Bridge River system upgrades

The Bridge River facilities have over 100 projects requiring refurbishment of aging equipment. We're upgrading it to modern standards with a project budget of nearly $400 million.

BC Hydro's Bridge River system is about 300 km north of Vancouver and consists of the Lajoie Dam and Powerhouse (Downton Reservoir), Bridge 1 and 2 Powerhouses (Terzaghi Dam and Carpenter Lake Reservoir) and Seton Dam and Powerhouse (Seton Lake).

Construction started in 2015, and is scheduled to complete in 2019.

We're planning more than 100 major projects in the system, including:

  • Generating unit upgrades at Bridge 2
  • Slope drainage improvements

Our Bridge River facilities are between 55 and 70 years old, and need to be updated.

The electricity generated on the system accounts for about 6% of BC Hydro's total generation. These facilities are capable of generating 550 MW of power but are currently restricted to less than 455 MW.

We're spending almost $700 million on facilities that are 55 to 70 years-old. This includes a number of projects in the region.
