NTT DATA Expands Jakarta Data Center Capacity to 12 MW as AI Boom Drives Regional Spillover from Singapore

JAKARTA, Investortrust.id — NTT DATA officially inaugurated the Jakarta 2 Annex Data Center (JKT2A) on Tuesday, adding 12 megawatts of dedicated IT load to bolster enterprise computing capacity amid soaring regional demand for artificial intelligence workloads and cloud services.

The launch underscores a broader structural shift across Southeast Asia's digital economy, as severe land shortages and power grid caps in Singapore push international tech giants to build out regional secondary hubs. With domestic data center capacity in Greater Jakarta already running near full utilization and artificial intelligence workloads demanding unprecedented energy and processing density, Indonesia is rapidly emerging alongside Malaysia and Thailand as a primary beneficiary of hyperscale infrastructure spillover.

Photonics Integration Across Metro Hubs

The new facility is situated within the NTT Global Data Centers campus in central Jakarta and integrates directly with the existing Jakarta 2 (JKT2) facility. The site functions as a major connectivity hub, hosting more than 240 network carriers, the Jakarta Internet Exchange (JKT-IX), global cloud access ramps, and subsea cable landing terminations.

To improve resiliency across its footprint, NTT DATA debuted APN Connect in Indonesia, a proprietary low-latency network underpinned by the Innovative Optical and Wireless Network (IOWN) All-Photonics framework. The link provides high-throughput optical transmission directly between the JKT2 and JKT2A campus and the group's JKT3 facility situated roughly 35 kilometers away.

According to Katsuhiko Kawazoe, President and Chairperson of the IOWN Global Forum and Chief Executive Fellow at NTT, Inc., contemporary data center resilience requires moving beyond isolated campuses. He noted that modern facilities must be seamlessly interconnected into unified operational fabrics, ensuring multi-site redundancy and real-time replication to support business continuity and mission-critical cloud applications.

The Tier III-certified JKT2A complex features dual-feed substation architecture, 2N uninterrupted power supply (UPS) systems, and N+1 standby diesel generators. Cooling systems run on concurrent N+1 and N+2 maintenance pathways paired with carrier-neutral telecommunication access.

Regional Spillover Beyond Singapore

The Jakarta launch highlights Indonesia's growing appeal as hyperscalers navigate resource bottlenecks across Southeast Asia. Addressing reporters during the opening ceremony, Yasuhiro Kajiki, Managing Director for Japan and APAC at NTT Global Data Centers, observed that persistent land constraints and electricity supply ceilings in Singapore have made alternative destinations increasingly compelling.

Kajiki explained that Indonesia’s vast domestic base of digital consumers and mobile devices makes it a top-tier regional investment priority for NTT, even as neighboring markets such as Malaysia and Thailand also compete aggressively to attract AI infrastructure. While the group declined to disclose the capital expenditure earmarked for this specific expansion, NTT has established deep operating roots in Indonesia over 52 years, deploying over $500 million in cumulative capital and maintaining a local workforce of more than 2,000 employees.

He emphasized that growing AI requirements are shortening development lead times and accelerating customer requests for denser power capacities. For now, the Japanese company remains concentrated on the Greater Jakarta metro area due to concentrated enterprise demand, while actively assessing long-term satellite expansions into strategic border corridors like Batam.

Domestic Capacity Nears Full Utilization

The addition of JKT2A comes as existing Indonesian infrastructure faces tightening availability. PT Telkom Data Ekosistem (NeutraDC), the data center subsidiary of state-controlled telecommunications operator PT Telkom Indonesia (TLKM), confirmed that its 21.5-megawatt Hyperscale Data Center (HDC) in Cikarang reached full capacity utilization in the fourth quarter of 2026.

With Building 1 completely committed across all enterprise tenants, NeutraDC is mapping a phased roadmap to scale its footprint to 400 megawatts, with a longer-term ambition of capturing 1 gigawatt across domestic and regional hubs.

"The full occupancy of Building 1 in Cikarang reflects expanding market demand for digital infrastructure," said Rakhmad Tunggal Afifuddin, Chief Executive Officer of NeutraDC Group. "For NeutraDC, this is not merely about adding capacity, but ensuring that the infrastructure we build remains relevant to customer needs and future technological advances."

To execute the expansion, NeutraDC is reviewing industrial land parcels recommended by national investment body Danantara Indonesia, prioritizing reliable power supply, network interconnectivity, and sustainability. The operator is aligning future builds around three core pillars: colocation, AI-driven compute capacity, and multi-cloud interconnectivity.
