Turbines and generators: Twelve hydro-matrix turbines
with impeller diameters of 1.32 metres each and an average head of 3.8 metres have an output of 4.75 MW. Depending on the time of year, a volume of feed water of between 80 and 225 m³/s must be supplied to the Danube Canal, with up to 132 m³/s being possible. The generated energy is tapped at the Heiligenstadt substation of the regional supplier Wienstrom.
The power plant does not have its own weir system, but instead, as a “flowed-over power plant”, flaps that are installed on the hollow body. At low water, these flaps are raised to reveal the weir body. During normal and high water, the flaps are flipped over to allow the river to flow completely over the weir body.
