3 of my 4 adjacent neighbors have natural-gas generators. That gives you an indication of the power reliability here. Note that I don't blame the utility, and I'm not in some backwater ($1M+ homes around me). It's just that we really like our trees here, and sometimes a branch will break in a storm and take out the neighborhood.

My gripe with the generators is they are noisy. A Powerwall would be silent and would handle the typical outage situation. But so probably would a 3000VA UPS, which would only cost $1500.
