Overview

• The IIT report by professors Luis Rouco, Enrique Lobato and Francisco Echevarren identifies the absence of synchronous generation in southern Spain as the fundamental cause of the April 28 outage.
• ENTSO-E is expected to publish its own conclusions on the incident this Friday, providing an independent assessment of the event.
• The study says maneuvers carried out by Red Eléctrica were not able to operate when network disturbances occurred.
• Red Eléctrica has operated in a reinforced mode since May, adding gas and nuclear output to stabilize the system and reduce the risk of another blackout.
• Eurostat data show Spain’s electricity from renewables fell from 65% in April to 54% in June following the incident.
