Analysis based on 9 articles · First reported Aug 14, 2026 · Last updated Aug 14, 2026
The extension provides near-term certainty for electricity supply in Spain, supporting grid stability and potentially moderating wholesale power prices. It benefits the plant's owners (Iberdrola, Endesa, Naturgy) by extending revenue-generating operations, while the broader nuclear phase-out by 2035 remains unchanged, limiting long-term market impact.
On August 14, 2026, the Spanish government, through the Spain — Ministry for Ecological Transition and Demographic Challenge, authorized the extension of the operating life of the Almaraz Nuclear Power Plant until June 8, 2030. This postpones the shutdown of its two reactors, originally scheduled for November 2027 and October 2028, by up to three years. The decision follows a request submitted in October 2025 by the plant's owners, Iberdrola, Endesa, and Naturgy, and a positive opinion from the Spain — Nuclear Safety Council issued on July 16, 2026. The government cited the tense international energy context, including the impact of the Iran war on fossil fuel prices and supplies, and the need to guarantee security of supply. The extension does not alter Spain's overall plan to phase out nuclear power by 2035. The decision was welcomed by local civic platforms and politicians in Spain — Extremadura, while the European Union — European Parliament had previously called on Spain to reconsider its closure schedule. The plant provides around 4,000 jobs and generates about 7% of Spain's electricity.
