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.

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.

The construction of a fish bypass at the Schärding-Neuhaus power plant is currently being planned.
The construction of the power plant and the reservoir area has created unique, new habitats for flora and fauna with the waterbody and the newly created siltation areas. On the Austrian and Bavarian sides, an extensive bird paradise was created between Reichersberg, the Antiesen mouth and Bad Füssing. Rare species of bird, such as night heron, purple heron, little bittern and pintail duck have found a new home here. Compared to the years before the power plant’s construction, many more breeding birds and migratory birds populate the reservoir area today.
