Biznet launches Bali AI data center, plans BNCS-2 cable

The new Biznet AI Center in Arya Nagari, Bali is designed for heavy AI workloads, with up to 145 kW per rack, direct liquid cooling and chilled-water closed-loop systems. It also includes an AI development lab and solar-powered energy support, putting sustainability and power efficiency at the center of the buildout as data centers face tighter scrutiny over electricity and resource use.

The subsea expansion is equally important. After BNCS-1 linked Java and Sumatra in 2024, Biznet now plans BNCS-2 to connect Surabaya, Banjarmasin, Sumenep and Buleleng. That would extend high-capacity fiber across more of the archipelago, where uneven backbone infrastructure often leaves smaller cities and islands with slower or less stable service.

For investors, the story is not about Biznet as a public-market name — it is a read-through for the broader digital infrastructure trade. Demand for AI-ready facilities, fiber routes and undersea capacity is rising across Asia, while power constraints, land shortages and tougher regulations remain the main execution risks, as data center peers have warned in recent filings.

The development also highlights the growing overlap between data centers and subsea networks. Companies with both compute and transport infrastructure can capture more traffic, improve service quality and reduce dependence on third parties, a structural advantage as AI applications become more bandwidth- and latency-sensitive.

Biznet, which started in 2000 as a wireless provider and now reaches more than 200 cities and regencies across Indonesia, said the expansion is aimed at giving customers a better service experience and opening more digital opportunities. The next catalyst will be how quickly BNCS-2 is built out and whether Bali’s AI facility becomes a template for further capacity additions across the region.
