Bridge River Transmission Project

What's new

We're currently in the process of upgrading our Bridge River generating facilities located near Seton Portage to restore their capacity. The Bridge River Transmission Project will improve reliability and safety of the Bridge River transmission system by eliminating system constraints and increasing its capacity for future generation.

In July, we applied for a joint Certificate of Public Convenience and Necessity (CPCN) with the Bridge River Generator Replacement Project. We anticipate a decision on the application by mid-2022. More information on the CPCN process is available at

In addition to participating in the CPCN process over the coming months, we’ll be conducting more in-depth studies and design work to confirm the preferred alternative for the project by mid – 2022.

The Bridge River Area Transmission Project will ensure that we continue providing clean, reliable electricity to communities in southern B.C.

In June 2020, we completed our evaluation of the project alternatives and selected Alternative 1: Upgrades to an existing power line in Lillooet as the leading alternative. Key aspects of our assessment included: costs, system reliability, safety, environmental impacts, stakeholder interests, schedule, constructability and maintenance. 

The project will upgrade approximately 135 structures and raise the height of an existing line in several sections between Kelly Lake Substation and Bridge River Terminal Station. Work will also include upgrades to existing access roads and the creation of some new roads to access the structures. Most of the work will be within existing BC Hydro right-of-way (the land under and around our power lines).

We're in the early planning stages of this project. Construction is anticipated to  be completed by fall 2025.

Maintenance work on the existing line between Kelly Lake Substation and Bridge River Terminal Station will occur as needed, regardless of the selected alternative, over the coming years.

We'll keep local governments, residents and businesses located near each alternative informed of this project through regular communications and gather input at key milestones.
