4 MW Platform


Our 4 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 4 MW platform was introduced in 2010 with the launch of the V112-3.0 MW®. Over 35 GW of the 4 MW platform has been installed all over the world onshore and offshore making it the obvious choice for customers looking for highly flexible and trustworthy turbines.

Rotor diameters range from 105 to 155 meters and the rated output power is up to 4.2 MW. Using well proven technologies like a full-scale converter, the 4 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 4 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.
