The energy company TotalEnergies, through its wholly owned project vehicle Centre Manche Energies, has formally lodged an application to obtain the Single Authorization for a 1.5 GW offshore wind development sited off the coast of Normandy. This submission follows the earlier award of the project by the French State and represents a substantive procedural advance for what the developer describes as the country’s largest renewables initiative. The dossier bundles technical work, environmental studies and a first-pass engineering layout designed to satisfy regulatory standards and set a clear path toward construction.
The filing was prepared after a sequence of marine and terrestrial investigations and reflects continued engagement with authorities and regional stakeholders. In the application, the developers included a comprehensive environmental impact assessment informed by seabed and ecological surveys, stakeholder consultations and iterative exchanges with government departments. Project leadership emphasises that permitting now moves into an examination phase, while consultations with local officials, environmental groups and seafaring communities will continue to refine siting and mitigation measures.
Application and regulatory steps
Filing for the Single Authorization starts a formal review by the competent administrative bodies that will assess technical compliance, environmental safeguards and the project’s integration into maritime uses. The application contains a preliminary design and a planned installation programme that describe how turbines, foundations and export cables are to be deployed more than 40 km offshore. The company has committed to an iterative process: as the dossier is examined, additional studies or adjustments may be requested and ongoing dialogue with stakeholders will inform final approvals and conditions attached to authorization.
Surveys, assessments and public consultation
Included in the submission are the results of geophysical, geotechnical and ecological surveys that underpin the environmental analysis. The environmental impact assessment synthesizes those technical findings and integrates contributions collected during regional consultations. Public meetings and targeted briefings with fishermen, local municipalities and conservation groups are designed to reduce conflicts at sea and shape monitoring programs. The developer has signalled it will continue collection of data and stakeholder input while the authorities undertake their formal examination of the file.
Project scale and regional benefits
At 1.5 GW of capacity and an expected annual generation of around 6 TWh, the Centre Manche project is sized to supply renewable electricity equivalent to more than one million households. The scheme sits at scale for France and, once built, is projected to require an investment on the order of €4.5 billion. During the main construction phase—planned to last approximately three years—the development is expected to mobilize as many as 2,500 workers, drawing on local labour with existing offshore wind expertise and creating a sustained programme of economic activity in Normandy and adjacent ports.
Economic footprint and industrial sourcing
Beyond direct employment, the developer intends to prioritise European manufacturers for key components such as wind turbines and export electric cables, providing industrial opportunities across supply chains. This sourcing preference aims to maximize regional and continental industrial participation while shortening logistics and supporting local fabrication yards and service companies. The project proponents argue that a focus on European suppliers will help anchor long-term maintenance and operations capacity onshore.
How the project aligns with TotalEnergies’ electricity strategy
Centre Manche fits within a broader shift at TotalEnergies toward assembling a competitive electricity portfolio that mixes large-scale renewables with flexible assets and storage. The company reports a substantial renewables footprint in France, consisting of hundreds of solar, wind, hydro and battery facilities that serve the electricity needs of millions of people. By the end of April 2026, TotalEnergies stated it holds nearly 36 GW of gross renewable generation capacity and has set ambitions to deliver over 100 TWh of net electricity by 2030, positioning projects like Centre Manche as material to those targets.
As the permitting timetable advances, the focus will remain on finalizing technical dossiers, deepening consultations and securing industrial partnerships that can translate the plan into on-the-water construction. If authorized, the development will represent both a major infrastructure investment for Normandy and a strategic element of the company’s pathway to scaling up large offshore wind capacity in France and Europe.
