IN Brief:
- TotalEnergies has filed authorisation documents for the 1.5GW Centre Manche Énergies offshore wind project.
- The Normandy project is expected to generate around 6TWh of electricity annually if delivered as planned.
- Offshore wind scale is increasing demand for grid connection, subsea cables, installation capacity, and European equipment supply chains.
TotalEnergies has filed the authorisation application for the Centre Manche Énergies offshore wind project off Normandy, advancing a 1.5GW development that would become one of France’s largest renewable energy projects.
The project is being developed with RWE and is planned more than 40km off the Normandy coast. It is expected to generate around 6TWh of electricity each year, equivalent to the annual consumption of more than one million homes, with production aligned to the grid connection schedule for the early 2030s.
Centre Manche Énergies was awarded through a French offshore wind tender and carries an expected investment value of around €4.5bn. Construction is expected to involve up to 2,500 people over a three-year period, linking the project to a wider industrial supply chain across ports, marine engineering, electrical infrastructure, foundations, installation vessels, and grid connection works.
The authorisation filing moves the development into a more detailed phase of permitting and engineering. Projects of this size need alignment between turbine selection, foundation design, offshore substations, inter-array and export cables, grid interfaces, environmental controls, marine logistics, and port capacity before construction can begin.
TotalEnergies has also set out commitments covering training, industrial participation, recycling, and biodiversity funding. The project includes targets for reuse, recycling, or repurposing across major components, including blades, towers, nacelles, and generator magnets, reflecting the increasing focus on lifecycle management in offshore wind procurement.
Offshore wind development across Europe is being shaped by the same physical constraints. The delayed decision on the Morgan and Morecambe transmission assets and Boskalis’ order for a new 24,000-tonne cable-lay vessel show how strongly project delivery depends on cable manufacturing, vessel availability, grid interfaces, and consenting certainty.

France has been building its offshore wind sector at a different pace from the UK, Germany, the Netherlands, and Denmark, but the scale of Centre Manche Énergies shows the market moving into larger project zones. At 1.5GW, the development is not only a generation asset; it is a major grid and marine infrastructure programme with long procurement timelines and multiple technical interfaces.
Grid connection remains one of the central delivery factors. Large offshore wind farms bring concentrated volumes of variable generation ashore, requiring transmission capacity, substations, cable routes, environmental permissions, and coordination with existing network development. The early 2030s connection schedule will determine when the project can convert installed capacity into delivered electricity.
The project’s circularity commitments also reflect a maturing offshore wind sector. Blade recycling, magnet recovery, tower reuse, and nacelle component repurposing are becoming more visible as first-generation wind assets move towards end-of-life decisions. New projects are increasingly expected to show how materials will be managed over the full asset lifecycle.
Industrial participation is another important element. European governments want offshore wind to support domestic jobs, port activity, and component supply chains, while developers need bankable procurement, stable policy, and reliable access to specialist equipment. Those aims can only align if permitting, grid connection, and supply-chain investment progress together.
Centre Manche Énergies now moves through the authorisation process with a scale that places it among Europe’s major offshore developments. Its progress will be a useful indicator of how quickly France can convert offshore wind ambition into connected generation and supporting industrial capacity.
