Wind turbine OEM Nordex has won an order to supply 44 of its N131/3900 turbines to a wind farm in the North of the Netherlands consisting of three projects located close to an array of radio-astronomy antennas that are highly sensitive to electromagnetic radiation.
Nordex for the Drentse Monden en Oostermoer (DMO) projects southeast of the city of Groningen has developed an extremely low-radiation version of its N131 turbine, which it installed on a test site last summer.
The low radiation of the turbine was confirmed by the Dutch Institute for Radio Astronomy (ASTRON), via a highly complex measuring procedure using low-frequency array (LOFAR) antennas and their own technology, Nordex said.
That enabled the 172MW order for the DMO wind farm in the close vicinity of the central antenna field of LOFAR – a Europe-wide network of thousands of highly sensitive radio antennas researching the universe.
"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,” Nordex chief sales officer Patxi Landa said.
“Now we can offer our N131 turbines for other projects with similarly demanding requirements regarding minimal electromagnetic radiation.”
The order for the three customers Duurzame Energieproductie Exloermond, Raedthuys DDM and Windpark Oostermoer Exploitatie comes with a 25-year service agreement.
Turbine delivery and installation will start in the second half of 2020.
