Pumped storage power station construction started

A mega pumped storage power station started construction on Thursday at an average altitude of 4,300 meters above sea level, which is the highest one in the world and the largest one of its kind in China's Sichuan Province. From underground caverns in Austria to record-speed builds in China and long-duration storage studies in the US, pumped storage hydropower is re-emerging as the backbone of renewable integration. A wave of projects in 2025 shows how engineers are adapting old principles to new system needs. The. (ECNS) -- As a project of the Yalong wind and solar power base, the world's highest-altitude pumped--storage power station on Yalong River, started construction in Daofu County, Tibetan Autonomous Prefecture of Garze, Sichuan Province, the Science and Technology Daily has reported. Located at an. (Yicai) Sept. 10 -- East China's largest pumped storage power station, with a total investment of CNY12.5 billion (USD1.8 billion), is about to begin construction. Located in Jiande, Zhejiang province, the station will have an installed capacity of 2.4 gigawatts, the project developer GCL Energy. Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of hydroelectric energy storage used by electric power systems for load balancing. A PSH system stores energy in the form of gravitational potential energy of water, pumped from a lower elevation. Recently, following instruction from staff of the State Grid Hangzhou Power Supply Company, the first-phase of the construction power supply project of Zhejiang Tonglu Pumped Storage Power Station was completed and energized, providing power guarantee for the main construction of the pumped storage.
