Spain is now emerging from an unprecedented national blackout that caused chaos and disruption across the country for almost a full day. On Monday, the electricity grid faltered due to two simultaneous connection failures in the southwest, which were compounded by a loss of connection to the French network, leading to a drastic loss of 15 gigawatts of power at 12:33 PM. By 11:15 AM on Tuesday, the grid operator announced a return to normal operations after extensive efforts to restore power.

The initial response involved prioritizing hydroelectric and gas plants, with careful measures in place to avoid overloading the system and triggering another outage. Spain's renewable energy mix, heavily reliant on solar power, has come under scrutiny as public officials blamed the saturation of solar generation for the blackout. At the time of the incident, 60.64% of the country's power came from solar sources.

Neighboring countries stepped in to assist; Morocco transferred 900 MW and France supplied over 700 MW to Spanish regions. By the evening of Monday, electricity had been restored to approximately 35% of demand, with significant progress made overnight. Ultimately, more than 99% of power was restored by Tuesday morning.

The economic impact of the blackout is substantial, with estimates predicting a €1.6 billion loss. Political leaders are now pointing fingers at the government for a perceived slow response, contributing to rising tensions amidst the crisis.

Despite the disruption, Spaniards demonstrated resilience and solidarity during the blackout, with hospitals maintaining operations thanks to backup generators. Local communities helped stranded travelers, showcasing the strength of solidarity in challenging situations. Spanish Prime Minister Pedro Sánchez has vowed to learn lessons from the event to mitigate future crises, while energy experts caution about the risks tied to the country's over-reliance on renewable energy sources.
