Spain’s extension of the Almaraz nuclear plant to 2030 shifts the closure decision to the next government, breaking the PSOE‑Sumar pact and pleasing regional stakeholders
Executive summary: The Spanish government approved an extension of the Almaraz nuclear plant’s operation to June 2030, transferring the final closure decision to a future administration. The extension affects Spain’s electricity supply, wholesale power prices and the fulfillment of the PSOE‑Sumar coalition’s nuclear phase‑out commitment, creating political and regulatory uncertainty.
Who is involved: Spanish Government (PSOE‑led), Sumar party, regional parties and municipalities, electricity utilities (e.g., Endesa, Iberdrola), and the nuclear safety regulator (CSN).
Likely next: The next government, likely determined after the 2027 general election, will decide on the eventual closure; possible legal challenges and adjustments to energy auctions and state‑aid assessments may follow.
The Spanish government has granted a further operating licence for the Almaraz nuclear complex until June 2030, effectively deferring the plant’s shutdown to a future administration. The move contradicts the coalition agreement between PSOE and Sumar, which had envisioned an earlier phase‑out, while receiving support from regional parties, local municipalities and electricity utilities that value the continued capacity. The decision introduces regulatory and market uncertainty as Spain’s energy mix and upcoming capacity auctions now hinge on the political outcome of the next electoral cycle.
