EDF increases its estimate of nuclear power generation in France for 2025. Initially estimated between 350-370 TWh, it is now estimated between 365-375 TWh1

The estimate of nuclear power generation in France for 2026 and 2027 remains unchanged at 350-370 TWh. 

This higher nuclear power generation estimate is based on improved management of outages thanks to the “START 20252” action plan implemented since 2019 aimed at improving the operational efficiency of the maintenance programme. It covers various areas: industrialisation, capitalisation, and standardisation of outages preparation methods, an optimisation of allocating resources and skills, including the setting up of pooled teams and more employee training in sensitive actions. At end-September, 18 outages out of 33 have been shorter than expected in 2025. 

Furthermore, the teams are committed to ensuring a production capacity of over 400 TWh per year.
