V105-3.45 MW™ at a Glance

With a rotor size of 105 m, the V105-3.45 MW™ IEC IA is the turbine that fits the most severe wind conditions. It has an extremely robust design for tough site conditions and is especially suited for markets with tip-height restrictions and high grid requirements.

The V105-3.45 MW™ blade is a shortened version of the proven and tested pre-preg blade used on the V112-3.0 MW®, the V112-3.45 MW® and the V117-3.45 MW®. Like all 4 MW turbines, the V105-3.45 MW™ is equipped with a full-scale converter ensuring full compliance with the challenging grid codes in countries like the UK and Ireland.

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®. Since then over 14 GW of the 4 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 150 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.
