Acquisitions Disclosures [Text Block] | Ventus Wind Complex — In December 2020, AES Brasil completed the acquisition of the Ventus Wind Complex ("Ventus") for $91 million, including $4 million of expected working capital adjustments. At closing, the Company made an initial cash payment of $44 million. The remainder was recorded as a note payable, which will be substantially satisfied via a second installment payment expected to occur in the second quarter of 2021. The transaction was accounted for as an asset acquisition; therefore, the total amount of consideration, plus transaction costs, was allocated to the individual assets and liabilities assumed based on their relative fair values. Any differences arising from post-closing adjustments will be allocated accordingly. Ventus is reported in the South America SBU reportable segment. Penonome I — In May 2020, AES Panama completed the acquisition of the Penonome I wind farm from Goldwind International for $80 million. The transaction was accounted for as an asset acquisition, therefore the consideration transferred, plus transaction costs, was allocated to the individual assets and liabilities assumed based on their relative fair values. Any differences arising from post-closing adjustments will be allocated accordingly. Penonome I is reported in the MCAC SBU reportable segment. Los Cururos — In November 2019, AES Gener completed the acquisition of the Los Cururos wind farm and transmission lines in Chile from EPM Chile S.A. for total consideration of $143 million, including $5 million in working capital adjustments paid in the first quarter of 2020. The transaction was accounted for as an asset acquisition, therefore the consideration transferred, plus transaction costs, was allocated to the individual assets acquired and liabilities assumed based on their relative fair values. Los Cururos is reported in the South America SBU reportable segment. Distributed Energy — In December 2018, Distributed Energy acquired the outstanding noncontrolling interest in a partnership holding various solar projects from its tax equity partner for $23 million of consideration in a non-cash transaction through the assumption of debt, increasing the Company's ownership to 100%. The partnership was previously classified as an equity method investment. The transaction was accounted for as an asset acquisition, therefore the Company remeasured the equity investment at fair value and recognized a loss of $5 million in Other expense in the Consolidated Statement of Operations. The fair value of the investment, along with the consideration transferred, plus transaction costs, was allocated to the individual assets acquired and liabilities assumed based on their relative fair values. Distributed Energy is reported in the US and Utilities SBU reportable segment. Oahu — In November 2018, AES Oahu amended a 2017 agreement to acquire 100% of Na Pua Makani Power Partners, a partnership designed to develop and hold a wind project in Hawaii. The fair value of the initial consideration was $53 million, of which $48 million was contingent on meeting predefined development milestones. The transaction was accounted for as an acquisition of a variable interest entity that did not meet the definition of a business, therefore the assets acquired and liabilities assumed were recorded at their fair values, which equaled the fair value of the consideration. As a result of the amendment, the Company paid $11 million in 2018 and the contingent consideration was reduced to $5 million, resulting in a $32 million gain on remeasurement of contingent consideration recorded in Other income in the Consolidated Statement of Operations. AES Oahu is reported in the US and Utilities SBU reportable segment. Guaimbê Solar Complex — In September 2018, AES Brasil completed the acquisition of the Guaimbê Solar Complex (“Guaimbê”) from Cobra do Brasil for $152 million, comprised of the exchange of $119 million of non-convertible debentures in project financing and additional cash consideration of $33 million. The transaction was accounted for as an asset acquisition, therefore the consideration transferred, plus transaction costs, was allocated to the individual assets acquired and liabilities assumed based on their relative fair values. Guaimbê is reported in the South America SBU reportable segment.
