This project involves the construction of transmission lines needed to connect the 1,550-MW Romaine Complex to the rest of the grid in Quebec. The project includes building more than 500 kilometres of transmission lines, designed for both 315 kV and 735 kV but operated at 315 kV, constructing new switchyards at the generating stations, and modifying and adding equipment in existing facilities.
The transmission line is a separate venture from the Romaine Complex project. Construction has been underway since summer 2011, and is expected to be completed by 2020.
