EDF has lowered again its French nuclear output estimate from 300-330 TWh to 295-315 TWh. In January 2022, EDF already revised downward its nuclear output estimate from 330-360 TWh to 300-330 TWh for 2022. This revision was the result of the extension of the outage period for 5 of EDF's French nuclear reactors, including Civaux 1, Civaux 2, Chooz 1, Chooz 2 and Penly 1, due to defaults close to the welds on the pipes of the safety injection system (SIS) circuit.
EDF produced 361 TWh of nuclear power in France in 2021 (+7.5% compared to 2020, thanks to a higher availability of its nuclear fleet and high wholesale electricity prices). Nuclear power accounted for 66% of the total generation in France in 2020.
