States With the Longest Power Outages in 2024
This study uses EIA outage-duration reporting to translate state-level power interruption data into practical home backup lessons.
Why this matters for backup power planning
Average outage numbers hide the real household problem: outage risk is uneven. Some states have brief interruptions most years. Others can see long-duration disruptions when hurricanes, winter storms, vegetation, flooding, or local grid conditions hit. Backup planning should be based less on a national average and more on the kind of outage your home is likely to face.
2024 outage duration signals
| State or group | 2024 signal from EIA | Planning takeaway |
|---|---|---|
| South Carolina | Nearly 53 hours of interruptions per customer, the longest reported by EIA for 2024 | Plan for longer food, communications, and sump/load protection, not just device charging |
| North Carolina and Florida | Hurricane Helene and Milton contributed to prolonged outage impacts | Storm-season backup planning should include refrigerator/freezer and communication loads |
| Texas | Hurricane Beryl left millions of customers without power | Heat, food protection, and communications are important outage priorities |
| Arizona, South Dakota, North Dakota, Massachusetts | Less than two hours on average in 2024, according to EIA | A smaller essentials plan may be enough for many households, though local risk still matters |
Frequency vs duration
EIA describes two important reliability metrics: SAIDI, which measures total duration of non-momentary interruptions, and SAIFI, which measures how often interruptions happen. Duration matters for food, sump pumps, and medical-device backup. Frequency matters for nuisance outages, router reboots, remote work, and whether a UPS is worth owning.
How to use this data at home
If your state tends toward long storm outages, think in layers: food protection, internet, phone charging, lighting, and any household-specific risk like a sump pump or CPAP. If your state tends toward shorter but frequent interruptions, a UPS or smaller power station may solve more real-life frustration than a giant battery.

Methodology note
This page summarizes EIA's published 2024 outage analysis and reliability discussion. It does not claim to replace utility-by-utility reliability filings or a live outage map. The goal is to translate the national and state-level signals into practical household backup questions.
Press-style summary
Backup Power Report's takeaway from the EIA data is simple: 2024 was a reminder that outage planning is regional. A national average can hide the difference between a short nuisance outage and a multi-day storm disruption. Households in long-duration storm states should think about food, communications, pumps, and medical equipment before comparing brand names.
