Aschach was the second Danube power plant to be built in Austria between Sauwald and the Mühlviertel from 1959 to 1964. The power plant dams the Danube up to a height of 14.9 metres and thus has the highest head of all Danube power plants in Austria. After more than 40 years in operation, the main machines at the Aschach power plant were renewed from 2006 to 2010. Four machine sets, each consisting of a Kaplan turbine and a three-phase generator, generate an average of 1,665 GWh of electricity per year. In the coming years, the power plant will be equipped with a fish pass as part of the LIFE Blue Belt Danube Inn project.

Numerous structuring measures were undertaken in the Aschach storage area from 2007 to 2014: Fine sediment biotopes were protected against wave impact by gravel banks, shingle banks were improved to create gravel zones, and 10 short groynes were create to make the shoreline more diverse. Doing so enabled the creation of further habitats for fish and other forms of aquatic life.
