VERBUND's power plant of Gstatterboden is a run-of-river plant situated on the river Enns and located in the municipality of Wenig im Gesäuse in Styria.
The Gstatterboden power plant was built between 1953 and 1955 and is located on the Gstatterboden weir system of the Hieflau power plant. The Wag reservoir was added between 1960 and 1963. A second headrace tunnel was added to the power plant in 2010. The power plant generates 6.9 GWh of electricity from 100% hydropower and supplies the surrounding homes with environmentally friendly energy.
The Gstatterboden weir system was equipped with a fish bypass in 2010. The approximately 270 metre-long fish bypass overcomes a height difference of 10.9 metres with a vertical slot passage and a subsequent near-natural bypass channel. The dimensions of the fish bypass were adapted to the size-determining species, the Danube salmon.
