In 2023, 13 EU countries with nuclear electricity production generated 619 601 gigawatt hours (GWh) of electricity, an increase of 1.7% compared with 2022, largely due to France completing maintenance of its nuclear reactors. Nuclear power plants from these 13 countries accounted for 22.8% of the total electricity production in the EU.
EU’s largest nuclear producer, France, generated 54.6% of the EU’s nuclear power (338 202 GWh). Spain followed with 58 873 GWh (9.2%), ahead of Sweden (48 470 GWh; 7.8%) and Finland (34 308 GWh; 5.5%).
Germany generated a total of 7 216 GWh in early 2023 before terminating nuclear production completely in April. This EU country was the second largest producer in the EU up until 2021.
