Customer ServiceIntroduction Pumped storage power station is a kind of hydropower station with energy storage function. It uses surplus electricity during periods of low power demand to pump water from a lower reservoir to a higher one.
The same can be applied to solar generation: the pumped storage power station can contribute to constant electricity production at night time when there is no sunshine to run a solar power plant. The flexibility extends not just to the turbine and tank sizes, but also to the depth the system is installed at.
Pumped storage is by far the largest-capacity form of grid energy storage available, and, as of 2020, accounts for around 95% of all active storage installations worldwide, with a total installed throughput capacity of over 181 GW and a total installed storage capacity of over 1.6 TWh.
During the “Twelfth Five-Year Plan” and “Thirteenth Five-Year Plan” periods, to adapt to the rapid development of new energy and UHV power grids, pumped storage power stations such as Fengning in Hebei Province and Jixi in Anhui Province ushered in a new peak.
Greater levels of intermittent renewables on energy systems around the world will make pumped storage all the more vital in helping to balance grids. Their mountainous locations also make pumped storage stations some of the most dramatic and interesting monuments in energy.
The geographical location selection for pumped storage power stations should adhere to the principle of decentralized distribution, focusing on areas near the grid load centers and regions with a high concentration of new energy sources.
