Mega Blackout in Europe Today: Causes and Affected Countries

This Monday, April 28, a mega blackout in Europe was recorded, which left millions of citizens without electricity in Spain, Portugal, France, Italy, and Germany. Likewise, the effects were immediate, altering everything from public transportation to the operation of key infrastructures.

Specifically, the outage began around 12:30 p.m. (Spanish local time), just as the Spanish Electricity Network (REE) reported a consumption of 25,184 megawatts. Minutes later, the system plummeted abruptly to 12,425 megawatts, demonstrating a collapse in the electricity service.

So far, official information moves between uncertainty and hypotheses. Eduardo Prieto, director of services for the operation of Red Eléctrica, reported that the system experienced “oscillations in power flows,” which caused the collapse of the network. In addition, at a press conference, Prieto anticipated that the total restoration of the service could take between six and ten hours.

For his part, the president of the Junta de Andalucía, Juan Manuel Moreno, suggested a possible hypothesis of a cyberattack. According to preliminary data from the autonomous cybersecurity center, “everything indicates that a blackout of this magnitude can only be due to a computer attack”. However, there is still no official communication from the Spanish Government confirming this version.

Likewise, what is known is that Red Eléctrica is working on the restoration of the service. Through its account on X (formerly Twitter), the company detailed that the outage was caused by a “zero” in the electrical system, and that recovery is progressive as generation groups are reincorporated.

On the other hand, the blackout has had immediate and far-reaching consequences:

Public transport:

The Madrid Metro and the Cercanías network were paralyzed.
In Barcelona, at least 23 evacuations in Metro stations were necessary.
Airports such as Madrid-Barajas and Lisbon experienced reduced air traffic, according to controller reports.

Critical infrastructures:

150 incidents were recorded in elevators in Madrid, reported Mayor José Luis Martínez-Almeida.
Various workplaces and factories suspended operations due to the lack of energy.

Financial markets:

The Spanish Stock Exchange (BME) and the financial market infrastructures operated without interruptions.
However, some financial institutions reported connectivity problems, partially affecting customer service.

Despite the widespread collapse, authorities assured that essential services such as hospitals and emergency centers have backup generators that have prevented major crisis situations.

Progressive Recovery of the Mega Blackout in Europe3557

The recovery of service has already begun in several areas of northern and southern Spain. According to Red Eléctrica, the reactivation process follows a rigorous protocol that involves:

Gradual reincorporation of generation groups.
Stabilization of voltage in local networks.
Constant monitoring to avoid new outages or overloads.

Prieto insisted that, although some regions already show signs of normalization, the entire process could extend into the night. Meanwhile, the public is recommended to:
