10-second answer: Winter blackouts kill through cold + carbon monoxide mistakes, not hunger. Priorities: one safe heat source, 14 days water, battery CO detector, NOAA radio, and a warm room plan before you touch luxury gear. Budget warm-room setup: ~$120. Standard with generator + propane: ~$850.
Ice loads snap power lines. Furnaces stop. Pipes freeze. A summer blackout is inconvenient; a winter blackout can hospitalize your family in a single night. This guide is for sheltering at home when restoration might take days — not wilderness camping.

Why Winter Changes Everything
Hypothermia risk rises when indoor temps drop below 50°F for extended periods. Electric heat, heat pumps, and most modern furnaces need grid power. Your 72-hour summer kit is a start — but winter adds heat, pipe protection, and ventilation math that summer outages skip.
Step 1 — Designate a Warm Room
Pick the smallest interior room with few windows — often a bathroom or closet. Hang blankets over doors, roll towels along thresholds, and keep everyone in one space. Body heat plus one safe heater beats heating the whole house.
Never run propane, charcoal, or gasoline combustion indoors without ventilation. Crack a window when using a vent-free propane heater.
Step 2 — Backup Heat Without Killing Yourself
- Mr. Heater Buddy + 20-lb propane tank — room heat for days; store tanks outside
- Battery CO detector — hardwired detectors die with the grid
- Generator outside only — 20+ feet from windows; dual-fuel runs on propane that stores indefinitely
Step 3 — Water, Food, and Frozen Pipes
Store 1 gallon per person per day for 14 days in winter — you may not want to melt snow. Pre-cook chili and freeze in bags before storms; they thaw slowly and act as ice packs.
If heat is lost: shut main water valve, open faucets, add RV antifreeze to traps, wrap exposed pipes with foam wrap.
