Indonesia Strengthens Digital Infrastructure with Nongsa-Changi Submarine Cable
The government continues to strengthen the development of national digital infrastructure, supported by reliable connectivity, sustainable energy supply, and transparent business certainty. This effort aligns with President Prabowo Subianto’s directive to accelerate digital transformation.
“Today we celebrate the landing of the Nongsa-Changi Submarine Cable System. This infrastructure forms the physical foundation for a new digital corridor, strengthening one of the fastest and closest digital connections in Southeast Asia between Indonesia and Singapore. The system, developed by Telin together with BW Digital, will deliver additional capacity of more than 1.6 petabits per second with latency of less than 2 milliseconds between our two countries,” said Coordinating Minister for Economic Affairs Airlangga Hartarto in a written statement on Monday (20 July 2026).
This low-latency capacity will support a range of strategic digital services, including advanced cloud computing, artificial intelligence (AI) inference, high-frequency financial transactions, and the development of next-generation digital services.
The Nongsa-Changi cable is not merely connectivity infrastructure, but also the physical foundation for the formation of a new digital corridor in the Southeast Asian region.
Indonesia currently has 235.26 million internet users with a penetration rate of 81.72%, whilst fixed broadband subscribers have reached 99.5 million. Indonesia is also the fourth-largest potential AI market in Asia after China, India, and Japan, with a market value of USD 70 billion, or around 6.4% of the Asian AI market.
Batam is regarded as developing rapidly as Indonesia’s second digital gateway after Jakarta, supported by its strategic location, reliable connectivity, growing energy supply, and a policy environment conducive to investment.
BW Digital’s NDP1 facility at Nongsa Digital Park has an IT capacity of 120 MW, whilst DayOne, together with INA, is developing a new hyperscale campus with contracted electricity supply pathways towards 450 MW. Oracle has even selected Batam as its Indonesia North Cloud Region.
These developments owe much to the Indonesia-Singapore Six Working Group (6WG) cooperation, particularly in the Batam-Bintan-Karimun (BBK) area, which continues to drive strengthened connectivity and digital investment in the region.
The Nongsa-Changi cable is one of the concrete follow-ups to the Leaders’ Retreat between President Prabowo Subianto and the Prime Minister of Singapore in early July 2026.
The government is also continuing to strengthen energy provision and business certainty to support digital infrastructure development. Indonesia is targeting the expansion of renewable and mixed energy capacity to more than 100 GW within this decade.
Separately, Indonesia entered discussions on accession to the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) on 26 June 2026, whilst the accession process to the Organisation for Economic Co-operation and Development (OECD) is proceeding in parallel to build a transparent and predictable business environment.
“Let us build this digital corridor not only with cables and data centres, but also with trust, partnership, and a shared vision. May its benefits be felt not only by Indonesia and Singapore, but by the entire ASEAN region and the world,” Airlangga Hartarto concluded.
