We had a big, for us, snow storm last Feb. 7" of snow, which is about a 5 year accumulation normally. Was without power for a week. I just drug out my gen and ran that till we got power back. Had to siphon gas out of the truck but it was there, fresh and did what I needed. Didn't try to run the whole house, just one room with a space heater and a fireplace. Wasn't worried about refrigerator or freezer, that part of the house was as cold as a fridge anyway. Used the grill and microwave, didn't power the electric stove.

Biggest problem we had was right after we got power back we lost water, water main breaks. So I was melting snow for flushing purposes. Several 5 gallon buckets on standby in the tub.

If it was summer time instead, I'd power the fridge and freezer and a couple fans. I do have a couple window units in storage I could drag out if I got too sweaty.

You do what you gotta do I guess.

Good luck.
