Greifenstein Run-of-River Power Plant

VERBUND’s Greifenstein power plant is a run-of-river power plant on the Danube, situated in the municipality of Stockerau in Lower Austria.

Technical Description 

The Greifenstein power plant was built from 1981 to 1985 using the dry construction method and was co-financed by EVN and Wien Strom GmbH. A left curve of the Danube was in this way shortened by a filament and the power plant could be built in one single construction pit without being affected by shipping traffic. Nine horizontal Kaplan bulb turbines generate an average yearly output of around 1,717 GWh. 

In the next years, the power plant will be equipped with a modern fish ladder. You can find information on the LIFE+ Network Danube project here.

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.
 
Visit to the Greifenstein fish bypass
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.
