WES 34/100

FER optimized wind turbine
Sustainability and Profitability At local level

Introduction

The WES34/100 is a two bladed, high performance, reliable midsize 100kW wind turbine with a rotor diameter of 34 meters. The mechanical part of the WES34/100 is based on the original, proven design from 1983. For the electrical parts providing power conversion and control, the latest technology is used. WES34/100 turbines are manufactured and exported by WES in the Netherlands.

The turbines are sold, installed and maintained all over the world by WES and our global network of certified and trained dealers.
