Abstract: The results from the energy audit from KOTHAGUDEM Thermal Power Station, Andhra Pradesh have been presented in this paper. Study of heat transfer, effectiveness, proportioning of heat and pressure drop in the heat exchangers of water steam circuit, study of auxiliary power consumption; overall performance evaluation such as gross and the net overall Efficiencies, Boiler Efficiency, Boiler Pump Efficiency, Air Compressor Efficiency, Evaporation Losses and Blow Down Losses of Cooling Tower etc. Results from such a study at 500MW Power Plant are presented in this report. The Variable Speed Drive system of Boiler feed pump system replaces Hydraulic Coupling method which is energy efficient and the energy conservation technique of using Air compressors improve the efficiency of thermal Power Plant.
