Waldeck Pumped Storage Station is one of the largest pumped storage power stations in Germany. It is located in the Waldeck-Frankenberg district in the municipality Edertal near the town Waldeck in the northern part of the state Hesse and is owned by German electric utility E.ON.
The power station consists of two parts with a common lower reservoir.
Waldeck I
Waldeck I was commissioned in 1931 and has currently an installed capacity of 143 MW. Water is stored in the Waldeck I Upper Reservoir which has a volume of 0.7 mn m³.Waldeck II
Waldeck II was commissioned in 1974 and has currently an installed capacity of 480 MW. Water is stored in the Waldeck II Upper Reservoir which has a volume of 4.4 mn m³. Waldeck II is built as an underground power station, its machinery is located in a large cavern.It was planned to extend Waldeck II with an additional turbine of 300 MW. This project is postponed at some indefinite future date because new pumped storage stations are not profitable in Germany.
