V136-3.45 MW® at a glance

V136-3.45 MW® combines advanced aerofoil design with the proven 4 MW nacelle and Large Diameter Steel Tower (LDST) technology, to deliver high and efficient energy production in low- and medium-wind conditions.

The aerofoil design, applied to the 66.7m long blades, enables a 16 percent* increase in annual energy production while at the same time minimising structural loads. Advanced aerodynamics, particularly at the blade tips, and aero add-ons such as Serrated Trailing Edges decrease the maximum noise emission level.

Vestas has 15 years of experience optimising carbon blade application, and the V136-3.45 MW® benefits from advanced use of carbon pultrusions, resulting in light-weight, highly robust blades with optimal performance. The industry leading lightning protection system and highly accelerated lifetime testing ensure high product reliability.

IEC IIB classification

Supported by focused design and optimisation activities, the V136-3.45 MW® is now capable of operating in both IEC IIIA and IEC IIB wind conditions.

With the IEC IIB classification of the V136-3.45 MW®, the turbine is now covering an even broader range of wind and site conditions, where the 136 m rotor enables great wind capture, at medium-wind conditions.

This makes the V136-3.45 MW® turbine a strong performer with the potential to increase AEP by up to 16 %*, contributing to a lower LCoE.

The V136-3.45 MW® as an IEC IIB turbine is already being applied to medium-wind conditions for projects in North America and Asia, giving our customers the possibility of choosing the V136-3.45 MW® turbine’s compelling balance between advanced technology and proven performance.

First order for the V136-3.45 MW®

Just three months after its launch to the market, Vestas has received an order for 34 V136-3.45 MW® turbines for the 117 MW Metsälä wind power project. When built the wind farm will be Finland’s largest onshore wind project.

The V136-3.45 MW® has been very well-received after its launch, particularly in the low-wind segment across several markets due to the turbine’s compelling balance between advanced technology and proven performance, enabling an increase in energy output and reduction in the cost of energy.

The order for this V136-3.45 MW® large scale project underlines the confidence in Vestas’ 4 MW platform, which has already reached more than 35 GW of installed capacity and more than 21 GW of firm and unconditional orders worldwide.

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 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.
