May 7, 2025 – With 278 lithium-ion units now drawing and storing power from Ontario’s grid, the Oneida Energy Storage Project has officially entered commercial operation, becoming the largest battery energy storage facility in operation in Canada, and among the largest globally.
[pdf] Underground pumped hydro storage utilizes abandoned mines as base assets to enhance the grid and add renewable energy. The facilities take advantage of geologic leverage with more energy storage capability while rebuilding retired mining towns that had once prospered.
[pdf] Jointly developed by National Energy New Energy Research Institute and Ningxia Electric Power Co., Ltd., the project employs hybrid grid-forming technology tailored to western China’s renewable-rich grids, focusing on configuration optimization, low-cost sodium-ion integration, cluster management, and hybrid grid-forming validation.
