Nuclear energy satisfies 50.6% of Catalonia's electricity demand and 8.9% of Spain's. This data, on its own, already demonstrates the crucial importance of this energy which has an expiration date. Of the three reactors in Catalonia, the one at Ascó I is scheduled to close on October 1, 2030, Ascó II in 2032, and Vandellòs II in 2035. Proponents of this method for obtaining energy, which does not worsen global warming but does generate radioactive waste, maintain hope of securing an extension, just as happened with the Almaraz nuclear power plant, which was due to close next year, but which, thanks to a ministerial order from the Ministry for Ecological Transition published this August, will remain in operation until at least 2030.
