Dynamic is our strength

Prof. Andreas Reuter, Managing Director Fraunhofer IWES: "The wind energy industry stands for dynamic and change. We at Fraunhofer IWES have been a competent and innovative partner for technology development for more than ten years."




Joint project simulates wind and wave loads on the piles of offshore wind turbines

A joint project between the LUH and Fraunhofer IWES together with other partners is examining the properties of the current and next generation of offshore monopiles in order to develop a reliable calculation method to enable the longest possible service life.



Accelerated testing of rotor blade bearings: Test bench proves successful in regular operation

Fraunhofer IWES has completed a successful series of accelerated tests on rotor blade bearings at the test bench in Hamburg. Within the scope of research and industry projects, bearings were subjected to dynamic endurance tests to increase their reliability.



Fraunhofer IWES is carrying out an offshore survey in the German Baltic Sea for Iberdrola

Fraunhofer IWES is conducting a boulder detection and geohazard survey of 50 wind turbine locations and the associated OSS within the Baltic Eagle offshore wind farm on behalf of Iberdrola S.A. 



VirtualWind III

On Wednesday, November 18th 2020, ORE Catapult is teaming up with Fraunhofer IWES, to host the third VirtualWind online conference focusing on the current challenges for offshore wind energy in the North Sea. This time the focus lies on electrical infrastructure and floating offshore wind. We hope to to welcome you to VirtualWind. 



Optimizing the Grid Characteristics of Wind Turbines

More than € 30 million are set to be invested in expanding the testing infrastructure for electrical systems. In the first phase of the planned expansion, the Fraunhofer IWES is officially putting a new test bench into operation in the scope of the Hil-GridCoP project.



Better together: Biaxial rotor blade testing - New methods for more realistic test loads

Biaxial blade testing is central to future blade test concepts: Fraunhofer IWES combines two fatigue tests (in flapwise and edgewise direction) in one single test. 


What truly defines the “IWES spirit”

Describing the culture of an institute in words is no mean feat. It is often a matter of shared experiences, the development of extraordinary approaches, and a common understanding of the expected level of quality. 

Our work generates a practical added value and turns innovative ideas into reality. Find out more – from our employees themselves.
