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 , to extend the end of the transition period to December 31, 2024. As of March 31, 2023, the Company has amended the majority of the contracts that previously used LIBOR as a reference rate and elected to apply relief to certain modified cash flow interest rate swap and debt agreements. The adoption did not have a material impact on the Company’s financial statements. The Company intends to amend the remaining contracts that use LIBOR as a reference rate no later than June 30, 2023, the LIBOR cessation date.

Business Combination and Asset Acquisition [Abstract]
Acquisitions and Dispositions	Acquisitions and Dispositions Acquisitions Daggett 3 Drop Down — On February 17, 2023, the Company, through its indirect subsidiary, Daggett Solar Investment LLC, acquired the Class A membership interests in Daggett TargetCo LLC, the indirect owner of the Daggett 3 solar project, a 300 MW solar project with matching storage capacity that is currently under construction, located in San Bernardino, California, from Clearway Renew LLC, a subsidiary of CEG, for cash consideration of $21 million. Simultaneously, a cash equity investor acquired the Class B membership interests in Daggett TargetCo LLC from Clearway Renew LLC for cash consideration of $129 million. The Company and the cash equity investor then contributed their Class A and B membership interests, respectively, into Daggett Renewable Holdco LLC, a partnership between the Company and the cash equity investor, which consolidates Daggett TargetCo LLC. Daggett TargetCo LLC consolidates, as the indirect owner of the primary beneficiary, a tax equity fund, Daggett TE Holdco LLC, which owns the Daggett 3 solar project, as further described in Note 4, Investments Accounted for by the Equity Method and Variable Interest Entities. Daggett 3 has PPAs with investment-grade counterparties that have a 15-year weighted average contract duration that commence when the underlying operating assets reach commercial operations, which is expected to occur for the majority of the operating assets in the second quarter of 2023. The Daggett 3 operations are reflected in the Company’s Renewables segment and the acquisition was funded with existing sources of liquidity. The acquisition was determined to be an asset acquisition and the Company consolidates Daggett 3 on a prospective basis in its financial statements. The assets and liabilities transferred to the Company relate to interests under common control and were recorded at historical cost in accordance with ASC 805-50, Business Combinations - Related Issues . The difference between the cash paid of $21 million and the historical cost of the Company’s net assets acquired of $15 million was recorded as an adjustment to CEG’s contributed capital balance. In addition, the Company reflected $21 million of the Company’s purchase price, which was contributed back to the Company by CEG to pay down the acquired long-term debt, in the line item contributions from CEG, net of distributions in the consolidated statement of members’ equity. The following is a summary of assets and liabilities transferred in connection with the acquisition as of February 17, 2023: (In millions) Daggett 3 Restricted cash $ 14 Property, plant and equipment 534 Right-of-use-assets, net 31 Derivative assets 27 Total assets acquired 606 Long-term debt (a) 480 Long-term lease liabilities 33 Other current and non-current liabilities (b) 78 Total liabilities assumed 591 Net assets acquired $ 15 (a) Includes a $181 million construction loan, $75 million sponsor equity bridge loan and $229 million tax equity bridge loan, offset by $5 million in unamortized debt issuance costs.

Entities that are Consolidated As further described under Item 15 — Note 5, Investments Accounted for by the Equity Method and Variable Interest Entities, to the consolidated financial statements included in the Company’s 2022 Form 10-K, the Company has a controlling financial interest in certain entities which have been identified as VIEs under ASC 810, Consolidations , or ASC 810. These arrangements are primarily related to tax equity arrangements entered into with third parties in order to monetize certain tax credits associated with wind and solar facilities. The Company also has a controlling financial interest in certain partnership arrangements with third-party investors, which have also been identified as VIEs. Under the Company’s arrangements that have been identified as VIEs, the third-party investors are allocated earnings, tax attributes and distributable cash in accordance with the respective limited liability agreements. Many of these arrangements also provide a mechanism to facilitate achievement of the investor’s specified return by providing incremental cash distributions to the investor at a specified date if the specified return has not yet been achieved. The discussion below describes material changes to VIEs during the three months ended March 31, 2023. Daggett Renewable Holdco LLC — As described in Note 3, Acquisitions and Dispositions , on February 17, 2023, Daggett Solar Investment LLC, an indirect subsidiary of the Company, acquired the Class A membership interests in Daggett TargetCo LLC while a cash equity investor acquired the Class B membership interests.

The Company consolidates Daggett Renewable Holdco LLC as a VIE as the Company is the primary beneficiary, through its role as managing member. The Company recorded the noncontrolling interest of the cash equity investor in Daggett Renewable Holdco LLC at historical carrying amount, with the offset to contributed capital. Daggett TargetCo LLC consolidates, as the indirect owner of the primary beneficiary, a tax equity fund, Daggett TE Holdco LLC, which owns the Daggett 3 solar project.

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, 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 March 31, 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) 7,197 6,760 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 March 31, 2023 As of December 31, 2022 Level 2 Level 3 Level 2 Level 3 (In millions) Long-term debt, including current portion $ 1,904 $ 4,858 $ 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 March 31, 2023 As of December 31, 2022 Fair Value (a) Fair Value (a) (In millions) Level 2 Level 3 Level 2 Level 3 Derivative assets: Interest rate contracts $ 91 $ — $ 89 $ — Other financial instruments (b) — 18 — 17 Total assets $ 91 $ 18 $ 89 $ 17 Derivative liabilities: Commodity contracts $ — $ 334 $ — $ 353 Interest rate contracts 1 — — — Total liabilities $ 1 $ 334 $ — $ 353 (a) There were no derivative assets classified as Level 1 or Level 3 and no liabilities classified as Level 1 as of March 31, 2023 and December 31, 2022. (b) Includes SREC contract. The following table reconciles the beginning and ending balances for instruments that are recognized at fair value in the consolidated financial statements using significant unobservable inputs: Three months ended March 31, 2023 2022 (In millions) Fair Value Measurement Using Significant Unobservable Inputs (Level 3) Beginning balance $ (336) $ (154) Settlements 4 6 Additions due to loss of NPNS exception — (21) Total gains (losses) for the period included in earnings 16 (111) Ending balance $ (316) $ (280) Change in unrealized gains included in earnings for derivatives and other financial instruments held as of March 31, 2023 $ 16 Derivative and Financial Instruments Fair Value Measurements The Company's contracts are non-exchange-traded and valued using prices provided by external sources. 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 March 31, 2023, contracts valued with prices provided by models and other valuation techniques make up 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: March 31, 2023 Fair Value Input/Range Assets Liabilities Valuation Technique Significant Unobservable Input Low High Weighted Average (In millions) Commodity Contracts $ — $ (334) Discounted Cash Flow Forward Market Price (per MWh) $ 20.81 $ 80.18 $ 39.87 Other Financial Instruments 18 — Discounted Cash Flow Forecast annual generation levels of certain DG solar facilities 58,539 MWh 117,078 MWh 112,897 MWh The following table provides the impact on the fair value measurements to increases/(decreases) in significant unobservable inputs as of March 31, 2023: Significant Unobservable Input Position Change In Input Impact on Fair Value Measurement Forward Market Price Power Sell Increase/(Decrease) Lower/(Higher) Forecast Generation Levels 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 March 31, 2023, the non-performance reserve was a $35 million gain recorded primarily to total operating revenues in the consolidated statements of operations. 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. Counterparty credit exposure includes credit risk exposure under certain long-term agreements, including solar and other PPAs. As external sources or observable market quotes are not available to estimate such exposure, the Company estimates the exposure related to these contracts based on various techniques including, but not limited to, internal models based on a fundamental analysis of the market and extrapolation of observable market data with similar characteristics. A significant portion of these commodity contracts are with utilities with strong credit quality and public utility commission or other regulatory support. However, such regulated utility counterparties can be impacted by changes in government regulations or adverse financial conditions, which the Company is unable to predict. Certain subsidiaries of the Company sell the output of their facilities to PG&E, a significant counterparty of the Company, under long-term PPAs, and PG&E’s credit rating is below investment-grade.

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 is expected to proceed to trial in October 2023. Buckthorn Westex believes the allegations of Georgetown are meritless, and Buckthorn Westex is vigorously defending its rights under the PPA.

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 , to extend the end of the transition period to December 31, 2024. As of March 31, 2023, the Company has amended the majority of the contracts that previously used LIBOR as a reference rate and elected to apply relief to certain modified cash flow interest rate swap and debt agreements. The adoption did not have a material impact on the Company’s financial statements. The Company intends to amend the remaining contracts that use LIBOR as a reference rate no later than June 30, 2023, the LIBOR cessation date.
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. Counterparty credit exposure includes credit risk exposure under certain long-term agreements, including solar and other PPAs. As external sources or observable market quotes are not available to estimate such exposure, the Company estimates the exposure related to these contracts based on various techniques including, but not limited to, internal models based on a fundamental analysis of the market and extrapolation of observable market data with similar characteristics. A significant portion of these commodity contracts are with utilities with strong credit quality and public utility commission or other regulatory support. However, such regulated utility counterparties can be impacted by changes in government regulations or adverse financial conditions, which the Company is unable to predict. Certain subsidiaries of the Company sell the output of their facilities to PG&E, a significant counterparty of the Company, under long-term PPAs, and PG&E’s credit rating is below investment-grade.
