There is no evidence that a cyberattack was the cause of a major power outage on the Iberian Peninsula on April 28. This was stated by Spain's Energy Minister, Sara Aagesen Muñoz, according to the Reuters news agency at a press conference on Tuesday.
Here she reveals some of the results of a report that will be published later on Tuesday. The minister also says that signs of instability in the system had been found leading up to the outage. The outage paralyzed everything from traffic to telephone coverage.
On Tuesday, Aagesen Muñoz said that the chain reaction that led to the major outage was due to an inability to control the voltage in the power grid. Several power plants did not regulate the voltage in the way that the legislation otherwise requires.
- The system did not have sufficient dynamic capacity to control the voltage, says Aagesen.
Does not want to name specific power plants
She says that several power plants "should have controlled the voltage" and that they were also paid to do so. Legal processes are needed to determine whether anyone can be held responsible for the breakdown.
At the same time, the Minister of Energy does not want to name specific power plants. She also says that there are several reasons for the breakdown.
It is the worst breakdown that has ever hit Spain and Portugal, and the investigation into the causes has dragged on. Previously, Aagesen Muñoz said that private electricity companies were slow to share information about the major outage.
The outage lasted several hours, stranding thousands of people on trains and in elevators across the Iberian Peninsula.
