Fraunhofer Institut IWES


Fraunhofer IWES ensures investments in technological developments in the field of wind energy and

hydrogen technology 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 250

scientists and administrative staff and more than 100 students at five sites: Bremerhaven, Hanover,

Bremen, Hamburg and Oldenburg. In 2019, the operational budget has been 28 million Euros.


Today, IWES operates test rigs for rotor blades, nacelles, support structures, rolling bearings and

main shafts. With an electrolyser test field, the methods for hydrogen production at Fraunhofer IWES

can be systematically tested and extensive synergies can be created. All of this has been possible

thanks to continuous public funding right from the start in the founding year 2009.The testing

spectrum was developed in cooperation with industry leaders, who were involved from the design

phase right up to commissioning. This approach made sure that the test rigs and measurement

equipment comply with actual industry needs. These assets combined with the methodological

competence of its employees make Fraunhofer IWES a preferred research and development partner

for companies all around the globe. By participating actively in international committees and

associations, the institute contributes to technology development and quality assurance within the

wind industry.



The quality, occupational health and safety and environmental management system of Fraunhofer

IWES is certified according to DIN EN ISO 9001, DIN ISO 45001 and DIN EN ISO 14001.



The accredited laboratory with the areas rotor blade, material laboratory and field measurements is

accredited by the German Accreditation Body (DAkkS) according to DIN EN ISO/IEC 17025 with a

flexible scope of accreditation Category III* and Category I**.


IECRE approval

The IECRE committee has approved the accredited laboratory for testing of rotor blades as per IEC

61400-23. The IECRE system (IEC System for Certification to Standards Relating to Equipment for Use

in Renewable Energy Applications) offers an internationally valid certification system for products

and services in the field of renewable energy. With this Fraunhofer IWES also meets the highest

safety requirements at the same time.
