N2 - This exergy destruction research was conducted at the Tambak Lorok combined cycle power plant block 2 which has 3 units of Gas Turbine, 3 units of HRSG, and 1 unit of Steam Turbine which operate continuously 24 h with ambient air temperature varying between 24 and 33 ℃. Exergy is the theoretical maximum work that can be obtained when the system interacts to reach equilibrium. The purpose of exergy analysis is to identify the occurrence of exergy annihilation and the occurrence of losses as well as to sort them into the level of importance. The equipment analyzed was CCPP block 2 with an operating pattern of 3-3-1 and GTG-HRSG 2.2 with a variation of ambient temperature inlet compressor 24–33 ℃. The results of the research pattern 3-3-1 block 2 showed that the total exergy destruction in GTG 2.1 was 177.19 MW, GTG 2.2 was 175.92 MW, GTG 2.3 was 182.75 MW, while HRSG 2.1 was 12.99 MW, HRSG 2.2 was 5.49 MW, HRSG 2.3 was 16.399 MW, and STG 2.0 was 44.42 MW. Furthermore, the calculated results of the exergy destruction of GTG-HRSG 2.2 at an ambient temperature of 24 ℃ was 172.72 MW, at an ambient temperature of 28 ℃ was 180.26 MW, and at an ambient temperature of 31 ℃ was 185.23 MW. Thus, it could be concluded that the higher the ambient inlet temperature of the compressor, the higher the exergy rate destruction.
