It's been 20+ years since I worked in a state power control facility, it seems from your comment that you've never done such a thing; they're more complex than your comment suggests.

The preliminary report was exactly that, preliminary off the cuff listing of things that might cause issues with no definitive conclusion .. hence the need for longer consideration and a final report.

It's routine across the globe to bring power generation facilities on and off, and spin them up in anticipation of need - this incident is a failure of a control algorithm regardless of politics.
