windtest north-america has been providing data and analysis for clients in North America for the past 15 years, and our parent company, windtest grevenbroich, has been doing so for the global wind energy industry for more than 25 years.

We engage at multiple points in the process, from turbine manufacturers’ R&D to site selection, on-site operation to seamless transfer of power onto the grid. 

We’ve completed thousands of projects for small wind turbines to utility-scale operations, including more than 100 in North America, involving tens of thousands of megawatts of installed capacity. In addition, our committment to high quality goes beyond the technical aspects of the work we do; we're also really good to work with.
