Slight increase in nuclear power production in 2023

Eurostat, 25.2.2025

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.
