Acquisitions And Divestitures | D. Acquisitions and Divestitures – In June 2012, Alcoa reached an agreement to sell its 351-megawatt Tapoco Hydroelectric Project (Tapoco) to Brookfield Renewable Energy Partners for $600 in cash, subject to certain post-closing adjustments. Tapoco is a four-station hydroelectric project located on the Little Tennessee and Cheoah Rivers in eastern Tennessee and western North Carolina. The transaction, which is subject to customary federal and state regulatory approvals, will include four generating stations and dams, 86 miles of transmission line, and approximately 14,500 acres of land associated with and surrounding Tapoco. The power generated by Tapoco was primarily consumed by Alcoa’s smelter in Tennessee, which was temporarily idled in 2009 and permanently shutdown in 2011. Since 2009, the power generated from Tapoco was sold into the open market. The net carrying value of the assets to be sold was $169 and $146 as of June 30, 2012 and December 31, 2011, respectively, which consist mostly of properties, plants, and equipment. These assets, along with an allocation of goodwill ($94) from the Primary Metals reporting unit, were classified as held for sale (included in Other noncurrent assets) for all periods presented on the accompanying Consolidated Balance Sheet.
