Provence Grand Large the Mediterranean’s First Floating Offshore Wind Farm

France has officially announced the full commissioning of Provence Grand Large Offshore Wind Farm (PGL) — the first floating offshore wind farm in both France and the Mediterranean basin. Located 17 km off the coast of Port-Saint-Louis-du-Rhône in the Gulf of Fos (Bouches-du-Rhône), this pioneering project marks a major technological and environmental milestone.

With a capacity of 25 MW, the wind farm will generate clean energy equivalent to the annual electricity needs of 45,000 people, helping accelerate France’s transition to renewable energy sources.

A Technological First: Floating Wind Innovation

Provence Grand Large Offshore Wind Farm is a pilot project that introduces cutting-edge floating wind technology to the region. It consists of three Siemens Gamesa 8.4 MW wind turbines, each installed on tension leg floating platforms, a first-of-its-kind adaptation of deep-sea oil platform stabilization technology for wind power.

The innovative platform design was developed by SBM Offshore and IFP Energies Nouvelles (IFPEN). These floating foundations are tethered to the seabed with high-tension mooring lines, allowing them to operate efficiently in deep waters of around 100 meters.

Grid Connection with Dynamic Cables

Electricity generated from the turbines is transported via dynamic cables designed by Prysmian, capable of flexibly adapting to the motion of the floating platforms. These cables connect to subsea infrastructure, which then links to a land-based station operated by RTE, ensuring stable energy transmission to the grid.
