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).

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. The method stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation. Low-cost surplus off-peak electric power is typically used to run the …

Pumped hydro storage uses two water reservoirs which are separated vertically. In times of excess electricity, often off peak hours, water is pumped from the lower reservoir to the upper reservoir. When required, the water flow is reversed and guided through turbines to generate electricity. | Tue, 11/08/2016.
