In other words, same as usual.
The big problem in these situations is not people getting cold or freezing (houses keep the wind off and everybody who lives in rural Alaska has more than one source of heat.
The problem is water and sewer lines, if left un-used will freeze and that means total replacement of an entire village sewer system.
Happened in Bethel Alaska, a few years ago where the Generator Building burned down, and destroyed the generators and switch gear. Because no warm water was flowing thru the sewer, it froze and burst pipes all over town and was a total write-off. It was back to honey-buckets.
