1. The Scale of Wind Power Per US DOE (US Department of Energy)  According to the US Department of Energy, Wind & Hydropower Technologies Program, wind turbines fall in two categories:  Utility-scale turbines range in size from 100 kilowatts to as large as several megawatts. Larger turbines are grouped together into wind farms, which provide bulk power to the electrical grid.  Single small turbines, below 100 kilowatts, are used for homes, telecommunications dishes, or water pumping.

6. Small Wind Growth “Small wind” defined as ≤ 100kW 25 MW installed in U.S. in 2010, making 179 total MW in U.S. Significant shift away from micro and off-grid systems to larger, grid- connected units 30% federal tax credit 30 states with small wind incentives 1500 full-time jobs in small wind

7. On-grid vs. Off-grid trends The U.S. market experienced a pronounced shift to larger, grid-connected systems. Combining off-grid and on-grid sales, the average unit size has increased more than three-fold since 2007 (from 1.1 kW in 2007 to 3.3 kW in 2010).

8. 2010 Small Wind Size Trends

9. Small Wind Manufacturers The top three U. S. manufacturers in terms of 2010 capacity sales were Northern Power, Southwest Wind Power and Bergey Windpower. The average installed cost of small wind turbines sold in the U.S. in 2010 was $5,430/kW 9 of the top 10 models sold in the United States are grid connected. 9 of the top 10 are a three-blade design, 10 of 10 are horizontal axis turbines

10. Small Wind Workforce 3 of top 5 small wind companies are American Turbine manufacturing, tower manufacturing, transportation, installation, and education 30% of a turbine’s total cost is installation, most often involving local contractors

11. New for 2010-2011 2010: Small Wind Certification Council 2010: NABCEP Small Wind Installer Credential 2011: National Electric Code Article 694 for small wind generators

12. Small Wind Certification Council Rated Annual Energy: assumes a universal, constant wind speed of 5m/s, a pure Rayleigh wind distribution (weibull k = 2) and gives a value for kWh/year. Rated Sound Level: Value will not be exceeded 99% of the time, assumes a 5m/s wind, rayleigh distribution, and that the observer is 60m from the rotor. Gives a value in decibels. Rated Power: Power output at 11m/s at standard sea-level conditions.
