That being said, I was apparently also under the impression of outdated or just plain wrong information.
While the report I listed mentions the sudden loss of decentralized generation as starting point of the blackout, and also specifically mentions small-scale rooftop PV, it says that the cause for that sudden synchronized drop-off is actually unknown.
You can't get an "informed opinion" by reading crap like that report.
The Spanish systems have systematic design failures for stability and electricity market design. Working out the political failures that led to the design failures is much harder.
Only those working closely in that profession have any knowledge of the underlying causes.
Most everyone else (including this comment) is different levels of ignorance and cluelessness.
Edit E.g. Crap quote from the report "but no significant oscillations with
amplitudes above 20 mHz". The rest of it is about that level from what I could tell.

This report is literally from the ENTSO-E which is the main regulatory body for the grid in Europe.
> Crap quote from the report "but no significant oscillations with amplitudes above 20 mHz".
What is the "crap" about that?
An amplitude can still be measured in Hz, if you are looking at oscillating frequency deviations, if that is what you mean.
