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 2022 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: September 30, 2023 December 31, 2022 Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Assets DEBT SECURITIES: Available-for-sale: Certificates of deposit $ — $ 493 $ — $ 493 $ — $ 698 $ — $ 698 Government debt securities — — — — — 3 — 3 Total debt securities — 493 — 493 — 701 — 701 EQUITY SECURITIES: Mutual funds 43 — — 43 38 — — 38 Total equity securities 43 7 — 50 38 — — 38 DERIVATIVES: Interest rate derivatives — 478 — 478 — 314 — 314 Foreign currency derivatives — 22 46 68 — 22 64 86 Commodity derivatives — 137 4 141 — 232 13 245 Total derivatives — assets — 637 50 687 — 568 77 645 TOTAL ASSETS $ 43 $ 1,137 $ 50 $ 1,230 $ 38 $ 1,269 $ 77 $ 1,384 Liabilities Contingent consideration $ — $ — $ 267 $ 267 $ — $ — $ 48 $ 48 DERIVATIVES: Interest rate derivatives — — — — — 6 — 6 Cross-currency derivatives — 54 — 54 — 42 — 42 Foreign currency derivatives — 26 — 26 — 20 — 20 Commodity derivatives — 127 80 207 — 346 60 406 Total derivatives — liabilities — 207 80 287 — 414 60 474 TOTAL LIABILITIES $ — $ 207 $ 347 $ 554 $ — $ 414 $ 108 $ 522 As of September 30, 2023, 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 and nine months ended September 30, 2023. The level 3 contingent consideration relates mainly to the acquisition of Bellefield on June 5, 2023. For further information on the acquisition, see Note 18— Acquisitions. 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. The following table presents gross proceeds from the sale of available-for-sale securities during the periods indicated (in millions): Three Months Ended September 30, Nine Months Ended September 30, 2023 2022 2023 2022 Gross proceeds from sale of available-for-sale securities $ 308 $ 318 $ 1,047 $ 665 The following tables present a reconciliation of assets and liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the three and nine months ended September 30, 2023 and 2022 (presented net by type of derivative in millions). Transfers between Level 3 and Level 2 principally result from changes in the significance of unobservable inputs used to calculate the credit valuation adjustment.

For foreign currency derivatives, increases (decreases) in the estimate of the above exchange rate would increase (decrease) the value of the derivative. Contingent consideration is primarily related to future milestone payments associated with acquisitions of renewable 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 Nine Months Ended September 30, 2023 Level 1 Level 2 Level 3 Long-lived asset groups held and used: Norgener (2) 5/1/2023 $ 196 $ — $ — $ 24 $ 137 GAF Projects (AES Renewable Holdings) 5/31/2023 29 — — 11 18 TEP 7/31/2023 153 — — 94 59 TEG 7/31/2023 170 — — 93 77 Held-for-sale businesses: (3) Jordan (4) 3/31/2023 $ 179 $ — $ 170 $ — $ 14 Jordan (4) 6/30/2023 179 — 170 — 15 Jordan (4) 9/30/2023 178 — 170 — 14 Measurement Date Carrying Amount (1) Fair Value Nine Months Ended September 30, 2022 Level 1 Level 2 Level 3 Pre-tax Loss Long-lived asset groups held and used: Maritza 4/30/2022 $ 920 $ — $ — $ 452 $ 468 Held-for-sale businesses: (3) Jordan (4) 9/30/2022 216 — 170 — 51 _____________________________ (1) Represents the carrying values of the asset groups at the dates of measurement, before fair value adjustment. (2) The Norgener asset group includes long-lived assets, inventory, land, and other working capital, however per ASC 360-10, the pre-tax impairment expense is limited to the carrying amount of the long-lived assets. See Note 15— Asset Impairment Expense for further information. The Company evaluated the carrying amount of the assets outside the scope of ASC 360-10 and determined that the carrying value of the other assets should not be reduced. (3) See Note 17— Held-for-Sale for further information. (4) The pre-tax loss recognized was calculated using the $170 million fair value of the Jordan disposal group less costs to sell of $5 million for the September 30, 2022 and March 31, 2023 measurement dates and $6 million for the June 30, 2023 and September 30, 2023 measurement dates. The following table summarizes the significant unobservable inputs used in the Level 3 measurement of long-lived assets held and used measured on a nonrecurring basis during the nine months ended September 30, 2023 (in millions, except range amounts): Fair Value Valuation Technique Unobservable Input Range (Weighted Average) Long-lived asset groups held and used: TEP $ 94 Discounted cash flow Annual revenue growth (31)% to 6% (-2%) Annual variable margin 22% to 37% (26%) Discount rate 14% to 25% (14%) TEG 93 Discounted cash flow Annual revenue growth (7)% to 9% (—%) Annual variable margin 14% to 33% (20%) Discount rate 14% to 25% (14%) Norgener (1) 24 Discounted cash flow Annual revenue growth (90)% to 994% (85%) Annual variable margin (75)% to 276% (16%) GAF Projects (AES Renewable Holdings) 11 Discounted cash flow Annual revenue growth (42)% to 44% (1%) Annual variable margin (194)% to 77% (66%) Discount rate 9% Total $ 222 _____________________________ (1) The fair value of the Norgener asset group is mainly related to existing coal inventory not subject to impairment under ASC 360-10.

For foreign currency derivatives, increases (decreases) in the estimate of the above exchange rate would increase (decrease) the value of the derivative. Contingent consideration is primarily related to future milestone payments associated with acquisitions of renewable 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).

(2) The Norgener asset group includes long-lived assets, inventory, land, and other working capital, however per ASC 360-10, the pre-tax impairment expense is limited to the carrying amount of the long-lived assets. See Note 15— Asset Impairment Expense for further information. The Company evaluated the carrying amount of the assets outside the scope of ASC 360-10 and determined that the carrying value of the other assets should not be reduced. (3) See Note 17— Held-for-Sale for further information. (4) The pre-tax loss recognized was calculated using the $170 million fair value of the Jordan disposal group less costs to sell of $5 million for the September 30, 2022 and March 31, 2023 measurement dates and $6 million for the June 30, 2023 and September 30, 2023 measurement dates. The following table summarizes the significant unobservable inputs used in the Level 3 measurement of long-lived assets held and used measured on a nonrecurring basis during the nine months ended September 30, 2023 (in millions, except range amounts): Fair Value Valuation Technique Unobservable Input Range (Weighted Average) Long-lived asset groups held and used: TEP $ 94 Discounted cash flow Annual revenue growth (31)% to 6% (-2%) Annual variable margin 22% to 37% (26%) Discount rate 14% to 25% (14%) TEG 93 Discounted cash flow Annual revenue growth (7)% to 9% (—%) Annual variable margin 14% to 33% (20%) Discount rate 14% to 25% (14%) Norgener (1) 24 Discounted cash flow Annual revenue growth (90)% to 994% (85%) Annual variable margin (75)% to 276% (16%) GAF Projects (AES Renewable Holdings) 11 Discounted cash flow Annual revenue growth (42)% to 44% (1%) Annual variable margin (194)% to 77% (66%) Discount rate 9% Total $ 222 _____________________________ (1) The fair value of the Norgener asset group is mainly related to existing coal inventory not subject to impairment under ASC 360-10.

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): September 30, 2023 December 31, 2022 Gross Receivable Allowance Net Receivable Gross Receivable Allowance Net Receivable U.S. $ 77 $ — $ 77 $ 46 $ — $ 46 Chile 29 — 29 239 — 239 Other 12 — 12 18 — 18 Total $ 118 $ — $ 118 $ 303 $ — $ 303 U.S. — During this period, AES has recorded non-current receivables pertaining to the sale of the Redondo Beach land and the Warrior Run PPA termination agreement. The anticipated collection period extends beyond September 30, 2024. See Note 13— Revenue 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 renewable contracts are incorporated to supply regulated contracts. Consequently, costs incurred in excess of the July 1, 2019 price are accumulated and borne by generators. Through different programs, AES Andes aims to reduce its exposure and has already sold a significant portion of the receivables accumulated as of September 30, 2023. On August 14, 2023, AES Andes executed an agreement aiming for the sale of up to $227 million of receivables pursuant to the Stabilization Funds, of which $122 million was sold and collected as of September 30, 2023. Through different agreements and programs, as of September 30, 2023, $16 million of current receivables and $7 million of noncurrent receivables were recorded in Accounts receivable and Other noncurrent assets , respectively. Additionally, $22 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 September 30, 2023.

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 and majority-owned unconsolidated subsidiaries that are accounted for using the equity method (in millions): 50%-or-less Owned Affiliates Majority-Owned Unconsolidated Subsidiaries Nine Months Ended September 30, 2023 2022 2023 2022 Revenue $ 2,089 $ 1,218 $ 1 $ 1 Operating loss (21) (322) (1) — Net loss (129) (410) (1) — Net loss attributable to affiliates (111) (332) (1) — Grupo Energía Gas Panamá — In September 2023, AES Latin America completed the sale of its interest in Grupo Energía Gas Panamá, a joint venture formed for the Gatun combined cycle natural gas development project, to AES Panama, a 49%-owned consolidated subsidiary. As a result of the transaction, the Company’s effective ownership in Grupo Energía Gas Panamá decreased from 49% to approximately 24%. As the Company still does not control the investment after this transaction, it continues to be accounted for as an equity method investment and is reported in the Energy Infrastructure 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 (loss) 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 September 30, 2023, the fair value is insignificant. Alto Maipo is reported in the Energy Infrastructure SBU reportable segment.

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 are unsecured and are fully guaranteed by the Parent Company. 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. As of September 30, 2023, the Company had $604 million outstanding borrowings under the commercial paper program with a weighted average interest rate of 6.16%. The Notes are classified as noncurrent. Revolving Credit Facility — In September 2022, AES executed an amendment to its revolving credit facility. The aggregate commitment under the new agreement is $1.5 billion and matures in August 2027. The existing credit agreement had an aggregate commitment of $1.25 billion and matured in September 2026. As of September 30, 2023, AES had no outstanding drawings under its revolving credit facility.

In January 2023, AES Hispanola Holdings BV 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 partially repay the $500 million bridge loan executed in 2022. The remaining principal outstanding of the bridge loan was repaid with proceeds from operating cash flows as well as cash from the Parent Company. As a result of these transactions, the Company recognized a loss on extinguishment of debt of $1 million for the nine months ended September 30, 2023. United Kingdom — On January 6, 2022, Mercury Chile HoldCo LLC (“Mercury Chile”), a UK based company, executed a $350 million bridge loan, and used the proceeds, as well as an additional capital contribution of $196 million from the Parent Company, to purchase the minority interest in AES Andes through intermediate holding companies (see Note 11— Equity for further information). On January 24, 2022, Mercury Chile issued $360 million aggregate principal of 6.5% senior secured notes due in 2027 and used the proceeds from the issuance to fully prepay the $350 million bridge loan. 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 $893 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 a result of the 2023 issuance, AES Clean Energy Development recorded an increase in liabilities of $215 million, resulting in an aggregate carrying amount of the notes attributable to AES Clean Energy Development and AES Renewable Holdings of $252 million as of September 30, 2023. 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 $2.3 billion, bringing the total commitments under the new agreements to $3.5 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 $1.4 billion in 2023, resulting in total commitments used under the revolving credit facilities, as of September 30, 2023, of $2.7 billion. As of September 30, 2023, 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 September 30, 2023 and December 31, 2022, approximately $369 million and $424 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 September 30, 2023 and December 31, 2022, approximately $91 million and $56 million, respectively, 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 $1.4 billion at September 30, 2023. The following table summarizes the Company’s subsidiary non-recourse debt in default (in millions) as of September 30, 2023. 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 (Liabilities) AES Mexico Generation Holdings (TEG and TEP) (1) Covenant $ 157 $ 50 AES Puerto Rico Covenant/Payment 143 (169) AES Ilumina (Puerto Rico) Covenant 25 28 AES Jordan Solar Covenant 7 11 Total $ 332 _____________________________ (1) On October 3, 2023, AES Mexico Generation Holdings failed to comply with a covenant on its debt, resulting in a technical default. The associated non-recourse debt is classified as current in the accompanying Condensed Consolidated Balance Sheets. The amounts in default related to AES Puerto Rico are covenant and payment defaults. In July 2023, AES Puerto Rico signed forbearance and standstill agreements with its noteholders because of the insufficiency of funds to meet the principal and interest obligations on its Series A Bond Loans due and payable on June 1, 2023, and going forward. AES Puerto Rico continues to work with PREPA and its noteholders on these liquidity challenges. These agreements will expire on December 31, 2023. All other defaults listed are not payment defaults. All other subsidiary non-recourse defaults were 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 or group of subsidiaries for which the non-recourse debt is in default provides 20% or more of the Parent Company’s total cash distributions from businesses for the four most recently completed fiscal quarters. As of September 30, 2023, the Company had no defaults which resulted in, or were at risk of triggering, 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 Guarantees, Letters of Credit and Commitments — In connection with certain project financings, acquisitions and dispositions, power purchases 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 one year to no more than 33 years. The following table summarizes the Parent Company’s contingent contractual obligations as of September 30, 2023. Amounts presented in the following table represent the Parent Company’s current undiscounted exposure to guarantees and the range of maximum undiscounted potential exposure and excludes guarantees presented on the Condensed Consolidated Balance Sheets within Recourse debt . 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 Amount (in millions) Number of Agreements Maximum Exposure Range for Each Agreement (in millions) Guarantees and commitments $ 2,431 81 <$1 — 484 Letters of credit under bilateral agreements 248 3 $59 — 125 Letters of credit under the unsecured credit facilities 136 30 <$1 — 50 Letters of credit under the revolving credit facility 39 6 <$1 — 30 Surety bonds 2 2 <$1 — 1 Total $ 2,856 122 During the nine months ended September 30, 2023, the Company paid letter of credit fees ranging from 1% to 3% per annum on the outstanding amounts of letters of credit. 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 September 30, 2023 and December 31, 2022, the Company recognized liabilities of $10 million for projected environmental remediation costs. 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 September 30, 2023. In aggregate, the Company estimates the range of potential losses related to environmental matters, where estimable, to be up to $12 million. 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 $22 million as of September 30, 2023 and December 31, 2022. 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 September 30, 2023. 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 $182 million and $219 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 receipts 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.

Equity [Abstract]
EQUITY	EQUITY Equity Units In March 2021, the Company issued 10,430,500 Equity Units with a total notional value of $1,043 million. Each Equity Unit has a stated amount of $100 and was initially issued as a Corporate Unit, consisting of a forward stock purchase contract (“2024 Purchase Contracts”) and a 10% undivided beneficial ownership interest in one share of 0% Series A Cumulative Perpetual Convertible Preferred Stock, issued without par and with a liquidation preference of $1,000 per share (“Series A Preferred Stock”). The Company concluded that the Equity Units should be accounted for as one unit of account based on the economic linkage between the 2024 Purchase Contracts and the Series A Preferred Stock, as well as the Company's assessment of the applicable accounting guidance relating to combining freestanding instruments. The Equity Units represent mandatorily convertible preferred stock. Accordingly, the shares associated with the combined instrument are reflected in diluted earnings per share using the if-converted method. In conjunction with the issuance of the Equity Units, the Company received approximately $1 billion in proceeds, net of underwriting costs and commissions, before offering expenses. The proceeds for the issuance of 1,043,050 shares are attributed to the Series A Preferred Stock for $838 million and $205 million for the present value of the quarterly payments due to holders of the 2024 Purchase Contracts ("Contract Adjustment Payments"). The proceeds were used for the development of the AES renewable businesses, U.S. utility businesses, LNG infrastructure, and for other developments determined by management. The Series A Preferred Stock will initially not bear any dividends and the liquidation preference of the convertible preferred stock will not accrete. The Series A Preferred Stock has no maturity date and will remain outstanding unless converted by holders or redeemed by the Company. Holders of the shares of the convertible preferred stock will have limited voting rights. The Series A Preferred Stock is pledged as collateral to support holders’ purchase obligations under the 2024 Purchase Contracts and can be remarketed. In connection with any successful remarketing, the Company may increase the dividend rate, increase the conversion rate, and modify the earliest redemption date for the convertible preferred stock. After any successful remarketing in connection with which the dividend rate on the convertible preferred stock is increased, the Company will pay cumulative dividends on the convertible preferred stock, if declared by the board of directors, quarterly in arrears from the applicable remarketing settlement date. Holders of Corporate Units may create Treasury Units or Cash Settled Units from their Corporate Units as provided in the Purchase Contract Agreement by substituting Treasury securities or cash, respectively, for the Convertible Preferred Stock comprising a part of the Corporate Units. The Company may not redeem the Series A Preferred Stock prior to March 22, 2024. At the election of the Company, on or after March 22, 2024, the Company may redeem for cash, all or any portion of the outstanding shares of the Series A Preferred Stock at a redemption price equal to 100% of the liquidation preference, plus any accumulated and unpaid dividends. The 2024 Purchase Contracts obligate the holders to purchase, on February 15, 2024, for a price of $100 in cash, a maximum number of 57,407,386 shares of the Company’s common stock (subject to customary anti-dilution adjustments). The 2024 Purchase Contract holders may elect to settle their obligation early, in cash. The Series A Preferred Stock is pledged as collateral to guarantee the holders’ obligations to purchase common stock under the terms of the 2024 Purchase Contracts. The initial settlement rate determining the number of shares that each holder must purchase will not exceed the maximum settlement rate and is determined over a market value averaging period preceding February 15, 2024. The initial maximum settlement rate of 3.864 was calculated using an initial reference price of $25.88, equal to the last reported sale price of the Company’s common stock on March 4, 2021. As of September 30, 2023, due to the customary anti-dilution provisions, the maximum settlement rate was 3.8768, equivalent to a reference price of $25.79. If the applicable market value of the Company’s common stock is less than or equal to the reference price, the settlement rate will be the maximum settlement rate; and if the applicable market value of common stock is greater than the reference price, the settlement rate will be a number of shares of the Company’s common stock equal to $100 divided by the applicable market value. Upon successful remarketing of the Series A Preferred Stock (“Remarketed Series A Preferred Stock”), the Company expects to receive additional cash proceeds of $1 billion and issue shares of Remarketed Series A Preferred Stock. The Company pays Contract Adjustment Payments to the holders of the 2024 Purchase Contracts at a rate of 6.875% per annum, payable quarterly in arrears on February 15, May 15, August 15, and November 15, commencing on May 15, 2021. The $205 million present value of the Contract Adjustment Payments at inception reduced the Series A Preferred Stock. As each quarterly Contract Adjustment Payment is made, the related liability is reduced and the difference between the cash payment and the present value will accrete to interest expense, approximately $5 million over the three-year term. As of September 30, 2023, the present value of the Contract Adjustment Payments was $36 million. The holders can settle the purchase contracts early, for cash, subject to certain exceptions and conditions in the prospectus supplement. Upon early settlement of any purchase contracts, the Company will deliver the number of shares of its common stock equal to 85% of the number of shares of common stock that would have otherwise been deliverable. Equity Transactions with Noncontrolling Interests AES Clean Energy Tax Equity Partnerships — The majority of solar projects under AES Clean Energy have been financed with tax equity structures, in which tax equity investors receive a portion of the economic attributes of the facilities, including tax attributes, that vary over the life of the projects. During the nine months ended September 30, 2023 and 2022, AES Clean Energy Development and AES Renewable Holdings, through multiple transactions, sold noncontrolling interests in project companies to tax equity partners, resulting in increases to NCI of $292 million and $210 million, respectively. In the third quarter of 2023, AES Renewable Holdings completed buyouts of tax equity partners at Buffalo Gap I, Buffalo Gap II and six other project companies, resulting in a decrease to NCI of $45 million and an increase to additional paid-in capital of $34 million. AES Clean Energy Development and AES Renewable Holdings are reported in the Renewables SBU reportable segment. Chile Renovables — Under its renewable partnership agreement with Global Infrastructure Management, LLC (“GIP”), AES Andes will contribute a specified pipeline of renewable development projects to Chile Renovables as the projects reach commercial operations, and GIP may make additional contributions to maintain its 49% ownership interest. During the nine months ended September 30, 2022 and 2023, AES Andes completed the sale of the following projects to Chile Renovables (in millions): Business Transaction Period Sale Price Increase to Noncontrolling Interests Increase (Decrease) to Additional Paid-In Capital Andes Solar 2a January 2022 $ 37 $ 28 $ 9 Los Olmos June 2022 80 68 12 Campo Lindo September 2023 50 59 (9) As the Company maintained control after these transactions, Chile Renovables continues to be consolidated by the Company within the Energy Infrastructure SBU reportable segment. AES Panama — In September 2023, AES Latin America completed the sale of its interest in the Grupo Energía Gas Panamá joint venture to AES Panama, a 49%-owned consolidated subsidiary. See Note 6— Investments in and Advances to Affiliates for further information. As a result of the transaction, AES Panama received $42 million from noncontrolling interest holders and the Company reclassified accumulated other comprehensive income from AOCL to NCI of $23 million. AES Panama is reported in the Renewables SBU reportable segment however the investment in Grupo Energía Gas Panamá is reported in the Energy Infrastructure SBU reportable segment. AES Brasil — In September 2022, AES Brasil commenced a private placement offering for its existing shareholders to subscribe for up to 107 million newly issued shares. AES Holdings Brasil Ltda. subscribed for 54 million shares and noncontrolling interest holders subscribed for 53 million shares, thereby increasing AES’ indirect beneficial interest in AES Brasil to 47.4%. AES Brasil received $77 million from noncontrolling interest holders during the third quarter of 2022, prior to the issuance of the shares in October 2022. Since the consideration received was nonrefundable, the impact was recorded in noncontrolling interests. AES Brasil is reported in the Renewables SBU reportable segment. Guaimbê Holding — In January 2022, the Ventus wind complex and AGV solar complex were incorporated by Guaimbê Holding. Guaimbê Holding issued preferred shares representing 3.5% ownership in the subsidiary for total proceeds of $63 million. The transaction decreased the Company’s indirect ownership interest to 35.8%. As the Company maintained control after these transactions, Guaimbê Holding continues to be consolidated by the Company within the Renewables SBU reportable segment. AES Andes — In January 2022, Inversiones Cachagua SpA (“Cachagua”) completed a tender offer for the shares of AES Andes held by minority shareholders for $522 million, net of transaction costs. Upon completion, AES' indirect beneficial interest in AES Andes increased from 67.1% to 98.1%. Through multiple transactions following the tender offer during the first quarter of 2022, Cachagua acquired an additional 0.8% ownership in AES Andes for $13 million, further increasing AES’ indirect beneficial interest to 98.9%. The tender offer and these follow-on transactions resulted in a $169 million decrease to Parent Company Stockholder’s Equity due to a decrease in additional paid-in capital of $93 million and the reclassification of accumulated other comprehensive losses from NCI to AOCL of $76 million. AES Andes is reported in the Energy Infrastructure SBU reportable segment.

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. In our 2022 Form 10-K, the management reporting structure and the Company’s reportable segments were mainly organized by geographic regions. In March 2023, we announced internal management changes as a part of our ongoing strategy to align our business to meet our customers’ needs and deliver on our major strategic objectives. The management reporting structure is now 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. All prior period results have been retrospectively revised to reflect the new segment reporting structure. • 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. During the first quarter of 2023, management began assessing operational performance and making resource allocation decisions using Adjusted EBITDA. Therefore, 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 related to derivative transactions and equity securities; (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; (e) gains, losses and costs due to the early retirement of debt; and (f) net gains at Angamos, one of our businesses in the Energy Infrastructure SBU, associated with the early contract terminations with Minera Escondida and Minera Spence. 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 $379 million and $337 million as of September 30, 2023 and December 31, 2022, respectively. During the nine months ended September 30, 2023 and 2022, we recognized revenue of $30 million and $34 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. As of September 30, 2023, the corresponding receivable balance was $77 million, of which $40 million and $37 million was recorded in Other current assets and Other noncurrent assets , respectively , on the Condensed Consolidated Balance Sheet. A significant financing component of $57 million will be recognized over the life of the payment term as interest income using the effective interest method. 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 September 30, 2023 and December 31, 2022, the Mong Duong loan receivable had a balance of $1.1 billion, net of CECL reserves of $26 million and $28 million, respectively. Of the loan receivable balance, $105 million and $97 million, respectively, was classified as Other current assets , and $990 million and $1 billion, respectively, was classified as Loan receivable on the Condensed Consolidated Balance Sheets.

The Company performed an impairment analysis as of July 31, 2023, and determined that the carrying amounts of the asset groups were not recoverable. The TEG and TEP asset groups were determined to have fair values of $93 million and $94 million, respectively, using the income approach. As a result, the Company recognized pre-tax asset impairment expense of $77 million and $59 million, respectively. TEG and TEP are reported in the Energy Infrastructure SBU reportable segment. Norgener — In May 2023, AES Andes announced its intention to accelerate the retirement of the Norgener coal-fired plant in Chile in order to further advance its decarbonization strategy. Due to this strategic development and the resulting decrease in useful life of the generation facility, the Company performed an impairment analysis as of May 1, 2023, and determined that the carrying amount of the asset group was not recoverable. The Norgener asset group was determined to have a fair value of $24 million, using the income approach. As a result, and since pre-tax losses are limited to the carrying amount of the long-lived assets, the Company recognized pre-tax asset impairment expense of $137 million. Norgener is reported in the Energy Infrastructure SBU reportable segment. Jordan — In November 2020, the Company signed an agreement to sell 26% ownership interest in Amman East and IPP4 for $58 million and as of September 30, 2023, the generation plants were classified as held-for-sale. 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 $43 million and $51 million was recorded during the nine months ended September 30, 2023 and 2022, respectively. See Note 17 —Held-for-Sale for further information. Amman East and IPP4 are reported in the Energy Infrastructure SBU reportable segment.

Business Combinations [Abstract]
Acquisitions	. ACQUISITIONS Petersburg Solar Project — On August 31, 2023, the Company entered into agreements for project development and for the purchase of 100% of the membership in Petersburg Energy Center, LLC, a 250 MW solar and BESS project. The transaction was accounted for as an asset acquisition of variable interest entities that did not meet the definition of a business. The assets acquired and liabilities assumed were recorded at their fair values, which equaled the fair value of the consideration paid of approximately $49 million. Petersburg Solar Project is reported in the Utilities SBU reportable segment. Calhoun — On July 18, 2023, the Company entered into an agreement for the purchase of 100% of the membership interests in Calhoun County Solar Project, LLC., which holds a late development-stage 125 MW solar project. The transaction was accounted for as an asset acquisition of variable interest entities that did not meet the definition of a business. The assets acquired and liabilities assumed were recorded at their fair values, which equaled the fair value of the consideration paid of approximately $64 million, including contingent consideration of $42 million. The estimated fair value of the contingent consideration for Calhoun was determined using probability-weighted discounted cash flows based on internal forecasts, which are considered Level 3 inputs. The probability of achieving the milestone payment used to calculate the acquisition date fair value of the contingent consideration was 99%. Payments under the contingent consideration arrangement are largely binary and thus, a single probability of achieving the milestone was applied in the calculation of fair value.The contingent consideration will be updated quarterly with any prospective changes in fair value recorded through earnings. Calhoun is reported in the Renewables SBU reportable segment. Bellefield — On June 5, 2023, the Company entered into an agreement for the purchase of 100% of the membership interests in the Bellefield projects, consisting of two late development-stage solar and BESS projects of 1 GW each. The transaction was accounted for as an asset acquisition of variable interest entities that did not meet the definition of a business. The Company agreed to make total cash payments including reimbursement of development and equipment costs of approximately $449 million, a portion of which is contingent upon future milestones and price adjustments. In the case that future milestones are not met, the total cash payment will be adjusted accordingly, along with any other purchase price adjustments. The assets acquired and liabilities assumed were recorded at their fair values, which equaled the fair value of the consideration to be paid of approximately $358 million, including cash paid of $165 million, contingent consideration of $165 million, and deferred payments of $28 million. The estimated fair value of the contingent consideration of Bellefield was determined using probability-weighted discounted cash flows based on internal forecasts, which are considered Level 3 inputs. The weighted average probability of achieving the milestone payments used to calculate the acquisition date fair value of the contingent consideration was 91.9%.

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 and nine months ended September 30, 2023 and 2022, where income represents the numerator and weighted average shares represent the denominator. Three Months Ended September 30, 2023 2022 (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 $ 231 670 $ 0.34 $ 421 668 $ 0.63 EFFECT OF DILUTIVE SECURITIES Stock options — — — — 1 — Restricted stock units — 2 — — 2 — Equity units — 40 (0.02) — 40 (0.04) DILUTED EARNINGS PER SHARE $ 231 712 $ 0.32 $ 421 711 $ 0.59 Nine Months Ended September 30, 2023 2022 (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 $ 343 669 $ 0.51 $ 357 668 $ 0.53 EFFECT OF DILUTIVE SECURITIES Stock options — 1 — — 1 — Restricted stock units — 2 — — 2 — Equity units 1 40 (0.03) 1 40 (0.03) DILUTED EARNINGS PER SHARE $ 344 712 $ 0.48 $ 358 711 $ 0.50 The calculation of diluted earnings per share excluded 2 million outstanding stock awards for the three and nine months ended September 30, 2023 and September 30, 2022, which would be anti-dilutive. These stock awards could potentially dilute basic earnings per share in the future. As described in Note 11 —Equity , the Company issued 10,430,500 Equity Units in March 2021 with a total notional value of $1,043 million. Each Equity Unit has a stated amount of $100 and was initially issued as a Corporate Unit, consisting of a 2024 Purchase Contract and a 10% undivided beneficial ownership interest in one share of Series A Preferred Stock. Prior to February 15, 2024, the Series A Preferred Stock may be converted at the option of the holder only in connection with a fundamental change. On and after February 15, 2024, the Series A Preferred Stock may be converted freely at the option of the holder. Upon conversion, the Company will deliver to the holder with respect to each share of Series A Preferred Stock being converted (i) a share of our Series B Preferred Stock, or, solely with respect to conversions in connection with a redemption, cash and (ii) shares of our common stock, if any, in respect of any conversion value in excess of the liquidation preference of the preferred stock being converted. The conversion rate was initially 31.5428 shares of common stock per one share of Series A Preferred Stock, which was equivalent to an initial conversion price of approximately $31.70 per share of common stock. As of September 30, 2023, due to customary anti-dilution provisions, the conversion rate was 31.6465, equivalent to a conversion price of approximately $31.60 per share of common stock. The Series A Preferred Stock and the 2024 Purchase Contracts are being accounted for as one unit of account. In calculating diluted EPS, the Company has applied the if-converted method to determine the impact of the forward purchase feature and considered if there are incremental shares that should be included related to the Series A Preferred conversion value.

Risks and Uncertainties [Abstract]
Unusual Risks and Uncertainties [Table Text Block]	RISKS AND UNCERTAINTIES Puerto Rico — Earlier this year, 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. Additionally, AES Puerto Rico entered into a standstill and forbearance agreement with its noteholders because of the insufficiency of funds to meet the principal and interest obligations on its Series A Bond Loans due and payable on June 1, 2023, and going forward. AES Puerto Rico continues to work with PREPA and its noteholders on these liquidity challenges. Despite these challenges and considering the information available as of the filing date, management believes the carrying amount of our long-lived assets at AES Puerto Rico of $63 million is recoverable as of September 30, 2023. However, it is reasonably possible that the estimate of undiscounted cash flows may change in the near term resulting in the need to write down our long-lived assets in Puerto Rico to fair value.

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.

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. In our 2022 Form 10-K, the management reporting structure and the Company’s reportable segments were mainly organized by geographic regions. In March 2023, we announced internal management changes as a part of our ongoing strategy to align our business to meet our customers’ needs and deliver on our major strategic objectives. The management reporting structure is now 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. All prior period results have been retrospectively revised to reflect the new segment reporting structure. • 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. During the first quarter of 2023, management began assessing operational performance and making resource allocation decisions using Adjusted EBITDA. Therefore, 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 related to derivative transactions and equity securities; (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; (e) gains, losses and costs due to the early retirement of debt; and (f) net gains at Angamos, one of our businesses in the Energy Infrastructure SBU, associated with the early contract terminations with Minera Escondida and Minera Spence. 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.

New Accounting Pronouncements Issued	New Accounting Pronouncements Issued But Not Yet Effective — The following table provides a brief description of recent accounting pronouncements that could have a material impact on the Company’s condensed consolidated financial statements once adopted. Accounting pronouncements not listed below were assessed and determined to be either not applicable or are expected to have no material impact on the Company’s condensed consolidated financial statements. New Accounting Standards Issued But Not Yet Effective ASU Number and Name Description Date of Adoption Effect on the financial statements upon adoption 2023-05 Business Combinations - Joint Venture Formations (Subtopic 805-60): Recognition and Initial Measurement The amendments in this Update address the accounting for contributions made to a joint venture, upon formation, in a joint venture’s separate financial statements. The objectives of the amendments are to (1) provide decision-useful information to investors and other allocators of capital (collectively, investors) in a joint venture’s financial statements and (2) reduce diversity in practice. To reduce diversity in practice and provide decision-useful information to a joint venture’s investors, the Board decided to require that a joint venture apply a new basis of accounting upon formation. By applying a new basis of accounting, a joint venture, upon formation, will recognize and initially measure its assets and liabilities at fair value (with exceptions to fair value measurement that are consistent with the business combinations guidance). The amendments in this Update do not amend the definition of a joint venture (or a corporate joint venture), the accounting by an equity method investor for its investment in a joint venture, or the accounting by a joint venture for contributions received after its formation. The amendments in this Update permit a joint venture to apply the measurement period guidance in Subtopic 805-10 if the initial accounting for a joint venture formation is incomplete by the end of the reporting period in which the formation occurs. Prospectively for all Joint Venture formations with a formation date on or after January 1, 2025. For Joint Ventures formed before January 1, 2025, entities may elect to apply the amendments retrospectively if it has sufficient information. The Company is currently evaluating the impact of adopting the standard on its consolidated financial statements. 2023-06 Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative In U.S. Securities and Exchange Commission (SEC) Release No. 33-10532, Disclosure Update and Simplification, issued August 17, 2018, the SEC referred certain of its disclosure requirements that overlap with, but require incremental information to, generally accepted accounting principles (GAAP) to the FASB for potential incorporation into the Codification. The amendments in this Update are the result of the Board’s decision to incorporate into the Codification 14 of the 27 disclosures referred by the SEC. The amendments in this Update represent changes to clarify or improve disclosure and presentation requirements of a variety of Topics. Many of the amendments allow users to more easily compare entities subject to the SEC’s existing disclosures with those entities that were not previously subject to the SEC’s requirements. Also, the amendments align the requirements in the Codification with the SEC’s regulations. The effective date for each amendment will be the date on which the SEC's removal of that related disclosure becomes effective, with early adoption prohibited. The amendments in this Update should be applied prospectively. The Company will provide the required disclosures on a prospective basis on the date each amendment becomes effective. The Company does not expect ASU 2023-06 will have any impact to our consolidated financial statements.
New Accounting Pronouncements Adopted	New Accounting Pronouncements Adopted in 2023 — The following table provides a brief description of recent accounting pronouncements that had an impact on the Company’s condensed consolidated financial statements. Accounting pronouncements not listed below were assessed and determined to be either not applicable or did not have a material impact on the Company’s condensed consolidated financial statements. New Accounting Standards Adopted ASU Number and Name Description Date of Adoption Effect on the financial statements upon adoption 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers This update is to improve the accounting for acquired revenue contracts with customers in a business combination by addressing diversity in practice and inconsistency related to the following: (1) recognition of an acquired contract liability, and (2) payment terms and their effect on subsequent revenue recognized by the acquirer. Early adoption of the amendments is permitted, including adoption in an interim period. An entity that early adopts in an interim period should apply the amendments (1) retrospectively to all business combinations for which the acquisition date occurs on or after the beginning of the fiscal year that includes the interim period of early application and (2) prospectively to all business combinations that occur on or after the date of initial application. January 1, 2023 The Company adopted this standard on a prospective basis, which is being applied to any business combinations that occur in 2023 or after. The adoption of this ASU did not have a material impact on the Company's consolidated financial statements. 2022-02 Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures ASU 2022-02 amends ASC 326-20-50-6 to require public business entities to disclose gross write-offs recorded in the current period, on a year-to-date basis, by year of origination in the vintage disclosures. This disclosure should cover each of the previous five annual periods starting with the date of the financial statements and, for the annual periods before that, an aggregate total. However, upon adoption of the ASU, an entity would not provide the previous five annual periods of gross write-offs. The FASB decided that disclosure of gross write-offs would instead be applied on a prospective transition basis so that preparers can “build” the five-annual-period disclosure over time. January 1, 2023 The Company adopted this standard on a prospective basis and it did not have a material impact on the financial statements. 2022-04,Liabilities - Supplier Finance Programs (Topic 450-50): Disclosure of Supplier Finance Program Obligations This update is to provide additional information and disclosures about an entity’s use of supplier finance programs to see how these programs will affect an entity’s working capital, liquidity, and cash flows. Entities that use supplier finance programs as the buyer party should disclose (1) the key terms of the payment terms and assets pledged as security or other forms of guarantees provided and (2) the unpaid amount outstanding, a description of where those obligations are presented on the balance sheet, and a rollforward of those obligations during the annual period. January 1, 2023, except for the rollforward information, which is effective for fiscal years beginning after December 15, 2023. The ASU only requires disclosures related to the Company's supplier finance programs and does not affect the recognition, measurement, or presentation of supplier finance program obligations on the balance sheet or cash flow statement. The Company adopted the new disclosure requirements in the first quarter of 2023, except for the annual requirement to disclose rollforward information, which the Company expects to adopt and present prospectively beginning in the 2024 annual financial statements. 2023-03, Presentation of Financial Statements (Topic 205), This Accounting Standards Update amends various SEC paragraphs pursuant to SEC Staff Accounting Bulletin No. 120, SEC Staff Announcement at the March 24, 2022 EITF Meeting, and Staff Accounting Bulletin Topic 6.B, Accounting Series Release 280—General Revision of Regulation S-X: Income or Loss Applicable to Common Stock. The amendments in this Update are effective for all entities upon issuance of this Update. June 30, 2023 The adoption of this ASU did not have a material impact on the Company’s consolidated financial statements.

The Company concluded that the Equity Units should be accounted for as one unit of account based on the economic linkage between the 2024 Purchase Contracts and the Series A Preferred Stock, as well as the Company's assessment of the applicable accounting guidance relating to combining freestanding instruments. The Equity Units represent mandatorily convertible preferred stock. Accordingly, the shares associated with the combined instrument are reflected in diluted earnings per share using the if-converted method. In conjunction with the issuance of the Equity Units, the Company received approximately $1 billion in proceeds, net of underwriting costs and commissions, before offering expenses. The proceeds for the issuance of 1,043,050 shares are attributed to the Series A Preferred Stock for $838 million and $205 million for the present value of the quarterly payments due to holders of the 2024 Purchase Contracts ("Contract Adjustment Payments"). The proceeds were used for the development of the AES renewable businesses, U.S. utility businesses, LNG infrastructure, and for other developments determined by management. The Series A Preferred Stock will initially not bear any dividends and the liquidation preference of the convertible preferred stock will not accrete. The Series A Preferred Stock has no maturity date and will remain outstanding unless converted by holders or redeemed by the Company. Holders of the shares of the convertible preferred stock will have limited voting rights. The Series A Preferred Stock is pledged as collateral to support holders’ purchase obligations under the 2024 Purchase Contracts and can be remarketed. In connection with any successful remarketing, the Company may increase the dividend rate, increase the conversion rate, and modify the earliest redemption date for the convertible preferred stock. After any successful remarketing in connection with which the dividend rate on the convertible preferred stock is increased, the Company will pay cumulative dividends on the convertible preferred stock, if declared by the board of directors, quarterly in arrears from the applicable remarketing settlement date. Holders of Corporate Units may create Treasury Units or Cash Settled Units from their Corporate Units as provided in the Purchase Contract Agreement by substituting Treasury securities or cash, respectively, for the Convertible Preferred Stock comprising a part of the Corporate Units. The Company may not redeem the Series A Preferred Stock prior to March 22, 2024. At the election of the Company, on or after March 22, 2024, the Company may redeem for cash, all or any portion of the outstanding shares of the Series A Preferred Stock at a redemption price equal to 100% of the liquidation preference, plus any accumulated and unpaid dividends. The 2024 Purchase Contracts obligate the holders to purchase, on February 15, 2024, for a price of $100 in cash, a maximum number of 57,407,386 shares of the Company’s common stock (subject to customary anti-dilution adjustments). The 2024 Purchase Contract holders may elect to settle their obligation early, in cash. The Series A Preferred Stock is pledged as collateral to guarantee the holders’ obligations to purchase common stock under the terms of the 2024 Purchase Contracts. The initial settlement rate determining the number of shares that each holder must purchase will not exceed the maximum settlement rate and is determined over a market value averaging period preceding February 15, 2024. The initial maximum settlement rate of 3.864 was calculated using an initial reference price of $25.88, equal to the last reported sale price of the Company’s common stock on March 4, 2021. As of September 30, 2023, due to the customary anti-dilution provisions, the maximum settlement rate was 3.8768, equivalent to a reference price of $25.79. If the applicable market value of the Company’s common stock is less than or equal to the reference price, the settlement rate will be the maximum settlement rate; and if the applicable market value of common stock is greater than the reference price, the settlement rate will be a number of shares of the Company’s common stock equal to $100 divided by the applicable market value. Upon successful remarketing of the Series A Preferred Stock (“Remarketed Series A Preferred Stock”), the Company expects to receive additional cash proceeds of $1 billion and issue shares of Remarketed Series A Preferred Stock. The Company pays Contract Adjustment Payments to the holders of the 2024 Purchase Contracts at a rate of 6.875% per annum, payable quarterly in arrears on February 15, May 15, August 15, and November 15, commencing on May 15, 2021. The $205 million present value of the Contract Adjustment Payments at inception reduced the Series A Preferred Stock. As each quarterly Contract Adjustment Payment is made, the related liability is reduced and the difference between the cash payment and the present value will accrete to interest expense, approximately $5 million over the three-year term. As of September 30, 2023, the present value of the Contract Adjustment Payments was $36 million. The holders can settle the purchase contracts early, for cash, subject to certain exceptions and conditions in the prospectus supplement. Upon early settlement of any purchase contracts, the Company will deliver the number of shares of its common stock equal to 85% of the number of shares of common stock that would have otherwise been deliverable. Equity Transactions with Noncontrolling Interests AES Clean Energy Tax Equity Partnerships — The majority of solar projects under AES Clean Energy have been financed with tax equity structures, in which tax equity investors receive a portion of the economic attributes of the facilities, including tax attributes, that vary over the life of the projects. During the nine months ended September 30, 2023 and 2022, AES Clean Energy Development and AES Renewable Holdings, through multiple transactions, sold noncontrolling interests in project companies to tax equity partners, resulting in increases to NCI of $292 million and $210 million, respectively. In the third quarter of 2023, AES Renewable Holdings completed buyouts of tax equity partners at Buffalo Gap I, Buffalo Gap II and six other project companies, resulting in a decrease to NCI of $45 million and an increase to additional paid-in capital of $34 million. AES Clean Energy Development and AES Renewable Holdings are reported in the Renewables SBU reportable segment. Chile Renovables — Under its renewable partnership agreement with Global Infrastructure Management, LLC (“GIP”), AES Andes will contribute a specified pipeline of renewable development projects to Chile Renovables as the projects reach commercial operations, and GIP may make additional contributions to maintain its 49% ownership interest. During the nine months ended September 30, 2022 and 2023, AES Andes completed the sale of the following projects to Chile Renovables (in millions): Business Transaction Period Sale Price Increase to Noncontrolling Interests Increase (Decrease) to Additional Paid-In Capital Andes Solar 2a January 2022 $ 37 $ 28 $ 9 Los Olmos June 2022 80 68 12 Campo Lindo September 2023 50 59 (9) As the Company maintained control after these transactions, Chile Renovables continues to be consolidated by the Company within the Energy Infrastructure SBU reportable segment. AES Panama — In September 2023, AES Latin America completed the sale of its interest in the Grupo Energía Gas Panamá joint venture to AES Panama, a 49%-owned consolidated subsidiary. See Note 6— Investments in and Advances to Affiliates for further information. As a result of the transaction, AES Panama received $42 million from noncontrolling interest holders and the Company reclassified accumulated other comprehensive income from AOCL to NCI of $23 million. AES Panama is reported in the Renewables SBU reportable segment however the investment in Grupo Energía Gas Panamá is reported in the Energy Infrastructure SBU reportable segment. AES Brasil — In September 2022, AES Brasil commenced a private placement offering for its existing shareholders to subscribe for up to 107 million newly issued shares. AES Holdings Brasil Ltda. subscribed for 54 million shares and noncontrolling interest holders subscribed for 53 million shares, thereby increasing AES’ indirect beneficial interest in AES Brasil to 47.4%. AES Brasil received $77 million from noncontrolling interest holders during the third quarter of 2022, prior to the issuance of the shares in October 2022. Since the consideration received was nonrefundable, the impact was recorded in noncontrolling interests. AES Brasil is reported in the Renewables SBU reportable segment. Guaimbê Holding — In January 2022, the Ventus wind complex and AGV solar complex were incorporated by Guaimbê Holding. Guaimbê Holding issued preferred shares representing 3.5% ownership in the subsidiary for total proceeds of $63 million. The transaction decreased the Company’s indirect ownership interest to 35.8%. As the Company maintained control after these transactions, Guaimbê Holding continues to be consolidated by the Company within the Renewables SBU reportable segment. AES Andes — In January 2022, Inversiones Cachagua SpA (“Cachagua”) completed a tender offer for the shares of AES Andes held by minority shareholders for $522 million, net of transaction costs. Upon completion, AES' indirect beneficial interest in AES Andes increased from 67.1% to 98.1%. Through multiple transactions following the tender offer during the first quarter of 2022, Cachagua acquired an additional 0.8% ownership in AES Andes for $13 million, further increasing AES’ indirect beneficial interest to 98.9%. The tender offer and these follow-on transactions resulted in a $169 million decrease to Parent Company Stockholder’s Equity due to a decrease in additional paid-in capital of $93 million and the reclassification of accumulated other comprehensive losses from NCI to AOCL of $76 million. AES Andes is reported in the Energy Infrastructure SBU reportable segment.
