In order to be able to better meet the increasing demand for wind turbines expected by its customers in the coming years, the Nordex Group (Hamburg, Germany) is expanding its turbine fleet with the N175/6.X, another highly efficient Delta4000 series wind turbine.

The new turbine is said to use proven technical concepts from the Delta4000 series, such as its control system, flexible rated power and large parts of the nacelle from its sister model, the N163/6.X, which have already been tested in the field. As a result, in addition to an efficient development process, already tested and existing suppliers and production capacities can also be used for the new turbine.

With a single-piece, newly designed 85.7-meter-long rotor blade, the N175/6.X achieves an above-average capacity factor, according to the company. At typical low-to-medium wind locations, the N175/6.X will achieve between 7-14% more yield compared to its predecessor models, the N163/5.X and N163/6.X, Nordex Group notes. Due to the turbine’s larger rotor, this additional yield is achieved particularly during times of light wind speeds where the turbine produces up to 22% more energy than its predecessor—  this is advantageous for operators, as electricity prices are usually higher during low-wind periods.

The wind turbine will be available worldwide, but Nordex expects the main demand to be in Europe, especially at the beginning of series production.

The N175/6.X will initially be offered with hub heights of between 112 and 179 meters, which enables the turbine to reach attractive wind speeds even in locations with typically light winds. The turbine is designed for an operating lifetime of 25 years, but in some site-specific circumstances can also be confirmed for up to 35. At a rated output of 6.22 negawatts (MW), the maximum sound emission is 106 dB(A).

Nordex also offers a wide range of options for the N175/6.X in order to meet the diverse economic and permit requirements. Among other things, the turbine can be equipped with a bat module and on-de­mand nighttime mark­ing. In addition, and, like the other turbines of the Delta4000 series, it offers different operating modes for reduced sound emissions. A cold climate variant ensuring operation in environments of -30°C is also available.

In May 2022, the Nordex Group installed its first 6 MW N163/6.X turbine. Scheduled series production of the N175/6.X is scheduled for the end of 2024. Among other things, the nacelle will be produced at the company’s German production facility in Rostock. The wind turbine will be available worldwide, but Nordex expects the main demand to be in Europe, especially at the beginning of series production.
