Abstract: The energy supply to the demand narrowing down day by day around the world, the growing demand of the power has made the ower plants of scientific interest, but most of the power plants are designed by the energetic performance criteria based on the first law of thermodynamics only. The real useful energy loss cannot be identified by the first law of thermodynamics, because it does not differentiate between the quality and quantity of energy. The project on Exergy Analysis was undertaken on Rayalaseema Thermal Power Project located in Kadapa, Andhra Pradesh. The capacity of the plant is 5×210 MW. Energy analysis presents only quantities results while Exergy analysis presents qualitative results about actual energy consumption. The main objective is to analyze the system components separately and to identify and quantify sites having largest energy and exergy efficiency losses .It also presents major losses of available energy at super-heater, boiler and turbine section. Exergy destruction and energy loss comparison charts are drawn for different components. The results are tabulated and graphs are plotted to show correlation between various parameters. This project would also throw light on the scope for further research and recommendations for improvement in the further existing plant
