When Energy Becomes Economic Infrastructure

For decades, energy was positioned as one sector within economic development, standing alongside industry, agriculture, trade, and transport. Its benchmarks were relatively simple: oil and gas production capacity, gigawatts of power plants built, or the electrification ratio achieved. This perspective has carried Indonesia through various phases of development. However, the world is now moving much faster than when that paradigm was first constructed. The digital revolution, artificial intelligence, electric vehicles, industrial downstreaming, and the transition to a low-carbon economy have altered the relationship between energy and economic growth. Energy no longer merely supports economic activity; it now determines whether that activity can take place at all. In other words, energy is no longer just an economic sector—it has transformed into economic infrastructure.

This shift in perspective is not merely a play on words. It determines how Indonesia designs its development policies, directs investment, and builds national competitiveness for decades to come. In the 20th century, nations raced to build motorways, ports, railways, and airports. That infrastructure connected production centres to markets, accelerated logistics, opened new industrial zones, and boosted national productivity. Toll roads shortened distribution times, ports smoothed international trade, and airports opened access to new growth centres. Now, entering the 21st century, physical infrastructure remains important but is no longer the sole determinant of competitiveness. Amidst the digital economy and green industrialisation, a reliable energy system has become the primary factor determining where investment will flow.

This phenomenon is visible across the globe. Global-scale data centres no longer choose locations solely based on cheap land or proximity to ports. They seek regions capable of supplying large amounts of electricity, stable twenty-four hours a day, and with increasingly low carbon emissions. The same applies to the semiconductor industry, electric vehicle battery manufacturing, mineral smelters, and artificial intelligence-based computing facilities. All these sectors share a single requirement: a reliable energy supply. Without stable electricity, investments worth billions of dollars can lose their appeal. This means the quality of a nation’s energy system is now a key indicator of its economic competitiveness.

Indonesia is at a very opportune moment to capitalise on this change. The government is accelerating mineral downstreaming, building an electric vehicle ecosystem, strengthening the battery industry, developing special economic zones, and attracting investment in data centres and high-tech manufacturing. Although originating from different sectors, all these strategic agendas rest on the same foundation: sufficient, reliable, affordable, and increasingly clean energy. It is here that the old paradigm begins to lose its relevance. Discussions on the energy sector have often stopped at power plant construction. Whenever a new project is announced, public attention almost always focuses on the size of the generation capacity to be built. Yet, power plants are only the starting point. The economic value of electricity is truly created when that energy can be efficiently channelled to industrial zones, new growth centres, ports, special economic zones, manufacturing hubs, and cities that drive the national economy.

Therefore, transmission and distribution networks now hold strategic significance equal to the national toll road system. If toll roads connect producers to markets, then energy networks connect resources to productivity. Toll roads accelerate the flow of goods, while energy networks accelerate the flow of investment, industrialisation, and innovation. Without a strong network, no matter how large the power plant, it will not yield optimal economic benefits. This paradigm shift becomes even clearer when examining the characteristics of Indonesia’s future energy sources. Unlike fossil fuel-based plants, which were often built near electricity consumption centres, most new and renewable energy sources are located far from industrial zones and demand centres. The largest hydropower potential lies in Kalimantan and Papua. Geothermal energy is spread across Sumatra, Java, Sulawesi, and Nusa Tenggara. Solar energy is developing almost everywhere in Indonesia, while wind potential is found in Sulawesi, Nusa Tenggara, and several coastal areas. All this potential does not automatically become economic strength. Added value is only created when that energy can be channelled to locations requiring large amounts of electricity. This means Indonesia’s challenge is no longer simply finding new energy sources, but building national energy connectivity. In this context, investment in transmission networks becomes as important as investment in power generation. In many countries, building electricity grids has even become the top priority. Without adequate transmission, the energy transition will proceed slowly because clean energy sources cannot reach electricity consumption centres. Indonesia faces a more complex challenge than many other nations because it is an archipelagic country with scattered electricity systems that are not yet fully interconnected. Meanwhile, electricity demand is expected to rise sharply alongside economic growth, urbanisation, digitalisation, mineral downstreaming, and the emergence of data centres.
