1 July 2010 - Voith Hydro has been awarded a EUR40m ($49m) contract from Voralberger Illwerke to rehabilitate its Rodund II hydropower plant in Austria, which was severely damaged by fire last summer.
Voith Hydro’s scope of supply comprises a reversible pump turbine, an air-cooled motor-generator and its related ancillary equipment.
Furthermore, the plant will see an economical optimization and an upgraded energy management system.
The output in turbine mode will be increased from 276 MW to 295 MW.
The old unit had been in operation since 1976 - only the power house, the spiral case and the draft tube, along with some mechanical auxiliary equipment will remain in place.
“The pump turbine for Rodund II is characterized by its quick start-up, short response times and its high efficiency. It will play an important role for grid stabilization,” explained Dr. Leopold Heninger, CEO of Voith Hydro’s Austrian operating unit.
“We have a special challenge in this project: With the commissioning of the unit by the end of 2011, we have to deal with a very short delivery time. But I am sure we will master this tight schedule very well,” he added.
Utilizing a head of approximately 350 metres, Rodund II generates peak load and regulating electricity.
It is located in the Austrian Montafon area and converts the water volumes of the Kops, Silvretta, Luenersee and Vermuntsee reservoirs
