120-kV Grand-Brûlé – Saint-Sauveur Supply Line
GENERAL INFORMATION • Summer 2012
Municipality of Saint-Sauveur
Hydro-Québec must increase the transit and transformer capacity of certain substations that currently supply the heart of the Laurentides region to better meet the increase in electricity demand.
Many 120-kV substations can no longer handle the load. The same is true of some 120-kV transmission lines in the area; their capacity will be exceeded in the short term.
Hydro-Québec Équipement et services partagés will conduct the draft-design studies to build a new 120-kV line in the Laurentides area. Present situation Preferred solution Study area For the past few years, demand for To meet the expected growth in The study area of the 120-kV line electricity in the Laurentides region demand in Saint-Jérôme and the covers about 1,000 km2 and includes has continued to increase.
