Also, the torque of runner blades and guide vanes was measured. All values agreed very good with the values of the CFD design. The end customer thus accepted the layout. In the future, the 11,4 MW hydropower plant in the river Mur will generate about 54,2 GWh of green, CO2-free electricity annually and feed it directly into the regional grid.
