Hydropower plant and fish-way in the Danube River in Austria

Abstract

The Freudenau dam, which equips with run-off type of hydropower plant with a head difference of 8.7 m, was constructed in 1992-1998 on the Danube River at the central part of Vienna city in Austria. The dam generates 1,052GWh of hydro-electricity annually. The Freudenau is one of the typical dam to confirm the consensus by public election in the beginning of 1990s with 354,533 people of vote for "yes", which amounts to 73% of the citizens in Vienna city. A nature restoration concept was introduced in the early 1990s to construct the by-passing fish-way in the inland wetland with high bio-diversity.
