Ecobiz.asia — PT Pertamina Geothermal Energy Tbk (PGE) (IDX: PGEO) has begun assessing the feasibility of developing Indonesia’s first green data center powered by geothermal energy.
The initiative is part of PGE’s industrialization strategy for geothermal utilization and is being carried out in collaboration with the Indonesia Data Center Provider Organization (IDPRO) and the Faculty of Engineering, Universitas Indonesia (FTUI).
PGE Director of Exploration and Development, Edwil Suzandi, said the study is aimed at meeting the rapid growth of the nation’s digital infrastructure while supporting low-carbon energy development.
“National data center demand is projected to rise from 520 MW in 2025 to 1.8 GW by 2030. This creates a significant opportunity for geothermal to serve as a reliable, low-emission power source for the digital sector,” he said on Friday (Dec. 12, 2025).
According to the Ministry of Communication and Digital Affairs, more than 212 million internet users are driving accelerated expansion of data center facilities, with the sector estimated to consume up to 26 percent of industrial electricity demand.
IDPRO Chairperson Hendra Suryakusuma said geothermal integration could help address long-term energy stability and emissions reduction for the data center industry.
“Data centers must be both reliable and aligned with the national energy transition agenda. This initiative is essential to ensure the digital economy grows sustainably,” he noted.
From the research side, FTUI expressed support for the initiative, viewing it as an opportunity for technological advancement and energy-digital integration.
“Integrating geothermal energy into data center systems opens major innovation potential and strengthens applied research in green technologies,” said FTUI Vice Dean Dalhar Susanto.
PGE states that building a geothermal-powered green data center would improve operational efficiency, reduce carbon footprints, and enhance Indonesia’s competitiveness in the global digital economy.
The effort aligns with PGE’s strategy to accelerate the national energy transition and contribute to Indonesia’s net zero emission target by 2060.
PGE currently manages 15 geothermal working areas with a total installed capacity of 1,932 MW, representing around 70 percent of national geothermal capacity. Its geothermal operations have the potential to reduce emissions by up to 10 million tons of CO₂ annually. ***
