Vancouver Island Power Boost
BC Hydro moves forward with Vancouver Island’s first 100-megawatt battery storage facility to boost grid reliability

Key Points
1
The provincial government is providing significant funding for the project as part of its renewable energy and emissions reduction commitments.
2
The site was chosen adjacent to the Vancouver Island Terminal Substation after evaluating reliability, costs, environmental considerations and potential impacts on surrounding communities.
3
The battery storage technology can respond within seconds, storing energy when demand is low and discharging during peak periods, and it is not intended to replace traditional generation.

BC Hydro's leadership frames the project as a significant step in modernizing the electricity system and leveraging storage technology to deliver power when needed, highlighting the upgrade as part of broader system improvements.
BC Hydro is moving forward with British Columbia's first utility-scale battery energy storage facility, to be built near Duncan on Vancouver Island, according to Victoria Buzz. The project will store at least 100 megawatts of electricity — enough to power tens of thousands of homes during peak demand periods.
The facility will sit on BC Hydro-owned land next to the Vancouver Island Terminal Substation in the Cowichan Valley. It is targeted to be operational by 2030 as part of BC Hydro's broader Powering Growth plan, Kelowna Capital News reported.
Why Vancouver Island Needs Battery Storage Now
Vancouver Island's population is growing, and so is its electricity demand. The island's grid needs more flexibility to handle busy periods when everyone draws power at once. Battery storage fills that gap by acting like a giant rechargeable reserve — charging up when demand is low and releasing power within seconds when it spikes.
BC Hydro is clear that battery storage is not meant to replace dams or other traditional generation. Instead, it works alongside existing power sources to keep the grid stable and reliable, Peace Arch News reported.
Cowichan Valley Site Chosen After Multi-Factor Review
BC Hydro evaluated several locations before settling on land it already owns adjacent to the Vancouver Island Terminal Substation. The utility weighed grid reliability, construction costs, environmental impacts, and effects on nearby communities, according to Clearwater Times.
Placing the facility next to an existing substation keeps connection costs low and limits the footprint of new development. BC Hydro says using land it already controls helps speed up the project and reduces the risk of delays.
Procurement Timeline: Bids Open Later in 2026
A formal procurement process is now underway. BC Hydro plans to issue supplier qualification documents on July 30, 2026. Only qualified suppliers will then receive a request for proposals later that same year, Victoria Buzz reported.
The provincial government is contributing significant funding to the project as part of its clean energy and emissions reduction commitments. BC Hydro's leadership described the initiative as a major step in modernizing the province's electricity system and laying the groundwork for future battery storage projects across British Columbia.
BC's Broader Push Toward Grid Modernization
This Duncan project is the first of what BC Hydro expects will be multiple utility-scale battery facilities across the province. The Powering Growth plan frames storage as a key tool for managing a grid that will handle more electric vehicles, heat pumps, and industrial loads in the coming decade.
Battery systems can respond in seconds — far faster than a dam or gas plant can ramp up. That speed makes them especially valuable for keeping the lights on during sudden demand surges. The 2030 target gives BC Hydro roughly four years to move from procurement to full operation, Clearwater Times noted.
