What sized turbines are eligible for ICC-SWCC’s small and medium wind certification programs?

Small Wind Turbine: Electricity-producing wind turbines with a swept area up to 200 m2.

Medium Wind Turbine: Electricity-producing wind turbines with a swept area greater than 200 m2 and less than 1,000 m2.

What are the benefits of ICC-SWCC certification?

Certification enables consumer comparison of the wide variety of wind turbine products on the market. Funding agencies and utilities will gain greater confidence that distributed wind turbines installed with public assistance have been tested for safety, function, performance and durability and meet requirements of consensus standards. Certification can help prevent unethical marketing and false claims, thereby ensuring consumer protection and industry credibility.

What is the difference between the AWEA Rated Power and a Nominal Power listing for a certified turbine?

Small wind turbines certified to the AWEA Standard are required to publish the AWEA Rated Power in their specifications. This rating is the wind turbine’s power output at 11 m/s (24.6 mph) per its certified power curve. Manufacturers may still describe or name their turbine using Nominal Power. Nominal Power is designated by the manufacturer for descriptive marketing purposes.

What happens to a turbine certification if the manufacturer goes out of business?

Turbine certification is valid so long as the certification renewal conditions listed in the SWCC certification policies are met. Certification must be renewed annually. If ownership of the turbine design changes, a new Certification Agreement must be signed by the new owner to maintain the validity of the certification, per the ‘Change in Ownership’ clause in the SWCC certification policies.
