Jakarta, CNBC Indonesia – Indonesia has a ‘treasure’ in the new renewable energy (EBT) sector in the form of geothermal (geothermal). Geothermal potential is the second largest in the world after the United States.
Director of Geothermal at the Directorate General of New, Renewable Energy and Energy Conservation (EBTKE) of the Ministry of Energy and Mineral Resources (ESDM) Harris said Indonesia has a potential of 23,700 megawatts (MW) currently identified.
“We currently have 23,700 MW identified, some have even identified more with advanced technology,” he explained in a seminar, Thursday (23/09/2021).
Harris said that by 2035, a Geothermal Power Plant (PLTP) of 9,300 MW will be built. According to him, the projected addition of this capacity has been scheduled in the Business Plan for the Provision of Electricity (RUPTL) 2021-2030.
“The draft already has numbers and in the short term until 2025 it reaches the 23% EBT target, there is a target to build a geothermal power plant with a capacity of 3,575 MW. Currently, the installed capacity of 2,175 MW has an additional 1,400 mega,” he explained.
He further said that in the RUPTL until 2030 there is an additional capacity from geothermal of 2,620 MW. According to him, the additional capacity from the PLTP will be spread across Java, Sulawesi, Maluku, and Nusa Tenggara.
In order to encourage the acceleration of geothermal utilization, the government also has a program called government drilling. Where the government conducts exploration drilling funded and carried out by the government.
“Government drilling is an exploration program funded and carried out by the government to reduce the risk of geothermal projects,” he explained.
Harris explained that one of the reasons for the high price of electricity from geothermal is the high exploration risk. According to him, the risk of successful exploration to achieve the expected target is less than 50%.
“One well is US$ 5-7-8 million per well if it fails, it will be the cost of the total project,” he continued
