Goldisthal Pumped Storage Station

The Goldisthal Pumped Storage Station is a pumped-storage power station in the Thüringer Mountains at the upper run of the river Schwarza in Goldisthal, Germany. It was constructed between 1997 and 2004. It has an installed capacity of 1,060 megawatts , the largest hydroelectric power plant in Germany and one of largest in Europe.
The upper reservoir is located at an altitude of 880 m . It has an active capacity of 12 millions m³ and a surface area of 55 hectares. In order to create this basin, the mountain summit was cleared away. This stored quantity of water is enough for eight hours of operation. This corresponds to a maximally storable electric power quantity of 8.5 GWh with the existing height difference between storage basins and turbines. Two 800 m long penstocks, inclined at approximately 25 degrees serve as a conduit for water transfer. The lower reservoir has a capacity of 18.9 million cubic metres . The power station contains four 265 MW Francis pump turbines.
