Digital Realty has partnered BW Digital to strengthen cross-border data centre connectivity between Singapore and Indonesia, anchoring the new Nongsa Changi Cable System (NCC) at Digital Realty’s SIN12 facility. The collaboration aims to support rising regional demand for cloud, AI and high-performance computing workloads.

The agreement will see both companies jointly support the rollout of NCC, a new submarine cable linking Batam and Singapore. NCC will be integrated directly into SIN12, one of Digital Realty’s flagship data centres in Singapore, enabling faster and more resilient DC-to-DC connectivity for enterprises expanding across Southeast Asia.

Subsea system to boost Singapore–Batam AI capacity

The NCC will be the first submarine cable to land in Nongsa Digital Park, a rapidly developing hub for hyperscale and AI infrastructure. The system is designed to deliver more than 1.6 petabits per second (Pb/s) of capacity and achieve sub-2 millisecond latency to Singapore.

By landing NCC directly into Digital Realty SIN12, the companies aim to support increased AI, cloud and interconnection demand while improving the resilience of regional digital infrastructure. SIN12’s ability to host high-performance workloads at scale is expected to give enterprises a smoother pathway to expand across Singapore, Batam and the broader SIJORI (Singapore-Johor-Riau) growth triangle.

The partnership also integrates subsea cable landing capabilities with Digital Realty’s global PlatformDIGITAL®, enabling customers to run AI/ML computing environments close to submarine routes and major cloud nodes.

“Subsea networks are central to Southeast Asia’s digital economy, and Singapore continues to serve as a critical gateway for regional data exchange. By integrating BW Digital’s Nongsa–Changi system into SIN12, we are working to deliver faster and more resilient connectivity to support customers as they scale next-generation workloads,” said Serene Nah, Managing Director and Head of Asia Pacific at Digital Realty.

Expanded interconnection options for enterprises

Customers of BW Digital may also gain the ability to establish direct interconnections within SIN12, with seamless cross-connects to other cloud, carrier and service providers already hosted in the facility. The arrangement is expected to allow enterprises to scale AI workloads more efficiently while lowering cross-border connectivity costs.

Beyond subsea integration, BW Digital’s upcoming NDP-1 data centre in Batam is positioned as a high-density “AI factory” with 144MW capacity and liquid cooling capabilities. NDP-1 is being designed with direct on-ramps to the subsea landing station, enabling low-latency links from Batam to Singapore and onward to regional markets.

“This partnership represents a major milestone for BW Digital, aligning with our mission to support digital transformation by bridging the gap between submarine cable infrastructure and land-based digital platforms in a way that is efficient, secure, and future-ready,” said Virgine Frouin, Chief Business Officer of BW Digital.

She added that the collaboration aims to strengthen reliable, secure connectivity between Singapore and Batam and support rising demand for cross-border data exchange, particularly for AI-driven workloads.

NCC and NDP-1 are both under development, with further integration milestones to be announced as construction progresses. Digital Realty and BW Digital’s partnership will continue to evolve as regional requirements for AI, cloud and interconnection accelerate.
