Understanding what happens during a grid-down emergency is one thing. Knowing exactly what to do — in what order, without hesitation — is another. This guide is the second kind. It assumes the power is already out and you have decisions to make.

The Moment the Power Goes Out: First 15 Minutes
Your first instinct will be to wait and see. Override it. Use these first 15 minutes before you know anything about scope or duration:
- Check your breaker box — rule out a local trip before assuming a wider outage
- Look outside — are neighboring homes dark? Street lights out? Wider outage confirmed
- Turn on a battery or hand-crank radio and find your local emergency broadcast frequency
- Text (don't call) family members to confirm their status — texts route through congested networks far better than voice calls
- Start filling every container you have with tap water — do not wait on this
Hours 0–2: Secure Your Resources
Once you've confirmed a real outage, your job is to stop the bleed on your resources before the situation outside deteriorates. Move through this list in order:
- Water: Fill bathtub, all pots, all containers. A WaterBOB bladder (100 gallons) is ideal if you have one. If not, the tub itself buys you significant reserve
- Power: Charge every device from your car's USB ports or inverter — phones, power banks, laptops, radios. Do this now while fuel is in the tank
- Food inventory: Open your fridge once, quickly, and mentally note what's there. Close it. A full fridge holds temperature for approximately 4 hours — don't bleed that by browsing
- Cash: If you don't have cash at home, an ATM run in the first hour may still be viable. By hour three, lines will be long and machines may be empty
- Fuel: If your vehicle is below half a tank, consider a fuel run in this window. By hour four, station lines will be significant
Hours 2–6: Establish Your Information Picture
You cannot make good decisions without good information. By hour two, social media is unreliable, cell service is degrading, and rumor is filling the vacuum. Your job is to stay on signal.
- Stay tuned to your emergency broadcast radio — NOAA and local emergency management will issue updates on scope and estimated duration
- Do not rely on social media for factual information — treat it as noise unless it corroborates official broadcasts
- Reach out to one trusted contact outside the affected area — they have internet access and can relay information you can't get locally
- Make a preliminary stay-or-go assessment based on what you know: water supply, household medical needs, your destination options
Hours 6–12: Manage Temperature and Food
By the six-hour mark, comfort becomes a survival variable — particularly in extreme weather. Address your thermal situation before it becomes urgent.
In summer heat: Close blinds and curtains on sun-facing windows. Move to the lowest floor — heat rises. Identify the coolest room in the house and plan to consolidate there if temperatures climb. Know your most vulnerable household members — elderly, infants, and those with certain medical conditions are at risk from heat far sooner than healthy adults.
In winter cold: Identify your heat source — a wood stove, propane heater, or simply the best-insulated room in the house. Consolidate bedding, people, and pets into one room. Seal gaps under doors with towels. A well-insulated home loses roughly 1–2°F per hour without heat, so you have time — but not unlimited time.
Food sequence: Begin working through food in this order:
- Refrigerated perishables first — meat, dairy, leftovers (consume within 4 hours of outage)
- Freezer items second — a full freezer holds for 24–48 hours if unopened
- Shelf-stable and preserved foods last — these are your long-game supply
Hours 12–24: Reassess and Decide
At the 12-hour mark you have enough information to make your first real strategic decision: are you staying, or are you preparing to move?
Run this assessment honestly:
- Water: how many days of supply do you have at current household consumption?
- Food: how many days of shelf-stable food are available without resupply?
- Temperature: can you maintain a survivable temperature for 72+ hours?
- Medical: does anyone in your household have a need that cannot be met at home beyond 24 hours?
- Security: is your immediate environment stable?
If you answered yes to all five — you stay. If any answer is no, start planning your exit now rather than waiting for the situation to force your hand.
Hours 24–48: Execute Your Plan
By day two, improvisation should be over. You are either settled into a sustainable home situation or you are moving. Both require deliberate action:
If staying: Establish a daily routine — rationing, monitoring your supplies, staying informed, maintaining morale. Structure matters psychologically in extended emergencies. Assign roles if you have household members. Know your next decision point: at what supply level do you reassess the stay-or-go question?
If moving: Execute your bug-out plan — confirmed destination, loaded vehicle, bug-out bags for every member, important documents in a waterproof bag. Depart in daylight. Take secondary roads where possible. Tell someone outside the area where you're going and your expected arrival time.
The first 48 hours are where preparation either pays off or it doesn't. The decisions you make in this window — most of them in the first six hours — determine the trajectory of everything that follows. Make them early, make them deliberately, and make them from information rather than fear.
