The power plant has a capacity of 40 MW, which is applied by two Kaplan turbines. It uses the slope of the Aare on a river length of 7.3 km, which exploits a mean drop height of almost eleven meters. The generator of the northern group of turbines generates electricity with a frequency of 50 Hz for the national supply, the generator of the group located south generates traction current with a frequency of 16⅔ Hz.
