Estimated damage from Spain's power outage totals 1 billion euros
Power Outage in Iberian Peninsula: What Really Happened?
Let's shed some light on the power blackout that gripped Spain, Portugal, Andorra, and parts of southern France on April 28th, 2021. The situation remains unclear, with theories ranging from wildfires to cyberattacks flooding the news. But fear not, we've dug deep to separates facts from fiction.
The event caused significant disruptions, leaving millions without power and impacting various infrastructures. While Spain and Portugal have reported a full restoration of electricity networks, France experienced brief outages near the border. Hospitals, however, managed to keep the lights on, thanks to their backup generators.
The question of the hour: what caused this massive power failure? The Spanish Prime Minister, Pedro Sánchez, disclosed that the country lost an astounding 15 GW of power in mere five seconds, equivalent to 60% of national demand. This sudden power shortage has been a hot topic, with theories abounding. But, for now, all we have are clues—and some official statements.
Official reports suggest that the power disruptions were due to a "rare atmospheric phenomenon" in Portugal, causing "abnormal fluctuations" in high-voltage power lines. However, there's no clear indication if this was the sole cause. In fact, other reports point to an incident on a 400,000-volt power line owned by Red Eléctrica Española as the culprit, although investigations are ongoing to confirm this as the definitive cause.
The Portuguese Prime Minister, Luís Montenegro, assures that there are "no signs" that the power outage was due to a cyberattack. Nevertheless, the authorities are also looking into this possibility, as it would not be out of the ordinary for such an investigation in the wake of such a catastrophic event.
