Data and images of Siemens Gamesa’s 21 MW offshore wind turbine

21MW

  • Technology: Siemens Gamesa continues to rely on its Direct Drive technology, even though some competitors (Vestas and some Chinese OEMs) have shifted to the Medium Speed Permanent Magnet Generator with gearbox.
  • Power: According to some rumors, the power could range between 21 and 23 MW, depending on the typical Power Boost function SGRE usually offers for its offshore turbines. This represents a leap of over 50% compared to the SG14.0-236 DD.
  • Rotor diameter: The blades are rumored to be 135 meters long, for a rotor diameter of 276 meters.
  • Output voltage: 132 kV on the high-voltage side of the transformers located in the nacelle. This will likely be the first wind turbine in the world to use this voltage level—typical of substations and high-voltage transmission lines. This leap has been discussed in various forums for a long time and now seems to be materializing.
  • AEP (Annual Energy Production): For the same location, an increase of 30-35% compared to the SG14.0-236 DD.
