The Spanish government has extended the operating licence for the Almaraz in the province of Cáceres extended until 8 June 2030. The decision is based on a favourable vote with conditions from the Consejo de Seguridad Nuclear dated 16 July 2026. The Ministerio para la Transición Ecológica y el Reto Demográfico implemented the decision; the corresponding order was published in the Boletín Oficial del Estado . Both reactors at the plant can therefore continue operating beyond their previously scheduled closure dates.
Facts: The regulator’s conditions include updating safety documentation and clarifying requirements for staffing roles with safety-related duties between 2028 and 2030. The extension departs from the phased closure plan agreed in 2019, which scheduled the end of power generation at Almaraz I for 1 November 2027 and at Almaraz II for 31 October 2028. The operator is Centrales Nucleares Almaraz-Trillo (CNAT), in which Iberdrola, Endesa and Naturgy have stakes. The state authorities refer to ongoing safety reviews; the regulator and the ministry are responsible for enforcing the conditions.
Uncertainty in energy markets has increased since 2024/2025. Official and industry-related sources have pointed to rising electricity demand, fuel price volatility and the role of reliable generating capacity. Nuclear power made a significant contribution to Spain’s electricity generation in 2025, while renewables reached record levels but remain weather-dependent. Against this backdrop, the government justifies the extension on the grounds of security of supply and an orderly transition, without calling the expansion of renewables into question.
Implications and interests: For CNAT, the deadline of 2030 provides predictability for operations, upgrades and preparations for decommissioning. In Extremadura representatives of business and local authorities stress the importance of the plant for employment and economic value. From a regulatory perspective, ongoing oversight by the Consejo de Seguridad Nuclear is central; the ministry remains responsible for integrating the decision into energy policy.
Attributions and forecasts: Environmental organisations and some opposition parties criticise the departure from the closure timetable as a step backwards on climate policy. The government points to security of supply and price volatility. Whether other Spanish nuclear power stations will receive similar extensions remains an open question and depends on technical assessments, cost considerations and political decisions in the coming years.
