Cedar Creek Wind Holdco LLC consolidates as primary beneficiary, Cedar Creek TE Holdco LLC, a tax equity fund that owns the Cedar Creek wind facility. Also on April 16, 2024, a tax equity investor contributed $108 million to acquire the Class A membership interests in Cedar Creek TE Holdco LLC. Cedar Creek has a 25-year PPA with an investment-grade utility that commenced in March 2024. The acquisition was funded with existing sources of liquidity.

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 2023 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, solar and BESS facilities. The Company also has a controlling financial interest in certain partnership arrangements with third-party investors, which also have 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 company 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 following is a summary of significant activity during the three months ended March 31, 2024 related to the Company’s consolidated VIEs: Lighthouse Renewable Holdco 2 LLC As described in Note 3, Acquisitions , on March 15, 2024, TSN1 TE Holdco LLC, an indirect subsidiary of the Company, acquired Texas Solar Nova 2, LLC.

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 amount and estimated fair value of the Company’s recorded financial instrument not carried at fair market value or that does not approximate fair value is as follows: As of March 31, 2024 As of December 31, 2023 Carrying Amount Fair Value Carrying Amount Fair Value (In millions) Long-term debt, including current portion (a) $ 8,204 $ 7,631 $ 8,102 $ 7,611 (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, 2024 As of December 31, 2023 Level 2 Level 3 Level 2 Level 3 (In millions) Long-term debt, including current portion $ 1,889 $ 5,742 $ 1,939 $ 5,672 Recurring Fair Value Measurements The Company records its derivative assets and liabilities at fair market value on its consolidated balance sheets.

(b) The Company’s interest rate swaps are measured at fair value using an income approach, which uses readily observable inputs, such as forward interest rates (e.g., SOFR) and contractual terms to estimate fair value. (c) Includes long-term backbone transportation service contracts classified as Level 2 and short-term heat rate call option contracts classified as Level 3. (d) Includes SREC contract. (e) As of March 31, 2024 and December 31, 2023, amounts include $361 million and $325 million related to long-term power commodity contracts and zero and $5 million related to short-term heat rate call option contracts, respectively. 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, 2024 2023 (In millions) Fair Value Measurement Using Significant Unobservable Inputs (Level 3) Beginning balance $ (317) $ (336) Settlements (1) 4 Total (losses) gains for the period included in earnings (21) 16 Ending balance $ (339) $ (316) Change in unrealized losses included in earnings for derivatives and other financial instruments held as of March 31, 2024 $ (21) 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 energy-related commodity contracts, which includes long-term power commodity contracts and heat rate call option 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, 2024, contracts valued with prices provided by models and other valuation techniques make up 6% of derivative assets and 100% of derivative liabilities and other financial instruments. The Company’s significant positions classified as Level 3 include physical and financial energy-related 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, 2024 Fair Value Input/Range Assets Liabilities Valuation Technique Significant Unobservable Input Low High Weighted Average (In millions) Long-term Power Commodity Contracts $ — $ 361 Discounted Cash Flow Forward Market Price (per MWh) $ 19.73 $ 86.87 $ 43.47 Heat Rate Call Option Commodity Contracts 8 — Option Model Forward Market Price (per MWh) $ (28.22) $ 1,321.77 $ 53.33 Option Model Forward Market Price (per MMBtu) $ 1.15 $ 14.51 $ 5.52 Other Financial Instruments 14 — 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 March 31, 2024: 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) Energy-Related Commodity Contracts Forward Market Price Gas Sell Increase/(Decrease) Higher/(Lower) Other Financial Instruments 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, 2024, the non-performance reserve was a $12 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 2023 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.

Earnings Per Share [Abstract]
Loss Per Share	Loss Per Share Basic loss per common share is computed by dividing net income (loss) by the weighted average number of common shares outstanding. Shares issued during the year are weighted for the portion of the year that they were outstanding. Diluted loss per share is computed in a manner consistent with that of basic losses per share while giving effect to all potentially dilutive common shares that were outstanding during the period. The reconciliation of the Company’s basic and diluted loss per share is shown in the following table: Three months ended March 31, 2024 2023 (In millions, except per share data) (a) Common Class A Common Class C Common Class A Common Class C Basic and diluted loss per share attributable to Clearway Energy, Inc. common stockholders Net loss attributable to Clearway Energy, Inc. $ (1) $ (1) $ — $ — Weighted average number of common shares outstanding — basic and diluted 35 82 35 82 Loss per weighted average common share — basic and diluted $ (0.02) $ (0.02) $ — $ — (a) Net loss attributable to Clearway Energy, Inc. and basic and diluted loss per share might not recalculate due to presenting amounts in millions rather than whole dollars.

Income Taxes	Income Taxes Effective Tax Rate The income tax provision consisted of the following amounts: Three months ended March 31, 2024 2023 (In millions, except percentages) Loss before income taxes $ (59) $ (52) Income tax benefit (13) (12) Effective income tax rate 22.0 % 23.1 % For each of the three months ended March 31, 2024 and 2023, the overall effective tax rate was different than the statutory rate of 21% primarily due to the allocation of taxable earnings and losses based on the partners’ interest in Clearway Energy LLC, which includes the effects of applying the HLBV method of accounting for book purposes for certain partnerships. For tax purposes, Clearway Energy LLC is treated as a partnership; therefore, the Company and CEG each record their respective share of taxable income or loss.

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 2023 Form 10-K. Interim results are not necessarily indicative of results for a full year. In the opinion of management, the accompanying unaudited interim consolidated financial statements contain all material adjustments consisting of normal and recurring accruals necessary to present fairly the Company’s consolidated financial position as of March 31, 2024, and results of operations, comprehensive loss and cash flows for the three months ended March 31, 2024 and 2023.
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, Cash Equivalents and Restricted Cash
Restricted Cash	Restricted cash consists primarily of funds held to satisfy the requirements of certain debt agreements and funds held within the Company’s facilities that are restricted in their use.
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 2023 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 energy-related 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.
