  • Great interdisciplinary competence of all employees
  • Close links with universities and other scientific institutes
  • Firm integration into a worldwide close-knit and growing company network with synergistic effects
  • The largest test field worldwide for wind energy systems used inland

These are the prerequisites that for more than 15 years ensure the success of windtest grevenbroich gmbh (wtg). In the market since 1996, wtg has established itself internationally as an accredited measuring and testing institute and made its name worldwide as an independent evaluator and service provider in the wind energy sector.

The international character of our customer base grew with the development and expansion of the wind energy infrastructure in more and more countries. Today we receive assignments from India, South Korea and the US. The foundation however is the healthy business in Europe. But the secret of success is based on even more factors that belong rather to the so-called "soft skills": friendliness, integrity and reliability of the growing team.

These are indispensable for the data business, since reliable and serious data form the basis for the acceptance and the profitability of investments in wind energy systems. This applies to individuals as well as institutional investors or authorities.

wtg is accredited according to DIN EN ISO/IEC 17025; 2000; a designated Measuring Agency according to § 26 BimSchG (German Federal Immission Control Act) in 15 federal states and a member of MEASNET.
