The Böfinger Halde power plant is the most powerful hydropower plant operated by Stadtwerke Ulm / Neu-Ulm and was commissioned in 1953.

It can also be operated in swell mode, which means that load fluctuations can be better countered by adapting the generation accordingly. The discharge fluctuates from 44 to 300 m³ / s. The two identical turbines / generator sets consist of a Kaplan turbine with a four- blade impeller with a diameter of 3.9 m and a synchronous generator with a nominal output of 5.5  MVA and a nominal voltage of 5  kV . By increasing the drop height from 6.5 to 7.0 meters, the original nominal output of the power plant was increased from 8 MW to 8.8 MW from 2010.

The associated weir, made up of three fields, is formed by a solid-walled gate and two gates with weir flaps. The drop height is 7 meters. The target water level is 466 m. The aim is to have the upstream water level at 466 m.

The average annual generation of the power plant is 51 GWh, which corresponds to an average output of 5.8 MW.

The state border between Bavaria and Baden-Württemberg runs in the middle of the Danube and thus through the facility. The machine house and parts of the weir are in Baden-Württemberg, the rest of the weir system and the boat lane are in Bavaria.
