If you are having a widespread, long term power outage, those gas pumps will not run due to not having electricity.
Do you live in an area that has frequent power outages, then maybe this would be a concern, but in most areas an outage is pretty rare and are short term. If your area has unreliable power, perhaps they should be putting more power transmission lines underground?
Yes, PG&E cuts power proactively via their PSPS program. It doesn't affect most gas stations though, as they are more centrally located and not in neighborhoods. I believe they have looked into burying transmission lines, but found it to be economically infeasible.
