IN Brief:
- A French state-aid scheme with a maximum €63 billion budget will support eleven offshore wind projects.
- Fixed-bottom and floating developments will require coordinated generation, cable, substation, port, and transmission investment.
- France is targeting 15GW of offshore capacity by 2035 and 45GW by 2050.
The European Commission has approved a French state-aid scheme with a maximum budget of €63 billion to support the construction and operation of eleven offshore wind farms.
Operating over 25 years, the programme covers developments planned across France’s North Sea, Atlantic, and Mediterranean maritime areas. Approval under the Clean Industrial Deal State Aid Framework gives the French government a regulatory basis for long-term revenue support as it advances a substantially larger offshore generation pipeline.
The €63 billion ceiling represents the maximum potential expenditure across the life of the scheme rather than an immediate capital allocation. Final support costs will depend on the projects awarded contracts, their output, wholesale electricity prices, contractual terms, construction schedules, and operating performance.
France intends to reach 15GW of installed offshore wind capacity by 2035 and 45GW by 2050, establishing the technology as a major component of its electricity system alongside nuclear generation, hydropower, onshore renewables, and cross-border interconnection.
Around 10GW is being progressed through the combined AO9 and AO10 tender process, divided broadly between 5GW of fixed-bottom capacity and 5GW of floating wind across several maritime zones. The first awards are expected between late 2026 and early 2027.
Supply-chain resilience criteria derived from the EU Net Zero Industry Act will form part of the procurement process. Projects will consequently be assessed against industrial and sourcing considerations as well as price, creating additional requirements around equipment origin, manufacturing capacity, cyber security, and the resilience of critical components.
Generation awards require coordinated network delivery
Revenue support for the wind farms addresses only one part of the delivery programme. Offshore substations, array cables, export circuits, landfall works, onshore substations, reactive compensation, protection systems, and transmission reinforcement must all be completed in step with turbine construction.
Where grid works fall behind generation, completed turbines can remain constrained or unavailable despite the capital already committed offshore. Coordination between developers, equipment manufacturers, transmission planners, consenting authorities, ports, and marine contractors will therefore shape the effective commissioning date of each project.
Floating wind introduces further interfaces, particularly around dynamic cables that must accommodate platform movement over decades of operation. Anchoring arrangements, offshore joints, bend protection, seabed conditions, and electrical connection systems will require project-specific engineering, while ports need sufficient depth, quay strength, assembly space, and access to installation vessels.
Réseau de Transport d’Électricité will carry much of the responsibility for planning and delivering the associated transmission infrastructure. Standardised offshore platforms and cable systems could reduce repeated engineering, although differences in water depth, distance from shore, seabed geology, environmental constraints, and available connection points will continue to shape individual designs.
European cable factories and installation fleets are already serving offshore wind, interconnectors, and domestic reinforcement programmes. Manufacturing investment is increasing, but lead times for high-voltage cable, specialist joints, transformers, switchgear, and offshore installation vessels remain exposed to a concentrated supplier base.
France’s combined 10GW procurement round marked a shift away from smaller, project-by-project allocations. Larger and more regular tenders can provide manufacturers, ports, engineering consultancies, and network contractors with greater visibility when committing to factories, vessels, training, and local supply chains.
Longer visibility does not eliminate commercial pressure. Offshore projects across Europe have faced higher financing costs, equipment inflation, vessel shortages, revised turbine strategies, and delays in securing grid infrastructure. Development periods extending over several years also expose designs to changing equipment ratings and updated technical standards.
The French government is seeking an average award price below €100/MWh for the combined tender. Maintaining competition while incorporating resilience requirements will require bids that remain financeable through detailed design, procurement, and construction, rather than prices that prove untenable once supply contracts are negotiated.
Fixed-bottom and floating projects will progress at different speeds, and each will depend on a connection programme capable of matching its offshore construction schedule. A large state-aid envelope can support investment, but installed capacity will ultimately be determined by consented cable routes, manufacturing slots, available ports, contracted equipment, and energised transmission assets.
