Project InnerSpace, a non-profit organization focused on advancing geothermal energy, has teamed up with Indonesia’s Institute for Essential Services Reform (IESR) to promote geothermal development throughout Indonesia. As the world’s second-largest geothermal power producer, Indonesia holds significant untapped potential, with Project InnerSpace’s GeoMap™ estimating 3,000 GW of geothermal resources. Of this, 20 GW could supply nearly half of Indonesia’s energy demand at a levelized cost of electricity below $150 per MWh.

To unlock this potential, Project InnerSpace and IESR have initiated a collaborative effort to collect insights from key stakeholders. Their work will lead to a comprehensive report, *The Future of Geothermal in Indonesia*, scheduled for release in fall 2025 in English and Bahasa Indonesia. The report will analyze Indonesia’s geothermal opportunities, highlight barriers to investment and policy, and propose practical strategies to expand geothermal development.

The initiative includes contributions from Universitas Gadjah Mada, Enerka, Purnomo Yusgiantoro Center, and Universitas Brawijaya, ensuring a broad range of expertise. Fabby Tumiwa, Executive Director of IESR, stated: “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.”

Jamie Beard, Executive Director of Project InnerSpace, said: “By bringing together Indonesia’s geothermal energy and policy leaders, we can foster collaboration, accelerate the timeline, and turn potential into action.” This partnership aims to drive innovation and investment in Indonesia’s geothermal sector, supporting the country’s sustainable energy goals.

Project InnerSpace has previously published geothermal studies for Texas and Pennsylvania in the United States, with ongoing research in New Mexico, India, and Indonesia. The collaboration with IESR underscores a commitment to harnessing Indonesia’s abundant geothermal resources to meet growing energy needs while promoting environmentally sustainable solutions.

This initiative reflects a shared vision to strengthen Indonesia’s position as a global leader in geothermal energy, fostering economic growth and energy reliability through strategic partnerships and actionable research.
