Share of nuclear energy in electricity production

In order to pursue the objective of diversifying the electricity mix in France, the Energy Transition Law for Green Growth (LTECV) adopted in August 2015 had set the objective of reducing the share of nuclear power in the electricity production to 50% by 2025. In November 2019, the Energy-Climate Law (LEC) noted the postponement of this objective to 2035 instead of 2025. It is specified in the Pluriannual Energy Programming (PPE) that this objective would imply, among other things, closing 14 nuclear reactors in France by 2035. In February and June 2020, the two reactors at the Fessenheim plant were closed. France currently has 56 nuclear reactors at 18 sites with a total installed capacity of 61.4 GW.

According to data from the Réseau de Transport d'Électricité (RTE) in France, nuclear generation will account for 69% of electricity production in France in 2021. This share is slightly above the share induced by a linear reduction between 2019 - the year in which the target was set - and 2035 - the year by which the target must be reached. Indeed, a linear reduction of the nuclear share in electricity production would imply a ratio of 68% for the year 2021 and 66.7% for 2022.
