Where can one find the report? Couldn't find anything on their website or elsewhere. I was only able to find the following media briefing via Reuters [0]:

> REE's System Operations Chief Eduardo Prieto told a news briefing the electricity system was hit by a dramatic power generation loss in southwestern Spain, that caused instability in the system that led to its disconnection from the French grid. He said it was quite possible that the affected generation was solar, but it was too early to say for sure.

This doesn't quite read like them blaming solar either. If anything, they're painting it as one of the victims of the failure.
