Nordex Group Installs the First N149/5.X Turbine


Nordex Group has installed the first N149/5.X turbine, at the Genshagener Heide wind farm near Potsdam, Germany. 

In spring 2019, the Nordex Group opened the market segment for 5 MW turbines of this turbine type. This month, the first N149/5.X turbine will start operations on schedule. Following the installation of the turbine, preparation will begin for the measuring and validation program for the type certification of the N149/5.X.  

With mean wind speeds of 6.4 m/s at the hub height of 105 meters, the site offers good conditions for measuring the 5.7 MW turbine. In addition to the power curve, the Nordex Group will be validating the sound power level and grid compatibility of the turbine on with measurements recorded in the field. This means that for the start of the series production in 2021, the turbine will be fully certified – including the type certificate. 

The N149/5.X is a logical progression based on the successful approach of a flexible rating of the N149/4.0-4.5. The turbine is designed for maximum flexibility and can be operated in different modes in the 5 MW range, depending upon on-site requirements and customer needs. A new gearbox will be used and the electrical system of the Delta4000 series has been scaled up in order to achieve power output in the 5 MW range.

To date, the Nordex Group has received orders for 800 MW of the N149/5.X.
