Overview
- Red Eléctrica filed formal allegations seeking to close the sanction case, saying its actions followed the rules and that the CNMC’s charge lacks the precision needed to defend itself.
- The operator says it gave the regulator more than 50 reports at its request and claims those documents were not added to the case file, which it argues skews the record.
- The CNMC is investigating a suspected breach of article 64.25 of Spain’s Electricity Sector Law, which covers how the generation mix is scheduled when grid security is at stake, and it has proposed treating it as a very serious infraction.
- Red Eléctrica also alleges a conflict of interest because the CNMC writes key operating rules such as the voltage-control procedure 7.4, which REE asked to update in 2020 but was changed only two months after the April 2025 blackout, a revision the company says could have helped prevent the event.
- The REE case sits within more than 60 post-blackout sanction files, and major utilities including Iberdrola, Endesa, Naturgy and Repsol have criticized the probes for reaching back up to two years before the outage.
