Final analysis of 2025 Iberian blackout: Policies left Spain at risk

Spain's energy policies left its grid dangerously vulnerable to a single cascade failure, according to the final analysis of the 2025 Iberian blackout. The report found that renewable generation dropped to 12% of total capacity during a calm, cloudy week, forcing gas imports to spike 300% above baseline. The comparison is stark: while #4 discusses consumer inconvenience, this analysis warns that political choices created a system where one substation failure could collapse the entire grid.
