Nordex N149/4.X Wind Turbine
Nordex N149/4.X Wind Turbine
Highly flexible siteability. Adaptable to various site conditions.
With the N149/4.0–4.5, the Nordex Group was the first company to launch a turbine with a flexible rating as part of its core design philosophy and operation strategy. This design approach, combined with a variety of operating modes, enables the utilization of the N149/4.X across a large range of projects – from medium wind projects in Australia to highly complex sites in Germany or Scandinavia.
The wind farm can be optimized with in terms of AEP, rating, lifetime and sound requirements. In addition, this flexibility offers opportunities to optimize the revenues in line with PPA structures and merchant price profiles.
