Project InnerSpace and IESR have launched an initiative to accelerate geothermal energy development in Indonesia.
Project InnerSpace, an independent non-profit dedicated to overcoming barriers to geothermal energy, has partnered with Indonesia’s Institute for Essential Services Reform (IESR) to expand geothermal development across the country.
Indonesia is already the second-largest geothermal power producer in the world. Yet, according to initial data from Project InnerSpace’s GeoMap™, there’s an estimated 3,000 GW of untapped geothermal potential in Indonesia. Of this, 20 GW could meet nearly half of the country’s energy needs at a levelized cost of electricity (LCOE) below $150 per MWh.
To help harness this potential, Project InnerSpace and IESR have launched an initiative to gather insights and feedback from key stakeholders. Their work will culminate in a report, The Future of Geothermal in Indonesia, set for publication in fall 2025 in both English and Bahasa Indonesia. This report will explore Indonesia’s geothermal prospects, identify investment and policy barriers, and outline actionable strategies for scaling geothermal development.
Contributors to the report include Universitas Gadjah Mada, Enerka, Purnomo Yusgiantoro Center, and Universitas Brawijaya.
“Working in partnership on this initiative with Project InnerSpace, we hope to accelerate development so we can truly take advantage of the vast geothermal resources beneath our feet,” said Fabby Tumiwa, Executive Director of IESR.
Jamie Beard, Executive Director of Project InnerSpace, emphasized that “By bringing together Indonesia’s geothermal energy and policy leaders, we can foster collaboration, accelerate the timeline, and turn potential into action.”
Project InnerSpace’s previous reports have focused on Texas and Pennsylvania in the US, with additional studies underway in New Mexico, India, and Indonesia.
