Achievements

  • Anjou Substation and 315 kV Transmission Line
    Anjou,
    Quebec, Canada
    2024

    Anjou Substation and 315 kV Transmission Line

    To meet the growing demand for electricity and address the aging of its transmission network on the Island of Montreal, Hydro-Québec started gradually replacing its 120 kV facilities with new, higher capacity 315 kV facilities spanning approx. 11 km between the Bout-de-l’Île Substation and the Bélanger Substation supply line, located near Viau Boulevard.

  • Appalachian-Maine Interconnection
    Thetford Mines - Lac-Mégantic,
    Quebec, Canada
    2024

    Appalachian-Maine Interconnection

    The project was to build an interconnection line between the Hydro-Québec electricity grid and the one in Maine to increase exchange capacity between Quebec and New England. It involved building a power transmission line of approx. 100 km between the Appalachian Substation, located in Saint-Adrien-d’Irlande near Thetford Mines, in the Chaudière-Appalaches region, and a connection point at the border between Quebec and Maine. This new direct current interconnection line, with a voltage of 320 kV, will connect to the New England Clean Energy Connect transmission line that will be built in the State of Maine.
