The CNMC opens sanctioning proceedings following the power outage

BarcelonaA few days before the first anniversary of the electrical blackout on April 28, new details of its possible causes continue to emerge. This Friday, the National Commission for Markets and Competition (CNMC) explained that it has initiated several sanctioning proceedings to determine the circumstances of the blackout. Thus, the regulatory body assures that, as a result of the investigations, "various indications of non-compliance" have been detected, some of them maintained for "prolonged periods of time," which could constitute administrative infractions.

However, as indicated by the CNMC, "the facts subject to these proceedings do not, in themselves, imply the attribution of the origin or cause of the blackout to the affected companies, given that the incident responded to a multifactorial origin." A few weeks ago, a study by the European Network of Transmission System Operators also concluded that the disconnection was due to "multiple factors" that are "interconnected with each other," such as "voltage oscillations," "cascade generator disconnections," and "overvoltages."
