Overview

• A 15 GW power outage on April 28 disrupted life across the Iberian Peninsula, briefly affecting southern France, with full restoration achieved by April 30.
• Redeia, Spain's grid operator, has ruled out cyberattacks as the cause but continues investigating technical origins while emphasizing the stability of renewable energy systems.
• The blackout has intensified scrutiny of Spain's rapid renewable energy transition, with Redeia's February 2025 report warning of risks tied to smaller installations and loss of conventional capacity.
• Redeia’s president, Beatriz Corredor, has rejected claims linking the outage to renewable energy penetration, asserting that renewables operate stably with existing mechanisms.
• The incident has prompted broader discussions across Europe, including in France, about balancing renewable energy growth with grid stability and resilience.
