Project summary

Chantier du nouveau poste d’Adamsville – Octobre 2015
Adamsville substation – September 2016

In May 2015, Hydro-Québec began construction of a new 120/25-kV substation on Boulevard de Montréal in Bromont. The substation will be connected to Cleveland substation, in Granby, by a new 120-kV double-circuit line that will be 8.3 km long. These additions to Hydro-Québec’s transmission network are intended to meet the region’s growing demands for electricity.

Since the line and the substation have been commissioned in september 2016, it is now possible to plan the dismantling of the current Bromont substation, located on Rue de Gaspé, along with the equipment at Cleveland substation. Many kilometers of the 49-kV line will aslo be dismantled.

Several overhead and underground additions and modifications will be made to the distribution system to serve the region’s customers.
