| Abstract | Indonesia is committed to complying with the Paris Agreement on Climate Change and has outlined its energy transition strategies through the LTS-LCCR 2050. One of the renewable energies that can replace fossil fuel plants is geothermal energy. Although promising, geothermal energy is known for its high investment cost and risk, so careful prioritisation and decision-making are required. This paper aims to develop a comprehensive decision-making framework to give insights to decision-makers and stakeholders. This paper's proposed framework uses a combination of techno-economic multi-criteria decision analysis. GEOPHIRES v2.0 is used for techno-economic analysis. Analytical Hierarchy Process (AHP) is suggested for the multi-criteria decision analysis to evaluate the geothermal fields using various sustainable development criteria. Three scenarios of the LTS-LCCR 2050 (CPOS, TRNS, and LCCP) are used as the basis for weighting to determine the field prioritisation, which is reflected through the final AHP scoring. The above framework is applied to ten different geothermal greenfield projects across Indonesia. The results are ranked and compared using the above developed framework. Comparison with other rankings (e.g. RUPTL 2021-2030) leads to insights into the decision-making process and method. This work suggests that fields located on Sumatra Island and Java Island should be prioritised more highly in the context of energy transition. A more comprehensive result can be achieved by including new variables in the indicator level of the AHP structure. |
