Vestas Wind Systems A/S Wind Turbine V136-3.45 MW™

V136-3.45 MW™ combines Vestas' most advanced aerofoil design to date with the proven 3 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, decrease the max noise emission level relative to current designs. 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. * Compared to V117-3.3 MW™ IEC IIB classification of Vestas’ largest turbine 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. *Compared to V117-3.3 MW™. Actual figures depend on site-specific conditions. 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’ 3 MW platform, which has already reached 11 GW of installed capacity and more than 14 GW of firm and unconditional orders worldwide. First V136-3.45 MW turbine installed Development of V136-3.45 MW is progressing to plan with the first turbine having been installed in December 2016. As part of the development and verification process for the V136-3.45 MW turbine, the first turbine was installed at the østerild national test center for large turbines in northern Denmark. The turbine will undergo an extensive test and verification programme before commencing full-scale production, expected in second half of 2017.
