In the Francis turbine, water is fed to the impeller in a spiral channel. The blades adapt to the flow speed and water pressure changes caused by atmospheric conditions and seasons, for example. The water moves the curved blades of the impeller, which are connected to the generator. The Francis turbine requires a complex design, but offers maximum performance.

The Pelton runner is similar to a classic water wheel. Water hits the centre of two half-shells (buckets) and is deflected through almost 180°. This converts all of the water’s kinetic energy into mechanical energy, which is used to generate electricity.

The Kaplan turbine is usually built with a vertical axis to make best use of the top-down flow. The incoming water is regulated by the guide channel and directed by the adjustable guide vanes onto the axially arranged adjustable impeller blades, which transfer the energy to the generator. Blade adjustment ensures maximum efficiency under different operating conditions.
