Jakarta is offering investors abundant land and assured electricity, but grid capacity, clean-energy access and digital connectivity will determine whether the offer is commercially credible.
Indonesia has invited global investors to build data centres across its archipelago, promising that state electricity utility PLN will provide the capacity they require as Jakarta pursues a larger share of Southeast Asia’s cloud and artificial-intelligence infrastructure market.
Energy and Mineral Resources Minister Bahlil Lahadalia made the pitch at Electricity Connect 2026 in Tangerang, near Jakarta. Indonesia’s size, its thousands of islands and its mix of solar, hydroelectric, geothermal and wind resources, he argued, give developers room to expand. The government would facilitate investment, while PLN would prepare the necessary power supply.
The commercial opportunity is substantial. Indonesia’s data-centre market was valued at an estimated $1.44 billion in 2025 and is forecast to reach $3.48 billion by 2031, representing annual growth of almost 14%, according to figures cited by the Investment Ministry. Demand is being driven by cloud migration, e-commerce, digital payments, AI workloads and data-localisation requirements.
Yet available land is not the decisive factor.
Data centres require uninterrupted power, redundant fibre connections, reliable cooling systems and sites protected against flooding, earthquakes and other physical risks. Large AI facilities can consume as much electricity as industrial complexes. For international operators facing pressure to reduce emissions, the source of that power matters almost as much as its availability.
Indonesia had roughly 370 megawatts of data-centre capacity in 2025, according to the Communications and Digital Ministry, which projects demand could reach 1,410 MW by 2029. Closing that gap will require concentrated development zones, faster permitting and dedicated electricity infrastructure—not simply offers of undeveloped islands.
Batam shows what a viable cluster can look like. The island lies close to Singapore, connects to regional submarine-cable networks and has been developed as a special economic and digital-investment hub. DBS and UOB recently provided Rp6.7 trillion, or about $411 million, to finance three facilities with a combined capacity of approximately 72 MW at Batam’s Nongsa Digital Park.
Replicating that model elsewhere will be harder. Renewable resources in Papua or Kalimantan may be large, but generation potential does not automatically translate into firm electricity at a data-centre site. Transmission lines, substations, fibre routes and backup systems must be financed and completed first.
PLN’s investment burden is already heavy. Indonesia’s 2025–2034 electricity plan calls for 71 GW of additional generation and about 48,000 circuit-kilometres of new transmission, with private companies expected to develop 60% of the new plants. Coal still supplies more than half of installed capacity, while renewables account for roughly 15%.
That mismatch creates both opportunity and risk. Renewable developers, construction groups, cable operators and cooling-technology suppliers could benefit from new data-centre corridors. PLN, however, should avoid building expensive connections against speculative demand. Binding capacity agreements, phased connections and developer contributions would reduce that exposure.
Indonesia can become a stronger regional data-centre base. But investors will judge specific sites, power contracts and connection schedules—not the number of islands available.
