V126-3.45 MW™ at a Glance

Built on the same proven technology as the V112-3.0 MW®, the V126-3.45 MW™ IEC IIA/IEC IIB operates on medium-wind sites. Equipped with the industry known structural shell blades, the blades of the V126-3.45 MW™ turbine do not weigh more than those of the V112-3.0 MW®. The 126 m rotor enables greater wind capture, which in turn produces more energy at a reduced cost. The result is exceptional profitability in areas with low wind, and new frontiers for wind energy investment.

3 MW Platform

 

Our 3 MW platform is designed for a broad range of wind and site conditions, onshore and offshore enabling you to mix turbines across your site or portfolio of sites, delivering industry-leading reliability, serviceability and exceptional energy capture.

The 3 MW platform was introduced in 2010 with the launch of the V112-3.0 MW®. Since then more than 11 GW of the 3 MW Platform has been installed all over the world onshore and offshore making it one of the most popular platforms in our portfolio.

Rotor diameters range from 105 to 136 meters and the rated output power is 3,450 kW. Using well proven technologies like a full-scale converter, the 3 MW platform meets even the most challenging grid requirements providing excellent energy yield in all wind and weather conditions.

Large Diameter Steel Towers (LDST) are also available to optimise annual energy production on low wind sites.

The 3 MW platform combines Vestas’ proven track record with our continuous efforts to improve and optimise our products, making it the obvious choice for customers looking to combine reliability with performance.
