Alcoa to Sell Tapoco Hydroelectric Project to Brookfield Renewable Energy Partners

Alcoa (NYSE:AA) ?announced today that it has reached an agreement to sell
its 351-megawatt Tapoco Hydroelectric Project to Brookfield Renewable
Energy Partners.

Tapoco is a four-station hydroelectric project located on the Little
Tennessee and Cheoah Rivers in eastern Tennessee and western North
Carolina, and is operated by Alcoa Power Generating Inc., a wholly owned
subsidiary of Alcoa. The transaction will include the four generating
stations and dams, 86 miles of transmission line, and about 14,500 acres
of land associated with and surrounding Tapoco.

Alcoa anticipates receiving proceeds of $600 million from the sale upon
closing, which is subject to customary federal and state regulatory
approvals. The transaction, which involves non-core assets, is expected
to close by year-end.

Tapoco is licensed by the Federal Energy Regulatory Commission (FERC).

Tapoco was originally developed by Alcoa to provide power for its
aluminum smelting and rolling mill operations in Alcoa, Tenn. The four
dams ? Calderwood, Santeetlah, Chilhowee and Cheoah ? came into service
between 1919 and 1957.

J.P. Morgan advised Alcoa on the transaction.
