Elderly Monitoring, Power Outages & Battery Backup (2026 Data)

How long US power outages last now (and why 2024 was different)

How long is the typical US power outage? In 2024, the average customer went without power for about 11 hours across the whole year, which the U.S. Energy Information Administration calls the most hours without power in the United States in 10 years (EIA). That single figure, the System Average Interruption Duration Index including major events, is the headline that makes outages a senior-safety question rather than a utility footnote.

The 11 hours did not come from everyday flickers. Interruptions attributed to major events, such as hurricanes and large storms, averaged nearly nine hours per customer in 2024, compared with an average of nearly four hours per year over 2014 to 2023 (EIA). In other words, a handful of severe weather events drove the bulk of the year's lost-power hours, which is exactly the kind of multi-hour or multi-day outage that puts a person who lives alone at risk.

Strip out those major events and the picture is calm: everyday service interruptions routinely average about two hours per year per customer (EIA). That gap, roughly two hours in a normal year versus about 11 hours in a year shaped by big storms, is the planning problem. Most of the time the lights stay on, so it is easy to feel prepared. The risk concentrates in the rare, long, weather-driven outage that arrives all at once, and that is the scenario a household with an older adult should plan around.

How many at-risk people depend on power for medical care

An outage is an inconvenience for most homes. For a large group of older and medically fragile adults, it is a medical event. Over 4.6 million Medicare beneficiaries who live independently rely on electricity-dependent durable medical equipment and/or certain essential health-care services, according to the HHS emPOWER program (ASPR / CMS). emPOWER de-duplicates that count and refreshes it monthly, so it is a current, rolling measure of how many at-risk people a sustained outage can endanger, not a one-off survey.

Within that population, over 3 million have a claim for electricity-dependent durable medical equipment, such as home ventilators, oxygen concentrators, and powered suction or feeding pumps, and over 2.8 million have a claim for at least one of four essential services: facility-based dialysis, home oxygen, home health, and at-home hospice (HHS emPOWER). For these people the power going out is not about a dark living room; it can mean a ventilator alarm, an oxygen concentrator falling silent, or a dialysis appointment that cannot happen.

Many of these adults also live alone, which compounds the risk. The same outage that threatens the equipment can also take out the home phone, the cordless handset base, and eventually a mobile phone once it drains, removing the very channels a person would use to call for help. The question every family should ask is not only "is the equipment backed up?" but "if the power and the phones go down at once, who would know, and how fast?"

The outage-risk picture on one scale

Putting the duration data beside the at-risk population shows why a long, weather-driven outage is a senior-safety event and not just a utility statistic. The everyday baseline is short and survivable for almost everyone; the major-event scenario is the one that lasts long enough to drain device backups, deplete phone batteries, and silence the channels a person would use to ask for help.

Practical battery-backup steps for an older adult who lives alone

Battery backup for an older adult living alone is about ordering by life-safety, not by gadget. Start with anything medical. If a person uses an oxygen concentrator, a ventilator, a CPAP that is medically required, or a powered feeding or suction pump, talk to the equipment supplier and the prescribing clinician about a backup power plan: a properly sized battery or portable power station, a tested run-time, and a clear threshold at which the person should relocate to a facility or a relative with power. Equipment makers publish backup options; the supplier should specify what is safe for that device, since running medical equipment off an undersized or incompatible battery can be dangerous.

Keep communication alive next. A power outage that takes down a home phone and, eventually, a mobile phone is what isolates someone. Keep at least one charged power bank reserved for the phone, register the address with the utility as a medical-needs or priority-restoration account where that program exists, and make sure at least one phone in the home does not depend on mains power to work. Add light and warmth: battery or hand-crank lanterns near the bed and the bathroom to prevent a fall in the dark, and a plan for staying warm or cool depending on the season and the climate.

Finally, plan the human side before the storm, not during it. Decide in advance who checks on the person and when, agree on a relocation trigger if the outage runs long, and keep a written copy of medications, equipment models, and emergency contacts somewhere that does not need power or a charged screen to read. The technology buys time; the people are what turn that time into action. Treat the battery plan and the who-checks-on-them plan as two halves of the same preparation, because in a long outage you need both.

This is general preparedness information, not medical advice. Decisions about medical-equipment backup power should be made with the device supplier and the prescribing clinician, and life-threatening emergencies always warrant a call to 911.

Where a free daily check-in fits, honestly

I'm Alive is a free daily self check-in app. There is no hardware, no wearable, no pendant, and no fall sensor. It works the opposite way to an alert button: the person confirms they are OK by a time they choose, and if that check-in is missed, their chosen contacts are alerted and escalated. The promise is simple: someone notices if something is wrong, the same day, without the older adult having to call anyone.

We will be honest about the limits on this page, because honesty is the point. I'm Alive runs on a phone, so a prolonged outage that kills the phone or the connection could itself stop a check-in. That is not a flaw to hide; it is exactly how the safety net is designed to work. A missed check-in is the signal. If the power is out, the phone is dead, and the confirmation does not arrive, the app does what no medical-equipment battery can: it prompts the family to physically go and check on the person. The missed reply becomes the human tripwire that converts "I assumed they were fine" into "someone is on their way."

So I'm Alive is not a battery backup for a ventilator or an oxygen concentrator, and it should never be treated as one. It is the layer that sits on top of the battery plan. Pair real backup power for medical devices, registered priority restoration, and a charged phone power bank with a daily check-in, and you cover both halves: the equipment keeps running for a while, and if anything goes wrong beyond that window, a person finds out quickly instead of by chance.

The daily self check-in is free forever. A one-time Lifetime upgrade is $4.99. Family adds contact alerting and escalation for $29.99 a year with a 7-day trial, and Family Plus adds an AI voice agent and emergency location for $39.99 a year. There is no contract, no activation fee, and no cancellation fee. For a household preparing for the next long outage, the alerting tier is the part that makes a missed check-in reach the right person fast.
