Robert-Bourassa generating station is one of the crown jewels in Hydro-Québec’s generating fleet. With an installed capacity of 5,616 MW, it is the most powerful generating facility in Québec. Its longevity is essential to ensuring the long-term supply of reliable power in Québec. This project includes the rehabilitation of eight of the sixteen generating units of the Robert-Bourassa generating station, as well as the speed governors, static excitation systems and cooling systems in all sixteen units. The DEW generating units (made by Dominion Engineering Works) will be the ones rehabilitated, as they show the most signs of wear. This work will allow Hydro-Québec. to optimize its facilities and adequately secure Québec’s energy future. Project completion is targeted for 2023, which will see such milestones as the final assembly of the seventh generating unit (out of a total of eight to be replaced).
