The blackout of the Iberian Peninsula on April 28, 2025.

E. Lobato

XXIV Power Systems Computation Conference - PSCC 2026, Limassol (Cyprus). 08-12 June 2026


Summary:

At 12:33 on 28th April 2025, a blackout occurred in the Iberian electricity system. Sixty million people lost the electricity supply. This is the first time in the history of the Spanish peninsular electricity system that a blackout has occurred. The most serious incidents in the peninsular system (July 1977, October 14, 1987, and August 24, 1994) never resulted in a blackout in the Iberian system. It is only comparable in continental Europe, in terms of severity, with the blackout of the Italian system on September 28, 2003.

 On April 30, the Spanish government established a committee to analyze the electricity crisis, chaired by the Third Vice President and Minister for Ecological Transition and Demographic Challenge. On June 17, the Council of Ministers approved the report drawn up by this Committee. On June 18, Red Eléctrica, the Spanish TSO, presented its report on the events. On May 9, ENTSO-e established a panel of experts to investigate the incident. ENTSO-e presented its factual report on October 3. [...]
