The Mambach hydropower plant is a run-of-river power plant in the southern Black Forest . It is the oldest and most powerful of the hydropower plants on the meadow , one of the larger rivers in the Black Forest. The power plant is located directly on the B 317 , north of the former municipality of Mambach at the end of the middle course of the meadow. The building is a historical monument.
history
The Mambach power plant was built between 1897 and 1899 and went into operation in December 1899. After commissioning, several communities in the region, including the former village of Mambach, the city of Zell im Wiesental, as well as a spinning mill and a paper factory, were supplied with electricity. In 1990 the power plant was renovated, in 2003 and 2004 the conversion to automated operation followed. Another renovation took place in 2014/2015, whereby the old Francis spiral turbines from the early days were replaced by two modern units of the same type.
technology
The headwater is taken from the river 3.76 kilometers up the river by means of an inlet structure at the Kastler Bridge ( Fröhnd municipality ) and guided over an earth-covered gravity channel (diameter two meters) on the slope to directly above the power plant. The water lock is located there as an introduction into a pressure pipe. With a usable gradient of approx. 37 m, the installed capacity is approx. 1.2 MW. The energy generated is fed in via a 20 kV switchgear with an overhead line connection . The water is then fed back into the river from the turbines via a 200-meter-long underground channel.
