This turbine is rated at IEC 5 for an average wind speed of 11 m/s. The design gives a peak efficiency of close to 40% at a wind speed of 9 or 10 m/s.

The turbine drives a permanent magnet generator through a gearbox.

It is designed for a 25 year life and is intended for offshore use where high mean wind speed can be expected i.e. North Sea at 10 m/s. The Weibull shape parameter is quoted at 2.2 which corresponds to a wind standatd deviation of 48% of the mean wind speed. At 10m/s, the turbine would produce a mean power of 3.985 Mw giving a capacity factor of 0.57.
