Slovakia buys out Czech stake in new nuclear project company

Czech state-owned utility ČEZ has sold its 49% stake in Slovakia's nuclear development company JESS to Slovakia's state-owned JAVYS for EUR189 million. ČEZ said the move reflects global practice: new nuclear plants are built under state direction. Slovakia's Prime Minister Robert Fico said full state ownership would accelerate construction of a new reactor at Jaslovské Bohunice, allowing Slovakia to use the permits and preparation work JESS has accumulated since its formation in 2009. The US and Slovakia signed a cooperation memorandum earlier this year for a 1,200 MWe American nuclear unit. Slovakia already relies on nuclear for more than half its electricity and is completing Mochovce 3 and 4, which will push nuclear to 77.5% of the country's generation mix when fully operational.

Where this fits

This is a sovereignty play. Slovakia is consolidating state control of a decades-long nuclear project precisely to move faster, not slower. The country has chosen firm power as the backbone of its grid: it is betting on nuclear, not on weather-dependent renewables plus gas firming plus transmission overbuild. The decision to buy out a Czech partner and move to single-state ownership shows how seriously Slovakia treats energy independence. New nuclear in Central Europe is not a sideshow; it is a core national infrastructure decision treated as such.

What it means

Australia is watching this from the opposite corner. Slovakia is building a second new reactor while Australia, by law, cannot build any nuclear plant at all. That legal ban is not a statement about nuclear's cost or safety; it is a political choice made decades ago and never revisited. When a sovereign state needs firm electricity and chooses nuclear to secure it, Australia has no legal option to do the same. This is not a disagreement about technology. It is a gap in strategic capacity that widens each year the grid leans harder on weather-dependent supply.
