Grevenbroich, September 2023

It was 25 years ago, on 1 June 1998, that we put the DeWind D4 prototype into operation on our test site south of Grevenbroich.

(Grevenbroich, October 2021) 25 years ago, on October 8, 1996, windtest grevenbroich gmbh was founded. Now, on the occasion of this anniversary, it’s time to celebrate and look back with excitement and pride on a long and successful company history as well as on 23 years of test field operation near the company headquarters.
