A Czech court has blocked the Czech power utility CEZ from signing a contract worth at least €16bn with South Korea's Korea Hydro & Nuclear Power (KHNP) to build two new nuclear reactors at the Dukovany nuclear power plant, located in southern Czechia. This follows a complaint from the French utility EDF. In October 2024, UOHS had already put a temporary block on the conclusion of a contract with KHNP, following a first challenge from EDF and Westinghouse.
EDF 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. CEZ was originally supposed to sign a contract with KHNP on 7 May 2025, but the Czech court will not allow the signing until the court has handled the new complaint from EDF. 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.
