There's a hydroelectric power station located at the Danube near the so-called 'Böfinger Halde' in Ulm, Baden-Württemberg, Germany.
The power station 'Böfinger Halde' is the most powerful hydroelectric power station of Stadtwerke Ulm / Neu-Ulm and was commissioned in 1953.
It can also be used in the threshold operation, which load fluctuations can be better addressed through appropriate production adjustment. The drains vary 44-300 m³ / s. The two identically constructed turbine / generator sets consist of Kaplan turbine with an impeller diameter of 3.9 m and a synchronous generator with rated power 5.5 MVA, a rated voltage of 5 kV. The original rated output of the power plant were 8 MW. The nominal capacity of the plant is 8.8 MW and since 2010 has been achieved by changing the drop height of 6.5 to 7.0 meters.
The associated weir of three fields is formed by a solid wall contactor and two contactors with spillway gates. The drop height is 7 meters. The desired water level is 466 m. It is therefore desirable that the level of the upstream water is 466 m.
The average annual production of the power plant is 51 GWh, which corresponds to an average power of 5.8 MW.
