What is VETT technology?

VETT stands for Venturi-Enhanced Turbine Technology. Its patented design uses venturi principles to achieve a pressure amplification for a conventional axial flow turbine. ​This allows compact, high speed, no gearbox turbines to be used in ultra low head hydro settings of 4 metres or less, decreasing project costs significantly.

What does 'low head hydropower' mean?

The use of terminology is not always consistent across the hydropower industry. ‘Low head’ can refer to heights of 10 metres or heights of 3 metres, depending on the technology offered by different companies.


At VerdErg, ‘low head hydropower’ means head drops of 4 metres or less. This is because our compact technology is able to generate cost effective power from such ultra low sites.
