Organization, Consolidation and Presentation of Financial Statements [Abstract]
FINANCIAL STATEMENT PRESENTATION	FINANCIAL STATEMENT PRESENTATION The prior-period condensed consolidated financial statements in this Quarterly Report on Form 10-Q (“Form 10-Q”) have been reclassified to reflect the businesses held-for-sale and discontinued operations as discussed in Note 15 —Discontinued Operations and Held-for-Sale Businesses . 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, variable interest entities (“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 and cash flows. The results of operations for the three and six months ended June 30, 2016 are not necessarily indicative of results that may be expected for the year ending December 31, 2016 . The accompanying condensed consolidated financial statements are unaudited and should be read in conjunction with the 2015 audited consolidated financial statements and notes thereto, which are included in the 2015 Form 10-K filed with the SEC on February 23, 2016 (the “ 2015 Form 10-K”). New Accounting Pronouncements — The following table provides a brief description of recent accounting pronouncements that had and/or could 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 2015-03, Interest — Imputation of Interest (Subtopic 835-30) The standard simplifies the presentation of debt issuance costs by requiring that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the standard. Transition method: retrospective. January 1, 2016 Deferred financing costs of $24 million previously classified within other current assets and $357 million previously classified within other noncurrent assets were reclassified to reduce the related debt liabilities as of December 31, 2015. 2015-15, Interest — Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements Given the absence of authoritative guidance within ASU 2015-03, this standard clarifies that the SEC Staff would not object to an entity presenting debt issuance costs related to line-of-credit arrangements as an asset that is subsequently amortized ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. Transition method: retrospective. January 1, 2016 Deferred financing costs related to lines-of-credit of $1 million recorded within other current assets and $23 million recorded within other noncurrent assets were not reclassified as of December 31, 2015. 2015-02, Consolidation — Amendments to the Consolidation Analysis (Topic 810) The standard makes targeted amendments to the current consolidation guidance and ends the deferral granted to investment companies from applying the VIE guidance. The standard amends the evaluation of whether (1) fees paid to a decision-maker or service providers represent a variable interest, (2) a limited partnership or similar entity has the characteristics of a VIE and (3) a reporting entity is the primary beneficiary of a VIE. Transition method: retrospective. January 1, 2016 None, other than that some entities previously consolidated under the voting model are now consolidated under the VIE model. New Accounting Standards Issued But Not Yet Effective ASU Number and Name Description Date of Adoption Effect on the financial statements upon adoption 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments The standard updates the impairment model for financial assets measured at amortized cost to an expected loss model rather than an incurred loss model. It also allows for the presentation of credit losses on available-for-sale debt securities as an allowance rather than a write down. Transition method: various. January 1, 2020 Early adoption is permitted only as of January 1, 2019. The Company is currently evaluating the impact of adopting the standard on its consolidated financial statements. 2016-09, Compensation — Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting The standard simplifies the following aspects of accounting for share-based payments awards: accounting for income taxes, classification of excess tax benefits on the statement of cash flows, forfeitures, statutory tax withholding requirements, classification of awards as either equity or liabilities and classification of employee taxes paid on statement of cash flows when an employer withholds shares for tax-withholding purposes. Transition method: various. January 1, 2017. Early adoption is permitted. The Company is currently evaluating the impact of adopting the standard on its consolidated financial statements. 2016-06, Derivatives and Hedging (Topic 815) — Contingent Put and Call Options in Debt Instruments This standard clarifies the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts. When a call (put) option is contingently exercisable, an entity will no longer assess whether the event that triggers the ability to exercise a call (put) option is related to interest rates or credit risks. Transition method: a modified retrospective basis to existing debt instruments as of the effective date. January 1, 2017. Early adoption is permitted. The Company is currently evaluating the impact of adopting the standard, but does not anticipate a material impact on its consolidated financial statements. 2016-05, Derivatives and Hedging (Topic 815) — Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships The standard clarifies that a change in the counterparty to a derivative instrument that has been designated as the hedging instrument does not require de-designation of that hedging relationship provided that all other hedge accounting criteria continue to be met. Transition method: prospective or a modified retrospective basis. January 1, 2017. Early adoption is permitted. The Company is currently evaluating the impact of adopting the standard, but does not anticipate a material impact on its consolidated financial statements. 2016-02, Leases (Topic 842) The standard creates Topic 842, Leases, which supersedes Topic 840, Leases. It introduces a lessee model that brings substantially all leases onto the balance sheet while retaining most of the principles of the existing lessor model in U.S. GAAP and aligning many of those principles with ASC 606, Revenue from Contracts with Customers. Transition method: modified retrospective approach with certain practical expedients. January 1, 2019. Early adoption is permitted. The Company is currently evaluating the impact of adopting the standard on its consolidated financial statements. 2016-01, Financial Instruments — Overall (Topic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities The standard significantly revises an entity’s accounting related to (1) the classification and measurement of investments in equity securities and (2) the presentation of certain fair value changes for financial liabilities measured at fair value. Also, it amends certain disclosure requirements associated with the fair value of financial instruments. Transition method: cumulative effect in Retained Earnings as of adoption or prospectively for equity investments without readily determinable fair value. January 1, 2018. Limited early adoption permitted. The Company is currently evaluating the impact of adopting the standard, but does not anticipate a material impact on its consolidated financial statements. 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory The standard replaces the current lower of cost or market test with a lower of cost or net realizable value test. Transition method: prospectively. January 1, 2017. Early adoption is permitted. The Company is currently evaluating the impact of adopting the standard on its consolidated financial statements. 2014-09, 2016-08, 2016-10, 2016-12 Revenue from Contracts with Customers (Topic 606), The Revenue from Contracts with Customers standard provides a single and comprehensive revenue recognition model for all contracts with customers to improve comparability. The standard contains principles to determine the measurement and timing of revenue recognition. The standard requires an entity to recognize revenue to depict the transfer of goods or services to customers at an amount that the entity expects to be entitled to in exchange for those goods or services. The amendments to the standard provide further clarification on contract revenue recognition specifically related to the implementation of the principal versus agent evaluation, the identification of performance obligations, clarification on accounting for licenses of intellectual property, and allows for the election to account for shipping and handling activities performed after control of a good has been transferred to the customer as a fulfillment cost. Transition method: a full retrospective or modified retrospective approach. January 1, 2018 (deferred by ASU No. 2015-14). Earlier application is permitted only as of January 1, 2017. The Company is currently evaluating the impact of adopting the standard on its consolidated financial statements.

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 value of the Company’s assets and liabilities has been determined using available market information. By virtue of these amounts being 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.

Debt Disclosure [Abstract]
DEBT	DEBT Recourse Debt In May 2016, the Company issued $500 million aggregate principal amount of 6.00% senior notes due 2026. The Company used these proceeds to redeem at par $495 million aggregate principal of its existing LIBOR + 3.00% senior unsecured notes due 2019. As a result of the latter transaction, the Company recognized a net loss on extinguishment of debt of $4 million for the three and six months ended June 30, 2016 that is included in the Condensed Consolidated Statement of Operations. In January 2016, the Company redeemed $125 million of its senior unsecured notes outstanding. The repayment included a portion of the 7.375% senior notes due in 2021, the 4.875% senior notes due in 2023, the 5.5% senior notes due in 2024, the 5.5% senior notes due in 2025 and the floating rate senior notes due in 2019. As a result of these transactions, the Company recognized a net gain on extinguishment of debt of $7 million for the six months ended June 30, 2016 that is included in the Condensed Consolidated Statement of Operations. In April 2015, the Company issued $575 million aggregate principal amount of 5.50% senior notes due 2025. Concurrent with this offering, the Company redeemed via tender offers $344 million aggregate principal of its existing 8.00% senior unsecured notes due 2017, and $156 million of its existing 8.00% senior unsecured notes due 2020. As a result of the latter transaction, the Company recognized a loss on extinguishment of debt of $82 million for the three and six months ended June 30, 2015 that is included in the Condensed Consolidated Statement of Operations. In March 2015, the Company redeemed in full the $151 million balance of its 7.75% senior unsecured notes due October 2015 and the $164 million balance of its 9.75% senior unsecured notes due April 2016. As a result of these transactions, the Company recognized a loss on extinguishment of debt of $23 million for the six months ended June 30, 2015 that is included in the Condensed Consolidated Statement of Operations. Non-Recourse Debt During the six months ended June 30, 2016 , the Company’s subsidiaries engaged in the following significant debt transactions: Subsidiary Issuances Repayments Gain (Loss) on Extinguishment of Debt IPALCO $ 573 $ (390 ) $ — Gener 575 (228 ) 7 Andres 220 (180 ) (2 ) Los Mina 118 — — Itabo Opco 100 (70 ) (1 ) Maritza 18 (106 ) — Other 171 (398 ) (3 ) $ 1,775 $ (1,372 ) $ 1 Non-recourse debt in default — The following table summarizes the Company’s subsidiary non-recourse debt in default as of June 30, 2016 (in millions). Due to the defaults, these amounts are included in the current portion of non-recourse debt: Subsidiary Primary Nature of Default Debt in Default Net Assets Kavarna (Bulgaria) Covenant $ 133 $ 46 Sogrinsk (Kazakhstan) Covenant 5 6 $ 138 The above defaults are not payment defaults. All of the subsidiary non-recourse debt defaults were triggered by failure to comply with covenants and/or other conditions such as (but not limited to) failure to meet information covenants, complete construction or other milestones in an allocated time, meet certain minimum or maximum financial ratios, or other requirements contained in the non-recourse debt documents of the applicable subsidiary. In the event that there is a default, bankruptcy or maturity acceleration at a subsidiary or group of subsidiaries that meets the applicable definition of materiality under the Parent Company’s corporate debt agreements, there could be a cross-default to the Company’s recourse debt. A material subsidiary is defined in the Parent Company’s senior secured credit facility as any business that contributed 20% or more of the Parent Company’s total cash distributions from businesses for the four most recently completed fiscal quarters. As of June 30, 2016 , none of the defaults listed above individually or in the aggregate result in or are 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 senior secured credit facility, restricted payments will be limited to regular quarterly shareholder dividends at the then-prevailing rate. Payment 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 financing, acquisition, power purchase 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 subsidiaries. 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 more than 18 years . Presented below is the Parent Company’s current undiscounted exposure to guarantees and the potential range of maximum undiscounted 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. The table below summarizes the Parent Company’s contingent contractual obligations as of June 30, 2016 (in millions, except range amounts). Contingent Contractual Obligations Amount No. of Agreements Maximum Exposure Range for Each Agreement Guarantees and commitments $ 416 15 <$1 — 53 Letters of credit under the unsecured credit facility 75 4 $2 — 29 Asset sale related indemnities (1) 27 1 $27 Cash collateralized letters of credit 2 1 $3 Letters of credit under the senior secured credit facility 7 18 <$1 — 1 Total $ 527 39 _____________________________ (1) Excludes normal and customary representations and warranties in agreements for the sale of assets (including ownership in associated legal entities) where the associated risk is considered to be nominal. During the six months ended June 30, 2016 , the Company paid letter of credit fees ranging from 0.2% to 2.5% 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. As of June 30, 2016 and December 31, 2015 , the Company had recognized liabilities of $10 million for both periods, relating to projected environmental remediation costs. Due to the uncertainties associated with environmental assessment and remediation activities, future costs of compliance or remediation with current legislation or costs for new legislation introduced 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, 2016 . In aggregate, the Company estimates the potential losses related to environmental matters, where estimable, to be up to $22 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 evaluated claims in accordance with the accounting guidance for contingencies that it deems both probable and reasonably estimable and, accordingly, has recognized aggregate liabilities for all claims of approximately $208 million and $179 million as of June 30, 2016 and December 31, 2015 , respectively. Recognized aggregate liabilities for these claims 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 labor and employment, non-income tax and customer disputes in international jurisdictions, principally Brazil where there are a number of labor and employment lawsuits. The complaints generally seek unspecified monetary damages, injunctive relief, or other relief. The AES subsidiaries have denied any liability and intend to vigorously defend themselves in all of these proceedings. 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. The Company believes, based upon information it currently possesses and taking into account established accruals for liabilities and its insurance coverage, that the ultimate outcome of these proceedings and actions is unlikely to have a material effect on the Company’s consolidated financial statements. However, 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, 2016 . The material contingencies where a loss is reasonably possible primarily include (1) claims under financing agreements, including the Eletrobrás case (see Part II—Item 1— Legal Proceedings of this Form 10-Q ); (2) disputes with offtakers, suppliers and EPC contractors; (3) alleged violation of monopoly laws and regulations; (4) income tax and non-income tax matters with tax authorities; and (5) regulatory matters. In aggregate, the Company estimates that the range of potential losses, where estimable, related to these reasonably possible material contingencies is between $1.4 billion and $1.7 billion . Certain claims are in settlement negotiations. These claims considered reasonably possible do not include the amounts accrued, as discussed in the preceding paragraph, nor do they include income tax-related contingencies which are considered part of our uncertain tax positions. Regulatory — During the fourth quarter of 2013, the Company recognized a regulatory liability of $269 million for a contingency related to an administrative ruling which required Eletropaulo to refund customers’ amounts due to the regulatory asset base. During the second half of 2014, Eletropaulo started refunding customers as part of the tariff. In January 2015, ANEEL updated the tariff to exclude any further customer refunds. On June 30, 2015, ANEEL included in the tariff reset the reimbursement to Eletropaulo of these amounts previously refunded to customers to begin in July 2015. During the second quarter of 2015, as a result of favorable events, management reassessed the contingency and determined that it no longer meets the recognition criteria under ASC 450 Contingencies . Management believes that it is now only reasonably possible that Eletropaulo will have to refund these amounts to customers. Accordingly, the Company reversed the remaining regulatory liability for this contingency of $161 million in the second quarter of 2015, which increased Regulated Revenue by $97 million and reduced Interest Expense by $64 million . Amounts related to this case are now included as part of our reasonably possible contingent range discussed in the preceding paragraph.

Equity Transactions with Noncontrolling Interests IPALCO — In March 2016, La Caisse de depot et placement du Quebec (“CDPQ”) completed its investment commitment in IPALCO by investing $134 million in IPALCO Enterprises, Inc. (“IPALCO”). As a result of this transaction, IPALCO is owned by AES U.S. Investments ( 82% ) and CDPQ ( 18% ), and AES U.S. Investments is owned by AES U.S. Holdings, LLC ( 85% ) and CDPQ ( 15% ). As a cumulative result of CDPQ’s investment transactions, the Company recognized an increase of $463 million to additional paid-in capital and a reduction to retained earnings of $463 million for the excess of the fair value of the shares over their book value. Additionally, $84 million in taxes and transaction costs were recognized as a net decrease to equity. Since the NCI is contingently redeemable, the total fair value of the consideration received of $594 million is classified in temporary equity as redeemable stock of subsidiaries on the Condensed Consolidated Balance Sheet as of June 30, 2016 . No gain or loss was recognized in net income as the sale is not considered to be a sale of in-substance real estate. Any subsequent adjustments to allocate earnings and dividends to CDPQ will be classified as NCI within permanent equity and adjustments to the amount in temporary equity will occur only if and when it is probable that the shares will become redeemable. As the Company maintained control after the sale, IPALCO continues to be accounted for as a consolidated subsidiary within the US SBU reportable segment. Jordan — On February 18, 2016, the Company completed the sale of 40% of its interest in a wholly owned subsidiary in Jordan which owns a controlling interest in the Jordan IPP4 gas-fired plant, for $21 million . The transaction was accounted for as a sale of in-substance real estate and a pretax gain of $4 million , net of transaction costs, was recognized in net income. The cash proceeds from the sale are reflected in Proceeds from the sale of businesses, net of cash sold on the Consolidated Statement of Cash Flows for the period ended June 30, 2016 . After completion of the sale, the Company has a 36% net ownership interest in Jordan IPP4 and will continue to manage and operate the plant, with 40% owned by Mitsui Ltd. and 24% owned by Nebras Power Q.S.C. As the Company maintained control after the sale, Jordan IPP4 continues to be consolidated by the Company within the Europe SBU reportable segment. Deconsolidations UK Wind — During the second quarter of 2016, the Company determined it no longer had control of its wind development projects in the United Kingdom (“UK Wind”) as the Company no longer held seats on the board of directors. In accordance with the accounting guidance, UK Wind was deconsolidated and a loss on deconsolidation of $20 million was recorded to Gain (loss) on disposal and sale of businesses in the Condensed Consolidated Statement of Operations to write off the Company’s non-controlling interest in the project. The UK Wind projects were reported in the Europe SBU reportable segment.

The cumulative repurchases from the commencement of the Program in July 2010 through June 30, 2016 totaled 154.3 million shares for a total cost of $1.9 billion , at an average price per share of $12.12 (including a nominal amount of commissions). As of June 30, 2016 , $264 million remained available for repurchase under the Program.

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 organized by geographic regions which provides a socio-political-economic understanding of our business. The management reporting structure is organized by six SBUs led by our President and Chief Executive Officer: US; Andes; Brazil; MCAC; Europe; and Asia SBUs. Using the accounting guidance on segment reporting, the Company determined that it has six reportable segments corresponding to its six SBUs. Corporate and Other — Corporate overhead costs which are not directly associated with the operations of our six reportable segments are included in “Corporate and Other.” Also included are 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 pretax income from continuing operations attributable to AES excluding (1) unrealized gains or losses related to derivative transactions, (2) unrealized foreign currency gains or losses, (3) gains or losses due to dispositions and acquisitions of business interests, (4) losses due to impairments, and (5) costs due to the early retirement of debt. The Company has concluded that Adjusted PTC best 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.

Uncertainty created by the Supreme Court of Ohio’s June 20, 2016 opinion, lower expectations of future revenue resulting from the most recent PJM capacity auction, and higher anticipated environmental compliance costs resulting from third party studies were collectively determined to be an impairment indicator for these assets. The Company performed a long-lived asset impairment analysis and determined that the carrying amount of Killen, a coal-fired generation facility, and certain DPL peaking generation facilities were not recoverable. The Killen and DPL peaking generation asset groups were determined to have a fair value of $84 million and $5 million , respectively, using the income approach. As a result, the Company recognized a total asset impairment expense of $235 million . DPL is reported in the US SBU reportable segment. Buffalo Gap II — During the first quarter of 2016, the Company tested the recoverability of its long-lived assets at Buffalo Gap II. Impairment indicators were identified based on a decline in forward power curves. The Company determined that the carrying amount was not recoverable. The Buffalo Gap II asset group was determined to have a fair value of 92 million using the income approach. As a result, the Company recognized an asset impairment expense of $159 million ( $49 million attributable to AES). Buffalo Gap II is reported in the US SBU reportable segment. UK Wind — During the second quarter of 2015, the Company decided to no longer pursue two wind projects in the United Kingdom based on recent regulatory clarifications specific to these projects, resulting in a full impairment. Impairment indicators were also identified at four other wind projects based on their development status and a reassessment of the likelihood that each project would be pursued given aviation concerns, regulatory changes, economic considerations and other factors. The Company determined that the carrying amounts of each of these asset groups, which totaled $38 million , were not recoverable. In aggregate, the asset groups were determined to have a fair value of $1 million using the market approach and, as a result, the Company recognized an asset impairment expense of $37 million . The UK Wind projects were reported in the Europe SBU reportable segment.

Income Tax Disclosure [Text Block]	INCOME TAXES Chilean Tax Reform — In February 2016, the Chilean government enacted further reforms to its income tax laws that resulted in an increase to statutory income tax rates for most of our Chilean businesses from 25% to 25.5% in 2017 and to 27% for 2018 and future years. The impact of remeasuring deferred taxes to account for the enacted change in future applicable income tax rates was recognized as discrete income tax expense in the first quarter of 2016, resulting in an increase of $26 million to consolidated income tax expense.

DISPOSITIONS AND HELD-FOR-SALE BUSINESSES	DISCONTINUED OPERATIONS AND HELD-FOR-SALE BUSINESSES Discontinued Operations Sul — In June 2016, the Company executed an agreement for the sale of its wholly-owned subsidiary AES Sul, a distribution business in Brazil. Upon meeting the held-for-sale criteria, the Company recognized an after tax loss of $382 million comprised of a pretax impairment charge of $783 million , offset by a tax benefit of $266 million related to the impairment of the Sul long lived assets and a tax benefit of $135 million for deferred taxes related to the investment in AES Sul. The carrying value of the AES Sul asset group of $1.6 billion was greater than its approximate fair value less costs to sell of $470 million . However, the impairment charge was limited to the carrying value of the long lived assets of the AES Sul disposal group as of June 30, 2016 . The sale is subject to regulatory approval and is expected to close in the second half of 2016. Upon disposal of AES Sul, we expect to incur an additional after tax loss on sale of approximately $700 million subject to factors such as adjustments to sales proceeds and potential future movements in exchange rates. The cumulative impact to earnings of the impairment and loss on sale is expected to be approximately $1.1 billion . This includes the reclassification of approximately $1 billion of cumulative translation losses, resulting in an expected net reduction to the Company’s stockholders’ equity of approximately $100 million . Due to a recent portfolio evaluation, we determined that AES Sul is no longer aligned with our strategic goals and its disposal is part of a strategic shift of the Company in the Brazil distribution sector. Therefore, we have reported the results of operations and financial position of Sul as discontinued operations in the consolidated financial statements for all periods presented. Sul’s pretax loss attributable to AES was $779 million and $792 million , respectively, for the three and six months ended June 30, 2016 , and $13 million and $24 million , respectively, for the three and six months ended June 30, 2015 . Prior to its classification as discontinued operations, Sul was reported in the Brazil SBU reportable segment. The following table summarizes the carrying amounts of the major classes of assets and liabilities of discontinued operations and held-for-sale businesses at June 30, 2016 and December 31, 2015 : (in millions) June 30, 2016 December 31, 2015 Assets of discontinued operations and held-for-sale businesses: Cash and cash equivalents $ 5 $ 5 Short-term investments 78 15 Accounts receivable, net of allowance for doubtful accounts of $18 and $8 respectively 183 171 Property, plant and equipment and intangibles, net 837 668 Deferred income taxes 594 133 Other classes of assets that are not major 188 218 Loss recognized on classification as held-for-sale (3) (837 ) — Total assets of discontinued operations $ 1,048 $ 1,210 Other assets of businesses classified as held-for-sale (2) — 96 Total assets of discontinued operations and held-for-sale businesses (1) $ 1,048 $ 1,306 Liabilities of discontinued operations and held-for-sale businesses: Accounts payable $ 133 $ 150 Accrued interest 20 15 Accrued and other liabilities 151 150 Non-recourse debt 373 346 Other classes of liabilities that are not major 164 110 Total liabilities of discontinued operations $ 841 $ 771 Other liabilities of businesses classified as held-for-sale (2) — 13 Total liabilities of discontinued operations and held-for-sale businesses (1) $ 841 $ 784 _____________________________ (1) Amounts at December 31, 2015 are classified as both current and long-term on the Condensed Consolidated Balance Sheet.

The sale transaction closed on January 30, 2014 and net proceeds of $27 million were received. These wind projects were previously reported in the US SBU reportable segment. Under the terms of the sale agreement, the buyer was provided an option to purchase the Company's 100% interest in Armenia Mountain, a wind project in Pennsylvania, at a fixed price of $75 million . Approximately $3 million of the $27 million net proceeds was deferred and allocated to this option. The buyer exercised the option on March 31, 2015 and the sale was completed on July 1, 2015. Accordingly, Armenia Mountain was classified as held-for-sale as of June 30, 2015, but did not meet the criteria to be reported as a discontinued operation. Armenia Mountain’s results were therefore reflected within continuing operations in the Condensed Consolidated Statements of Operations. Armenia Mountain’s pretax income attributable to AES was $2 million and $6 million , respectively, for the three and six months ended June 30, 2015. Armenia Mountain was reported in the US SBU reportable segment. DISPOSITIONS DPLER — On January 1, 2016, the Company completed the sale of its interest in DPLER, a competitive retail marketer selling electricity to customers in Ohio. Upon completion, proceeds of $76 million were received and a gain on sale of $49 million was recognized. The sale of DPLER did not meet the criteria to be reported as a discontinued operation. Prior to its sale, DPLER was reported in the US SBU reportable segment. Kelanitissa — On January 27, 2016, the Company completed the sale of its interest in Kelanitissa, a diesel-fired generation station in Sri Lanka. Upon completion, proceeds of $18 million were received and a loss on sale of $5 million was recognized. The sale of Kelanitissa did not meet the criteria to be reported as a discontinued operation. Prior to its sale, Kelanitissa was reported in the Asia SBU reportable segment. UK Wind — During the second quarter of 2016, the Company deconsolidated UK Wind and recorded a loss on deconsolidation of $20 million to Gain (loss) on disposal and sale of businesses in the Condensed Consolidated Statement of Operations. Prior to deconsolidation, UK Wind was reported in the Europe SBU reportable segment. See Note 10 — Equity for additional information.

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 convertible securities. The effect of such potential common stock is computed using the treasury stock method or the if-converted method, as applicable. Presented below is a reconciliation, for the periods indicated, of the numerator and denominator of the basic and diluted earnings per share computation for income from continuing operations, where income represents the numerator and weighted average shares represents the denominator: (in millions, except per share data) 2016 2015 Three Months Ended June 30, Income Shares $ per Share Income Shares $ per Share BASIC EARNINGS PER SHARE Income (loss) from continuing operations attributable to The AES Corporation common stockholders $ (103 ) 659 $ (0.16 ) $ 79 693 $ 0.11 EFFECT OF DILUTIVE SECURITIES Restricted stock units — — — — 2 — DILUTED EARNINGS PER SHARE $ (103 ) 659 $ (0.16 ) $ 79 695 $ 0.11 Six Months Ended June 30, BASIC EARNINGS PER SHARE Income from continuing operations attributable to The AES Corporation common stockholders $ 32 660 $ 0.05 $ 228 698 $ 0.33 EFFECT OF DILUTIVE SECURITIES Stock options — — — — 1 — Restricted stock units — 2 — — 2 — DILUTED EARNINGS PER SHARE $ 32 662 $ 0.05 $ 228 701 $ 0.33 For the three and six months ended June 30, 2016 and 2015 , respectively, the calculation of diluted earnings per share excluded 8 million and 6 million outstanding stock awards which could potentially dilute basic earnings per share in the future. Additionally, for the three and six months ended June 30, 2016 and 2015 , all 15 million shares of potential common stock associated with convertible debentures were omitted from the earnings per share calculation as the impact would have been anti-dilutive. For the three months ended June 30, 2016 , the calculation of diluted earnings per share also excluded 5 million outstanding restricted stock units, that could potentially dilute earnings per share in the future. These restricted units were not included in the computation of diluted earnings per share for three months ended June 30, 2016 , because their impact would be anti-dilutive given the loss from continuing operations. Had the Company generated income from continuing operations in three months ended June 30, 2016 , 3 million potential shares of common stock related to the restricted stock units would have been included in diluted average shares outstanding.

Upon meeting the held-for-sale criteria, the Company recognized an after tax loss of $382 million comprised of a pretax impairment charge of $783 million , offset by a tax benefit of $266 million related to the impairment of the Sul long lived assets and a tax benefit of $135 million for deferred taxes related to the investment in AES Sul. The carrying value of the AES Sul asset group of $1.6 billion was greater than its approximate fair value less costs to sell of $470 million . However, the impairment charge was limited to the carrying value of the long lived assets of the AES Sul disposal group as of June 30, 2016 . The sale is subject to regulatory approval and is expected to close in the second half of 2016. Upon disposal of AES Sul, we expect to incur an additional after tax loss on sale of approximately $700 million subject to factors such as adjustments to sales proceeds and potential future movements in exchange rates. The cumulative impact to earnings of the impairment and loss on sale is expected to be approximately $1.1 billion . This includes the reclassification of approximately $1 billion of cumulative translation losses, resulting in an expected net reduction to the Company’s stockholders’ equity of approximately $100 million . Due to a recent portfolio evaluation, we determined that AES Sul is no longer aligned with our strategic goals and its disposal is part of a strategic shift of the Company in the Brazil distribution sector. Therefore, we have reported the results of operations and financial position of Sul as discontinued operations in the consolidated financial statements for all periods presented. Sul’s pretax loss attributable to AES was $779 million and $792 million , respectively, for the three and six months ended June 30, 2016 , and $13 million and $24 million , respectively, for the three and six months ended June 30, 2015 . Prior to its classification as discontinued operations, Sul was reported in the Brazil SBU reportable segment. The following table summarizes the carrying amounts of the major classes of assets and liabilities of discontinued operations and held-for-sale businesses at June 30, 2016 and December 31, 2015 : (in millions) June 30, 2016 December 31, 2015 Assets of discontinued operations and held-for-sale businesses: Cash and cash equivalents $ 5 $ 5 Short-term investments 78 15 Accounts receivable, net of allowance for doubtful accounts of $18 and $8 respectively 183 171 Property, plant and equipment and intangibles, net 837 668 Deferred income taxes 594 133 Other classes of assets that are not major 188 218 Loss recognized on classification as held-for-sale (3) (837 ) — Total assets of discontinued operations $ 1,048 $ 1,210 Other assets of businesses classified as held-for-sale (2) — 96 Total assets of discontinued operations and held-for-sale businesses (1) $ 1,048 $ 1,306 Liabilities of discontinued operations and held-for-sale businesses: Accounts payable $ 133 $ 150 Accrued interest 20 15 Accrued and other liabilities 151 150 Non-recourse debt 373 346 Other classes of liabilities that are not major 164 110 Total liabilities of discontinued operations $ 841 $ 771 Other liabilities of businesses classified as held-for-sale (2) — 13 Total liabilities of discontinued operations and held-for-sale businesses (1) $ 841 $ 784 _____________________________ (1) Amounts at December 31, 2015 are classified as both current and long-term on the Condensed Consolidated Balance Sheet. (2) DPLER and Kelanitissa classified as held-for-sale at December 31, 2015 . See Note 16 —Dispositions for further information. (3) Pre-tax impairment expense of $783 million is net of the impact from cumulative translation adjustments. The following table summarizes the carrying amounts of the major line items constituting losses from discontinued operations for the three and six months ended June 30, 2016 and 2015 : (in millions) Three Months Ended June 30, Six Months Ended June 30, Loss from discontinued operations, net of tax: 2016 2015 2016 2015 Revenue - regulated $ 219 $ 202 $ 419 $ 428 Cost of sales (204 ) (203 ) (408 ) (428 ) Asset impairment expense (783 ) — (783 ) — Other income and expense items that are not major (11 ) (12 ) (20 ) (24 ) Pretax loss from discontinued operations (779 ) (13 ) (792 ) (24 ) Income tax benefit 400 3 404 7 Loss from discontinued operations, net of tax $ (379 ) $ (10 ) $ (388 ) $ (17 ) The following table summarizes the operating and investing cash flows from discontinued operations for the six months ended June 30, 2016 and 2015 : Six Months Ended June 30, (in millions) 2016 2015 Cash flows from operating activities of discontinued operations $ 57 $ (47 ) Cash flows from investing activities of discontinued operations (84 ) 7 Held-For-Sale Businesses U.S. wind projects — In November 2013, the Company executed an agreement for the sale of its 100% membership interests in three wind projects: Condon in California, Lake Benton I in Minnesota and Storm Lake II in Iowa. The sale transaction closed on January 30, 2014 and net proceeds of $27 million were received. These wind projects were previously reported in the US SBU reportable segment. Under the terms of the sale agreement, the buyer was provided an option to purchase the Company's 100% interest in Armenia Mountain, a wind project in Pennsylvania, at a fixed price of $75 million . Approximately $3 million of the $27 million net proceeds was deferred and allocated to this option. The buyer exercised the option on March 31, 2015 and the sale was completed on July 1, 2015. Accordingly, Armenia Mountain was classified as held-for-sale as of June 30, 2015, but did not meet the criteria to be reported as a discontinued operation. Armenia Mountain’s results were therefore reflected within continuing operations in the Condensed Consolidated Statements of Operations. Armenia Mountain’s pretax income attributable to AES was $2 million and $6 million , respectively, for the three and six months ended June 30, 2015. Armenia Mountain was reported in the US SBU reportable segment. DISPOSITIONS DPLER — On January 1, 2016, the Company completed the sale of its interest in DPLER, a competitive retail marketer selling electricity to customers in Ohio. Upon completion, proceeds of $76 million were received and a gain on sale of $49 million was recognized. The sale of DPLER did not meet the criteria to be reported as a discontinued operation. Prior to its sale, DPLER was reported in the US SBU reportable segment. Kelanitissa — On January 27, 2016, the Company completed the sale of its interest in Kelanitissa, a diesel-fired generation station in Sri Lanka. Upon completion, proceeds of $18 million were received and a loss on sale of $5 million was recognized. The sale of Kelanitissa did not meet the criteria to be reported as a discontinued operation. Prior to its sale, Kelanitissa was reported in the Asia SBU reportable segment. UK Wind — During the second quarter of 2016, the Company deconsolidated UK Wind and recorded a loss on deconsolidation of $20 million to Gain (loss) on disposal and sale of businesses in the Condensed Consolidated Statement of Operations. Prior to deconsolidation, UK Wind was reported in the Europe SBU reportable segment. See Note 10 — Equity for additional information.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
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, variable interest entities (“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.
New Accounting Pronouncements Adopted	New Accounting Pronouncements — The following table provides a brief description of recent accounting pronouncements that had and/or could 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 2015-03, Interest — Imputation of Interest (Subtopic 835-30) The standard simplifies the presentation of debt issuance costs by requiring that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the standard. Transition method: retrospective. January 1, 2016 Deferred financing costs of $24 million previously classified within other current assets and $357 million previously classified within other noncurrent assets were reclassified to reduce the related debt liabilities as of December 31, 2015. 2015-15, Interest — Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements Given the absence of authoritative guidance within ASU 2015-03, this standard clarifies that the SEC Staff would not object to an entity presenting debt issuance costs related to line-of-credit arrangements as an asset that is subsequently amortized ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. Transition method: retrospective. January 1, 2016 Deferred financing costs related to lines-of-credit of $1 million recorded within other current assets and $23 million recorded within other noncurrent assets were not reclassified as of December 31, 2015. 2015-02, Consolidation — Amendments to the Consolidation Analysis (Topic 810) The standard makes targeted amendments to the current consolidation guidance and ends the deferral granted to investment companies from applying the VIE guidance. The standard amends the evaluation of whether (1) fees paid to a decision-maker or service providers represent a variable interest, (2) a limited partnership or similar entity has the characteristics of a VIE and (3) a reporting entity is the primary beneficiary of a VIE. Transition method: retrospective. January 1, 2016 None, other than that some entities previously consolidated under the voting model are now consolidated under the VIE model. New Accounting Standards Issued But Not Yet Effective ASU Number and Name Description Date of Adoption Effect on the financial statements upon adoption 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments The standard updates the impairment model for financial assets measured at amortized cost to an expected loss model rather than an incurred loss model. It also allows for the presentation of credit losses on available-for-sale debt securities as an allowance rather than a write down. Transition method: various. January 1, 2020 Early adoption is permitted only as of January 1, 2019. The Company is currently evaluating the impact of adopting the standard on its consolidated financial statements. 2016-09, Compensation — Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting The standard simplifies the following aspects of accounting for share-based payments awards: accounting for income taxes, classification of excess tax benefits on the statement of cash flows, forfeitures, statutory tax withholding requirements, classification of awards as either equity or liabilities and classification of employee taxes paid on statement of cash flows when an employer withholds shares for tax-withholding purposes. Transition method: various. January 1, 2017. Early adoption is permitted. The Company is currently evaluating the impact of adopting the standard on its consolidated financial statements. 2016-06, Derivatives and Hedging (Topic 815) — Contingent Put and Call Options in Debt Instruments This standard clarifies the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts. When a call (put) option is contingently exercisable, an entity will no longer assess whether the event that triggers the ability to exercise a call (put) option is related to interest rates or credit risks. Transition method: a modified retrospective basis to existing debt instruments as of the effective date. January 1, 2017. Early adoption is permitted. The Company is currently evaluating the impact of adopting the standard, but does not anticipate a material impact on its consolidated financial statements. 2016-05, Derivatives and Hedging (Topic 815) — Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships The standard clarifies that a change in the counterparty to a derivative instrument that has been designated as the hedging instrument does not require de-designation of that hedging relationship provided that all other hedge accounting criteria continue to be met. Transition method: prospective or a modified retrospective basis. January 1, 2017. Early adoption is permitted. The Company is currently evaluating the impact of adopting the standard, but does not anticipate a material impact on its consolidated financial statements. 2016-02, Leases (Topic 842) The standard creates Topic 842, Leases, which supersedes Topic 840, Leases. It introduces a lessee model that brings substantially all leases onto the balance sheet while retaining most of the principles of the existing lessor model in U.S. GAAP and aligning many of those principles with ASC 606, Revenue from Contracts with Customers. Transition method: modified retrospective approach with certain practical expedients. January 1, 2019. Early adoption is permitted. The Company is currently evaluating the impact of adopting the standard on its consolidated financial statements. 2016-01, Financial Instruments — Overall (Topic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities The standard significantly revises an entity’s accounting related to (1) the classification and measurement of investments in equity securities and (2) the presentation of certain fair value changes for financial liabilities measured at fair value. Also, it amends certain disclosure requirements associated with the fair value of financial instruments. Transition method: cumulative effect in Retained Earnings as of adoption or prospectively for equity investments without readily determinable fair value. January 1, 2018. Limited early adoption permitted. The Company is currently evaluating the impact of adopting the standard, but does not anticipate a material impact on its consolidated financial statements. 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory The standard replaces the current lower of cost or market test with a lower of cost or net realizable value test. Transition method: prospectively. January 1, 2017. Early adoption is permitted. The Company is currently evaluating the impact of adopting the standard on its consolidated financial statements. 2014-09, 2016-08, 2016-10, 2016-12 Revenue from Contracts with Customers (Topic 606), The Revenue from Contracts with Customers standard provides a single and comprehensive revenue recognition model for all contracts with customers to improve comparability. The standard contains principles to determine the measurement and timing of revenue recognition. The standard requires an entity to recognize revenue to depict the transfer of goods or services to customers at an amount that the entity expects to be entitled to in exchange for those goods or services. The amendments to the standard provide further clarification on contract revenue recognition specifically related to the implementation of the principal versus agent evaluation, the identification of performance obligations, clarification on accounting for licenses of intellectual property, and allows for the election to account for shipping and handling activities performed after control of a good has been transferred to the customer as a fulfillment cost. Transition method: a full retrospective or modified retrospective approach. January 1, 2018 (deferred by ASU No. 2015-14). Earlier application is permitted only as of January 1, 2017. The Company is currently evaluating the impact of adopting the standard on its consolidated financial statements.
Commitments and Contingencies	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.
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 organized by geographic regions which provides a socio-political-economic understanding of our business. The management reporting structure is organized by six SBUs led by our President and Chief Executive Officer: US; Andes; Brazil; MCAC; Europe; and Asia SBUs. Using the accounting guidance on segment reporting, the Company determined that it has six reportable segments corresponding to its six SBUs. Corporate and Other — Corporate overhead costs which are not directly associated with the operations of our six reportable segments are included in “Corporate and Other.” Also included are 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 pretax income from continuing operations attributable to AES excluding (1) unrealized gains or losses related to derivative transactions, (2) unrealized foreign currency gains or losses, (3) gains or losses due to dispositions and acquisitions of business interests, (4) losses due to impairments, and (5) costs due to the early retirement of debt. The Company has concluded that Adjusted PTC best 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.
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 convertible securities. The effect of such potential common stock is computed using the treasury stock method or the if-converted method, as applicable.
