The Kiebingen hydropower plant is a run-of-river power plant on the Neckar in Kiebingen , which belongs to the city of Rottenburg am Neckar . EnBW Kraftwerke AG is the owner and operator .

history

Combined coal and hydropower plant in 1910
Turbines of the Kiebinger power plant after the renovation in 1912

The power plant was built by the Junghans brothers from 1902 to 1903. At first it had four Francis turbines , but they were replaced by vertical Francis shaft turbines in 1924/25, which managed without an intake structure. For a while there was also a small steam power plant at the site of the hydropower plant. In 1996 the weir underwent a thorough renovation for safety reasons. Until then, the weir, which was equipped with 14 weir fields each 3.4 m wide, was 56 m wide and had a dam height of 3.3 m, which has now been replaced by a rubber weir. In the following years, further extensive modernization measures were carried out: For example, the turbines were replaced with new ones due to lack of efficiency. The first two new propeller turbines went into operation in April 2001, the other two in early 2003. The new turbines were numerically optimized at the Institute for Fluid Mechanics and Hydraulic Fluid Machinery at the University of Stuttgart and dimensioned in such a way that the existing suction pipe did not have to be adapted. With the new turbines, it was possible to achieve an energy yield that was around 30% higher. A fish ladder was built in 2004.

Today's technology

The four Kaplan turbines generate a flow of a total of 22.87 m³ / s and a drop height of 8.3 m, an electric power of 1.65  MW . Each of the new turbines has eight turbines. The approx. 47 m long, two-field weir is designed as a rubber weir and in this design was at times the largest in Europe. The two weir fields are each 23 m wide and have a storage height of 3.3 m. Below the weir is a 21 m long and 50 m wide stilling basin .

The power plant has a fish ladder . This is designed as a combination structure of bypass water and basin slot pass and has a length of approx. 257 m and a water flow of approx. 500 l / s.
