Emission And Financial Analysis Of Geothermal Energy Resource (The Case Of Lahendong Site In Indonesia)

The purpose of this study is to conduct the financial and emission analysis of the Lahendong site as a case study of geothermal powerplant in Indonesia. The outputs of energy model in RETScreen worksheet are power capacity, electricity generation, annual GHG emission reduction, the Internal Rate Return (IRR) and payback period. The sensitivity analyses also were carried out at two scenarios (no grant and with grant) for examining the changes of Feed in Tariff (FiT) and Carbon Credit (CC) impact toward IRR and payback period. Based upon the IRR, payback period and emission CO2 reduction, this study shows the geothermal energy has attractive investment economically and has eco-environmental benefits to be developed. This study is the first analysis about emission and financial analysis using RETScreen software that carried out in Indonesia, therefore this study can be useful for other geothermal resources analysis.
