This paper studies the nuclear power plant development in Java-Madura-Bali area in the Indonesian Long-term electricity planning perspective. Indonesian electricity demand has continuously risen year by year particularly in the Java-Madura-Bali area, or often known as “JaMaLi” area. Holding the largest share for economic activities in the country, it is served by the largest electricity grid in Indonesia called the JaMaLi interconnection system. It is found that the electricity demand in JaMaLi area will increase to 308 TWh in 2025, of which the demand will be dominated by the household sector with 131 TWh or 42% of total electricity consumption. To meet this future demand, a total of 66 GW of installed power plant capacity have to be developed, being fuelled by various energy resources available in Indonesia, excluding nuclear. This paper explores the possibility of long-term electricity expansion planning in the JaMaLi area by including nuclear power plant in order to meet the future demand and environmental protection concern as well as to increase the supply security up to 2027. During the study period, the potential of energy resources available for JaMaLi area along with two electricity supply scenarios based on nuclear and non-nuclear sources are assessed. At the end of the projection, the nuclear power plants may contribute to the reducing of the fossil power plants requirement such as coal and natural gas by 2 GW and 1.9 GW respectively. Meanwhile, the total emission reduction achieved by nuclear scenario is estimated 16.8 million tons of CO2 equivalent.
