Nordex Group has won a turbine deal of almost 172MW for three projects that make up the De Drentse Monden en Oostermoer wind farm in the Netherlands.
The order is for 44 N131/3900 turbines, including the foundations, with a total capacity of 171.6MW for Duurzame Energieproductie Exloermond, Raedthuys DDM and Windpark Oostermoer Exploitatie.
Nordex will also service the turbines for 25 years at De Drentse Monden en Oostermoer, which is located south-east of Groningen, in the province of Drenthe near Exloo.
Delivery and installation will start from the second half of 2020, the manufacturer said.
Nordex said that the wind farm will be in the immediate vicinity of the central antenna field of the Low-Frequency Array (LOFAR).
LOFAR, which is run by Astron, the Dutch Institute for Radio Astronomy, is a Europe-wide network of radio antennas.
The antennas are sensitive to electromagnetic radiation, which, like every other electrical device, a wind turbine emits.
The order was awarded on condition that the emission level of electromagnetic radiation would be reduced to a predefined absolute minimum.
In order to ensure that this could be done, Nordex developed a predefined, extremely low-radiation version of the N131 turbine and installed a test unit on site in the summer of 2019.
Astron was able to confirm the very low electromagnetic radiation on site, which meant that the 171.6MW deal could be placed.
Including the test turbine, De Drentse Monden en Oostermoer will comprise 45 turbines with a total capacity of 175.5MW.
Nordex chief sales officer Patxi Landa said: “We are pleased to have been awarded the contract for this challenging project.
“At the customer’s request we have successfully implemented a new technological solution.
“Now we can offer our N131 turbines for other projects with similarly demanding requirements regarding minimal electromagnetic radiation.”
