Located in Alma, the plant was commissioned 95 years ago and is the oldest in Rio Tinto's hydroelectric network
Rio Tinto is investing a further C$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, Quebec.
Located in Alma, the plant was commissioned 95 years ago and is the oldest in Rio Tinto’s hydroelectric network.
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.
Sébastien Ross, Managing Director of Rio Tinto’s Quebec operations, said: “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.”
The project is expected to generate C$75 million in economic activity in Quebec and more than a hundred workers will be involved at the peak of the work.
GE Renewable Energy will deliver engineering, fabrication and installation of the replacement turbine-alternator group.
The investment adds to a C$160 million maintenance project announced in October 2020 to replace valves in the Isle-Maligne station.
