Energy Storage in Canada: Recent Developments in a Fast
Energy storage technologies harness and store previously generated energy and then release it as electricity. When certain renewable energy sources, such as solar and wind,
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, May 7, 2025 – The Oneida Energy Storage Project (“Oneida”) has officially entered commercial operations, becoming the largest battery energy storage facility in operations in Canada, and one of the largest globally Follow along for a behind-the-scenes look at building Canada's first battery energy storage facility.
Canada aims to reduce its greenhouse emissions by 45–50% below 2005 levels by 2035. In its 2022 report, ESC noted that the country would need at least 8 to 12GW of energy storage to achieve this goal. Energy storage can continue to grow from provincial governments integrating energy storage into existing regulatory framework.
The electricity produced by wind energy and solar energy can be converted and stored through various means: Many of these technologies can be deployed at multiple scales, but batteries represent the most scalable energy-storage technology.
