The "boom" in gas-fired power plant construction of the late 1990s and early 2000s led to capacity margins exceeding 20 percent throughout much ot North America. This capacity glut, combined with soaring natural-gas prices, drove many existing combined-cycle plants off-line for months at a time-essentially mothbailing them until brighter economic conditions might return. Those fortunate to run at all typically ran at unusually low capacity factors, with daily start/stops becoming the norm for formerly baseload facilities. By 2006, moderated natural gas prices and diminished capacity margins-helped by the "bust" in new construction and a sweltering summer-enabled many combined-cycle plants to return to service. In accounting offices, that turnaround means a potentially profitable year.
