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.

Question from: François, Chibougamau
Answer from: Claude, tour guide at La Grande-1 generating facility
Why is it called La Grande-1 when it was the eighth generating station commissioned?
Generating stations are named for their locations in relation to the mouth of the river, not the order in which they were built. The facility’s name shows that it’s the first on La Grande Rivière, closest to Baie James (James Bay).
Question from: Sylvain, Mont-Laurier
Answer from: Francis, tour guide at La Grande-1 generating facility
What animals are there in the Baie-James (James Bay) region?
There are no fewer than 39 species in the region, including caribou, beaver, muskrat, black bear, Canada goose and various kinds of ducks. Near La Grande-1, in the Baie d’Upichiwuun, you can even see osprey nests.
Question from: Louise, Québec
Answer from: Francis, tour guide at La Grande-1 generating facility
Why is La Grande-1 so different from Robert-Bourassa?
La Grande-1 is a run-of-river generating station, while Robert-Bourassa is an underground facility with a reservoir. It was decided to build this type of power plant because of the local topography, which made a large reservoir impossible. Since there is no reservoir, the river water has to flow directly through the turbines as it arrives.

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.
