Steinfeld Run-of-River Power Plant

VERBUND's power plant at Steinfeld is a run-of-river power plant situated on the river Grabach and in the municipality of Steinfeld in Carinthia. It was constructed from 1936 (its predecessor 1924) by the cooperative society of the municipalities of Steinfeld, Kleblach, Lind, Weisach, Greifenburg, Lessnig and Obergottesfeld.

History of the Power Plant 

Steinfeld power plant was built in 1924 by a cooperative society comprising the five municipalities Steinfeld, Kleblach, Lind, Weisach and Greifenburg. In 1935, the building was destroyed by a rockslide which also claimed the life of the watchman. Electricity was then supplied by Mühldorf power plant on the basis of an electricity supply agreement. The terms of this agreement were, however, very unfavourable for the municipalities of the cooperative society. A decision was therefore taken to construct a new power plant in a cavern 30 metres inside the mountain so as to protect it from future rock fall, avalanches and mudslides. In the meantime, the power plant cooperative had two new members, namely the municipalities of Lessnig and Obergottesfeld.

In the course of the nationalisation of the electricity industry after 1947 the power plant was taken over by Kärntner Elektrizitäts-AG (KELAG), in spite of fierce opposition from the cooperative. By way of compensation, the members of the cooperative received from KELAG payment in kind in the amount of 26 KWh per share over a period of 30 years.

Following the diversion of the Grabach for the storage power plant Reißeck-Kreuzeck in 1956, Steinfeld power plant was purchased by Österreichische Draukraftwerke AG (ÖDK) and numerous adaptation measures were carried out in the following years.

Machine one was decommissioned in 1995 and a new generator was installed in machine two.
