ENGINEERINGNET.EU -- E.ON reports it has received permission from the German authorities to expand the Waldeck 2 pumped storage power station in Edertal/Hemfurth.
The permit mainly concerns the construction of another underground power station cavern with a 300 megawatts pump turbine.
The envisaged plant will for the first time feature an asynchronous generator on a scale unprecedented in a hydroelectric station.
This generator will allow a very flexible plant operation. The project entails investments amounting to around 250 million euros. A final investment decision is to be taken in 2012.
Pumped storage power stations can efficiently store surplus energy and are thus an excellent partner for integrating intermittent renewable energy supply.
E.ON is investing billions of euros in the further development of renewables and the construction of flexible pumped storage power stations.
Only last week the company announced the erection of several offshore wind farms in German, Swedish and UK sea areas.
