Hydro owns a 20-percent interest in the Alumineria Alouette primary aluminium plant in Sept-Îles, Québec. The plant produces primary aluminium on two prebake lines.
In 2002, Hydro decided to participate in the expansion of the plant, which would make Alouette the largest aluminium plant in North America and among the world’s lowest operating-cost primary aluminium plants. The expansion project was completed in 2005.
