On Thursday, José Bogas, CEO of Endesa, and Mario Ruiz Tagle, CEO of Iberdrola España, appeared before a Senate committee investigating a significant blackout that occurred in Spain. Both executives strongly criticized the management of Red Eléctrica, asserting that their companies had issued multiple warnings about anomalies leading up to the incident. Tagle emphasized that the root cause was a single programming error that happened on April 28, highlighting the lack of timely response from Red Eléctrica despite repeated alerts from his company.

Bogas further elaborated on the communication challenges faced, indicating that Endesa's teams repeatedly questioned Red Eléctrica's technicians when they detected critical fluctuations in the grid, emphasizing that these inquiries were documented. He concluded that the state operator did not respond with the urgency and efficiency that was needed in light of the critical signals they were receiving, indicating a severe failure in readiness and management.

This exchange in the Senate highlights not only the technical failures that led to the blackout but also raises broader questions about the accountability of state-operated entities in Spain. The contrasting claims of responsibility between Red Eléctrica and private companies like Iberdrola and Endesa indicate ongoing tensions in the energy sector, which may influence future regulatory and operational strategies as the country seeks to enhance its infrastructural resilience.
