North America is making strides toward a cleaner, more reliable, and cost-effective electricity grid. At the centre of this movement is the Oneida Battery Energy Storage System (BESS) — a landmark project that is transforming the Canadian energy landscape. With one of the largest energy storage capacities in the country, the Oneida BESS strengthens the grid, supports economic growth, and helps Ontario reduce its environmental footprint.
As a trusted partner in energy infrastructure projects and as a leader in custom control panels and engineering services, Keltour was proud to support the Oneida Battery Energy Storage System in Ontario. Our work included a range of products, engineering expertise, and integration services that contributed to its world-class quality and functionality.
What Is a Battery Energy Storage System?
Battery energy storage systems are becoming an essential part of modern energy infrastructure. They provide the ability to store excess electricity from any source, including baseload power from nuclear and hydro, or variable sources like wind and solar. These storage systems can then release it back into the grid when demand is high.
The Oneida Battery Energy Storage System demonstrates the scale and potential of this technology:
- Capacity: 250 MW/1,000 MWh of storage
- Scale: 278 lithium-ion battery containers, storing enough energy to power about 410,000 homes
- Impact: Nearly doubles Ontario’s clean electricity storage capacity from 225 MW to 475 MW
- Environmental Benefit: Reduces greenhouse gas emissions by up to 4.1 million tonnes annually—the equivalent of removing 40,000 cars from the road
With its ability to stabilize Ontario’s clean electricity grid, the Oneida project is one of the most advanced battery energy storage systems in Canada and a major step toward a low-carbon future.
