What International Wind Engineering does

International Wind Engineering S.A. is a privately held Greek consulting and engineering firm founded in 2002 that delivers accredited wind energy services across the full project lifecycle. Its core service portfolio spans development-phase work (energy yield assessment, due diligence, wind farm design, feasibility and site suitability studies, environmental assessment, and project licensing), operational-phase work (asset management, wind farm operational monitoring, technical inspections, construction monitoring), and testing-and-calibration services (EN ISO/IEC 17025:2017 accredited instrument calibrations, IEC 61400-12-1 power curve measurements, and wind potential measurements). The firm is a full member of MEASNET and holds E.SY.D. accreditation (Certificate No. 547), enabling it to issue bankable technical assessments for project finance transactions.

Underlying technology rests on three pillars: proprietary MultiWind software (International Wind Engineering®) for parallel multi-station wind data analysis, spatial wind distribution assessment, and Measure-Correlate-Predict (MCP) analysis using long-term datasets; accredited closed-loop wind tunnel calibrations performed in partnership with the National Technical University of Athens; and a hardware offering that includes ZX 300 Wind Lidar (DNV-accepted Stage 3 Bankable), meteorological masts, high-precision measuring instruments, and PV modules. The firm also uses WindPRO Software alongside MultiWind.

The business model is professional services on a custom, contact-based pricing structure delivered through direct enterprise sales. Revenue streams are project-based consulting, operational monitoring engagements, and accredited testing/calibration work, supplemented by equipment sales. Customer segments include wind energy investors, financial institutions, wind farm operators, and project developers; named clients include Vestas, Siemens Gamesa, General Electric, Hellenic Petroleum, PPC Renewables, Aquila Capital, EY, and Ixion. Geographic footprint is led by Greece — where the firm claims a 28% market share and 9+ GW / 340 wind farms of cumulative engagement — with stated expansion into Cyprus and an international scope. The company operates without disclosed external capital, subsidiaries, or M&A activity.
