Toronto, Ontario – May 7, 2025 – The Oneida Energy Storage Project has officially commenced commercial operations, becoming the largest grid-scale battery energy storage facility in operation in Canada and one of the largest globally.
What is the largest battery storage project in Canada?
OHSWEKEN – The governments of Canada and Ontario are working together to build the largest battery storage project in the country. The 250-megawatt (MW) Oneida Energy storage project is being developed in partnership with the Six Nations of the Grand River Development Corporation, Northland Power, NRStor and Aecon Group.
What is the Toronto-Hecate Energy-IESO energy storage procurement phase 1?
The Toronto-Hecate Energy-IESO Energy Storage Procurement Phase 1 is a 13,000kW lithium-ion battery energy storage project located in Toronto, Ontario, Canada. The rated storage capacity of the project is 53,000kWh. The electro-chemical battery storage project uses lithium-ion battery storage technology.
What is the fastest growing energy storage technology in Canada?
BESS is the fastest growing energy storage technology in Canada and is also the dominant storage technology in terms of capacity and number of sites. All but four projects proposed to be commissioned by 2030 are battery storage, with two CAES and two PHS projects also proposed.
Global energy storage capacity was estimated to have reached 36,735MW by the end of 2022 and is forecasted to grow to 353,880MW by 2030. Canada had 138MW of capacity in 2022 and this is expected to rise to 296MW by 2030. Listed below are the five largest energy storage projects by capacity in Canada, according to GlobalData's power database.
Energy storage will allow the storage of baseload generation like nuclear and hydro while also supporting the integration of intermittent resources like wind and solar. The governments of Canada and Ontario are working together to build the largest battery storage project in the country.
Are battery storage projects gaining traction in Canada?
Battery storage projects are gaining traction across Canada, driven by federal incentives and increasing provincial investments. For instance, Alberta's recent 60 MW battery facility and Saskatchewan's utility-scale battery storage installation signal a strong nationwide commitment to supporting renewable energy sources like wind and solar.
