Jakarta, January 12, 2026 – PT Pertamina Geothermal Energy Tbk (PGE) (IDX: PGEO) marks 2025 as a crucial year for strengthening the foundation of national geothermal development. Throughout 2025, PGE consistently optimized geothermal potential through reliable operational management, increased installed capacity, and strengthened synergy across stakeholders.
These strategic steps are being implemented in line with government policy in the PLN 2025-2034 Electricity Supply Business Plan (RUPTL), which targets a 76 percent share of New and Renewable Energy (NRE) generation, with a geothermal contribution of 5.2 gigawatts (GW). Within this framework, geothermal energy plays a strategic role as a reliable and sustainable clean energy source.
2025 marks a strengthening phase for PGE, emphasizing its role as a driver of national geothermal development. Ahmad Yani, Director of Operations at PT Pertamina Geothermal Energy Tbk, stated, "PGE strives to provide inclusive and innovative clean energy solutions while strengthening the role of geothermal energy as the backbone of the national energy transition and self-sufficiency. The various achievements achieved throughout this year reflect the Company's consistency in maintaining operational reliability, increasing installed capacity, and ensuring that every development step is aligned with the principles of sustainability and good corporate governance."
Ahmad Yani, Director of Operations at PT Pertamina Geothermal Energy Tbk, stated, "This step aligns with the national energy mix transformation agenda outlined in PLN's 2025-2034 RUPTL (Renewable Energy Plan), which targets a 76 percent share of New and Renewable Energy (NRE) generation, with geothermal contributing 5.2 gigawatts (GW). Through various initiatives, PGE strives to provide inclusive and innovative clean energy solutions while strengthening the role of geothermal energy as a pillar of national energy self-sufficiency."
The start of operation of the Lumut Balai Unit 2 Geothermal Power Plant (PLTP) is one step in strengthening the independently managed installed capacity. This achievement increases PGE's total capacity to 727 megawatts (MW), from the previous 672 MW.
In terms of medium- to long-term development, PGE is also continuing its efforts to develop geothermal reserves by commencing greenfield exploration of the Gunung Tiga Geothermal Power Plant in Lampung, with a potential capacity of 55 MW. This project aims to confirm geothermal reserves as a locally based clean energy source and form the foundation for future national geothermal development.
PGE's commitment to supporting the national development agenda is also reflected in the inclusion of several geothermal projects in the 2025-2029 Blue Book of the Ministry of National Development Planning/Bappenas. The inclusion of these projects underscores the strategic role of geothermal energy in supporting sustainable energy investment and strengthens PGE's contribution to achieving long-term national energy targets.
Synergy as a Driver for Strengthening the National Clean Energy Transition
Amidst the complexities of clean energy development, PGE believes that synergy is key to accelerating the national energy transition. This collaborative spirit is realized through a partnership between PT Pertamina (Persero) and PT PLN (Persero). PGE, as a Pertamina affiliate, collaborates with PT PLN Indonesia Power (PLN IP) in developing geothermal power plants.
This synergy reflects a shared commitment to strengthening the national electricity system based on clean energy, while ensuring that geothermal development is carried out efficiently, integratedly, and sustainably. This collaboration between state-owned energy companies is a crucial part of accelerating the national energy transition agenda.
Ahmad Yani added, "Geothermal energy plays a strategic role due to its stable, 24-hour availability. PGE is committed to providing clean, sustainable energy that adds value to the community. Through synergy with stakeholders, we can accelerate geothermal development and strengthen the reliability of the national electricity system."
Presenting Added Value from Geothermal Energy, PGE Consistently Develops Beyond Electricity
More than just an electricity provider, PGE is consistently developing geothermal energy as a value-added energy source. As a world-class green energy company, PGE views geothermal energy not only as a source of electricity but also as having vast potential for development into various advanced uses. As commercial opportunities open up, the development of green hydrogen and green ammonia is projected to grow significantly in the domestic market by 2030 and is part of the Company's strategic direction.
In line with this strategy, PGE is developing Beyond Electricity through the Ulubelu Green Hydrogen Pilot Project and initiating the development of a geothermal-based green data center. These initiatives expand the role of geothermal energy in supporting
