Altenwörth Power Plant on the Danube

Technical description

The Altenwörth power plant was built some 20 km downstream of Krems between 1973 and 1976, and was jointly financed by Energie AG Oberösterreich, Salzburg AG and VKW. Nine Kaplan machine sets with a bottleneck capacity of 328,000 kW make it the most powerful power plant on the Danube. The Traisen estuary was extensively renaturised. In the coming years, the power plant will be retrofitted with a near-natural fish bypass.
