Jakarta. Indonesia’s data center industry is attracting fresh capital as global operators race to expand infrastructure to meet rising demand for cloud computing and artificial intelligence workloads.

Singapore-based ST Telemedia Global Data Centres (STT GDC) has expanded its Indonesia financing platform to Rp 8.8 trillion ($500 million), including its first green loan facility in the country, to support the continued development of its STT Jakarta Campus in Cikarang, Bekasi.

The dual-currency financing facility, comprising US dollar and rupiah components, will fund the expansion of STT Jakarta 1-3 and provide additional capacity for future growth. The financing was arranged by OCBC NISP, HSBC Indonesia, and Bank Negara Indonesia (BNI), with OCBC also acting as Facility Agent and Sole Green Coordinator.

“This transaction marks the next step in our Indonesia financing platform, enabling us to support the continued expansion of the STT Jakarta Campus while introducing our first green loan tranche in the country,” STT GDC Indonesia Country Head Hendrikus Gozali said in a statement on Wednesday.

The green loan tranche will be used to develop STT Jakarta 3, a facility designed to support both liquid-cooling and advanced air-cooling architectures for next-generation, high-density computing workloads.

Upon full completion, the STT Jakarta Campus is expected to support more than 360 megawatts (MW) of IT capacity.

Gozali said STT Jakarta 3 is being developed in line with sustainability targets, including a Power Usage Effectiveness (PUE) ratio of 1.30, LEED Gold certification, and cooling systems using ultra-low Global Warming Potential (GWP) refrigerants.

“The facility also includes features that provide capacity for future expansion, allowing STT GDC to grow alongside customer demand without requiring structural renegotiations,” he said.

The latest investment comes as Indonesia's data center market continues to expand rapidly.

Earlier, Asian data center operator Princeton Digital Group (PDG) announced the acquisition of a new site in Greater Jakarta for its latest hyperscale data center campus, JC4. The project will deliver 240 MW of capacity across four data center buildings, each capable of supporting 60 MW.

Spanning 106,217 square meters, the campus is designed to support high-density computing and advanced cooling systems tailored for cloud and AI applications.

“Indonesia remains a key market for digital infrastructure in the region, and JC4 strengthens our existing portfolio by delivering reliable and scalable capacity to support cloud and AI workloads,” PDG Chairman, CEO, and Co-Founder Rangu Salgame said in a recent statement.

According to Cushman & Wakefield’s APAC Data Centre Report H2 2025, Indonesia's total number of data centers increased from 52 to 58 between 2024 and 2025, while the number of operators rose from 28 to 31.

Operational capacity expanded from 278 MW to 321 MW during the period, supported by newly commissioned facilities. Another 186 MW is currently under construction, while projects totaling 901 MW remain in the planning stage.

Cushman & Wakefield Head of Data Centre Group for Asia Pacific Andrew Green said Greater Jakarta continues to strengthen its position as one of the region’s fastest-growing data center markets, with operational capacity projected to increase 4.4-fold by 2030.

“More than one gigawatt of capacity is currently in the development pipeline through 2030, reflecting sustained demand from hyperscalers and enterprises,” Green said.

“Greater Jakarta is also one of the few markets attracting investment from both US and Chinese hyperscalers, further reinforcing its position as a leading data center hub in Southeast Asia.”

Green added that AI and cloud workloads are now the primary drivers of new supply across Asia-Pacific, including Indonesia, pushing developers toward locations with strong power availability and high-capacity infrastructure.

“Governments across the region continue to align policy frameworks with digital infrastructure development, while power availability, sustainability commitments, and regulatory considerations remain key factors in site selection,” he said.
