In its third full year of operation the Saint-Nazaire offshore wind farm produced approximately 1.6 TWh of electricity at a load factor of 37% against the 480 MW installed capacity, an improvement on both the 1.5 TWh recorded in 2023 and the 1.4 TWh recorded in 2024. The 2025 figure represents the highest annual output since commissioning and brought the project closer to its 1.7 TWh design-case annual yield. According to EDF power solutions' offshore wind asset-management director, the improvement was driven by two combined effects: a year in which the wind resource was approximately in line with forecast (versus a below-forecast 2024), and a maturity effect from three years of operating experience, including better-planned preventive and corrective maintenance windows, improved scheduling of low-wind maintenance days, and stronger overall pilotage of the asset. EDF, Enbridge and CPP Investments described the project as having reached its "vitesse de croisière" / operational cruising-speed regime. The fleet supporting the year's operation comprised the standard rotation of around 100 year-round personnel (rising to 150 in summer), with about 25-30 EDF power solutions employees, GE Vernova turbine maintenance teams, three Louis Dreyfus Armateurs CTVs based at La Turballe, and a temporary SOV charter (Olympic Notos) during 2025 for specific turbine campaigns.
