Customer ServiceThe pumped storage power station (PSPS) is a special power source that has flexible operation modes and multiple functions.

Customer ServiceTheir special feature: They are an energy store and a hydroelectric power plant in one. If there is a surplus of power in the grid, the pumped storage power station switches to pumping mode – an electric motor drives the pump turbines, which pumps water from a lower reservoir to a higher storage basin.
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.
1. The Pumped Storage System and Its Constituent Elements Pumped storage hydro is a mature energy storage method. It uses the characteristics of the gravitational potential energy of water for easy energy storage, with a large energy storage scale, fast adjustment speed, flexible operation and high efficiency .
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.
In order to ensure the security and stability of the power system, many countries have built a large number of pumped storage power plants to regulate energy flexibly, efficiently and cleanly. In many developed countries, the proportion of pumped storage power plants in the power system exceeds 10%.
One of the long-established means of storing energy and using it to generate electricity when needed is through pumped hydropower storage. With upper and lower reservoirs of water, and turbines in between, these facilities act a bit like rechargeable batteries.
