Harnessing affordable clean energy from low head hydropower with fish-friendly VETT Technology

VETT hydropower technology provides affordable clean energy for domestic, community or commercial consumers who want to reduce their electricity bill without harming the environment. Whether powering decentralised mini-grids or exporting to the national grid, fish-friendly VETT technology is ideal for micro, mini and tidal range projects. 

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.

Designed for installation in 1-4 metres head, the compact VETT offers 45% less investment cost, shorter payback periods and improved project returns – typically 40% improved.

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.
