Comparative Assessment of Electricity Supply Strategies in Indonesia 

Abstract

The objective of the study is design an optimal strategies for the national electricity supply in Indonesia for the long term (1996-2021). The situation of the fossil energy reserves is characterized by limited oil reserves, sufficient gas reserves and abundant coal reserves. The GDP grows on average by 6 % per annum. The electricity demand grows by 8.2 % per annum from about 52 TWh in 1991 to 556 TWh in the year 2021. About 70 % is consumed in the industrial sector, which has an average growth rate in electricity consumption of 8.5 % annually. Abundant coal reserves make coal attractive as the major fuel for power plant in Indonesia under the BAU scenario. The ERC scenario carried out in this study showed that clean coal power plants, equipped with desulphurization, denox, and dust filter units, generate electricity at lower costs than LWR nuclear power plants. Coal is by far the most economic supply option even under the conditions of the ERC scenario. For the CRC scenario nuclear power plant would be necessary in 2006 with installed capacity 1.34 GW and grow to 6.72 GW by the year 2021.
