BC Hydro and FortisBC will be working together to connect the Westbank substation to the FortisBC system in Kelowna to provide about 70,000 people with an additional source of power.
The connection will involve the construction of a new transmission line, including an underwater cable across Okanagan Lake.
BC Hydro said in a news release that a second source of power is needed due to the current substation’s remote location, rough terrain and the size of the 80-kilometre transmission line, which is at risk during wildfire seasons.
The Westbank substation is currently supplied by a single 138-kilovolt transmission line from the Nicola substation near Merritt and serves Westbank First Nation, West Kelowna, Peachland and parts of Summerland.
The FortisBC connection was chosen as a leading alternative power source following ongoing consultation with the Sylix Okanagan Nation and local governments, said the release.
BC Hydro and FortisBC have signed a memorandum of understanding to guide the project.
“Selecting the FortisBC connection as the leading alternative offers several benefits, including a second source of power, with lower risk of impacts including wildfires, smaller footprint, minimizes habitat loss and fragmentation, and could be in service sooner than the other alternatives,” said Chris O’Riley, president and CEO of BC Hydro.
Roger Dall'Antonia, president and CEO of FortisBC, said the proposed new transmission line will help to improve the reliability and resiliency of the electricity system for many Central Okanagan homes and businesses.
Both companies will also be working with Westbank First Nation, Okanagan Indian Band and Upper Nicola Band to ensure impacts to First Nation rights and tiles are minimized, the news release said.
Next steps will see BC Hydro develop a project schedule early next year, which will include community open houses and other engagement activities.
