June 24, 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.

Located in Haldimand County, Ontario, the 250 MW/ 1,000 MWh facility has been successfully delivered through a collaborative effort between Northland Power Inc., Six Nations of the Grand River Development Corporation (SNGRDC), NRStor Inc., Aecon Concessions, and the Mississaugas of the Credit River Business Corporation as owners of Oneida Energy Storage Limited Partnership. Aecon led the engineering, procurement and construction services for the project alongside Aecon-Six Nations, a general partnership between SNGRDC and Aecon. Northland will oversee operations of the facility.
