In April, a massive blackout left 60 million people in Portugal and Spain without electricity, marking the largest blackout in modern history. The Iberian Peninsula is particularly vulnerable due to limited connections to the continental grid. Spain recovered fully in 16 hours with external support, while Portugal restored its grid independently in about 10 hours. Both countries are urging the EU for stronger interconnections to prevent future disruptions. A Spanish report attributes the blackout to systemic failures rather than external attacks. The importance of interconnections is emphasized, especially for countries like Portugal that rely heavily on Spain.
