Nordex: N117/3600 and N131/3600 produce up to a 12% higher yield at sites with moderate and light winds


At the world’s leading wind fair, Windenergy Hamburg, which is being held together with the WindEurope Summit in Hamburg from 27 to 30 September 2016, Nordex will be presenting two new turbines from its multi-megawatt Generation Delta platform: the N117/3600 for moderate-wind sites and the N131/3600 for sites with light winds. Thanks to a 20 percent increase in rated output and sound emissions of up to max.106.4 decibels, these turbines set new standards for the economical production of wind energy at moderate and light-wind sites.

For sites with moderate winds Nordex is launching the N117/3600 with an installed capacity of 3.6 MW. This gives the turbine a 20% higher-rated output than its sister model, the N117/3000. For light-wind sites Nordex has also raised the rated output by 20 percent by introducing the N131/3600 with an installed capacity of 3.6 MW to its product portfolio.

The higher-rated output of the two turbines has a positive effect on their annual energy yields. “With these turbines customers can produce an up to 12 percent higher yield.  It is our declared aim to make electricity production from wind energy increasingly economical by means of our technical developments. By 2018 we at Nordex want to reduce the cost of energy by 18 percent. These two turbines represent a major step in this direction as ultimately they make wind-generated electricity more profitable,” says Lars Bondo Krogsgaard, CEO of Nordex SE.

The sound emissions of the N131/3600 are limited to a max. 106.4 dB(A), which, due to the higher rotation speed, makes it highly competitive. At 105 dB(A), the N117/3600 has the same sound emissions as the N117/3000. Furthermore, Nordex offers both machines with serrations, which reduce the sound emissions by an additional 1.5 dB(A) in each case. These serrations can be found on the trailing edge of the rotor blades and serve to reduce the aerodynamic sound power level overall.Should the customer require it, the turbines can also be operated in reduced-noise modes. This means that these turbines are especially suitable for noise-sensitive markets, such as France, Germany, Scandinavia and parts of Great Britain.

Due to the strong demand for turbines with high hub heights Nordex is currently having its 141 metre tower certified for IEC 2 sites as well. The company therefore offers the N131/3600 with tower heights of 84 to 112 metres, and for Scandinavia, up to 134 metres. The N117/3600 is available with tower heights of from 91 to 141 metres.Nordex plans to install the first of each of these turbine types before the end of 2016. The series ramp-up for bothturbines is scheduled for summer 2017. The type test results will be available this year and the type certificates are expected in mid-2017.

The N117/3600 and N131/3600 are based on the proven Nordex platform technology in order to offer customers a high level of technical reliability. The current light-wind N131/3000 turbine is now fully certified and all parameters have been confirmed, forming a sound foundation for the further evolutionary development of the N117/3600 and N131/3600.
