The Garsten power plant was built between 1965 and 1967. The installation of an IT control system and the replacement of the three static exciter sets took place in 1999. Three vertical Kaplan turbines generate an annual average of approx. 163 GWh of electricity.

Ecology & environmental protection

A fish bypass for the Großraming site is currently being evaluated. A feasibility study of ecological measures (German only) on the Enns was carried out in 2017 by the University of Natural Resources and Life Sciences Vienna (commissioned by: Office of the Provincial Government of Upper Austria, Office of the Provincial Government of Styria, Ennskraftwerke AG and VERBUND Hydro Power GmbH).
Responsible treatment of the environment
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.
