Overview
- Spain’s Ecology Minister Sara Aagesen told Parliament that claims of grid experimentation are “totally false,” denying any government-led tests before the April 28 blackout.
- Beatriz Corredor, president of Red Eléctrica Española, dismissed theories of excessive renewables, cyberattack, short-circuit or overload while identifying voltage control irregularities in conventional power plants.
- The Association of Spanish Electricity Companies reported no defects in member installations and urged REE to provide full data to all stakeholders.
- Spanish authorities logged two strong electrical oscillations 30 minutes before the outage, followed by three rapid substation failures in Granada, Badajoz and Seville.
- Investigators say the blackout’s root cause remains unknown as they focus on voltage anomalies and transparency in the ongoing inquiry.
