  1. Standards & Performance Testing  Session Chair: Larry Sherwood Executive Director Small Wind Certification Council AWEA Small and Community Wind Conference December 8, 2010

  2. SWCC certifies Mechanical Strength, Durability, Function & Performance of turbine systemto new AWEA standard NRTLs certify ElectricalSafety of Turbine & Controller (new UL Standards in development) PE certifies Tower & Foundation NRTLs certify Inverter to IEEE 1547/UL 1741 NABCEP certifies the Installer Grid-tie Small Wind Turbine in the US Wired per National Electrical Code (NEC) (new article in 2011)

  3. AWEA Standard • AWEA Small Wind Turbine Performance and Safety Standard (AWEA Standard 9.1 – 2009) • Harmonized with the BWEA Standard (some differences such as acoustics) • Incorporates, with modifications, existing IEC standards for small wind turbines • Written to ensure the quality of the wind turbine can be assessed while imposing only reasonable costs and difficulty

  4. Equipment Eligibility • Per the AWEA standard • Newly manufactured, electricity-producing wind turbines with a swept area up to 200 m2 • 200m2 ~ 16m diameter rotor ~ 65 kW (or less) • Horizontal and vertical axis turbines are eligible

  5. SWCC: Small Wind Certification Council • New independent, third-party certification body to serve North America • Certify that small wind turbines (SWTs) meet the requirements of the new AWEA Small Wind Turbine Performance and Safety Standard • Used as state-level eligibility

  6. SWT Manufacturer(structural analysis) the Standard Test Organization(field testing) Certifies Conformity

  7. SWCC Certification Label • Rated Annual Energy (kWh) • @ annual average wind speed of 11.2 mph (5 m/s) • Rated Sound Level (dBA) • Sound pressure level not exceeded 95% of time with average wind speed of 11.2 mph (5 m/s) at 60 meters from rotor • Rated Power (kW) • @ 24.6 mph (11 m/s)

  8. SWCC Certification Applications Pending 8

  9. Benefits of Certification • Certification labels ease consumer comparison of products • Funding agencies and utilities will 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 can help prevent unethical marketing and false claims, thereby ensuring consumer protection and industry credibility

  10. Standards & Performance Testing • Tim Zgonena, Underwriters Laboratories Public and Regulatory Acceptance – New Developments in Small Wind Codes and Standards • Chris Simpson, Proven Energy Practical Implications of Certification – The UK Experience • Paul Smart, Campbell Scientific Inc. Component Measurements for Assessing Total System Performance of a Small Wind Turbine • Kelly Winder, Saskatchewan Research Council Small Wind Turbine Performance – A Case Study
