Power Outages by State
Power outage risk is local, but state-level data can still help you choose a smarter backup plan. The key is separating long-duration states from frequent-interruption states.
How to read state outage data
EIA uses reliability metrics such as SAIDI and SAIFI. SAIDI is about total duration. SAIFI is about frequency. A household backup plan should ask which problem is more likely for your area: long outages, repeated short outages, or rare but severe storm events.
State planning examples from 2024
| Outage pattern | Examples highlighted by EIA | Planning direction |
|---|---|---|
| Long storm-driven duration | South Carolina, North Carolina, Florida, Texas | Food protection, internet, phones, medical loads, and possibly generator/battery systems |
| More frequent interruptions | Hawaii, Maine, Vermont | UPS for networking gear, small battery backup, and routine testing |
| Lower average interruption burden in 2024 | Arizona, South Dakota, North Dakota, Massachusetts | Smaller essentials backup may be enough for many homes |
Turn state risk into a household plan
State data cannot tell you whether your basement floods or your block has old overhead lines. Use it as a starting point, then add your home-specific loads: refrigerator, freezer, sump pump, CPAP, router, phone charging, medical equipment, and any critical home office equipment.

Three state-risk buckets
| Bucket | Typical concern | Backup power emphasis |
|---|---|---|
| Storm-duration states | Longer outages after hurricanes, ice, wind, or flooding | Food, internet, phones, freezer, medical loads, and maybe generator options |
| Frequent-interruption states | Repeated shorter outages or utility disruptions | UPS, modem/router backup, surge protection, and small batteries |
| Lower-average states | Fewer or shorter interruptions in a given year | Targeted essentials backup rather than whole-home systems |
How to build a household outage profile
- Look at your state and local utility history.
- List loads that create damage or health risk: sump pump, medical gear, refrigerator, freezer.
- List comfort and communication loads: router, phones, lights, laptop.
- Decide whether you need automatic backup or manual backup is acceptable.
- Choose the smallest system that covers the critical loads with reserve.
Why this is not a live utility outage map
A utility's live outage map is still the right place to check an active outage. Backup Power Report focuses on the planning side: what to power, how long to plan for, and when a battery, generator, or installed system makes sense before the next outage happens.
