Bangladesh will not build any more large nuclear reactors after the US$12.65 billion Rooppur plant begins operation, the country’s power and energy minister confirmed in July 2026. The decision marks a strategic pivot toward Western-supplied small modular reactors even as the Russian-built project nears its long-delayed start.
The Rooppur plant, on the Padma River, will supply up to 15% of the nation’s electricity by 2028. The shift away from big reactors signals both the financial strain of the project and a bid to reduce dependence on a single vendor.
Bangladesh will not pursue further large-scale nuclear plants, the country’s power and energy minister told reporters this month. The statement closes a chapter on a decade-old strategy, even as the Rooppur plant—a 2,400-megawatt Russian-designed project on the Padma River—edges toward operation.
The government, in power since February 2026, inherited Rooppur from its predecessor. The main construction contract with Russia’s Rosatom cost around US$12.65 billion, and delays from the pandemic, sanctions, and the war in Ukraine have pushed completion past the original target.
In local currency, the cost has climbed nearly 25% as the taka weakened. The minister’s answer has been to start early talks with Rolls-Royce Holdings Plc and Chinese manufacturers for reactors of 300 to 400 megawatts that could be built along riverbanks faster than any large plant.
The result is a tension that shapes the country’s nuclear future: a delayed, over-budget mega-project moves toward the finish line while the government that will operate it is already looking past it.
The minister who saw the bill and turned away
“We will not go for large-scale plants anymore because there are huge liabilities,” Iqbal Hassan Mahmood, Bangladesh’s power and energy minister, said in July. The comment was more than a fiscal admission. It opened a market for Western small modular reactors at the moment a Russian-supplied plant was supposed to seal Bangladesh’s energy independence.
Rooppur’s two VVER-1200 reactors are now expected to start generating power with the first unit in 2027, and the second a year later, according to the International Atomic Energy Agency’s most recent project review. Once both are online in 2028, the plant will meet about 15% of Bangladesh’s current electricity demand.
The delay has been expensive beyond the construction site. “A timely completion would have not only avoided this massive cost escalation but would have also helped us trim our fossil fuel import bill,” said Md Shafiqul Islam, professor of nuclear engineering at Dhaka University. In the absence of Rooppur, Bangladesh remained exposed to the oil and gas price spikes that followed the Iran war.
Md. Zahedul Hassan, managing director of state-owned Nuclear Power Plant Co Bangladesh Ltd, defended the project’s economics. When judged against supply security and long-term fuel-cost predictability, he said, “it’s very much competitive.”
The calculation shifts when the burden is measured in who carries it. The project’s upfront cost falls on the Bangladeshi state and power consumers, because no electricity has been delivered yet. Local communities around the Padma River site will live with nuclear waste handling, emergency planning, and regulatory capacity that determine the real long-term risk.
Toby Dalton, co-director of the nuclear policy programme at the Carnegie Endowment for International Peace, warned that enthusiasm for nuclear can push developing economies into risky choices. “I don’t think any developing economy wants to be a laboratory for a technology that hasn’t been proven and demonstrated elsewhere,” he said. That warning sits uneasily alongside a government that is now shopping for small reactors before the large one proves itself.
“The recent geopolitical conflicts—Iran and Russia-Ukraine—have shown that a scarcity of resources hurts poorer countries more than rich ones,” said R. Srikanth, head of the energy, environment and climate change programme at the National Institute of Advanced Studies in Bengaluru. “That strengthens the case for nuclear in emerging economies.” The evidence is, partly, the fact that Bangladesh is moving forward at all.
The scale of Rooppur against its regional benchmarks explains why the government is already looking smaller.
The liability that changed the conversation
What forced the pivot was not ideology but arithmetic. Rosatom offered the credit line and the technology, but the IAEA safeguards framework and the long repayment terms did not erase the obligation. Rooppur alone will not insulate Bangladesh from the next fuel crisis; the International Energy Agency’s latest data shows that the power system still depends heavily on fossil generation. The emissions profile, while not pinned to a single 2026 national statistic, remains stubbornly high by IEA indicators.
Under its updated nationally determined contribution, Bangladesh links lower-emissions power growth to energy security. But the gap between that policy aim and execution is wide: financing plans for new small reactors, an independent nuclear regulator, and a reliable fuel-supply chain are still unresolved.
“The Rooppur plant will ensure Bangladesh doesn’t need to build any new baseload capacity in the next five to seven years,” said Shafiqul Alam, lead Bangladesh analyst at the Institute for Energy Economics and Financial Analysis. That, he argued, creates space for renewables and grid modernization. It also means the next big decision—whether to accelerate SMR procurement—will land before Rooppur’s second unit even starts.
The shift also carries a geopolitical undercurrent. Rosatom’s business model ties customers to long-term fuel servicing and credit, which gives Moscow influence over operating conditions long after construction ends. The minister’s openness to Rolls-Royce and Chinese vendors suggests a desire to spread that dependence. “For developing economies, nuclear power is also a tool for long-term national development,” Rosatom said in an emailed statement, emphasising industrialisation and expertise. The country that built Bangladesh’s first plant is not the one being asked to build its second.
The first fuel loading will determine whether Rooppur becomes a symbol of energy independence or a monument to a strategy already left behind.
Beyond the headline
The Bigger Picture
Rooppur is testing whether a developing country can buy energy sovereignty without also buying decades of vendor dependence. The real mechanism is not technology choice alone, but whether a state can manage financing, sanctions exposure, and nuclear oversight well enough to turn one project into a durable power system rather than a prestige asset.
The Power Behind It
Rosatom’s leverage comes from financing, fuel, and long-term servicing, not just reactor design. That gives Moscow influence over timelines and operating conditions even when the plant is physically on Bangladeshi soil, which is why the project matters as much for geopolitical alignment as for electricity supply.
The Reach
For Western nuclear suppliers, Bangladesh’s turn toward SMRs opens a market that depends on one mechanism: whether financiers and regulators can separate smaller reactors from the reputational drag of a giant delayed project. The implication is a chance to compete with Russian state-backed export power in a market where credibility may matter as much as price.
A strategic opening for three audiences
Bangladesh’s nuclear pivot gives different actors in the West distinct signals and timelines. Here is what each should watch.
- Western SMR investors and technology firms
Bangladesh’s early talks with Rolls-Royce and Chinese manufacturers create a brief window for Western vendors to shape procurement standards. Track the power ministry’s formal expression of interest for 300–400 MW plants, expected by late 2026, and monitor whether IAEA pre-licensing support is requested—that would signal a serious shift in regulatory ambition.
- Non-proliferation and energy security analysts
The transition from a single Russian supplier to a multi-vendor approach changes nuclear governance needs. Check the IAEA’s Bangladesh safeguards page and country-specific nuclear security updates for any new bilateral agreements that govern fuel supply and spent-fuel repatriation. The safeguards architecture built for Rooppur will need to stretch to a new set of reactors.
- Climate finance and development banks
Bangladesh’s updated nationally determined contribution frames nuclear power within energy security, not explicitly as a decarbonisation pillar. Development finance institutions considering SMR co-financing should consult the UNFCCC NDC registry to see whether the nuclear option is being formally claimed as a climate mitigation measure, and whether the cost assumptions match the likely timelines.
Explainer
- Rooppur
- Bangladesh’s first nuclear power plant, located on the Padma River in the country’s west. It has two VVER-1200 reactors with a combined planned capacity of 2,400 megawatts, built by Russia’s Rosatom under a financing agreement that covers construction and initial fuel loads. The project has become a test case for deploying large reactors in a non-nuclear developing nation.
- Rosatom
- Russia’s state atomic energy corporation, acting as technology provider, main contractor, and creditor for the Rooppur plant. It offers export customers long-term credit and fuel-supply arrangements, creating a model that ties the buyer to Russian servicing for decades and gives Moscow leverage over nuclear programmes in multiple emerging economies.
- Small modular reactor
- A nuclear reactor design typically generating less than 400 megawatts, built in factories and assembled on-site. Bangladesh’s government is exploring SMRs as a faster, lower-capital alternative to large plants, citing reduced construction liability and the ability to place units along riverbanks. Western vendors such as Rolls-Royce are competing for these early developing-world contracts.
- IAEA safeguards
- The system of inspections, material accountancy, and verification applied by the International Atomic Energy Agency to ensure nuclear materials are not diverted to weapons use. Bangladesh’s Rooppur plant operates under IAEA safeguards, which also influence how Western export-credit agencies and insurers treat future nuclear cooperation with Dhaka.
