Technical Description 

The Wallnerau-Unterwasser (tailrace) run-of-river power plant was constructed between 1987 and 1989. During the work done on the Wallnerau-Unterwasser power plant, the processed works water from the Schwarzach power plant was channelled into the Salzach, by-passing the construction pit. Three horizontally built-in Kaplan s-turbines with DC coupled three phase asynchronous generators generate annually around 17 GWh of electricity.
