Common sense isn't.
The power curves were taken from
Vestas' (archive, 2006) wind turbine product descriptions.
The curve at left is for the V47-660 kW model, and the curve below is for the V80-1.8 MW model.
The power curves were approximated by polynomial curve fits.
No adjustment is made for location or height above ground level of wind speed measurement
(which would potentially increase calculated power).
An adjustment is made for air density change due to altitude, temperature and humidity.

All 3 V47 turbines and all 15 V80 turbines are assumed to be operating at the same power
for total plant power calculations.
TVA's original goal of 6 million kWh per year for the first 3 turbines is from published newspaper articles and on
their sign at the site.
This initial goal was extrapolated based on total rated power to get the 87.8 million kWh
estimate for all 18 turbines:

| Quote of the moment |
| We shall make mistakes, but they must never be mistakes which result from faintness of heart or abandonment of moral principles. I remember that my old school master Dr. Peabody said in days that seemed to us then to be secure and untroubled, he said things in life will not always run smoothly, sometimes we will be rising toward the heights and all will seem to reverse itself and start downward. The great thing to remember is that the trend of civilization itself is forever upward. |
| ~ Franklin D. Roosevelt (1882–1945), U.S. president. FDR Speaks authorized edition of speeches, 1933-1945 (recordings of Franklin Roosevelt’s public addresses), side 12, fourth inaugural address (Jan. 20, 1945), ed. Henry Steele Commager, Introduction by Eleanor Roosevelt, Washington Records, Inc. (1960). The President reminded Americans that neither winning the war nor making the peace would be easy or without errors, but that they had to keep in mind the broader objectives and the need to try for the best results. ~ |
