    [SINGAPORE] Data centre provider ST Telemedia Global Data Centres (STT GDC) on Wednesday (Jun 10) said it is expanding its Jakarta data centre campus to meet the country’s rising cloud, AI and digital infrastructure needs.

    The group said that under the move, the STT Jakarta 2 data centre would be launched, and the STT Jakarta 3 centre would be completed; on top of these, construction of STT Jakarta 5 and STT Jakarta 6 would be started.

    In a statement, the Singapore-headquartered firm said that STT Jakarta 2 commences operations with 24 megawatts (MW) of IT load capacity; STT Jakarta 5 and STT Jakarta 6 will support the campus with 40 MW of IT load each under the next phase of development.

    STT Jakarta 3 is designed to meet benchmarks such as targeted improvements in energy efficiency and the use of lower-global-warming-potential cooling systems, in line with recognised green financing frameworks.

    Long-term development pipeline

    The expansion is meant to advance a long-term development pipeline of more than 360 MW of “AI‑ready, sustainable IT capacity” in Indonesia.

    Saribua Siahaan, a director on Indonesia’s Investment Coordinating Board, said: “The potential for data centre development in Indonesia is highly significant, driven by the rapid pace of digital transformation and the increasing demand for reliable and secure information technology infrastructure.”

    The venture is supported by an on‑site high‑voltage substation to enhance power reliability and shorten the path from generation to IT load, so that the campus can deliver scalable, power-secured infrastructure for hyperscale and enterprise customers.

    The KKR-Singtel-owned company said the substation will improve the overall energy performance of the site by reducing transmission losses and enhancing power quality to the campus.

    Indonesia is one of South-east Asia’s fastest-growing digital markets, where there is rising cloud adoption, accelerating AI development and growing demand for locally hosted digital infrastructure.

    The country’s digital economy is projected to hit US$130 billion by 2026, with AI positioned as a key engine driving the growth of productivity, innovation and competitiveness. Its data centre capacity is also projected to reach about 2.7 gigawatts by 2030.
