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) www.nrel.gov – U.S. D of E’s laboratory for renewable energy R&D• Test documentation at http://seaforthenergy.com/aoc- 1550/certifications/
Certification - Purpose• Allows SWT product to qualify for Feed-in Tariff (FiT)• Consumer protection• Financial institutions demand certification – or do they mean standards?
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.
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
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.

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
