Ecology & environmental protection

A fish bypass for the Weyer location is currently being planned. A feasibility study of ecological measures 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).
Hydropower studies
Turbines and generators: Two Kaplan turbines with a bottleneck capacity of 36.8 MW generate an annual average of approx. 160 GWh.

Transformer: The plant has a 23,800 kVA machine transformer for raising the voltage from 9 kV to 121 kV. The electricity is fed into the 110 kV Amstetten-Küpfern line of Austrian Federal Railways.
