Construction work, December 2016

To meet increasing demand and ensure the long-term operability of facilities in the eastern part of downtown Montréal, Hydro-Québec is currently converting De Lorimier substation to 315/25-kV on the site of the current 120/12-kV substation.

Hydro-Québec has built two 315-kV underground lines, about 7 km each, to connect the new De Lorimier substation (near Pont Jacques-Cartier) to Viger substation (near Pont Victoria).

Once commissioned, the new substation and its tap lines will meet the short- and long-term electricity needs of the area they serve.
