The Czech State Office for Nuclear Safety has awarded a permit to the Czech national power utility ČEZ for the development of two new 1.2 GW units at the Dukovany nuclear power plant. The state-owned power utility is currently planning to build only one reactor at Dukovany, and the permit for two units will allow ČEZ to review its plans.
ČEZ already operates four VVER-440 reactors at the Dukovany nuclear power plant (2,040 MW) and two VVER-1000 reactors at the Temelín plant (2,160 MW). Replacing the older reactors with new units is viewed as crucial for the country’s energy security, as the four Dukovany reactors are expected to be shut down permanently between 2035 and 2037. In July 2020, the Czech government signed agreements with ČEZ for the expansion project. The agreements encompassed the overall general framework of the €6bn project and its initial phase. The project will benefit from an interest-free loan and power from the new nuclear reactor will be sold at a fixed tariff. Consumers would make up the gap if that price is higher than wholesale market prices. ČEZ is expected to set a preferred list of suppliers by 2022 and to sign a contract with one supplier by 2024. Construction should start in 2029, and commissioning is expected in 2036.
