Cutting power *for days* for millions of people is the most INSANE thing I've ever heard of. I can't believe this is happening in the United States. (But not surprised at anything anymore that happens in California)
You should have no power problems in Belmont and SF. Power in the built-up areas is not very vulnerable because it is underground or easily maintained and no built-up flammable debris is littering the ground (other than possibly dried poop in SF). The shutdowns are mostly in and around forested areas where they haven’t kept vegetation from intruding on the lines and where environmentalists have been resisting cleanup of dry brush, debris and dead trees.
