As you may have heard, the U.S. Department of Energy has issued a guidance memo on quality assurance to 17 federal agencies encouraging that public funds be provided only for wind turbines that have been tested and certified for safety, performance, function, and durability. This memo applies to distributed wind turbines (small and medium turbines generally under 1MW) and will help ensure that taxpayer funds support turbines that meet performance and safety standards. Fifteen turbines up to 100kW are fully certified in the US; nearly thirty more are in the process of certifying.
The Clean Energy States Alliance, through its Interstate Turbine Advisory Council (ITAC), recommends that state agencies and utilities provide incentive funding for certified turbines that meet ITAC’s additional responsible business practices criteria. ITAC maintains a list with 11 turbines that meet its standards: http://www.cesa.org/projects/ITAC/itac-unified-list-of-wind-turbines/
