Perach Run-of-River Plant

VERBUND's power plant at Perach is a run-of-river plant situated on the river Inn above the Alz estuary in Bavaria.

Technical Description 

The Perach power plant was built from 1974 to 1977. It is the first pier power station on the river Inn, a structure, which was developed on the Drau and which is characterised by its lower construction costs and better removal of floating refuse. Furthermore, Perach was the first power plant to be conceived for fully-automated operation and to be monitored by the Töging control room from the start. It is made up of four weir openings and three turbine piers. Every turbine pier is equipped with a Kaplan turbine with horizontal shafts and a fitted generator. On average, the Perach power plant generates around 128 GWh of electricity per year. Furthermore, a fish ladder is currently also being planned.
