On September 23, Shandong Feicheng Salt Cave Advanced Compressed Air Energy Storage Peak-shaving Power Station made significant progress. The first phase of the 10MW demonstration power station passed the grid connection acceptance and was officially connected to the grid for power generation. This marked the world’s first salt cave advanced compressed air power station. The energy storage power station has entered a state of formal commercial operation. The Feicheng Salt Cave Compressed Air Energy Storage Power Station technology was developed by the Institute of Engineering Thermophysics, Chinese Academy of Sciences. This technology has the advantages of large scale, low cost, long life, and environmental friendliness. It is one of the most promising large-scale energy storage technologies.
该项目利用肥城地下丰富的盐穴资源。当电网负荷较低时，空气经压缩机压缩后进入盐穴储存。当电网负荷达到峰值时，释放高压空气驱动膨胀机做功，带动发电机发电。实现电力系统调峰、调相、旋转备用、应急响应、黑启动等功能。该项目正式并网发电。这是我国盐穴压缩空气储能领域的一个重要里程碑，将我国压缩空气储能技术提升到一个新的水平，具有划时代的意义。
项目实施和试运行过程中，得到了泰安市委市政府、肥城市委市政府、肥城市经济开发区、泰安能源局、国网泰安的大力支持供电公司和肥城供电公司为项目的正式商业运营提供了条件。强有力的保证。
该项目负责人表示，肥城压缩空气储能国家示范电站正式投运，将有力推动电力系统运行管理发生重大变革，有力支持能源革命，提高发电比重可再生能源发电，助力“碳中和”目标的实现，带动相关产业发展，服务肥城经济发展。
