The Illerkraftwerke are five run -of-river power plants operated by EnBW Kraftwerke AG along the central Iller and at the diversion of parts of the Iller into the Illerkanal between Aitrach in the Ravensburg district and Dettingen an der Iller in the Biberach district , in Upper Swabia .

History and layout

In 1909, the then legal owners, the Kingdom of Württemberg and Bavaria, signed a contract that jointly regulated the hydropower of the Iller for electricity generation. In Mooshausen a was after 1917 weir built, the water extending in a left side parallel to the iller, derives about 41 km long channel. The Illerkanal has a gradient of 50 meters along its entire length . Three canal power plants at the Tannheim reservoir , in Unteropfingen and at the Dettingen reservoir had been built by 1927. The Aitrach hydropower plant , located about four kilometers upstream on the Bavarian side of the weir, was commissioned in 1950, the small hydropower plant at Mooshausen weir in 1994. The Illerkraftwerkgruppe has a total nominal output of 47 MW.

Around 13% of the total electricity provided by EnBW comes from hydropower plants. This makes the energy supply company the second largest producer of electricity from hydropower in Germany. The Illerwerk II Tannheim , built in 1923 , a separate district of the municipality, generated electricity for 36,000 households in 2012, which corresponds to 57.5 million kilowatt hours of electricity.
