A consortium of Polish billionaires and business leaders has committed 500 million złoty to a project building small modular reactors in Poland, according to an announcement from SGE, the company developing the programme.
The investors include some of Poland’s most prominent entrepreneurs: Rafał Brzoska, founder of parcel delivery firm InPost; Krzysztof Pawiński, chairman of Maspex; Michał Wypychewicz; Dariusz Gałęzewski; Dominik Doliński; Mati Staniszewski; Michał Brański; and Bruno Wejchert.
According to Bankier.pl, SGE has also secured 1.35 billion złoty from foreign investors, bringing total capital raised for the venture to over 1.8 billion złoty.
Technology and scale
The project centres on the BWRX-300, a small modular reactor designed for serial production with a generating capacity of approximately 300 megawatts electric. The technology comes from GE Vernova Hitachi Nuclear Energy and is part of the boiling water reactor family.
Globally, 67 units of the parent BWR design have been built, with 40 still operating in the United States, Japan, Sweden, Finland and Spain. The smaller BWRX-300 variant is intended to be easier to construct and finance than traditional large-scale nuclear plants.
SGE’s programme envisages the construction of up to 26 BWRX-300 reactors at six locations across Poland. Among the sites under development are Włocławek in central Poland, Stawy Monowskie, and Stalowa Wola in the south-east.
Poland’s nuclear ambitions
Poland has long relied on coal for the majority of its electricity generation but is seeking to diversify its energy mix to meet climate commitments and reduce dependence on fossil fuels. The country currently has no operating nuclear power stations.
Alongside the large-scale Westinghouse nuclear plant planned for the Baltic coast in Pomerania, small modular reactors are seen as a complementary strand of Poland’s nuclear strategy. Their smaller size and modular construction are intended to speed deployment and lower upfront costs.
Wednesday’s announcement signals growing private-sector confidence in Poland’s nuclear plans. The involvement of well-known business figures lends both financial weight and public visibility to the SMR project.
What this means for Poles in Poland
The investment marks a concrete step towards diversifying Poland’s electricity supply and reducing reliance on coal-fired power, which has implications for energy security and air quality. If the project proceeds as planned, it could create jobs in construction, engineering and operations at the six planned sites over the coming years.
For households and businesses, successful deployment of small modular reactors would contribute to a more stable and lower-carbon electricity grid. However, timelines for SMR construction remain uncertain, and regulatory approvals, grid connection and public consultation processes will all need to be completed before any reactor can come online.
Those living near proposed sites—Włocławek, Stawy Monowskie and Stalowa Wola among them—should expect further announcements on planning, environmental assessments and community engagement. Official updates on the programme are published by SGE and Poland’s Ministry of Climate and Environment.
