TÜV SÜD to certify new Nordex Delta4000 N149/5.X and N163/5.X turbines

The Nordex Group is an international leading supplier of wind turbines. Their focus is on powerful multi-megawatt turbines. The wind turbines N149/5.X and N163/5.X are designed specifically for regions with low to medium wind speeds. They have a variable output in the 5-megawatt-range and rotor diameters of 149 to 163 metres. With hub heights between 105 and 164 metres, Nordex ensures efficient and safe operation even in complex on-site conditions. The N149/5.X and N163/5.X are both based on the proven concept of the N149/4.0-4.5 wind turbine. Representing the next step in turbine evolution, they are the most powerful WTGs in the Nordex portfolio.

Type certification of wind turbines is a procedure recognised at international level for establishing compliance with international standards. Within the scope of wind turbine type certification, TÜV SÜD's experts examine and assess the overall design and all key components of the wind turbine. Certification is aimed at verifying and validating the quality of standard-conforming design and production and the wind turbine's power performance. “Investors, project engineers and wind-farm managers worldwide rely on wind turbines certified according to international standards”, says Jochen Stauber, Project Manager Wind Turbine Type Certification, TÜV SÜD Industrie Service GmbH. “Given this, type certification is regarded as a prerequisite for tendering in international wind energy projects.” Type certification frequently represents the first step within the scope of the project certification process.

Nordex commissioned TÜV SÜD to perform not only type certification, but also type approval of its turbines according to the 2012 DIBt guideline based on German construction law. Completion of certification, followed by serial production, is scheduled for 2021.
