A group of prominent Polish entrepreneurs have committed half a billion złoty to a project building small modular reactors based on BWRX-300 technology, according to an announcement from SGE, the company developing the programme in Poland.
The investors include InPost chief executive Rafał Brzoska, Krzysztof Pawiński, Michał Wypychewicz, Dariusz Gałęzewski, Dominik Doliński, Mati Staniszewski, Michał Brański and Bruno Wejchert, Bankier.pl reported on Wednesday.
BWRX-300 is a reactor with an output of roughly 300 megawatts electric, designed specifically for mass production. The technology descends from the boiling water reactor family, of which 67 units have been built worldwide. Forty of these remain operational in the United States, Japan, Sweden, Finland and Spain.
Six sites under consideration
SGE, the firm leading the Polish deployment of the technology developed by GE Vernova Hitachi Nuclear Energy, has outlined an ambitious plan to construct as many as 26 BWRX-300 reactors at six locations across the country. Sites being assessed include Włocławek in central Poland, Stawy Monowskie and Stalowa Wola in the south-east, according to the company statement.
The domestic investment comes on top of foreign backing already secured. SGE said it has obtained commitments from international investors totalling 1.35 billion złoty, bringing the combined capital raised for the programme to more than 1.8 billion złoty.
Small modular reactors are seen as a faster and more flexible route to nuclear power than large conventional plants. Their compact, factory-built design is intended to lower construction costs and shorten build times, making them attractive to countries seeking to diversify energy sources and cut carbon emissions.
What this means for Poles in Poland
Poland is racing to reduce its dependence on coal, which still generates the majority of the country’s electricity, and has placed nuclear energy at the centre of its energy transition strategy. The government has already committed to building a large nuclear plant on the Baltic coast in partnership with American firm Westinghouse, with the first reactor due online in the mid-2030s.
The SMR programme backed by Polish billionaires represents a parallel track. If successful, the smaller reactors could come online more quickly and in multiple locations, potentially stabilising electricity prices and improving energy security. For households and businesses, a diversified energy mix may help moderate future bill increases and reduce exposure to fossil fuel price swings.
The involvement of high-profile domestic investors signals growing confidence in the commercial viability of nuclear power in Poland. However, the project remains in early stages. Regulatory approval, site preparation and construction will take several years, and operational reactors are unlikely before the end of this decade at the earliest.
Anyone interested in following the programme’s progress or potential local impacts—particularly residents near the proposed sites—should monitor announcements from SGE and Poland’s National Atomic Energy Agency, which oversees nuclear licensing and safety.
