3.4M122 NES – Best for Mid-Speed Winds

Along with an increase in nominal power to 3,400 kilowatts, the successor to the 3.2M122 is also certified for wind class IEC IIA and locations in wind zone 4. The energy yield at mid-speed winds and a hub height of 139 meters is up to 2.4 percent higher. This new system provides improvements in two essential areas. Firstly, it further increases the efficiency of energy production and secondly, it helps integrate renewable energies more sustainably into power networks, by improving electrical capabilities.


Highlights

  • Nominal power 3.4 MW
  • 122 meter rotor diameter
  • Certified for wind class IEC S based on IEC IIA
  • 2.1 % higher energy yield compared to 3.4M114 NES
  • Wide range of tower heights available
  • Next Electrical System (NES) compliant with stringent grid requirements
