Nordex reports that its N117/3000 and N100/3300 Generation Delta turbines have received all design evaluation certificates in accordance with the IEC standard Design Evaluation Conformity Statement. In addition, the company notes it has already installed three of the next-generation turbines in Germany and Denmark.
As part of the certification, TUV Nord reviewed the design of Nordex's turbine configurations in all tower, climate and frequency versions.
The N117/3000 with tower heights of 91 and 120 meters is certified for medium wind speeds, while the 141-meter version mounted on a hybrid tower is certified for low-wind locations of up to 7.5 m/s.
Certificates for hub heights of 75 and 100 meters have been received for the N100/3300. In addition, all turbines have been awarded DIBt type approval for the German market. Accordingly, Nordex says all relevant documents required to apply for building permits are now available.
Furthermore, Nordex has assembled and installed its first Generation Delta turbines. An N117/3000 mounted atop a 91-meter steel tube tower and an N100/3300 with a hub height of 100 meters are to be connected to the grid at the Janneby wind farm in Schleswig-Holstein, Germany, in the near future. The company says preparations for the measurement and validation program for type certification are proceeding at full swing at the wind farm.
An N100/3300 turbine with a 75-meter hub height has already been installed at a strong-wind site at the Riso/DTU wind-testing field operated by the National Laboratory in Bovlingbjerg, Denmark, directly on the North Sea coast.
This is to be followed by the installation of two N117/3000 turbines later this year – one with a hub height of 91 meters and the other with a hub height of 120 meters – in Raahe, Finland, under a contract Nordex was awarded in February by Raahen Tuulienergia Oy.
This coming winter, the company will also be mounting an N117/3000 on a 141-meter hybrid tower at the Kohlbrandhoft site in the port of Hamburg, Germany. Nordex says this means that over the next few months, Generation Delta turbines will be operating at all available tower heights.
Nordex plans to commence series production of Generation Delta at the beginning of 2014. The first major project under contract – encompassing 24 cold-climate versions of the N117/3000 turbine plus an anti-icing system – is to be installed in northern Sweden next summer.
