Growing electricity needs in the Laurentides
Electricity needs in the Pays-d’en-Haut and Laurentides regional county municipalities (MRCs) have grown by 20% between 2004 and 2012, and continue to increase. The annual growth of electricity demand is twice the Québec average.
Several substations and supply lines that are part of the Laurentides’ regional transmission system have reached their capacity.
Hydro-Québec has the obligation to meet the current and future needs of the region. The company plans its network for the long-term and ensures that the network evolves adequately to meet electricity needs.
A new line to sustain development in the region
To sustain the region’s economic, residential, commercial and tourism development and meet its electricity needs for the next 20 years, Hydro-Québec will build a 120-kilovolt (kV) line connecting Grand-Brûlé substation, in Mont-Tremblant, to an existing 120-kV line, running between Saint-Sauveur and Sainte-Agathe-des-Monts substations.
This new line will supply the existing Saint-Sauveur and Doc-Grignon substations, as well as a substation planned for Chertsey, in the Lanaudière region. Separate draft-design studies will be carried out for the Chertsey substation project. Commissioning is planned for 2018.
