Recently, the 300MW advanced compressed air energy storage demonstration power station in Zhangjiakou, which is jointly operated by China Storage Energy, the Institute of Engineering Thermophysics of the Chinese Academy of Sciences and the East China Survey, Design and Research Institute of Power Construction Corporation of China Group, successfully passed the review of experts in the feasibility study report. This marks the first 300 megawatt compressed air energy storage demonstration power station in China's national renewable energy demonstration zone, achieving important milestone results.

The construction scale of this project is 300 MW/1200 MWh, using artificial chambers as gas storage methods. One 300 MW advanced compressed air energy storage demonstration system, one 220 kV substation, and supporting facilities will be constructed.

The review meeting was presided over by Zhao Quansheng, chief engineer of the General Institute of Hydropower and Water Resources Planning and Design, and the expert group was composed of Zhang Zongliang, academician of the Chinese Academy of Engineering, and more than 20 experts in various fields. During the review, the expert group listened to the feasibility study report of the project and the report on the underground engineering situation. After careful questioning and discussion, the experts unanimously agreed that the project passed the feasibility review.

After the project is completed and put into operation, it is expected to provide an additional 400 million kilowatt hours of electricity annually for the province and surrounding areas, saving 8.44 tons of standard coal, which will significantly enhance the regulatory capacity of the national renewable energy demonstration zone's power grid and meet the development needs of safe and stable operation of the new power system and power supply guarantee.
