High-voltage power lines, Boucherville, Québec, Canada 

When you’re this reliable, word gets around.

Hydro-Québec is known throughout the world for the reliability of its transmission system, and we’re committed to remaining a benchmark. Thanks to redundancy across the looped grid and annual investments of C$2 billion, Hydro-Québec’s infrastructure is built for dependability and high performance. Hydro-Québec also relies on its own extensive and robust telecommunications network to manage, monitor and operate its facilities.

Since our grid is electrically isolated from the rest of the North American power system, it’s safe from disturbances and outages that may occur on neighboring systems. In addition, a loop comprising seven 735-kV substations circles the Greater Montréal area, ensuring a reliable supply of electricity.
