Voith StreamDiverTM

Utilizing untapped potential

Today 85% of all existing dams and weirs around the world remain unused for hydropower generation. With their enormous energy potential, taking advantage of them could make a key contribution to an ecological supply of electricity. Voith offers solutions that exploit this potential, generating sustainable energy while remaining in harmony with nature.

For small hydropower plants in particular, Voith has developed an innovative, reliable, and eco-friendly turbine – the StreamDiver. The StreamDiver was designed to keep constructional effort and peripheral equipment to an absolute minimum. This allows for power creation at locations where conventional plants are not viable for economical or ecological reasons. A variety of power plant set ups are available to meet specific project requirements.
