Overview

• The blackout, which began at 12:30 PM local time, affected Spain, Portugal, Andorra, and parts of France connected to Spain's grid.
• Red Eléctrica Española (REE) attributes the outage to an exceptional oscillation in power flows, disconnecting the peninsula from Europe's grid.
• National and cybersecurity agencies are investigating possible causes, including cyberattacks, sabotage, or large-scale technical failures.
• Critical facilities like hospitals have maintained operations using backup generators, while transport and communication systems face widespread disruption.
• Power restoration has started in northern and southern regions, but significant areas remain without electricity as phased re-energization continues.
