In this study, an analytical model has been developed to predict the performance of coal-fired thermal power plant based on effect of condenser pressure. The current model has been developed to anticipate the energy and exergy-based behavior of the coal-fired power plants. This study deals fundamentally with the coal-fired power plants based on exergy analysis. The objective of this study is to analyze the effect of condenser pressure that leads to the highest exergy destruction. The plant’s thermal efficiency was determined to be 44% with a net efficiency of 31% for a gross power output of 594.25 MW. Increasing the condenser pressure lead to decreases energy and exergy efficiency. It was observed that operating the coal-fired power plant yields a positive response regarding exergy losses.
