Institute Profile

Fraunhofer IWES has two main thematic areas, wind energy (northwest) and energy system technology (Kassel). It was established in 2009 as a merger of the former Fraunhofer Center for Wind Energy and Maritime Engineering CWMT in Bremerhaven and the Institute for Solar Energy Technology ISET in Kassel. 

IWES in Kassel mainly researches on energy system technology for the integration of renewable energy such as wind, solar and bio energy into supply structures. The current focus is on the transformation of the German energy system.

Under the leadership of Prof. Dr. Clemens Hoffmann, a staff of 310 scientists, engineers, non-technical staff, and students is employed at the IWES branch in Kassel. The annual budget is approximately 20 million euros.

Key Area of the Future: Energy System Technology


The further expansion of regenerative energies and consequent replacement of conventional generating capacity requires sustainable reorganization of the energy supply structures by using modern power electronics and the networking and coordination of genera­tors, grids, storage systems, and consumers. The objective of future R&D work must be to design supply structures such that grid stability and reliability of supply remain guaranteed for the situation with a growing number of fluctuating energy generators, and even without large capacity reserves.
