Combined cycle plants may have fewer moving parts than coal plants, but that does not mean that their operations are any easier to analyze. Relatively limited operating experience and sparse data allow beliefs to take root—some well-founded and others less so. This report takes a quick look at three such beliefs and offers some tantalizing, although preliminary, observations on these questions:
- Do higher capacity factors really result in lower non-fuel costs?
- Do older units that start more frequently have higher non-fuel costs?
- Do merchant operators do a better job of cost containment compared to rate base operators?
This is the first in a series of reports exploring fossil generation cost and reliability.
