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.
