Spain's power outage mystery persists: What caused the massive blackout remains undisclosed
The root cause of the blackout in Spain remains undetermined
Nearly a fortnight since the catastrophic power outage engulfed the Iberian Peninsula, the root cause still remains shrouded in mystery. Spanish Prime Minister, Pedro Sánchez, urged patience during a parliamentary session, asserting that the intricate examination of around 756 million data points is a time-consuming process. He reiterated that there's no vestige indicating that the integration of renewable energy sources into the grid was culpable.
Sánchez echoed what the Minister of Environment had already stated on Monday: The power outage commenced with three distinct precursors in rapid succession. According to preliminary technical data, an anomaly was initially detected in southern Spain, followed closely by two more anomalies in the southwest of the country. The grid managed to withstand the first two anomalies, but succumbed to the third, spreading the chaos across the entire power system of the peninsula.
Despite this, Sánchez insists that there's no evidence to support the notion that an influx of solar energy triggered the devastating outage. Nor was the absence of nuclear power plants the catalyst – a suggestion made by the opposition, striving to prolong their operations.
The power outage on April 28 affected not only Spain and Portugal but also caused turmoil in southwestern France and Morocco. It was one of the largest power outages ever recorded in Europe.
Meanwhile, Spain's National Cybersecurity Institute initially delved into the possibility of a cyberattack as the root cause, but Red Eléctrica de España (REE), the Spanish electricity system operator, swiftly refuted this theory and narrowed their focus to investigating the disconnection event in the southwest of Spain that instigated the blackout.
A judicial inquiry led by Audiencia Nacional judge José Luis Calama is underway to corroborate if the blackout was a result of sabotage or a malicious act aimed at critical infrastructure. A joint expert panel, comprising ENTSO-E (the European Network of Transmission System Operators for Electricity), regulatory authorities, and Transmission System Operators (TSOs) from various regions, has been established. This panel is meticulously examining data to reconstruct the blackout event, identify root causes, and formulate preventive measures to quell future calamities. The investigation is expected to conclude in a few weeks, followed by a publication of comprehensive findings and recommendations to the European Commission and member states.
