Nordex has commissioned TÜV SÜD to carry out the type certification of their new wind turbine N149/4.0–4.5. The new wind turbine N149/4.0-4.5 has a rated output of 4.5MW and a rotor diameter of 149.1 metres and can also be operated in alternative modes, depending on site specific requirements, at a maximum output of between 4.00MW and 4.50MW.

It is installed onshore with hub heights between 105 and 164 metres and is also suitable for cold climate sites. Within the scope of wind turbine type certification, TÜV SÜD's experts will examine and assess the overall design and all key components of the wind turbine. 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 building code. Completion of certification, followed by market launch and serial production, is scheduled for 2019.
