A massive power blackout affected Spain and Portugal, with only minor disruptions in southwestern France due to its swift disconnection from the Spanish grid. Experts believe the risk of a similar large-scale blackout in France is low, thanks to its robust electrical infrastructure and emergency measures. France provided emergency power to stabilize the Spanish grid and has backup systems in place for critical infrastructure. While the effectiveness of Europe's electricity network was highlighted, researchers caution that the exact cause of the Spanish blackout is still unknown, making it difficult to predict similar events in France.
