Peace to Kelly Lake Capacitors Project
We need to increase the capacity of the transmission system in the Peace Region to accommodate additional electricity being planned in the area. We're currently exploring three alternatives to address the area's needs.
The Peace Region currently generates more than 30% of the total electricity produced in the province. With new generation resources being planned, more electricity will be generated in the area in coming years.
We're in the early planning stages of the Peace to Kelly Lake Capacitors Project (PKCP) that will ensure the capacity and capability of the transmission lines can accommodate all expected generation in the Peace Region, avoiding the need to build a new transmission line.
We anticipate that the project will involve building up to four new capacitor stations – used to maintain system voltage levels and secure system performance – along the six existing 500 kilovolt (kV) transmission lines that run from the GM Shrum and Peace Canyon generating stations near Hudson’s Hope to the Kelly Lake Substation near Clinton.

What is a capacitor station?
A capacitor station is a facility where electricity from a high-voltage transmission line is carried through a series of devices called capacitors. This helps maintain the voltage levels in a transmission line, allowing more electricity to pass through a line over long distances.
Each capacitor station would be approximately four to five hectares in size. Depending on the locations, much of the station's footprint would be located within the existing right-of-way (the land under and around our power lines).
Please note that the final dimensions of the stations will vary depending on a number of factors such as environmental criteria, geotechnical conditions, etc.
As electricity moves along a lengthy transmission line, the voltage drops. This limits the amount of electricity that the line can move. Building capacitor stations will help maintain the voltage levels of the transmission lines, maximizing the amount of electricity the existing lines can move.
This project will also include upgrades to the aging equipment that needs to be replaced at the existing Kennedy Capacitor Station.
Completion of this project will ensure that our transmission system can safely and reliably move the electricity generated in the Peace Region to where it’s used in the Lower Mainland and Vancouver Island regions.
The project will ensure the capacity and capability of the transmission lines can accommodate all expected generation in the Peace Region, avoiding the need to build a new transmission line.
The four new capacitor stations could be located along the existing 500 kV transmission corridor between Hudson's Hope and Clinton at the following approximate locations:
- 100 kilometres southwest of Hudson's Hope (near Powder King Mountain Resort)
- 50 kilometres southeast of McLeod Lake
- Near Quesnel
- 15 kilometres south of Williams Lake
None at this time as the project is in the early planning stages.
We're currently in the very early planning stages of this project and don't expect to start any construction activities until 2021. Project completion will depend on the final alternative and scope selected. At this time the project is expected to be complete between 2024 and 2026.
Potential environmental effects are a key aspect we assess when evaluating project alternatives.
While the scope of the project is still being defined, we anticipate completing an environmental overview assessment that will consider the potential environmental effects of each alternative.
The overview assessment will help us compare the potential social and environmental impacts of each alternative as we look to identify a leading alternative in early 2019. In the next stage of the project, we'll carry out field studies to define the social and environmental baseline conditions and potential impacts of the leading alternative.
Regulatory requirements for environmental impacts for this project are still being defined.
We'll share more information on these studies as it comes available.
We're currently exploring three alternatives for the project and began consultation with First Nations, local governments, and residents in April 2018.
