Zhongnengjian Jiangsu Electric Power Construction No.1 Company won the bid for 4.293 billion yuan large project

This is one of the largest single compressed air energy storage power station EPC projects in China so far, with an installed capacity of 3 × 350MW/4200MWh. China Energy Construction Jiangsu Electric Power Construction No.1 Company won the first prize with about 4.293 billion yuan, which is about 67.1 million yuan lower than second Shanghai Electric Power Design Institute (4.360 billion yuan). The price advantage is about 1.5%. The project adopts the technical route of fuel-free compressed air energy storage + medium-temperature heat storage, and the electricity-electricity efficiency of the system is not less than 65%, which represents the highest engineering level of compressed air energy storage in China.

[Project Name] Shenneng Xilingol West Ujimqin Banner Grid Side Compressed Air Energy Storage Project Ground Power Station Engineering EPC

[First Bid Winner and Quotation] China Energy Engineering Group Jiangsu Electric Power Construction First Engineering Co., Ltd.: 4, 293,365,323.17 yuan (4,293,365,300 yuan)

[Basic information of the project] The project is located in Bayanhua Town, West Ujimqin Banner, Xilingol League, Inner Mongolia Autonomous Region. The EPC general contracting mode is adopted, and two contracts are signed separately with the underground gas storage project. The ground power station has a scale of 3 × 350MW/4200MWh, adopts non-fuel compressed air energy storage technology and is equipped with a medium-temperature heat storage system. The charging time is 6.5 hours, the full-power continuous power generation is 4 hours, and the system electricity-electricity efficiency is ≥ 65%. The main facilities include compressors, expansion units, generator sets and supporting electrical, control and auxiliary equipment. The overall construction period is about 27 months. It is planned to be put into operation in December 2027 and completed and accepted in June 2028. The total investment of the project is about 6.8 billion yuan. The second Shanghai Electric Power Design Institute offered 4,360,464,971.25 yuan (4,360,465,000 yuan).
