Spain operable reactors, share of generation, CO2 mitigation

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 was removed, but at the end of 2023 the government confirmed that it would phase out nuclear power between 2027 and 2035.

However, in February 2025 the Spanish Congress approved a proposal, presented by the People’s Party, to reverse the phase-out policy. Later that month 32 companies involved in the Spanish nuclear industry, including Empresarios Agrupados-GHESA (EAG), Framatome, GDES, GE Vernova, IDOM and Westinghouse, signed a manifesto calling for the longterm operation of the country’s plants.
