Overview

• The government inquiry found that a convergence of voltage control failures, including delayed programming and an abnormal oscillation at a Badajoz solar plant, triggered the April 28 power collapse.
• The outage left 55.7 million people across Spain and Portugal without electricity for 26 hours, marking one of Europe’s most severe grid failures in decades.
• Red Eléctrica Española and private energy firms have traded accusations over inadequate tension control measures and system programming prior to the blackout.
• The CNMC and potentially the courts are set to assess responsibility and determine financial liability for the incident.
• The government has pledged to reinforce grid stability through infrastructure upgrades designed to preserve renewable energy capacity.
