A massive power surge in April caused a historic blackout in Spain and Portugal. Experts say it was Europe’s most severe outage in two decades.
Damian Cortinas, president of Entso-e, explained that this was the first known blackout caused by overvoltage. Overvoltage happens when there is too much electrical current in the grid.
“This is new territory,” Cortinas noted. He also stressed that Entso-e’s role was not to assign blame for the failure.
New Territory for Europe’s Power Grid
The outage left parts of both countries in darkness for almost a full day. As a result, transport networks halted, phone lines went down, and internet connections stopped.
Authorities described the incident as a reminder of how fragile modern energy systems can be. In addition, it showed the importance of stronger grid protection.
Experts believe the event will spark new safety measures. Therefore, European regulators may push for stricter standards in power networks.
While disruptive, the blackout also highlighted the need for cooperation across countries. For example, stronger cross-border connections could reduce the risk of future failures.
Spain and Portugal are now reviewing strategies to prevent another large-scale outage. Energy analysts expect changes in infrastructure planning and monitoring.
The incident stands as a warning for Europe. Power grids must adapt quickly to keep pace with rising energy demands and climate-related stress.
