    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.

        years of experience in the development of high-performance technologies for small hydropower.

        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.

        Technical Data

        Power range 3 MVA up to 35 MVA
        Voltage range 3,0 kV up to 13,8 kV
        Axis Horizontal or Vertikal

        Know-how from a full-service provider

        Here at Voith, we combine top know-how in plant engineering with comprehensive experience in the field of modern digital systems. This allows us to turn your small hydropower plant into an integrated and optimised overall system.


        With the Voith Small Hydro HyCon solution, you can benefit from the large hydro world - even for small-scale hydropower plants. We do not consider automation separately. Instead, we optimise the complete system of small hydropower plants hydraulically, electrically and on the process side.

        Shut-off valves

        Voith started designing shut-off valves as mechanical-hydraulic control equipment for water turbines over a century ago. This way, even small hydropower plants can cope with extreme adjusting forces and short closing times.

        Balance of Plant Electrical Systems (BoP-E)

        From design to integration to set-up and adjustment, Voith is also your small hydropower partner for electrical power plant equipment. Amongst other things, our systems include HV switchyard AIS / GIS, power transformers, generator circuit breaker, earthing and lightning protection.

        Balance of Plant Mechanical Systems (BoP-M)

        Our mechanical systems for the power plant equipment are also planned in an integrated manner and tailored to the overall system. This includes cooling water, dewatering and drainage systems, compressed air supply, crane equipment, fire protection as well as heating, ventilation and air conditioning.

        Hydraulic Steel Structure

        Bulkheads, safety gates, inlet rakes and rack-cleaning systems are absolutely essential for the smooth operation of the plant as well as the protection of the turbines – and they are part of the Voith safety concept. The simple and standardised components for small hydropower ensure the efficiency and environmental compatibility of the plant.

        Eco-friendly products

        We set new standards in terms of nature conservation: our small hydro solutions are based on technological innovations with the objective of keeping the environment healthy and clean. Oil-free turbines and fish-friendly rotor blade concepts help to adapt the small hydropower plants to their natural local environment.
