Abstract
Based on RUPTL (Project of Electric Power Provision) PLN 2017-2026, Total power that has been provided in South-Central Borneo Electrical System is 895,6 MW. Given the ratio of households that use PLN electricity in Central Borneo is still low, then the growth of electricity demand in Central Borneo estimated to be high for the next 5 years. To meet the electricity demand until 2026, in South-Central Borneo will be scheduled to be build some power plants, some of it is gas power plants. There are 7 gas power plants that will be built until 2025. To increase the reliability of this development plan and fulfilled the electricity demand in South-Central Borneo, this research will be about the conceptual design of mini LNG supply chain for Power Plants in South-Central Borneo. In this research, to design the concept mini LNG supply chain will be by selecting the most suitable location for the receiving terminal in South Borneo with 3 alternatives of location such as Tamban, Kuin Kecil, and Offshore and the most suitable regasification technology with 4 alternatives of vaporizer such as Open Rack Vaporizer, Submerged Combustion Vaporizer, Ambient Air Vaporizer, and Intermediate Fluid Vaporizer. The selection process is using Elimination and Choice Expressing Reality (ELECTRE) method. And then, the conceptual design will be evaluated on the economy feasibility aspect with 3 parameters: Net Present Value (NPV), Internal Rate of Return (IRR), Payback Period and Sensitivity Analysis. Based on the selection method, the most suitable location for receiving terminal in South Borneo is in Tamban, and the most suitable vaporizer will be Ambient Air Vaporizer. While the receiving terminal in Central Borneo will be in Kumai. The LNG will be transferred from the source, FSRU Makassar, using Self-Propelled LNG Barge 12,000 m3. The selling price LNG is variated by range of margin US$2.75 – US$3.75. Based on the NPV, IRR, and Payback Period, all of the range of margin is feasible in economic aspect. But, when the sensitivity analysis has been done. It is more effective to do the investment gradually based on the Commercial Operation Date (COD) of each power plants start with margin US$3.25 with the payback period of 7 years, IRR 20,46% and NPV US$92,126,692 at the end of 2049. And still has positive NPV value at US$12,323,157, IRR 12.87% with the payback period 11 years after increasing the total CAPEX and OPEX by 30%.
