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
