EDF estimates higher nuclear power generation in France for 2025

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

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

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 400TWh per year.
