The hydropower plant Bettenhausen (originally called Heimbach power plant ) is a run-of-river power plant in the Glatttal near Dornhan in the Rottweil district . It uses the hydropower from Glatt , Lauter and Heimbach to generate electricity. The facility is a listed building .
history
Since 1904, the Glatten power station (later the Glatten-Weitenburg overland station ) has been supplying the region with electricity, most of which was generated from steam power . During and after the First World War , a lack of coal led to bottlenecks in electricity generation. As a result, the first plans for an efficient hydropower plant were made . The Oberämter Freudenstadt , Horb , Oberndorf and Sulz founded the district association Heimbachkraftwerke in 1919/1920 , which later took over the overland plant.
The plan envisaged three construction phases: first, a is in the upper Heimbachtal reservoirs created as underground storage with supply of smooth and Lauter. A power plant near Leinstetten uses the drop height of around 50 meters to generate electricity. Later, the water will be fed into a tunnel into the Neckar valley and the power plant will be relocated to Dettingen . Another large reservoir above Leinstetten was planned to compensate for seasonal fluctuations. In fact, only the first phase of construction was carried out. The power plant was built in Bettenhausen to take advantage of the 10 meter higher gradient.
After almost two years of construction, the Heimbach power plant went into operation on March 2, 1923.
With excess external current, water could be pumped back into the storage basin through the pressure pipe. For this purpose, the Glatt near Bettenhausen was dammed into an equalization basin. However, the pumped storage operation was stopped after a few years. The compensation basin, which was no longer required, was dismantled in 2011 and the Glattufer renatured.

The power plant was designed as a high pressure diversion power plant . In Glatten , the water from the Glatt is dammed up at a weir and channeled to another weir on the Lauter. From there a 6.2 km long inlet tunnel leads to the dam . On the way, water from the Lippbach and Wühlbach streams is added.
The Heimbach dam is located below the Loßburg district of Sterneck . The 50 m long and 12 m high dam is designed as a gravity dam and clad with natural stones. The approximately 900 m long reservoir has a volume of 158,000 m³.
The water flows through a 2.8 km long pressure tunnel to the surge tank above the Bettenhausen power station. On the way, water from the Türnenbach is introduced through a 16 m deep shaft. A pressure pipeline with a nominal head of 62.1 m leads from the surge tank to the four Francis turbines in the power house .
