Commission raises concerns over support for new Dukovany units

The European Commission has published details of its formal investigation into the Czech support model for the construction of two new nuclear units at Dukovany. Although the investigation was officially launched at the end of last year, more detailed information has only now been published. The Commission has several objections to the proposed support. In its view, the proposed support may be too generous. The Czech Republic has also failed to provide sufficient details to assess its impact on the market. This is the European Commission's initial position on the proposed support, and the final form of the state aid will be subject to further negotiations.

The European Commission published details of the proceedings concerning the Czech notification of support for two new units at Dukovany at the turn of the month. The Czech Republic notified the support on 2 October 2025; according to the decision, it is a broader model than the previously approved support for the standalone fifth unit. The assessment now covers two units, a changed investor model and a more extensive support "package".
