Consumed and Net Generation KW Data for TVA's Wind Power Plant

The following information was requested under the Freedom of Information Act, on April 7, 2002.

Data for consumed KW and net generation KW, versus time, from beginning of operation to current date.

The following response was released by TVA on December 2, 2002. In essence, it was an admission that they do not keep thorough records, and a refusal to provide the requested information, which is available, under the pretense that they already provided the information.

"With regard to the consumed KW, we do not track station consumption, therefore, we have no records responsive to this part of your request. With regard to the net generation data, on May 16 I sent you copies of the Green Power Switch newsletters (archive, 2002) which contain the net generation data."

Other utilities, such as Wisconsin Public Service Corporation, track and conveniently publicize very thorough details for both consumed (archive, 2009) KW and net generation KW for similar wind power plants. Why doesn't TVA?

It is interesting to see that consumed power can be as much as about 1-2% of rated power, or about 4-8% of expected average power based on 25% capacity factor. In a quick look at Wisconsin PSC's data, I observed up to about 12 KW for one turbine on December 8, 2002. Therefore, when the wind plant is not producing power due to low wind or other problems, it may actually be increasing demand for conventional power plants and their associated emissions, at a rate of up to about 8% of expected average wind plant power. This is not a huge amount, but it is also not an insignificant amount of additional air emissions due to the wind power plant.

TVA already provides detailed production data (archive 2002) for their solar power stations (although perhaps with buggy javascript, and best viewed with iE). Why does TVA not provide similar detailed data for the wind power plant?

Quote of the moment

You doctors who more execution have done With powders and bolus with potion and pill, Than hangman with halter, or soldier with gun Than miser with famine; or lawyer with quill; To kill us the quicker, you forbid us malt liquor, Till our bodies consume and our faces grow pale; But mind it, what pleases, and curse all diseases Is a comforting dose of good ale!

How intermittent is power production at TVA's Wind Power Plant?

How much power does the plant consume (especially when not producing)?

TVA can't or won't say
