Alcoa′s Leadership in Energy Efficiency Recognized by Hydro-Quebec

Alcoa (NYSE: AA) announced today that its three aluminum smelters in
Quebec, Canada, have been recognized by Hydro-Quebec for their energy
efficiency, and are members of the power company′s select Energy Savers′
Circle network.

Alcoa′s Deschambault smelter was just raised to Elite status, having
been a member of the Energy Savers′ Circle since 2008, and the
Baie-Comeau smelter was newly inducted into the Circle. Last year, the
B?ncour plant was named an Elite component of the Energy Savers′
Circle. Furthermore, Alcoa′s Deschambault and B?ncour plants are two
of only five locations designated Elite members because of their
exceptional energy performance and are deemed ambassadors in energy
efficiency.

'The distinction of having all of our Canadian smelters as members of
Hydro-Quebec′s Energy Savers′ Circle crowns our employees′ efforts in
energy efficiency and clearly sets our commitment to sustainability,?
said Pierre Morin, President of Alcoa Global Primary Products Canada. 'I
congratulate the Energy Committees in our smelters and our employees who
make a "green′ gesture every day, so that our facilities become a
reference in energy efficiency.?

• 
  Alcoa′s Baie-Comeau aluminum smelter joined the Energy Savers′ Circle
  by reducing its annual power consumption by more than
  68  gigawatt-hours (GWh) through improved performance of its
  electrolytic cells and optimizing its compressed air system.
  
• 
  Deschambault was awarded Elite status after lowering its annual
  electricity use by more than 300 GWh ?equivalent to the consumption of
  18,000 Quebec households in a year.
  
• 
  Alcoa′s B?ncour smelter, the first Alcoa smelter to attain Elite
  status, reached new heights in effectiveness by accomplishing energy
  efficiency gains of more than 250 GWh. The smelter acted on its
  consumption of compressed air, motive power, heating and lighting of
  facilities, as well as power used for its electrolytic cells.
  

Between 2007-2010, Alcoa′s Canadian smelters posted total cumulative
energy efficiency gains of more than 600 GWh. In addition, both the
B?ncour and Deschambault facilities received awards for their energy
efficiency initiatives in the 2011 Énergia competition, organized by
l′Association qu?coise pour la maîtrise de l′?rgie (AQME).

To continue enhancement of its environmental balance sheet, Alcoa Global
Primary Products Canada contributed to the establishment of the Natural
Sciences and Engineering Research Council of Canada/Alcoa Industrial
Research Chair on Energy Efficiency and the Advanced Modeling of
Aluminum Electrolysis Cells. The chair at Laval University in Quebec
City, which has benefitted from the financial support and services of
Alcoa and its global research fund, enables 40 students to develop
technologies that reduce energy consumption and optimize the aluminum
production process, thus reducing CO2 emissions.

A select network of Qu?c companies

Established in 2005, Hydro-Quebec′s Energy Savers' Circle has more than
50 members, all leaders in energy efficiency. The circle brings together
Hydro-Quebec's large power customers that have reduced their electricity
usage by at least 5% or saved at least 50 million kWh. To learn more
