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.
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.
Toronto Hydro recently installed a battery energy storage system (BESS) with Renewable Energy Systems Canada and support from the Province of Ontario's Smart Grid Funds. The Bulwer BESS project is a 2 MW/2 MWh BESS located at the Bulwer Municipal Station (MS), a decommissioned 4.16kV Toronto Hydro electrical substation, located in downtown Toronto.
Why is energy storage important in Ontario?
Ontario's electricity grid is more than 90 per cent emissions-free. 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.
How big is Canada's energy storage capacity?
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.
