Irvine, Calif.-based Composite Technology Corp.'s (CTC) DeWind subsidiary received certification of the 60 Hz version of DeWind's 2 MW D8.2 wind turbine from DEWI-Offshore and Certification Centre GmbH (DEWI-OCC), according to International Electrotechnical Commission (IEC) requirements. DEWI-OCC is a subsidiary of the German Wind Energy Institute (DEWI).

"This is yet another important milestone in our certification campaign for the DeWind D8.2 family of turbines and provides assurance that the design of our 60 Hz version complies with the internationally recognized high standard for the North American, Central American and Brazilian markets," says Benton Wilcoxon, chairman and CEO of CTC.

The statement of compliance for the design assessment of the wind turbine with an 80 meter (m) rotor diameter and 80 m hub height tower was conducted for IEC Type IIA conditions and in conformance with IEC 61400-1 guidelines. CTC says this process is a rigorous third party independent verification that confirms that the turbine components can be expect to achieve a 20-year design life under operating conditions that are equal to or more demanding than the majority of wind sites in the Americas.
