As both Spain and Portugal encounter challenges in resuming routine operations, the primary concerns revolve around what transpired and how to avert similar extensive electricity blackouts.
Gradual Restoration of Power
The Iberian Peninsula grapples with restoration of power generation
Operation at regular capacity was not reinstated until 11:15 (09:15 GMT) on Tuesday, nearly 23 hours after the electrical network malfunctioned. Train services have resumed, although some lines remain idle, and the majority of households have reverted their power.
What Caused the Blackout and the Delays?
For a significant portion of Monday, Spain plunged into disorder. The situation is attributed to two simultaneous connection failures in southwestern Spain and a temporary disconnect from the French grid.
Prime Minister Pedro Sánchez reported a sudden loss of 15 gigawatts of electrical generation at 12:33 Monday, resulting in approximately 60% of Spain’s power production ceasing.
Solutions and Regional Impacts
Eduardo Prieto, the operations director of the grid Red Eléctrica, stated that the systems were stable until a blackout struck southwestern Spain and temporarily disrupted the French network interconnection.
The Canary Islands, Balearics, and the North African coastal cities of Ceuta and Melilla escaped the outage. Many public figures criticize the dependence on renewable energy, suggesting it may have overwhelmed the system. Minutes before the outage, Spain’s power mix comprised:
- 60.64% Solar photovoltaic generation
- 12% Wind power
- 11.6% Nuclear energy
Key Strategies for Restoration
Despite Spain’s diverse and advanced energy systems, restoring power after the collapse necessitated significant effort. The grid operator Red Eléctrica emphasized the importance of reactivating northern and southern power regions to gradually stabilize the transmission grid.
The goal was to avoid overwhelming the system by restoring everything simultaneously, which could have triggered another massive blackout. A phased approach, known as a “black start,” proved successful. Initial efforts focused on hydroelectric plants, particularly pumped-storage facilities that could rapidly generate power. Combined-cycle gas plants were also instrumental in revitalizing the grid.
Regional and International Support
The restoration efforts were further bolstered by neighboring countries:
- Morocco: provided 900MW through high-voltage lines from Fardioua to Tarifa.
- France: gradually increased electricity supply via lines to Catalonia and the Basque country, providing up to 2,000MW.
Power was ultimately restored to substations across Spain. By 19:20 on Monday, more than 20% of demand had been met through Spain’s own generation and French imports. Endesa, an electricity provider, had re-established service to nearly 3.5 million customers by 19:15, prioritizing hospitals and other critical infrastructure.
The Aftermath and Recovery Efforts
The economic repercussions of the power failure are becoming apparent, with initial estimates suggesting a €1.6 billion loss.
Economic and Political Ramifications
Criticism and political debates have emerged, with conservative leaders blaming the government for its response. Despite the hardships, Spaniards have been commended for their resilience and solidarity. Hospitals maintained operation using backup generators, and police forces managed to evacuate thousands of stranded passengers. Local communities and authorities provided critical assistance during the crisis.
Future Prevention and Lessons Learned
Spain aims to prevent similar crises in the future. However, the country’s energy infrastructure faces challenges due to the increasing integration of renewable energy sources and the closure of nuclear plants. The grid operator had previously highlighted risks associated with excessive renewable energy integration. Pedro Sánchez is committed to learning from this crisis to ensure better preparedness in the future.
