Video: Judith-Jasmin substation in Terrebonne
Welcome to the jobsite!
There aren’t many people who can say they’ve toured a transmission substation construction site.
Project manager Martin Lavoie takes us to Judith-Jasmin substation currently being built in Terrebonne.
The substation will meet electricity needs on three levels: local, regional and provincial.
At present, the project involves some 200 workers. Earlier stages from design through approvals involved the input of close to 1,000.
In April 2016, Hydro-Québec began construction of Judith-Jasmin substation in Terrebonne. This 735/120/25-kV substation is located north of the 640-Côté-Est industrial park. The substation will be able to transform more than 2,300 MW, enough to power about 800,000 homes. Commissioning will start in fall 2018 (for the 735-kV portion) and finish in spring 2019 (for the 120-kV portion).
Underground infrastructure work in Terrebonne
To deliver electricity to the surrounding area, Hydro-Québec will build a 24-km-long network of underground conduits, including three crossings under highway 640.
Construction, which began in spring 2017 in a number of sectors in Terrebonne, is now coming to an end. We would like to thank our customers for their patience and understanding.
In the boulevard des Entreprises sector, between chemin Gascon and Judith-Jasmin substation, construction will be completed between June and December 2018. To ensure the safety of workers and the public, traffic disruptions are necessary near the work site. One lane will remain open at all times, and access to businesses will be maintained.
In the boulevard des Seigneurs sector, between avenue Claude-Léveillée and rue Durocher, site restoration work will take place in spring 2018. This will be the final construction phase.
In the boulevard de la Pinière sector, up to avenue Urbanova, construction will take place from May to December 2018.
