Indonesia and the Momentum for ASEAN Energy Cooperation
Southeast Asia is entering a new chapter of economic development. The region is no longer just an emerging market, but one of the world’s most dynamic centres for manufacturing, the digital economy, investment, and global supply chains. Alongside this, energy demand is rising sharply. New industrial zones, data centres, electric vehicles, urbanisation, and manufacturing transformation all require a larger, more reliable, and cleaner electricity supply. In this context, the energy transition can no longer be viewed solely as an emissions reduction agenda. It has become an economic strategy, an industrial strategy, an investment strategy, and a regional security strategy. A country that can provide clean energy at competitive prices will be better placed to attract investment, strengthen export competitiveness, and build the industries of the future.
Indonesia is in a highly strategic position to take on this role. This is not only because it is the largest economy in ASEAN, but because it possesses a combination of advantages rarely found elsewhere: a large domestic market, diverse energy resources, abundant renewable energy potential, strategic mineral reserves, a geographic position connecting the region, and strong regional diplomatic experience. These advantages become increasingly relevant as ASEAN moves towards an economy that is ever more dependent on electricity. Data centres, electric vehicles, low-carbon smelters, electronics manufacturing, the semiconductor industry, and the digital economy all require a far more reliable electricity system than was needed a decade ago. In the future, the quality of electricity supply will be one of the main indicators of economic competitiveness.
Therefore, the discussion on energy transition needs to shift from merely replacing energy sources to building a comprehensive energy system. Renewable energy is important, but it will not deliver maximum impact without strong transmission networks, energy storage, energy efficiency, digitalisation of systems, regulatory certainty, and competitive financing. This systems-based approach is a shared need for Indonesia and ASEAN. Electrification will continue to increase, but its success depends heavily on the quality of electrical infrastructure. A country that can deliver a clean, stable, and efficient electricity system will become a magnet for regional investment. Conversely, a country that lags in building its energy system risks losing industrialisation opportunities.
Indonesia actually has a very strong foundation. Solar energy potential is spread across almost the entire archipelago. The country’s geothermal resources are among the largest in the world. Hydropower still has significant room for expansion. Bioenergy can grow alongside the strength of the national agricultural sector. Wind energy has prospects in various coastal and island regions. Beyond this, Indonesia also holds reserves of nickel, copper, bauxite, and various strategic minerals that are key raw materials for global energy transition technologies. However, resource wealth does not automatically translate into leadership. What matters is the ability to convert potential into a productive system. This is where Indonesia’s major task lies. Strengthening transmission networks, interconnecting systems, building energy storage, improving project quality to make them bankable, and developing domestic industry must all proceed simultaneously. With such a foundation, Indonesia can become not just a user of clean energy technology, but also a producer, exporter, and a vital node in the regional supply chain.
In the regional context, one of the most strategic initiatives is the ASEAN Power Grid. The idea of building a cross-border electricity network has long been on ASEAN’s agenda. However, its urgency is now far greater. Electricity interconnection is not merely a project of submarine cables or transmission lines, but an instrument to strengthen energy security, enhance system efficiency, and expand regional electricity trade. That said, building the ASEAN Power Grid is not just about physical infrastructure. The bigger challenges lie in harmonising regulations, establishing electricity trading mechanisms, ensuring financing certainty, setting technical standards, sharing investment costs, and synchronising national energy policies. Without a strong governance foundation, the regional network will struggle to develop optimally.
For Indonesia, these developments present a huge opportunity. Its geographical proximity to Singapore and Malaysia, combined with the clean energy potential in Sumatra, Kalimantan, and the Riau Islands, opens up the possibility of making Indonesia a supplier of low-carbon electricity as well as a hub for green industrial growth in the region. The development of Batam, Bintan, and Karimun is an interesting example. This area is strategically positioned to connect clean energy, data centres, digital manufacturing, logistics, and regional connectivity within a new economic ecosystem. If designed properly, the BBK area could become a laboratory for Indonesia-ASEAN energy cooperation as well as a model for green industrialisation in the region. However, cross-border energy cooperation must not be interpreted as a reduction of national energy sovereignty. On the contrary, if designed with the right principles, regional electricity trade can become a new instrument of Indonesia’s economic diplomacy. The key is simple: domestic needs remain the priority, industrial value-added is built within the country, and every cross-border project must deliver tangible benefits to the public, the business sector, and national development. With this approach, exporting clean electricity is not merely an energy transaction, but a way for Indonesia to expand its economic influence in the region.
