Overview

• Endesa and Iberdrola asked to push Almaraz’s planned 2027–28 closure back to 2030 under a revised nuclear timeline.
• Ministerial sources described the submission as a declaration of intent rather than a formal petition.
• Prime Minister Pedro Sánchez set three red lines for extensions including citizen safety, electricity supply security and no extra cost for consumers.
• Naturgy and EDP declined to sign the proposal despite their participation in the 2019 nuclear closure protocol.
• An EY study notes that Spain’s unique nuclear taxes add about €27.3 per MWh to operators’ costs and complicate extension plans.
