At least in my area (NJ) we lose power around a week on a good year, approx 2 weeks out on a bad year. Outages usually caused by trees falling during thunderstorm/wind, sometimes snow, not hurricane. Oh and drunks slamming into poles. Everyone has generators or other forms of backup power in my area.

But problem in recent years was the dead ash trees from emerald ash borer, they took a few years to fully die and weaken but now they just collapse into lines on a good wind gust.

Localities that have their own utilities never go down (Madison, NJ), my area is covered by Firstenergy that cheaps out and keeps only a skeleton crew in NJ, so when stuff like the poles snap at end of my driveway it takes 3-4 days to send crews from texas or ohio to replace it.
