VERBUND’s Greifenstein power plant is a run-of-river power plant on the Danube, situated in the municipality of Stockerau in Lower Austria.
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 "Giessgang" created during construction of the power plant remains a milestone in the ecological design of power plants. 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.
