US EditionGranada substation power loss pinpointed as origin of massive blackout in Spain, Portugal
- On April 28, a sudden power failure at a Granada substation, quickly followed by outages in Badajoz and Seville, caused a widespread blackout that impacted both Portugal and Spain.
- Authorities attributed the outage to a 2.2-gigawatt generation loss caused by issues outside the main grid, with investigations considering excessive voltage and grid volatility as possible factors.
- Spanish Energy Minister Sara Aagesen ruled out cyberattacks, supply-demand imbalance, and insufficient grid capacity, and confirmed ongoing analysis of millions of data points from the affected areas.
- Critics linked the blackout partly to low grid inertia due to Spain's small nuclear and fossil fuel share, but Aagesen defended renewables for lowering costs and enhancing energy autonomy amid geopolitical challenges.
- The government continues investigations with openness to extending nuclear plant life conditional on safety and cost, while acknowledging establishing causes will take time without premature responsibility attribution.
