Stay safe, comfortable, and ready with comprehensive strategies for surviving prolonged power outages in any environment.

Preparing for an Extended Power Outage

Power outages can strike with little warning, disrupting daily life and posing serious risks to safety, comfort, and health. While the average outage may last only a few hours, storms, infrastructure failures, or attacks on the grid can leave you without electricity for days or even weeks. Preparation is key to minimizing disruption and protecting your family.

Why Prepare for Extended Outages?

Major threats such as hurricanes, wildfires, floods, and even cyber-attacks can disable electric grids for long periods. Unlike brief outages, these events can paralyze entire regions, impacting food supply, communications, healthcare, and daily living. Individual preparedness enhances resiliency beyond the government’s response systems, allowing households to manage safely and independently.
Key risks during extended outages:

Food spoilage
Water supply interruptions
Loss of communication
Extreme temperatures
Medical device failures
Sanitation hazards

1. Assembling Your Emergency Preparedness Kit

A well-stocked emergency kit is the cornerstone of power outage preparedness. It should meet your family’s basic needs for at least two weeks.

Food: Stock up on non-perishable items like canned meats, vegetables, soups, peanut butter, granola bars, dried fruits, nuts, and sports drinks. Rotate stock and select foods that need no refrigeration or cooking.
Water: Store at least one gallon of water per person per day. For hot climates or those with greater needs (elderly, children, pregnant), increase storage. Include purification tablets or a water filter.
Alternative cooking methods: Battery-powered grills, solar ovens, or camp stoves (never indoors) can help you cook safely without power.
Lighting: Flashlights, lanterns, candles (use with caution), glow sticks, and extra batteries. Headlamps keep hands free.
Medical supplies: Stock a basic first-aid kit, essential prescription medications, and supplies for anyone with special medical needs (e.g., insulin, oxygen, battery-powered devices).
Communication devices: Battery-powered or crank emergency radios, extra batteries or power packs for phones, and chargers.
Personal hygiene: Include moist towelettes, hand sanitizer, trash bags, and personal hygiene products.
Pets: Food, water, medications, and comfort items for pets.

2. Creating Your Emergency Plan

Advanced planning creates confidence and ensures everyone knows what to do when the lights go out.

Evacuation plan: Identify safe places to go if your home becomes uninhabitable due to temperature, damage, or lack of resources. Include a plan for pets.
Communication plan: Keep a paper copy of contact lists. Designate an out-of-town contact. Know how to reunite if separated.
Alert systems: Sign up for local alerts and weather warnings. Maintain access to news via battery-powered radios or emergency apps.
Support network: Identify neighbors or friends who can assist, especially for those with medical or mobility challenges.
Power needs inventory: Make a list of devices and appliances that require power, plus alternatives for lighting, communication, refrigerated medication, and cooking.

3. Food Safety and Refrigeration

Without electricity, refrigerators and freezers gradually lose their ability to keep food safe. Take the following steps to minimize food loss and prevent foodborne illness:

Keep refrigerator and freezer doors closed as much as possible to retain cold.
Use coolers with ice to extend food refrigeration. Store extra ice packs if possible.
Keep a thermometer in your fridge, freezer, and coolers. Refrigerators should stay below 40°F (4°C), freezers below 0°F (-18°C).
After 4 hours without power, perishable foods begin to spoil. Discard anything exposed to temperatures above 40°F for more than 2 hours.
Plan meals around perishable foods first, then shift to shelf-stable supplies as needed.

4. Water Safety and Storage

Municipal water systems may fail during outages, especially in rural areas. Preparation is essential:

Store drinking water in clean containers.
If unsure about water safety, boil (if possible) or use purification tablets or a water filter.
Keep enough water for drinking, cooking, and basic hygiene.
Consider rainwater collection systems (check local regulations).

5. Heating, Cooling, and Shelter

Maintaining a safe temperature is critical.

Insulate your home: Seal windows, close blinds, and use blankets.
Hot weather: Move to designated cooling centers, use battery-powered fans, avoid outdoor activity.
Cold weather: Wear layers, use sleeping bags, and gather in a single room. Do not use outdoor stoves, generators, or grills indoors – they release deadly carbon monoxide.
If unsafe, evacuate to a location with heat or air conditioning.
Keep emergency blankets available for each person.

6. Medical and Personal Needs

Take an inventory of medical requirements for all household members.

Have backup power sources for critical devices (batteries, manual alternatives).
Store sufficient medication for at least two weeks.
Consult with healthcare providers about alternative arrangements for power-dependent equipment.
Keep a list of local hospitals and clinics that may be less impacted by outages.

7. Lighting and Power Alternatives

Maintain visibility and comfort after dark:

Use battery-powered lanterns, LED flashlights, or headlamps.
Glow sticks are safe for young children or as night lights.
Candles can provide light but require constant supervision due to fire risk.
Solar lights can recharge during the day for night-time use.

8. Safe Generator Use

A generator can restore key functions but must be operated safely:

Place generators at least 20 feet from your home.
Never run a generator indoors or in garages (carbon monoxide risk).
Keep the generator dry – avoid rain and flooding.
Keep doors and windows closed while a generator runs.
Turn off and let cool before refueling.
Unplug electronics before starting the generator.
Use only with professionally installed transfer switches.

9. Protecting Electronics and Surge Prevention

Power surges can damage sensitive electronics when electricity is restored. Take preventive measures:

Install surge protectors for computers, TVs, and other critical devices.
Unplug devices before an outage if possible.
Wait until stable power returns before plugging things back in.

10. Smoke and Carbon Monoxide Alarms

Outages increase fire and carbon monoxide risks due to alternative heating and lighting methods.

Install smoke alarms with battery backups on each floor and sleeping area.
Use at least one carbon monoxide detector per level.
Test alarms monthly and replace batteries regularly.

11. Sanitation, Hygiene, and Waste Disposal

Without water and electricity, sanitation can quickly deteriorate.

Stock up on hand sanitizer, moist towelettes, and trash bags.
Prepare portable toilets or buckets for waste if plumbing stops working.
Separate waste and dispose of it safely when possible.
