Fraunhofer Institute for Wind Energy Systems

What Fraunhofer Institute for Wind Energy Systems does

Fraunhofer IWES is a non-profit applied research institute — a constituent (non-separately-incorporated) entity of the Fraunhofer-Gesellschaft — headquartered in Bremerhaven, Germany, focused on validating wind energy and hydrogen technologies. Founded in 2009 and operating from 7+ sites across Northern and Eastern Germany (Bremerhaven, Hannover, Hamburg, Bremen, Oldenburg, Leuna, Görlitz), it operates globally one-of-a-kind physical test infrastructure including the 115m+ Rotor Blade Test Rig, the DyNaLab Dynamic Nacelle Testing Laboratory, the Test Center for Support Structures (TTH) in Hannover, the HiL-GridCoP test bench, the 80 MVA Mobil-Grid-CoP mobile grid emulator, three industrial-scale Hydrogen Labs, an OWA Stage 3+ certified Floating Lidar Buoy, a Dual Doppler Wind Radar, and an ultra-high-resolution multichannel seismic survey system.

The institute generates revenue through a mix of public research grants (German federal ministries BMBF/BMWE, EU programs including CETP and Horizon), commissioned contract research and measurement campaigns with wind OEMs (Vestas, GE Renewable Energy, Adwen), utilities and TSOs (Iberdrola, 50Hertz, Enefit) and government agencies (notably the BSH), fee-based use of its unique test infrastructure for certification and type testing, IP licensing from a growing patent portfolio, and a nascent SaaS-style distribution of validated digital tools via the IWES Digital Hub platform launched in January 2026. Its customer base spans wind turbine OEMs, offshore wind developers and utilities, federal regulators, hydrogen / PtX value-chain players, and academic and applied-research consortium partners (SINTEF, Equinor, TÜV SÜD, Equinor, Fraunhofer IMWS, Fraunhofer IKTS, KIER, etc.).

Fraunhofer IWES positions itself as a neutral, independent validation partner for the German and European energy transition. Its strategic posture over 2022–2026 has been to vertically integrate the wind-to-hydrogen value chain (three new Hydrogen Labs in 2022, HiL-GridCoP, electrolyser control research), to extend its measurement authority (Stage 3 / Stage 3+ Floating Lidar certifications, Dual Doppler Radar), and to begin productising its research outputs through the IWES Digital Hub software platform and an expanding patent portfolio covering rotor-blade testing, large-bearing testing, repair methods and surface-machining devices.

Core offering

Fraunhofer IWES conducts applied research and provides large-scale testing, validation, and certification services for wind energy and hydrogen systems. It operates unique test infrastructure for rotor blades, drivetrains, grid integration, and offshore wind resource assessment, delivering R&D services and digital tools to wind OEMs, utilities, project developers, and public authorities.

Product overview

Fraunhofer IWES does not offer a single SaaS product but instead operates a research-institute service portfolio combined with a portfolio of physical test infrastructure, measurement systems, and a growing set of digital tools. Its core offering is organized around four service areas: (a) electrical components and system validation supported by facilities such as the 115m+ Rotor Blade Test Rig, DyNaLab, HiL-GridCoP and the Mobil-Grid-CoP 80 MVA mobile grid emulator; (b) electrolyzer validation and qualification through the Hydrogen Lab Bremerhaven, Hydrogen Lab Leuna, Hydrogen Lab Görlitz and the HIPE-LAB; (c) testing and system validation of large mechanical components using test rigs such as the Großlagerprüfstand and TTH Test Center for Support Structures; and (d) reliability, monitoring and yield analysis including the O&M services supported by the IWES Wind-Lidar-Boje, Dual Doppler Wind Radar, Ultra High Resolution Seismic System and Integrated Quantitative Ground Model. Its digital layer is centered on the IWES Digital Hub platform (with the first service GRIDSLI), supplemented by stand-alone software tools such as COAST and OffshoreTimes, and by research projects that translate AI methods (e.g., the WindKI project with LATODA and the Operations Ontology for fault diagnosis) into wind-turbine applications. The rotor-blade, sub-surface investigation, wind measurement, and overall system measurement and simulations service lines tie these physical and digital capabilities together into an applied-research offering for wind energy and hydrogen technology.
