In Indonesia, the energy transition and digital economy converge around the same need: abundant, reliable and increasingly decarbonized electricity. At the opening of the Indonesia International Sustainability Forum, Investment and Downstreaming Minister Rosan Roeslani presented this convergence as a source of opportunities for capital, particularly in digital infrastructure and industrial value chains.
The challenge is already visible in consumption data. In September 2026, state-owned PLN served 159 data-center customers, representing connected capacity of 2,038 megavolt-amperes and consumption of 2,378 gigawatt-hours. Artificial intelligence and digital services increase the need for continuous supply, while industrial companies seek lower-carbon energy sources to meet market and investor requirements.
New demand requiring network investment
The growth of data centers is not limited to constructing buildings equipped with servers. It requires stable electricity, transmission lines, connection substations and backup capacity. The availability of connected land and telecommunications infrastructure also becomes a location factor. Electricity thus becomes central to the country's digital strategy and competitiveness.
This demand can support new investment, but also risks intensifying grid pressure if capacity expands more slowly than projects. Location choices, facility energy efficiency and coordination with the generation plan will be essential. Clean-electricity supply contracts can provide visibility for businesses while giving renewable producers more predictable markets.
Indonesia is also seeking to connect mineral resources, processing, manufacturing and technology within a more integrated industrial ecosystem. In the first half of 2026, investment in downstream processing activities reached 300.1 trillion rupiah, representing 29.7% of total recorded investment and annual growth of 6.9%. National investment across all sectors reached 1,010.6 trillion rupiah during the period.
Solar can support industrial demand
Government-cited programs include a solar power plan targeting overall capacity of 100 gigawatts-peak. The initial phase, launched in August, comprises 14 projects in six provinces totaling approximately 5.3 GWp. The authorities also envisage progressively replacing diesel-powered plants representing nearly 13 gigawatts of capacity with solar installations.
The scale of these targets highlights investment potential, but also the need to sequence projects. Solar can provide competitive energy when resources and infrastructure are suitable. Its variable output nevertheless requires stronger networks, flexibility solutions and, in some cases, storage. Converting diesel plants must account for supply continuity and the needs of island or remote areas.
The transition could also contribute to local processing. Demand for components, engineering, construction and maintenance can support Indonesian suppliers and develop technical skills. To obtain these benefits, industrial policies must preserve equipment quality and prevent local-content targets from excessively slowing project deployment.
From attractiveness to measurable results
Downstream industrial investment represented nearly one-third of recorded flows in the first half. This momentum can strengthen local added value if projects create skilled jobs, improve capabilities and connect to cleaner energy. Conversely, industrial expansion relying on carbon-intensive electricity or saturated networks can increase economic and environmental costs.
Investor decisions will therefore depend on regulatory predictability, electricity access and infrastructure availability. The government must coordinate permits, connections and generation offers while ensuring stable rules for energy producers and intensive users. Data-center needs must be incorporated into long-term planning rather than treated as isolated requests.
The convergence of energy and digital activity is an opportunity for Indonesia, provided investment is connected to electricity-system capabilities. Solar deployment, grid modernization and planning for new data centers must advance together. Success will be measured by the country's ability to supply reliable energy to industry and the digital sector while progressively reducing the carbon intensity of growth.
