Project overview

Visual simulation of proposed Patriotes substation

The project

Hydro-Québec plans to build a 315/25-kV substation in Saint-Eustache and a 315-kV supply line to meet the growing needs of Saint-Eustache, Deux-Montagnes and Sainte-Marthe-sur-le-Lac. La Trappe and Saint-Eustache substations, which currently supply the area, no longer provide the capacity and reliability required to support urban development.

Commissioning of the new equipment is planned in 2020. The new Patriotes substation will be located in Saint-Eustache’s industrial sector. A new 315-kV supply line will connect the planned substation to the existing 315-kV line located north of Boulevard Arthur-Sauvé.
