NEW YORK -- October 25, 2012

Alcoa (NYSE:AA) joined with Brazilian business and government dignitaries,
including President Dilma Rousseff, in the inauguration of the 1087-megawatt
Estreito hydroelectric power plant in Brazil. The power plant was developed by
the Estreito Power Consortium, comprised of Alcoa (25.49%), Tractebel Energia,
Vale and Intercement. With the Estreito facility, Alcoa will be 70 percent
energy self-sufficient in Brazil.

"Our investment in the Estreito power plant is an important part of our
strategy for seeking competitiveness for our operations in Brazil, since
energy is a fundamental input in the aluminum industry," said Franklin L.
Feder, Regional CEO of Alcoa Latin America & Caribbean. "The inauguration of
Estreito is ratification of Alcoa's commitment to Brazil and is a practical
demonstration of how the company is playing its part."

Construction of the facility began in 2007, and at the height of construction,
the development generated some 36,000 direct and indirect jobs.

"The five years were full of challenges on this huge project, which in
addition to supplying power for the whole of Brazil and for Alcoa's plants for
the next few decades, will stimulate regional development," said Ricardo
Sayão, Director of Energy for Alcoa Latin America & Caribbean.

The hydropower plant will supply reliable energy to Brazil's North/Northeast
power grid. Alcoa's share of the installed power is earmarked for the
company's Alumar facility.

Estreito is Alcoa's third power generating project in Brazil. Machadinho
(1,140 MW) has been running since 2002, and Barra Grande (708 MW) began
operating in 2005.
