The hydropower plant Fridingen in Fridingen on the Danube in the district of Tuttlingen in Baden-Württemberg united in a power house the machines of a hydroelectric power station of Bara and a loop power plant of the Danube . Until 1961, a pumped storage power plant was also part of the power plant.

Danube power plant Fridingen

The Danube power plant Fridingen of EnBW Energie Baden-Württemberg is a diversion power plant on the Danube and went into operation in 1923. The associated weir in the Danube is located around river kilometer 2728.6 and consists of five fields with slide gates. The generators on the three Francis turbines generate up to 4.4 GWh of electrical energy per year  , with an installed electrical output of 1.2  MW . The fall height is up to 16.2 m.

Danube tunnel Fridingen

The Donaustollen Fridingen is a diversion channel of the Danube and was built in the 1920s in order to be able to use the approximately 16 meter gradient of the approximately eleven kilometer long flow section of the Danube loop in a hydropower plant. The total length of the artificially created watercourse with the water body code GKZ 1,117,120,000,000 is 1.919 km.

The first 250 m long section from the inlet at Danube kilometer 2728,653, about 50 m above the Danube weir in Fridingen ( ), to the machine house of the hydropower plant is an open channel. From the machine house, the water flows 1.4 km in the mine-built 2.6 m high and 2 m wide tunnel. From the eastern portal of the tunnel to the outlet back into the Danube in the area of ​​the municipality of Beuron at river kilometer 2717.784 there is an open channel of 250 m length.

Bear power plant

In the Bärakraftwerk, the gradient between an impoundment of the river and the nearby confluence with the Danube was used from 1915, thus achieving an output of up to 70 kW. This could generate up to 200  MWh per year. The machines are no longer operational but have been preserved as of 2017.

pumped storage power plant

The expansion by a pumped storage power plant with 500 kW took place in 1922. After the test plant built by Voith in Heidenheim an der Brenz in 1908 and the plant built by Gminder in Neckartenzlingen in 1914, the Fridingen pumped storage power plant was the third pumped storage power plant in Germany . It was the first system of its kind to be built in Germany by a public electricity supply company. The storage basin with a volume of 32,000 cubic meters was located on the Gansnest mountain nose, around 170 meters above the Fridingen power plant. The pumped storage power plant was shut down in 1960/1961 and largely dismantled.
