For those that can follow spoken Spanish, there has just been a detailed explanation on Radio Cadena Ser. Aimar Bretos interviewed Jorge Morales on Hora 25:

 Hi Carlos,
 For those of us that can't follow spoken Spanish at all please can you precis what he said was the root cause of failure? Options seem to be:

No, that he didn't say. Not possible to say.

 1. France-Spain interconnect failure
2. Cyber attack
3. Human Error
4. Exceptionally "Rare" atmospheric phenomena
5. Flying pigs/unicorns [delete as appropriate]
6. Other

6, I guess. 2 is a possibility. 3 too, of course. 1 is not.
That the interconnection to Europe is too small, is a factor. We could not rely on Europe for stabilization. Another factor, in reverse, was not isolating into small sections inside of Spain, some of them might have survived.

 Reuters still hasn't picked up on it at all. Latest is here:
 https://www.reuters.com/world/europe/sanchez-pressed-explain-spains- blackout-grid-says-solar-not-blame-2025-04-30/
 I'm not sure that I believe them.
 I'd stand a bit more of a chance chance with a text based page.
Thanks.

Sure, I'm waiting for a good one, letting others decide on which is a good one.
