The power plant was built between 1995 and 1998. As the power plant was built in the dry construction method, a new riverbed had to be created above and below the power plant. Two Kaplan spiral turbines generate an annual average of approx. 60 GWh of electricity.

Turbines and generators: The lower-pressure run-of-river power plant generates approx. 64 GWh of electricity annually with its two machine sets. Each machine set consists of a horizontally installed Kaplan bulb turbine with an impeller diameter of 3.85 metres and a synchronous generator with an output of 8,500 kVA.

Transformers: The plant has a block transformer for raising the generated energy from 6.3 kV to 110 kV.

Weir system: The three weir fields are controlled by means of hydraulically operated pressure segment gates with weir flap.
