  1. 1. SEAFORTH ENERGY Standards, Testing & @seaforthenergy
  2. 2. SEAFORTHENERGY Standards
  3. 3. Standards• IEC61400-2• THE international standard for small wind turbine (SWT)• IEC = International Electrotechnical Committee• IEC61400-2 includes the definition of ‘class’
  4. 4. Definition of SWT Rated power of 50kW Swept area 200 sq. m
  5. 5. SEAFORTHENERGY Independent Testing
  6. 6. Testing• Some wind turbines are “designed & built” to the IEC61400- 2 standard• Some wind turbines are also independently tested to the IEC61400-2 standard• Seaforth Energy has had the AOC15/50 independently tested to the IEC61400-2 standard – to Class II• National Renewable Energy Laboratory (NREL) – U.S. D of E’s laboratory for renewable energy R&D• Test documentation at 1550/certifications/
  7. 7. Independently Tested
  8. 8. SEAFORTHENERGY What is meant by Class?
  9. 9. Definition of ‘Class’
  10. 10. Existing Wind Turbines Proven Energy EvanceIndependently tested to class II Independently tested to class II
  11. 11. SEAFORTHENERGY Certification
  12. 12. Certification - Purpose• Allows SWT product to qualify for Feed-in Tariff (FiT)• Consumer protection• Financial institutions demand certification – or do they mean standards?
  13. 13. Certification -Detail • Only SWTs are eligible for testing towards certification • Certification for SWTs uses the IEC61400-2 standard • Existing certificates are: – UK – Microgeneration Certification Scheme (MCS) – North America – Small Wind Certification Council (SWCC)* • SWT ‘class’ depends on: – Duration testing: • Test duration • Wind speeds during testing • Test site* Active for consumer protection but not yet FiTs. This is to change soon particularly in Nova Scoatia.Concentrate now only on MCS.
  14. 14. 50kW Wind Turbines & Certification• 50kW wind turbines are not SWTs!• Why? – Swept area is greater than 200 sq. m. • Therefore not eligible for MCS test and certification – More than 50kW! • Total Installed Capacity = 55kW • Declared Net Capacity = 54kW
  15. 15. AOC15/50 and Certification• The AOC15/50 currently has no certification!• Why? – UK FiT applies only to SWTs• However . . .• AOC15/50 is “eligible” for testing to SWT certification!• Why? – Swept area is less than 200 sq. m.
  16. 16. SEAFORTHENERGYSmall Wind Certification Council (SWCC)
  17. 17. AOC15/50 & SWCC
  18. 18. AOC15/50 and SWCC• SWCC uses the IEC61400-2 standard
  19. 19. SWCC Status • Testing nearly complete: – Design Evaluation – on-going – Power & Performance - on-going – Duration - complete – Acoustic – complete – Safety & Function - complete • SWCC certification expected around May/June • Very expensive • Very lengthy
  20. 20. AOC15/50, SWCC & ‘Class’• SWCC duration testing saw insufficient Class I wind speeds
  21. 21. SEAFORTH ENERGYMicrogeneration Certification Scheme (MCS)
  22. 22. AOC15/50 and MCS• Testing to MCS commences after SWCC.• TUV-NEL• Assume only power & performance and acoustic testing will be required.• If correct MCS will certify AOC15/50 to Class II!
  23. 23. AOC15/50 and MCS• MCS uses the IEC61400-2 standard
  24. 24. SEAFORTHENERGY Summary & Action Discussion
  25. 25. Discussion Points• AOC15/50 already independently tested to IEC61400-2• AOC15/50 already independently tested to class II• MCS not required to qualify for UK FiT• SWCC certification to class II expected soon• MCS certification to class II expected early 2014• Redo SWCC duration testing to class I• TUV-NEL perform duration test to include class I winds
  26. 26. Isle of Luing
  27. 27. Alaska Seaforth Energy warrants the AOC15/50 to up to annual average wind speeds of 9 m/s.
