Fair Value of Financial Instrum

Fair Value of Financial Instruments	9 Months Ended

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments Fair Value Accounting under ASC 820 ASC 820 establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three levels as follows: • Level 1—quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access as of the measurement date. • Level 2—inputs other than quoted prices included within Level 1 that are directly observable for the asset or liability or indirectly observable through corroboration with observable market data. • Level 3—unobservable inputs for the asset or liability only used when there is little, if any, market activity for the asset or liability at the measurement date. In accordance with ASC 820, the Company determines the level in the fair value hierarchy within which each fair value measurement in its entirety falls, based on the lowest level input that is significant to the fair value measurement. For cash and cash equivalents, restricted cash, accounts receivable — trade, note receivable — affiliate, accounts payable — trade, accounts payable — affiliates and accrued expenses and other current liabilities, the carrying amounts approximate fair value because of the short-term maturity of those instruments and are classified as Level 1 within the fair value hierarchy. The carrying amounts and estimated fair values of the Company’s recorded financial instruments not carried at fair market value or that do not approximate fair value are as follows: As of September 30, 2023 As of December 31, 2022 Carrying Amount Fair Value Carrying Amount Fair Value (In millions) Long-term debt, including current portion — affiliate $ 2 $ 2 $ 2 $ 2 Long-term debt, including current portion — external (a) 7,581 6,527 6,874 6,288 (a) Excludes net debt issuance costs, which are recorded as a reduction to long-term debt on the Company’s consolidated balance sheets. The fair value of the Company’s publicly-traded long-term debt is based on quoted market prices and is classified as Level 2 within the fair value hierarchy. The fair value of debt securities, non-publicly traded long-term debt and certain notes receivable of the Company are based on expected future cash flows discounted at market interest rates, or current interest rates for similar instruments with equivalent credit quality and are classified as Level 3 within the fair value hierarchy. The following table presents the level within the fair value hierarchy for long-term debt, including current portion: As of September 30, 2023 As of December 31, 2022 Level 2 Level 3 Level 2 Level 3 (In millions) Long-term debt, including current portion $ 1,762 $ 4,767 $ 1,836 $ 4,454 Recurring Fair Value Measurements The Company records its derivative assets and liabilities at fair market value on its consolidated balance sheet. The following table presents assets and liabilities measured and recorded at fair value on the Company’s consolidated balance sheets on a recurring basis and their level within the fair value hierarchy: As of September 30, 2023 As of December 31, 2022 Fair Value (a) Fair Value (a) (In millions) Level 2 Level 3 Level 2 Level 3 Derivative assets: Commodity contracts (b) $ — $ 3 $ — $ — Interest rate contracts 180 — 89 — Other financial instruments (c) — 13 — 17 Total assets $ 180 $ 16 $ 89 $ 17 Derivative liabilities: Commodity contracts $ — $ 325 $ — $ 353 Total liabilities $ — $ 325 $ — $ 353 (a) There were no derivative assets classified as Level 1 or Level 3 and no liabilities classified as Level 1 as of September 30, 2023 and December 31, 2022.

The Company uses quoted observable forward prices to value its commodity contracts. To the extent that observable forward prices are not available, the quoted prices reflect the average of the forward prices from the prior year, adjusted for inflation. As of September 30, 2023, contracts valued with prices provided by models and other valuation techniques make up 2% of derivative assets and 100% of derivative liabilities and other financial instruments. The Company’s significant positions classified as Level 3 include physical commodity contracts executed in illiquid markets. The significant unobservable inputs used in developing fair value include illiquid power tenors and location pricing, which is derived by extrapolating pricing as a basis to liquid locations. The tenor pricing and basis spread are based on observable market data when available or derived from historic prices and forward market prices from similar observable markets when not available. The following table quantifies the significant unobservable inputs used in developing the fair value of the Company’s Level 3 positions: September 30, 2023 Fair Value Input/Range Assets Liabilities Valuation Technique Significant Unobservable Input Low High Weighted Average (In millions) Energy-Related Commodity Contracts $ — $ (325) Discounted Cash Flow Forward Market Price (per MWh) $ 21.75 $ 72.15 $ 38.96 Heat Rate Call Option Commodity Contracts 3 — Option Model Forward Market Price (per MWh) $ 6.24 $ 179.30 $ 67.93 Option Model Forward Market Price (per MMBtu) $ 2.79 $ 15.42 $ 6.30 Other Financial Instruments 13 — Discounted Cash Flow Forecast annual generation levels of certain DG solar facilities 60,801 MWh 121,602 MWh 115,622 MWh The following table provides the impact on the fair value measurements to increases/(decreases) in significant unobservable inputs as of September 30, 2023: Type Significant Unobservable Input Position Change In Input Impact on Fair Value Measurement Energy-Related Commodity Contracts Forward Market Price Power Sell Increase/(Decrease) Lower/(Higher) Other Financial Instruments Forecast Generation Levels Sell Increase/(Decrease) Higher/(Lower) Heat Rate Call Option Commodity Contracts Forward Market Power Price Sell Increase/(Decrease) Lower/(Higher) Heat Rate Call Option Commodity Contracts Forward Market Gas Price Sell Increase/(Decrease) Higher/(Lower) The fair value of each contract is discounted using a risk-free interest rate. In addition, a credit reserve is applied to reflect credit risk, which is, for interest rate swaps, calculated based on credit default swaps using the bilateral method. For commodities, to the extent that the Net Exposure under a specific master agreement is an asset, the Company uses the counterparty’s default swap rate. If the Net Exposure under a specific master agreement is a liability, the Company uses a proxy of its own default swap rate. For interest rate swaps and commodities, the credit reserve is added to the discounted fair value to reflect the exit price that a market participant would be willing to receive to assume the liabilities or that a market participant would be willing to pay for the assets. As of September 30, 2023, the non-performance reserve was a $6 million gain recorded primarily to total operating revenues in the consolidated statements of income. It is possible that future market prices could vary from those used in recording assets and liabilities and such variations could be material. Concentration of Credit Risk In addition to the credit risk discussion as disclosed under Item 15 — Note 2, Summary of Significant Accounting Policies , to the consolidated financial statements included in the Company’s 2022 Form 10-K, the following item is a discussion of the concentration of credit risk for the Company’s financial instruments. Credit risk relates to the risk of loss resulting from non-performance or non-payment by counterparties pursuant to the terms of their contractual obligations. The Company monitors and manages credit risk through credit policies that include: (i) an established credit approval process; (ii) monitoring of counterparties' credit limits on an as needed basis; (iii) as applicable, the use of credit mitigation measures such as margin, collateral, prepayment arrangements, or volumetric limits; (iv) the use of payment netting agreements; and (v) the use of master netting agreements that allow for the netting of positive and negative exposures of various contracts associated with a single counterparty. Risks surrounding counterparty performance and credit could ultimately impact the amount and timing of expected cash flows. The Company seeks to mitigate counterparty risk by having a diversified portfolio of counterparties.

Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies This note should be read in conjunction with the complete description under Item 15 — Note 14, Commitments and Contingencies , to the consolidated financial statements included in the Company’s 2022 Form 10-K. The Company’s material legal proceeding is described below. The Company believes that it has a valid defense to this legal proceeding and intends to defend it vigorously. The Company records reserves for estimated losses from contingencies when information available indicates that a loss is probable and the amount of the loss, or range of loss, can be reasonably estimated. As applicable, the Company has established an adequate reserve for the matter discussed below. In addition, legal costs are expensed as incurred. Management assesses such matters based on current information and makes a judgment concerning its potential outcome, considering the nature of the claim, the amount and nature of damages sought, and the probability of success. The Company is unable to predict the outcome of the legal proceeding below or reasonably estimate the scope or amount of any associated costs and potential liabilities. As additional information becomes available, management adjusts its assessment and estimate of such contingency accordingly. Because litigation is subject to inherent uncertainties and unfavorable rulings or developments, it is possible that the ultimate resolution of the Company’s liabilities and contingencies could be at amounts that are different from its currently recorded reserves and that such difference could be material. In addition to the legal proceeding noted below, the Company and its subsidiaries are party to other litigation or legal proceedings arising in the ordinary course of business. In management’s opinion, the disposition of these ordinary course matters will not materially adversely affect the Company’s consolidated financial position, results of operations, or cash flows. Buckthorn Solar Litigation On October 8, 2019, the City of Georgetown, Texas, or Georgetown, filed a petition in the District Court of Williamson County, Texas naming Buckthorn Westex, LLC, the Company’s subsidiary that owns the Buckthorn Westex solar project, as the defendant, alleging fraud by nondisclosure and breach of contract in connection with the project and the PPA, and seeking (i) rescission and/or cancellation of the PPA, (ii) declaratory judgment that the alleged breaches constitute an event of default under the PPA entitling Georgetown to terminate, and (iii) recovery of all damages, costs of court, and attorneys’ fees. On November 15, 2019, Buckthorn Westex filed an original answer and counterclaims (i) denying Georgetown’s claims, (ii) alleging Georgetown has breached its contracts with Buckthorn Westex by failing to pay amounts due, and (iii) seeking relief in the form of (x) declaratory judgment that Georgetown’s alleged failure to pay amounts due constitute breaches of and an event of default under the PPA and that Buckthorn did not commit any events of default under the PPA, (y) recovery of costs, expenses, interest, and attorneys’ fees, and (z) such other relief to which it is entitled at law or in equity. In response to motions for partial summary judgment filed by each party, the court denied Georgetown’s motion in its entirety, granted Buckthorn Westex’s motion with respect to the fraud by nondisclosure claim and denied Buckthorn Westex’s motion with respect to the breach of contract claim. The case was scheduled to proceed to trial in October 2023, but the parties agreed to delay the trial date in light of ongoing settlement negotiations. Buckthorn Westex believes the allegations of Georgetown are meritless, and Buckthorn Westex is vigorously defending its rights under the PPA.

	Sep. 30, 2023
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited interim consolidated financial statements have been prepared in accordance with the SEC’s regulations for interim financial information and with the instructions to Form 10-Q. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. The following notes should be read in conjunction with the accounting policies and other disclosures as set forth in the notes to the consolidated financial statements included in the Company’s 2022 Form 10-K. Interim results are not necessarily indicative of results for a full year.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions. These estimates and assumptions impact the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as of the date of the consolidated financial statements. They also impact the reported amounts of net earnings during the reporting periods. Actual results could be different from these estimates.
Cash and Cash Equivalents	Cash and cash equivalents include highly liquid investments with an original maturity of three months or less at the time of purchase.
Restricted Cash	Restricted cash consists primarily of funds held to satisfy the requirements of certain debt agreements and funds held within the Company’s projects that are restricted in their use.
Recently Adopted Accounting Standards	Recently Adopted Accounting Standards In March 2020, the FASB issued ASU No. 2020-4, Facilitation of the Effects of Reference Rate Reform on Financial Reporting . The amendments provide for optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions affected by reference rate reform if certain criteria are met. These amendments apply only to contracts that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform, which affects certain of the Company’s debt and interest rate swap agreements. The guidance is effective for all entities as of March 20, 2020 through December 31, 2022. In December 2022, the FASB issued ASU No. 2022-6, Deferral of the Sunset Date of Reference Rate Reform
Concentration of Credit Risk	Concentration of Credit Risk In addition to the credit risk discussion as disclosed under Item 15 — Note 2, Summary of Significant Accounting Policies , to the consolidated financial statements included in the Company’s 2022 Form 10-K, the following item is a discussion of the concentration of credit risk for the Company’s financial instruments. Credit risk relates to the risk of loss resulting from non-performance or non-payment by counterparties pursuant to the terms of their contractual obligations. The Company monitors and manages credit risk through credit policies that include: (i) an established credit approval process; (ii) monitoring of counterparties' credit limits on an as needed basis; (iii) as applicable, the use of credit mitigation measures such as margin, collateral, prepayment arrangements, or volumetric limits; (iv) the use of payment netting agreements; and (v) the use of master netting agreements that allow for the netting of positive and negative exposures of various contracts associated with a single counterparty. Risks surrounding counterparty performance and credit could ultimately impact the amount and timing of expected cash flows. The Company seeks to mitigate counterparty risk by having a diversified portfolio of counterparties.
