Yeah here in the Midwest my area lost power due to the polar vortex around the winter solstice a few years back. Did it suck? Yeah. But towels under doors, ready to eat food, candles, and lots of blankets made it merely unpleasant. You absolutely should have supplies for situations like that. At some point I’d also like to keep drinking water supplies. Your emergency preparedness kit is generally best to keep at “bearable” levels for a few days. The goal is to ride it out, not to experience full comfort.
