ABSTRACT
Java-Madura-Bali (JAMALI) system is the biggest electrical system in Indonesia. The system covers more than 50% of total electricity demand in Indonesia. In this area, geothermal and hydro potential is very feasible to be optimized for capacity expansion of power plant in JAMALI system. This paper analyzes optimized plan in developing geothermal and hydro potential in JAMALI system. The analysis was based on the LEAP model. The developed LEAP model was consists of two scenarios. The first scenario is a reference scenario that is used to simulate the capacity expansion with the current status of geothermal and hydro power plant. In this scenario, there were no capacity additions of geothermal and hydro power plant in JAMALI system. The second one is an alternative scenario that is used to simulate the capacity expansion based on the optimized addition of geothermal and hydro power plant. The capacity expansion was based on the projection of electricity demand. The demand was projected based on population and GRDP data. The result shows geothermal and hydro potential can be used to reduce the role of coal fire power plant in JAMALI system. Based on alternative scenario, 21.69 GW of the capacity of coal fired power plant will be replaced by geothermal and hydro power plant in 2025. In the view of environmental aspect, the reduction of the role of coal fired power plant in JAMALI system will reduce the GHGs emission. The average growth rate of GHGs emission is 5.34% per year and 2.69% per year respectively for reference and alternative scenario.
