Potential La Grande capacity upgrades
The generating units at Robert‑Bourassa, La Grande‑3 and La Grande‑4 generating stations in Eeyou Istchee Baie‑James must be replaced, which makes it possible to consider increasing their installed capacity. Hydro‑Québec is working closely with the Cree and Jamesian communities to assess the impacts of higher flow rates while maintaining current operating levels, in compliance with the parameters set out in the James Bay and Northern Québec Agreement.
