Indonesia’s Ministry of Energy and Mineral Resources has announced an estimated IDR3000 trillion (USD179 billion) investment requirement to achieve full reliance on renewable-energy-based electricity. The amount covers capital for power plant construction, substations, transmission networks, distribution infrastructure, and other supporting systems. The ministry noted that mobilising the necessary financing will require cooperation across government, utilities, financiers, and the private sector.
Under State Utility PLN’s Electricity Supply Business Plan (RUPTL) 2025–2034, Indonesia plans to add 69.5 GW of new generation capacity, 47,758 circuit-km of transmission lines, and 107,950 MVA of substations. Clean-energy sources will account for 76 percent (52.9 GW) of the planned additions, including 42.6 GW of renewable energy and 10.3 GW of energy-storage systems. The remaining 16.6 GW will come from fossil-fuel-based power plants.
The energy transition is driven by Indonesia’s estimated 3,500 GW renewable-energy potential and the need to reduce reliance on fossil fuels. The Ministry of Energy and Mineral Resources and PLN are leading the implementation of the clean-energy roadmap, which targets large-scale capacity expansion, improved grid reliability, and long-term sustainability. The government reiterated the importance of multi-stakeholder collaboration to meet investment needs and deliver national energy goals.
