In the heart of the boreal forest
On the edge of the Canadian Shield, in the heart of the boreal forest, lies the last of the La Grande Complex facilities: La Grande-1.
This run-of-river power plant, made of 640,000 m3 of concrete—enough to build a sidewalk from Montréal to Miami—will impress you with its drive shafts measuring over 2 m in diameter.
More than 6,000 workers helped build La Grande-1 generating station. You’ll be amazed to see how well it blends in with the natural environment.
Imposing and majestic!





Did you know?
Active workforce
Over 6,000 people helped build La Grande-1 generating station, commissioned in 1995.
Last, but not least
La Grande-1 is the last of nine facilities in the complex to harness the power of La Grande Rivière before it empties into Baie James (James Bay).
204 km/h
That’s how fast the rotors of each of La Grande-1’s 12 generating units turn.

You could also seize the opportunity to visit Robert A. Boyd Park, an exploration camp that has been recreated to show living conditions of the first workers at what was to become the La Grande complex. The park is open to groups from mid-May until the end of September.
