The Losenstein run-of-river power plant was built between 1958 and 1962 and required the most extensive construction measures in the storage area of any power plant on the Enns, second only to the Großraming power plant. From 1972, Losenstein was operated remotely from Großraming; the control centre in Steyr has managed operations since 2000. Two Kaplan turbines generate an annual average of around 170 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).

Turbines and generators: Two sets of machinery from the years 2002 and 2003, each comprising a vertically arranged Kaplan turbine with a nominal output of 35.55 MW and a directly coupled three-phase synchronous generator with a nominal output of 38 MVA.

Transformers: Each of the two main transformers has an output of 31,500 kVA and a transformation ratio of 6.3/115 kV.

Weir system: Each weir is equipped with two underguards (ground outlets) and a weir gate.
