Power Outage Preparedness Checklist for Homeowners 2026
In February 2024, an ice storm left 2.7 million Texans without power for five or more days. Homes without backup power, water storage, and food supplies faced dangerous conditions within hours. This checklist covers every category of readiness—from backup power and water storage to communication and critical medical needs—so your home stays functional when the grid fails.
Backup Power Systems
The backbone of outage resilience is reliable backup power. Your choice depends on budget, runtime needs, and what you’re powering.
Portable power stations work well for homes that want quiet, low-maintenance backup. The Bluetti AC500 paired with B300S battery modules delivers 5,000W continuous power and can run essential devices for 24+ hours depending on load. The Generac PWRcell offers modular capacity starting at 10kWh, expandable to 18kWh, with 7.5kW continuous output.
Whole-home generators (natural gas or propane) automatically activate during an outage and can power your entire house. A 20kW Generac home standby generator runs most household loads indefinitely with fuel supply. Installation requires professional setup and installed.
Solar plus battery combos provide long-term resilience if your climate permits. A Tesla Powerwall (13.5kWh, 5kW continuous) paired with rooftop solar can sustain critical loads indefinitely during daylight. See our solar power system guide for deeper setup guidance.
Uninterruptible Power Supplies (UPS) protect specific devices—computers, modems, medical equipment—by keeping them alive during the transition to backup power. A CyberPower CP1500AVRLCD provides 1,500VA (900W) for 15–20 minutes, enough time to shut down safely or switch to a generator.
Checklist items: - [ ] Decide on backup power type (portable station, generator, solar, or UPS) - [ ] Calculate your wattage needs for essential appliances - [ ] Purchase and test your chosen system - [ ] Stock fuel (propane, gasoline, or solar panels) for extended use - [ ] Schedule annual maintenance for generators - [ ] Know how to manually start your system if needed
Water and Sanitation
The average person needs one gallon per day for drinking and basic hygiene. A family of four should store at least a two-week supply—56 gallons minimum per FEMA guidance—but more is safer.
Storage options: - Food-grade water containers (5-gallon jugs are standard and stackable) - Water barrels (55-gallon drums for larger households) - Bathtubs filled manually when an outage warning arrives - Water purification tablets or filters as backup
Sanitation deteriorates quickly without running water. A chemical toilet, bucket system, or portable camping toilet prevents disease when municipal sewage systems fail.
Checklist items: - [ ] Store 2+ weeks of drinking water (1 gallon per person per day minimum) - [ ] Keep water purification tablets or a gravity filter on hand - [ ] Stockpile toilet paper, paper towels, and hygiene supplies - [ ] Have a manual toilet solution (chemical toilet, bucket system, or portable camping toilet) - [ ] Rotate water storage every 6 months to ensure freshness - [ ] Label water containers with the date stored
Food and Cooking
Refrigerated and frozen food spoils within hours once power fails. Per USDA guidance, a full freezer stays cold for about 48 hours if unopened; a half-full one for 24 hours. Plan to eat perishables first, then move to shelf-stable foods.
Non-perishable foods to stock: - Canned vegetables, fruits, and proteins (beans, tuna, chicken) - Pasta, rice, oats, and grains - Peanut butter, nuts, and dried fruit - Crackers, granola bars, and other calorie-dense snacks - Powdered milk and infant formula (if needed)
Cooking without electricity: - Camp stove or outdoor grill (never use indoors—carbon monoxide risk) - Canned heat (Sterno) for minimal cooking - Charcoal grill if you have outdoor space - Manual can opener (electric ones are useless during outages)
Checklist items: - [ ] Stock 2+ weeks of non-perishable food per person - [ ] Include foods you actually eat (not just survival rations) - [ ] Have a manual can opener and basic cooking utensils - [ ] Keep a camp stove or grill and fuel outside - [ ] Rotate pantry stock annually to avoid expiration - [ ] Know how long your freezer stays cold (and plan accordingly)
Lighting and Visibility
Darkness compounds panic. Multiple light sources ensure you can navigate safely and maintain morale.
Lighting hierarchy: 1. Flashlights: A Fenix PD35 with two CR123A batteries runs approximately 50 hours on low mode. Keep several flashlights, plus fresh batteries stored in a cool, dry place. 2. Lanterns: Battery-powered or hand-crank lanterns provide ambient light for larger spaces. They’re safer than candles and don’t consume oxygen. 3. Headlamps: Free up your hands while working or moving through the house. 4. Candles: Use only as a last resort—fire risk and oxygen depletion in sealed spaces make them dangerous during extended outages. 5. Glow sticks: Chemiluminescent sticks provide safe, waterproof light for kids and emergency marking.
Checklist items: - [ ] Have at least 3 flashlights per household - [ ] Stock fresh batteries (multiple types: AA, AAA, 9V) - [ ] Keep 1–2 battery-powered or hand-crank lanterns - [ ] Own at least 2 headlamps with spare batteries - [ ] Store glow sticks for emergency marking or child comfort - [ ] Keep candles and matches in a sealed container (backup only) - [ ] Test all lights quarterly to catch dead batteries early
Communication and Information
When the grid fails, internet and cell service often follow. A battery-powered or hand-crank radio keeps you informed of official updates, emergency broadcasts, and weather warnings.
Communication tools: - NOAA Weather Radio: Alerts you to severe weather and emergency broadcasts. - Battery or hand-crank AM/FM radio: Provides news and local emergency information. - Mobile phone chargers: Solar chargers, power banks, or car chargers extend battery life. - Two-way radios (walkie-talkies): Useful if you need to communicate with neighbors or family members in different parts of your home.
Checklist items: - [ ] Have a battery-powered or hand-crank NOAA weather radio - [ ] Keep a portable phone charger with full charge - [ ] Stock extra batteries for all communication devices - [ ] Know the location of your local emergency operations center - [ ] Have a paper list of important phone numbers (cell networks may be down) - [ ] Test your radio and chargers every 6 months
Medical and Medication Needs
Prescription medications, insulin, oxygen, and other critical medical supplies become lifesaving when hospitals are unreachable or overwhelmed.
Medical preparedness: - Keep a 30-day supply of all prescription medications in original containers - Store insulin and other temperature-sensitive drugs in insulated coolers with ice packs - Have a list of your medications, dosages, and any allergies - Stock over-the-counter pain relievers, antihistamines, antacids, and anti-diarrhea medication - Keep a well-stocked first-aid kit (bandages, antiseptic, tweezers, pain relief, antibiotic ointment) - Have backup power for medical devices: CPAP machines, nebulizers, oxygen concentrators, or dialysis equipment
Checklist items: - [ ] Maintain a 30-day supply of all prescription medications - [ ] Store temperature-sensitive medications in a cooler with ice packs - [ ] Create a list of medications, dosages, and allergies - [ ] Stock a comprehensive first-aid kit - [ ] Have backup power for critical medical equipment - [ ] Know how to manually operate medical devices if power fails - [ ] Discuss outage plans with your doctor or specialist
Critical Documents and Cash
Digital records vanish when servers fail. Physical copies of insurance policies, deeds, IDs, and financial records protect your interests when you need to file claims or prove ownership.
Documents to copy and store: - Insurance policies (home, auto, health) - Property deeds and mortgage documents - Birth certificates, passports, and IDs - Medical records and medication lists - Bank account information and financial statements - Utility account numbers and contact information
Cash on hand: ATMs and card readers stop working during extended outages. Keep in and bills in a waterproof container at home for emergency purchases or barter.
Checklist items: - [ ] Make copies of all critical documents - [ ] Store originals and copies in separate, waterproof locations - [ ] Keep copies in a safe deposit box and at home - [ ] Maintain a household inventory with photos for insurance claims - [ ] Store small bills in a waterproof container at home - [ ] Update document copies annually
Heating and Cooling
Power outages in winter can turn deadly without heat. In summer, lack of air conditioning poses heat-illness risks, especially for elderly or very young household members.
Winter heating: - Portable propane or kerosene heaters (use only in well-ventilated spaces; never in sealed bedrooms) - Wood stove or fireplace with a supply of dry wood - Heavy blankets, sleeping bags, and thermal clothing - Insulation materials to seal drafts around windows and doors - Knowledge of safe alternative heat use to avoid carbon monoxide risk
Summer cooling: - Battery-powered or hand-crank fans - Coolers with ice packs - Light-colored, loose-fitting clothing - Awareness of heat-illness symptoms (dizziness, nausea, rapid heartbeat) - A plan to relocate to a cooler location (community center, friend’s house, cooling shelter)
Checklist items: - [ ] Have a safe heating method for winter outages (with fuel supply) - [ ] Stock heavy blankets and thermal clothing - [ ] Keep battery-powered fans for summer use - [ ] Know how to safely operate alternative heaters - [ ] Seal drafts and improve insulation before winter - [ ] Know the location of local cooling centers - [ ] Have a plan to evacuate to a cooler location if needed
Tools and Supplies
Basic tools let you secure your home, clear debris, and make emergency repairs without relying on outside help.
Essential tools: - Multi-tool or Swiss Army knife - Hammer and nails - Screwdrivers (Phillips and flathead) - Adjustable wrench - Flashlight with extra batteries - Heavy-duty tape (duct tape, electrical tape) - Rope or paracord - Crowbar or pry bar - Saw (hand saw or folding saw) - Pliers
Supplies: - Tarps and plastic sheeting (roof leaks, window damage) - Sandbags or sand (flooding) - Nails, screws, and bolts - Heavy-duty trash bags - Cleaning supplies and disinfectant - Work gloves and safety glasses

Home Hardening and Prevention
The best outage is one you’re prepared for before it happens. Hardening your home reduces damage and recovery time.
Preventive measures: - Trim tree branches hanging over your roof (reduces falling-branch damage to power lines) - Install a whole-home surge protector at your electrical panel (such as an Eaton SPD) plus outlet-level protectors for sensitive devices like TVs and computers - Know how to manually shut off gas and water (and keep tools nearby) - Have a battery backup for your garage door opener - Install storm shutters or plywood templates for windows - Reinforce your roof and foundation if you live in high-wind or flood-prone areas - Keep gutters and downspouts clear
Checklist items: - [ ] Trim overhanging branches before storm season - [ ] Install whole-home surge protection at your electrical panel - [ ] Install outlet-level surge protectors for TVs, computers, and appliances - [ ] Learn how to manually shut off gas and water - [ ] Have a garage door backup power or manual release - [ ] Prepare storm shutters or plywood for windows - [ ] Inspect roof and foundation annually - [ ] Keep gutters and drainage clear
Family Communication and Evacuation Planning
When an outage hits, your family may be scattered across town. A communication plan ensures everyone knows where to meet and how to reconnect.
Communication plan: - Designate an out-of-state contact person (local networks may be overwhelmed) - Teach children the contact person’s phone number - Establish a meeting place if you can’t return home - Agree on a secondary meeting location outside your neighborhood - Store contact information on paper (not just your phone)
Evacuation readiness: - Keep a “go bag” with essentials (medications, documents, cash, clothes) - Have a pet evacuation plan (carriers, food, medical records) - Know the routes out of your neighborhood - Keep your vehicle fueled above half-tank during storm season
Checklist items: - [ ] Choose an out-of-state contact person - [ ] Teach family members the contact’s phone number - [ ] Establish primary and secondary meeting locations - [ ] Create a written family communication plan - [ ] Prepare a go bag with essentials - [ ] Have a pet evacuation plan - [ ] Keep vehicle fuel above half-tank during high-risk seasons
FAQ
How long should I plan for in a power outage? Most utility outages last under 24 hours, but major events can stretch weeks. Plan for at least 2 weeks of self-sufficiency (water, food, medications, heat or cooling). If you live in a rural area or high-risk region, aim for 30 days.
What backup power do I need if I have a CPAP machine? A CPAP typically draws 40–60W. A portable power station like the Bluetti AC500 with B300S modules can run a CPAP for 3–5 days on a single charge. For longer outages, pair it with solar panels or add a second battery module. A whole-home generator is ideal if you use a CPAP nightly and want indefinite runtime.
How do I keep insulin cold during a 3-day outage? Store insulin in an insulated cooler with ice packs or a passive cooling device designed for medications. Insulin remains viable at 36–46°F for weeks. Pre-freeze ice packs the day before an expected outage, and minimize cooler opening. If ice melts, replace it with fresh ice or use a backup cooler. Have your doctor discuss cold-chain options specific to your insulin type.
Is a portable power station enough, or do I need a generator? Portable power stations work well for essential devices and short outages (under 3 days). Generators or solar systems are better if you want to run larger appliances or prepare for extended outages. See our home backup power systems guide to compare options.
How often should I rotate my emergency supplies? Check expiration dates on food and medications every 6 months. Rotate water every 6 months if stored in opaque containers; every 1–2 years if sealed. Test batteries, flashlights, and radios quarterly.
What’s the most important thing to have during a power outage? Water. You can survive weeks without food, but only days without water. After water, prioritize medications and a way to stay warm (winter) or cool (summer).
Summary
A robust power outage preparedness checklist covers six critical areas: backup power, water and sanitation, food and cooking, lighting, communication, and medical needs. Add tools, home hardening, and a family communication plan, and you’ve built a household that can function independently for weeks.
Start with the essentials—backup power, water, food, and medications—then expand to comfort items and home hardening. Test your systems quarterly, rotate supplies every 6 months, and update your checklist annually. When the grid fails, you’ll be ready.
