Nordex is expanding its turbine fleet with a new 6MW addition to its Delta4000 series.
The new 6.22MW turbine, the N175/6.X, uses the “proven technical 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.
This means that already tested and existing suppliers and production capacities can also be used for the new turbine, Nordex said.
With its single-piece 85.7 metre-long rotor blade, the N175/6.X can achieve an “above-average” capacity factor.
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.
Due to the turbine’s larger rotor, this additional yield is achieved during times of light wind speeds where the turbine produces up to 22% more energy than its predecessors, said Nordex.
The company stated: “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 metres and is designed for an operating lifetime of 25 years, but in some site-specific circumstances can also be confirmed for up to 35 years.
The maximum sound emission is 106 dB(A) and 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, while a cold climate variant ensuring operation in environments of -30°C is also available.
The N175/6.X will be available worldwide, but Nordex expects the main demand to be in Europe, especially at the beginning of series production.
José Luis Blanco, CEO of the Nordex Group, said: “The global energy transition cannot succeed without onshore wind power.
“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.”
