Let's see, I've lived within 5 miles of where I do my entire life, and my parents lived there for 54 years - in those 54 years, the power has gone out 5 times, the longest for about 36 hours, most of them for less than 12

For some reason I'm not too worried. That said, when I rebuild the house next year, there is a real good chance I'm putting in a whole house genset, as I think the grid is getting worse - 3 of those 5 times are in the last 5 years
