Power Outage Prep

Power Outage Preparation: What to Do Before the Lights Go Out

Most power outage problems are completely preventable with a few hours of advance preparation. Here's a practical guide for households at every level.

Power outages are the most common emergency most households will experience. A few hours without power is inconvenient. A few days can be genuinely difficult — especially in extreme cold or heat. But the difference between a miserable outage and a manageable one is almost entirely preparation, and most of that preparation takes less time than you'd think.

This guide covers what to do before an outage, what to do during, and what to pay attention to when power is restored. We'll go from the basics all the way through extended outage planning.

Before: Building Your Outage Readiness

Light and Visibility

The most immediate impact of any power outage is darkness — especially if it happens at night. Get ahead of this:

  • Flashlights — one per household member in a known, consistent location. LED flashlights last for hours on a set of batteries.
  • Headlamp — hands-free lighting is genuinely more useful than a handheld flashlight for most tasks. One or two per household.
  • Extra batteries — store more than you think you need, in the correct sizes for your flashlights.
  • Battery-powered lanterns — better for illuminating a room than a single flashlight.

Keeping Your Phone Working

Your phone is your connection to information, emergency alerts, and family. Keep it alive during an outage:

  • A quality portable power bank (10,000 mAh minimum) can charge most phones 2–3 times. Keep it charged — many people discover their power bank is dead when they need it.
  • A car charger as backup — your car's battery can charge devices for extended periods without running the engine for more than 15–20 minutes at a time. Never run a car in a closed garage.

Staying Informed

When cell networks congest during a regional outage, internet-based notifications may fail. A battery-powered or hand-crank NOAA weather radio receives emergency alerts independent of the internet or cell network. This is consistently one of the most useful pieces of emergency equipment you can own.

Food and Water During an Outage

Know the food safety timeline and prepare accordingly:

  • A full refrigerator stays safe for 4 hours after power loss if the door stays closed. A half-full refrigerator is safe for 2–3 hours.
  • A full, unopened freezer keeps food safe for 48 hours; half-full for 24 hours.
  • When in doubt, throw it out. Food poisoning during an emergency is a serious complication.
Food Safety Verification The FDA's FoodSafety.gov and the USDA both publish updated food safety guidelines for power outages, including specific guidance by food type. When in doubt during an actual outage, their charts are the most reliable reference.

Keep shelf-stable food on hand for outages: canned goods, peanut butter, crackers, granola bars, dried fruit. These don't require refrigeration or cooking.

Heat and Cold Safety

Extended outages in extreme heat or cold become dangerous. Plan ahead:

  • Cold weather: Know which room in your home is easiest to heat passively (typically smallest, south-facing, most insulated). Have sleeping bags or extra blankets ready. Know where your local warming shelter is.
  • Hot weather: Know where your local cooling center is. Have battery-powered fans. Stay hydrated. Check on elderly neighbors and family members — heat is particularly dangerous for older adults.
Generator Safety — Critical Generators must be operated outdoors, at least 20 feet from doors and windows. Never use a generator, grill, camp stove, or other combustion equipment indoors. Carbon monoxide is odorless and can be fatal within minutes. Install battery-powered CO detectors and test them regularly. Verify current generator safety guidance with your local fire department or the Consumer Product Safety Commission.

During: What to Do When the Power Goes Out

  • Turn on a flashlight and locate all household members.
  • Check if neighbors have power — this helps you determine if it's a local issue or widespread outage.
  • Report the outage to your utility company.
  • Unplug major appliances and electronics to protect them from power surge when electricity returns. Leave one light on so you know when power is restored.
  • Minimize refrigerator and freezer door openings.
  • Monitor temperature in your home, especially in extreme weather.
  • Listen to your weather radio for emergency broadcasts.

After: When Power Returns

  • Wait a few minutes before plugging major appliances back in — let the power stabilize.
  • Check your refrigerator and freezer using the food safety guidelines.
  • Recharge your power bank and flashlight batteries.
  • Note what you wish you'd had and add it to your preparedness plan.

Extended Outage Planning (48+ Hours)

If an outage lasts more than two days, the challenges increase. Food safety becomes a serious concern. Heating and cooling become critical. Here's what to think about for extended situations:

  • Know your fuel options for cooking without power: propane camp stove (outdoor use only), solar oven, or a wood-burning fireplace if you have one.
  • Know where to go if your home becomes unsafe: a friend or family member's home, a hotel, a public shelter.
  • Monitor local news and utility company updates for restoration estimates.
  • Check on neighbors, especially elderly, disabled, or those with medical equipment that requires power.
