Prince George to Terrace Capacitors Project
What's new
Work is ongoing at the three capacitor station sties. Construction of the Saranovich and Palling capacitor stations is expected to be complete in fall 2026 and construction of Walcott Capacitor Station is expected to be complete in fall 2027.
The Government of Canada is investing $96.95 million in the Prince George to Terrace Capacitors Project as part of a larger federal investment of nearly $157 million for eight BC Hydro projects. This funding is being provided through the Green Infrastructure stream of the Investing in Canada Infrastructure Program, which supports the reduction of greenhouse gas emissions and the expansion of clean energy.
We're working to increase the transfer capacity of the existing 450 km, 500 kilovolt (kV) transmission lines from Prince George to Terrace by constructing three new capacitor stations through the Prince George to Terrace Capacitors project:
- Saranovich Capacitor Station near Vanderhoof
- Palling Capacitor Station near Burns Lake
- Walcott Capacitor Station near Telkwa

We're also adding a transformer to Skeena Substation near Terrace to decrease the 500 kV electricity to voltages suitable for our customers. The work is entirely within the substation fence and expansion is not required.
A number of industries in the North Coast such as mining and liquefied natural gas (LNG) developments have requested power from us. We need to increase capacity along the existing 500 kV transmission line between Prince George and Terrace to meet the customers' needs.
A capacitor station contains equipment to boost the amount of electricity that a transmission line can carry. These stations are fenced, outdoor facilities that must be constructed on flat land, adjacent to or near the existing transmission line. Capacitor stations can significantly increase the capacity of the existing transmission line in a cost-effective, safe, and reliable way.
All three capacitor station sites have been prepared for station construction.
Concrete foundation installation for equipment and buildings is complete at Saranovich and Palling capacitor stations with electrical equipment installation and commissioning activities underway. Concrete foundation works are underway at Walcott Capacitor Station.
Additional detail on work completed to date and upcoming work is provided for each station below.
The expected overall project in-service date is 2028.
