Indonesia - World Nuclear Outlook Report
Nuclear policy and outlook
Under President Prabowo Subianto, nuclear has been elevated to a formal pillar of national energy policy and is explicitly written into the Electricity Supply Business Plan (RUPTL 2025-2034) of PLN - Indonesia's state-owned electricity utility. In September 2025 Prabowo signed the revised National Energy Policy (KEN), setting Indonesia’s energy transition pathway to net-zero emissions by 2060. The policy designated nuclear energy as part of the new national energy mix, with targets for nuclear to contribute 0.4-0.5% by 2032, 2.8-3.4% by 2040, 6.8-7.0% by 2050 and 11.7-12.1% by 2060 .
The Indonesian National Energy Council targets 8 GWe of installed capacity to come from nuclear power plants in 2035, increasing to 45-54 GWe in 2060, with an intermediary target of 21 GWe in 2050.
The Electricity Supply Business plan includes proposals for 500 MWe (2×250 MWe) from 2032 in Sumatra/Bangka Belitung and West Kalimantan. PT ThorCon Power Indonesia has initiated the licensing process for the construction of a power plant based on its advanced molten salt reactor technology. A site at Kelasa island, located in Central Bangka, is being investigated to host the plant.

Readiness Assessment
Indonesia combines a stronger institutional and technical base than most newcomer nuclear countries, but has made little progress towards its 2032 target for 500 MWe capacity and longer-term goals.
| Country Category | Candidate |
|---|---|
| Policy Framework Readiness | Moderate Nuclear is now embedded in national policy. 500 MWe is scheduled for 2032 and a much larger 2060 programme is envisaged. |
| Institutional & Infrastructure Readiness | Moderate Indonesia has an experienced independent nuclear regulator, research reactors, nuclear fuel and waste facilities; however, its commercial power capabilities remain incomplete. |
| Programme & Project Development Readiness | Moderate PLN has begun site preparation work and ThorCon has regulatory approval to undertake site evaluation, but there is still no selected technology or site approval for the RUPTL projects. |
| Target Achievability | Low Initial nuclear deployment is planned, but the 2032 target is highly unlikely to be met and a 45 GWe-plus fleet by 2060 would require a rapid transition to serial deployment. |
