Turbines and generators: The two main machine sets and the residual water machine have vertically mounted Kaplan turbines, the three-phase synchronous generators are directly coupled. The main turbines have a nominal output of 15.5 MW. The residual water turbine has an expansion output of 1,943 kW and the associated generator a nominal apparent power of 2.35 MVA.
Transformers: Both main machine sets deliver the energy to the Steyr substation via a common transformer and an approx. 4 km-long 110 kV three-phase line. In addition to the 110 kV open-air switchgear, a 30 kV indoor switchgear was installed for supplying the locality from the residual water generator.
Weir system: The three weir fields are equipped with segment gates with weir flap. At a closing height of 12.80 metres, the lift height of the segments is 10.50 metres. The segment gates are controlled by hydraulic cylinders, the weir flaps with a vertical height of 2.75 metres via plungers (vertical hydraulic lift cylinders). Since the year 2000, the power plants on the Enns have been controlled from the control room in Steyr.
