We had to throw out the chest freezer contents only once in the last 20 years or so due to a power outage, so it hasn't been big issue where we live. Saving a couple of hundred dollars a month or more by stockpiling freezer foods on sale / bulk Costco size packages for us still outweighs the risk having a power outage, unless we started having longer outages. Whenever we use up some of the freezer foods, I add in containers of water that freeze solid to keep the freezer packed full. It helps the freezer to use less electricity and keeps things cold pretty cold through most power outages. We only had the one I can remembers where it was long enough that even my large, solid ice packs couldn't save the contents.
Might be a good idea to pick up a small gasoline powered generator for those times, if California will allow you to own a few gallons of gasoline that's not in an auto fuel tank.
