Vestas V117-4.2 MW™ Typhoon Onshore Wind Turbine

The V117-4.2 MW™ is designed for medium to high wind speeds, withstanding highly severe climatic conditions, and it boosts performance by 13 percent compared to V117-3.45 MW. 

Applying the existing upgraded gearbox from V136-3.45 MW and V126-3.45 MW Htq, the V117-4.2 MW™ is able to withstand extreme wind conditions, making new sites possible for wind energy projects.

V117-4.2 MW™ Typhoon
The V117-4.2 MW™ Typhoon offers maximum energy production in medium to high wind speeds. It strengthens the 4 MW platform’s performance in extreme wind conditions expanding reach into areas with very strong wind and typhoon type weather. With use of Load Optimized Modes, the V117-4.2 MW™ Typhoon can be sited at complex sites with turbulence levels exceeding IEC class A.
