Regulatory Lessons from the Iberian Blackout examines the April 2025 power outage in Spain and Portugal, one of the most significant electricity system failures in a high-renewable-energy environment. Drawing on the findings presented by Luca Lo Schiavo at the ERRA Chairmen Meeting (October 13, 2025 in Ankara, Türkiye), the article explores how outdated regulatory frameworks, delayed rule updates, and inadequate voltage control mechanisms contributed to the blackout despite sufficient generation capacity. The publication highlights key lessons for regulators on accelerating regulatory adaptation, strengthening system resilience, enabling market-based ancillary services, and ensuring that electricity sector rules evolve in step with the rapid growth of renewable energy sources.
