In 2024, 12 EU countries with nuclear electricity production generated 649 524 gigawatt hours (GWh) of electricity, an increase of 4.8% compared with 2023. This was the second consecutive year with a rise since the 2022 decrease (609 255 GWh). Nuclear power plants accounted for 23.3% of the total electricity production in the EU. 

The EU’s largest nuclear producer, France, generated 58.6% of the EU’s nuclear power (380 451 GWh). Spain followed with 54 510 GWh (8.4%), ahead of Sweden (50 665 GWh; 7.8%) and Finland (32 599 GWh; 5.0%). 

Compared with 2023, nuclear electricity production increased the most in France (+12.5%), followed by Sweden (4.5%) and Slovenia (+4.2%). The other producers of nuclear electricity registered an average decrease of 4%, varying between -0.6% in Slovakia and -10.3% in the Netherlands.
