ITAC Unified List of Wind Turbines

Clean energy programs and utilities wishing to use the ITAC list as the basis for incentive or other funding eligibility must be participants in ITAC. Joining ITAC gives members access to the decision justifications for evaluated turbines and detailed product information provided by the manufacturers not found elsewhere. A list of participating incentive programs can be found on the Participating programs page.

Use of the ITAC list of wind turbines by nonparticipating organizations is not permitted.

DISCLAIMER: Neither CESA nor the individual members of ITAC endorses any of the wind turbines contained in this Unified List. This list has been made available to give ITAC-member programs a basis on which to provide their incentives. ITAC makes no claims about any listed turbine’s durability, reliability, safety, acoustic emissions, performance, efficiency, or suitability. Conversely, turbines not included on the list are not implied to be unsuitable or defective in any way.

Small Wind Turbines

The list below contains turbines that have been fully certified to the American Wind Energy Association’s small wind turbine performance and safety standard, version 9.1 (2009) or have met Microgeneration Certification Scheme requirements for small turbines. In addition, these turbines have been fully vetted by ITAC and additionally meet ITAC’s warranty and business performance criteria. Any exceptions are noted below.

New IRS rules for qualifying for the 30% federal investment tax credit require turbines to meet either AWEA 9.1 or IEC 61400-1, 61400-12, and 61400-11. The best way to show conformance to the IRS requirements is through certification. Turbines denoted with a "+" indicate that they meet IRS requirements.
