Question 4158 — energy and fuels

Summary

The industrial-port zone of Fos-sur-Mer concentrates industrial activities that consume a lot of energy and is experiencing growing electricity needs, linked in particular to the decarbonization of industrial processes and the development of new projects. More than 6 GW of connection requests have now been identified by 2030. To meet these needs and strengthen the security of the region's electricity supply Provence-Alpes-Côte d'Azur, RTE plans in particular the creation of an air link with two 400,000 volt circuits of approximately 65 kilometers between the substations of Feuillane, in Fos-sur-Mer, and Jonquières-Saint-Vincent, in Gard. As the Government has already indicated to Parliament, the studies carried out have confirmed the need for a new very high voltage axis; different technical solutions, particularly underground, were examined before choosing the current solution. The project is subject to close monitoring by the State, ongoing consultation and support with local authorities, economic players, the agricultural world, associations and residents. After a first public consultation in 2024 and the “Fos-Berre-Provence” public debate organized in 2025, the State began processing the declaration request in May 2026. of public utility filed by RTE. The commissioning of the link is currently estimated for 2029-2030. This strengthening of the network is part of the decarbonization strategy of the Fos-Étang de Berre area more broadly, supported in particular within the framework of France 2030 and the “Low carbon industrial zones” program. This mobilizes several complementary levers: energy efficiency, electrification of processes, low-carbon hydrogen, renewable and recovery energies as well as, where necessary, carbon capture. The Government thus remains fully mobilized to enable the development of the electrical infrastructure necessary for the decarbonization and reindustrialization of the area, while guaranteeing security of supply, compliance with environmental procedures and the close association of stakeholders in the sector. territory.
