What caused it?
The Portuguese prime minister, Luís Montenegro, said that the issue originated in Spain. Portugal’s REN said a “rare atmospheric phenomenon” had caused a severe imbalance in temperatures that led to the widespread shutdowns.
REN said: “Due to extreme temperature variations in the interior of Spain, there were anomalous oscillations in the very high voltage lines (400 kV), a phenomenon known as ‘induced atmospheric vibration’. These oscillations caused synchronisation failures between the electrical systems, leading to successive disturbances across the interconnected European network.”

Every single major power outage on this list https://en.wikipedia.org/wiki/List_of_major_power_outages https://en.wikipedia.org/wiki/List_of_major_power_outages has taken between a day to a week to diagnose. You can read about the list of detailed theories if you click through to any of them, here's an example: https://en.wikipedia.org/wiki/2020_Sri_Lankan_blackouts https://en.wikipedia.org/wiki/2020_Sri_Lankan_blackouts Even your minor power outages take 30 minutes to an hour for your local power company to determine what failed.

A cold start from zero generation took 6 to 10 h. No casualties, hospitals and crtitical infrastructure kept working all day. Whatever the cause, this has been a great test of the emergency protocols.
