State Grid Corp. of China says it has completed a pumped hydroelectric storage project consisting of four reversible pump turbine generator units, each with a capacity of 350 MW. It is located near Xiamen, in China’s Fujian province.
Fujian Xiamen Pumped Storage Co., a unit of State Grid Corp. of China, has commissioned the fourth and final section of its Fujian Xiamen Pumped Storage Power Station, marking the full commissioning of the project. The facility is located close to Wangqian and Wufeng villages, near Xiamen, Fujian province.
The first three units were successfully commissioned between October 2023 and March 2024. With all four units online, the construction of the Xiamen Pumped Storage Power Station has been officially completed and has an installed capacity of 1.4 GW.
Construction of the project began in November 2019 and required a total investment of CNY8.664 billion ($1.19 billion). It involves the installation of four reversible pump turbine generator units, each with a capacity of 350 MW. The station is connected to Fujian’s power grid via two 500 kV transmission lines.
The Xiamen Pumped Storage Power Station will pump water to a high-altitude reservoir during off-peak periods and generate electricity during peak periods, effectively balancing peak and off-peak demand from the power grid. The facility is designed to absorb 3,127 TWh of electricity from the valley annually and provide 2,345 TWh of peak electricity.
East China Survey and Design Institute designed the factory and China Hydropower Engineering Corp. acted as technical contractor.
The Xiamen Pumped Storage Power Station will regulate the Fujian power grid on a daily basis by handling peak shearing, valley filling, frequency control, phase modulation and emergency standby. This will alleviate peak regulatory pressure and increase the province’s ability to integrate more renewable energy.
Located on the southeastern coast of China, Fujian Province has favorable geographical conditions characterized by mountainous terrain and abundant rainfall, making it an ideal location for pumped storage development. Since 2015, developers in Fujian have built or begun construction of more than 10 gigawatt pumped hydro plants, significantly contributing to the development of green energy and the stability of the power system.
