In responding to changes in electricity demand, there will be changes in the amount of fuel supply, the amount of combustion air supply, and the performance and efficiency of the generator. To overcome the community's demand for high electric power, PJB UPGRESIK has 3 units of PLTGU in block 2 operating, there is a major overhaul in unit 2.2. Due to the frequent use of the generating unit in block 2, the performance of the generator slowly decreases, if this happens it will be overhauled to restore the power plant's performance. In the compressor, Turbine, BWR, SFC and Cycle efficiency in units 2.1 and 2.3 have decreased after Combustor Inspection, in the Compressor efficiency of 16% difference, in Turbine efficiency 4%, in SFC 4%, in BWR 3%, and in Cycle efficiency 12 %, the performance of the 2.3 Turbine gas unit load of 100 MW has better performance than unit 2.1.} }
