## Is Indonesia Actually Building a Nuclear Power Plant by 2032?

Indonesia's Ministry of Energy and Mineral Resources has set a target of having the country's first nuclear power plant operational by 2032 at the earliest, with Semesak Island — an uninhabited 300-hectare site off the coast of West Kalimantan Province in Borneo — emerging as the government's preferred location. The target date is aggressive by any measure, and the site selection has not yet received formal presidential approval. The country is reviving plans that date to the mid-1990s under President Suharto, plans that stalled after the March 2011 earthquake and tsunami triggered the Fukushima Daiichi meltdown.

The scale of Indonesia's ambition is significant: the government has stated a target for nuclear energy to account for up to 12.1 percent of the primary energy mix by 2060, with an installed capacity of 35 to 42 gigawatts. That would represent one of the largest nuclear buildout commitments in the developing world. The government has explicitly stated a preference for [small modular reactors](https://smrintel.com/glossary/foak), describing the technology as allowing factory assembly and transport to site — language that closely mirrors [Rosatom State Nuclear Energy Corporation's](https://smrintel.com/companies/rosatom) standard SMR pitch.

## Semesak Island: What the Site Offers and What It Doesn't

Semesak Island sits approximately 900 meters off Sungai Raya Village in Bengkayang Regency, West Kalimantan. The government's stated rationale for preferring it over the other leading candidate — the island province of Bangka Belitung — centers on its uninhabited status and its reported position outside an active seismic zone.

The national government plans to expropriate 300 hectares covering the island itself and a buffer zone on the opposite shore. The regent of Bengkayang Regency, Sebastianus Darwis, has publicly endorsed the project, framing it as an industrial catalyst and a potential power source for Nusantara, Indonesia's new capital under construction in East Kalimantan Province. Darwis also mentioned ambitions to export electricity.

However, seismic risk remains the central technical objection. Indonesia sits on the Pacific Ring of Fire, and Fabby Tumiwa, executive director of the Institute for Essential Services Reform, warned that new active faults have been discovered across the country in recent years. He stated flatly that there is "nothing safe" about siting nuclear plants in Indonesia, and questioned the economic feasibility of the program independently of the safety debate. The country's history of earthquakes and volcanic eruptions — the same geological context that made Fukushima politically decisive for Indonesian policy in 2014 — has not changed.

What has changed is the political framing. Indonesia formally reclassified nuclear from a "last option" energy source to a "strategic choice" last year. Deputy Minister of Energy and Mineral Resources Yuliot told an international nuclear forum in Jakarta in December that the new energy strategy would "explicitly" require nuclear energy to balance the energy mix and meet decarbonization targets.

## Rosatom's Position and Japan's Competing Interests

The geopolitics of Indonesia's nuclear ambitions are already in motion. Rosatom Director General Alexey Likhachev met Indonesian President Prabowo Subianto in May in Jakarta, offering support for construction. Indonesia's stated preference for SMR technology aligns with Rosatom's existing product portfolio and its aggressive pursuit of nuclear export agreements across the Global South.

Japan is also moving. The Economy, Trade and Industry Ministry signed a memorandum of understanding with Indonesia's energy ministry in March to assist with nuclear energy introduction. The timing is notable: Japan's own industry ministry proposed last June replacing two to five aging reactors by the 2040s and 11 to 14 by the 2050s — the first time a numerical target had been set post-Fukushima. Tokyo's domestic policy normalization appears to be unlocking its willingness to export nuclear cooperation agreements more aggressively.

The question for Indonesia's counterparties is which vendor technology eventually gets selected. The source material does not name a specific reactor design or vendor beyond the general SMR preference and Rosatom's engagement. No formal procurement has been announced, and presidential approval for even the implementing organization has not yet been granted — a material gap between the 2032 target and current administrative reality.

## The Credibility Problem with 2032

Nuclear engineers and project finance analysts will immediately flag the timeline as extremely compressed. As of this reporting, Indonesia has not completed site selection, has not established the implementing organization, and does not have presidential approval to do either. Zainal Arifin, acting head of the Nuclear Energy Regulatory Agency, said earlier this year that "it is a good moment for Indonesia to make a decision" — language that implies a decision has not yet been made, not that construction is imminent.

[First-of-a-kind](https://smrintel.com/glossary/foak) nuclear projects in markets without existing nuclear infrastructure routinely take longer than initial government projections, often by a decade or more. The United Arab Emirates, which had substantial sovereign wealth and institutional capacity, required roughly 15 years from policy decision to first power. Indonesia's regulatory framework, grid infrastructure, and nuclear workforce are at an earlier stage than the UAE's was at a comparable milestone.

The 35–42 GW target by 2060 requires sustained commitment across multiple presidential administrations and funding cycles. Neither the source nor available public record indicates a financing structure has been proposed for even the first unit.

## What This Means for the SMR Market

Indonesia joining the list of active emerging-market nuclear programs — alongside Poland, Saudi Arabia, the Philippines, and others — has real implications for SMR vendor strategy. A 35–42 GW target, even if achieved at a fraction of that scale, represents a meaningful addressable market. Rosatom's early engagement gives it a structural advantage, but Japan's MOU and the broader Western interest in countering Russian nuclear influence in Southeast Asia suggest competitive vendor processes are possible.

For uranium and [enrichment](https://smrintel.com/glossary/enrichment) market analysts, Indonesia's long-term 2060 target is too distant to affect near-term contract pricing. The 2032 first-unit date, if achieved, would be more relevant — but that timeline has yet to be grounded in the kind of regulatory and procurement milestones that would make it credible to fuel suppliers.

The broader regional signal is clear: Southeast Asia's nuclear ambitions are accelerating across multiple countries simultaneously, and Rosatom is working aggressively to be the default partner.

## Frequently Asked Questions

**Where will Indonesia build its first nuclear power plant?**
The Indonesian government's preferred site is Semesak Island, an uninhabited island located approximately 900 meters off Sungai Raya Village in Bengkayang Regency, West Kalimantan Province on Borneo. Bangka Belitung island province is the other leading candidate. No site has been formally selected pending presidential approval.

**When does Indonesia plan to have its first nuclear plant operating?**
The Ministry of Energy and Mineral Resources has stated a target of 2032 at the earliest. However, as of mid-2026, Indonesia has not yet established a nuclear implementing organization, completed site selection, or begun regulatory licensing — making the timeline highly compressed by historical FOAK standards.

**What type of reactor is Indonesia planning to build?**
Indonesia has explicitly stated a preference for small modular reactors, citing factory assembly and transportability as key advantages. Rosatom has engaged the Indonesian government directly, and SMR technology is prominently referenced in official statements, though no specific reactor design or vendor has been selected through a formal procurement process.

**What is Indonesia's long-term nuclear energy target?**
The government targets nuclear energy accounting for up to 12.1 percent of the primary energy mix by 2060, with an installed capacity of 35 to 42 gigawatts.

**What are the main concerns about Indonesia's nuclear plans?**
Critics cite two primary issues: seismic safety, given Indonesia's location on the Ring of Fire and the discovery of new active faults, and economic feasibility. Fabby Tumiwa of the Institute for Essential Services Reform has stated the program is not economically viable and carries unresolved safety risks. Local fishing communities near Semesak Island have also expressed concerns about radiation and potential displacement.
