Built to store, powered by partnership – Oneida sets the standard for grid-scale battery energy storage
AI Article Summary

The Oneida Energy Storage Project in Ontario has commenced operations as the largest battery energy storage facility in Canada, achieved through a partnership between Northland Power Inc. and several other entities. The 250-MW/1000-MWh facility came online two months early and under budget, despite rising costs of lithium-ion batteries. This project serves as a model for future energy storage initiatives, providing increased grid reliability and reducing emissions significantly. Developments were supported by strong partnerships with Indigenous communities and organizational collaborations, illustrating the potential for large-scale sustainable energy solutions.
