Judith-Jasmin substation

Visual simulation of Judith-Jasmin substation

In April 2016, Hydro-Québec began construction of Judith-Jasmin substation in Terrebonne. This 735/120/25-kV substation is located north of the 640-Côté-Est industrial park.

This new substation has two objectives:

  • Meet the growing demand for electricity on the north shore, including the regional county municipality of Des Moulins. In the Mascouche and Terrebonne areas, the demand for electricity is experiencing strong growth, due in large part to the Urbanova major residential development and the new Mascouche commuter rail line.
  • Connect the new line from Chamouchouane substation in the Lac-Saint-Jean region.

To supply electricity to the surrounding areas, Hydro-Québec will build a network of underground conduits some 24 km long, which will include crossing under Highway 640.

An optimal solution for the Terrebonne area

The new sustation will reduce the number of lines in the existing right-of-way leading to Duvernay substation in Laval, thereby minimizing the impact on the woods surrounding the TransTerrebonne bicycle path. In addition, by combining the infrastructure north of Highway 640, Hydro-Québec will not have to build a substation near residential areas.
