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.
