Gansu Energy Storage: Powering China's New Energy Future

State Grid Gansu Electric Power Company is pioneering energy storage development in China's major new energy province. With over 60% installed new energy capacity, Gansu leverages storage to ensure grid security and support the 'dual carbon' goals. The province ranks fifth nationally in energy storage capacity, achieving over 100% growth. Mainstream LFP batteries dominate, while diverse demonstrations explore vanadium flow, compressed air, and gravity storage. Key projects like the 600MW Huaneng Longdong station and 300MW Zhangye Linze station showcase rapid deployment and efficiency. The world's first 300MW non-supplementary combustion compressed air station in Jiuquan offers low-cost, long-duration storage. Core technology includes a provincial-level coordination control system enabling centralized dispatch, millisecond-level automated peak shaving, and 'one station, one strategy' optimization. This system integrates source-grid-load-storage collaboration, enhancing consumption of renewables and grid resilience. Gansu's practices provide a model for energy storage integration, addressing challenges like cost reduction and technology diversification, while advancing toward a new-type power system.
