MONTREAL, May 16, 2025 /CNW/ - AtkinsRéalis Group Inc. (TSX: ATRL), a world-class engineering services and nuclear company with offices around the world, announced today that it has been awarded a seven-year contract by Rio Tinto for the refurbishment of the Isle-Maligne hydropower plant in Alma, Quebec. AtkinsRéalis will provide execution engineering, integrated procurement, and construction management services to extend the hydropower plant's operational life for decades to come.
