Spain's Power Outage Mystery Persists Ten Days On
Unresolved reasons behind Spain's recent blackout remain undisclosed
Seven days after the massive power outage that engulfed the Iberian Peninsula, the cause of the chaos remains elusive. Spanish Prime Minister Pedro Sánchez appealed for patience during a parliamentary session, stressing that meticulous analysis of over 756 million data points is required. As of now, there seems to be no evidence supporting the suspicion that wind and solar power feed-in to the grid was the culprit.
Sánchez echoed Minister Teresa Ribera's statements from Monday: The fundamental blackout started with an unusual sequence of three distinct events occurring swiftly. According to preliminary technical data, a disturbance was first detected in southern Spain; seconds later, two more disturbances appeared in southwest Spain. Although the system managed to weather the first two incidents, it failed to endure the third. This disturbance rapidly spread across the power system of the peninsula.
Despite public speculation, there is no concrete evidence suggesting an excess of solar power was the cause. Similarly, the lack of nuclear power plants doesn't appear to be the reason - a claim raised by the opposition who are advocating for extending their operational lives.
The power outage, which occurred on April 28, 2025, brought widespread disruption, causing severe traffic congestion, telecommunications failures, and temporary blacksouts in Southwest France and Morocco. This catastrophic event marked one of the largest power outages in European history.

- Spanish Prime Minister Pedro Sánchez has appealed for the implementation of a community policy to address the vulnerabilities exposed by the power outage, particularly focusing on improving the resilience of the grid.
- As part of the community policy, the government is planning to invest in vocational training programs for technicians and engineers to enhance their skills in managing the power system and preventing future blackouts.
- In addition to the vocational training, there are ongoing discussions about the role of new technologies, such as advancements in the energy sector and digital platforms like WhatsApp, in helping to predict and manage power outages more effectively.
- According to the initial analysis of the power outage's financial impact, the incident has caused estimated losses of over €1 billion across various industries, including industry, telecommunications, and finance.
