MM92

Our bestseller for medium and low wind speeds

The Senvion MM92 has a rated power output of 2.05 megawatts at a wind speed of 12.5 m/s, thanks to its significantly larger rotor diameter of 92.5 metres. This makes it the ideal turbine for medium to low wind speeds. The MM92 produces energy so powerfully, efficiently and reliably that it has become our top-selling turbine. It is based on the dependable generator gearbox technology of the MM82.
