On February 26, 2025, a group of 32 companies from the Spanish nuclear industry, including Empresarios Agrupados-GHESA (EAG), Framatome, GDES, GE Vernova, IDOM, and Westinghouse, signed a manifesto advocating for the continued operation of Spain’s nuclear power plants beyond their scheduled closure. Spain currently operates seven nuclear reactors—Almaraz I and II, Ascó I and II, Cofrentes, Trillo, and Vandellós II—which provide approximately 20% of the nation’s electricity. According to a 2019 plan, these facilities are set to shut down in phases, with four reactors ceasing operations by 2030 and the remaining three by 2035.

The manifesto highlights the need to revisit the 2019 shutdown agreement, stating: "We urge the initiation of a dialogue and renegotiation of the 2019 agreement on the phased shutdown of nuclear power plants. This agreement was made under an industrial, geopolitical, social and economic context that is vastly different from today’s reality." The companies argue that closing these plants, starting with Almaraz in 2027, could undermine industrial competitiveness unless a practical alternative incorporating all low-CO2 energy sources is established.

The signatories propose updating the National Integrated Energy and Climate Plan to support nuclear energy’s role as a reliable, efficient, and low-emission resource. They emphasize that extending plant operations would maintain energy system stability, support the growth of renewable energy, and enhance Spain’s energy independence. The manifesto also addresses economic challenges, noting: "It is crucial to ensure the economic viability of nuclear power plants, with a special emphasis on the excessive tax burden imposed on the sector."

Spain’s nuclear facilities have undergone upgrades, enabling them to potentially operate for 60 or even 80 years, aligning with international practices. The industry supports nearly 20,000 skilled jobs across engineering, manufacturing, and service sectors. The document warns that early closures could harm local economies, stating: "The premature dismantling of these infrastructures would deal an irreparable economic and social blow to the regions where they operate." It further notes that such closures would raise environmental and economic costs, reduce technological capabilities, and affect employment in related fields.

On February 12, 2025, the Spanish Congress approved a proposal from the People’s Party to reconsider the nuclear phase-out, passing with 171 votes in favor, 164 against, and 14 abstentions. This development signals ongoing debate about the future of nuclear energy in Spain. The companies’ manifesto reinforces this discussion, advocating for a balanced approach to ensure energy security and economic stability while addressing climate goals.
