Conclusions
There were natural anomalies that could cause problems in the networks themselves.
The blackout was prepared at such a time that it could be easily "explained" as a system failure.
This suggests that some forces knew that a window of vulnerability would appear.
Looks like whatever the explanation for the outage ends up being, a large part of this story is going to be about over reliance on renewables. Grids become vulnerable due to the fine margins and restarting becomes more difficult.
If this was the cause, and since it was mostly Spain (Portugal being a knock-on effect), maybe it has something to do with the Spanish govts. attitude to both Israel and Ukraine.
So a combination? They did know about the natural window of vulnerability, they exploited it by some kind of Haarp related technologie. It was amplified by the fragility of the grid due to reliance on renewables and so... boom. Punished.
i.e. natural phenomenon exploited to generate fear and so... saoul energy release?
