EDMONTON, Alberta, Sept. 22, 2025 (GLOBE NEWSWIRE) -- Capital Power Corporation (TSX: CPX) (“Capital Power”) is pleased to announce that its 120-MW York Battery Energy Storage System (“BESS”) and 50-MW Goreway BESS projects (“the projects”) have successfully achieved commercial operations. A leader of Ontario’s BESS development, Capital Power delivered both projects on time, under budget and with an excellent safety record. Combined, both projects will add roughly $35 million in contracted annual EBITDA for over 20 years. The projects are contracted until 2047 with the Ontario IESO (part of their Expedited Long-Term 1 RFP process).

“We’re proud to deliver our first-ever battery storage projects. These facilities enhance our portfolio of flexible generation sources that provide grid stability, support the integration of renewable resources, and meet the province’s unprecedented, growing demand for electricity,” said Jason Comandante, Senior Vice President, Head of Canada. “Grids that strike a balance of being reliable, affordable, and lower-carbon are the foundation of our economy – they serve existing customers and facilitate economic growth.”

“Ontario launched the largest energy procurement in provincial history, with one goal: keep power affordable and always reliable for families. I am encouraged to see companies like Capital Power rising to the challenge and expanding their presence in our province as we launch the York and Goreway Battery Energy Storage Systems,” said Hon. Stephen Lecce, Minister of Energy and Mines. “These investments will help deliver affordable, reliable, and clean electricity that supports families, farms and businesses in the GTA, and beyond."

As utility-scale BESS deployment rapidly expands worldwide, these projects reinforce Capital Power’s position as a North American leader in the energy expansion, ensuring people and communities are supported through a reliable and lower-emitting electricity system. Together, the projects will provide up to 170 megawatts of storage to deliver power when Ontarians need it most.

Capital Power worked closely with the City of Brampton, the Township of King, Indigenous Nations, and local residents throughout the planning process, and after nearly 12 months of construction, the completion of these projects reflects the dedication of over 183,000 person-hours of work, a testament to the skilled trades and professionals who made this possible.
