Spain - World Nuclear Performance Report

Spain has seven operable nuclear reactors at five sites across the country, all of which started up in the 1980s. With a combined capacity of 7123 MWe, the units generate over 20% of the country’s electricity.

Until 2011 it was planned that operation of Spain’s reactors would end in the 2020s as operating lifetimes would be limited to 40 years. That restriction has since been removed; however, at the end of 2023 the new
government confirmed that it would phase out nuclear power between 2027 and 2035. In July 2023 dismantling of the Santa María de Garoña nuclear power plant began following the transfer of ownership from Nuclenor to decommissioning and waste management firm Enresa. Decommissioning is expected to take about 10 years.
