The Greifenstein power plant was built between 1981 and 1985. Nine horizontal Kaplan bulb turbines generate an annual average of approx. 1,753 GWh of electricity. The Greifenstein fish bypass was opened in 2018 and, as a natural bypass stream, offers freedom from barriers and a habitat for fish and other aquatic lifeforms.

Bypass stream at Greifenstein power plant with weir

The Danube power plant Greifenstein will be equipped with a new fish bypass in the course of the EU LIFE+ project “Network Danube”. A near-natural stream will help the fish to traverse the 10 metre-high barrier of the Danube power plant. Necessary for this is a 4.4 kilometre-long channel that bypasses the existing, ecologically valuable areas. About 180,000 m³ of gravel have so far been moved in the wetland at the Greifenstein power plant.

The removal of barriers to fish is just one of the goals in the “LIFE+ Network Danube” project. The main objective is the connection of existing, ecologically healthy areas as well as land restoration projects. The Greifenstein fish bypass lies in the European conservation area “Tullnerfelder Donau-Auen”, the biggest continuous wetland area in Austria.

Turbines and generators: Nine horizontally installed Kaplan bulb turbine with an average head of 12.6 metres have a bottleneck capacity of 293,000 kW.

Weir system: Six hydraulically controllable pressure segments with flap gate on top close the weir system. The Greifenstein power plant was built between 1981 and 1985 in the dry construction method and co-financed by EVN and Wien Strom GmbH.
