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.


Highlights

    • Nominal power 2,330 kW, rotor surface 11,310 m2, rotor diameter 120 m, hub heights 90 to 120 m
    • Load-flow optimised mechanical construction with time-proven components for a 20-year operating life
    • Internal Supply Unit: Supplies the turbine with constant voltage and frequency when disconnected from grid
    • Efficient cooling circuit: Combined cooling system for the mechanical and electrical drivetrain
