Red Eléctrica warns that it will analyze the sanctioning file opened by the CNMC regarding the blackout
Red Eléctrica de España announces that it will analyze the sanctioning file opened by the CNMC (National Markets and Competition Commission) for the blackout on April 28, 2025, presenting allegations to defend its actions. He emphasizes that the procedure is in the initial phase and that no infringement has been proven.
The company insists that the indications indicated by the regulator do not mean that REE is responsible for the incident, nor that the attributed events are the direct cause of the blackout. They also remember that the CNMC itself has indicated that the origin of the electrical failure cannot be automatically linked to the actions of the system operator.
REE maintains that different technical reports, both internal and external, indicate that the blackout had a multifactorial origin. Among them, he cites the company’s own report, the analysis of the corresponding committee and the opinion of the European panel of experts, which rule out regulatory non-compliance on the part of the operator.
