Prince George to Terrace Capacitors Project

Capacitor station

What's new

We’ve selected the location for the third capacitor station (CAP3). Three areas were considered: near the existing Telkwa Substation, near Quick, and adjacent to the existing Telkwa Substation. The area adjacent to Telkwa Substation was selected as it has less impacts to Indigenous interests and archaeological and environmental features, less safety and reliability risks, and less costs compared to the other two options. This site will be an extension of the Telkwa Substation.

To meet the needs of the industries in the North Coast such as Liquefied Natural Gas (LNG) developments, we’re proposing to increase capacity along the existing 500-kilovolt transmission line between Prince George and Terrace. This project is required for Cedar LNG, a proposed floating liquefied natural gas (FLNG) facility in Kitimat, British Columbia, Canada, within the traditional territory of the Haisla Nation..

The project involves constructing three new capacitor stations to increase the capacity along the 450-km, 500-kilovolt transmission line that runs between Prince George and northwest B.C.:

  • One station near Vanderhoof;
  • One station near Burns Lake;
  • One station near Telkwa.

Two of the three capacitor station sites are owned by BC Hydro. They’re located near Vanderhoof (CAP1) and Burns Lake (CAP2). The work at the Skeena substation is entirely within the substation fence and expansion is not required. The site for the third capacitor station (CAP3) was recently selected with the active participation of Indigenous Nations. Three areas were considered: near the existing Telkwa Substation, near Quick, and on Hungry Hill adjacent to the existing Telkwa Substation.

The area adjacent to the Telkwa Substation was selected as it has less impacts to Indigenous interests and archaeological and environmental features, less safety and reliability risks, and less costs compared to the other two sites. This site will be an extension of the Telkwa Substation.

We'll also be adding a transformer to the Skeena Substation near Terrace to decrease the high voltage 500-kilovolt electricity to voltages suitable for downstream customers.

Capacitor stations contain equipment to boost the amount of electricity that a transmission line can carry. These stations are fenced, outdoor facilities that need to be constructed on flat land, adjacent to or near the existing transmission line. By using capacitor stations we can significantly increase the capacity of the existing transmission line in a cost-effective, safe, and reliable way.

Project construction is expected to start in July 2023 at the earliest and the project in-service date is 2027.
