Canada's Oneida Energy Storage Project Launches Ahead of Schedule and Under Budget in Ontario
The Oneida Energy Storage project in Haldimand County, Ontario, is now operational, exceeding timelines and budget constraints. The facility, with a capacity of 250 megawatts and 1,000 megawatt-hours, is co-owned by Six Nations of the Grand River Development Corporation (SNGRDC), Northland Power, NRStor Inc., Aecon Concessions, and the Mississaugas of the Credit Business Corporation, through Oneida Energy Storage Limited Partnership.
Initially budgeted at $800 million, the project was completed for $700 million. It features 278 lithium-ion battery units and will generate income through a 20-year contract with Ontario's Independent Electricity System Operator (IESO), alongside revenues from energy sales and ancillary services.
The project enhances Ontario's energy storage capacity from 225 to 475 MW and aims to reduce greenhouse gas emissions by 1.2 to 4.1 megatonnes over its lifespan. The initiative employed over 180 workers, including many Indigenous individuals, and received funding from Natural Resources Canada and the Canada Investment Bank.
