The Sanjgon Battery Energy Storage Facility (formerly known as Tilbury Battery Storage) in Lakeshore, Ontario, officially held an inauguration ceremony on April 13 for the 80MW/320MWh project.
The facility stands as Barton Malow Canada’s largest built battery energy storage facility in the province and reached substantial completion in 2025. Developed by Boralex in partnership with Walpole Island First Nation, the facility aims to provide stability to Ontario’s electrical grid, support renewable energy integration, and deliver reliable power during peak demand.
With more than 70,000 work hours and zero lost-time incidents, Barton Malow successfully delivered the project featuring 89 Tesla Megapack units and four hours of full-power storage.
The name “Sanjgon,” derived from the Nishnaabemwin language, honors traditional storage practices of Walpole Island First Nation families and the project’s commitment to meaningful community partnership. Sanjgon represents Boralex’s first operational battery energy storage facility in North America, a key component of its long-term growth strategy. A Community Benefit Agreement with the Municipality of Lakeshore will provide $1,000 per MW annually for the life of the project to support local initiatives.
