>The equivalent water analogy would be everyone having their own household water cistern in case the water system failed, which I also think is vanishingly rare.
I had a lot of power failures living in Canada, always due to the above-ground power delivery. I'm guessing this would also count for large parts of the US and the developing world. In Europe, I would bet on centralized solutions because the underground power lines rarely fail. But anywhere with above-ground power delivery, having a battery per household makes a lot of sense.
