Where I live in TN we’ve always had what I call “dirty” power in that the supplier often has surges and occasional stoppages that can run from a few minutes to several hours. We’ve also had a huge snow storm and a tornado, each of which cut off power for several days. My solutions have been to put surge protectors on all my outlets that have attached electronics and to get an all house automatic propane powered generator with a 500 gal. tank that will run the house for about 400 hours. My advice to people in CA is to do the same. Of course, with the PG & E problems the costs of auxiliary power rigs and propane are likely to skyrocket. Here in E TN propane runs about $4.00/gal.
