According to Serbian Economist, Serbia has publicly returned to the idea of buying a minority stake in the Hungarian Paks II nuclear power plant project amid the official start of the main stage of construction of the plant in early February 2026, industry sources report.
On February 5, Hungary held a “first concrete” ceremony, pouring concrete into the foundation slab of the reactor building. According to IAEA standards, this is considered the official start date of construction and transfers the facility to the status of “nuclear power plant under construction.”
Belgrade is interested in acquiring a 5-10% stake in the Paks II project. It is expected that such a stake would give Serbia the right to a fixed share of electricity production and could become a long-term source of “base” low-carbon generation for domestic demand.
Paks II involves the construction of two new power units with VVER-1200 reactors (approximately 1,200 MW each). The project is being implemented with the participation of the Russian state corporation Rosatom under a 2014 intergovernmental agreement and is financed in part by a Russian state loan. The goal is to commission the new units in the early 2030s.
This is not the first time Serbia has expressed interest in participating in the project: in November 2024, Serbian President Aleksandar Vučić said that he had asked Budapest to consider selling Serbia up to 10% of the project and emphasized his willingness to pay for the share at market price, with the Hungarian side promising to look into the matter at the time.
