The Court of Spain began the investigation of a large -scale blackout. One of the versions - cyber attack

The Supreme Court of Spain announced the start of the investigation after a large -scale power outage in the country on April 28. The purpose of the investigation is to establish whether Blackout was the result of cyber attacks. This is written by Bloomberg.

The judge demanded that the National Cybersecurity Agency and the operator of the mains submit reports on the causes of the failure. The same request was sent to the National Police. The judge noted that the causes of Blackout are still unknown, but “cyber terrorism is one of the versions under consideration,” therefore it is necessary to conduct an investigation.

On Monday, April 28, on a significant part of the Pyrenee Peninsula (in Portugal, part of Spain) and France, power supply disappeared. The Spanish nuclear power plants stopped during disconnects, the work of the entire railway infrastructure was paralyzed. There are no final data on the reasons for the Blackaut.

According to Portugal Prime Minister Luis Montenegra, there are no signs that the shutdown was caused by cyber attacks, but it is too early to exclude any scenario.

The Spanish operator of the REE electric networks on Tuesday excluded the version of the cyber attack as the cause of Blackaut. According to REE, two power losses in the south-west of the country were recorded, probably at the solar power plants, which caused the instability of the energy system and led to a breakdown of the connection with France.

The Portuguese operator of the Ren network said that Blackout is caused by a malfunction in the Spanish power grid associated with a “rare atmospheric phenomenon”. It argues that due to extreme temperature fluctuations in Spain, “abnormal fluctuations” on very high voltage lines were recorded. The message also says that the full normalization of the network can last up to a week, Sky News reported .

According to the RBC investment bank, economic damage from shutdown can be from 2.25 to 4.5 billion euros. In the report, the bank accused the Spanish authorities of insufficient attentiveness to infrastructure in conditions of dependence on solar energy and insufficient batteries.
