Our Expertise in Battery Storage
We entered the battery storage sector in 2022 with our majority investment in the 250 MW / 1,000 MWh Oneida Energy Storage project in Ontario. In April 2025, Oneida entered commercial operations ahead of schedule, under budget, and with zero lost-time incidents.
Since then, we have continued to scale our battery storage platform, bringing the 80 MW / 160 MWh Jurassic BESS project in Alberta into commercial operations and progressing 300 MW / 1.2 GWh of battery storage projects in Poland into construction. Together, these projects strengthen our expertise as a developer, builder, owner and operator of large-scale energy storage assets and position us for continued growth in this rapidly expanding sector.

Battery energy storage systems (BESS) are capacity resources that work to store surplus energy from electricity grids during off-peak hours and release it during peak hours, enhancing system stability and reliability. Storage supports renewable energy integration, and helps strengthen electricity grids to meet growing energy and capacity needs.
The Oneida Energy Storage Project stands as a landmark in Canada’s growing energy storage sector and a blueprint for future storage developments. Built through a groundbreaking partnership between Northland Power, Six Nations of the Grand River Development Corporation (SNGRDC), NRStor, Aecon and Mississaugas of the Credit Business Corporation (MCBC), the project demonstrates the power of collaboration between industry and Indigenous communities.
With 278 battery packs supported by 170 transformers, Oneida is among the most advanced storage facilities in the country with the ability to power a city the size of Oshawa for one hour. Built by a local workforce, construction required over 300,000 hours on site and the dedication of 40 local Indigenous workers, underscoring its role as both a technological achievement and a community-driven project.
