VETT technology was developed to reduce costs per kW and provide shorter payback times for low-head hydropower projects. It is a cost-focused approach for economically challenging locations.
Its technology purpose is to provide an alternative to archaic low-head hydropower turbines that are typically very large, slow rotating and too expensive for low-head projects. It does this by making use of the venturi principle to achieve a pressure amplification for conventional turbines, allowing the use of much smaller and faster turbines and thereby achieving a project cost reduction.
VETT is verified by England's Environment Agency as fish-safe with zero mortality risk, no noise emission and very little visual intrusion, allowing it to address problems that others can’t.
