The WES100 is a two bladed, high performance, reliable 100 kW midsize wind turbine with a rotor diameter of 18 meters. This wind turbine is especially designed for areas with a higher wind speed. The mechanical part of the WES100 is based on the original, proven design from 1983. For the electrical parts providing power conversion and control, the latest technology is used. WES100 turbines are manufactured and exported by WES in the Netherlands, and are sold, installed and maintained all over the world by a global network of certified and trained dealers.

The WES 80 is available with our elegant new cover.
