The World’s First 300MW A-CAES Project Has Connected to The Grid

4月30日上午11时18分，具有完全自主知识产权的山东肥城国际首套300MW/1800MWh先进压缩空气储能国家示范电站首次并网发电一次成功。该电站采用中国科学院工程热物理研究所自主研发的先进压缩空气储能技术，中储国能（北京）技术有限公司作为投资建设单位，中国电建集团核电工程有限公司作为施工方，是目前国际上规模最大、效率最高、性能最优、成本最低的新型压缩空气储能电站。

In the morning of April 30th at 11:18, the world’s first 300MW/1800MWh advanced compressed air energy storage (CAES) national demonstration power station with complete independent intellectual property rights in Feicheng city, Shandong Province, has successfully achieved its first grid connection and power generation. The power station utilizes advanced CAES technology independently developed by the Institute of Engineering Thermophysics， Chinese Academy of Sciences. Zhongchu Guoneng (Beijing) Technology Co., Ltd. Invested the project and led to construct it. Power China Nuclear Engineering Company Limited. is the construction party.It is currently the largest-scale, highest-efficiency, best-performing, and lowest-unit cost new type of CAES power station in the world.

研发团队突破了300MW级压缩空气储能系统全套核心关键技术，攻克了多级宽负荷压缩机和多级高负荷透平膨胀机技术、高效超临界蓄热换热器技术、系统全工况优化设计与集成控制技术，创造性研制出300MW多级高负荷透平膨胀机、多级宽负荷组合式压缩机和高效紧凑式蓄热换热器等核心装备。系统单位成本较100MW系统下降30%以上，系统装备自主化率达100%，实现了完全自主可控。

The R&D team has made breakthroughs in key technologies for the 300MW CAES system, overcoming technical challenges such as multi-stage wide-load compressor, multi-stage high-load expander, high-efficiency supercritical heat storage  and heat exchange unit, and optimized design at full operation condition and integration of the whole system They have innovatively developed core components of the 300MW system including a multi-stage high-load expander, a multi-stage wide-load combination compressor, and a high-efficiency compact heat storage and exchange unit.   Compared to the 100MW CAES system, the unit cost of 300 MW CAES system has decreased by more than 30%, and system has 100% independent intellectual property rights, all core technologies areindependent and controllable.

该电站建设规模为300MW/1800MWh，工程总投资14.96亿元，系统额定设计效率 72.1%。可实现连续放电6小时，年发电约6亿度，在用电高峰为约20-30万户居民提供电力保障，每年可节约标准煤约18.9万吨，减少二氧化碳排放约49万吨。

The power station has a capacity of 300MW/1800MWh, with a total investment of 1.496 billion yuan. Its rated design efficiency is 72.1%. It can achieve continuous discharge for six hours, generating approximately 600 million kWh per year. This provides power support for about 200,000 to 300,000 households during peak electricity demand, saves about 189,000 tons of standard coal annually, and reduces carbon dioxide emissions by about 490,000 tons.

该电站利用山东省肥城市丰富的地下盐穴资源储气，以空气为介质在电网侧实现大规模电力储能，能够为电网提供调峰、调频、调相、备用、黑启动等电力调控功能，有效支撑电力系统平稳、高效运行。

The power station in Feicheng City, Shandong Province, utilizes the abundant underground salt cavern resources for gas storage. Using air as the storage medium, it achieves large-scale power storage on the grid side. The station provides various functions such as peak shaving, frequency regulation, phase adjustment, standby power, and black start capabilities, effectively supporting the stable and efficient operation of the power system.

肥城300MW先进压缩空气储能项目在山东省各级政府、发改委、能源局的支持下，在国网山东公司“清风暖阳”专项并网服务帮助下，顺利并网发电，是压缩空气储能领域重要里程碑，可有效推动压缩空气储能技术及产业快速发展，进一步巩固了我国在压缩空气储能领域的国际领先地位，为该技术的大规模推广应用打下了坚实基础。

The 300MW advanced CAES power station in Feicheng City has successfully achieved its first grid connection and power generation with support from governments at all levels in Shandong Province, Shandong Development and Reform Commission, the Energy Administration of Shandong Province, and the special grid connection service assistance of 'Qingfeng Nuanyang' by the State Grid Shandong Electric Power Company. This marks an important milestone in the field of CAES, effectively promoting the rapid development of CAES technology and industry. It also consolidates China's international leadership in the CAES field and lays a solid foundation for the large-scale promotion and application of the technology.
