Fraunhofer IWES ensures investments in technological developments in the field of wind energy through its validation services. By operating large test rigs, it accelerates the market introduction of innovative products, enhances certification processes, and increases planning security by using state-of-the-art measurement techniques. Fraunhofer IWES employs around 220 scientists and administrative staff and 80 students at five sites in Bremerhaven, Hanover, Bremen, Hamburg, and Oldenburg. In 2018, the operational budget was €22 million.
Today, Fraunhofer IWES operates test rigs for rotor blades, nacelles, support structures, rolling bearings, and main shafts – this has been possible thanks to continuous public funding right since the institute’s founding in 2009.
