ArcelorMittal and EDF have signed a long-term Nuclear Power Production Allocation Contract for ArcelorMittal’s sites in France.

Under the agreement, EDF will allocate a share of the capacity of its operating nuclear fleet for a period of 18 years, securing ArcelorMittal with a long-term supply of low-carbon electricity.

Reiner Blaschek, CEO of ArcelorMittal Europe – Flat Products, said: “We welcome the signing of this Nuclear Power Production Allocation Contract with EDF.

“This agreement will enable us to supply our French sites over the long term with low-carbon electricity, a key factor for the future competitiveness of our steel produced in France.”

The latest agreement builds on a letter of intent signed between the two in 2024.

Béatrice Bigois, executive director in charge of the Customers, Services, and Territories Division at EDF Group, added: “This nuclear power production allocation contract illustrates the commitment of EDF teams over the past several months to provide industrial players with low-carbon, competitive electricity available over the long term.

“By supporting ArcelorMittal, a key player in steel production, we are contributing to the decarbonisation of industry and to energy sovereignty.”

The first deliveries began on 1 January 2026.
