E.ON Wasserkraft has awarded Voith Siemens Hydro’s German unit a US$28M contract to supply equipment for the modernisation of the Waldeck I pumped storage plant.

The overall technical concept – from structural to electro-mechanical design – was elaborated by Voith Siemens Hydro in close cooperation with Bilfinger Berger. This led to finding the most efficient solution during the pre-bid phase, when Voith Siemens Hydro and Bilfinger Berger considered all aspects of interdependency of hydraulic design, electromechanical concept and architectural aspects.

While Bilfinger Berger will execute the civil works for the new complex, built additionally to the existing station of Waldeck I, Voith Siemens Hydro will be responsible for the supply of a new reversible pump turbine with 74MW turbine output, motor-generator, shut-off valves, start-up converter, transformer and process control.

E.ON Wasserkraft will invest a total of US$60M in the hydro power project, which is located in Germany’s federal state of Hesse on the Edersee lake.
