Abstract Gas turbine power plants are increasingly used worldwide, as one of the most interesting options in electricity generation. Therefore, these types of plants have been widely studied, and as a result the negative effects on their output power and thermal efficiency have been known when operating in atmospheric conditions exceeding ISO conditions (15 °C, 60% RH). For this reason, different technologies and methodologies have been implemented that modify the cycle, aiming to increase the output power and improve the thermal efficiency. Unfortunately, the lack of operational parameters of this kind of system limited its characterization, sizing and implementation of strategies to improve its performance. Advanced exergetic and exergoeconomic analyses have been applied in the study. In order to effectively locate the sources of irreversibilities, their costs and the true potentials of
