Introduction

The WES32/100 is a two bladed, high performance, reliable midsize 100kW wind turbine with a rotor diameter of 32 meters.
The mechanical part of the WES32/100 is based on the original, proven design from 1983. For the electrical parts providing power conversion and control, the latest technology is used.
WES32/100 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.
