Électricité de France (EDF) has raised its nuclear production range for 2025, now estimated between 365 and 375 terawatt-hours (TWh), compared to the initial forecast of 350 to 370 TWh. This revision is based on the early operational outcomes of its industrial programme aimed at enhancing plant performance.

A programme launched to secure investments

This improvement directly results from the “START 2025” action plan, launched in 2019 by the group to industrialise and streamline maintenance cycles. The programme aims to strengthen outage preparation through standardised procedures, shared teams, optimised resource allocation, and targeted skills development. By the end of September, 18 out of 33 outages carried out in 2025 had been shorter than initially planned, increasing unit availability.

Stability expected in the medium term

For the years 2026 and 2027, EDF maintains its nuclear production forecast between 350 and 370 TWh. No adjustments are currently anticipated, though the group continues to deploy its industrial management tools across its entire fleet. These forecasts are part of a long-term strategy to secure supply levels while stabilising technical performance.

An annual target above 400 TWh

In parallel with its annual projections, EDF’s operational teams continue to target a production capacity above 400 TWh per year. This target serves as a benchmark for the group, supporting its investment ambitions while ensuring a stable base of domestic nuclear output.

The START 2025 plan stands as a key lever in this dynamic, combining industrial approach, strengthened training, and efficient management of technical outages.
