At 7:56 am on June 30th, with the issuance of power generation instructions, the last unit of Changlongshan Pumping Power Station, a provincial key project located in Tianwaoping Town, Anji County, successfully generated electricity. At this point, all the 6 machine groups of the power station have been put into operation.

The total investment of Changlong Mountain Pumping Power Power Station was 10.683 billion yuan. A total of 6 generator sets were designed and installed. The total installed capacity was 2.1 million kilowatts, and the average annual power generation volume was 2.435 billion kWh. The power station hub is mainly composed of buildings such as the upper reservoir, the lower reservoir, the water recusion system, the underground plant, and the 500 -kilovolt ground switch station. The power station belongs to the "high water head, high speed, large capacity" daily regulation of pure pumping power storage power stations. It is the first complete pumping storage project led by China Three Gorges Group's investment, construction, and operation.

Changlong Mountain pumping water storage power station is located in the East China Power Grid Loading Center. It mainly undertakes the double peak adjustment function of the entire East China Power Grid peak and valley. It is the largest "charging treasure" in East China Power Grid. The power station is close to the construction of the Tianhura Ping pumping power station. It is located near the East China Power Grid load center and the 500 -kilovolt main network. The grid conditions are superior. Electric energy can be easily transported to large cities such as Shanghai, Nanjing, Hangzhou, etc. The peak -cutting effect of pumping power stations. Since the first unit was put into production and power generation at the end of June 2021, the construction and operation of Changlongshan pumping power storage power stations were organized in an orderly connection, and 6 units were put into operation within one year. As of now, the power station has sent a total of over 1.5 billion degrees of clean electricity, and the pumping water consumes over 2 billion kWh.

The 15th Party Congress of the Provincial Party proposed that the carbon peak plan was implemented to build a national clean energy demonstration province at a high level. As the largest pumping storage power station in East China, after all the pumping power stations in Changlongshan Mountain can save 210,000 tons of margin coal for East China Power Grid each year, reduce carbon dioxide by about 420,000 tons and about 2800 tons of sulfur dioxide each year, which will further optimize East China Regional power structure, improve the operation conditions of East China Power Grid, and solidly promote carbon peaks and carbon neutrality.
