I would guess no role at all. The government agencies in all those counties have back up power so they will be able to communicate. I think anyone, anywhere, who must have electrical power for life support equipment would be well advised to have a B/U generator. We have always had one even though we don't need it for medical equipment. In the years we lived in one of the impacted CA counties (SHASTA) we had a generator and used it a few times. The longest period was 4 days when a huge wind storm knocked out power poles/lines from Chico to Redding. One other time was when a forest fire took out some power lines that fed our place BUT the electric company was quick to replace those.
