Spain Extends Almaraz Nuclear Plant License to 2030 Amid Energy Crisis 2026

Spain has decided to extend the operating license of the Almaraz nuclear plant until June 8, 2030, delaying its planned closure by about two and a half years. The move, approved by the Ministry for Ecological Transition and published in the Official State Gazette (BOE), comes in response to what the government calls an “exceptional and unforeseen international energy situation” marked by high volatility and elevated fossil fuel prices.

The extension was requested last autumn by Iberdrola, Endesa, and Naturgy, the utilities that own the plant. It marks a significant shift from the previous schedule, which had Almaraz’s two reactors shutting down in November 2027 and October 2028. That timeline was part of a 2019 agreement between the government and electric companies to phase out all nuclear power by 2035.

Why Spain Extended Almaraz’s License

The official justification centers on the war in the Middle East and its impact on global energy markets. According to the Ministry, led by Sara Aagesen, the conflict has created a scenario of “elevated volatility and high fossil fuel prices, the duration of which is currently impossible to predict.” Keeping Almaraz online helps shield Spain from sudden spikes in gas and oil costs.

Nuclear power provides a stable, low-carbon source of electricity that is not subject to the same price swings as fossil fuels. By extending Almaraz’s life, Spain gains additional breathing room to manage its energy transition without exposing consumers to excessive price shocks.

The 2035 Nuclear Phase-Out Plan Remains

Despite the extension, the government insists that the broader plan to close all Spanish nuclear plants by 2035 is still in place—at least for now. The Almaraz reprieve is framed as a temporary measure rather than a reversal of policy. However, energy analysts note that delaying the first closure could set a precedent for other plants.

The decision also reflects the realities of Spain’s electricity mix. Nuclear accounts for around 20% of the country’s power generation, and replacing that capacity with renewables and storage is not yet fully feasible without risking supply security.

What the Almaraz Extension Means for Energy Security

Almaraz, located in Cáceres, is one of Spain’s most important nuclear facilities. Its two reactors have a combined capacity of over 2,000 megawatts, enough to power millions of homes. Keeping them running helps maintain grid stability and reduces reliance on imported fossil fuels.

The extension also buys time for the development of renewable energy projects and energy storage infrastructure. Without Almaraz, Spain would need to ramp up gas-fired generation or imports to fill the gap, both of which could drive up electricity prices.

• Delayed closure: Almaraz will now operate until June 2030 instead of 2027-2028.
• Reason: Middle East war and volatile fossil fuel prices prompted the extension.
• Requested by: Iberdrola, Endesa, and Naturgy, the plant’s owners.
• 2035 phase-out: The overall plan to close all nuclear plants by 2035 remains unchanged.
• Energy mix: Nuclear provides about 20% of Spain’s electricity, supporting grid stability.

Political and Economic Reactions

The decision has drawn mixed reactions. Industry groups and some opposition politicians have welcomed the extension as a pragmatic move to protect consumers and ensure supply. Environmental organizations, however, criticize it as a setback for Spain’s climate goals and a distraction from investing in renewables.

Economically, the extension is expected to have a moderating effect on wholesale electricity prices, especially during periods of high gas costs. It also provides certainty for the plant’s workforce and the local economy in Cáceres, where Almaraz is a major employer.

What to Watch Next

Several key developments will determine whether the Almaraz extension remains an isolated case or becomes a trend. The government’s upcoming energy plan, due later this year, will clarify the future of other nuclear plants. Additionally, the evolution of the Middle East conflict and its impact on fossil fuel markets will influence any further adjustments.
