Poland Wants SMRs Badly — Here's Why That Matters for Europe
The country that runs on coal more than any other EU member is betting its energy future on small modular reactors, and the decisions it makes next will echo across the continent.
Poland is an unusual place to find optimism about nuclear energy. It’s a country whose electricity grid still leans more heavily on coal than any other European Union member — coal was the main source of electricity at 52.8 percent in 2025, the highest proportion by far in the EU, down from 70 percent just a few years ago but still a number that makes Brussels twitch. And yet, right now, Poland is positioning itself to become the SMR capital of Europe. Not as a vague aspiration — as a concrete, funded, site-selected, agreement-signed industrial strategy.
That’s not nothing. That’s actually a very big deal.
The push for small modular reactors in Poland isn’t a moonshot or a press-release fantasy. In February 2026, GE Vernova Hitachi Nuclear Energy and Orlen Synthos Green Energy signed the Poland Generic Design Agreement in Washington D.C., committing to advance the Polish generic design of the BWRX-300 small modular reactor. The signing was attended by the U.S. Deputy Secretary of Energy and Poland’s own Minister of Energy. That’s not a handshake at a trade show. That’s a strategic alignment between two governments.
So why does Poland want SMRs so badly? And what does that mean for the rest of Europe? Pull up a chair.
The coal problem Poland can’t ignore
You cannot understand Poland’s nuclear ambitions without first sitting with the coal numbers. They are genuinely staggering. In 2024, Poland paid 112 billion PLN for fossil fuel imports — and its overall dependence on energy imports has grown from 29 percent to 45 percent over the past decade. That’s not energy security. That’s energy vulnerability wearing a very expensive coat.
The consequences show up in electricity prices, too. In 2024, the average day-ahead spot price in coal-dependent Poland was €100 per MWh, compared to €58 per MWh in nuclear-focused France. Polish industry pays nearly double what French competitors pay for electricity. When you’re the fifth-largest manufacturing economy in the EU, that gap doesn’t stay an abstraction for long — it shows up in factories closing and supply chains relocating.
And coal isn’t going to stick around much longer anyway, regardless of what anyone wants. The capacity contracts that prop up Poland’s aging coal fleet are expiring, and up to 8 GW of coal capacity may exit the system as those contracts end. Here’s what makes this genuinely difficult:
Coal still accounts for over half of Poland’s electricity, so any gap is massive
Renewables alone can’t provide the firm, always-on baseload coal currently supplies
Grid storage infrastructure is underdeveloped for a full variable-energy transition
New gas capacity carries its own import dependency problems
That’s the energy trap Poland finds itself in. SMRs, in the eyes of the government and the country’s major industrial players, are the most credible way out.
What Poland is actually building — and how fast
The scope of Poland’s SMR ambitions is, frankly, jaw-dropping once you look at the numbers. The number of announced SMRs from various Polish entities currently exceeds 100, with the majority — 76 reactors — planned by Orlen Synthos Green Energy (OSGE), a joint venture between state-owned fuel giant Orlen and one of Europe’s largest chemical companies, Synthos. 🏗️
The first site has been chosen. Poland’s first small modular reactor will be constructed in Włocławek, and the licensing agreement grants OSGE full access to the BWRX-300 reactor technology developed in the U.S. Orlen’s CEO put it plainly: Poland will host the first BWRX-300 in Europe. That’s a significant claim, and right now, it’s a credible one.
It’s worth noting just what the BWRX-300 actually is. It’s a 300 MWe water-cooled, natural circulation SMR with passive safety systems — meaning it can shut itself down safely using gravity and natural convection without requiring active mechanical intervention. That feature is not a marketing line; it’s a genuinely meaningful engineering distinction that makes the reactor more tolerant of operator error and power outages.
Other players are circling Poland too, hungry for a piece of the market: 🌐
KGHM, the copper mining giant, plans a six-reactor NuScale VOYGR plant with a combined 462 MWe of output
Rolls-Royce SMR has received backing from Polish industrial group Industria to progress a Decision in Principle
Last Energy and EDF both have Polish partnerships in development
The public, remarkably, is on board. Polls from November 2024 conducted by the Polish Ministry of Industry found that 93% of Poles are in favour of building nuclear reactors in Poland, and 80% are ready to accept an installation close to their homes. ☢️ In most Western European countries, those numbers would be politically impossible. In Poland, they reflect a pragmatic population that’s been cold and expensive-to-heat for long enough to welcome any credible alternative.
Does this mean the reactors will be built on schedule? Almost certainly not, if history is any guide. But the political will, the public support, and the industrial partnerships are all simultaneously present in a way that’s rare.
The European dimension
Here’s the angle that doesn’t get enough attention: what Poland does with SMRs will shape what the rest of Europe can do. 🌍
Poland isn’t operating in a vacuum. The Czech Republic, Denmark, Romania, and Estonia are actively supporting SMR development. The Netherlands has Equinix signing letters of intent for SMR-powered data centers. Bulgaria, Croatia, Slovakia, and Slovenia have all expressed interest. But none of them has moved as fast, or with as much industrial capital behind it, as Poland.
If OSGE successfully builds the first Western commercial BWRX-300 in Włocławek, the entire European SMR market changes. You get a licensed reference design, a proven construction methodology, a trained workforce, and — not least — a supply chain that other European customers can plug into. The Canadian reference project at Ontario Power Generation’s Darlington site matters, but a European reference project on European soil, using European contractors, would matter more for European deployment timelines.
There’s an EU-level policy angle here too. During the Joint European Forum on IPCEIs on 9 April 2025, a design phase for an Important Project of Common European Interest focused on innovative nuclear technologies was launched. That’s EU industrial policy finally treating advanced nuclear as something worth backing with collective European money, not just tolerating politely. Poland’s participation in that mechanism could unlock funding and regulatory coordination that makes the whole European SMR build-out faster.
Think about what you’d want to know: would it matter to you if SMR electricity were available to European manufacturers at French-style prices rather than Polish-style prices? Because that’s roughly the kind of industrial competitiveness gap that’s in play here.
The obstacles are real, and nobody should pretend otherwise
In the interest of not writing cheerleader copy for a technology that hasn’t yet proven itself at commercial scale in the West, let’s be honest about the headwinds. 🔧
The regulatory picture in Poland is messy. The current legal framework treats SMRs identically to large nuclear power plants, which means the investment process is long and complicated, and the main barriers include high investment costs, lengthy permitting procedures, and a lack of trained personnel. The government knows this and is working on dedicated SMR regulations, but “working on” is not the same as “has delivered.”
Timelines are also routinely optimistic in first-of-a-kind nuclear projects. Experts at the Polish Economic Institute believe the first SMR should be expected around the mid-2030s, and installed capacity is unlikely to exceed 5 GW until the mid-2040s — partly due to the certification processes underway in the U.S. and Canada. There’s also the awkward political subplot: Poland’s president has shown a tendency toward vetoing energy transition legislation, which creates uncertainty even when the government is moving in the right direction.
And the waste question doesn’t disappear just because the reactors are smaller. SMRs produce more nuclear waste per unit of energy than large reactors due to neutron leakage, and higher fuel enrichment means spent fuel that’s more radioactive. These are engineering facts, not anti-nuclear talking points. Poland will need to solve them.
None of that means the project is doomed. It means it’s hard, which anyone who’s been paying attention already knew.
Why this is the story to watch
There’s a version of the next fifteen years in which Poland becomes the first European country to successfully commercialize Western SMR technology at scale. In that version, the supply chain effects radiate outward, the regulatory templates get copied, and the EU’s 2050 carbon neutrality target becomes dramatically more achievable for coal-dependent member states from Bulgaria to Czechia. 🚀
There’s another version in which delays compound, costs overrun, and a few cancelled projects dent investor confidence across the continent for a decade.
Poland is, right now, at the fork between those two paths. Polish Energy Minister Miłosz Motyka was explicit about the stakes at the February 2026 signing: “Poland has the potential to become a European leader in SMR technology. To ensure a stable, zero-emission power system and predictable market conditions for industry, we are advancing in parallel both large-scale nuclear power plants and small modular reactor technology.”
That dual-track approach — large plants and SMRs, not one instead of the other — is probably the right strategy. It avoids betting everything on a technology that’s still proving itself while also ensuring that SMRs don’t get sidelined as a niche curiosity. Whether execution matches strategy is the question that will define Polish — and by extension, European — energy for the next generation. 💡
What do you think: does Poland’s coal legacy make it the most motivated country in Europe to get SMRs right, or is that precisely what makes the scale of transformation so daunting? Drop a reply — this one is worth debating.
