France: TotalEnergies Files for Authorization of Its Giant Centre Manche Energies Offshore Wind Project

Key Terms

offshore wind technical

Offshore wind is wind turbines and related facilities installed in the sea or large lakes to generate electricity from stronger, steadier winds offshore. For investors, it matters because these projects are large, long-lived infrastructure investments that can provide steady revenue under long-term power contracts or government support, but also carry big up-front costs, construction and maintenance risks, and dependence on policy and grid connections — like building a factory on the water that sells power instead of goods.

environmental impact assessment technical

An environmental impact assessment is a process that evaluates how a planned project or development might affect the natural environment, including air, water, land, and wildlife. It helps identify potential risks and suggests ways to minimize harm before the project begins. For investors, it matters because projects with significant environmental risks may face delays, increased costs, or restrictions, affecting their overall viability and returns.

battery storage technical

Battery storage is a system that stores electricity in large rechargeable batteries so power can be used later, like a reusable fuel tank for the grid. Investors care because it smooths out when energy is available vs. when it’s needed, can lower costs, create new revenue from selling stored power at peak times, and reduce reliance on unpredictable energy sources, affecting utility and clean-energy company valuations.

ccgt technical

A CCGT, or combined-cycle gas turbine, is a type of power plant that generates electricity by burning natural gas in a turbine and then using the waste heat to run a secondary steam turbine—like a car that reuses exhaust heat to squeeze out extra mileage. Investors care because CCGTs are relatively efficient, flexible and lower‑emission than older plants, so their operating costs, fuel price sensitivity and permitting or carbon rules can materially affect power company revenues and asset values.

PARIS--(BUSINESS WIRE)-- Eight months after being awarded the project by the French State, TotalEnergies’ wholly owned project company Centre Manche Energies has officially applied for the Single Authorization of the 1.5 GW offshore wind farm, which will be sited off the coast of Normandy. This marks a significant milestone in the development of France’s largest renewables project.

“We are delighted to have filed for authorization and to have reached this major milestone for Centre Manche Energies. We would like to thank our technical partners and regional stakeholders, as well as the authorities, for their hard work. We intend to continue developing this competitive, value-creating project for Normandy, which will provide renewable electricity to nearly one million French homes,” said Thierry Muller, Project Director for Centre Manche Energies.

Finalization of the initial surveys

In line with regulatory requirements, the application includes technical and environmental surveys, a preliminary design for the wind farm, and the planned installation program. The environmental impact assessment takes account of the findings of the aforementioned surveys, regular discussions with government departments, and the contributions gathered through the consultation process carried out with regional stakeholders.

The project’s next steps

The permitting process is now entering a new phase, starting with completion of the dossier followed by its examination by the government. At the same time, Centre Manche Energies will pursue consultation with local officials, environmental organizations, seafarers, and the public to ensure the project is well integrated into the region’s economy and community.

A major French electricity project

Located more than 40 km off the Normandy coast, this will be the largest renewables project ever developed in France. Once built, it will generate around 6 TWh per year and supply enough green electricity to power more than one million French homes.

The project represents an investment of €4.5 billion and will generate significant economic benefits for the local region, employing up to 2,500 people during the three-year construction phase. TotalEnergies also plans to make use of the local workforce, which has specialist expertise in the offshore wind sector.

The project will also benefit European industry, as TotalEnergies intends to focus sourcing on European suppliers, particularly for wind turbines and electric cables.
