good post, except -- your terminology is misleading here ...

>>5) Some of the combined-cycle plants in states with low intrastate gas prices (e.g. Texas) can profitably run as baseload capacity. However, most of the combined-cycle and all of the simple-cycle plants act as peaking plants. That means most generate less than 20 percent of nameplate capacity rating.
<<

most peakers have to run close to nameplate capacity -- when they run -- what you mean is capacity factor which is a measure of

actual energy produced / theoretical total that could have been produced

not capacity.

It is not uncommon for peakers to be beneficial and only have an expected capacity factor of less than 10%. If a combined cycle plant doesn't run with an annual capacity factor of greater than 20%, it probably was a malinvestment -- shoulda bought a peaker instead.
