Indonesia aims to add 69.5 GW of new power capacity between 2025 and 2034

The Ministry of Energy and Mineral Resources of Indonesia has unveiled the Electricity Supply Business Plan (RUPTL) of the national power utility PT PLN over the 2025-2034 period. Under the RUPTL 2025-2034, it aims to add 69.5 GW of new installed capacity in Indonesia, of which around 76% would come from renewables and storage systems (batteries and pumped-storage hydropower). In the first five years (2025-2030), 27.9 GW of new capacity should be built, including 12.2 GW of renewables, 9.2 GW of gas-fired power plants, 3.5 GW of coal-fired power plants (that are already under construction) and 3 GW of storage systems. Another 37.7 GW of renewable and storage capacity should be installed between 2030 and 2034, along with 3.9 GW of thermal (coal- and gas-fired) power plants.  Overall, the plan aims to install 17.1 GW of solar, 11.7 GW of hydropower, 7.2 GW of wind, 5.2 GW of geothermal and 0.9 GW of bioenergy. In addition, two small nuclear reactors, each rated 250 MW, should be built in Sumatra and Kalimantan. 

The power transmission network will also be expanded, as the government targets nearly 48,000 km of circuits and 108,000 MVA of substation capacities throughout Indonesia. Through the Village Electricity Program (Lisdes), the government aims to electrify 5,758 villages, with the construction of a power plant with a capacity of 394 MW and the connection of electricity to around 780,000 households. 

Total investments are estimated at IDR 2,967.4tn (US$182bn) but around 73% of the power plants should be developed in partnership with private companies or by independent power producers (IPPs) and only 27% should be developed by the PT PLN group. The RUPTL 2025-2034 aims to align with Indonesia's efforts to achieve the Net Zero Emission (NZE) target by 2060.
