From knowledge exchange to new solutions: Ukrainian energy specialists explore Austrian hydropower practices
Modern technologies combined with continuous professional development remain key drivers of sustainable hydropower growth. In May, specialists from Ukrhydroenergo visited Austria, where they familiarized themselves with advanced practices and modern approaches to managing energy facilities.
During the visit, the engineers toured the Freudenau HPP in Vienna - an example of the harmonious integration of energy infrastructure, urban development, and environmental responsibility. With an installed capacity of 172 MW, the plant features a near-natural bypass system of the Danube, one of the most advanced in Europe, serving as a critical habitat supporting spawning, growth, and feeding cycles of several Danube fish species.
The Ukrainian experts also studied the operations of the Sellrain-Silz hydropower system. This unique pumped-storage complex, comprising the Kühtai and Silz power plants, is distinguished by large-scale engineering solutions, including the 149-meter Finstertal dam and one of the highest elevation differences in Europe for power generation - approximately 1,250 meters. Water collected from a 139 km² catchment area is pumped to the Finstertal reservoir, enabling flexible electricity generation aligned with demand.
In addition, Ukrhydroenergo’s specialists were introduced to the ongoing construction of the Innstufe Imst-Haiming hydropower project. A key innovation of the project is the reuse of water previously utilized by the upstream Prutz and Imst power plants, eliminating the need for additional water abstraction or new river dams, thereby minimizing environmental impact. The project includes the construction of a 14-kilometer underground pressure tunnel and an underground power plant, helping preserve the natural landscape.
The knowledge gained during the visit will support Ukrainian hydropower engineers not only in reconstructing and restoring damaged hydropower plants, but also in shaping a new, more resilient, efficient, and future-oriented Ukrainian hydropower sector.
