Rio Tinto Investing in Isle-Maligne Power Plant in Quebec
Rio Tinto is investing a further CAD 92 million in maintenance work and upgrades to improve the reliability and efficiency of its Isle-Maligne
Rio Tinto is investing a further CAD 92 million in maintenance work and upgrades 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 aluminum in Saguenay–Lac-Saint-Jean in Quebec. The work will work begin this summer and take place over two years, with one turbine-alternator group being replaced and major maintenance work undertaken on another. The plant will be upgraded with state-of-the-art instrumentation and information management technologies to deliver improved operational efficiencies.
GE Renewable Energy will deliver engineering, fabrication and installation of the replacement turbine-alternator group.
The investment adds to a CAD 160 million maintenance project announced in October 2020 to replace valves in the Isle-Maligne station.
Rio Tinto is Canada's largest private producer of hydroelectricity. Its seven hydroelectric facilities, located in Quebec and British Columbia, provide a competitive advantage, allowing the company's modern aluminum smelters to position themselves favourably in the industry.
