高寒地区首个！吉林省洮南市350兆瓦压缩空气储能绿色电站一体化示范项目开工

Core Viewpoint - The commencement of the 350 MW compressed air energy storage green power station in Tiaonan City, Jilin Province, marks a significant step towards energy security and green low-carbon transformation in China [1][5]. Group 1: Project Overview - The project is the first compressed air energy storage green power station in high-cold regions of China and the first of its kind in Jilin Province [1]. - It utilizes a self-developed "China Energy Construction Compressed Air Energy Storage System Solution" with an initial investment of approximately 4.3 billion yuan [3]. - The project will feature a 350 MW compressed air energy storage unit with a storage capacity of 1,400 MWh, capable of storing energy for 7 hours and releasing it for 4 hours, with an expected annual operation of 330 days and a maximum annual power generation of about 462 million kWh [3]. Group 2: Technological and Environmental Aspects - The project employs an efficient and environmentally friendly non-reburning compressed air energy storage technology, including the construction of artificial caverns as gas storage facilities [3]. - It will be complemented by wind power and deep geothermal energy systems, with its single-unit capacity, storage scale, and conversion efficiency being at the world-leading level [3]. Group 3: Strategic Importance - The project is a landmark achievement in supporting national energy security strategies and promoting green low-carbon development in Jilin Province and Baicheng City [5]. - Its implementation is expected to significantly enhance Tiaonan City's regulation capacity in the new power system and improve energy security levels, while also driving the development of the industrial chain [5]. - As a large-scale compressed air energy storage demonstration project, it will greatly improve the absorption capacity of renewable energy in western Jilin Province and enhance the flexibility and stability of the provincial power grid [7].
