Before the outage
Build the plan while every store, road, and outlet still works. Photograph the electric-panel directory, label cords and adapters, and write a one-page startup sequence for backup equipment. Every adult who may be home should be able to use the system safely.
- List medical devices and required runtime; ask providers about backup plans.
- Install and test smoke and carbon-monoxide alarms with battery backup.
- Store at least one gallon of water per person per day, adjusted for household needs.
- Keep appliance thermometers in the refrigerator and freezer.
- Charge power stations, radios, flashlights, phones, and tool batteries.
- Test generators outdoors under load; inspect oil, fuel, cords, and transfer equipment.
- Download local utility and emergency-alert information for offline access.
- Keep cash, prescriptions, pet supplies, and a manual can opener available.
First 15 minutes
Determine whether the outage is limited to the home or affects the neighborhood. Check for fire, damaged wiring, gas odor, downed lines, flooding, or anyone dependent on powered medical equipment. Call emergency services for immediate hazards and stay well away from downed lines.
Unplug sensitive electronics if surge protection is uncertain. Leave one light switched on so restoration is obvious. Do not open the refrigerator or freezer while deciding on the power plan.
Refrigeration and food
An unopened refrigerator provides only a limited safe window. A full freezer holds temperature longer than a half-full freezer. Track time and temperature, group frozen items together, and use coolers and ice when available. Never taste food to decide whether it is safe.
If backup power is limited, refrigeration usually outranks entertainment and convenience loads. Cycle other devices around the compressor and monitor temperature with an appliance thermometer.
Generator operation
Move the generator outdoors at least 20 feet from doors, windows, and vents, point exhaust away, and keep it dry without enclosing it. Connect through the professionally installed transfer equipment or correctly sized outdoor cords planned in advance. Never backfeed a home.
Let the generator cool before refueling. Track operating hours, fuel level, and maintenance intervals. A CO shutoff feature does not replace placement rules or working alarms.
Battery and power-station operation
Connect only the prioritized loads. Turn off unused AC outlets because the inverter itself consumes energy. Use direct DC or USB outputs where practical, keep vents open, and check remaining watt-hours rather than relying only on a percentage estimate.
Recharge during utility restoration windows or good solar conditions. Keep lithium batteries within the manufacturer's operating and charging temperature range, especially in freezing weather.
Water, heat, and communication
A power outage can stop a private well, water-treatment plant, or electrically controlled heating system. Fill approved containers early when an outage is forecast, conserve stored water, and follow boil-water or do-not-use notices exactly.
Use layered communication: phone alerts, battery radio, vehicle radio, and an out-of-area contact. Conserve phone power and use text messages when networks are congested. Never use a grill, camp stove, oven, or unvented combustion heater as an improvised indoor heat source.
After restoration
Restore loads gradually, verify stable power, and inspect cords and equipment for heat or damage. Follow food-safety guidance using time and temperature. Recharge every battery, perform any generator service due, rotate or replace fuel, clean water equipment, and restock consumed items.
Write down what worked, what was missing, and actual appliance consumption. That short after-action note is more valuable than buying another random piece of gear.
Frequently asked questions
What should I power first?
Life-safety medical equipment comes first, followed by refrigeration, water-system needs, communications, basic lighting, and temperature control appropriate to conditions.
How long is refrigerator food safe without power?
Federal guidance says an unopened refrigerator keeps food cold for about four hours. Use a thermometer and official discard guidance rather than smell or taste.
Should I turn off the main breaker?
That depends on the cause of the outage and your transfer setup. Follow utility and electrician instructions; never connect a generator without an approved method that prevents backfeed.
