- Aagesen noted that the system "lacked sufficient voltage control capacity" on the day of the blackout.
- Analysts from Spain's national security agencies found no evidence of cyber-sabotage related to the incident.

This is the response of the company to the document prepared by the Ministry for the Ecological Transition, which gives the good conclusions transmitted by the Elec…
How did the power failure on the Iberian Peninsula come about? An investigation report makes it clear that the so-called reactive power played the decisive role. However, the question of guilt is still open.
The system was also not adequate, which was not helped by the sudden, abnormal voltage fluctuations.
The government has presented this Tuesday the report on the causes of the big blackout that left the entire Iberian Peninsula without electricity on April 28.
