Jakarta, INTI - PT Pertamina Geothermal Energy Tbk (PGEO) has announced plans for a potential groundbreaking of a Green Data Center powered by geothermal energy.
At the end of December 2025, PGEO revealed its strategy to optimize geothermal energy beyond the electricity sector, targeting strategic industries such as green data centers.
For this development, PGEO has collaborated with the Indonesia Data Center Provider Organization (IDPRO) and the Faculty of Engineering at the University of Indonesia (UI) to conduct preliminary studies and planning.
PGEO President Director, Ahmad Yani, emphasized that geothermal energy, as a stable baseload power source, has strong potential to supply domestic data centers.
“Because geothermal is baseload energy, it can run 24 hours. We can support the electricity needs,” he said during a visit to Kontan’s office on Wednesday, February 18, 2026.
Partnerships, Market Potential, and Sustainability Impact
He also mentioned that PGEO is currently looking at potential partners, notably the U.S.-based company Microsoft, whose data center projects are already active in Indonesia. Microsoft has launched its Indonesia Central Cloud Region, including the JKT09 project in Karawang, as part of a US$1.7 billion (IDR 27 trillion) investment through 2028 to support AI and cloud ecosystems.
“We have been exploring all parties, including IDPRO and potential partners like Microsoft. Recently, we were introduced at the Ministry of Investment to discuss potential collaboration with Microsoft. Hopefully, this can be one of the entry points,” Ahmad Yani explained.
He further confirmed the potential for a groundbreaking ceremony for the Green Data Center project.
“We are moving in that direction. The groundwork has been explored,” he added.
Using geothermal energy in data centers also offers significant environmental benefits, with very low or near-zero carbon emissions compared to conventional fossil-fuel-powered data centers. This supports companies in achieving net-zero goals and reducing their environmental footprint.
“We invite everyone to join us, but we also need to prove it with pilot projects, like the ongoing work in Kamojang. We aim to integrate both external and internal partners,” he said.
Ahmad Yani noted that Indonesia’s data center demand is entering a phase of digital transformation, driving rapid growth. According to the Ministry of Communication and Digital Affairs, this trend is supported by over 212 million internet users, with the number of data center facilities expected to rise through 2029–2030.
Projected industrial electricity consumption indicates that approximately 26% of increased energy demand will be driven by data center growth. Accordingly, national data center capacity is expected to jump from 520 megawatts (MW) in 2025 to 1.8 gigawatts (GW) by 2030.
“This opens opportunities for PGEO to further engage in the low-carbon digital sector,” he concluded.
Conclusion
PGEO’s initiative to develop a geothermal-powered Green Data Center positions the company at the forefront of Indonesia’s low-carbon digital infrastructure. Through strategic partnerships, sustainable energy solutions, and alignment with national data center growth, PGEO is set to support both environmental goals and the country’s digital transformation.
