A semi-solid-state lithium battery energy storage project in Wuhai, Inner Mongolia, successfully connected to the grid, generating 189 million kilowatt-hours annually
At 21:59 on November 30, 2025, with a clear command from shift supervisor Liu Jiahao, the Wuhai 200,000 kW/800,000 kW semi-solid-state energy storage power station—China's largest grid-side independent new energy storage project using semi-solid-state lithium iron phosphate batteries—successfully connected to the grid. Invested and constructed by China Green Development Investment Group Co., Ltd., the project covers approximately 100 acres and has a total investment of 600 million yuan. It is the first large-scale energy storage project in Inner Mongolia Autonomous Region to adopt semi-solid-state lithium iron phosphate battery technology. This "super power bank" features 160 energy storage battery compartments and 40 integrated converter and booster compartments. Through peak-shaving regulation, it can deliver 189 million kilowatt-hours of clean electricity to the grid annually. Based on typical household electricity standards, a single maximum discharge of 800,000 kilow...
