Abstract: A recent study completed by the Pacific Northwest National Laboratory evaluated the economics of several alternative combustion turbine inlet air cooling (CTAC) systems applied to different types of power plants and various operating conditions. The principal parameters investigated were chiller type, storage type, inlet air temperature, combustion turbine application, power plant operating schedule, and climate. About 3500 combinations of these parameters were evaluated to determine the capital cost per incremental peak power output and the net present value of the investment. This paper summarizes the study, identifying the preferred inlet air cooling technologies for simple-cycle industrial turbine applications, with an emphasis on the affect of climate on CTAC technology selection and economics. Five cities representing distinct climates (Houston, Minneapolis, Nashville, Phoenix, and San Francisco) were evaluated, which should serve as reasonable proxies for much of the world as well as most of the United States.
