US EditionSpain’s Blackout Story Is Disintegrating
- In late April 2025, a widespread power outage affected almost the entire Iberian Peninsula, leading to major disruptions in critical services and infrastructure throughout Spain and Portugal.
- The blackout resulted from a rapid cascading grid failure triggered by frequency dropping below 50 hertz amid insufficient grid inertia and backup capacity.
- Spain’s increased reliance on intermittent solar and wind power, combined with aging nuclear reactors averaging 47 years old, strained grid stability.
- Following the outage, Spain boosted combined-cycle gas turbine output by 37%, with about 2 gigawatts of additional gas-fired capacity added daily to stabilize the grid.
- The event highlighted the need for improved grid inertia and backup technologies to handle renewables’ variability, implying strategic reconsideration of Spain’s energy mix.
