My read is that the east is more vulnerable than the populated areas of the west because of the assumptions that (a) any event would be regional and (b) a few transformers may be dealt with without issue, and a few more is an inconvenience. Only where the number of large transformers is concentrated within a region would one run into insurmountable difficulties.
Problem is, when the lights go out, the areas they (the power companies, government,etc) concentrate on getting restored first are the high-density population centers. IE, the voters.
I live in what I would not call remote, but would call removed area. Usually, if the power goes out, they always get it turned back on in the towns and suburbs, rather than here.
So I’m pretty set up, I could go a couple weeks on generator.
