The Oneida Energy Storage Project has officially commenced commercial operations. The project was completed ahead of schedule and under budget and is the largest battery energy storage facility in operation in Canada.
“Today marks a major milestone for Northland and the Oneida project,” said Christine Healy, President & Chief Executive Officer of Northland Power Inc. “Oneida represents a pivotal step in our strategy to develop and operate battery storage facilities. A first-of-its-kind in Canada, this facility supports grid stability and reliability in Ontario. Delivering this project ahead of schedule and under budget is a clear demonstration of Northland’s capability to execute large-scale energy projects safely and effectively.”
Located in Haldimand County, Ont., Oneida is a 250 MW / 1,000 MWh battery storage facility. It is Northland’s first operational energy storage project in Canada. Northland owns approximately 70 per cent of Oneida, with the remaining ownership held by Six Nations of the Grand River Development Corporation, NRStor Inc., Aecon Concessions and Mississaugas of the Credit Business Corporation. The project was completed with a final cost of approximately $700 million, compared to the initial $800 million estimate at financial close in 2023. Oneida is backed by a 20-year capacity contract with Ontario’s Independent Electricity System Operator, providing stable, long-term revenue.
“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 strong collaboration among our project partners, including our First Nations partners, suppliers, and financiers, including the Canada Infrastructure Bank.”
With the completion of Oneida, Northland remains focused on the successful and safe delivery of its construction projects, including the 1.1 GW Baltic Power offshore wind project in Poland and the 1.0 GW Hai Long offshore wind project in Taiwan.
Headquartered in Toronto, Ont., with global offices in seven countries, Northland owns or has an economic interest in 3.5 GW of gross operating generating capacity, 2.2 GW under construction and a significant inventory of early to mid-stage development opportunities encompassing approximately 10 GW of potential capacity.
Northland has been publicly traded since 1997. Northland’s CEO was recently featured in Environment Journal’s Market Watch column. To read the article, click here.
