Pumped storage hydropower (PSH) is a type of hydroelectric energy storage. It is a configuration of two water reservoirs at different elevations that can generate power as water moves down from one to the other
Pumped storage plants provide a means of reducing the peak-to-valley difference and increasing the deployment of wind power, solar photovoltaic energy and
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).

450 pumped storage units installed worldwide by Voith. In 1937, Voith developed the first large, single-stage pump turbine, which operated both as a turbine for energy generation and in the reverse direction as a pump. Today, nearly 450 Voith pump turbines have been installed worldwide with a combined output of more than 60 000 megawatts.
