Subsequent Events [Text Block] | SUBSEQUENT EVENTS Kazakhstan Hydroelectric — On October 2, 2017, the Company transferred 100% of shares in Shulbinsk HPP and Ust-Kamenogorsk HPP to the Republic of Kazakhstan in accordance with the termination of the concession agreement. The Company expects to record a loss on disposal of at least $37 million in the fourth quarter of 2017. See Note 16—Held-for-Sale Businesses and Dispositions for further discussion. Eletropaulo — In September 2017, the majority of Eletropaulo’s shareholders approved the transfer of Eletropaulo’s shares to the Novo Mercado. However, shareholders holding approximately 3 million shares, representing 2.7% of the total preferred shares, have indicated their preference to exercise withdrawal rights, which allows them to redeem their shares and receive a cash payment at book value for tendering their shares to Eletropaulo. Eletropaulo has now received all third party approvals to migrate to the Novo Mercado. The migration will be submitted to the Eletropaulo Board for confirmation that the costs associated with the exercise of the withdrawal rights are not significant enough to prevent migration. Once confirmed and the preferred shares are converted into ordinary shares, AES will no longer control Eletropaulo. Losing control will result in deconsolidation of Eletropaulo and the recording of an equity method investment for the remaining interest held in Eletropaulo. As of September 30, 2017, Eletropaulo had cumulative translation losses attributable to AES of $452 million and pension losses attributable to AES in other comprehensive income of $243 million, both of which will be recognized in earnings if Eletropaulo is deconsolidated. See Note 15—Discontinued Operations for further discussion.
