Fair Value Disclosures [Abstract]
FAIR VALUE	FAIR VALUE The fair value of current financial assets and liabilities, debt service reserves, and other deposits approximate their reported carrying amounts. The estimated fair values of the Company’s assets and liabilities have been determined using available market information. Because these amounts are estimates and based on hypothetical transactions to sell assets or transfer liabilities, the use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts. For further information on our valuation techniques and policies, see Note 5— Fair Value in Item 8.— Financial Statements and Supplementary Data of our 2023 Form 10-K. Recurring Measurements The following table presents, by level within the fair value hierarchy, the Company’s financial assets and liabilities that were measured at fair value on a recurring basis as of the dates indicated (in millions). For the Company’s investments in marketable debt securities, the security classes presented were determined based on the nature and risk of the security and are consistent with how the Company manages, monitors, and measures its marketable securities: March 31, 2024 December 31, 2023 Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Assets DEBT SECURITIES: Available-for-sale: Certificates of deposit $ — $ 338 $ — $ 338 $ — $ 360 $ — $ 360 Government debt securities — 3 — 3 — — — — Total debt securities — 341 — 341 — 360 — 360 EQUITY SECURITIES: Mutual funds 49 — — 49 46 — — 46 Common stock 5 — — 5 — — — — Total equity securities 54 — — 54 46 — — 46 DERIVATIVES: Interest rate derivatives — 268 — 268 — 182 2 184 Foreign currency derivatives — 13 64 77 — 15 59 74 Commodity derivatives — 253 — 253 — 127 1 128 Total derivatives — assets — 534 64 598 — 324 62 386 TOTAL ASSETS $ 54 $ 875 $ 64 $ 993 $ 46 $ 684 $ 62 $ 792 Liabilities Contingent consideration $ — $ — $ 158 $ 158 $ — $ — $ 165 $ 165 DERIVATIVES: Interest rate derivatives — 33 2 35 — 102 6 108 Cross-currency derivatives — 54 — 54 — 63 — 63 Foreign currency derivatives — 28 — 28 — 19 — 19 Commodity derivatives — 191 79 270 — 145 111 256 Total derivatives — liabilities — 306 81 387 — 329 117 446 TOTAL LIABILITIES $ — $ 306 $ 239 $ 545 $ — $ 329 $ 282 $ 611 As of March 31, 2024, all available-for-sale debt securities had stated maturities within one year. There were no other-than-temporary impairments of marketable securities during the three months ended March 31, 2024. The level 3 contingent consideration relates mainly to the acquisition of Bellefield in June 2023. Credit-related impairments are recognized in earnings under ASC 326. Gains and losses on the sale of investments are determined using the specific-identification method.

For the CAISO Energy Swap, increases in the estimate above would decrease the value of the derivative. Contingent consideration is primarily related to future milestone payments associated with acquisitions of renewables development projects. The estimated fair value of contingent consideration is determined using probability-weighted discounted cash flows based on internal forecasts, which are considered Level 3 inputs. Changes in Level 3 inputs, particularly changes in the probability of achieving development milestones, could result in material changes to the fair value of the contingent consideration and could materially impact the amount of expense or income recorded each reporting period. Contingent consideration is updated quarterly with any prospective changes in fair value recorded through earnings. Nonrecurring Measurements The Company measures fair value using the applicable fair value measurement guidance. Impairment expense, shown as pre-tax loss below, is measured by comparing the fair value at the evaluation date to the then-latest available carrying amount and is included in Asset impairment expense on the Condensed Consolidated Statements of Operations. The following table summarizes our major categories of asset groups measured at fair value on a nonrecurring basis and their level within the fair value hierarchy (in millions): Measurement Date Carrying Amount (1) Fair Value Pre-tax Loss Three Months Ended March 31, 2024 Level 1 Level 2 Level 3 Held-for-sale businesses: (2) Mong Duong 3/31/2024 $ 450 $ — $ 413 $ — $ 37 Measurement Date Carrying Amount (1) Fair Value Three Months Ended March 31, 2023 Level 1 Level 2 Level 3 Pre-tax Loss Held-for-sale businesses: (2) Jordan (3) 3/31/2023 $ 179 $ — $ 170 $ — $ 14 _____________________________ (1) Represents the carrying values of the asset groups at the dates of measurement, before fair value adjustment.

FAIR VALUE	FAIR VALUE The fair value of current financial assets and liabilities, debt service reserves, and other deposits approximate their reported carrying amounts. The estimated fair values of the Company’s assets and liabilities have been determined using available market information. Because these amounts are estimates and based on hypothetical transactions to sell assets or transfer liabilities, the use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts. For further information on our valuation techniques and policies, see Note 5— Fair Value in Item 8.— Financial Statements and Supplementary Data of our 2023 Form 10-K. Recurring Measurements The following table presents, by level within the fair value hierarchy, the Company’s financial assets and liabilities that were measured at fair value on a recurring basis as of the dates indicated (in millions).

For the CAISO Energy Swap, increases in the estimate above would decrease the value of the derivative. Contingent consideration is primarily related to future milestone payments associated with acquisitions of renewables development projects. The estimated fair value of contingent consideration is determined using probability-weighted discounted cash flows based on internal forecasts, which are considered Level 3 inputs. Changes in Level 3 inputs, particularly changes in the probability of achieving development milestones, could result in material changes to the fair value of the contingent consideration and could materially impact the amount of expense or income recorded each reporting period. Contingent consideration is updated quarterly with any prospective changes in fair value recorded through earnings. Nonrecurring Measurements The Company measures fair value using the applicable fair value measurement guidance. Impairment expense, shown as pre-tax loss below, is measured by comparing the fair value at the evaluation date to the then-latest available carrying amount and is included in Asset impairment expense on the Condensed Consolidated Statements of Operations.

Receivables [Abstract]
FINANCING RECEIVABLES	FINANCING RECEIVABLES Receivables with contractual maturities of greater than one year are considered financing receivables. The following table presents financing receivables by country as of the dates indicated (in millions): March 31, 2024 December 31, 2023 Gross Receivable Allowance Net Receivable Gross Receivable Allowance Net Receivable U.S. $ 46 $ — $ 46 $ 149 $ — $ 149 Chile 36 — 36 33 — 33 Other 10 — 10 11 — 11 Total $ 92 $ — $ 92 $ 193 $ — $ 193 U.S. — AES has recorded non-current receivables pertaining to the sale of the Redondo Beach land. The anticipated collection period extends beyond March 31, 2025. As of December 31, 2023, a significant financing receivable existed for the Warrior Run PPA termination agreement where $108 million was recorded in Other non-current assets on the Consolidated Balance Sheets. On February 1, 2024, the Company executed an agreement to sell all remaining future cash flows under the termination agreement. At the time of execution, the transaction was considered a sale of future revenue under U.S. GAAP. As of March 31, 2024, the corresponding receivables met the held-for-sale criteria and were classified as Current held-for-sale assets on the Condensed Consolidated Balance Sheets . See Note 14— Revenue and Note 18— Held-For-Sale and Dispositions for further details regarding the Warrior Run PPA termination agreement. Chile — AES Andes has recorded receivables pertaining to revenues recognized on regulated energy contracts that were impacted by the Stabilization Funds created by the Chilean government in October 2019 and August 2022, in conjunction with the Tariff Stabilization Laws. Historically, the government updated the prices for these contracts every six months to reflect the contracts' indexation to exchange rates and commodities prices. The Tariff Stabilization Laws do not allow the pass-through of these contractual indexation updates to customers beyond the pricing in effect at July 1, 2019, until new lower-cost renewables contracts are incorporated to supply regulated contracts. Consequently, costs incurred in excess of the July 1, 2019 price are accumulated and borne by generators. As of March 31, 2024, AES Andes aims to reduce its exposure through the sale of receivables. On August 14, 2023, AES Andes executed an agreement to sell up to $227 million of receivables pursuant to the Stabilization Funds, of which $135 million was sold and collected as of March 31, 2024. Through different agreements and programs, as of March 31, 2024, $20 million of current receivables and $7 million of noncurrent receivables were recorded in Accounts receivable and Other noncurrent assets , respectively. Additionally, $29 million of payment deferrals granted to mining customers as part of our green blend agreements were recorded as financing receivables included in Other noncurrent assets at March 31, 2024.

Equity Method Investments and Joint Ventures Disclosure [Text Block]	INVESTMENTS IN AND ADVANCES TO AFFILIATES Summarized Financial Information — The following table summarizes financial information of the Company’s 50%-or-less-owned affiliates that are accounted for using the equity method (in millions): 50%-or-less Owned Affiliates Three Months Ended March 31, 2024 2023 Revenue $ 517 $ 461 Operating loss (33) (43) Net loss (103) (62) Net loss attributable to affiliates (68) (60) Jordan — In March 2024, the Company completed the sale of approximately 26% ownership interest in Amman East and IPP4 for a sale price of $58 million. After adjusting for dividends received since the execution of the sale and purchase agreement, the Company received a net cash payment of $45 million. After completion of the sale, the Company retained 10% ownership interest in each of the businesses, which are accounted for as equity method investments. See Note 18— Held-for-Sale and Dispositions for further information. Amman East and IPP4 are reported in the Energy Infrastructure SBU reportable segment. Uplight — In February 2024, Uplight acquired AutoGrid, a market leader in the Virtual Power Plant (“VPP”) space, from Schneider Electric. As part of the transaction, Schneider contributed an additional $40 million to Uplight, and Uplight issued approximately 91 million additional common units to Schneider as consideration for the acquisition. No incremental investment was required from AES or any other investor. As a result, AES' 29.41% ownership interest in Uplight was diluted to 24.65%. The transaction was accounted for as a partial disposition in which AES recognized a gain of $52 million in Gain on disposal and sale of business interests . As the Company still does not control but has significant influence over Uplight after the transaction, it continues to be accounted for as an equity method investment and is reported in the New Energy Technologies SBU reportable segment. sPower — In December 2022, the Company agreed to sell 49% of its indirect interest in a portfolio of sPower's operating assets ("OpCo B"). On February 28, 2023, sPower closed on the sale for $196 million. As a result of the transaction, the Company received $98 million in sales proceeds and recorded a pre-tax gain on sale of $5 million, recorded in Gain on disposal and sale of business interests . After the sale, the Company's ownership interest in OpCo B decreased from 50% to approximately 26%. As the Company still does not control but has significant influence over sPower after the transaction, it continues to be accounted for as an equity method investment and is reported in the Renewables SBU reportable segment. Alto Maipo — In May 2022, Alto Maipo emerged from bankruptcy in accordance with Chapter 11 of the U.S. Bankruptcy Code. Alto Maipo, as restructured, is considered a VIE. As the Company lacks the power to make significant decisions, it does not meet the criteria to be considered the primary beneficiary of Alto Maipo and therefore does not consolidate the entity. The Company has elected the fair value option to account for its investment in Alto Maipo as management believes this approach will better reflect the economics of its equity interest. As of March 31, 2024, the fair value is insignificant. Alto Maipo is reported in the Energy Infrastructure SBU reportable segment.

Debt

Debt	3 Months Ended

Debt Disclosure [Abstract]
DEBT	DEBT Recourse Debt AES Clean Energy Development — In March 2023, AES Clean Energy Development Holdings, LLC executed a $500 million bridge loan due in December 2023 and used the proceeds for general corporate purposes. The obligations under the bridge loan were unsecured and fully guaranteed by the Parent Company. The bridge loan was repaid in December 2023. Commercial Paper Program — In March 2023, the Company established a commercial paper program under which the Company may issue unsecured commercial paper notes (the “Notes”) up to a maximum aggregate face amount of $750 million outstanding at any time. The maturities of the Notes may vary but will not exceed 397 days from the date of issuance. The proceeds of the Notes will be used for general corporate purposes. The Notes will be sold on customary terms in the U.S. commercial paper market on a private placement basis. The commercial paper program is backed by the Company's $1.5 billion revolving credit facility, and the Company cannot issue commercial paper in an aggregate amount exceeding the then available capacity under its revolving credit facilities. For the three months ended March 31, 2024, the Company borrowed approximately $10.1 billion and repaid approximately $9.3 billion under the commercial paper program, with average daily outstanding borrowings of $486 million. As of March 31, 2024, the Company had $110 million outstanding drawings under its revolving credit facility, and $719 million outstanding borrowings under the commercial paper program with a weighted average interest rate of 5.97%. The Notes are classified as noncurrent. Non-Recourse Debt During the three months ended March 31, 2024, the Company’s following subsidiaries had significant debt issuances (in millions): Subsidiary Issuances (1) AES Indiana (2) $ 1,050 AES Andes 500 _____________________________ (1) These amounts do not include revolving credit facility activity at the Company’s subsidiaries. (2) Issuances relate to both AES Indiana and its parent company, IPALCO. AES Puerto Rico — On June 1, 2023, AES Puerto Rico was unable to pay principal and interest obligations on its Series A Bond Loans due to insufficient funds resulting from financial difficulties at the business. AES Puerto Rico signed forbearance and standstill agreements with its noteholders in July 2023 because of the insufficiency of funds to meet these obligations. On March 5, 2024, AES Puerto Rico and its noteholders executed a financial restructuring, under which the $156 million (including interest) of 6.625% Series A Bond Loans due 2026 was exchanged for $112 million of 6.625% senior secured bonds due January 2028 and $44 million of preferred shares in AES Puerto Rico. The preferred shares bear interest at 3.125% and contains an option whereby AES may call the preferred shares to be converted into 99.9% of the ordinary shares of AES Puerto Rico between December 30, 2025 and December 30, 2027, or would have the option to settle the preferred shares in cash. The noteholders also provided a $23 million bridge loan due March 2026 bearing interest at prime plus 4%. AES Puerto Rico is required to make mandatory prepayments through cash sweeps based on excess cash (as defined in the loan agreements) available from operations on the bridge loan, senior secured bonds, and preferred shares interest. The financial restructuring was accounted for as a troubled debt restructuring in accordance with ASC 470-60, “ Troubled Debt Restructurings by Debtors” as AES Puerto Rico was experiencing financial difficulties and the lenders granted a concession. No gain was recognized for the three months ended March 31, 2024 as a result of this transaction. As of March 31, 2024, cash settlement of the preferred shares is contingent, as the amounts would not be required to be settled in cash if the option to settle the preferred shares with common shares is exercised. AES Indiana — In March 2024, AES Indiana issued $650 million aggregate principal of 5.70% First Mortgage Bonds due April 2054. The net proceeds from this issuance were used to repay existing indebtedness, including its unsecured $300 million term loan due in November 2024 and amounts outstanding under its $350 million revolving credit agreement maturing in December 2027, and for general corporate purposes. In March 2024, IPALCO issued $400 million aggregate principal of 5.75% senior secured notes due April 2034. In April 2024, the net proceeds from this issuance, together with cash on hand, were used to redeem the outstanding $405 million in 3.70% senior secured notes due in September 2024. AES Andes — In March 2024, AES Andes issued $500 million aggregate principal of 6.30% senior unsecured notes due in 2029. The net proceeds from the issuance were used to purchase via tender offer $100 million and $43 million aggregate principal of its senior unsecured notes due in 2079 and 2025, respectively, and repay other existing indebtedness. Netherlands and Colon — In January 2023, AES Hispanola Holdings BV, a Netherlands-based company, and Colon, as co-borrowers, executed a $350 million credit agreement at 8.85%, due in 2028. The Company allocated $300 million and $50 million of the proceeds from the agreement to AES Hispanola Holdings BV and Colon, respectively. The net proceeds from the agreement were used to repay existing indebtedness. As a result of the transaction, the Company recognized a loss on extinguishment of debt of $1 million. AES Clean Energy — In December 2022, AES Clean Energy Development, AES Renewable Holdings, and sPower, an equity method investment, collectively referred to as the Issuers, entered into a Master Indenture agreement whereby long-term notes will be issued from time to time to finance or refinance operating wind, solar, and energy storage projects that are owned by the Issuers. On December 13, 2022, the Issuers entered into the Note Purchase Agreement for the issuance of up to $647 million of 6.55% Senior Notes due in 2047. The notes were sold on December 14, 2022, at par for $647 million. In 2023, the Issuers sold an additional $246 million in 6.37% notes, resulting in aggregate principal amount of notes issued of $884 million. Each of the Issuers is considered a “Co-Issuer” and will be jointly and severally liable with each other Co-Issuer for all obligations under the facility. As of March 31, 2024, the aggregate carrying amount of the notes attributable to AES Clean Energy Development and AES Renewable Holdings was $252 million. In 2021, AES Clean Energy Development, AES Renewable Holdings, and sPower, collectively referred to as the Borrowers, executed two Credit Agreements with aggregate commitments of $1.2 billion and maturity dates in December 2024 and September 2025. The Borrowers executed amendments to the revolving credit facilities, which resulted in an aggregate increase in the commitments of $2.6 billion, bringing the total commitments under the new agreements to $3.8 billion. Under a 2023 amendment, the maturity date of one of the Credit Agreements was extended from December 2024 to May 2026. Each of the Borrowers is considered a “Co-Borrower” and will be jointly and severally liable with each other Co-Borrower for all obligations under the facilities. As a result of increases in commitments used, AES Clean Energy Development and AES Renewable Holdings recorded, in aggregate, an increase in liabilities of $547 million in 2024, resulting in total commitments used under the revolving credit facilities, as of March 31, 2024, of $2.8 billion. As of March 31, 2024, the aggregate commitments used under the revolving credit facilities for the Co-Borrowers was $3.4 billion. Non-Recourse Debt Covenants, Restrictions, and Defaults — The terms of the Company's non-recourse debt include certain financial and nonfinancial covenants. These covenants are limited to subsidiary activity and vary among the subsidiaries. These covenants may include, but are not limited to, maintenance of certain reserves and financial ratios, minimum levels of working capital, and limitations on incurring additional indebtedness. As of March 31, 2024 and December 31, 2023, approximately $363 million and $341 million, respectively, of restricted cash was maintained in accordance with certain covenants of the non-recourse debt agreements. These amounts were included within Restricted cash and Debt service reserves and other deposits in the accompanying Condensed Consolidated Balance Sheets. As of March 31, 2024 and December 31, 2023, approximately $90 million of the restricted cash balances were for collateral held to cover potential liability for current and future insurance claims being assumed by AGIC, AES' captive insurance company. Various lender and governmental provisions restrict the ability of certain of the Company's subsidiaries to transfer their net assets to the Parent Company. Such restricted net assets of subsidiaries amounted to approximately $1.1 billion at March 31, 2024. The following table summarizes the Company’s subsidiary non-recourse debt in default (in millions) as of March 31, 2024. Due to the defaults, these amounts are included in the current portion of non-recourse debt unless otherwise indicated: Subsidiary Primary Nature of Default Debt in Default Net Assets AES Mexico Generation Holdings (TEG and TEP) Covenant $ 143 $ 29 AES Ilumina (Puerto Rico) Covenant 24 29 AES Jordan Solar Covenant 7 11 Total $ 174 None of the defaults are payment defaults, but are instead technical defaults triggered by failure to comply with covenants or other requirements contained in the non-recourse debt documents of the applicable subsidiary. The AES Corporation’s recourse debt agreements include cross-default clauses that will trigger if a subsidiary provides 20% or more of the Parent Company’s total cash distributions from businesses for the four most recently completed fiscal quarters and has an outstanding principal in excess of $200 million in default. As of March 31, 2024, the Company’s subsidiaries had no defaults which resulted in a cross-default under the recourse debt of the Parent Company. In the event the Parent Company is not in compliance with the financial covenants of its revolving credit facility, restricted payments will be limited to regular quarterly shareholder dividends at the then-prevailing rate. Payment defaults and bankruptcy defaults would preclude the making of any restricted payments.

Commitments and Contingencies Disclosure [Abstract]
CONTINGENCIES AND COMMITMENTS	COMMITMENTS AND CONTINGENCIES Parent Guarantees, Letters of Credit, and Commitments — In connection with certain project financings (including tax equity transactions), acquisitions and dispositions, power purchases, EPC contracts, and other agreements, the Parent Company has expressly undertaken limited obligations and commitments, most of which will only be effective or will be terminated upon the occurrence of future events. In the normal course of business, the Parent Company has entered into various agreements, mainly guarantees and letters of credit, to provide financial or performance assurance to third parties on behalf of AES businesses. These agreements are entered into primarily to support or enhance the creditworthiness otherwise achieved by a business on a stand-alone basis, thereby facilitating the availability of sufficient credit to accomplish their intended business purposes. Most of the contingent obligations relate to future performance commitments which the Company or its businesses expect to fulfill within the normal course of business. The expiration dates of these guarantees vary from less than 1 year to no more than 33 years. The following table summarizes the Parent Company’s contingent contractual obligations as of March 31, 2024. Amounts presented in the following table represent the Parent Company’s current undiscounted exposure to guarantees and the range of maximum undiscounted potential exposure. The maximum exposure is not reduced by the amounts, if any, that could be recovered under the recourse or collateralization provisions in the guarantees. Contingent Contractual Obligations Maximum Exposure (in millions) Number of Agreements Maximum Exposure Range for Each Agreement (in millions) Guarantees and commitments $ 3,566 84 <$1 — 970 Letters of credit under bilateral agreements 234 4 $54 — 64 Letters of credit under the unsecured credit facilities 210 30 <$1 — 70 Letters of credit under the revolving credit facility 29 12 <$1 — 6 Surety bonds 2 2 <$1 — 1 Total $ 4,041 132 During the three months ended March 31, 2024, the Company paid letter of credit fees ranging from 1% to 3% per annum on the outstanding amounts of letters of credit. Subsidiary Guarantees and Letters of Credit — In connection with certain project financings (including tax equity transactions), acquisitions and dispositions, power purchases, EPC contracts, and other agreements, certain of the Company's subsidiaries have expressly undertaken limited obligations and commitments, most of which will only be effective or will be terminated upon the occurrence of future events, or are customary payment guarantees for amounts due under existing contracts in the normal course of business. These contingent contractual obligations are issued at the subsidiary level and are non-recourse to the Parent Company. As of March 31, 2024, the maximum undiscounted potential exposure to guarantees issued by our subsidiaries was $2.6 billion, including $1.6 billion of customary payment guarantees under EPC contracts and other agreements, and $995 million of tax equity financing related guarantees. In addition, as of March 31, 2024, our subsidiaries had $643 million of letters of credit outstanding. Contingencies Environmental — The Company periodically reviews its obligations as they relate to compliance with environmental laws, including site restoration and remediation. For the periods ended March 31, 2024 and December 31, 2023, the Company recognized liabilities of $8 million and $9 million for projected environmental remediation costs, respectively. Due to the uncertainties associated with environmental assessment and remediation activities, future costs of compliance or remediation could be higher or lower than the amount currently accrued. Moreover, where no liability has been recognized, it is reasonably possible that the Company may be required to incur remediation costs or make expenditures in amounts that could be material but could not be estimated as of March 31, 2024. In aggregate, the Company estimates the range of potential losses related to environmental matters, where estimable, to be immaterial. The amounts considered reasonably possible do not include amounts accrued as discussed above. Litigation — The Company is involved in certain claims, suits and legal proceedings in the normal course of business. The Company accrues for litigation and claims when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. The Company has recognized aggregate liabilities for all claims of approximately $16 million and $17 million as of March 31, 2024 and December 31, 2023, respectively. These amounts are reported on the Condensed Consolidated Balance Sheets within Accrued and other liabilities and Other noncurrent liabilities . A significant portion of these accrued liabilities relate to regulatory matters and commercial disputes in international jurisdictions. There can be no assurance that these accrued liabilities will be adequate to cover all existing and future claims or that we will have the liquidity to pay such claims as they arise. Where no accrued liability has been recognized, it is reasonably possible that some matters could be decided unfavorably to the Company and could require the Company to pay damages or make expenditures in amounts that could be material but could not be estimated as of March 31, 2024. The material contingencies where a loss is reasonably possible primarily include disputes with offtakers, suppliers and EPC contractors; alleged breaches of contract; alleged violation of laws and regulations; income tax and non-income tax matters with tax authorities; and regulatory matters. In aggregate, the Company estimates the range of potential losses, where estimable, related to these reasonably possible material contingencies to be between $55 million and $91 million. The amounts considered reasonably possible do not include the amounts accrued, as discussed above. These material contingencies do not include income tax-related contingencies which are considered part of our uncertain tax positions.

Lessor, Lease, Description [Line Items]
Lessor, Operating Leases	LEASES LESSOR — The Company has operating leases for certain generation contracts that contain provisions to provide capacity to a customer, which is a stand-ready obligation to deliver energy when required by the customer. Capacity obligations are generally considered lease elements as they cover the majority of available output from a facility. The allocation of contract payments between the lease and non-lease elements is made at the inception of the lease. Lease receipts from such contracts are recognized as lease revenue on a straight-line basis over the lease term, whereas variable lease receipts are recognized when earned. The following table presents lease revenue from operating leases in which the Company is the lessor, recognized in Revenue on the Condensed Consolidated Statements of Operations for the periods indicated (in millions): Three Months Ended March 31, Operating Lease Revenue 2024 2023 Total lease revenue $ 115 $ 121 Less: Variable lease revenue (13) (8) Total Non-variable lease revenue $ 102 $ 113 The following table presents the underlying gross assets and accumulated depreciation of operating leases included in Property, plant and equipment on the Condensed Consolidated Balance Sheets as of the periods indicated (in millions): Property, Plant and Equipment, Net March 31, 2024 December 31, 2023 Gross assets $ 1,178 $ 1,227 Less: Accumulated depreciation (190) (182) Net assets $ 988 $ 1,045 The option to extend or terminate a lease is based on customary early termination provisions in the contract, such as payment defaults, bankruptcy, and lack of performance on energy delivery. The Company has not recognized any early terminations as of March 31, 2024. Certain leases may provide for variable lease payments based on usage or index-based (e.g., the U.S. Consumer Price Index) adjustments to lease payments. The following table shows the future lease receipts as of March 31, 2024 for the remainder of 2024 through 2028 and thereafter (in millions): Future Cash Receipts for Sales-Type Leases Operating Leases 2024 $ 25 $ 292 2025 33 390 2026 33 279 2027 33 183 2028 33 60 Thereafter 461 490 Total $ 618 $ 1,694 Less: Imputed interest (307) Present value of total lease receipts $ 311 Battery Storage Lease Arrangements — The Company constructs and operates projects consisting only of a stand-alone BESS facility, as well as projects that pair a BESS with solar energy systems. These projects allow more flexibility on when to provide energy to the grid. The Company will enter into PPAs for the full output of the facility that allow customers the ability to determine when to charge and discharge the BESS. These arrangements include both lease and non-lease elements under ASC 842, with the BESS component typically constituting a sales-type lease. The Company recognized lease revenue on sales-type leases through interest income of $4 million for both the three months ended March 31, 2024 and March 31, 2023. The Company recorded a gain at commencement of sales-type leases of $5 million for the three months ended March 31, 2024. No gains were recorded for the three months ended March 31, 2023. This amount is recognized in Other income in the Condensed Consolidated Statement of Operations. See Note 15— Other Income and Expense for further information.

Redeemable Stock of Subsidiaries [Abstract]
Redeemable Noncontrolling Interest [Table Text Block]	REDEEMABLE STOCK OF SUBSIDIARIES Equity securities with redemption features that are not solely within the control of the issuer are classified as temporary equity and recorded in Redeemable stock of subsidiaries on the Condensed Consolidated Balance Sheets. Generally, these instruments are initially measured at fair value and are subsequently adjusted for income and dividends allocated to the noncontrolling interest. Subsequent measurement and classification may vary depending on whether the instrument is probable of becoming redeemable. For those securities that are currently redeemable or where it is probable that the instrument will become redeemable, any changes from the carrying value to redemption value are recognized in temporary equity against Additional paid-in capital . When the instrument is not probable of becoming redeemable, no adjustment to the carrying value is recognized.

Segments

Segment Reporting [Abstract]
SEGMENTS	SEGMENTS The segment reporting structure uses the Company’s management reporting structure as its foundation to reflect how the Company manages the businesses internally. The management reporting structure is composed of four SBUs, mainly organized by technology, led by our President and Chief Executive Officer. Using the accounting guidance on segment reporting, the Company determined that its four operating segments are aligned with its four reportable segments corresponding to its SBUs. • Renewables — Solar, wind, energy storage, and hydro generation facilities; • Utilities — AES Indiana, AES Ohio, and AES El Salvador regulated utilities and their generation facilities; • Energy Infrastructure — Natural gas, LNG, coal, pet coke, diesel, and oil generation facilities, and our businesses in Chile, which have a mix of generation sources, including renewables, that are pooled to service our existing PPAs; and • New Energy Technologies — Green hydrogen initiatives and investments in Fluence, Uplight, 5B, and other new and innovative energy technology businesses. Our Renewables, Utilities and Energy Infrastructure SBUs participate in our generation business line, in which we own and/or operate power plants to generate and sell power to customers, such as utilities, industrial users, and other intermediaries. Our Utilities SBU participates in our utilities business line, in which we own and/or operate utilities to generate or purchase, distribute, transmit, and sell electricity to end-user customers in the residential, commercial, industrial, and governmental sectors within a defined service area. In certain circumstances, our utilities also generate and sell electricity on the wholesale market. Our New Energy Technologies SBU includes investments in new and innovative technologies to support leading-edge greener energy solutions. Included in “Corporate and Other” are the results of the AES self-insurance company, corporate overhead costs which are not directly associated with the operations of our four reportable segments, and certain intercompany charges such as self-insurance premiums which are fully eliminated in consolidation. The Company uses Adjusted EBITDA as its primary segment performance measure. Adjusted EBITDA, a non-GAAP measure, is defined by the Company as earnings before interest income and expense, taxes, depreciation and amortization, adjusted for the impact of NCI and interest, taxes, depreciation and amortization of our equity affiliates, and adding back interest income recognized under service concession arrangements; excluding gains or losses of both consolidated entities and entities accounted for under the equity method due to (a) unrealized gains or losses pertaining to derivative transactions, equity securities, and financial assets and liabilities measured using the fair value option; (b) unrealized foreign currency gains or losses; (c) gains, losses, benefits, and costs associated with dispositions and acquisitions of business interests, including early plant closures, and gains and losses recognized at commencement of sales-type leases; (d) losses due to impairments; and (e) gains, losses, and costs due to the early retirement of debt or troubled debt restructuring. The Company has concluded Adjusted EBITDA better reflects the underlying business performance of the Company and is the most relevant measure considered in the Company's internal evaluation of the financial performance of its segments. Additionally, given its large number of businesses and overall complexity, the Company concluded that Adjusted EBITDA is a more transparent measure that better assists investors in determining which businesses have the greatest impact on the Company's results. Revenue and Adjusted EBITDA are presented before inter-segment eliminations, which includes the effect of intercompany transactions with other segments except for charges for certain management fees and the write-off of intercompany balances, as applicable. All intra-segment activity has been eliminated within the segment. Inter-segment activity has been eliminated within the total consolidated results.

Contract Balances — The timing of revenue recognition, billings, and cash collections results in accounts receivable and contract liabilities. The contract liabilities from contracts with customers were $335 million and $328 million as of March 31, 2024 and December 31, 2023, respectively. During the three months ended March 31, 2024 and 2023, we recognized revenue of $46 million and $7 million, respectively, that was included in the corresponding contract liability balance at the beginning of the periods. In June 2023, the Company closed on an agreement to terminate the PPA for the Warrior Run coal-fired power plant for total consideration of $357 million, to be paid by the offtaker through the end of the previous contract term in January 2030. Under the termination agreement, the plant will continue providing capacity through May 2024. The termination represents a contract modification under which the discounted termination payments, as well as a pre-existing contract liability, will be recognized as revenue on a straight-line basis over the remaining performance obligation period for approximately $32 million per month. On February 1, 2024, the Company executed a receivable sale agreement to transfer all of its rights, title, and interest in the remaining future cash flows under this agreement. At the time of execution, the transaction was considered a sale of future revenue under U.S. GAAP, and as such, the net proceeds of $273 million were recorded as debt . As of March 31, 2024, $267 million remains outstanding and is recorded in the current portion of Non-recourse debt on the Condensed Consolidated Balance Sheets. As of March 31, 2024, the corresponding receivables met the held-for-sale criteria and the receivable balance of $214 million, net of valuation allowance of $6 million, was classified as Current held-for-sale assets on the Condensed Consolidated Balance Sheets. See Note 18— Held-For-Sale and Dispositions for further information. A significant financing arrangement exists for our Mong Duong plant in Vietnam. The plant was constructed under a build, operate, and transfer contract and will be transferred to the Vietnamese government after the completion of a 25-year PPA. The performance obligation to construct the facility was substantially completed in 2015. Contract consideration related to the construction, but not yet collected through the 25-year PPA, was reflected on the Condensed Consolidated Balance Sheet. As of March 31, 2024 and December 31, 2023, Mong Duong met the held-for-sale criteria and the loan receivable balance of $1 billion and $1.1 billion, net of CECL reserves of $25 million and $26 million, respectively, was classified as held-for-sale assets. Of the loan receivable balance, $111 million and $108 million, respectively, was classified as Current held-for-sale assets , and $934 million and $962 million, respectively, was classified as Noncurrent held-for-sale assets on the Condensed Consolidated Balance Sheets.

See Note 18— Held-for-Sale and Dispositions for further information. Mong Duong is reported in the Energy Infrastructure SBU reportable segment. Jordan — In November 2020, the Company signed an agreement to sell approximately 26% ownership interest in Amman East and IPP4 for $58 million. The generation plants were classified as held-for-sale until the sale was completed in March 2024. Due to the delay in closing the transaction, the carrying amount of the asset group in subsequent periods exceeded the agreed-upon sales price, and total pre-tax impairment expense of $14 million was recorded during the three months ended March 31, 2023. See Note 18 —Held-for-Sale and Dispositions for further information. Amman East and IPP4 are reported in the Energy Infrastructure SBU reportable segment.

The proceeds were used primarily to repay existing indebtedness and for general corporate purposes. Under the requirements of the PPA termination agreement, Warrior Run must satisfy performance obligations which continue through May 31, 2024. As a result, Warrior Run reclassified the related financing receivable as held-for-sale given its intent and ability to sell the receivable once the performance period has concluded. As of March 31, 2024, the carrying value of the receivable classified as held-for-sale was $214 million, including a valuation allowance of $6 million. Warrior Run is reported in the Energy Infrastructure SBU reportable segment. Mong Duong — In November 2023, the Company entered into an agreement to sell its entire 51% ownership interest in Mong Duong 2, a coal-fired plant in Vietnam, and 51% equity interest in Mong Duong Finance Holdings B.V., an SPV accounted for as an equity affiliate (collectively "Mong Duong"). The sale is subject to regulatory approval and is expected to close in mid-2025. As a result, Mong Duong was classified as held-for-sale, but did not meet the criteria to be reported as discontinued operations. On a consolidated basis, the carrying value of net assets after impairment of the plant held-for-sale as of March 31, 2024 was $410 million. Mong Duong is reported in the Energy Infrastructure SBU reportable segment.

Dispositions Jordan — In March 2024, the Company completed the sale of approximately 26% ownership interest in the Amman East and IPP4 generation plants for a sale price of $58 million. After adjusting for dividends received since the execution of the sale and purchase agreement, the Company received a net cash payment of $45 million. The transaction resulted in a pre-tax loss on sale of $10 million, reported in Gain on disposal and sale of business interests on the Condensed Consolidated Statement of Operations. After completion of the sale, the Company retained 10% ownership interest in each of the businesses, resulting in deconsolidation and recognition as equity method investments. Amman East and IPP4 are reported in the Energy Infrastructure SBU reportable segment.

Business Combinations [Abstract]
Acquisitions	. ACQUISITIONS Hoosier Wind — In August 2023, the Company, through its subsidiary AES Indiana, filed for IURC issuance of a Certificate of Public Convenience and Necessity (“CPCN”) approving the acquisition of 100% of the interests in Hoosier Wind Project, LLC., which is an existing 106 MW wind facility located in Benton County, Indiana. IURC approval was received on January 24, 2024, and the transaction closed on February 29, 2024. The transaction was accounted for as an asset acquisition that did not meet the definition of a business. Of the total consideration transferred of $93 million, including transaction costs, approximately $49 million was allocated to the identifiable assets acquired on a relative fair value basis, primarily consisting of tangible wind farm assets and typical working capital items. The remaining consideration was allocated to the termination of the pre-existing PPA between AES Indiana and the Hoosier Wind Project, estimated using a discounted cash flow valuation methodology, which was deferred as a long-term regulatory asset. Hoosier Wind is reported in the Utilities SBU reportable segment.

Earnings Per Share [Abstract]
EARNINGS PER SHARE	EARNINGS PER SHARE Basic and diluted earnings per share are based on the weighted average number of shares of common stock and potential common stock outstanding during the period. Potential common stock, for purposes of determining diluted earnings per share, includes the effects of dilutive RSUs, stock options, and equity units. The effect of such potential common stock is computed using the treasury stock method for RSUs and stock options, and is computed using the if-converted method for equity units. The following table is a reconciliation of the numerator and denominator of the basic and diluted earnings per share computation for income from continuing operations for the three months ended March 31, 2024 and 2023, where income represents the numerator and weighted average shares represent the denominator. Three Months Ended March 31, 2024 2023 (in millions, except per share data) Income Shares $ per Share Income Shares $ per Share BASIC EARNINGS PER SHARE Income from continuing operations attributable to The AES Corporation common stockholders $ 432 690 $ 0.63 $ 151 669 $ 0.22 Less: Increase in redemption value of redeemable stock of subsidiaries (6) (0.01) $ — — Income available to The AES Corporation common stockholders $ 426 690 $ 0.62 $ 151 669 $ 0.22 EFFECT OF DILUTIVE SECURITIES Stock options — — — — 1 — Restricted stock units — 2 — — 2 — Equity units — 20 (0.02) — 40 (0.01) DILUTED EARNINGS PER SHARE $ 426 712 $ 0.60 $ 151 712 $ 0.21 For the three months ended March 31, 2024, income from continuing operations available to AES common stockholders included a $6 million adjustment related to the increase of the carrying value of redeemable stock of subsidiaries at AES Clean Energy Development, as a result of a non-fair value redemption feature. The Company has elected to administer the entire non-fair value redemption adjustment consistent with the treatment of dividends in the earnings per share calculation. While the adjustment reduced net income available to AES common stockholders and earnings per share, it did not impact Net income in the Condensed Consolidated Statement of Operations. The calculation of diluted earnings per share excluded 2 million and 1 million outstanding stock awards for the three months ended March 31, 2024 and March 31, 2023, which would be anti-dilutive. These stock awards could potentially dilute basic earnings per share in the future. As described in Note 12 —Equity

Unusual Risks and Uncertainties [Table Text Block]	RISKS AND UNCERTAINTIES Puerto Rico — In 2023, AES Puerto Rico took certain measures to address identified liquidity challenges. On July 6, 2023, PREPA agreed to the release of funds in the escrow account guaranteeing AES Puerto Rico’s obligations under the Power Purchase and Operating Agreement (“PPOA”) in order to provide additional liquidity for the business. During the fourth quarter of 2023, a restructuring support agreement was executed by AES Puerto Rico and its noteholders and a PPOA amendment was approved by PREPA. The restructuring closed on March 5, 2024. See Note 8— Debt included in Item 1.— Financial Statements of this Form 10-Q for further information. Considering the information available as of the filing date, management believes the carrying amount of our long-lived assets at AES Puerto Rico of $78 million is recoverable as of March 31, 2024.

Consolidation	Consolidation — In this Quarterly Report, the terms “AES,” “the Company,” “us” or “we” refer to the consolidated entity, including its subsidiaries and affiliates. The terms “The AES Corporation” or “the Parent Company” refer only to the publicly held holding company, The AES Corporation, excluding its subsidiaries and affiliates. Furthermore, VIEs in which the Company has a variable interest have been consolidated where the Company is the primary beneficiary. Investments in which the Company has the ability to exercise significant influence, but not control, are accounted for using the equity method of accounting, except for our investment in Alto Maipo, for which we have elected the fair value option as permitted under ASC 825. All intercompany transactions and balances have been eliminated in consolidation.
Basis of Presentation and Significant Accounting Policies [Text Block]	Interim Financial Presentation — The accompanying unaudited condensed consolidated financial statements and footnotes have been prepared in accordance with GAAP, as contained in the FASB ASC, for interim financial information and Article 10 of Regulation S-X issued by the SEC. Accordingly, they do not include all the information and footnotes required by GAAP for annual fiscal reporting periods. In the opinion of management, the interim financial information includes all adjustments of a normal recurring nature necessary for a fair presentation of the results of operations, financial position, comprehensive income, changes in equity, and cash flows. The results of operations for the three months ended March 31, 2024 are not necessarily indicative of expected results for the year ending December 31, 2024. The accompanying condensed consolidated financial statements are unaudited and should be read in conjunction with the 2023 audited consolidated financial statements and notes thereto, which are included in the 2023 Form 10-K filed with the SEC on February 29, 2024 (the “2023 Form 10-K”).

Segments Segments (Policies)

Segments Segments (Policies)	3 Months Ended

Segment Reporting [Abstract]
Segment Reporting	SEGMENTS The segment reporting structure uses the Company’s management reporting structure as its foundation to reflect how the Company manages the businesses internally. The management reporting structure is composed of four SBUs, mainly organized by technology, led by our President and Chief Executive Officer. Using the accounting guidance on segment reporting, the Company determined that its four operating segments are aligned with its four reportable segments corresponding to its SBUs. • Renewables — Solar, wind, energy storage, and hydro generation facilities; • Utilities — AES Indiana, AES Ohio, and AES El Salvador regulated utilities and their generation facilities; • Energy Infrastructure — Natural gas, LNG, coal, pet coke, diesel, and oil generation facilities, and our businesses in Chile, which have a mix of generation sources, including renewables, that are pooled to service our existing PPAs; and • New Energy Technologies — Green hydrogen initiatives and investments in Fluence, Uplight, 5B, and other new and innovative energy technology businesses. Our Renewables, Utilities and Energy Infrastructure SBUs participate in our generation business line, in which we own and/or operate power plants to generate and sell power to customers, such as utilities, industrial users, and other intermediaries. Our Utilities SBU participates in our utilities business line, in which we own and/or operate utilities to generate or purchase, distribute, transmit, and sell electricity to end-user customers in the residential, commercial, industrial, and governmental sectors within a defined service area. In certain circumstances, our utilities also generate and sell electricity on the wholesale market. Our New Energy Technologies SBU includes investments in new and innovative technologies to support leading-edge greener energy solutions. Included in “Corporate and Other” are the results of the AES self-insurance company, corporate overhead costs which are not directly associated with the operations of our four reportable segments, and certain intercompany charges such as self-insurance premiums which are fully eliminated in consolidation. The Company uses Adjusted EBITDA as its primary segment performance measure. Adjusted EBITDA, a non-GAAP measure, is defined by the Company as earnings before interest income and expense, taxes, depreciation and amortization, adjusted for the impact of NCI and interest, taxes, depreciation and amortization of our equity affiliates, and adding back interest income recognized under service concession arrangements; excluding gains or losses of both consolidated entities and entities accounted for under the equity method due to (a) unrealized gains or losses pertaining to derivative transactions, equity securities, and financial assets and liabilities measured using the fair value option; (b) unrealized foreign currency gains or losses; (c) gains, losses, benefits, and costs associated with dispositions and acquisitions of business interests, including early plant closures, and gains and losses recognized at commencement of sales-type leases; (d) losses due to impairments; and (e) gains, losses, and costs due to the early retirement of debt or troubled debt restructuring. The Company has concluded Adjusted EBITDA better reflects the underlying business performance of the Company and is the most relevant measure considered in the Company's internal evaluation of the financial performance of its segments. Additionally, given its large number of businesses and overall complexity, the Company concluded that Adjusted EBITDA is a more transparent measure that better assists investors in determining which businesses have the greatest impact on the Company's results. Revenue and Adjusted EBITDA are presented before inter-segment eliminations, which includes the effect of intercompany transactions with other segments except for charges for certain management fees and the write-off of intercompany balances, as applicable. All intra-segment activity has been eliminated within the segment. Inter-segment activity has been eliminated within the total consolidated results.
