Table D-6 Distribution of the number of new sites by the difference between the actual and estimated power at 50 m
(164 ft) above ground. The actual power is based on wind data collected at or near the 50 m (164 ft) level. The estimated power is based on data collected at or near the 10-m (33 ft) level and extrapolated to 50 m (164 ft) using the 1/7 power law.
