What is Canadian energy storage?
The blueprint for Canadian energy storage. Located in Haldimand County, Ontario, Oneida Energy Storage is a fully operational, 250 MW/1,000 MWh lithium-ion battery energy storage facility. It represents Canada's largest operational energy storage facility, and is amongst the largest energy storage projects globally.
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.
