The South Korean energy group Korea Hydro & Nuclear Power (KHNP) has signed a final contract to build two new nuclear reactors at the Dukovany nuclear power plant, located in southern Czechia, following the lifting of a court injunction that had blocked the deal. The final contract was signed between KHNP and Elektrarna Dukovany II, a subsidiary of the Czech power utility CEZ.
In early May 2025, a Czech court had blocked CEZ from signing the contract with KHNP, worth at least €16bn, following a complaint from the French utility EDF. EDF had filed a complaint against Czech competition regulator UOHS in late April 2025 after UOHS rejected its appeal over a tender to pick a supplier for the two nuclear reactors. KHNP was originally chosen to deliver its APR1000 reactor, rated 1,055 MWe, in July 2024. The first reactor is still expected for completion by 2036.
Czechia aims to rise the share of nuclear power from 35% in 2013 to between 46% to 58% by 2040 (40% in 2023). The country gets electricity from the four VVER-440 units at Dukovany, which began operating between 1985 and 1987, and the two VVER-1000 units in operation at Temelín, which came into operation in 2000 and 2002.
