They say the typical. Pull out cash get some extra food and stuff. I’ve never had a warning from them before and would consider them reliable. When Covid crumbles the distraction is close.

Not sure about that - I would need to grab the details but the power grids although intertwine. The systems or source energy are on isolated grids. Their systems are not certified for cloud, or weren’t a few years back. I know PSE in W.Wa has backup infrastructure in E.Wa via portable units. They’re fully enclosed, isolated and independently powered - designed specifically for ICS. Chelan County PUD infra is completely segregated, obviously they’re self sustaining.
The chance of a nationwide power outage is not likely. There would need to be a massive coordinated attempt, a regional EMP or something. Unless that Solar Winds hack left all the breadcrumbs needed to exploit all these segregated systems at the same time.
Regional outages are more possible but still not likely. Local outages of course happen often. Texas is not on a regional grid, state power grid.
That’s my limited knowledge - I’m sure someone on this board knows more about power and their ICS environments.
Good to know. I'm in Holland which very rarely has shutdowns but neighbouring Germany (and then Austria) are seriously underpowered which will have a knock-on effect. Sub stations are isolated but progressive management may have cut corners and compromised that security by digitisation. Solaris hack bit worrying.
Hey, checkout the bios of the executives running your utility service to know where you're headed.
