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 |
| Our security depends on the Allied Powers winning against aggressors. The Axis Powers intend to destroy democracy, it is anathema to them. We cannot provide that aid if the public are against it; therefore, it is our responsibility to persuade the public that aid to the victims of aggression is aid to American security. I expect the members of my administration to take every opportunity to speak to this issue wherever they are invited to address public forums in the weeks ahead. |
| ~ Franklin D. Roosevelt (1882–1945), U.S. president. Interview with former Secretary of Labor Frances Perkins, University of Illinois, Urbana (Spring 1958). For several years beginning in 1937 the President was determined to convince Americans via his press conferences and public addresses that Nazism and fascism were menaces to the democratic way of life and the very security of the United States. This was the first time that he assigned that task in addition to the members of his administration. This was Perkins’ recollection of what FDR told the Cabinet before the Lend-Lease legislation was to be acted upon by the Congress in 1940. ~ |
