Spanish Blackout Lessons One Year On: Analyst Reaction | Switched On

It’s been nearly a year since Spain’s catastrophic blackout and key questions remain. Post-mortem reports point to a complex chain reaction in the grid, with no single trigger and gaps in coordination between operators, regulators and generators. The findings expose deeper challenges: inconsistent voltage rules, rising operational complexity and a system evolving faster than its controls. Renewables were initially blamed for helping trigger the crisis, but they are fundamental to the Iberian grid and must be part of the solution. So what has Spain really learned, and how prepared are other power systems for the next shock? On today’s show, Kamala Schelling is joined by Eva Gonzalez Isla, a senior associate from BNEF’s grids team, to discuss her note: “Spain’s Blackout Reports Expose Voltage Safety Risks.”
