State electricity company PT PLN has revealed that Indonesia is set to build nuclear power plants (NPP) with a total capacity of up to 7 gigawatts (GW) by 2040 as stipulated in the draft of the country’s long-term power supply roadmap (RUPTL).

“This is still a draft, so the modeling is still in progress,” PLN President Director Darmawan Prasodjo told a hearing with energy, mineral resources and environment Commission XII of the House of Representatives (DPR) on Tuesday, August 26, 2025.

He cited that the 7 GW projection is an extension of the 2025–2034 RUPTL, which already includes plans for two nuclear plants of 250 megawatts (MW) each. He stressed that the larger plan requires comprehensive discussions on nuclear power in Indonesia’s energy legislation under the Ministry of Energy and Mineral Resources (ESDM).

“This requires strategy, government policy, institutional capacity building, and political support, as climate change demands affordable energy prices,” he said.

According to him, affordable energy will boost economic growth, create jobs, attract investment, and improve public welfare.

“The state must be present here. PLN is only the executor of government policy. The 500 MW in the 2025–2034 RUPTL is just the first step before we move toward a broader plan of around 7 GW by 2040,” Darmawan said.

Meanwhile, the ESDM Ministry has a longer-term vision of 35 GW of nuclear power capacity by 2060, which could require the construction of more than 30 NPP units nationwide.

“By 2060 we aim for 35 GW. If we use land-based models, that means around 30 units. Nuclear is one of the solutions for base load power in addition to renewable energy,” Eniya Listiani Dewi, Director General of New, Renewable Energy, and Energy Conservation (EBTKE) at the ESDM ministry, said at the Human Capital Summit 2025, on June 4, 2025.

The latest RUPTL also sets out that two NPPs of 250 MW each will be built in South Sumatra and West Kalimantan, with both plants expected to be on-grid by 2032.

Eniya further noted that the ministry is coordinating with the State Secretariat, the Administrative and Bureaucratic Reform Ministry, and other agencies to establish a Nuclear Energy Program Implementation Organization (NEPIO) − a national body tasked with accelerating nuclear power development in Indonesia.

Most recently, the ESDM Ministry confirmed that it had received official proposals from five countries, including Canada and Russia, to build nuclear power plants in Indonesia.

“We are still reviewing the proposals. We have already met with Canada and Russia,” ESDM Minister Bahlil Lahadalia said at the State Palace, Jakarta, on Monday, August 25, 2025.

Bahlil emphasized that the government has not yet chosen a specific nuclear technology design, as all proposals are still under evaluation.
