I did the same just before our massive ice storm and snow storms not long ago.
Natural gas for heat and cooking, propane backup, Coleman stove backup, Sterno cans for more back up. I lit kerosene lanterns I haven’t used for 25 years, had Coleman lanterns for back up and finally candles.
We did well with no electricity for several days and below “0” temps.
Every now and then, my electric grid goes down; for varying lengths of time.
After one particular worrisome event; I finally bought a generator that could handle all the big appliances in the house.
I have no ‘transfer switch’ (the things are just TOO expensive for the function they do), I merely pull the main breaker, and plug the generator into the 220 welding outlet in the barn and backfeed the house.
When I find the neighbors have lights, I can shut’er down ‘til the next time!
