribute” to visibility impairment. SPS cannot evaluate the impact of additional emission controls until the EPA concludes its evaluation of BART. The EPA is expected to issue a proposed rule in December 2016. In June 2016, the EPA issued a memorandum which allows Texas to voluntarily adopt the CSAPR emission budgets limiting annual SO₂ and NOx emissions and rely on those emission budgets to satisfy Texas’ BART obligations under the regional haze rules. ~~It is not yet known whether the~~The Texas Commission on Environmental Quality ~~(TCEQ) intends~~has not utilized this option. The EPA then published a proposed rule in January 2017 that could have the effect of requiring installation of dry scrubbers to ~~utilize this option.~~reduce SO₂ emissions from Harrington Units 1 and 2. Investment costs associated with dry scrubbers for Harrington Units 1 and 2 could be approximately $400 million. The EPA’s deadline to issue a final rule for Texas is September 2017.

~~In December 2014, the EPA proposed to disapprove the reasonable progress portions of the SIP and instead adopt a federal implementation plan (FIP).~~Actions affecting Tolk units: In January 2016, the EPA adopted a final rule establishing a ~~FIP~~federal implementation plan for the state of ~~Texas.

~~Implementation of~~Revisions to the National Ambient Air Quality Standard (NAAQS) for SOOzone ₂— In 2015, the EPA revised the NAAQS for ozone by lowering the eight-hour standard from 75 parts per billion (ppb) to 70 ppb. In areas where Xcel Energy operates, current monitored air quality concentrations comply with the new standard in the Twin Cities Metropolitan Area in Minnesota and meet the 70 ppb level in the Texas panhandle. In documents issued with the new standard, the EPA projects that both areas will meet the new standard.

In June ~~2016,~~2017, the EPA ~~issued final~~announced that it is delaying designations which found the area near the Tolk plant to be meeting the NAAQS and the areas near the Harrington and Pawnee plants as “unclassifiable.” The area near the Harrington plant is to be monitored for three years and a final designation is expected to be made by December 2020. It is anticipated that the area near the Pawnee plant will be able to show compliance with the NAAQS through air dispersion modeling performed by the Colorado Department of Public Health and Environment.

~~If an area is designated nonattainment in 2020, the respective states will need to evaluate all SO~~₂ ~~sources in the area. The state would then submit an implementation plan, which would be due by 2022, designed to achieve the NAAQS by 2025. The TCEQ could require additional SO~~₂ controls at Harrington as part of such a plan. The areas near the remaining Xcel Energy power plants will be evaluated in the next designation phase, ending December 2017. The remaining plants, PSCo’s Comanche and Hayden plants along with NSP-Minnesota’s King and Sherco plants, utilize scrubbers to control SO₂ ~~emissions. Xcel Energy cannot evaluate the impacts until the designation~~ of nonattainment areas ~~is made and any required state plans are developed.

Legal Contingencies

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 the loss or a range of loss is estimable, often involves a series of complex judgments about future events. Management maintains accruals for such losses that are 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. 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, arising from such current proceedings would have a material effect on Xcel Energy’s financial statements. Unless otherwise required by GAAP, legal fees are expensed as incurred.

Employment, Tort and Commercial Litigation

~~Pacific Northwest FERC Refund Proceeding —~~ A complaint with the FERC posed that sales made in the Pacific Northwest in 2000 and 2001 through bilateral contracts were unjust and unreasonable under the Federal Power Act. The City of Seattle (the City) alleges between ~~$34 million~~ to $50 million in sales with PSCo is subject to refund. In 2003, the FERC terminated the proceeding, although it was later remanded back to the FERC in 2007 by the U.S. Court of Appeals for the Ninth Circuit (Ninth Circuit).

In May 2015, in the remand proceeding, the FERC issued an order rejecting the City’s claim that any of the sales made resulted in an excessive burden and concluded that the City failed to establish a causal link between any contracts and any claimed unlawful market activity. In February 2016, the City appealed this decision to the Ninth Circuit. This appeal is pending review by the Ninth Circuit.

Also in December 2015, the Ninth Circuit issued an order and held that the standard of review applied by the FERC to the contracts which the City was challenging is appropriate. The Ninth Circuit dismissed questions concerning whether the FERC properly established the scope of the hearing, and determined that the challenged orders are preliminary and that the Ninth Circuit lacks jurisdiction to review evidentiary decisions until after the FERC’s proceedings are final. The City joined the State of California in its request seeking rehearing of this order, which the Ninth Circuit denied.

Preliminary calculations of the City’s claim for refunds from PSCo are approximately $28 million, excluding interest, or approximately $60 million, including interest. PSCo has concluded that a loss is reasonably possible; however, given the surrounding uncertainties, PSCo is currently unable to estimate the amount or range of reasonably possible loss in the event of an adverse outcome of this matter. If a loss were sustained, PSCo would attempt to recover those losses from other PRPs. No accrual has been recorded for this matter.

Gas Trading Litigation — e prime, inc. (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. Thirteen lawsuits were commenced against e prime and Xcel Energy (and NSP-Wisconsin, in two instances) between 2003 and 2009 alleging fraud and anticompetitive activities in conspiring to restrain the trade of natural gas and manipulate natural gas prices.

The cases were consolidated in U.S. District Court in Nevada. Five of the cases have since been settled and seven ~~have been dismissed.

Line Extension Disputes — In December 2015, Development Recovery Company (DRC) filed a lawsuit in Denver State 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 entered into by PSCo and various developers. The dispute involves ~~assigned interests in those~~ claims by over fifty developers. In May 2016, the district court granted PSCo’s motion to dismiss the lawsuit, concluding that jurisdiction over this dispute resides with the CPUC. In June 2016, DRC appealed the district court’s dismissal of the lawsuit, and the Colorado Court of Appeals affirmed the lower court decision in favor of PSCo. In July 2017, DRC filed a ~~notice of appeal.~~petition to appeal the decision with the Colorado Supreme Court. It is uncertain whether the Colorado Supreme Court will grant the petition. DRC also brought a proceeding before the CPUC as assignee on behalf of two developers, Ryland Homes and Richmond Homes of Colorado. In March 2016, the ALJ issued an order rejecting DRC’s claims for additional allowances and refunds. In June 2016, the ALJ’s determination was approved by the CPUC. DRC did not file a request for reconsideration before the CPUC contesting the decision, but filed an appeal in Denver District Court in August 2016. DRC has requested a hearing for oral arguments, which has yet to be granted or set by the Denver District Court.

PSCo has concluded that a loss is remote with respect to this matter as the service agreements were developed to implement CPUC approved tariffs and PSCo has complied with the tariff provisions. Also, if a loss were sustained, PSCo believes it would be allowed to recover these costs through traditional regulatory mechanisms. The amount or range in dispute is presently unknown and no accrual has been recorded for this matter.

7.	Borrowings and Other Financing Instruments

Short-Term Borrowings

Money Pool — Xcel Energy Inc. and its utility subsidiaries have established a money pool arrangement that allows for short-term investments in and borrowings between the utility subsidiaries. NSP-Wisconsin does not participate in the money pool. Xcel Energy Inc. may make investments in the utility subsidiaries at market-based interest rates; however, the money pool arrangement does not allow the utility subsidiaries to make investments in Xcel Energy Inc. The money pool balances are eliminated in consolidation.

8.	Fair Value of Financial Assets and Liabilities

Fair Value Measurements

The accounting guidance for fair value measurements and disclosures provides a single definition of fair value and requires certain disclosures about assets and liabilities measured at fair value. A hierarchical framework for disclosing the observability of the inputs utilized in measuring assets and liabilities at fair value is established by this guidance. The three levels in the hierarchy are as follows:

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.

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:

Cash equivalents — The fair values of cash equivalents are generally based on cost plus accrued interest; money market funds are measured using quoted ~~prices.~~net asset value (NAV).

Investments in equity securities and other funds — Equity securities are valued using quoted prices in active markets. The fair values for commingled funds ~~international equity funds, private equity investments and real estate investments~~ are measured using ~~a net asset value (NAV) methodology,~~NAVs, which ~~takes~~take into consideration the value of underlying fund investments, as well as the other accrued assets and liabilities of a fund, in order to determine a per-share market value. The investments in commingled ~~funds and international equity~~ funds may be redeemed for NAV with proper notice. Proper notice varies by fund and can range from daily with one or two days notice to annually with 90 days notice. Private equity 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 investments may be redeemed with proper notice, which is typically quarterly with 45-90 days notice; however, withdrawals from real estate investments 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 — The fair values of interest rate derivatives are based on broker quotes that utilize current market interest rate forecasts.

~~Table of Contents~~

Commodity derivatives — The methods used to measure the fair value of commodity derivative forwards and options utilize forward prices and volatilities, as well as pricing adjustments for specific delivery locations, and are generally assigned a Level 2.2 classification. When contractual settlements extend to periods beyond those readily observable on active exchanges or quoted by brokers, the significance of the use of less observable forecasts of long-term 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 financial transmission rights (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 ~~energy congestion, which is caused by~~transmission congestion. In addition to overall transmission load, ~~and transmission constraints. Congestion~~congestion is also influenced by the operating schedules of power plants and the consumption of ~~electricity.~~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. The valuation process for FTRs utilizes complex iterative modeling to predict the impacts of forecasted changes in these drivers of transmission system congestion on the historical pricing of FTR purchases.

Table of Contents

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~~Fair value measurements for FTRs have been assigned a Level 3 given the limited observability of management’s forecasts for several of the inputs to this complex valuation ~~model fair value measurements for FTRs have been assigned a Level 3. Monthly~~model. Non-trading monthly FTR settlements ~~for non-trading FTRs~~ 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 to the complex model used for valuation of FTRs are insignificant to the consolidated financial statements of Xcel Energy.

Non-Derivative Instruments Fair Value Measurements

Nuclear Decommissioning Fund

The ~~NRC~~Nuclear Regulatory Commission (NRC) requires NSP-Minnesota to maintain a portfolio of investments to fund the costs of decommissioning its nuclear generating plants. Together with all accumulated earnings or losses, the assets of the nuclear decommissioning fund are legally restricted for the ~~purpose of~~ decommissioning the Monticello and PI nuclear generating plants. The fund contains cash equivalents, debt securities, equity securities and other investments – all classified as available-for-sale. NSP-Minnesota plans to reinvest matured securities until decommissioning begins. 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 of its nuclear generating plants over the lives of the plants, assuming rate recovery of all costs. ~~Realized~~Given the purpose and legal restrictions on the use of nuclear decommissioning fund assets, 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, given the purpose and legal restrictions on the use of nuclear decommissioning fund assets.~~costs. Consequently, any realized and unrealized gains and losses on securities in the nuclear decommissioning fund, including any other-than-temporary impairments, are deferred as a component of the regulatory asset for nuclear decommissioning.

Unrealized gains for the nuclear decommissioning fund were ~~$336.5~~$462.3 million and ~~$328.8~~$378.6 million at June 30, ~~2016~~2017 and Dec. 31, ~~2015,~~2016, respectively, and unrealized losses and amounts recorded as other-than-temporary impairments were ~~$95.2~~$34.2 million and ~~$100.2~~$46.9 million at June 30, ~~2016~~2017 and Dec. 31, ~~2015,~~2016, 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.

At June 30, ~~2016,~~2017, accumulated other comprehensive losses related to interest rate derivatives included ~~$3.4~~$3.0 million of net losses expected to be reclassified into earnings during the next 12 months as the related hedged interest rate transactions impact earnings, including forecasted amounts for unsettled hedges, as applicable.

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 ~~energy-related instruments.~~natural gas-related instruments, including derivatives. Xcel Energy’s risk management policy allows management to conduct these activities within guidelines and limitations as approved by its risk management ~~committee.~~committee, which is made up of management personnel not directly involved in the 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.

~~Table of Contents~~

At June 30, ~~2016,~~2017, Xcel Energy had various vehicle fuel contracts designated as cash flow hedges extending through December ~~2016.~~2018. Xcel Energy ~~also~~ enters into derivative instruments that mitigate commodity price risk on behalf of electric and natural gas customers, but ~~are~~may not be designated as qualifying hedging transactions. Changes in the fair value of non-trading commodity derivative instruments are recorded in 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. Xcel Energy recorded immaterial amounts to income related to the ineffectiveness of cash flow hedges for the three and six months ended June 30, ~~2016~~2017 and ~~2015.~~2016.

At June 30, ~~2016,~~2017, net ~~losses~~gains related to commodity derivative cash flow hedges recorded as a component of accumulated other comprehensive losses included ~~$0.1 million of net losses~~immaterial amounts expected to be reclassified into earnings during the next 12 months as the hedged transactions occur.

Additionally, Xcel Energy 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.

Xcel Energy had no derivative instruments designated as fair value hedges during the three and six months ended June 30, ~~2016~~2017 and ~~2015.~~2016. Therefore, no gains or losses from fair value hedges or related hedged transactions were recognized for these periods.

Consideration of Credit Risk and Concentrations — Xcel Energy continuously monitors the creditworthiness of the counterparties to its interest rate derivatives and commodity derivative contracts prior to settlement, and assesses each counterparty’s ability to perform on the ~~transactions.~~transactions set forth in the contracts. Given this assessment, as well as an assessment of the impact of Xcel Energy’s own credit risk when determining the fair value of derivative liabilities, the impact of ~~considering~~ credit risk was immaterial to the fair value of unsettled commodity derivatives presented in the consolidated balance sheets.

Xcel Energy Inc. and its subsidiaries employ additional credit risk control mechanisms when appropriate, such as letters of credit, parental guarantees, standardized master netting agreements and termination provisions that allow for offsetting of positive and negative exposures. Credit exposure is monitored and, when necessary, the activity with a specific counterparty is limited until credit enhancement is provided.

Table of Contents

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. At June 30, ~~2016, one~~2017, two of Xcel Energy’s 10 most significant counterparties for these activities, comprising ~~$13.5~~$28.1 million or 612 percent of this credit exposure, had investment grade credit ratings from Standard & Poor’s, ~~Ratings Services,~~ Moody’s ~~Investor Services~~ or Fitch Ratings. ~~Seven~~Eight of the 10 most significant counterparties, comprising ~~$55.6~~$75.7 million or 2532 percent 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. The remaining two most significant counterparties, comprising $12.2 million or 6 percent of this credit exposure, had credit quality less than investment grade, based on ratings from external and internal analysis. NineAll ten of these significant counterparties are ~~RTOs,~~ municipal or cooperative electric entities or other utilities.

Credit Related Contingent Features — Contract provisions for derivative instruments that the utility subsidiaries enter, including ~~those recorded to the consolidated balance sheet at fair value, as well as~~ those accounted for as normal purchase-normal sale contracts and therefore not reflected on the balance sheet, may require the posting of collateral or settlement of the contracts for various reasons, including if the applicable utility subsidiary is unable to maintain its credit ratings. At June 30, ~~2016~~2017 and Dec. 31, ~~2015,~~2016, there were no derivative instruments in a liability position with underlying contract provisions that ~~would have~~ required the posting of collateral or settlement of applicable outstanding contracts if the credit ratings of Xcel Energy Inc.’s utility subsidiaries were downgraded below investment grade.

Certain derivative instruments are also subject to contract provisions that contain adequate assurance clauses. These 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 no collateral posted related to adequate assurance clauses in derivative contracts as of June 30, ~~2016~~2017 and Dec. 31, ~~2015.~~2016.

In 2003, as a result of implementing new guidance on the normal purchase exception for derivative accounting, Xcel Energy began recording several long-term PPAs at fair value due to accounting requirements related to underlying price adjustments. As these purchases are recovered through normal regulatory recovery mechanisms in the respective jurisdictions, the changes in fair value for these contracts were offset by regulatory assets and liabilities. During 2006, Xcel Energy qualified these contracts under the normal purchase exception. Based on this qualification, the contracts are no longer adjusted to fair value and the previous carrying value of these contracts will be amortized over the remaining contract lives along with the offsetting regulatory assets and liabilities.

Xcel Energy nets derivative instruments and related collateral in its consolidated balance sheet when supported by a legally enforceable master netting agreement, and all derivative instruments and related collateral amounts were subject to master netting agreements at June 30, ~~2016.~~2017. At June 30, ~~2016,~~2017, derivative assets and liabilities include no obligations to return cash collateral and the rights to reclaim cash collateral of ~~$4.7~~$3.5 million. The counterparty netting amounts presented exclude settlement receivables and payables and non-derivative amounts that may be subject to the same master netting agreements.

10.	Segment Information

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 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. 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 utility, regulated natural gas utility and all other.

Xcel Energy’s regulated electric utility segment generates, transmits and distributes electricity primarily in portions of 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. Regulated electric utility also includes commodity trading operations.

Xcel Energy’s regulated natural gas utility segment transports, stores and distributes natural gas primarily in portions of Minnesota, Wisconsin, North Dakota, Michigan and Colorado.

Revenues from operating segments not included above are below the necessary quantitative thresholds and are therefore included in the all other category. Those primarily include steam revenue, appliance repair services, nonutility 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 ~~$133.7~~$133.2 million and ~~$130.0~~$132.8 million as of June 30, ~~2016~~2017 and Dec. 31, ~~2015,~~2016, respectively, included in the regulated natural gas utility segment.

Asset and capital expenditure information is not provided for Xcel Energy’s reportable segments because as an integrated electric and natural gas utility, Xcel Energy operates significant assets that are not dedicated to a specific business segment, and 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.

~~Table of Contents~~

To report income from operations for regulated electric and regulated natural gas utility segments, the majority of costs are directly assigned to each segment. However, some costs, such as common depreciation, common O&M expenses and interest expense are allocated based on cost causation allocators. A general allocator is used for certain general and administrative expenses, including office supplies, rent, property insurance and general advertising.

11.	Earnings Per Share

Basic earnings per share (EPS) was computed by dividing the earnings available to Xcel Energy Inc.’s common shareholders by the weighted average number of common shares outstanding during the period. Diluted EPS was computed by dividing the earnings available to Xcel Energy Inc.’s common shareholders by the diluted weighted average number of common shares outstanding during the period. 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.

Common Stock Equivalents — Xcel Energy Inc. currently has common stock equivalents related to certain equity awards in share-based compensation arrangements.

Common stock equivalents causing dilutive impact to EPS include commitments to issue common stock related to time based equity compensation ~~awards and time based employer matching contributions to certain 401(k) plan participants.~~

~~Table of Contents~~

awards.

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, granted to settle amounts due to certain employees under the Xcel Energy Inc. Executive Annual Incentive Award Plan, is included in common shares outstanding when granted.

Table of Contents

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.

Liability awards subject to a performance condition; any portions settled in shares are included in common shares outstanding upon settlement.

The dilutive impact of common stock equivalents affecting EPS was as follows:

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.

Forward-Looking Statements

Except for the historical statements contained in this report, the matters discussed herein, are forward-looking statements that are subject to certain risks, uncertainties and assumptions. Such forward-looking statements, including our ~~2016~~2017 earnings per share guidance and assumptions, are intended to be identified in this document by the words “anticipate,” “believe,” “estimate,” “expect,” “intend,” “may,” “objective,” “outlook,” “plan,” “project,” “possible,” “potential,” “should” and similar expressions. Actual results may vary materially. Forward-looking statements speak only as of the date they are made, and we expressly disclaim any obligation to update any forward-looking information. The following factors, in addition to those discussed elsewhere in this Quarterly Report on Form 10-Q and in other securities filings (including Xcel Energy’s Annual Report on Form 10-K for the fiscal year ended Dec. 31, ~~2015~~2016, and ~~Quarterly Report on Form 10-Q for the quarter ended March 31, 2016),~~subsequent securities filings, could cause actual results to differ materially from management expectations as suggested by such forward-looking information: general economic conditions, including inflation rates, monetary fluctuations and their impact on capital expenditures and the ability of Xcel Energy Inc. and its subsidiaries (collectively, Xcel Energy) to obtain financing on favorable terms; business conditions in the energy industry; including the risk of a slow down in the U.S. economy or delay in growth, recovery, trade, fiscal, taxation and environmental policies in areas where Xcel Energy has a financial interest; customer business conditions; actions of credit rating agencies; competitive factors including the extent and timing of the entry of additional competition in the markets served by Xcel Energy and its subsidiaries; unusual weather; effects of geopolitical events, including war and acts of terrorism; cyber security threats and data security breaches; state, federal and foreign legislative and regulatory initiatives that affect cost and investment recovery, have an impact on rates or have an impact on asset operation or ownership or impose environmental compliance conditions; structures that affect the speed and degree to which competition enters the electric and natural gas markets; costs and other effects of legal and administrative proceedings, settlements, investigations and claims; financial or regulatory accounting policies imposed by regulatory bodies; outcomes of regulatory proceedings; availability ofor cost of capital; and employee work force factors.

Financial Review

The only common equity securities that are publicly traded are common shares of Xcel Energy Inc. The 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. Ongoing diluted EPS for Xcel Energy and by subsidiary is a financial measure not recognized under GAAP. Ongoing diluted EPS is calculated by dividing the net income or loss attributable to the controlling interest of each subsidiary, adjusted for certain items, by the weighted average fully diluted Xcel Energy Inc. common shares outstanding for the period. We use this non-GAAP financial measure to evaluate and provide details of Xcel Energy’s core earnings and underlying performance. We believe this measurement is useful to investors in facilitating period over period comparisons and evaluating or projecting financial results. This non-GAAP financial measure should not be considered as an alternative to measures calculated and reported in accordance with GAAP.

Earnings Adjusted for Certain Items (Ongoing Earnings)

Ongoing earnings reflect adjustments to GAAP earnings for certain items. Xcel Energy’s management believes that ongoing earnings provide a meaningful comparison of earnings results and is representative of Xcel Energy’s fundamental core earnings power. Xcel Energy’s management uses ongoing earnings internally for financial planning and analysis, for reporting of results to the Board of Directors, in determining whether performance targets are met for performance-based compensation, and when communicating its earnings outlook to analysts and investors.

For the six months ended June 30, 2015, GAAP earnings included a $0.16 per share charge related to the Monticello nuclear facility LCM/EPU project, which in total cost $748 million. In March 2015, the MPUC approved full recovery, including a return, on $415 million of the project costs, inclusive of AFUDC, but only allowed recovery of the remaining $333 million of costs with no return on this portion of the investment for years 2015 and beyond. As a result of this decision, Xcel Energy recorded a pre-tax charge of approximately $129 million in the first quarter of 2015. See Note 5 to the consolidated financial statements for further discussion.

NSP-Minnesota — Earnings increased $0.02 per share for the second quarter of ~~2016~~2017 and year-to-date. The year-to-date increase in earnings was due to higher electric margins driven by the rate case in Minnesota, as well as increased natural gas margins, non-fuel riders and lower O&M expenses, partially offset by increased depreciation.

SPS — Earnings increased $0.01 per share year-to-date. Year-to-date, the positive impact of higher natural gas revenues due to rate increases was more than offset by higher depreciation, O&M expenses, interest charges and the favorable impact of an adjustment to the estimated electric earnings test refund obligation recognized in 2015.

Statement of Income Analysis

The following discussion 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 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 the average customer historically uses per degree of temperature. Accordingly, deviations in weather from normal levels can affect Xcel Energy’s financial performance.

Degree-day or Temperature-Humidity Index (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) 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) 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-year 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 as defined above to derive the amount of demand associated with the weather impact.

The percentage increase (decrease) in normal and actual HDD, CDD and THI is provided in the following table:

Electric revenues and fuel and purchased power expenses are largely impacted by the fluctuation in the price of natural gas, coal and uranium used in the generation of electricity, but as a result of the design of fuel recovery mechanisms to recover current expenses, these price fluctuations have minimal impact on electric margin. The following table details the electric revenues and margin:

~~NSP-Minnesota~~Xcel Energy Inc.

~~NSP System Resource Plans~~Wind Development — ~~In January 2015,~~During the first quarter of 2017, Xcel Energy announced plans to significantly expand its wind capacity by adding 1,550 MW of new wind generation at NSP-Minnesota ~~filed its 2016-2030 Integrated Resource Plan (the Plan) with the MPUC.~~and 1,230 MW at SPS. Previously, Xcel Energy received regulatory approval to build a 600 MW wind farm at PSCo.

~~Subsequently, NSP-Minnesota proposed revisions~~In July 2017, the MPUC approved NSP-Minnesota’s proposal to ~~the Plan, which addressed stakeholder recommendations as well as the Clean Power Plan (CPP) issued~~add 1,550 MW of new wind generation, including ownership of 1,150 MW of wind generation by ~~the EPA.~~NSP-Minnesota. The revised Plan is based on four primary elements: (1) accelerate the transition from coal energy to renewables, (2) preserve regional system reliability, (3) pursue energy efficiency gains and grid modernization, and (4) ensure customer benefits. The provisions included in the Plan would allow for a 60 percent reduction in carbon emissions from 2005 levels by 2030 and is expected to result in 63 percent of NSP System energy being carbon-free by 2030.

In January 2016, NSP-Minnesota filed supplemental economic and technical information in support of its revised Plan. Additionally, NSP-Minnesota addressed forecasted cost increases at PI (through end of licensed life) and committed to provide additional information if the MPUC wishes to further explore alternatives to operating PI through its current license periods. In July 2016, the DOC submitted its comments, which:

~~Concluded NSP-Minnesota’s revised Plan is the most cost-effective after analyzing alternative retirement scenarios for Sherco Units 1 and 2 and a possible retirement of the King plant;~~

~~Recommended a separate detailed analysis of early PI retirement;~~

~~Recommended no additional solar beyond the community solar gardens program for the first five years; and~~

~~Recommended~~total, Xcel Energy has proposed adding ~~up to 1,000~~3,380 MW of wind capacity by ~~2019.~~the end of 2020. Xcel Energy has filed to own and place in rate base 2,750 MW of these wind projects, while 630 MW would be through PPAs. These wind projects would qualify for 100 percent of the production tax credit and are intended to provide billions of dollars of savings to our customers and substantial environmental benefits. Projected savings/benefits assume fuel costs and generation mix consistent with those included in various commission approved resource plans and generation need filings.

NSP-Minnesota

PPA Terminations and Amendments — In June and July 2017, NSP-Minnesota filed requests with the MPUC and/or the NDPSC for several initiatives including changes to four PPAs to reduce future costs for customers. These actions include the following:

The ~~MPUC is expected~~termination of a PPA with Benson Power LLC (Benson) for its 55 MW biomass facility in Benson, Minn. The termination of the Benson PPA requires FERC approval and would result in payments of $95 million to ~~make~~terminate the PPA and acquire the facility, as well as additional expenditures of approximately $26 million to temporarily operate then close the facility.

The termination of a ~~decision~~PPA with Laurentian Energy Authority I, LLC (Laurentian) for its 35 MW of biomass facilities in Hibbing and Virginia, Minn. The termination of the Laurentian PPA would result in $108.5 million of contract cancellation payments over six years.

The remaining two requested PPA changes involve a PPA extension for a 34 MW waste-to-energy facility at a price reflective of current market conditions and termination of another 12 MW waste-to-energy PPA.

NSP-Minnesota has requested recovery of all costs associated with these changes through the Fuel Clause Adjustment, including a return on NSP-Minnesota’s total investment in the ~~Plan~~Benson transaction over the remaining life of the current PPA through 2028. If approved, these actions together are intended to provide approximately $653 million in ~~late 2016.~~net cost savings to customers over the next 10 years.

NSP-Wisconsin

NSP-Wisconsin / American Transmission Company, LLC (ATC) - La Crosse to Madison, Wis. Transmission Line — In 2013, NSP-Wisconsin and ATC jointly filed an application with the PSCW for a certificate of public convenience and necessity (CPCN) for a new 345 kilovolt transmission line that would extend from La Crosse, Wis. to Madison, Wis. NSP-Wisconsin’s half of the line will be shared with three co-owners, Dairyland Power Cooperative, WPPI Energy and Southern Minnesota Municipal Power Agency-Wisconsin.

In 2015, ~~Electric Fuel Cost Recovery~~ ~~— NSP-Wisconsin’s electric fuel costs~~the PSCW issued its order approving a CPCN and route for the ~~year ended Dec. 31, 2015 were lower than authorized in rates and outside~~project. Two groups have appealed the ~~two percent annual tolerance band established in~~CPCN order to the La Crosse County Circuit Court (Circuit Court). In May 2017, the Circuit Court determined that the project was necessary, allowing construction to continue on a seven mile segment near La Crosse, Wis. The parties have appealed various aspects of the case to the Wisconsin ~~fuel cost recovery rules, primarily~~Court of Appeals, which is currently pending. The CPCN remains in full effect unless one of the parties seeks and receives a stay from the court and posts a bond to cover damages the utilities may incur due to ~~lower load as a result~~delay. The 180-mile project is expected to cost approximately $541 million. NSP-Wisconsin’s portion of ~~mild weather, lower natural gas prices and lower purchased power prices~~the investment, which includes AFUDC, is estimated to be approximately $200 million. Construction on the line began in ~~the MISO market. NSP-Wisconsin recorded a deferral of approximately $9.2 million through Dec. 31, 2015. In July~~January 2016, ~~the PSCW required NSP-Wisconsin to provide a direct refund of $9.5 million to customers. Accordingly, NSP-Wisconsin plans to apply the refund to customer bills based on usage in September 2016.~~with completion anticipated by late 2018.

2016 Electric Fuel Cost Recovery — NSP-Wisconsin’s electric fuel costs for the ~~six months~~year ended ~~June 30,~~Dec. 31, 2016 were lower than authorized in rates and outside the two percent annual tolerance band established in the Wisconsin fuel cost recovery rules, primarily due to lower sales volume and lower purchased power costs coupled with moderate weather. Under the fuel cost recovery rules, NSP-Wisconsin may retain the amount of over-recovery up to two percent of authorized annual fuel costs, or approximately ~~$3.5~~$3.4 million. However, NSP-Wisconsin must defer the amount of over-recovery in excess of the two percent annual tolerance band for future refund to customers. In July 2017, the PSCW required NSP-Wisconsin to provide a refund of $9.5 million to customers, which is expected to start in September 2017.

2017 Electric Fuel Cost Recovery — NSP-Wisconsin’s electric fuel costs for the six months ended June 30, 2017 were lower than authorized in rates and outside the two percent annual tolerance band established in the Wisconsin fuel cost recovery rules, primarily due to lower sales volume and lower purchased power costs coupled with moderate weather and generation sales into the MISO market. Under the fuel cost recovery rules, NSP-Wisconsin may retain the amount of over-recovery up to two percent of authorized annual fuel costs, or approximately $3.7 million. However, NSP-Wisconsin must defer the amount of over-recovery in excess of the two percent annual tolerance band for future refund to customers. Accordingly, NSP-Wisconsin recorded a deferral of approximately ~~$3.3~~$3.0 million through June 30, ~~2016.~~2017. The amount of the deferral could increase or decrease based on actual fuel costs incurred for the remainder of the year. In the first quarter of ~~2017,~~2018, NSP-Wisconsin will file a reconciliation of ~~2016~~2017 fuel costs with the PSCW. The amount of any potential refund is subject to review and approval by the PSCW, which is not expected until ~~mid-2017.~~mid-2018.

PSCo

~~Colorado 2017 Electric Resource Plan~~ — In May 2016, PSCo filed its 2017 Electric Resource Plan which identified approximately 600 MW of additional resources need by the summer of 2023. The CPUC is expected to consider the resource plan in two phases. In the first phase, the CPUC will examine the resource need to address peak demand periods, establish the resource acquisition period and determine modeling parameters used in resource selection for the second phase. The second phase would include solicitation of new resources. PSCo’s base plan, filed in Phase I, addressed various resources including 410 MW of combined cycle generation, 700 MW of combustion turbine generation and approximately 600 MW of customer sited solar generation. Additional scenarios to the plan include adding 600 MW of the Rush Creek Wind Project or 400 MW of wind or utility solar generation. The first phase of the Electric Resource Plan is anticipated to conclude in the second quarter of 2017 with the second phase to begin shortly after.

~~Brush to Castle Pines 345 Kilovolt (KV) Transmission Line~~ — In April 2015, the CPUC granted a certificate of public convenience and necessity (CPCN) to construct a new 345 KV transmission line originating from Pawnee generating station, near Brush, CO to the Daniels Park substation, near Castle Pines, CO to be placed in service by May 2022. The estimated project cost is $178.3 million. The CPUC’s decision requires that project construction begin no earlier than May 2020 to meet resource needs by 2023.

In April 2016, PSCo filed a petition with the CPUC to request that construction begin as early as February 2017 for the project to be placed in service by October 2019. This project was proposed to support the interconnection of new generation at PSCo’s Pawnee or Missile Site substations. As the Rush Creek Wind Project interconnects at the Missile Site substation, parties have requested that PSCo’s petition to start construction in 2017 be consolidated with the Rush Creek Wind Project. The CPUC granted the request for consolidation and a decision on the petition is expected by November 2016.

Rush Creek Wind Ownership Proposal — In ~~May~~ 2016, the CPUC granted PSCo ~~filed an application~~a CPCN to build, own and operate a 600 MW wind generation facility in Colorado at Rush Creek. The CPCN includes a hard cost-cap of $1.096 billion (including transmission costs) and a capital cost sharing mechanism between customers and PSCo of ~~approximately $1 billion, including transmission investment.~~82.5 percent to customers and 17.5 percent to PSCo ~~requested approval of the proposal by November 2016, in order to commence~~for every $10 million the project ~~timely and capture~~comes in below the ~~full production tax credit benefit for customers.~~cost-cap.

~~Colorado legislation allows~~All major contracts required to complete the project have been executed including the Vestas turbine supply and balance of plant agreements. Vestas PTC components for ~~utilities to own up to 50 percent~~safe harboring the facility have been fabricated and are currently being stored at Vestas facilities in Colorado. Construction of ~~new renewable resources without a competitive bidding process if projects can be developed at a reasonable price~~roads, collection systems, and ~~demonstrate economic benefit.~~ foundations began in April 2017.

In June 2017, PSCo ~~believes~~filed its ~~proposed facility can~~report required under Colorado rules that require PSCo to consider Best Value Employment Metrics (BVEM) as a factor in selecting contractors for generation projects. On July 5, 2017, several building trades filed comments arguing that PSCo’s Balance of Plant Contractor selection was inappropriate as it did not follow a more detailed and quantitative analysis. The trade unions argued that the BVEM deficiencies could be ~~constructed at~~remedied through execution of a ~~reasonable cost compared to the cost of similar renewable resources available~~Project Labor Agreement on the ~~market, and~~project. PSCo filed its reply indicating that it ~~will be able to demonstrate to~~satisfied the ~~CPUC and the independent evaluator that the proposed wind project meets the reasonable price and economic benefit standards.

~~Intervenors responded to PSCo’s application and answer testimony was filed in July 2016. The next steps in the procedural schedule are as follows:~~

~~PSCo’s rebuttal testimony — Aug. 22, 2016; and~~

~~Hearings — Sept. 7-9, 2016.~~

~~Natural Gas Reserves Investments~~2016 Electric Resource Plan (ERP) — In ~~January~~May 2016, PSCo filed ~~a request with the CPUC~~its 2016 ERP which included its estimated need for approval of a long-term natural gas procurement and price hedging framework. In June 2016, PSCo withdrew its application as it concluded that the litigation of the application would be contentious and, as structured, the framework would not address many of the concerns raised about the program by various intervenors. PSCo will continue to examine opportunities to mitigate price volatility for its customers.

~~Joint Dispatch Agreement (JDA)~~ — In February 2016, the FERC approved a JDA between PSCo, Black Hills Colorado Electric Utility Company, LP and Platte River Power Authority. Through the JDA, energy is dispatched to economically serve the combined electric customer loads of the three systems. In circumstances where PSCo is the lowest cost producer, it will sell its excessadditional generation ~~to other JDA counterparties. Margins on these sales would be shared among PSCo~~resources and its ~~customers,~~proposal to acquire those resources through a competitive Request for Proposal (RFP) process. The CPUC issued its decision on Phase I in late April 2017, approving the Phase I modeling assumptions to be used in Phase II and directed PSCo to file an updated capacity need prior to issuing any RFPs. PSCo plans to update the range of ~~which 10 percent would~~resource need to be ~~retained by PSCo.~~considered within the competitive RFP process and issue the RFP in August 2017. The ~~JDA parties estimate~~CPUC is expected to rule on the ~~combined net benefits of the agreement would be approximately $4.5 million, annually. The agreement~~RFP results in ~~a reduction in total energy costs for~~ the ~~parties,~~second quarter of which approximately $1.4 million would be allocated to PSCo’s customers. As part of the agreement, PSCo will earn a management fee to administer the JDA. Operations under the JDA are expected to begin in August 2016.2018.

Advanced Grid Intelligence and Security —In ~~August 2016, PSCo filed a request with~~July 2017, the CPUC ~~to approve a certificate of public convenience and necessity (CPCN)~~approved PSCo’s CPCN for implementation of its advanced grid initiative. The project incorporates installing advanced meters, implementing ~~a combination of~~ hardware and software applications to allow the distribution system to operate at a lower voltage (integrated volt-var optimization) and installing ~~necessary~~ communications ~~infrastructure to implement this hardware.~~infrastructure. These major projects are expected to improve customer experience, enhance grid reliability and enable the implementation of new and innovative programs and rate structures.

In June 2017, the CPUC approved a settlement, which delayed the advanced meter deployment from 2017-2021 to 2019-2024. The ~~estimated~~total capital ~~investment for~~cost of the project is currently estimated to be approximately ~~$500~~$537 million ~~which is largely included in Xcel Energy’s base~~for 2017-2024. As a result of the settlement, approximately $120 million of capital ~~forecast for 2016-2020. The project would be completed by 2021.~~investment was deferred to 2022-2024.

Decoupling Filing — OnIn July ~~12,~~ 2016, PSCo filed a request with the CPUC to approve a partial decoupling mechanism, ~~for a five year period, effective in 2017. The proposed decoupling adjustment~~which would ~~allow PSCo to~~ adjust annual revenues based on changes in weather normalized average use per customer for the residential and small ~~C&I~~commercial classes.

In July 2017, the CPUC issued a decision which approved the following key decisions regarding decoupling:

Effective Jan. 1, 2018 through December 2023 (subject to establishing new rates in the next electric rate case);

Applicable to the residential class and small commercial class;

Based on total class revenues (subject to establishing the base period in the next electric rate case);

Based on actual sales; and

Subject to a soft cap of 3 percent on any annual adjustment.

PSCo plans to seek reconsideration of the order.

Boulder, Colo. Municipalization — In 2011, Boulder voters passed a ballot measure authorizing the formation of a municipal utility. In 2014, the Boulder City Council passed an ordinance to establish an electric utility. PSCo challenged the formation of this utility as premature because costs and system separation plans were not final. The ~~proposed mechanism is intended to improve~~Boulder District Court dismissed the case for lack of subject matter jurisdiction. PSCo appealed this decision. In September 2016, the Colorado Court of Appeals vacated the District Court’s decision, and ultimately preserved PSCo’s ability to ~~collect base rate revenues~~challenge the utility formation. Boulder subsequently filed a Petition for Writ of Certiorari with the Colorado Supreme Court. The Supreme Court has not yet ruled whether it will exercise its discretion and review the petition.

In January 2015, the Boulder District Court affirmed a prior CPUC decision that Boulder cannot serve customers outside its city limits. The District Court also ruled the CPUC has jurisdiction over the transfer of any facilities to Boulder and how the systems are separated to preserve reliability, safety and effectiveness. In February 2015, the Boulder District Court also dismissed the condemnation action Boulder had filed. The CPUC must approve the separation plan before Boulder files its condemnation proceeding.

In July 2015, Boulder filed an application with the CPUC requesting approval of its proposed separation plan. PSCo filed a motion to dismiss Boulder’s application. The CPUC dismissed a portion of Boulder’s application, but allowed Boulder to supplement its application. Boulder filed its second supplemental application in September 2016. In March 2017, PSCo and other parties filed their testimony outlining their concerns about the Boulder separation plan and raised legal concerns about aspects of the plan. In April 2017, despite extensive negotiations between PSCo and Boulder, the Boulder City Council voted to continue litigation for municipalization. Also, the CPUC ordered Boulder to file a third supplemental separation plan clearly laying out Boulder’s proposal. Boulder proposed a plan that would cost approximately $75 million. Boulder proposed sharing of certain distribution and substation facilities and requested that PSCo be required to construct Boulder’s new facilities and finance the construction. In June 2017, PSCo and other intervenors filed alternatives to Boulder’s separation plan and opposed the sharing; contracting and financing aspects of the plan. Evidentiary hearings began July 26, 2017.

Mountain West Transmission Group (MWTG) — PSCo initiated discussions with six other transmission owners from the Rocky Mountain region to evaluate the merits of creating and operating pursuant to a joint transmission tariff that may increase wholesale market efficiency and improve regional transmission planning. In 2016, the MWTG established a non-binding memorandum of understanding to guide their process and issued a request for information to four established RTOs. In January 2017, the MWTG initiated preliminary discussions with the SPP to begin evaluation of the costs and benefits of MWTG participation in the ~~event that average use per customer declines as a result of DSM, distributed generation~~SPP RTO.

Wholesale Customer Participation in ~~ERCOT~~Electric Reliability Council of Texas (ERCOT) — In March 2016, the PUCT Staff requested comments on Lubbock Power & Light’s (LP&L’s) proposal to transition a portion of its load (approximately 430 MW on a peak basis) to the ERCOT in June 2019. LP&L’s proposal would result in an approximate seven percent reduction of load in SPS, or a loss of approximately $18 million in wholesale transmission ~~revenue based on 2015 revenue requirements.~~revenue. The remaining portion of LP&L’s load (approximately 170 MW) would continue to be served by SPS. Should LP&L join ERCOT, costs to SPS’ remaining customers would increase as SPS’ transmission ~~revenue requirement~~costs would be spread across a smaller base of customers. SPS intends to participate in the PUCT’s proceeding to protect its customers’ interests. LP&L has stated that it intends to file an application with the PUCT for a CCN for approval of the transfer by late 2016.

~~Table of Contents~~

The PUCT has indicated there will be a two-step process regarding LP&L’s possible transfer to ERCOT. The first step will be a proceeding to determine whether the proposed transfer is in the public interest and to consider certain protections for non-LP&L customers who would be affected by LP&L’s transfer. If the PUCT determines the transfer is in the public interest, the second step will be for LP&L to file a CCN application for transmission facilities to connect with ERCOT. The PUCT ~~has stated it~~asked SPP and ERCOT to perform reliability and economic studies to better understand the implications of LP&L’s proposal. SPP and ERCOT filed the studies on June 30, 2017. LP&L is expected to file an application with the PUCT for a public interest determination in August 2017. SPS intends to ~~discuss, and possibly decide, issues regarding procedures, timing, scope of proceedings and types of analyses~~participate in ~~August 2016.~~the PUCT’s processes to protect its customers’ interests.

In May 2016, SPS submitted a filing to the FERC seeking approval to impose an Interconnection Switching Fee (exit fee) associated with LP&L’s proposal. In June 2016, LP&L and Golden Spread Electric Cooperative, Inc. (Golden Spread) protested SPS’ filing. LP&L argued that SPS has no legal authority to impose a charge andNo final decision regarding LP&L’s departure ~~would reduce certain costs to SPS and asked the FERC to reject the filing. Golden Spread asked FERC to clarify that if the exit fee~~or its potential timing is ~~not approved, remaining wholesale transmission customers could challenge future recovery of SPS’ costs.

Summary of Recent Federal Regulatory Developments

~~The Pipeline and Hazardous Materials Safety Administration~~

~~Pipeline Safety Act~~ — The Pipeline Safety, Regulatory Certainty, and Job Creation Act (Pipeline Safety Act) requires additional verification of pipeline infrastructure records by pipeline owners and operators to confirm the maximum allowable operating pressure of lines located in high consequence areas or more-densely populated areas. The DOT Pipeline and Hazardous Materials Safety Administration (PHMSA) recently released proposed rules that address this verification requirement along with a number of other significant changes to gas transmission regulations. These changes include requirements around use of automatic or remote-controlled shut-off valves; testing of certain previously untested transmission lines; and expanding integrity management requirements. The Pipeline Safety Act also includes a maximum penalty for violating pipeline safety rules of $2 million per day for related violations.

Xcel Energy recently commented on the proposed rules and continues to analyze the proposed rule changes as they relate to costs, current operations and financial results. PHMSA has indicated that they intend for the rules to go into effect in late 2016.

Xcel Energy has been taking actions that were intended to comply with the Pipeline Safety Act and any related PHMSA regulations as they become effective. PSCo and NSP-Minnesota can generally recover costs to comply with the transmission and distribution integrity management programs through the PSIA and GUIC riders, respectively.

FERC

The FERC has jurisdiction over rates for electric transmission service in interstate commerce and electricity sold at wholesale, hydro facility licensing, natural gas transportation, asset transactions and mergers, accounting practices and certain other activities of Xcel Energy Inc.’s utility subsidiaries and transmission-only subsidiaries, including enforcement of North American Electric Reliability Corporation mandatory electric reliability standards. State and local agencies have jurisdiction over many of Xcel Energy Inc.’s utility subsidiaries’ activities, including regulation of retail rates and environmental matters. See additional discussion in the summary of recent federal regulatory developments and public utility regulation sections of the Xcel Energy Inc. Annual Report on Form 10-K for the year ended Dec. 31, ~~2015~~2016 and Quarterly Report on Form 10-Q for the quarterly period ended March 31, ~~2016.~~2017. In addition to the matters discussed below, see Note 5 to the consolidated financial statements for a discussion of other regulatory matters.

Status of FERC ~~Order, New~~Commissioners — The FERC is normally comprised of five commissioners appointed by the President and confirmed by the Senate. There is currently only one sitting commissioner. Without three commissioners, the FERC does not have a quorum to act on contested matters. The lack of a quorum could affect the timing of FERC decisions on proposed rules or pending, newly submitted and future filings involving, among other things, contested electric rate matters and CPCNs for construction of interstate natural gas pipeline facilities to serve the utility subsidiaries. Xcel Energy does not expect any disruption in operations or material delay in decisions on contested matters pending before the FERC. President Trump has submitted nominations to fill three of the vacant seats and has indicated his intent to submit one additional nomination. The three submitted nominations are pending confirmation by the full Senate.

~~SPS Asset Transfer~~Public Utility Regulatory Policies Act (PURPA) Enforcement Complaint against CPUC —In December 2016, Sustainable Power Group, LLC (sPower) petitioned the FERC to ~~Xcel Energy Southwest Transmission Company, LLC (XEST)~~ —initiate an enforcement action in federal court against the CPUC under PURPA. The petition asserts that a December 2016 CPUC ruling, which indicated that a qualifying facility must be a successful bidder in a PSCo resource acquisition bidding process, violated PURPA and FERC rules. In ~~2015~~January 2017, PSCo filed a motion to intervene and protest, arguing that the FERC should decline the petition. The CPUC filed a similar pleading. sPower has proposed to construct 800 MW of solar generation and 700 MW of wind generation in Colorado and seeks to require PSCo to contract for these resources under PURPA. If sPower were to prevail, PSCo’s ability to select generation resources through ~~early 2016, SPS submitted filings~~competitive bidding would be negatively affected. However, due to a lack of quorum at the FERC, the FERC did not act on that petition within the sixty days contemplated by PURPA. Subsequently sPower filed a complaint for declaratory and injunctive relief in the United States District Court for the District of Colorado (District Court) requesting that the court find the bidding requirement in the CPUC qualifying facility rules to be unlawful. PSCo has intervened in that proceeding and the CPUC has filed a motion to dismiss. In June 2017, the United States Magistrate Judge (Magistrate) issued a recommendation to the ~~FERC, PUCT, NMPRC and Kansas Corporation Commission (KCC) seeking approval~~District Court that sPower’s complaint be dismissed because sPower failed to ~~transfer ownership~~establish that it faced a substantial risk of ~~SPS’ 345 KV transmission assets in Kansas and Oklahoma to XEST at net book value of approximately $103 million.~~harm.

~~Formula Rate Treatment of Accumulated Deferred Income Taxes (ADIT)~~ — In 2015, the MISO TOs, including NSP-Minnesota and NSP-Wisconsin, SPS and PSCo filed separate changes to their transmission formula rates and the PSCo production formula rate to modify the treatment of ADIT to comply with IRS guidance regarding how ADIT must be reflected in formula rates using future test years and a true-up. The filings were intended to ensure that NSP-Minnesota, NSP-Wisconsin, PSCo and SPS are in compliance with IRS rules and may continue to use accelerated tax depreciation.

Golden Spread protested the proposed changes to the SPS transmission formula rate. In December 2015, the FERC partially accepted the proposed NSP-Minnesota and NSP-Wisconsin transmission formula rate changes, but rejected the changes regarding the treatment of ADIT in the formula rate true-up. NSP-Minnesota and NSP-Wisconsin sought clarification or rehearing of the FERC order partially rejecting the NSP System filing. In April 2016, FERC accepted the SPS and PSCo formula rate changes, subject to a compliance filing. SPS and PSCo submitted the compliance filings in May 2016. FERC action on the NSP-Minnesota and NSP-Wisconsin request for clarification remains pending.2018.

Derivatives, Risk Management and Market Risk

Xcel Energy Inc. and its subsidiaries are exposed to a variety of market risks in the normal course of business. Market risk is the potential loss that may occur as a result of adverse changes in the market or fair value of a particular instrument or commodity. All financial and commodity-related instruments, including derivatives, are subject to market risk. See Note 8 to the consolidated financial statements for further discussion of market risks associated with derivatives.

Xcel Energy is exposed to the impact of adverse changes in price for energy and energy-related products, which is partially mitigated by the use of commodity derivatives. In addition to ongoing monitoring and maintaining credit policies intended to minimize overall credit risk, when necessary, management takes steps to mitigate changes in credit and concentration risks associated with its derivatives and other contracts, including parental guarantees and requests of collateral. While Xcel Energy expects that the counterparties will perform under the contracts underlying its derivatives, the contracts expose Xcel Energy to some credit and non-performance risk.

Though no material non-performance risk currently exists with the counterparties to Xcel Energy’s commodity derivative contracts, distress in the financial markets may in the future impact that risk to the extent it impacts those counterparties. Distress in the financial markets may also impact the fair value of the securities in the nuclear decommissioning fund and master pension trust, as well as Xcel Energy’s ability to earn a return on short-term investments of excess cash.

Commodity Price Risk — Xcel Energy Inc.’s utility subsidiaries are exposed to commodity price risk in their electric and natural gas operations. Commodity price risk is managed by entering into long- and short-term physical purchase and sales contracts for electric capacity, energy and energy-related products and for various fuels used in generation and distribution activities. Commodity price risk is also managed through the use of financial derivative instruments. Xcel Energy’s risk management policy allows it to manage commodity price risk within each rate-regulated operation to the extent such exposure exists.

Table of Contents

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 ~~energy-related instruments.~~natural gas-related instruments, including derivatives. Xcel Energy’s risk management policy allows management to conduct these activities within guidelines and limitations as approved by its risk management committee, which is made up of management personnel not directly involved in the activities governed by this policy.

At June 30, 2017, a 10 percent increase in market prices for commodity trading contracts would increase pretax income from continuing operations by approximately $0.3 million, whereas a 10 percent decrease would decrease pretax income from continuing operations by approximately $0.8 million. At June 30, 2016, a 10 percent increase in market prices for commodity trading contracts would increase pretax income from continuing operations by approximately $0.1 million, whereas a 10 percent decrease would decrease pretax income from continuing operations by approximately $0.1 million. At June 30, 2015, a 10 percent increase in market prices for commodity trading contracts would increase pretax income from continuing operations by approximately $0.4 million, whereas a 10 percent decrease would decrease pretax income from continuing operations by approximately $0.4 million.

Xcel Energy Inc.’s 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, ~~including transactions that are not recorded at fair value,~~ 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, calculated on a consolidated basis using a Monte Carlo simulation with a 95 percent confidence level and a one-day holding period, were as follows:


(Millions of Dollars)	Three Months Ended June 30		VaR Limit		Average		High		Low		Three Months Ended June 30		VaR Limit		Average		High		Low

Nuclear Fuel Supply — NSP-Minnesota is scheduled to take delivery of approximately ~~87 percent of its 2016 and approximately~~ 13 percent of its 2017 and approximately 54 percent of its 2018 enriched nuclear material requirements from sources that could be impacted by events in Ukraine and sanctions against Russia. Alternate potential sources are expected to provide the flexibility to manage NSP-Minnesota’s nuclear fuel supply to ensure that plant availability and reliability will not be negatively impacted in the near-term. Long-term, through 2024, NSP-Minnesota is scheduled to take delivery of approximately 3631 percent of its average enriched nuclear material requirements from sources that could be impacted by events in Ukraine and extended sanctions against Russia. NSP-Minnesota is closely following the progression of these events and will periodically assess if further actions are required to assure a secure supply of enriched nuclear material.

Separately, NSP-Minnesota has enriched nuclear fuel materials in process with Westinghouse Electric Corporation (Westinghouse). Westinghouse filed for Chapter 11 bankruptcy protection in March 2017. NSP-Minnesota owns materials in Westinghouse’s inventory and has contracts in place under which Westinghouse will provide certain services during an upcoming outage at PI. Westinghouse has indicated its intention to perform under the arrangements. Based on Westinghouse’s stated intent and the interim financing secured to fund its on-going operations, NSP-Minnesota does not expect the bankruptcy to materially impact 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’s 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, ~~2016~~2017 and ~~2015,~~2016, a 100-basis-point change in the benchmark rate on Xcel Energy’s variable rate debt would impact pretax interest expense annually by approximately ~~$5.9~~$9.4 million and ~~$4.5~~$5.9 million, respectively. See Note 8 to the consolidated financial statements for a discussion of Xcel Energy Inc. and its subsidiaries’ interest rate derivatives.

~~Table of Contents~~

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, ~~2016,~~2017, the fund was invested in a diversified portfolio of cash equivalents, debt securities, equity securities, and other investments. These investments may be used only for activities related to nuclear decommissioning. Given the purpose and legal restrictions on the use of nuclear decommissioning fund assets, 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, including any other-than-temporary impairments, are deferred as a component of the regulatory asset for nuclear decommissioning. Since the accounting for nuclear decommissioning recognizes that costs are recovered through rates, fluctuations in equity prices or interest rates affecting the nuclear decommissioning fund do not have ana direct impact on earnings.

Credit Risk — Xcel Energy Inc. and its subsidiaries are 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 maintain credit policies intended to minimize overall credit risk and actively monitor these policies to reflect changes and scope of operations.

At June 30, 2017, a 10 percent increase in commodity prices would have resulted in an increase in credit exposure of $18.1 million, while a decrease in prices of 10 percent would have resulted in an increase in credit exposure of $2.1 million. At June 30, 2016, a 10 percent increase in commodity prices would have resulted in a decrease in credit exposure of $9.2 million, while a decrease in prices of 10 percent would have resulted in an increase in credit exposure of $16.4 million. At June 30, 2015, a 10 percent increase in commodity prices would have resulted in a decrease in credit exposure of $3.4 million, while a decrease in prices of 10 percent would have resulted in an increase in credit exposure of $4.5 million.

Xcel Energy Inc. and its subsidiaries conduct standard credit reviews for all counterparties. Xcel Energy employs additional credit risk control mechanisms when appropriate, such as letters of credit, parental guarantees, standardized master netting agreements and termination provisions that allow for offsetting of positive and negative exposures. Credit exposure is monitored and, when necessary, the activity with a specific counterparty is limited until credit enhancement is provided. Distress in the financial markets could increase Xcel Energy’s credit risk.

Fair Value Measurements

Xcel Energy follows accounting and disclosure guidance on 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. 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.

Table of Contents

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, 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, ~~2016.~~2017. 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 (OCI) or regulatory assets and liabilities. The 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, ~~2016.~~2017.

Commodity derivative assets and liabilities assigned to Level 3 typically consist of FTRs, as well as forwards and options that are long-term in nature. Level 3 commodity derivative assets and liabilities represent ~~1.5~~3.5 percent and ~~8.5~~9.8 percent of total assets and liabilities, respectively, measured at fair value at June 30, ~~2016.~~2017.

Determining the fair value of FTRs requires numerous management forecasts that vary in observability, including various forward commodity prices, retail and wholesale demand, generation and resulting transmission system congestion. Given the limited observability of management’s forecasts for several of these inputs, these instruments have been assigned a Level 3. Level 3 commodity derivatives assets and liabilities included ~~$28.1~~$68.1 million and ~~$3.6~~$4.0 million of estimated fair values, respectively, for FTRs held at June 30, ~~2016.~~2017.

Determining the fair value of certain commodity forwards and options can require management to make use of subjective price and volatility forecasts which extend to periods beyond those readily observable on active exchanges or quoted by brokers. When less observable forward price and volatility forecasts are significant to determining the value of commodity forwards and options, these instruments are assigned to Level 3. There were ~~immaterial~~$5.2 million in Level 3 commodity ~~forwards~~derivative assets and no liabilities for options held at June 30, ~~2016.~~2017. There were immaterial Level 3 forwards held at June 30, 2017.

Capital Requirements

Xcel Energy expects to meet future financing requirements by periodically issuing short-term debt, long-term debt, common stock, hybrid and other securities to maintain desired capitalization ratios.

Regulation of Derivatives — In July 2010, financial reform legislation was passed that provides for the regulation of derivative transactions amongst other provisions. Provisions within the bill provide the Commodity Futures Trading Commission (CFTC) and the SEC with expanded regulatory authority over derivative and swap transactions. The CFTC ruled that swap dealing activity conducted by entities for the preceding 12 months under a notional limit, initially set at $8 billion, will fall under the general de minimis threshold and will not subject an entity to registering as a swap dealer. The de minimis threshold is scheduled to be reduced to $3 billion in ~~2017.~~2018. Xcel Energy’s current and projected swap activity is well below these de minimis thresholds. The bill also contains provisions that exempt certain derivatives end users from much of the clearing and margin requirements and Xcel Energy’s Board of Directors has renewed the end-user exemption on an annual basis. Xcel Energy is currently meeting all reporting requirements and transaction restrictions.

Southwest Power Pool Inc. (SPP) FTR Margining Requirements — In SPP, the process for TOs involves the receipt of Auction Revenue Rights (ARRs) and, if elected by the TO, conversion of those ARRs to firm FTRs. SPP requires that the TO post collateral for the conversion of ARRs to FTRs. At June 30, 2017, SPS had a $2.5 million letter of credit posted with SPP for the annual FTR auction, which was a reduction from the initial requirement of $15 million.

Pension Fund — Xcel Energy’s pension assets are invested in a diversified portfolio of domestic and international equity securities, short-term to long-duration fixed income securities, and alternative investments, including private equity, real estate, hedge fund of funds and commodity investments.

In January ~~2016,~~2017, contributions of ~~$125.0~~$150.0 million were made across four of Xcel Energy’s pension plans;

In ~~2015,~~2016, contributions of ~~$90.0~~$125.2 million were made across four of Xcel Energy’s pension plans; and

For future years, ~~we anticipate~~ contributions will be made as ~~necessary.~~deemed appropriate based on evaluation of various factors including the funded status of the plans, minimum funding requirements, interest rates and expected investment returns.

Capital Sources

Short-Term Funding Sources — Xcel Energy uses a number of sources to fulfill short-term funding needs, including operating cash flow, notes payable, commercial paper and bank lines of credit. The amount and timing of short-term funding needs depend in large part on financing needs for construction expenditures, working capital and dividend payments.

Short-Term Investments — Xcel Energy Inc., NSP-Minnesota, NSP-Wisconsin, PSCo and SPS maintain cash operating and short-term investment accounts. At June 30, ~~2016,~~2017, approximately ~~$9.1~~$1.8 million of cash was held in these accounts.
