Organization, Consolidation and Presentation of Financial Statements [Abstract]
FINANCIAL STATEMENT PRESENTATION	FINANCIAL STATEMENT PRESENTATION 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. All intercompany transactions and balances have been eliminated in consolidation. 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 and six months ended June 30, 2020 are not necessarily indicative of expected results for the year ending December 31, 2020 . The accompanying condensed consolidated financial statements are unaudited and should be read in conjunction with the 2019 audited consolidated financial statements and notes thereto, which are included in the 2019 Form 10-K filed with the SEC on February 27, 2020 (the “ 2019 Form 10-K”). Cash, Cash Equivalents, and Restricted Cash — The following table provides a summary of cash, cash equivalents, and restricted cash amounts reported on the Condensed Consolidated Balance Sheet that reconcile to the total of such amounts as shown on the Condensed Consolidated Statements of Cash Flows (in millions): June 30, 2020 December 31, 2019 Cash and cash equivalents $ 1,417 $ 1,029 Restricted cash 364 336 Debt service reserves and other deposits 326 207 Cash, Cash Equivalents, and Restricted Cash $ 2,107 $ 1,572 New Accounting Pronouncements Adopted in 2020 — The following table provides a brief description of recent accounting pronouncements that had an impact on the Company’s 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 consolidated financial statements. New Accounting Standards Adopted ASU Number and Name Description Date of Adoption Effect on the financial statements upon adoption 2016-02, 2018-01, 2018-10, 2018-11, 2018-20, 2019-01, Leases (Topic 842) ASC 842 was adopted by sPower on January 1, 2020. sPower was not required to adopt ASC 842 using the public adoption date, as sPower is an equity method investee that meets the definition of a public business entity only by virtue of the inclusion of its summarized financial information in the Company’s SEC filings. January 1, 2020 The adoption of this standard resulted in a $4 million decrease to accumulated deficit attributable to the AES Corporation stockholders’ equity. 2016-13, 2018-19, 2019-04, 2019-05, 2019-10, 2019-11, 2020-02, 2020-03, Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments See discussion of the ASU below. January 1, 2020 See impact upon adoption of the standard below. ASC 326 — Financial Instruments — Credit Losses On January 1, 2020, the Company adopted ASC 326 Financial Instruments — Credit Losses and its subsequent corresponding updates (“ASC 326”). The new standard updates the impairment model for financial assets measured at amortized cost, known as the Current Expected Credit Loss (“CECL”) model. For trade and other receivables, held-to-maturity debt securities, loans, and other instruments, entities are required to use a new forward-looking "expected loss" model that generally results in the earlier recognition of an allowance for credit losses. For available-for-sale debt securities with unrealized losses, entities measure credit losses as it was done under previous GAAP, except that unrealized losses due to credit-related factors are now recognized as an allowance on the balance sheet with a corresponding adjustment to earnings in the income statement. The Company applied the modified retrospective method of adoption for ASC 326. Under this transition method, the Company applied the transition provisions starting at the date of adoption. The cumulative effect of the adoption of ASC 326 on our January 1, 2020 Condensed Consolidated Balance Sheet was as follows (in millions): Condensed Consolidated Balance Sheet Balance at December 31, 2019 Adjustments Due to ASC 326 Balance at January 1, 2020 Assets Accounts receivable, net of allowance for doubtful accounts of $20 $ 1,479 $ — $ 1,479 Other current assets (1) 802 (2 ) 800 Deferred income taxes 156 9 165 Loan receivable, net of allowance of $32 1,351 (32 ) 1,319 Other noncurrent assets (2) 1,635 (30 ) 1,605 Liabilities and Equity Accumulated deficit $ (692 ) $ (39 ) $ (731 ) Noncontrolling interests 2,233 (16 ) 2,217 _________________________ (1) Other current assets include the short-term portion of the Mong Duong loan receivable. (2) Other noncurrent assets include Argentina financing receivables. Mong Duong — The Mong Duong II power plant in Vietnam is the primary driver of changes in credit reserves under the new standard. This plant is operated under a build, operate, and transfer (“BOT”) contract and will be transferred to the Vietnamese government after the completion of a 25-year PPA. A loan receivable was recognized in 2018 upon the adoption of ASC 606 in order to account for the future expected payments for the construction performance obligation portion of the BOT contract. As the payments for the construction performance obligation occur over a 25-year term, a significant financing element was determined to exist which is accounted for under the effective interest rate method. Historically, the Company has not incurred any losses on this arrangement, of which no directly comparable assets exist in the market. In order to determine expected credit losses under ASC 326 arising from this $1.4 billion loan receivable as of January 1, 2020, the Company considered average historical default and recovery rates on similarly rated sovereign bonds, which formed an initial basis for developing a probability of default, net of expected recoveries, to be applied as a key credit quality indicator for this arrangement. A resulting estimated loss rate of 2.4% was applied to the weighted-average remaining life of the loan receivable, after adjustments for certain asset-specific characteristics, including the Company’s status as a large foreign direct investor in Vietnam, Mong Duong’s status as critical energy infrastructure in Vietnam, and cash flows from the operations of the plant, which are under the Company’s control until the end of the BOT contract. As a result of this analysis, the Company recognized an opening CECL reserve of $34 million as an adjustment to Accumulated deficit and Noncontrolling interests as of January 1, 2020. Argentina — Exposure to CAMMESA, the administrator of the wholesale energy market in Argentina, is the driver of credit reserves in Argentina. As discussed in Note 7 of the Company’s 2019 Form 10-K, the Company has credit exposures through the FONINVEMEM Agreements, other agreements related to resolutions passed by the Argentine government in which AES Argentina will receive compensation for investments in new generation plants and technologies, as well as regular accounts receivable balances. The timing of collections depends on corresponding agreements and collectability of these receivables are assessed on an ongoing basis. Collection of the principal and interest on these receivables is subject to various business risks and uncertainties, including, but not limited to, the continued operation of power plants which generate cash for payments of these receivables, regulatory changes that could impact the timing and amount of collections, and economic conditions in Argentina. The Company monitors these risks, including the credit ratings of the Argentine government, on a quarterly basis to assess the collectability of these receivables. Historically, the Company has not incurred any credit-related losses on these receivables. In order to determine expected credit losses under ASC 326, the Company considered historical default probabilities utilizing similarly rated sovereign bonds and historic recovery rates for Argentine government bond defaults. This information formed an initial basis for developing a probability of default, net of expected recoveries, to be applied as a key credit quality indicator across the underlying financing receivables. A resulting estimated weighted average loss rate of 41.2% was applied to the remaining balance of these receivables, after adjustments for certain asset-specific characteristics, including AES Argentina’s role in providing critical energy infrastructure to Argentina, our history of collections on these receivables, and the average term that the receivables are expected to be outstanding. As a result of this analysis, the Company recognized an opening CECL reserve of $29 million as an adjustment to Accumulated deficit as of January 1, 2020. Other financial assets — Application of ASC 326 to the Company’s $1.5 billion of trade accounts receivable and $326 million of available-for-sale debt securities at January 1, 2020 did not result in any material adjustments, primarily due to the short-term duration and high turnover of these financial assets. Additionally, a large portion of our trade accounts receivables and amounts reserved for doubtful accounts under legacy GAAP arise from arrangements accounted for as an operating lease under ASC 842, which are excluded from the scope of ASC 326. As discussed in Note 7 of the Company’s 2019 Form 10-K, AES Gener recorded $33 million of noncurrent receivables pertaining to revenues recognized on regulated energy contracts that were impacted by the Stabilization Fund created by the Chilean government in October 2019. It is expected that these noncurrent receivables will be collected prior to December 31, 2027. However, given the investment grade rating of Chile and the history of zero credit losses for regulated customers, management determined that no incremental CECL reserves were required to be recognized as of January 1, 2020. The following table represents the rollforward of the allowance for credit losses from January 1, 2020 to June 30, 2020 (in millions): Rollforward of CECL Reserves by Portfolio Segment Reserve at January 1, 2020 Current Period Provision Write-offs charged against allowance Recoveries Collected Foreign Exchange Reserve at June 30, 2020 Accounts Receivable (1) $ 4 $ 10 $ (7 ) $ 5 $ — $ 12 Mong Duong Loan Receivable 34 — — (1 ) — 33 Argentina Receivables 29 2 — (1 ) (4 ) 26 Other 1 — — — — 1 Total CECL Reserves $ 68 $ 12 $ (7 ) $ 3 $ (4 ) $ 72 _____________________________ (1) Excludes operating lease receivable allowances and contractual dispute allowances of $16 million and $6 million as of January 1 , 2020 and June 30, 2020 , respectively. Those reserves are not in scope under ASC 326. 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 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 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 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting The standard provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions that reference to LIBOR or another reference rate expected to be discontinued by reference rate reform. This standard is effective for a limited period of time (March 12, 2020 - December 21, 2022). Effective for all entities as of March 12, 2020 through December 31, 2022. The Company is currently evaluating the impact of adopting the standard on its consolidated financial statements. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting For Income Taxes The standard removes certain exceptions for recognizing deferred taxes for investments, performing intra-period allocation and calculating income taxes in interim periods. It also adds guidance to reduce complexity in certain areas, including recognizing deferred taxes for tax goodwill and allocating taxes to members of a consolidated group. Transition Method: various January 1, 2021. Early adoption is permitted. The Company is currently evaluating the impact of adopting the standard on its consolidated financial statements.

Asset Retirement Obligation Disclosure [Abstract]
Asset Retirement Obligation Disclosure [Text Block]	ASSET RETIREMENT OBLIGATIONS The Company uses the cost approach to determine the initial value of ARO liabilities, which is estimated by discounting expected cash outflows to their present value using market-based rates at the initial recording of the liabilities. Cash outflows are based on the approximate future disposal costs as determined by market information, historical information or other management estimates. Subsequent downward revisions of ARO liabilities are discounted using the market-based rates that existed when the liability was initially recognized. During the six months ended June 30, 2019 , the Company decreased the asset retirement obligation at DPL by $23 million , resulting in a reduction to Cost of Sales

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 2019 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: June 30, 2020 December 31, 2019 Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Assets DEBT SECURITIES: Available-for-sale: Certificates of deposit $ — $ 360 $ — $ 360 $ — $ 326 $ — $ 326 EQUITY SECURITIES: Mutual funds 23 48 — 71 22 61 — 83 DERIVATIVES: Interest rate derivatives — — — — — 31 — 31 Foreign currency derivatives — 20 76 96 — 17 93 110 Commodity derivatives — 81 3 84 — 28 2 30 Total derivatives — assets — 101 79 180 — 76 95 171 TOTAL ASSETS $ 23 $ 509 $ 79 $ 611 $ 22 $ 463 $ 95 $ 580 Liabilities DERIVATIVES: Interest rate derivatives $ — $ 507 $ 286 $ 793 $ — $ 144 $ 184 $ 328 Cross-currency derivatives — 22 23 45 — 10 11 21 Foreign currency derivatives — 46 — 46 — 44 — 44 Commodity derivatives — 63 2 65 — 29 2 31 Total derivatives — liabilities — 638 311 949 — 227 197 424 TOTAL LIABILITIES $ — $ 638 $ 311 $ 949 $ — $ 227 $ 197 $ 424 As of June 30, 2020 , 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 six months ended June 30, 2019 , and as of January 1, 2020, credit-related impairments are recognized in earnings under ASC 326. See Note 1— Financial Statement Presentation for further information. 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 June 30, Six Months Ended June 30, 2020 2019 2020 2019 Gross proceeds from sale of available-for-sale securities $ 55 $ 176 $ 313 $ 324 The following tables present a reconciliation of net derivative assets and liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the three and six months ended June 30, 2020 and 2019 (presented net by type of derivative in millions).

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). As the Company applied the modified retrospective method of adoption for ASC 326 effective January 1, 2020, CECL reserves are included in the receivable balance as of June 30, 2020 . See Note 1 — Financial Statement Presentation for further information. June 30, 2020 December 31, 2019 Gross Receivable Allowance Net Receivable Receivable Chile $ 88 $ — $ 88 $ 33 Argentina 56 12 44 64 U.S. 18 — 18 — Other 13 — 13 12 Total $ 175 $ 12 $ 163 $ 109 Chile — AES Gener has recorded noncurrent receivables pertaining to revenues recognized on regulated energy contracts that were impacted by the Stabilization Fund created by the Chilean government in October 2019. Historically, the government updated the prices for these contracts every six months to reflect the indexation the contracts have to exchange rates and commodities prices. The Stabilization Fund does 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 into pricing in 2023. Consequently, costs incurred in excess of the July 1, 2019 price will be accumulated and borne by generators. It is expected that these noncurrent receivables will be collected prior to December 31, 2027. A portion of the Chile noncurrent receivables relates to the extension of existing PPAs with the addition of renewable energy, resulting in a discount for the remaining original contract period and additional quantities for an extended period. Argentina — Collection of the principal and interest on these receivables is subject to various business risks and uncertainties, including, but not limited to, the operation of power plants which generate cash for payments of these receivables, regulatory changes that could impact the timing and amount of collections, and economic conditions in Argentina. The Company monitors these risks, including the credit ratings of the Argentine government, on a quarterly basis to assess the collectability of these receivables. The Company accrues interest on these receivables once the recognition criteria have been met. The Company’s collection estimates are based on assumptions that it believes to be reasonable, but are inherently uncertain. Actual future cash flows could differ from these estimates. United States — In March 2020, the Company completed the sale and leaseback of land held by AES Redondo Beach, a gas-fired generating facility in California. A portion of the sale proceeds were deferred over a future period. It is expected that the noncurrent receivables will be collected by December 2021. See Note 18 — Held-for-Sale and Dispositions for further information about the sale.

A calculation of the fair value of the Company’s investment in OPGC was required to evaluate whether there was a loss in the carrying value of the investment. Based on management’s estimate of fair value of $212 million , the Company had recognized an other-than-temporary impairment of $92 million in December 2019. In March 2020, management’s updated estimate of fair value was $152 million and the Company then recognized an additional other-than-temporary impairment of $43 million due to the current economic slowdown. In June 2020, the Company agreed to sell its entire 49% stake in OPGC resulting in an additional other-than-temporary impairment of $158 million . Total other-than-temporary impairment for the six months ended June 30, 2020 was $201 million recognized in Other non-operating expense . The sale is expected to close in the first quarter of 2021. The OPGC equity method investment is reported in the Eurasia SBU reportable segment. sPower — In April 2019, the Company closed on the sale of approximately 48% of its interest in a portfolio of sPower’s operating assets for $173 million , subject to customary purchase price adjustments, of which $58 million was used to pay down debt at sPower. This sale resulted in a pre-tax gain on sale of business interests of $28 million . After the sale, the Company’s ownership interest in this portfolio of sPower’s operating assets decreased from 50% to approximately 26% . The sPower equity method investment is reported in the US and Utilities SBU reportable segment.

Debt Disclosure [Abstract]
DEBT	DEBT Recourse Debt During the first quarter of 2020, the Company drew $840 million on revolving lines of credit at the Parent Company, of which approximately $250 million was used to enhance our liquidity position due to the uncertain economic conditions surrounding the COVID-19 pandemic and the remaining $590 million was used for other general corporate purposes. In the second quarter of 2020, the Parent Company repaid approximately $350 million on these revolving lines of credit. As of June 30, 2020 , we had approximately $455 million of outstanding indebtedness on the Parent Company credit facility at a weighted average interest rate of 1.88% . In May 2020, the Company issued $900 million aggregate principal of 3.30% senior secured notes due in 2025 and $700 million of 3.95% senior secured notes due in 2030 . The Company used the net proceeds from these issuances to purchase via tender offer a portion of the 4.00% senior notes due in 2021 , the 4.50% senior notes due in 2023 , and the 4.875% senior notes due in 2023 . Subsequent to the tender offers, the Company redeemed the remaining balance of its 4.00% and 4.875% senior notes due in 2021 and 2023 , respectively, and $7 million of the remaining 4.50% senior notes due in 2023 .

In Puerto Rico, the subsidiary non-recourse debt defaults were triggered by failure to comply with covenants or other requirements contained in the non-recourse debt documents due to the bankruptcy of the offtaker. 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.

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 15 years . The following table summarizes the Parent Company’s contingent contractual obligations as of June 30, 2020 . 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 Amount (in millions) Number of Agreements Maximum Exposure Range for Each Agreement (in millions) Guarantees and commitments $ 1,243 63 $0 — 157 Letters of credit under the unsecured credit facility 238 5 $1 — 211 Letters of credit under the senior secured credit facility 27 30 $0 — 6 Total $ 1,508 98 During the six months ended June 30, 2020 , 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 each of the periods ended June 30, 2020 and December 31, 2019 , the Company recognized liabilities of $4 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 June 30, 2020 . 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 $31 million and $55 million as of June 30, 2020 and December 31, 2019 , 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 June 30, 2020 . 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 $265 million and $313 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]
Leases of Lessor Disclosure [Text Block]	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 payments 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 payments from such contracts are recognized as lease revenue on a straight-line basis over the lease term, whereas variable lease payments are recognized when earned. The following table presents lease revenue from operating leases in which the Company is the lessor for the six months ended June 30, 2020 : Three Months Ended June 30, Six Months Ended June 30, Lease Income 2020 2019 2020 2019 Total Lease Revenue $ 153 $ 155 $ 288 $ 308 Less: Variable Lease Payments 23 24 34 36 Total Non-Variable Lease Revenue $ 130 $ 131 $ 254 $ 272 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 June 30, 2020 . 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 June 30, 2020 for the remainder of 2020 through 2024 and thereafter (in millions): Future Cash Receipts for Sales-Type Leases Operating Leases 2020 $ 1 $ 255 2021 2 475 2022 2 459 2023 2 396 2024 2 396 Thereafter 38 1,425 Total $ 47 $ 3,406 Less: Imputed interest (25 ) Present value of total lease receipts $ 22

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 and is mainly organized by geographic regions, which provides a socio-political-economic understanding of our business. The management reporting structure is organized by four SBUs led by our President and Chief Executive Officer: US and Utilities, South America, MCAC, and Eurasia SBUs. 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. Corporate and Other — Included in “Corporate and Other” are the results of the AES self-insurance company and certain equity affiliates, 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 PTC as its primary segment performance measure. Adjusted PTC, a non-GAAP measure, is defined by the Company as pre-tax income from continuing operations attributable to The AES Corporation excluding gains or losses of the consolidated entity 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) costs directly associated with a major restructuring program, including, but not limited to, workforce reduction efforts, relocations, and office consolidation. Adjusted PTC also includes net equity in earnings of affiliates on an after-tax basis adjusted for the same gains or losses excluded from consolidated entities. The Company has concluded that Adjusted PTC 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 complexity, the Company concluded that Adjusted PTC 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 PTC are presented before inter-segment eliminations, which includes the effect of intercompany transactions with other segments except for interest, 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.

Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	INCOME TAXES The Company’s provision for income taxes is based on the estimated annual effective tax rate, plus discrete items. The effective tax rates for the three and six months ended June 30, 2020 were 108% and 48% , respectively. The effective tax rates for the three and six months ended June 30, 2019 were 48% and 36% , respectively. The difference between the Company’s effective tax rates for the 2020 and 2019 periods and the U.S. statutory tax rate of 21% related primarily to U.S. taxes on foreign earnings, foreign tax rate differentials, the impacts of foreign currency fluctuations at certain foreign subsidiaries, nondeductible expenses, and valuation allowance. The impact of foreign currency devaluation in Mexico was approximately $13 million of discrete tax benefit for the six months ended June 30, 2020 . The Company recognized discrete tax expense of approximately $13 million and $21 million as a result of incremental capitalized interest in Chile for the three and six months ended June 30, 2020 , respectively. Additionally, the Company recognized discrete tax expense of approximately $25 million as a result of incremental deferred taxes relating to DPL for the three and six months ended June 30, 2020 .

DISPOSITIONS AND HELD-FOR-SALE BUSINESSES	HELD-FOR-SALE AND DISPOSITIONS Held-for-Sale Itabo — In June 2020, the Company entered into an agreement to sell its 43% ownership interest in Itabo, a coal-fired plant and gas turbine in Dominican Republic, for $101 million . The sale is subject to regulatory approval and is expected to close in the fourth quarter of 2020. As of June 30, 2020 , Itabo 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 the Itabo facility as of June 30, 2020 was $194 million . Itabo is reported in the MCAC SBU reportable segment. Jordan — In February 2019, the Company entered into an agreement to sell its 36% ownership interest in two generation plants, IPP1 and IPP4, and a solar plant in Jordan. In December 2019, the original sales agreement expired, and in April 2020, one of the potential buyers withdrew from the transaction due to the uncertain economic conditions surrounding the COVID-19 pandemic. The Company continues with an active process to complete the sale of its controlling interest in IPP1 and IPP4 and believes the sale remains probable. However, as of June 30, 2020 , the solar plant no longer met the held-for-sale criteria. As such, the solar plant was reclassified as held and used as of June 30, 2020 . The generation plants remain classified as held-for-sale, but do not meet the criteria to be reported as discontinued operations. On a consolidated basis, the carrying value of the plants held-for-sale as of June 30, 2020 was $153 million . Jordan is reported in the Eurasia SBU reportable segment. Pre-tax income attributable to AES of businesses held-for-sale was as follows: Three Months Ended June 30, Six Months Ended June 30, (in millions) 2020 2019 2020 2019 Itabo $ 8 $ 6 $ 19 $ 14 Jordan 5 5 10 8 Total $ 13 $ 11 $ 29 $ 22 Dispositions Kazakhstan Hydroelectric — Affiliates of the Company (the “Affiliates”) previously operated Shulbinsk HPP and Ust-Kamenogorsk HPP (the “HPPs”), two hydroelectric plants in Kazakhstan, under a concession agreement with the Republic of Kazakhstan (“ROK”). In April 2017, the ROK initiated the process to transfer these plants back to the ROK. The ROK indicated that arbitration would be necessary to determine the correct Return Share Transfer Payment ("RST") and, rather than paying the Affiliates, deposited the RST into an escrow account. In exchange, the Affiliates transferred 100% of the shares in the HPPs to the ROK, under protest and with a full reservation of rights. In February 2018, the Affiliates initiated the arbitration process in international court to recover at least $75 million of the RST placed in escrow, based on the September 30, 2017 RST calculation. In May 2020, the arbitrator issued a final decision in favor of the Affiliates, awarding the Affiliates a net amount of damages of approximately $45 million , which has been collected. AES recorded the remaining $30 million as a loss on sale during the quarter ended June 30, 2020 . Prior to their transfer, the Kazakhstan HPPs were reported in the Eurasia SBU reportable segment. Redondo Beach Land — In March 2020, the Company completed the sale of land held by AES Redondo Beach, a gas-fired generating facility in California. The land’s carrying value was $24 million , resulting in a pre-tax gain on sale of $41 million , reported in Other income on the Condensed Consolidated Statement of Operations. AES Redondo Beach will lease back the land from the purchaser for the remainder of the generation facility’s useful life. Redondo Beach is reported in the US and Utilities SBU reportable segment. Kilroot and Ballylumford — In June 2019, the Company completed the sale of its entire 100% interest in the Kilroot coal and oil-fired plant and energy storage facility and the Ballylumford gas-fired plant in the United Kingdom for $118 million , resulting in a pre-tax loss on sale of $33 million primarily due to the write-off of cumulative translation adjustments and accumulated other comprehensive income balances. The sale did not meet the criteria to be reported as discontinued operations. Prior to the sale, Kilroot and Ballylumford were reported in the Eurasia SBU reportable segment. See Note 16 —Asset Impairment Expense for further information. Shady Point — In May 2019, the Company completed the sale of Shady Point, a U.S. coal-fired generating facility, for $29 million . The sale did not meet the criteria to be reported as discontinued operations. Prior to its sale, Shady Point was reported in the US and Utilities SBU reportable segment. Excluding any impairment charges or gain/loss on sale, pre-tax loss attributable to AES of disposed businesses was as follows: Three Months Ended June 30, Six Months Ended June 30, (in millions) 2019 2019 Kilroot and Ballylumford $ (5 ) $ (1 ) Shady Point (2 ) (3 ) Total $ (7 ) $ (4 )

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 and stock options. The effect of such potential common stock is computed using the treasury stock method. 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 six months ended June 30, 2020 and 2019 , where income represents the numerator and weighted average shares represent the denominator. Three Months Ended June 30, 2020 2019 (in millions, except per share data) Loss Shares $ per Share Income Shares $ per Share BASIC EARNINGS (LOSS) PER SHARE Income (loss) from continuing operations attributable to The AES Corporation common stockholders $ (86 ) 665 $ (0.13 ) $ 16 664 $ 0.02 EFFECT OF DILUTIVE SECURITIES Restricted stock units — — — — 3 — DILUTED EARNINGS (LOSS) PER SHARE $ (86 ) 665 $ (0.13 ) $ 16 667 $ 0.02 Six Months Ended June 30, 2020 2019 (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 $ 58 665 $ 0.09 $ 170 663 $ 0.26 EFFECT OF DILUTIVE SECURITIES Stock options — 1 — — 1 — Restricted stock units — 2 — — 3 — DILUTED EARNINGS PER SHARE $ 58 668 $ 0.09 $ 170 667 $ 0.26 The calculation of diluted earnings per share excluded 2 million outstanding stock awards for the six months ended June 30, 2020 , and 1 million outstanding stock awards for the three and six months ended June 30, 2019 , which would be anti-dilutive. These stock awards could potentially dilute basic earnings per share in the future. For the three months ended June 30, 2020 , the calculation of diluted earnings per share excluded 5 million outstanding stock awards because their impact would be anti-dilutive given the loss from continuing operations. These stock awards could potentially dilute basic earnings per share in the future. Had the Company generated income, 2 million potential shares of common stock related to the stock awards would have been included in diluted weighted-average shares outstanding.

Unusual Risk or Uncertainty [Line Items]
Unusual Risks and Uncertainties [Table Text Block]	RISKS AND UNCERTAINTIES COVID-19 Pandemic — The COVID-19 pandemic has severely impacted global economic activity, including electricity and energy consumption, and caused significant volatility and negative pressure in financial markets. The global impact of the outbreak has been rapidly evolving and many countries, including the United States, have reacted by instituting quarantines, mandating business and school closures, and restricting travel. For the three and six months ended June 30, 2020 , COVID-19 had a moderate impact on the financial results and operations of the Company, as the economic impact of the pandemic was reflected throughout the second quarter. The magnitude and duration of the COVID-19 pandemic is unknown at this time and may have material and adverse effects on our results of operations, financial condition and cash flows in future periods. Goodwill — The Company considers a reporting unit at risk of impairment when its fair value does not exceed its carrying amount by more than 10% . During the annual goodwill impairment test performed as of October 1, 2019, the Company determined that the fair value of its Gener reporting unit exceeded its carrying value by 3% . Therefore, Gener's $868 million goodwill balance is considered "at risk", largely due to the Chilean Government's announcement to phase out coal generation by 2040, and a decline in long-term energy prices. Given the uncertainties in the global market caused by the COVID-19 pandemic, the Company assessed whether current events or circumstances indicated it was more likely than not the fair value of the Gener reporting unit was reduced below its carrying amount in the second quarter of 2020. After assessing the relevant factors, the Company determined there was no triggering event requiring a reassessment of goodwill impairment as of June 30, 2020 . While the duration and severity of the impacts of the COVID-19 pandemic remain unknown, further deterioration in the global market could result in changes to assumptions utilized in the goodwill assessment. The Company monitors its reporting units at risk of impairment for interim impairment indicators, and believes that the estimates and assumptions used in the calculations are reasonable as of June 30, 2020 . Should the fair value of any of the Company’s reporting units fall below its carrying amount because of reduced operating performance, market declines, changes in the discount rate, regulatory changes, or other adverse conditions, goodwill impairment charges may be necessary in future periods.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Accounting Standards Update and Change in Accounting Principle [Table Text Block]	New Accounting Pronouncements Adopted in 2020 — The following table provides a brief description of recent accounting pronouncements that had an impact on the Company’s 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 consolidated financial statements. New Accounting Standards Adopted ASU Number and Name Description Date of Adoption Effect on the financial statements upon adoption 2016-02, 2018-01, 2018-10, 2018-11, 2018-20, 2019-01, Leases (Topic 842) ASC 842 was adopted by sPower on January 1, 2020. sPower was not required to adopt ASC 842 using the public adoption date, as sPower is an equity method investee that meets the definition of a public business entity only by virtue of the inclusion of its summarized financial information in the Company’s SEC filings. January 1, 2020 The adoption of this standard resulted in a $4 million decrease to accumulated deficit attributable to the AES Corporation stockholders’ equity. 2016-13, 2018-19, 2019-04, 2019-05, 2019-10, 2019-11, 2020-02, 2020-03, Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments See discussion of the ASU below. January 1, 2020 See impact upon adoption of the standard below. ASC 326 — Financial Instruments — Credit Losses On January 1, 2020, the Company adopted ASC 326 Financial Instruments — Credit Losses and its subsequent corresponding updates (“ASC 326”). The new standard updates the impairment model for financial assets measured at amortized cost, known as the Current Expected Credit Loss (“CECL”) model. For trade and other receivables, held-to-maturity debt securities, loans, and other instruments, entities are required to use a new forward-looking "expected loss" model that generally results in the earlier recognition of an allowance for credit losses. For available-for-sale debt securities with unrealized losses, entities measure credit losses as it was done under previous GAAP, except that unrealized losses due to credit-related factors are now recognized as an allowance on the balance sheet with a corresponding adjustment to earnings in the income statement. The Company applied the modified retrospective method of adoption for ASC 326. Under this transition method, the Company applied the transition provisions starting at the date of adoption. The cumulative effect of the adoption of ASC 326 on our January 1, 2020 Condensed Consolidated Balance Sheet was as follows (in millions): Condensed Consolidated Balance Sheet Balance at December 31, 2019 Adjustments Due to ASC 326 Balance at January 1, 2020 Assets Accounts receivable, net of allowance for doubtful accounts of $20 $ 1,479 $ — $ 1,479 Other current assets (1) 802 (2 ) 800 Deferred income taxes 156 9 165 Loan receivable, net of allowance of $32 1,351 (32 ) 1,319 Other noncurrent assets (2) 1,635 (30 ) 1,605 Liabilities and Equity Accumulated deficit $ (692 ) $ (39 ) $ (731 ) Noncontrolling interests 2,233 (16 ) 2,217 _________________________ (1) Other current assets include the short-term portion of the Mong Duong loan receivable. (2) Other noncurrent assets include Argentina financing receivables. Mong Duong — The Mong Duong II power plant in Vietnam is the primary driver of changes in credit reserves under the new standard. This plant is operated under a build, operate, and transfer (“BOT”) contract and will be transferred to the Vietnamese government after the completion of a 25-year PPA. A loan receivable was recognized in 2018 upon the adoption of ASC 606 in order to account for the future expected payments for the construction performance obligation portion of the BOT contract. As the payments for the construction performance obligation occur over a 25-year term, a significant financing element was determined to exist which is accounted for under the effective interest rate method. Historically, the Company has not incurred any losses on this arrangement, of which no directly comparable assets exist in the market. In order to determine expected credit losses under ASC 326 arising from this $1.4 billion loan receivable as of January 1, 2020, the Company considered average historical default and recovery rates on similarly rated sovereign bonds, which formed an initial basis for developing a probability of default, net of expected recoveries, to be applied as a key credit quality indicator for this arrangement. A resulting estimated loss rate of 2.4% was applied to the weighted-average remaining life of the loan receivable, after adjustments for certain asset-specific characteristics, including the Company’s status as a large foreign direct investor in Vietnam, Mong Duong’s status as critical energy infrastructure in Vietnam, and cash flows from the operations of the plant, which are under the Company’s control until the end of the BOT contract. As a result of this analysis, the Company recognized an opening CECL reserve of $34 million as an adjustment to Accumulated deficit and Noncontrolling interests as of January 1, 2020. Argentina — Exposure to CAMMESA, the administrator of the wholesale energy market in Argentina, is the driver of credit reserves in Argentina. As discussed in Note 7 of the Company’s 2019 Form 10-K, the Company has credit exposures through the FONINVEMEM Agreements, other agreements related to resolutions passed by the Argentine government in which AES Argentina will receive compensation for investments in new generation plants and technologies, as well as regular accounts receivable balances. The timing of collections depends on corresponding agreements and collectability of these receivables are assessed on an ongoing basis. Collection of the principal and interest on these receivables is subject to various business risks and uncertainties, including, but not limited to, the continued operation of power plants which generate cash for payments of these receivables, regulatory changes that could impact the timing and amount of collections, and economic conditions in Argentina. The Company monitors these risks, including the credit ratings of the Argentine government, on a quarterly basis to assess the collectability of these receivables. Historically, the Company has not incurred any credit-related losses on these receivables. In order to determine expected credit losses under ASC 326, the Company considered historical default probabilities utilizing similarly rated sovereign bonds and historic recovery rates for Argentine government bond defaults. This information formed an initial basis for developing a probability of default, net of expected recoveries, to be applied as a key credit quality indicator across the underlying financing receivables. A resulting estimated weighted average loss rate of 41.2% was applied to the remaining balance of these receivables, after adjustments for certain asset-specific characteristics, including AES Argentina’s role in providing critical energy infrastructure to Argentina, our history of collections on these receivables, and the average term that the receivables are expected to be outstanding. As a result of this analysis, the Company recognized an opening CECL reserve of $29 million as an adjustment to Accumulated deficit as of January 1, 2020. Other financial assets — Application of ASC 326 to the Company’s $1.5 billion of trade accounts receivable and $326 million of available-for-sale debt securities at January 1, 2020 did not result in any material adjustments, primarily due to the short-term duration and high turnover of these financial assets. Additionally, a large portion of our trade accounts receivables and amounts reserved for doubtful accounts under legacy GAAP arise from arrangements accounted for as an operating lease under ASC 842, which are excluded from the scope of ASC 326. As discussed in Note 7 of the Company’s 2019 Form 10-K, AES Gener recorded $33 million of noncurrent receivables pertaining to revenues recognized on regulated energy contracts that were impacted by the Stabilization Fund created by the Chilean government in October 2019. It is expected that these noncurrent receivables will be collected prior to December 31, 2027. However, given the investment grade rating of Chile and the history of zero credit losses for regulated customers, management determined that no incremental CECL reserves were required to be recognized as of January 1, 2020. The following table represents the rollforward of the allowance for credit losses from January 1, 2020 to June 30, 2020 (in millions): Rollforward of CECL Reserves by Portfolio Segment Reserve at January 1, 2020 Current Period Provision Write-offs charged against allowance Recoveries Collected Foreign Exchange Reserve at June 30, 2020 Accounts Receivable (1) $ 4 $ 10 $ (7 ) $ 5 $ — $ 12 Mong Duong Loan Receivable 34 — — (1 ) — 33 Argentina Receivables 29 2 — (1 ) (4 ) 26 Other 1 — — — — 1 Total CECL Reserves $ 68 $ 12 $ (7 ) $ 3 $ (4 ) $ 72 _____________________________ (1) Excludes operating lease receivable allowances and contractual dispute allowances of $16 million and $6 million as of January 1 , 2020 and June 30, 2020 , respectively. Those reserves are not in scope under ASC 326.

Segment Reporting	The segment reporting structure uses the Company’s management reporting structure as its foundation to reflect how the Company manages the businesses internally and is mainly organized by geographic regions, which provides a socio-political-economic understanding of our business. The management reporting structure is organized by four SBUs led by our President and Chief Executive Officer: US and Utilities, South America, MCAC, and Eurasia SBUs. 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. Corporate and Other — Included in “Corporate and Other” are the results of the AES self-insurance company and certain equity affiliates, 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 PTC as its primary segment performance measure. Adjusted PTC, a non-GAAP measure, is defined by the Company as pre-tax income from continuing operations attributable to The AES Corporation excluding gains or losses of the consolidated entity 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) costs directly associated with a major restructuring program, including, but not limited to, workforce reduction efforts, relocations, and office consolidation. Adjusted PTC also includes net equity in earnings of affiliates on an after-tax basis adjusted for the same gains or losses excluded from consolidated entities. The Company has concluded that Adjusted PTC 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 complexity, the Company concluded that Adjusted PTC 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 PTC are presented before inter-segment eliminations, which includes the effect of intercompany transactions with other segments except for interest, 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.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Accounting Standards Update and Change in Accounting Principle [Table Text Block]	New Accounting Pronouncements Adopted in 2020 — The following table provides a brief description of recent accounting pronouncements that had an impact on the Company’s 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 consolidated financial statements. New Accounting Standards Adopted ASU Number and Name Description Date of Adoption Effect on the financial statements upon adoption 2016-02, 2018-01, 2018-10, 2018-11, 2018-20, 2019-01, Leases (Topic 842) ASC 842 was adopted by sPower on January 1, 2020. sPower was not required to adopt ASC 842 using the public adoption date, as sPower is an equity method investee that meets the definition of a public business entity only by virtue of the inclusion of its summarized financial information in the Company’s SEC filings. January 1, 2020 The adoption of this standard resulted in a $4 million decrease to accumulated deficit attributable to the AES Corporation stockholders’ equity. 2016-13, 2018-19, 2019-04, 2019-05, 2019-10, 2019-11, 2020-02, 2020-03, Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments See discussion of the ASU below. January 1, 2020 See impact upon adoption of the standard below. ASC 326 — Financial Instruments — Credit Losses On January 1, 2020, the Company adopted ASC 326 Financial Instruments — Credit Losses and its subsequent corresponding updates (“ASC 326”). The new standard updates the impairment model for financial assets measured at amortized cost, known as the Current Expected Credit Loss (“CECL”) model. For trade and other receivables, held-to-maturity debt securities, loans, and other instruments, entities are required to use a new forward-looking "expected loss" model that generally results in the earlier recognition of an allowance for credit losses. For available-for-sale debt securities with unrealized losses, entities measure credit losses as it was done under previous GAAP, except that unrealized losses due to credit-related factors are now recognized as an allowance on the balance sheet with a corresponding adjustment to earnings in the income statement. The Company applied the modified retrospective method of adoption for ASC 326. Under this transition method, the Company applied the transition provisions starting at the date of adoption. The cumulative effect of the adoption of ASC 326 on our January 1, 2020 Condensed Consolidated Balance Sheet was as follows (in millions): Condensed Consolidated Balance Sheet Balance at December 31, 2019 Adjustments Due to ASC 326 Balance at January 1, 2020 Assets Accounts receivable, net of allowance for doubtful accounts of $20 $ 1,479 $ — $ 1,479 Other current assets (1) 802 (2 ) 800 Deferred income taxes 156 9 165 Loan receivable, net of allowance of $32 1,351 (32 ) 1,319 Other noncurrent assets (2) 1,635 (30 ) 1,605 Liabilities and Equity Accumulated deficit $ (692 ) $ (39 ) $ (731 ) Noncontrolling interests 2,233 (16 ) 2,217 _________________________ (1) Other current assets include the short-term portion of the Mong Duong loan receivable. (2) Other noncurrent assets include Argentina financing receivables. Mong Duong — The Mong Duong II power plant in Vietnam is the primary driver of changes in credit reserves under the new standard. This plant is operated under a build, operate, and transfer (“BOT”) contract and will be transferred to the Vietnamese government after the completion of a 25-year PPA. A loan receivable was recognized in 2018 upon the adoption of ASC 606 in order to account for the future expected payments for the construction performance obligation portion of the BOT contract. As the payments for the construction performance obligation occur over a 25-year term, a significant financing element was determined to exist which is accounted for under the effective interest rate method. Historically, the Company has not incurred any losses on this arrangement, of which no directly comparable assets exist in the market. In order to determine expected credit losses under ASC 326 arising from this $1.4 billion loan receivable as of January 1, 2020, the Company considered average historical default and recovery rates on similarly rated sovereign bonds, which formed an initial basis for developing a probability of default, net of expected recoveries, to be applied as a key credit quality indicator for this arrangement. A resulting estimated loss rate of 2.4% was applied to the weighted-average remaining life of the loan receivable, after adjustments for certain asset-specific characteristics, including the Company’s status as a large foreign direct investor in Vietnam, Mong Duong’s status as critical energy infrastructure in Vietnam, and cash flows from the operations of the plant, which are under the Company’s control until the end of the BOT contract. As a result of this analysis, the Company recognized an opening CECL reserve of $34 million as an adjustment to Accumulated deficit and Noncontrolling interests as of January 1, 2020. Argentina — Exposure to CAMMESA, the administrator of the wholesale energy market in Argentina, is the driver of credit reserves in Argentina. As discussed in Note 7 of the Company’s 2019 Form 10-K, the Company has credit exposures through the FONINVEMEM Agreements, other agreements related to resolutions passed by the Argentine government in which AES Argentina will receive compensation for investments in new generation plants and technologies, as well as regular accounts receivable balances. The timing of collections depends on corresponding agreements and collectability of these receivables are assessed on an ongoing basis. Collection of the principal and interest on these receivables is subject to various business risks and uncertainties, including, but not limited to, the continued operation of power plants which generate cash for payments of these receivables, regulatory changes that could impact the timing and amount of collections, and economic conditions in Argentina. The Company monitors these risks, including the credit ratings of the Argentine government, on a quarterly basis to assess the collectability of these receivables. Historically, the Company has not incurred any credit-related losses on these receivables. In order to determine expected credit losses under ASC 326, the Company considered historical default probabilities utilizing similarly rated sovereign bonds and historic recovery rates for Argentine government bond defaults. This information formed an initial basis for developing a probability of default, net of expected recoveries, to be applied as a key credit quality indicator across the underlying financing receivables. A resulting estimated weighted average loss rate of 41.2% was applied to the remaining balance of these receivables, after adjustments for certain asset-specific characteristics, including AES Argentina’s role in providing critical energy infrastructure to Argentina, our history of collections on these receivables, and the average term that the receivables are expected to be outstanding. As a result of this analysis, the Company recognized an opening CECL reserve of $29 million as an adjustment to Accumulated deficit as of January 1, 2020. Other financial assets — Application of ASC 326 to the Company’s $1.5 billion of trade accounts receivable and $326 million of available-for-sale debt securities at January 1, 2020 did not result in any material adjustments, primarily due to the short-term duration and high turnover of these financial assets. Additionally, a large portion of our trade accounts receivables and amounts reserved for doubtful accounts under legacy GAAP arise from arrangements accounted for as an operating lease under ASC 842, which are excluded from the scope of ASC 326. As discussed in Note 7 of the Company’s 2019 Form 10-K, AES Gener recorded $33 million of noncurrent receivables pertaining to revenues recognized on regulated energy contracts that were impacted by the Stabilization Fund created by the Chilean government in October 2019. It is expected that these noncurrent receivables will be collected prior to December 31, 2027. However, given the investment grade rating of Chile and the history of zero credit losses for regulated customers, management determined that no incremental CECL reserves were required to be recognized as of January 1, 2020. The following table represents the rollforward of the allowance for credit losses from January 1, 2020 to June 30, 2020 (in millions): Rollforward of CECL Reserves by Portfolio Segment Reserve at January 1, 2020 Current Period Provision Write-offs charged against allowance Recoveries Collected Foreign Exchange Reserve at June 30, 2020 Accounts Receivable (1) $ 4 $ 10 $ (7 ) $ 5 $ — $ 12 Mong Duong Loan Receivable 34 — — (1 ) — 33 Argentina Receivables 29 2 — (1 ) (4 ) 26 Other 1 — — — — 1 Total CECL Reserves $ 68 $ 12 $ (7 ) $ 3 $ (4 ) $ 72 _____________________________ (1) Excludes operating lease receivable allowances and contractual dispute allowances of $16 million and $6 million as of January 1 , 2020 and June 30, 2020 , respectively. Those reserves are not in scope under ASC 326.
