Hydropower facility revealed

What are the main parts of a hydropower facility? You’ll find out at Jean-Lesage.

It’s one of the world’s largest gravity dams, with a hollow joint the size of a Boeing 747. You’ll see a 400-t rotor spinning over your head and feel the immense power of the eight generating units.

Be sure to visit the Georges Dor building to see an exhibition about the technology that revolutionized electricity transmission throughout the world.

Don’t miss it! Only 15 minutes from Baie-Comeau.

Question from: Marc, Chibougamau

Answer from: Carolane, tour guide at Jean-Lesage generating station

How long did it take to fill the Manic-2 reservoir?
Only six months, because it is fed by two rivers, the Manicouagan and the Toulnustouc.

Question from: Katia, Rivière-du-Loup

Answer from: Alexandra, tour guide at Jean-Lesage generating station

How much water circulates through the penstocks?
The penstocks are the huge pipes that channel water from the reservoir to the turbines. There are eight of them, each carrying 202 m3 of water per second. A penstock could fill an Olympic pool in just eight seconds.

Question from: Raymond, Montréal

Answer from: Valérie, tour guide at Jean-Lesage generating station

Where does electricity from Jean-Lesage generating station go?
The transmission lines carry the electricity to Manicouagan substation, where the voltage is stepped up to 735 kV. Three high-voltage lines then travel along a corridor to Lévis substation.
