Wind Energy Resource Atlas of the United States Table 1-1 Classes of wind power density at 10 m and 50 m(a).

10 m (33 ft) 50 m (164 ft)

Wind Power Wind Power Density Speed(b) m/s Wind Power Density Speed(b) m/s Class* (W/m2) (mph) (W/m2) (mph) 1 0 0 0 0 100 4.4 (9.8) 200 5.6 (12.5) 2 150 5.1 (11.5) 300 6.4 (14.3) 3 200 5.6 (12.5) 400 7.0 (15.7) 4 250 6.0 (13.4) 500 7.5 (16.8) 5 300 6.4 (14.3) 600 8.0 (17.9) 6 400 7.0 (15.7) 800 8.8 (19.7) 7 1000 9.4 (21.1) 2000 11.9 (26.6)

(a) Vertical extrapolation of wind speed based on the 1/7 power law.

(b) Mean wind speed is based on Rayleigh speed distribution of equivalent mean wind power density.

Wind speed is for standard sea-level conditions. To maintain the same power density, speed increases 3%/1000 m (5%/5000 ft) elevation.

  • WEB NOTE: Each wind power class should span two power densities. For example, Wind Power Class

= 3 represents the Wind Power Density range between 150 W/m2 and 200 W/m2. The offset cells in the first column attempt to illustrate this concept.
