I don't agree with OP in that I think power reliability is a concern with EVs. However PGE does not handle power for SoCal. In SoCal you have San Diego Gas and Electric(SDGE), LA Dept. of Water and Power, Southern California Edison, and maybe others. PG&E, along with its numerous problems, is NorCal.

I lived in SoCal for 24 years and the only major(>3 hours) power outage I remember was https://en.wikipedia.org/wiki/2011_Southwest_blackout and IIRC it lasted less than a day. That said, a major seismic event could occur anywhere in CA and cause outages for much longer than that.

    PG&E's safety outages are a fact of life of living in California

Is this due to natural disaster risk or lack of maintenance for infrastructure? I've lived in Austria & Germany for 15 years now and only once experienced a power outage (I think it lasted about 15 minutes).

It’s because their electric grid equipment has been the source of ignition for wild fires in the past and the state fined them for causing fires which in part drove them into bankruptcy last year. So to avoid fines they cut off power whenever conditions make fires likely. Their poor financial management over decades is also likely responsible for poor equipment maintenance which increases likelihood of equipment causing fires.

A fact of life in the past couple of years only. It's a(n over)reaction to their legal woes, and I suspect it will snap back as regulators crack down on these actions.
