Electricity bill from Spain last year, now explained by experts: "Perfect storm" of factors

A mega power outage affected Spain and Portugal on April 28, 2025, causing chaos and major dysfunctions. A group of 49 experts concluded that the incident did not have a "single cause," but was the result of a "perfect storm" of multiple factors. Damian Cortinas, the president of ENTSO-E, stated that this was the worst power outage in the last two decades in Europe. The report highlighted the ineffectiveness of voltage control in the Spanish electrical system, which led to fluctuations and oscillations that caused widespread disconnections, especially in renewable energy-based plants. The incident paralyzed the entire peninsula, affecting electricity, the internet, mobile phone networks, and banking terminals, leaving the population in chaos.
