- Northland Power has launched Canada’s largest battery energy storage facility, Oneida, ahead of schedule and under budget.
- The $700 million project has a 20-year contract and supports Ontario’s electricity grid, with help from Indigenous and industry partners.
Northland Power Inc. has commenced commercial operations at the Oneida Energy Storage Project (“Oneida”), delivering the largest battery energy storage facility in Canada. The company completed the project ahead of schedule and under budget.
Oneida, a 250 MW/1,000 MWh facility in Haldimand County, marks Northland’s first operational energy storage project in Canada. By commissioning the project, Northland strengthens its position as a market leader in a critical growth sector of the energy transition.
“Today marks a major milestone for Northland and the Oneida project,” said Christine Healy, President & Chief Executive Officer of Northland. “Oneida represents a pivotal step in our strategy to develop and operate battery storage facilities. As a first-of-its-kind in Canada, it supports grid stability and reliability in Ontario. Delivering this project ahead of schedule and under budget demonstrates our capability to execute large-scale energy projects safely and effectively.”
Northland owns approximately 70 per cent of Oneida. Project partners include Six Nations of the Grand River Development Corporation, NRStor Inc., Aecon Concessions, and Mississaugas of the Credit Business Corporation. At financial close in 2023, the consortium completed the facility at a final cost of approximately $700 million—$100 million below the original estimate.
Ontario’s Independent Electricity System Operator supports the project through a 20-year capacity contract, providing Northland with a stable and long-term revenue stream.
“We’re incredibly proud of what our joint teams have accomplished,” said Michelle Chislett, Executive Vice President of Northland’s Onshore Renewables business. “This milestone reflects the strength of our collaboration with project partners, including our First Nations partners, suppliers, and financiers such as the Canada Infrastructure Bank.”
Following the successful delivery of Oneida, Northland continues to construct major offshore wind projects, including the 1.1 GW Baltic Power project in Poland and the 1.0 GW Hai Long project in Taiwan.
