Abstract

IEC 61400-15-1:2025 defines a framework for assessment and reporting of the wind turbine suitability conditions for both onshore and offshore wind power plants. This includes:a) definition, measurement, and prediction of the long-term meteorological and wind flow characteristics at the site;b) integration of the long-term meteorological and wind flow characteristics with wind turbine and balance-of-plant characteristics;c) characterizing environmental extremes and other relevant plant design drivers;d) addressing documentation and reporting requirements to help ensure the traceability of the assessment processes.This document is framed to complement and support the scope of related IEC 61400 series by defining environmental input conditions. It is not intended to supersede the design and suitability requirements presented in those documents. Specific analytical and modelling procedures as described in IEC 61400-1, IEC 61400-2, IEC 61400-3-1 and IEC TS 61400-3-2 are excluded from the scope of this document.
