Indonesia plans 69.5 GW new capacity by 2034

Indonesia’s Ministry of Energy and Mineral Resources has released its 2025–2034 Electricity Supply Business Plan, targeting 69.5 GW of new power generation capacity. Of this, 76 per cent will come from renewable sources and storage systems.

The plan aligns with Indonesia’s goal to reach net-zero emissions by 2060. It addresses rising electricity demand, especially in urban areas, and aims to modernise the energy mix.

In the first phase (2025–2030), 27.9 GW will be added. This includes 12.2 GW from renewables, 9.2 GW from gas, 3.5 GW from coal (mostly ongoing projects), and 3 GW in energy storage.

The second phase (2030–2034) will focus more on clean energy, adding 37.7 GW from renewables and storage, while limiting fossil fuel additions to 3.9 GW.

Solar will account for the largest share of new capacity at 17.1 GW, followed by hydropower (11.7 GW), wind (7.2 GW), geothermal (5.2 GW), and bioenergy (0.9 GW). Indonesia will also introduce nuclear energy with two 250 MW small modular reactors in Sumatra and Kalimantan.

To support the capacity expansion, nearly 48,000 km of transmission lines and substations with a total capacity of about 108 GW will be developed across the country.
