Hydro-Québec’s 315/25-kV Bélanger Substation
This new 9665 m2 substation for Hydro-Québec is located in a residential area in the borough of Rosemont-la-Petite-Patrie.
Scale
10 000 m² / 100 M$
Completion
2010 — 2015

The station is composed of three volumes: a control station, a manoeuvring station and an electrical room isolated with SF6 gas.
The building’s exterior will be made of brick, aluminum and curtain walls. The architectural style is sober, and the materials chosen will ensure the building’s durability.


SF6 gas circuit breakers allow for enhanced management of electrical distribution on dense and odd-shaped sites. Because they are quieter and more space efficient than compressed-air circuit breakers, they are often used in urban substations. As it is the case for Henri-Bourassa and De Lorimier substations, the site was freed from old pieces of equipment thanks to the greater efficiency of the new pieces.
