The Nordex Group has obtained the Equipment Certificate (UGE) required in Spain for connection to the grid for the N149/4.0-4.5 turbine as well as the Component Certificate (CAMGE) for its own Wind Farm Controller (CWE).Both certificates confirm the required standard-compliant grid connection behaviour according to the Norma Técnica de Supervisión 2.1 (NTS) by the FGH certification body (FGH Zertifizierungsstelle). These certificates have been required for the connection of wind turbines to the grid in Spain since mid-2020 and have to be provided within two years. Measurement of the N149/4.0-4.5 was conducted in Germany in the Wennerstorf wind farm to the south of Hamburg. These data form the basis for certification of the N149/4.0-4.5 for the Spanish market, which was recently performed by FGH Zertifizierungsgesellschaft mbH in Aachen.
