The two power plants of Hofmühle and Theresienthal – both located on the River Ybbs – have been regarded as old and outdated for many years. The structure of the buildings …

…and technical equipment seemed to be suitably dilapidated. The end was in sight. Over the last two years, a single, modern run-of-river power plant has now been constructed to replace the two existing plants. This has not only restored the ability of the fish to gain access in both directions at the site of the power plant, but also pushed the generation of electricity to previously unknown heights. With the two Kaplan S bulb turbines from GLOBAL Hydro, the new plant belonging to the Soravia Group produces around 12.8 GWh in a normal year. This represents an increase in yield of around 80 per cent compared to the old existing facilities. Thanks to the establishment of the underwater section rich in structure, it can be expected that the ecological conditions of the waterways will be enhanced in the medium to long term – and the new power plant also represents an improvement with regard to flood protection.
