"Certification Type" designates to which Standard(s) the applicant is pursuing SWCC certification: IEC 61400-1 (Design), IEC 61400-12-1 (Power Performance) and/or IEC 61400-11 (Acoustics).


"Reference Annual Energy" is the calculated total energy that would be produced during a one-year period with an average wind speed of 5 m/s (11.2 mph).


"Reference Sound Pressure Level" is the sound pressure level (dBA) not exceeded by the wind turbine 95% of the time at a distance of 60 meters from the rotor with an average wind speed of 5 m/s (11.2 mph).


"Reference Power" is the highest point on the certified power curve at or below 11 m/s (24.6 mph). Manufacturers may still describe or name their wind turbine models using a nominal power (e.g. 50 kW E-3120).


"Peak Power" is the highest point on the certified power curve.
