Gunggl Run-of-River Power Plant

VERBUND’s Gunggl power plant is a run-of-river power plant in the municipality of Gnadenwald in Tyrol.

Technical Description 

The Gunggl power plant was constructed from 1986 to 1990. Following a few test runs, small rips in the penstock became evident, which were caused by the high energy flow of the water. In order to prevent this, a pressure reducing valve to dissipate energy was built in. A Francis spiral turbine and a volute casing pump together generate on average a yearly output of around 7 GWh.
