Increased production
The project Obervellach II will replace the existing facilities at the locations in Obervellach and Mallnitz. The aim is to optimise the production of traction current: The planned systems will increase production by more than 30 percent.

Improving the ecological situation
Planning and constructing the new hydroelectric power plant Obervellach II offers many advantages for the environment. Despite the increase in the self-generation of traction current, the overall ecological situation will also be improved vastly. Minimum flow rates are achieved in line with state-of-the-art technology. The lives of residents in the vicinity of existing power plants will be significantly improved by relocating the power plant to the existing industrial site thus reducing operational noise and vibrations. A legally valid UVP notification has been available since February 2016.
Das Kraftwerk im Überblick
Das Wasser aus dem Mallnitz-, Dösen- und Kaponigbach wird über ein 5.000 Meter langes Stollensystem zu einem gigantischen Speicherstollen geleitet. Der Speicherstollen ist 13 Meter hoch, 15 Meter breit, 580 Meter lang und kann bis zu 60 Millionen Liter Wasser speichern. Von dort wird das Wasser je nach Bedarf durch die Druckrohrleitung ins 488 Meter tiefer liegende Krafthaus abgelassen. Zwei Pelton Laufräder mit einer Größe von 2,3 Metern treiben dort die beiden Generatoren an.
