Anemos

What Anemos does

Anemos Gesellschaft für Umweltmeteorologie mbH is a German environmental meteorology specialist focused exclusively on wind energy services, founded in 1990 by Dr. Heinz-Theo Mengelkamp and headquartered in Reppenstedt near Lüneburg. The company combines accredited site assessment and energy yield studies, TR10 site quality determinations for EEG 2017/2021 compliance, wind measurements (met mast, LiDAR, SoDAR), CFD simulations for complex terrain, and due diligence reviews for wind farm developers, operators, asset managers, and lenders. Its technology stack is built on mesoscale wind modeling (WRF, MM5) downscaled from ERA5, MERRA-2, and NCEP reanalysis, calibrated to observational data through a proprietary "remodeling" methodology, and validated against FINO offshore platforms and 100+ onshore masts.

Anemos monetizes through two complementary streams: project-based professional services (wind/energy yield reports, TR10 site quality certificates, SCADA-based performance analysis, CFD, due diligence, loss calculations) sold via direct consulting engagement, and recurring access to its awis web portal and the multi-region anemos wind atlas family (Germany at 1.35 km and 3 km, France at 3 km, EU at 10–90 km, Scandinavia/Baltic, Poland). The awis tool offers a free demo entry point and integrates energy yield calculations with wake losses, wind/energy yield indices, maps, and a Marktwertatlas for revenue optimization (the latter jointly with enervis energy advisors). The company holds DAkkS accreditation (D-PL-17580-01-00) under DIN EN ISO/IEC 17025:2018 for TR10 determinations and reports assessment experience on more than 35 offshore wind farms totaling 14,000+ MW.

In 2025, Munich-based private equity firm Vidia (Vidia Climate Fund I) acquired a stake in anemos to support digitalization, capacity expansion, and service portfolio growth, while the management team (Lasse Blanke, Martin Schneider, and formerly André Glücksmann) continued leading operations and founder Dr. Mengelkamp remained in a scientific advisory role. The customer base spans most major German wind developers, OEMs, utilities, and financiers (ENERCON, ENGIE, KfW, DKB, LBBW, juwi, ABO Wind, prokon, EnergieKontor, Encavis Asset Management, VERBUND, sowitec, among others). Geographic coverage is concentrated in Germany with documented product expansion into France, broader Europe, Scandinavia/Baltic, and Poland.
