Construction of the 315-kV tie line (October 28, 2014).

A gradual increase in the total capacity of the substations on Hydro-Québec’s transmission system was required to meet increasing demand on Montréal's north shore.

To meet part of this increasing demand, Hydro-Québec recently completed the new Blainville substation and its connection to the transmission system.

The new facilities were commissioned in summer 2015.

Hydro-Québec would like to thank residents and regional organizations for their participation in the public participation process.
