Water to Wire: finding a complete solution with Voith
Small hydropower plants by Voith are sophisticated and reliable solutions for a sustainable energy supply. Our experts at Voith are here to accompany you from the selection of products to the start of operation all the way to the maintenance.
Working with Voith pays off
- Reliable partner
- Technical excellence
- Secure and sustainable solutions
We always keep sight of the entire power plant
By perfectly aligning electric, hydraulic and control components, and developing them in an integrated manner, we are able to optimise the energy production and lifecycle of your plant. For us, efficient power supply means reconciling economic efficiency with environmental friendliness: We consciously and sparingly use natural resources for high capacity utilization to increase earnings.
A step ahead – Individual solutions with standardised products
Our standardised platform concept provides the basis for our small hydropower solutions. Thanks to the ideally aligned components, we are not only able to increase the efficiency of the processes. The use of fewer, standardised and high-quality components also reduces the default probability and facilitates problem solving.
Our expertise for small water turbines
Our portfolio of turbines offers an economical solution for all requirements. For smaller hydropower plants, Voith delivers attractively priced systems in a standardised design – and individually adjusts them to accommodate their environment.

Generators for an optimal energy yield
Thanks to our long-standing experience in the development and production of generators, we are able to perfectly integrate them in your power plant – and optimize the energy yield accordingly. The electric, mechanical and thermal stresses are extraordinarily high in the field of hydropower. This is why we have developed our own range of hydropower generators with a robust generator design and a perfectly coordinated modular setup of the stator and rotor.
