PGE studies direct geothermal power supply for data centres
A planned 5 MW pilot at Kamojang in West Java has completed its technology study, while commercial and regulatory assessments remain under way.
PT Pertamina Geothermal Energy Tbk. (PGEO) is assessing commercial and regulatory requirements for a planned data centre powered directly by geothermal electricity at Kamojang in West Java, president director Ahmad Yani said.
Speaking at a media briefing in Jakarta on 4 November 2026, Yani said the technology study was complete. The company plans to begin with a 5 megawatt (MW) pilot to demonstrate that a data centre can run entirely on geothermal power, without connections to other electricity sources.
The proposed arrangement would differ from the usual model of data centres connected to PLN’s electricity network. PGE hopes the pilot can serve as a reference for similar developments in its other operating areas.
Exploration director Edwil Suzandi said preparations include revising the environmental impact assessment, known as AMDAL. The planned supply of electricity to data centres requires environmental approval different from that covering PGE’s existing operations, he said.
PGE is also examining whether supplying a data centre directly would affect the electricity it currently delivers to PLN. The company hopes to complete the assessments by the end of 2026 or in the first quarter of 2027, allowing it to move to the next development stage.
Edwil said securing a prospective buyer, or offtaker, was a key requirement. PGE is holding intensive discussions with several data centre industry players about potentially buying geothermal electricity, with development dependent on meeting commercial and regulatory requirements.
