December 2012


Recently, SWCC issued our third full certification. With SWCC certifications representing a significant share of the North American small wind market, our certification ratings and labels are allowing easier comparison shopping, aiding incentive programs with setting payment levels, and leading toward national requirements.


SWCC continues to improve our certification process. This newsletter, we announce new certification services for medium wind turbines.  These certifications provide the same assistance to consumers and funding agencies as SWCC small wind certifications. 


As always, I'm available if you have questions or comments about SWCC activities.


Best wishes for a happy holiday season!

Evance R9000 Fully Certified   

Evance R9000 On December 18, 2012, SWCC granted full certification of the R9000 from Evance Wind Turbines. The Evance 9000 is designed and manufactured in the UK and has also achieved certification according to the Microgeneration Certification Scheme using BRE Global as the certification body. SWCC has signed a reciprocity agreement with BRE Global which enabled us to use much of the work conducted in the UK for granting our own certification to AWEA Standard 9.1-2009. The Evance R9000 is a 3-blade, upwind, horizontal axis wind turbine with a swept area of 23.8 m2. The AWEA Rated Annual Energy is 9,160 kWh, AWEA Rated Sound Level is 45.6 dB(A) and the AWEA Rated Power is 4.1 kW at 11 m/s. The SWCC Consumer Label, Certificate and Summary Report can be found here.

SWCC Offers Medium Wind Turbine Certification     

Medium Wind Turbine

State incentive programs and consumers are increasingly looking for certification of the turbines they purchase. For turbines with swept areas larger than 200 square meters, the current path to certification is via the international standard IEC 61400-1 which is seen as more appropriate for large, multi-megawatt turbines. Work is underway to develop a medium wind standard similar to the AWEA and BWEA Small Wind Turbine Standards. Development and adoption of this new standard will take time. In the meantime, medium wind manufacturers can certify the acoustics and power performance of their turbines. There is industry consensus that certification of these two performance tests will remain a requirement in any proposed new medium wind standard. This interim step will provide consumers with some assurance of the performance of these turbines, while a standard for full certification is developed.


Agencies such as the Interstate Turbine Advisory Council (ITAC) and the New York State Energy Research and Development Authority (NYSERDA) have established incentive eligibility language for medium wind turbines requiring certified power and acoustic test reports along with either a Design Evaluation to IEC 61400-1 OR a demonstration of a successful fleet of turbines operating in the field. To help manufactures of medium wind turbines conform to these requirements, SWCC is now offering, for turbines with a swept area greater than 200 square meters, the service of certifying Power Performance test results per IEC 61400-12-1 and Acoustic test results per IEC 61400-11. Please contact us if you are interested in these new services.

UL6142 Published   

In September 2011, in cooperation with the American Wind Energy Association (AWEA), Authorities Having Jurisdiction (AHJs), small wind turbine manufacturers and other industry stakeholders, UL formed a Standards Technical Panel (STP) to develop a new electrical safety standard for small wind turbines. The process is now complete and ANSI/UL 6142 Ed. 1 - Standard for Safety for Small Wind Turbine Systems was published as an American National Standard on November 30, 2012. The 2014 National Electrical Code (NEC) will reference this new standard for small wind turbines and small wind turbine manufactures are encouraged to start working on UL6142 certification now that the standard has been adopted.


UL defines a small wind turbine as "turbines where a user or service person cannot or is not intended to enter the turbine to operate it or perform maintenance."


Certification to AWEA Standard 9.1-2009 is a prerequisite for UL6142 certification as stated in section 1.2: "It is intended that the electrical subassemblies that address power transfer control and protection functions evaluated per this document are to be coordinated with the mechanical and structural limitations specified in AWEA 9.1, Small Wind Turbine Performance and Safety Standard..." Please contact us if you have questions about UL6142 certification.

Why Turbine Certification is Important    

With SWCC certification, manufacturers can gain increased mainstream credibility and boost the small wind industry's overall reputation among investors, consumers, policy makers. Inclusion on the SWCC's premier listing of certification ratings allow consumers to compare products and funding agencies to gain greater confidence that small turbines installed with public assistance have been tested for safety, function, performance and durability and meet requirements of consensus standards. Certification helps prevent unethical marketing and false claims, ensuring fair competition among suppliers.


Incentives for small wind turbines have been impacted by the lack of certification. Inaccurate power performance claims led to suspension and termination of the California Energy Commission (CEC) Emerging Renewables Program. Field failures of non-certified turbines led to delays and scaling back of rebate programs in New Jersey and other states. These developments have affected the industry greatly and highlight the importance of certification.


Several U.S. incentive programs are now requiring certification for small wind turbines to become or continue to be qualified to receive funding. For a summary see SWCC's  Incentive Eligibility page and Links to Incentive Programs that are requiring or expecting to require certification.


Manufacturers of small wind turbines are active globally where incentives result in strong markets, particularly in the UK. SWCC has signed reciprocity agreements with three UK certification bodies that are actively certifying small wind turbines for the Microgeneration Certification Scheme (MCS). These agreements enable us to use work from the other party when granting our own certification. This system of 'test once and certify in multiple areas' saves small wind manufacturers time and money as they pursue certification and thus incentive eligibility in both the UK and U.S. markets.


With prominent visibility and known for diligent review of applications, SWCC is positioned as the "go to" source for certified turbine ratings. All small wind manufacturers, even those who have completed testing and certifications elsewhere, are encouraged to complete the SWCC process for listing on our certified turbines table and enhance your status in the industry.
