Answer: China
Notes: The world’s largest compressed-air energy storage plant has started operations in Jiangsu province, central China, supporting the country’s green energy transition. The plant has a capacity of 2,400 megawatt-hours and can generate 600 megawatts, enough to meet the annual electricity demand of 600,000 households. China’s energy storage sector has grown rapidly, driven by large-scale renewable energy deployment and a government target of over 180 gigawatts of new capacity by 2027.
