Nuclear Power Could Slash Your Electric Bill. In Poorer Countries, the Same Deal Could Be a Debt Trap

Nuclear power's economics contain two things that are both true and that pull in opposite directions. Built the way South Korea, and to a lesser extent China, actually build it, nuclear is among the cheapest reliable sources of electricity available, cheap enough to genuinely offset a country's long-term energy costs. Built the way the US and UK have built it in their most recent projects, it is among the most expensive infrastructure a government can commission. And the financing model most developing countries are currently using to access nuclear power at all, heavily debt-financed, vendor-owned deals with Russia's Rosatom, carries real fiscal exposure that is worth examining plainly rather than either dismissing or catastrophizing.

The cost gap between "done well" and "done badly" is not small

The IEA and OECD Nuclear Energy Agency's 2020 joint cost survey found overnight construction costs (a standard industry metric excluding financing costs) ranging from $2,157 per kilowatt in South Korea to $6,920 per kilowatt in Slovakia, with China at roughly $2,500 per kilowatt. South Korea's Kepco used the same standardized reactor design to build the four-unit Barakah plant in the UAE, starting from zero prior nuclear experience in that country, at a turnkey cost of roughly $3,800 per kilowatt, still dramatically below Western benchmarks. By contrast, the US Vogtle 3 and 4 expansion, the only new reactors completed in the US in decades, came in at a total cost of roughly $35 billion for 2,234 megawatts of capacity, or somewhere north of $15,000 per kilowatt once financing costs are included, nearly double its own already-revised $25 billion estimate and more than seven times South Korea's per-kilowatt cost for comparable technology. The UK's Hinkley Point C, still under construction, is now projected at roughly £48 billion in 2026 prices for 3,260 megawatts, almost double its originally approved cost, and ranks second-worst on a per-megawatt basis among all nuclear plants built globally since 2000; only Vogtle costs more.

The pattern behind the gap is fairly well understood in the engineering literature: South Korea and China build reactors as a standardized fleet, using the same design repeatedly with an experienced, continuously employed workforce and supply chain. The US and UK, by contrast, went roughly two decades between new nuclear projects, meaning each new plant effectively restarts an atrophied skills base and supply chain from near scratch, a dynamic EDF acknowledged directly by opening a dedicated welders' training academy for Hinkley Point C specifically because the UK's domestic nuclear welding skills had lapsed.

For developing economies, the "easy" path to nuclear power runs through Russian financing, and that comes with real strings attached

Because most developing countries lack South Korea's decades of standardized build experience or China's domestic reactor-manufacturing base, the fastest route to nuclear power for many of them has been vendor-financed deals with Rosatom, Russia's state nuclear conglomerate, which has signed preliminary agreements with roughly 40 countries and currently has overseas construction commitments exceeding $100 billion, much of it funded through cheap loans from Russian state banks, per Oxford Institute for Energy Studies research.

The specific terms vary by country but follow a recognizable pattern. Bangladesh's Rooppur plant carries a total cost of $12.65 billion, with 90 percent, $11.38 billion, funded by a Russian government loan; Russia retains ownership structured such that Bangladesh cannot capture full electricity revenue from the plant for 20 years starting in 2027, according to Foreign Policy Research Institute analysis. Turkey's Akkuyu plant, roughly $25 billion, uses a Build-Own-Operate model in which Rosatom itself owns the plant and finances construction at 3 percent interest over 22 years. Egypt's El-Dabaa plant, roughly $30 billion, is about 85 percent financed through a Russian state loan. Africa's broader nuclear pipeline, spanning multiple countries at earlier planning stages, totals an estimated $105 billion in prospective projects, according to industry analysis, with vendor financing remaining the most commonly proposed solution to the upfront capital problem specifically because most African governments' existing sovereign debt loads make raising that scale of capital independently genuinely difficult.

Rosatom itself is not in fully stable financial condition to be everyone's lender of last resort: the company's own leadership announced a nearly 50 percent cut to its investment program in 2026 citing "poor economic conditions," and Oxford's analysis puts Rosatom's net debt-to-equity ratio at 69 percent with total debt exceeding $25 billion, raising real questions about how reliably the company can deliver on its full pipeline of roughly 40 country agreements.

This is a real fiscal exposure, not an inevitability

It is worth being precise about what the debt risk actually is. It is not that nuclear power itself is unaffordable, South Korea's own cost data disproves that directly. It is that the specific financing structure many developing countries are currently using, concentrated debt to a single foreign state lender, often paired with foreign ownership of the asset itself for one to two decades, creates a form of fiscal and strategic exposure that a country building the same technology through its own state-backed development bank, multilateral financing, or a domestically-controlled build-and-own model would not carry to the same degree. India's experience with its Kudankulam plant, built with a loan exceeding $3 billion from Russia's now-sanctioned Vnesheconombank, illustrates the risk concretely: continuing to service that loan during Russia's war in Ukraine puts India in the position of indirectly financing a combatant it has otherwise tried to stay neutral toward, a genuinely awkward position that has nothing to do with nuclear technology and everything to do with who financed it and on what terms.

China is pursuing a broadly similar playbook in parts of the developing world through its own state-backed lending, including reported majority ownership stakes in national grid infrastructure in at least one Southeast Asian country, suggesting the debt-and-ownership dynamic here is not specific to Russia so much as it is a structural feature of vendor-financed megaproject lending to capital-constrained governments generally.

The other side of the ledger: what happens to oil exporters, and to US consumers, if nuclear actually displaces gas

There is a second, less-discussed piece of the "offsetting energy costs" claim worth examining directly: nuclear power's cost advantage matters most as a hedge against natural gas, since gas-fired plants set the marginal price of electricity in most competitive US power markets, per the EIA's own Annual Energy Outlook. Natural gas supplied 43.4 percent of US electricity generation in 2024, nuclear just 18.1 percent, meaning gas price swings, like the ones tied directly to Gulf oil and gas disruptions during the Iran war, pass through to electricity bills far more than nuclear's stable, fuel-cost-insensitive output does. The EIA's own modeling finds nuclear generation only expanding meaningfully in its "Low Oil and Gas Supply" scenario, where gas prices rise enough to make new nuclear economical, meaning nuclear's practical role in "offsetting" costs is really about reducing exposure to exactly this kind of gas-price shock, not a wholesale replacement of gas in the current outlook, where nuclear's share is projected roughly flat to declining through 2050 in most cases.

If that hedge did scale up meaningfully, though, the money involved doesn't just vanish, it moves away from the economies that currently depend on oil and gas purchases for their government budgets. That dependency is severe and concentrated: oil accounts for more than 40 percent of government revenue in at least 17 countries worldwide, and in Iraq and Libya specifically, it runs between 70 and 90 percent of government income, according to a September 2026 energy-transition risk analysis. Nigeria's federal government draws roughly 80 percent of its revenue from oil, and 90 percent of its export earnings. The same analysis modeled what an accelerated global shift away from oil demand would do to these budgets directly: an 87 percent decline in Algeria's oil revenue, and a fall of more than 60 percent in Nigeria's, declines that the report's authors explicitly warned could destabilize state capacity in exactly the countries least able to absorb the shock, with knock-on security implications the researchers said extended well beyond the oil sector itself, even as they stressed their findings were not an argument for slowing the shift away from fossil fuels, just for taking the transition's costs on exporters seriously rather than ignoring them.

That is the honest shape of the tradeoff. A world that buys meaningfully less oil and gas for electricity generation is a world where the US and other large importers get some insulation from the kind of price shocks a war in the Strait of Hormuz can trigger overnight. It is also a world where a specific, identifiable set of oil-dependent developing economies, several of which are already managing high debt-service burdens, Angola and Mexico both spend more than a quarter of government revenue just servicing existing debt, lose a large share of the revenue their state budgets are currently built on. Neither side of that ledger cancels the other out, and both are real.

The honest read

Nuclear power's cost data genuinely supports the case that it can meaningfully offset long-term energy costs, but only under the standardized, fleet-based, experienced-workforce conditions that South Korea and China have demonstrated and that Western one-off megaprojects have conspicuously failed to replicate. Separately, and just as genuinely, the debt-heavy, foreign-owned financing structure that most developing countries are currently using to access nuclear power at all carries real, documented fiscal exposure, concentrated foreign debt, multi-decade foreign ownership of critical infrastructure, and geopolitical entanglement with the lender's own conflicts, that is a function of how these specific deals are structured, not an unavoidable feature of nuclear power as a technology. And a third, separate dynamic sits underneath both: any real-world success in offsetting fossil-fuel-driven energy costs for importing countries like the US comes, mechanically, at the expense of government budgets in the oil-exporting developing world that current forecasts suggest are the least prepared to absorb that loss. None of these three claims cancels out the others. Collapsing them into either "nuclear is the answer" or "nuclear will bankrupt the developing world" loses the more specific, more actionable finding underneath: the technology, the financing structure, and the demand-side ripple effects are three separate problems, and only the first has been convincingly solved, by exactly one country's build strategy so far.

FAQ

Is nuclear power actually cheaper than other energy sources? It depends heavily on how it's built. South Korea's standardized fleet approach produces reactors at roughly $2,150 per kilowatt, competitive with or cheaper than many alternatives. The US and UK's recent one-off projects have cost seven to nine times that per kilowatt, making the technology's cost-effectiveness highly dependent on build strategy rather than being a fixed property of nuclear power itself.

Why do developing countries rely so heavily on Russian financing for nuclear plants? Most lack the decades of standardized nuclear construction experience that keeps costs low, or the domestic capital to self-finance a multi-billion-dollar project, making vendor-financed deals, historically dominated by Rosatom, one of the few readily available paths to nuclear power. Rosatom has signed preliminary agreements with roughly 40 countries and holds over $100 billion in overseas construction commitments.

How much debt do these nuclear financing deals typically involve? Costs vary by project but the foreign-financed share is typically 85 to 90 percent of total project cost: Bangladesh's Rooppur plant ($12.65 billion total) is 90 percent Russian-loan-financed; Egypt's El-Dabaa plant (roughly $30 billion) is about 85 percent Russian-loan-financed.

Does Russia actually own some of these nuclear plants outright? In some cases, yes, under Build-Own-Operate arrangements. Turkey's Akkuyu plant is owned and operated by Rosatom itself. Bangladesh's Rooppur deal is structured so Russia retains rights that prevent Bangladesh from capturing full electricity revenue for 20 years starting in 2027.

Is Rosatom financially stable enough to complete all of its committed projects? There are real questions about this. Rosatom announced a nearly 50 percent cut to its investment program in 2026 citing weak economic conditions, and carries a reported net debt-to-equity ratio of 69 percent with total debt exceeding $25 billion, which has already stalled some prospective projects in Central Asia.

If nuclear power reduces fossil fuel demand, who actually loses out financially? Oil-exporting developing economies whose government budgets are heavily dependent on oil revenue. At least 17 countries draw more than 40 percent of government revenue from oil, and in Iraq and Libya specifically that figure runs 70 to 90 percent. One 2026 risk analysis modeled an accelerated shift away from oil demand producing an 87 percent decline in Algeria's oil revenue and a more than 60 percent decline in Nigeria's.

Does reducing fossil fuel demand actually lower electricity prices for US consumers? It can act as a hedge against gas-price volatility specifically, since gas-fired plants set the marginal price of electricity in most US power markets. But the EIA's own modeling projects nuclear's share of US generation staying roughly flat to declining through 2050 under most current scenarios, expanding meaningfully only if gas becomes significantly more expensive or scarce, so the hedge is real but conditional rather than a guaranteed, near-term price cut.
