TotalEnergies signs a nuclear production allocation contract with EDF to supply its refining and chemicals sites

The momentum behind nuclear production allocation contracts is continuing. By signing such a contract with EDF, TotalEnergies is securing a major share of the electricity supply for its industrial sites in France, illustrating the growing role of these mechanisms in the strategy of large electricity-intensive companies.

The development of nuclear production allocation contracts (CAPN) among major industrial players continues. On 27 March, TotalEnergies announced the signing of such an agreement with EDF. Concluded for a period of twelve years, it aims to cover a significant share of the electricity needs of the Group’s refining and chemical sites in France. According to available information, it would secure around 60% of their supply, representing nearly 400 MW.

In a LinkedIn post, TotalEnergies CEO Patrick Pouyanné highlighted the industrial rationale behind this commitment: “It will enable us to supply our domestic refining and chemicals sites with competitive and low-carbon electricity.” He also referred to “a win-win agreement for our two industrial groups.” “For TotalEnergies, it secures over the long term a large part of the electricity supply for our French industrial sites, which are major electricity consumers. For EDF, it allows risks and costs of nuclear production, which is essential to the national energy transition, to be shared.”

More concisely, EDF CEO Bernard Fontana welcomed “an agreement with TotalEnergies serving energy and industrial sovereignty.”

CAPNs, a competitiveness tool for industry

Since the end of the ARENH mechanism on 1 January 2026, CAPNs have gradually become a central instrument for industrial competitiveness. Their principle is to offer industrial consumers direct access to a share of EDF’s nuclear generation at a price stabilised over the long term.

In return, clients agree to share certain risks, notably those related to the availability of the nuclear fleet. This mechanism thus makes it possible to strike a balance between security of supply, economic visibility and contribution to low-carbon electricity.

A momentum already underway with several major groups

With TotalEnergies, EDF adds another major name to the list of industrial companies engaged in this type of contract. The utility has already concluded similar agreements with several major players, including ArcelorMittal for a period of 18 years, Lafarge and Orano for a duration of 10 years, as well as the data centre operator Data4. ■
