The project is the region’s first large-scale installation using semi-solid-state lithium iron phosphate batteries. Spanning about 100 mu, it comprises 160 battery cabins and 40 PCS–boost cabins, functioning as a “super power bank” for the Wuhai grid. The station stores excess power during low-load periods and supplies electricity during peak hours, delivering an estimated 189 million kWh of clean power annually.
Project manager stated that the station can complete around 282 full discharge cycles per year, with a maximum single discharge of 800,000 kWh—enough to meet the monthly electricity needs of roughly 4,000 households.
As a key hub in the western Inner Mongolia grid, Wuhai will greatly benefit from the added buffer provided by the storage station. The project will enhance peak shaving, stabilize power supply, and boost renewable energy consumption, serving as a valuable model for integrating generation, grid, load, and storage in a new power system.
