BDx Data Centers has started construction of a 640MW AI data center campus in Jatiluhur, West Java, as demand for high-density computing accelerates across Southeast Asia. The CGK4 campus will combine 845MVA of secured grid capacity, direct-to-chip liquid cooling and support for racks of up to 500kW, with its first 120MW building targeted for service in early 2027.
BDx Data Centers is expanding its AI infrastructure footprint in Indonesia with the groundbreaking of AI Campus 2, also known as CGK4, a planned 640MW data center campus in Jatiluhur, West Java.
The project is designed around a problem increasingly shaping the data center industry: securing enough power and cooling capacity to deploy increasingly dense AI computing systems.
CGK4 has secured 845MVA of grid capacity from Indonesia’s state utility PLN. BDx says that capacity forms part of more than 1.2GVA of secured power across its AI-ready campuses in Indonesia, which also include CGK3/3A and CGK5.
The six-building CGK4 campus is expected to be developed over approximately three years, with construction and commissioning taking place in phases. Work has already started on Building 1, which is planned to deliver 120MW of IT capacity. Its first contracted phase is expected to enter service in early 2027.
The scale of the development reflects how AI is changing the physical requirements of data centers. Traditional enterprise workloads can operate at comparatively modest rack densities, while AI training and inference clusters built around GPUs and other accelerators generate substantially greater electrical and thermal loads.
CGK4 is being designed with direct-to-chip liquid cooling capable of supporting up to 500kW per rack. That puts thermal management alongside electricity procurement as a central part of the campus architecture.
NVIDIA’s DGX-Ready Colocation Data Center program, under which CGK4 achieved certification in April 2025, is intended for facilities capable of supporting NVIDIA accelerated computing infrastructure. NVIDIA’s partner directory describes the program as covering both air-cooled and advanced liquid-cooled data centers designed for high-density computing.
BDx’s earlier development at the Jatiluhur site had been positioned as an AI-focused facility capable of supporting high-density workloads. The company has now increased the planned CGK4 capacity to 640MW as demand for larger AI deployments has developed. BDx’s current facility information lists the site at 640MW of IT capacity and 845MVA of PLN utility supply.
Power availability is becoming a defining constraint for AI infrastructure developers across Asia-Pacific. CBRE’s 2026 regional data center outlook says data center electricity consumption in the region nearly doubled between 2020 and 2024 and is expected to triple over the next few years. The firm also says average new data center projects are now exceeding 100MW as AI workloads increase power requirements.
JLL expects Asia-Pacific to add 4.8GW of data center supply by 2027, with 78% of that upcoming capacity already preleased. The research firm also points to increasing grid-connection delays as a constraint on new development.
That environment makes BDx’s secured power position a significant part of its Indonesia strategy. Rather than treating power procurement as a later-stage infrastructure issue, the company is building its AI campus expansion around utility capacity that has already been secured.
The Jatiluhur location also provides an opportunity to develop lower-carbon power options. CGK4 will receive electricity through PLN’s national grid, while BDx says it is pursuing additional lower-carbon pathways, including a proposed hydroelectric arrangement with Perum Jasa Tirta II. The site is approximately five kilometers from the Jatiluhur Dam.
The sustainability strategy is relevant because AI data centers are increasing pressure on both electricity systems and cooling infrastructure. Liquid cooling can enable higher-density computing, but operators must simultaneously manage water, electricity, equipment and environmental requirements as campuses scale.
Indonesia is attracting increasing attention from data center developers as demand grows for cloud services, AI computing and digital infrastructure. CBRE reported in August that data center operators accounted for more than 100 hectares of industrial land transactions in Indonesia during the first half of 2026, illustrating the scale of competition for sites with suitable infrastructure.
BDx is also positioning CGK4 around data sovereignty and regional AI deployment. The company says the campus is attracting interest from hyperscalers, global technology companies, AI-native cloud providers and enterprises looking for AI-ready capacity in Southeast Asia.
The strategy is consistent with a wider shift toward large AI campuses rather than conventional data center halls. JLL’s 2026 global outlook projects the worldwide data center sector to expand at a 14% compound annual growth rate through 2030, with AI potentially accounting for half of data center workloads by the end of the decade.
For Indonesia, the combination of available land, grid access and growing domestic demand is becoming strategically important. BDx has secured a US$320 million loan facility in 2026 to support its expansion, according to the company and regional reporting.
CGK4 therefore represents more than an additional colocation facility. Its 640MW design, high-density liquid cooling and phased deployment model show how data center operators are adapting physical infrastructure around AI accelerator workloads.
The immediate milestone will be Building 1. If its first contracted phase enters service as planned in early 2027, it will provide BDx with a 120MW initial platform from which to expand the broader six-building campus as demand develops.
Market Landscape
AI is pushing Asia-Pacific data center development toward larger campuses, higher rack densities and earlier power procurement. CBRE says global hyperscale demand is growing at a 14% CAGR, while technology companies plan to increase AI capital expenditure by 61% in 2026. The firm also identifies power availability as a major constraint on regional data center expansion.
Indonesia is emerging as one of Southeast Asia’s important development markets. JLL reported in August that roughly 80% of industrial-land demand within its research coverage was coming from data center operators, while requirements for individual sites have grown toward 10–30 hectares.
The competitive landscape includes hyperscalers, colocation providers, neocloud companies and specialist AI infrastructure developers. As GPU clusters become denser, access to power, high-capacity connectivity and advanced liquid cooling increasingly influences where these facilities can be built and how quickly they can become operational.
