Opening of in-depth investigation into State aid to two new nuclear units in Czechia published in the OJ

The Commission has published in the Official Journal (OJ) the opening of the in-depth investigation into Czechia’s plans to support the construction and operation of two new nuclear units at the Dukovany site. The decision was taken on the 22^nd of December last year.

Czechia plans to support the investment through a low-interest State loan covering construction costs, a 40-year two-way contract for difference (Cfd) to stabilise revenues, and a mechanism to protect the operator against policy changes.

The Commission’s preliminary assessment has raised concerns over the design, proportionality and competitive impact of the proposed aid package. The Commission will now examine whether this combination of measures risks granting more aid than necessary, weakens incentives for efficient operation, or unduly distorts competition, including by reinforcing ČEZ’s market position.

Interested third parties can submit comments until the 27June 2026. Clayton & Segura can help you to prepare and submit your comments.
