>I'd be interested in where you got the terrible efficiency data from.
most peaker plants use single cycle gas turbines, which have fairly low efficiency. it's usually in the low 30s for newer plants depending if the plant has heat exchangers to cool the incoming air.
there are also peaker plants that use reciprocating engines, these ones have even worse efficiency.
standard combined cycle gas thermal plants have a second cycle that uses the waste heat from the first cycle to increase the efficiency; in this case it's between 40% and 60%.
