With a rotor diameter of 110 meters, the NEG Micon 4.2 MW will be one of the largest wind turbines available in the market.
A contract to certify this wind turbine has been signed with NEG Micon A/S in Denmark. The NM 110/4200 has a rotor diameter of 110 metres (blade length of 54 metres) and a nominal output of 4.2 MW.
The certification work will be carried out according to the new international wind turbine certification scheme, IEC WT01, utilising the DNV/Risø Guidelines for Design of Wind turbines. From this certificate national certificates can be derived, if requested.
DNV's Wind Turbine Certification department currently certifies offshore wind turbines for NEG Micon, Vestas and Bonus, all Danish companies that will probably be the first choice for many future offshore wind turbine installations. These companies have close to 50% market share and compete with German, Spanish and American companies like, Enercon, Nordex, Gamesa and GE Wind.
DNV's Wind Turbine Certification department at Risø has participated in a technical collaboration with the Risø National Laboratory since 1987. The Danish wind turbine industry currently employs 20,000 people.
