FORT ST. JOHN, B.C. – BC Hydro is calling the recent completion of Site C’s transmission lines a “major milestone.”

The installation of the second and final 500 kilovolt, 75 kilometre transmission line means the new Site C substation is now connected to the BC Hydro grid, according to BC hydro.

The lines will help generate clean energy for the rest of the province once Site C is generating electricity.

 The two 75 kilometre lines run along an existing right-of-way between Site C and the Peace Canyon generating station. Bc Hydro says the project’s first 500 kilovolt, 75 kilometre transmission line, along with the Site C substation, were both completed and energized in the fall of 2020.

 Since Allteck Line Contractors Inc started on this part of the project in summer 2018, crews have built more than 400 towers and strung lines over a total of 150 kilometres.

The two transmission lines are a major component of the Site C project, which also consists of the new 500 kilovolt substation and expanding the existing Peace Canyon 500 kilovolt gas-insulated switchgear to incorporate the two new 500 kilovolt transmission line terminals,” said BC Hydro.

 The company says work to complete three other 500 kilovolt transmission lines that will span one kilometre between the Site C generating station and Site C substation is still underway. This work is expected to be complete in 2023.
