The second phase of project in Changzhou, Jiangsu province, undertaken by China Huaneng Group Co., Ltd., entails building two 350-megawatt non-supplementary fired compressed air energy storage units, with a total volume of 1.2 million cubic meters, making it the largest in unit capacity, storage volume and efficiency.
Once completed, the project will store 2.8 million kilowatt-hours per charge, saving on 270,000 tons of standard coal annually and reducing carbon dioxide emissions by 520,000 tons.
To date, the project has overcome key technological bottlenecks, achieving 100 percent localization of air turbines and compressors. It will significantly enhance the regional energy structure, strengthen local grid regulation capabilities, improve renewable energy integration and support efficient utilization of clean energy.
