Renewable EnergiesHydropower Plants at Danube and Iller
History
1893: Formation of the communal electric utility in Ulm to power an electrical tram first hydropower plant in 1899
Textile and metal working industry settled down because of the hydropower potential
1960: More then 50 % of electrical demand was covered by hydropower
