The Spanish government blamed the national grid operator and private power generation companies for an energy blackout on April 28, which left Spain and Portugal without power for hours. The blackout affected businesses, schools, and transport, causing chaos. Minister Sara Aagesen reported that miscalculations by the grid operator and failures by private generators contributed to the outage. Prime Minister Pedro Sánchez indicated that private companies might be accountable, while opposition leader Alberto Núñez Feijóo criticized the government's energy policies.
