Rio Tinto will invest a further C$92 million to improve the reliability and efficiency of its Isle-Maligne hydroelectric station, which is essential to the production of hydroelectricity for the manufacture of low-carbon aluminium in Saguenay–Lac-Saint-Jean, Quebec.

Rio Tinto – Canada’s largest private producer of hydroelectricity – produces some of the world’s highest quality and lowest carbon aluminium at its operations in Quebec, which are powered with 100% clean, renewable hydroelectricity.

Located in Alma – a town in the Canadian province of Quebec – the company’s Isle-Maligne hydroelectric station was commissioned 95 years ago and is the oldest in Rio Tinto’s hydroelectric network, which consist of seven hydroelectric facilities, all of which are located in Quebec and British Columbia.

Sébastien Ross, Managing Director of Rio Tinto’s Quebec operations, said the plant will be upgraded with state-of-the-art instrumentation and information management technologies to deliver improved operational efficiencies.

“This work at the Isle-Maligne power plant represents a major investment by Rio Tinto in the region that will enable us to continue our hydroelectric operations and maintain our low-carbon footprint aluminium production in Quebec,” he said.

According to the company’s statement, GE Renewable Energy will deliver engineering, fabrication and installation of the replacement turbine-alternator group, with the project to provide employment for more than a hundred workers at the peak of the work.
