Nordex Group is expanding its offerings with another turbine in the Delta4000 series: the N175/6.X. The new turbine uses the concepts of the Delta4000 series, such as the control system, the flexible rated power and large parts of the nacelle of the sister model, the N163/6.X, which has already been tested in the field.
With its single-piece, newly designed 85.7-meter-long rotor blade, the N175/6.X achieves an above-average capacity factor. At typical low- to medium-wind locations, the N175/6.X will achieve between 7% and 14% more yield compared to its predecessor models, the N163/5.X and N163/6.X, the company says. 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 predecessors. This is advantageous for operators, as electricity prices are usually higher during low-wind periods, and the N175/6.X ensures high electricity production already at low wind speeds.
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 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 night-time 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.
The N175/6.X will be available worldwide.
“The global energy transition cannot succeed without onshore wind power,” says José Luis Blanco, CEO of Nordex Group. “With its proven product range, the Nordex Group has been ideally positioned for years to provide the necessary technology for this. With today’s introduction of the N175/6.X, we are making a further contribution to advancing the energy transition in the world and making new wind farm locations economically attractive.”
In May, Nordex Group installed its world’s first 6 MW N163/6.X turbine of the Delta4000 series as planned. 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.
