Visit the Robert‑Bourassa generating facility (La Grande‑2)!

Eeyou Istchee Baie-James, QC

Reservations and practical information

Aerial view of the Robert‑Bourassa facility (previously La Grande‑2), including the spillway, dam and reservoir

The largest hydropower generation facility in North America

I’m part of the “project of the century,” and it was called that for a good reason! To give you an idea, the La Grande complex generates half the electricity consumed in Québec.

I’m the most powerful underground generating station in the world and Hydro‑Québec’s most powerful. No less!

My spillway is gigantic and my dam is as high as a 53‑storey building. Feeling dizzy yet? As for my reservoir, each of the Earth’s inhabitants could draw 10,000 litres of water from it before it ran dry. Imagine the size!

It was Premier Robert Bourassa who came up with the idea of building the La Grande complex in Baie‑James. That’s why I was renamed the Robert Bourassa generation facility after having been called La Grande‑2 for years.

When humans put their minds to it, they can be quite ingenious. I’m proof of that! If you’re heading for Baie‑James, come see me! I promise you’ll be blown away, and you’ll get to admire awe-inspiring northern landscapes along the way. See you soon!

Feast your eyes!

Did you know?

Colossal dimensions

My spillway was designed like a giant staircase to reduce water velocity and prevent erosion. Each of its 10 steps is as big as two football fields and 10 metres high!

Where there once was no road

When the “project of the century” was taking shape, there was no road to get to the construction site. To transport materials, equipment and workers, a 620‑km road was built in the space of three years. A record! It was inaugurated in 1974 and connects Matagami to Radisson. You’ll drive on it to come see me.

Over 100,000 names!

The Parc commémoratif des Bâtisseurs is a tribute to the exceptional contribution of the workers who built northern Québec’s hydropower facility. More than 100,000 names of those who helped build the La Grande complex have been immortalized on panels.

My history

Before I became the most powerful underground generating station in the world with my 5,616‑MW capacity, there were those who fervently believed in developing hydropower in Baie‑James. It was a long journey!

1944: First phase of electricity nationalization in Québec

1960: Beginning of the Quiet Revolution in Québec

1963: Second phase of electricity nationalization in Québec

1971: Launch of the “project of the century”

In April 1971, Premier Robert Bourassa launched the “project of the century” in Baie‑James (me!). One year later, the river that would be used was chosen: the La Grande river. It was the beginning of the huge construction sites that resulted in the La Grande complex.

“Never let it be said that we shall live like paupers on a land this rich”
said Robert Bourassa, the “father of James Bay,” when he announced the hydropower megaproject in Baie‑James on April 30, 1971.

1973: Construction begins at La Grande‑2 generating station

Construction, which began in 1973, continued for more than four decades, in a vast territory in mid‑northern Québec. In the beginning, newly arrived employees slept in tents heated by a wood stove. Gradually, the work camp turned into a small town. At the height of the work, many services were offered to the 6,000 people who worked there, but what left a lasting impression was the huge cafeteria and the colossal number of meals served every day. For breakfast alone, more than 10,000 eggs and some 4,000 steaks were cooked!

1974: Arrival of women in Baie‑James

In the summer of 1974, a first contingent of women workers landed in Baie‑James. When the project began, there were less than 40 women among nearly 5,000 men. They were nurses, administrative assistants and cooks. Specialized employees would soon join them. They slept in dormitories that men were prohibited from entering on pain of expulsion.

1975: Signing of the James Bay and Northern Québec Agreement

After lengthy negotiations, the Cree and Inuit populations agreed to the development of Baie‑James’s rivers and signed the James Bay and Northern Québec Agreement on November 11, 1975. The Québec government recognized their hunting and fishing rights and granted them financial compensation.

1976: First time the Parti Québécois is elected

1979‑1981: La Grande‑2 generating station is commissioned

In October 1979, Premier René Lévesque commissioned the first generating unit at La Grande‑2 generating station (me!), the first in the La Grande complex to generate electricity. At 137 metres underground, I became the largest underground generating station in the world, and Hydro‑Québec’s most powerful.

1996: La Grande‑2 changes names

After Robert Bourassa, the father of the project of the century, passed away, I was renamed “the Robert‑Bourassa generating facility” in his honor.

2002: The Paix des Braves is signed and work on the Eastmain generating stations begins

The Paix des Braves paved the way for the development of the Eastmain‑1, Eastmain‑1‑A (renamed Bernard‑Landry after his passing) and Sarcelle generating stations, with a partial diversion of the Rupert. Today, the La Grande complex, which I’m a part of, has 11 hydropower generating stations and 9 reservoirs.

It’s well worth the trip!

Don’t take our word for it: this is what the people who visited the generating station with our guides had to say.

Remarkable, friendly and competent guide who explained things very clearly. She made me want to tour other Hydro‑Québec facilities.

Very interesting and rewarding tour. A lot of information on many subjects related to the generating station.

An extraordinary visit. Bravo!
