Gas turbine efficiency and power output are strongly dependent on the inlet air condition. Thus, several authors proposed the use of different inlet air cooling systems. Such systems include, as examples, spraying water in the inflow air stream or air cooling through a chiller during GT operation. In the latter case, it is possible to operate the chiller at night time, taking advantage of the remarkable price gap between peak and off-peak hours. A parametric analysis of such a system is presented, focusing on the effect of price gap, chiller and storage design parameters and climatic conditions on the optimal sizing of the plant. Both the gas turbine performance changes, due to the different inlet conditions, and thermal losses related to the storage system are taken into account. The economic return of the system is evaluated through the year-round integral of gas turbine fuel consumption and chiller electricity requirements, for given scenarios of electricity price tag, ambient temperature and humidity profile. For different boundary conditions (market constraints and climate) the optimal configurations are identified and discussed.
