120/25-kV Vaudreuil-Soulanges Substation

The construction of the new Vaudreuil-Soulanges transformer substation and its tie line, which began in October 2008, was completed in November 2009. Located in the Town of Saint-Lazare, this 120/25-kV substation has been in service since December 15, 2009. It was built to supply Saint-Lazare, Hudson and part of Vaudreuil-Dorion, as well as to meet the growing power needs of the RCM of Vaudreuil-Soulanges.

The work was carried out in three distinct phases:

• From October to November 2008, the access road was built and the earthwork required for the substation's lower foundation was performed.
• From December 2008 to March 2009, the work performed included the installation of the piles, setting up of the equipment and construction of the control building.
• From August to November 2009, the assembly and installation of electrical equipment was completed. The configuration of the Dorion-Rigaud line was also modified in order to connect the substation to the transmission and distribution systems.

The different phases of the project were completed on schedule and within the allotted budget of 29 million dollars.

Hydro-Québec wishes to thank the Town of Saint-Lazare, the RCM of Vaudreuil-Soulanges, local economic and environmental organizations and the residents of Saint-Lazare for their cooperation throughout the entire project.
