Rio Tinto surprised the market with a $1.2 billion investment. This investment will go toward the modernization of the century-old Isle-Maligne hydroelectric generating station in Alma, Quebec. The nine-unit initiative is the company’s biggest bet on hydroelectric assets since the 1950s. It is expected to greatly increase the production of low-carbon aluminium in the area.
The Isle-Maligne plant, which went into operation in 1926, is an important part of Rio Tinto’s hydroelectric portfolio. Today, the company operates seven hydroelectric plants across the provinces of Quebec and British Columbia. That makes it one of the largest private producers of hydroelectricity in all of Canada. This investment is noted as an example of the firm’s commitment to advancing sustainable energy production. It demonstrates their strategic commitment to remaining competitive in the business of aluminium manufacturing.
The modernisation project aims to secure the future of low-carbon aluminium production in the Saguenay–Lac-Saint-Jean region, which is vital for meeting global demands for environmentally friendly manufacturing practices. The major rehabilitation project will install eight new turbine-alternator sets. It will replace water intake and hydraulic channels, build new facilities and upgrade electrical and mechanical equipment.
The project is planned to extend through 2032. At full build out, it will employ more than 300 people on-site, further demonstrating the size and complexity of this monumental undertaking. Rio Tinto operates port facilities in Sept-Îles, Quebec. These facilities benefit from hydropower produced by an extra generating station. This comprehensive strategy enhances productivity. It contributes to climate goals by lowering carbon emissions in the aluminium production chain.
Rio Tinto’s investment in the modernisation of the Isle-Maligne hydroelectric power plant mirrors the company’s overall dedication to sustainability and innovation. The company is greening its hydroelectric assets to augment its capacity to produce some of the world’s lowest carbon aluminium. This move will only deepen its leadership position in the industry.
