Spain grappled with the aftermath of its largest blackout in history, which cut 60% of electricity within five seconds the previous day. Morning brought cautious optimism as Red Eléctrica announced restoration of 99%, then 100% of electrical service, though transportation systems remained partially disrupted.
By midday, Prime Minister Sánchez held a press conference, promising to identify what happened "in those five seconds" and pledging accountability. Red Eléctrica officially ruled out a cyberattack, focusing instead on technical failures possibly involving solar plant disconnections.
The afternoon saw tensions rise as the European Commission demanded a report within three months and Portugal requested an audit. Sánchez summoned energy company executives to Moncloa for an emergency meeting, shifting blame toward private operators. By evening, Iberdrola pushed back, stating their plants followed Red Eléctrica's instructions, while fears of another blackout reduced mobility in major cities.
