Pumped storage hydropower: provides peak-load supply, harnessing water which is cycled between a lower and upper reservoir by pumps which use surplus energy from the system at times of low demand. When electricity demand is high, water is released back to the lower reservoir through turbines to produce electricity.

However, up to now pumped hydropower energy storages (PHES) can achieve the highest power rating as it can reach up to 5 GW. In contrast, the two closest competing technologies, thermal energy storage and compressed air storage can only reach one tenth of this rating [5]. PHES is the most cost efficient technology per storage …

In this pilot project, the foundations of the wind turbines are used as upper reservoirs of a PHS facility. They are connected to a pumped-storage power station in the valley that can provide up to 16 MW in power. The electrical storage capacity of the power plant is designed for a total of 70 MWh (Max Bögl, 2018).

It involves water that sinks into the soil without being absorbed by plants or evaporation. This precipitate lodges into the earth''s water table. Hydropower converts the kinetic energy in the runoff phase. Because the cycle is kicked off at step1 by the sun, hydro energy is considered a form of solar energy.
