Exergy and energy analyses were carried out in each component to study the effect of compression ratio, ambient temperature, and load on energy losses and exergy destruction. The highest exergy destruction occurred in the combustion chamber and the lowest exergy destruction occurred in the compressor. Also, the maximum thermal efficiency of the gas turbine unit and second law efficiency are 33.77% and 32.25%, respectively. The peak load of the selected power station is 65 MW. This study reveals possible areas of focus to improve performance of the power plant in the future.
