Ignorant minister?  Ignorant reporter?  ...or both.

 The report was written by a committee of experts. Fifty, I think.
       The committee studying the blackout is made up of representatives of the Ministry for Ecological Transition and the
       Demographic Challenge (MITECO), the Presidency of the Government, the Ministry of Defence and the Ministry of the
       Interior. Specifically, the Department of Homeland Security, the National Intelligence Centre, the General Staff and the
       National Centre for the Protection of Critical Infrastructure are involved.

         The blackout, which occurred on 28 April 2025, affected the Iberian Peninsula, including Spain, Portugal and Andorra, and
       extended as far south as France. The power outage caused disruptions to essential services such as hospitals, airports and
       telecommunications networks. The causes of the blackout are being investigated by this committee.

Until they publish a detailed explanation of how it was that a predictable surge of power from solar PV at high noon was able to bring down the *entire* Spanish grid it looks like a white wash to me.
Also exactly what order the cascade failure occurred in (and name and prosecute the companies that they claim did not follow the rules).
If that claim is true then they were culpable for the failure.
Comparable UK reports name all the players involved and exactly what happened at each site and when. See for example the report on our fairly spectacular summer failure in 2023 - this is a summary:

NESO seem to have conveniently deleted the original National Grid technical report from their site :(   Aha found it:

And that is what a proper investigation report ought to look like!
