When Oklahoma went through this a year ago most folks had power back on in 3-7 days but there were some that went twice that long. Very few went more than a month.

One of the primary bottlenecks was the lack of electrical contractors to re-install the power heads on the side of homes. In many cases when the power lines were pulled down the power head on the house was damaged or ripped off entirely. The utility company is typically only responsible for getting the power to the pole nearest your house & they won't connect to an electrical system that is damaged.

At least in that storm, if you lost power, a three day outage was pretty much a best case.
