 In this paper, Exergy and Exergoeconomic analysis of 600MW Thermal Power Plant is carried out. The energy and exergy at input and output of each component is calculated and specified with the help of data taken from the plant. The first and second law efficiency for each and every component of thermal power plant is calculated separately. The analysis shows that maximum amount of exergy destruction occurs in the boiler, which is around 42% of the total exergy produced and maximum energy loss occurs in the condenser which is 68.79%. The exergoeconomic factor is calculated for steam generator, turbine and condenser and it is found out to be 0.45, 0.81 and 0.41 respectively. A low value of the exergoeconomic factor and large percentage of exergy destruction i.e. (42%) in boiler implies that it is worth investing in boiler in terms of design or technical changes. Finally, the components are found where there is scope of improvement or having high exergy destruction with the help of Improvement Potential and maximum Improvement Potential is found out for the boiler which is around 92% of the overall improvement potential of the plant.
