Hydropower Plant Stegenwald

A new design for a hydropower plant at a long-discussed location on the Salzach River in Austria requires cost savings and the minimisation of building space in a sensitive natural area to obtain a permit for construction. 

In order to realise a reduction in the overall width of the power plant, the idea was born to turn a classic vertical Kaplan turbine with a concrete semi-spiral case by 90 degrees horizontally and to replace the elbow-type draft tube with a straight draft tube. At present, the inflow passes downwards via a horizontal screen into the specially shaped concrete spiral.

To save construction depth, the unconventional spiral was designed in accordance with the idea of a pump intake sump. In the event of a flood, the weir installed above the turbine downstream of the screen can release additional water to the tailwater. …
