2.3M120

Turning low wind speeds into high revenues.

The Senvion 2.3M120 is the ideal turbine for low-wind speed sites and boasts a high capacity factor. It has a rated power output of 2.3 megawatts at a wind speed of 12 m/s, thanks to its larger rotor diameter of 120 metres.

  • Nominal power: 2,330 kW
  • Rotor diameter: 120 m
  • Hub height: 90 -120 m


  • Wind class: Low wind
  • Operating temperature range: -20 – +40 °C
  • Rotor surface: 11,310 m²

Senvion Technology

The 2.XM series combines time-tested technologies with innovative features to further increase reliability, efficiency and yields. The power output is controlled by an electrical pitch system which adjusts the pitch angle by means of three separate actuators – one for each of the three blades – for high system reliability. The electrical system consists of a synchronous generator with a full conversion IGBT-converter for stable output and global grid compliance. The power conversion system decouples the internals from grid influences and protects the turbine electronics from electric grid loads. An internal supply unit provides the turbine with constant voltage and frequency in the event of a grid shutdown. A combined cooling circle for the mechanical and electrical drivetrain and the power electronics enables a further increase in efficiency.
