Due to insufficient cooling, the output power of gas turbine (GT) power plants in dry areas decreases during the hot summer months. It has been commonly utilised to address this flaw to cool the compressor’s air intake. A GT Brayton cycle connected to a refrigeration cycle offers potential for boosting the output power with a slight drop in thermal efficiency, according to an energy study. A thermo-economics algorithm is created and used to an open cycle Hitachi MS700 GT plant in Yanbu, an industrial city in the Kingdom of Saudi Arabia (located at Latitude 24o05″ North and Longitude 38oE). The increase in output power is dependent on how much the compressor’s air intake is chilled, according to the results (a 12 – 22 K decrease is achieved). Maximum power gain ratio (PGR) for this case study is 15.46 percent, with a negligible loss in thermal efficiency of 12.25 percent. The price of incorporating the air cooling system is also examined, and a cost function is developed that takes into account time-dependent meteorological data, the GT’s and the air intake cooling system’s operational characteristics, as well as other pertinent factors like interest rate, lifetime, and operation and maintenance costs. Different power tariffs are used to assess the benefit of implementing an air conditioning system.
