Certification of wind turbines involves three distinct steps: establishing hardware performance standards, conducting tests, and operating an independent certification body.  All parts are necessary to implement certification. However, ICC-SWCC only conducts the third step.


What ICC-SWCC Does

  • Certify Small and Medium-Sized Wind Turbines: ICC-SWCC is an independent certification body created to serve the North American market. ICC-SWCC certifies wind turbines that conform to industry standards.
  • Issue Consumer Labels: For small wind turbines, ICC-SWCC issues easy-to-understand labels for Rated Annual Energy Output, Rated Power, and Rated Sound Level. The label also confirms that the turbine meets durability and safety requirements. As turbines are certified, ICC-SWCC publishes Power Curves, Annual Energy Performance Curves and measured sound pressure levels for each model certified.



  • Establish Standards: The American Wind Energy Association (AWEA) has adopted the Small Wind Turbine Performance and Safety Standard establishing a common North American framework for reporting wind turbine energy and sound performance.
  • Conduct Tests: ICC-SWCC does not conduct tests, but verifies and certifies test results submitted by approved testing organizations. Certification applicants test their turbines to the AWEA Standard.
  • Certify Towers or Foundations: Under the AWEA Standard, towers and foundations are not part of the certified system.


Through active ongoing participation in technical committees for the AWEA Standard,  and the IEC Standards, ICC-SWCC is playing a key role in helping to update and achieve international harmonization of standards, testing and certification. ICC-SWCC is working diligently with other wind certification programs in Europe, Asia and North America to minimize the differences between country-specific requirements in order to address a well-recognized market barrier.


ICC-SWCC Certification Is

  • An independent confirmation by an accredited certification body that the wind turbine has been tested and designed according to the requirements of the AWEA Standard.


ICC-SWCC Certification Is Not

  • An assertion that a wind turbine is durable, reliable, quiet, loud, safe, efficient, good, bad, failure-proof or perfect.
  • Provided by AWEA.
