In 2021, EDF produced 42 TWh of hydropower in France in 2021 (-6.5%) and 360.7 TWh of nuclear power in France (+7.5% compared to 2020, thanks to a higher availability of its nuclear fleet and high wholesale electricity prices), as well as 41.7 TWh of nuclear power in the United Kingdom (-8.7%). The company owns and operates 56 nuclear reactors on 18 sites in France with a total capacity of 61.4 GW and 8 nuclear units in the United Kingdom with a total capacity of 8.1 GW (end-2020). Dungeness B (1 040 MW) in the United Kingdom was shut down in June 2021 and Hunterston B (two gas-cooled reactors, 960 MW) in January 2022.
In July 2021, EDF revised upward its nuclear power generation forecast for 2021 in France, from 330-360 TWh to around 345-365 TWh (+3% to 6%). The output estimate for 2022 remained unchanged at 330-360 TWh. Nuclear accounted for 66% of France's power mix in 2020, and 16% of the United Kingdom's total generation.
