Recently, the No. 3 unit of the Xinyuan Jiangsu Jurong Pumped Storage Power Station, contracted by Gezhouba Second Company, a subsidiary of Power Construction Corporation of China, was connected to the grid, marking the completion of the first three units of the power station.
The main project of the State Grid Xinyuan Jiangsu Jurong Pumped Storage Power Station started construction in March 2017, with plans to install six 225,000-kilowatt reversible hydraulic turbine generator units, with a total installed capacity of 1.35 million kilowatts.

This power station is a major project promoting the construction of ultra-high voltage power grids and serving clean energy and socio-economic development. It has created three 'world's firsts': the world's highest pumped storage power station dam, the world's highest pumped storage asphalt concrete panel rockfill dam, and the world's largest pumped storage reservoir filling project.
The elevation difference between the upper and lower reservoirs of the power station is about 144 meters, equivalent to the height of the Great Pyramid of Giza; the upper reservoir dam is 182.3 meters high, and the upper reservoir has a water storage capacity of 17.07 million cubic meters, equivalent to 1.2 times the water storage capacity of West Lake. The construction of the power station has created many industry records, providing a demonstration and reference for the construction of pumped storage power stations in high-load plain areas in China.
Gezhouba Second Company of Power Construction Corporation of China, as the general contractor, is responsible for the construction of the upper reservoir, lower reservoir, water conveyance system, underground powerhouse, switch station, and on-site roads. During the construction process, "asphalt concrete panel + geomembrane waterproof layer" was used for the first time.

In addition to the three units already in operation, the remaining three units of the Jurong Pumped Storage Power Station are currently being installed and commissioned, and are scheduled to be connected to the State Grid by the end of this year. At that time, the power station will be able to generate 1.35 billion kilowatt-hours of green electricity annually, enough to meet the annual electricity consumption of about 530,000 households, saving about 140,000 tons of standard coal and reducing carbon dioxide emissions by about 349,000 tons annually. This will play a significant role in alleviating Jiangsu Province's peak-load pressure, promoting new energy consumption, and serving the national Yangtze River Delta integration development strategy.
