The Vestas V90 is of a new engineering generation, compared to the V80, resulting in more energy production, better power quality control and less weight.
This type has versions for the IEC classes I to II. For the 1MW extra above the 2MW version, the increase in weights is relatively very low. With the choice for any wind turbine type (Vestas and other), World Wide Wind Turbines always assists in creating clear service & maintenance agreements, with solid SLA's.
