Gerlos Reservoir Power Plant

VERBUND’s Gerlos power plant is a reservoir power plant and is situated at the southern end of the locality of Rohrberg in the Ziller Valley, Tyrol.

The Gerlos power plant is located at the southern end of the village of Rohrberg in the Zillertal on the steep slope of the Rohrerberg and was built in several stages between 1939 and 2007. In the second expansion stage from 2004 to 2007, the plant was extended with the Gerlos II power house, which houses a new machine set with an output of 135,000 kW. This increased the bottleneck capacity of the Gerlos power plant from 65,200 kW to 200,200 kW.

Ecology & environmental protection

Sustainable River Management is a project under the scientific direction of the University of Natural Resources and Life Sciences and e3 consult, which VERBUND Hydro Power GmbH co-financed as one of the consortium partners. 
Achieving the environmental targets of the EU Water Framework Directive is just as essential for national climate targets as it is for the implementation of the EU’s energy and climate packages. Over many years of cooperation between science, power generation and the authorities, the understanding between the interest groups has been deepened and meaningful, efficient solutions for the implementation discussed. A method has been developed for comparing the ecological effects or the ecological improvement potential of individual surge-absorbing measures with the corresponding system-relevant as well as economic and business effects. Further information about the SuREmMa project  can be found here.
Responsible treatment of the environment
The power plant has an annual generation of 316 GWh. 

Gmünd dam: The final structure was erected between 1943 and 1945 as a 37 metre-high vaulted wall. In the years that followed, the retaining wall was frequently renovated and extended, and a new slide chamber and tipping basin were erected. At the same time, the water level of the Gmünd storage facility was increased by 1 metre to 1,191.25 metres. The useful capacity now amounts to 0.85 million m3.

Turbines and generators: In the two machine halls of the storage power plant there are five machine sets (Pelton turbines) with a total bottleneck capacity of 200 MW.
