GEO Records an Increase in Installed Capacity of 727 MW in 2025

PT Pertamina Geothermal Energy Tbk (PGEO) recorded an increase in installed capacity of power plants by 727 MW throughout 2025. This figure has increased compared to 2024 which was recorded at 672 MW.

Director of Exploration and Development of PT Pertamina Geothermal Energy Tbk., Edwil Suzandi, explained that this capacity increase was supported by the Lumut Balai Unit 2 PLTP with a capacity of 55 megawatts (MW) which officially operated at the end of June 2025.

"The achievement throughout 2025 is an important foundation for PGE to accelerate geothermal development. We are committed to expanding capacity, strengthening collaboration, and creating more value for Indonesia on the journey to energy transition," said Edwil, Saturday, January 17.

Beyond this capacity achievement, PGE also expands its contribution to the national energy self-sufficiency agenda through strengthening synergies and developing strategic projects.

In August, PGE signed a Heads of Agreement (HoA) with PLN Indonesia Power which was facilitated by Danantara Indonesia for the development of 19 geothermal projects with a total capacity of 530 MW.

In line with this, four PGE projects were also selected to be included in the Bappenas Blue Book 2025-2029, which opens up opportunities for international financing support of up to 613 million US dollars.

"To expand the benefits of geothermal energy beyond the electricity sector, PGE launched a Green Hydrogen Pilot Project in Ulubelu, Tanggamus Regency, Lampung Province, last August," he said.

This initiative, continued Edwil, is PGE's first step in building an integrated green hydrogen ecosystem, from production, distribution, to utilization, as part of efforts to support the transition to a low-carbon industry.

In addition to the development of green hydrogen, PGE has also started to pioneer the development of green data centers based on geothermal energy. This step is marked by the signing of a Memorandum of Understanding and Framework Agreement with the Indonesia Data Center Provider Organization (IDPRO) and the Faculty of Engineering, University of Indonesia. This collaboration is the foundation for the development of more sustainable geothermal energy-based digital infrastructure.

Edwil also said that PGE is currently working on various strategic projects with a target commercial operation date (COD) phased until 2029, which includes the Hululais PLTP Units 1 and 2, the Lumut Balai PLTP Unit 3, the Lahendong PLTP Unit 7, Unit 8, and Bottoming Unit 2, and the exploration of the Gunung Tiga PLTP.

"All of these project portfolios support the target of 1 GW capacity in 2-3 years and 1.8 GW in 2033, while strengthening PGE's role in supporting national energy self-sufficiency and the Net Zero Emission 2060 target," he said.
