The Government of Indonesia is committed to realize a policy of 35,000 Megawatt (MW) of an additional supply of electricity within 5 years (2014-2019). The projection of this capacity is largely supported by fossil fuel power plants and a small portion of renewable energy. One of the renewable energy which currently has great potential in Indonesia is the geothermal. Therefore, improving the capacity of geothermal is needed to support the policy. The Kamojang is one of the largest geothermal power plant in Indonesia with an installed capacity of 235 MW from 5 generating units. The purposes of this research is to calculate the energy and exergy analysis at Kamojang geothermal power plant. To improve the capacity, exergy analysis can be used by employing the thermodynamic method. In this research, unit 2 of Kamojang's plant is employed. The analysis was examined by using the Engineering Equation Solver (EES) code. The results show the first law of efficiency was calculated at 19.03% and the second law of efficiency at 40.31%.
