LAKESHORE, Ontario — January 6, 2026 — Leads & Copy — Boralex inc. (TSX: BLX), in partnership with Walpole Island First Nation, has announced the commercial commissioning of Sanjgon Battery Energy Storage, Boralex’s first energy storage facility in operation in North America.
Located in the Municipality of Lakeshore, Ontario, the 80 MW / 320 MWh facility marks a milestone in Boralex’s 2030 Strategy, as well as its expansion into large-scale storage solutions.
The Tilbury Battery Storage Project was renamed Sanjgon Battery Energy Storage through a joint approach with Walpole Island First Nation. The term “Sanjgon,” derived from the Nishnaabemwin language, evokes the traditional storage practices used by the Nation’s families.
Developed in close collaboration with Walpole Island First Nation, the facility reflects Boralex’s commitment to long-term partnerships with Indigenous and local communities. 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.
Boralex will reach 380 MW of installed storage capacity in Canada, making it the largest battery storage operator in the country, with Sanjgon now operational and the Hagersville Battery Energy Storage Park scheduled for commissioning in the coming weeks. Additional storage projects are under development, including the Oxford project, which is expected to begin construction shortly.
Sanjgon is Boralex’s first operational energy storage facility in North America.
The facility was developed in collaboration with Walpole Island First Nation and is supported by the Municipality of Lakeshore through a Community Benefit Agreement.
The facility has an installed capacity of 80 MW / 320 MWh, enabling four hours of continuous full-power delivery to the grid, and has 89 Tesla Megapack 2XL units.
Sanjgon was selected through the Independent Electricity System Operator’s (IESO) Expedited Long-Term Request for Proposals and directly supports Ontario’s Resource Adequacy Framework.
Leela Thomas, Chief of Walpole Island First Nation, stated the Sanjgon Battery Energy Storage facility marks a significant step toward a cleaner, more reliable energy future and that Walpole Island First Nation values this partnership with Boralex.
Lesley Gallinger, President and CEO, Independent Electricity System Operator, said the Sanjgon Battery Energy Storage project is an example of how they are working with Indigenous communities, municipalities, private industry and government to build out the province’s electricity system and support Ontario’s economic growth.
Trevor Jones, MPP for Chatham-Kent-Leamington and Minister of Agriculture, Food and Agribusiness, stated this project strengthens our grid, supports economic growth, and reflects the collaborative spirit that drives progress in our region.
Tracey Bailey, Mayor, Municipality of Lakeshore, said their communities are proud to play a role in advancing Ontario’s clean energy future.
Patrick Decostre, President and CEO of Boralex, stated it’s a concrete step forward in delivering on their 2030 Strategy and creating durable value for their shareholders, expanding their presence in storage, and reinforcing their commitment to innovation and community partnerships.
