Technical FAQs 4

What is the largest battery energy storage facility in Canada?

July 25, 2025 – With 278 lithium-ion battery units—each weighing more than 84,000 lb—now drawing and storing power from Ontario’s electricity grid, the Oneida Energy Storage Project has officially entered commercial operation, becoming the largest battery energy storage facility in operation in Canada, and among the largest globally.

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.

Why is energy storage important in Canada?

A consistent supply of energy storage components will allow Canada to confidently promote its products, technologies, and services in global markets. This, in turn, provides continuity for international investors while also offering certainty to those looking to develop energy storage projects within Canada.

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.
