The Slovak government has taken further steps toward developing a new nuclear power unit near the existing Bohunice nuclear power plant, reinforcing nuclear energy’s central role in the country’s long-term power strategy.
In May 2024, the government officially approved plans for a new 1.2 GWe nuclear unit at the Bohunice site. This was followed in September 2025 by cabinet approval of the wording for a proposed intergovernmental agreement with the United States covering the construction of a state-owned nuclear unit with a capacity exceeding 1,000 MW.
State-owned company JAVYS said the project involves a preliminary investment framework running into several billion euros, a long construction timeline, and an operational lifespan spanning several decades. As a result, financing conditions will play a decisive role in determining the project’s overall cost. JAVYS confirmed that the project has now entered its next preparatory phase, focused on establishing an optimal and long-term sustainable financing model.
Three bidders participated in the tender for financial advisory services, with the contract awarded at a value of €13.9 million ($16.17 million), excluding VAT. Under the agreement, Rothschild & Co will provide professional support to the Slovak state, particularly in structuring and defending the project’s financing model during European Union state aid procedures, applying best practices from major nuclear developments, and preparing the project for a smooth transition into the financing and implementation phases.
Rothschild & Co brings extensive experience in nuclear project financing, having previously advised on the UK’s Sizewell C project and new nuclear developments in the Czech Republic.
According to JAVYS, the partnership will strengthen Slovakia’s position in negotiations with the European Commission and with domestic and international financial partners. It is expected to improve transparency, clarity, and predictability of long-term costs while enabling responsible risk sharing, ensuring the country is well prepared for the next phase of project delivery.
Slovakia currently operates five nuclear reactors—three at Mochovce and two at Bohunice—which together generate around half of the country’s electricity. One additional reactor is under construction at Mochovce. Both nuclear power plants are operated by Slovenské Elektrárne.
