A combined cycle power plant (CCPP) plays an important role in supplying electrical energy in Indonesia. It is important to do an energy audit to this industry. This audit's purposes are as an effort to find a way to conserve the energy and as an inspection to the industry for PROPER’s (Program Penilaian Peringkat Kinerja Perusahaan) purpose. This study is focused on Third Plant CCPP in Tanjung Priok with 743 MW capacity. <br /> <br /> The energy assessment targets the CCPP with its all possible working load, low, middle and high working load. Methods used are data gathering from the control room, calculating parameters using thermodynamics principles, and data analysis. <br /> <br /> The data shows that the two plants are mainly operated in high working load. The analysis results shows that CCPP efficiency will rise up to above 50% if it works on middle and high working load, and efficiency will be around 44% if it works on low working load. Based on this study, suggestion has given to use 1-1-1 formation if using CCPP for low working load so that the efficiency will be risen. <br />
