Hydro-Québec operates the world's second largest hydroelectric complex – La Grande, at James Bay, with an installed capacity of 16,500 MW.
Québec’s vast hydraulic resources, coupled with our own extensive, state-of-the-art power system, guarantee a stable supply of low-cost power.
A heritage pool of 165 TWh of electricity at a known fixed cost has been set aside for Québec customers.
Hydro-Québec has committed to increase its generating capacity in order to meet future demand. We plan to invest C$5 billion in hydroelectric projects between 2009 and 2013.
Ongoing efficiency enhancement programs have been implemented at all our major operating facilities to ensure long-term operability.
To diversify its sources of supply, Hydro-Québec purchases electricity from independent power producers in Québec as well as on regional markets in northeastern North America.
System reliability
Hydro-Québec received an award for the most outstanding technological innovation of the 20th century: 735-kV transmission.
Hydro-Québec’s power system meets the quality and reliability criteria of the Northeast Power Coordinating Council (NPCC), which are among the most stringent in the world.
We are constantly maintaining and upgrading our system in order to improve service continuity and power quality.
