Dry cooling systems tend to be more economical for natural gas combinedcycle plants because the amount of cooling needed is much less per megawatthour than for coal or nuclear plants. More than 15% of operating generating capacity from natural gas combinedcycle plants in the United States use dry cooling technology.
