Request a connection

You need your facilities connected to the Hydro-Québec power system.

Connection involves running a line from the power grid to your electrical system. The connection point marks where Hydro-Québec’s responsibility ends and yours begins.

Connection is always done by Hydro-Québec, and must be requested by a master electrician.

Service charges apply, depending on the scope of the work required.
