The question of whether an electrical interruption like the one experienced a year ago in Sabadell could recur has been analyzed. Following that episode, various improvements have been implemented to minimize the risk. The original incident was caused by a severe alteration of the voltage in the network, specifically an overvoltage generated by a significant increase in photovoltaic energy. This situation led to the automatic disconnection of system components as a protection mechanism.
According to a researcher from the CITCEA-UPC group, the dynamic control mechanisms did not react quickly enough to contain the incident, allowing the problem to propagate in a chain reaction. From Endesa, it has been noted that oscillations reached an uncontrollable point, even though previous anomalies had already been detected. The outage affected the network, but not the infrastructure, facilitating a rapid recovery in approximately 12 hours.
“"It is very unlikely that a similar episode will occur again, but it cannot be completely ruled out in any case."
Both parties agree that, although a repeat is unlikely, it cannot be completely ruled out. However, there is a certain sense of calm thanks to new measures that have made the system more resilient. The network, which was previously unstable, has been gradually stabilized through an

In addition to the reinforced operation, an increase in energy storage capacity is planned to provide reserves in case of new incidents, a situation considered
“"All in all, therefore, it seems almost impossible for it to happen again."
