Turbines and generators: Two vertically mounted Kaplan turbines achieve a maximum output of 17,000 kW at a flow rate of 160 m³/sec. and a head of 12.20 metres. The two directly coupled 18,000 kVA three-phase synchronous generators supply a nominal voltage of 6.3 kV. The power plant’s own requirements are met by a 353 kW Francis turbine coupled with a 500 kVA three-phase generator.
Transformers: To raise the generated energy from 6.3 kV to 110 kV, the power plant has a 20,000 kVA machine transformer and a 24,000 kVA transformer. The electricity is conducted via two 110 kV lines each to Steyr and Großraming. The upstream power plants at Losenstein and Ternberg feed into the open-air switchgear at Rosenau. Three transformers are available to supply the power plant’s own requirements.
Weir system: All four weir fields are equipped with double hook gates with a closing height of 13.7 metres each. They can be controlled by two chain winches with mechanical shaft.
