A storm rolls through Hamilton County. The lights flicker, then the house goes dark. Most people reach for their phone before they reach for anything else. The first question is usually the same: Is EPB reporting an outage? The EPB outage map can show where service trouble has been reported and how repairs are progressing. This guide covers where to find it, what the different statuses mean, and how to report an outage if your home isn't showing up. It also covers what to do when the power stays off for hours. And one quick clarification: this guide is about EPB in Chattanooga, Tennessee, not the similarly named utilities in Kentucky.
Where to Find the EPB Outage Map and What It Shows
EPB is Chattanooga's publicly owned electric power board and a local TVA power company. It serves more than 178,000 customers across most of Hamilton County and parts of eight nearby counties in Tennessee and Georgia. The outage map is part of EPB's Outage & Storm Center. Called the Automated Grid map, it shows current service issues and their status. The MyEPB app also provides outage updates and restoration notifications.
What the outage map statuses mean
EPB uses several status labels to show what's happening with an outage and where it stands in the repair process. Knowing what each one means can give you a better idea of whether a crew has been dispatched or repairs are already underway. Here's what the main statuses mean in everyday terms:
EPB status | What it means for you |
Outage Reported | EPB has received or detected a report of lost power in the affected area. |
Crew En Route | A repair crew has been assigned and is heading to the problem. |
Repair in Progress | Crews are working on the equipment or line causing the outage. |
Service Restored | EPB has reported that power has been restored. |
The map shows affected areas, customer counts, restoration estimates, and repair progress. But it only reflects the information EPB has received. If your home is dark but the map doesn't show an outage, check your neighbors' power and your breaker panel. Nashville residents can also use a similar NES outage map. If your outage still isn't listed, report it to EPB.
How to Report an EPB Power Outage (and When to Call 911 Instead)
If the map doesn't show your outage, report it. EPB provides several ways to do that, so you can use whichever option works during the outage. Before you report anything, check your breakers and see whether nearby homes are also without power. Have your service address ready. That can make the report easier to complete.
When to call 911
A power outage is one thing. A damaged power line is another. If you see a downed line, sparks, fire, or another immediate danger, stay away and call 911. Treat every fallen power line as live. Don't walk over a wire. Don't move it with a broom or other object. Keep children and pets away from the area until emergency crews make it safe.
Ways to report an EPB electric outage
EPB gives you several ways to report an outage, so you can use the option that's most convenient during a power outage. You can report it through the app, online, by text, or by phone.
Method | What to do |
MyEPB app | Report the outage and track restoration updates from your phone. |
Text | Text OUTAGE to 423-648-1372. |
Live chat | Use EPB's online chat to reach a representative. |
Online | Report the outage through EPB's website, with or without signing in. |
Phone | Call EPB's direct outage number at 423-648-1372. |
EPB may direct online reports to chat or phone support if they can't be processed. Keep both the text and phone options handy as backups. This guide covers electric outages. EPB Fiber customers should use the separate Fiber outage option. Your phone can also help you report an outage or use the MyEPB app. These tips for keeping Wi-Fi on can help if your internet equipment has backup power. Reporting an outage doesn't guarantee immediate restoration. Damaged poles, downed trees, and other storm damage can take time to repair.
Backup Power for an EPB Outage That Lasts Longer Than Expected
EPB's automated grid can reroute power around some faults, but it can't repair a broken pole or line right away. When storm damage takes time to fix, backup power can keep essential appliances running while you wait.
Start with the refrigerator
FEMA says a refrigerator can keep food cold for about four hours during an outage. A full freezer can stay at a safe temperature for about 48 hours. A sample refrigerator using about 630 kWh per year consumes roughly 1.7 kWh per day. Based on that example, an EcoFlow DELTA 3 Max could provide about one day of refrigerator runtime after allowing for inverter losses, with no other devices connected. That's only an estimate. Check your refrigerator's EnergyGuide label for a more accurate figure. Opening the door often or running the fridge in a hot kitchen can also increase energy use.
How much runtime can you expect?
The same example refrigerator could run for about six days from the standard 12kWh EcoFlow DELTA Pro Ultra X setup after inverter losses. In a real home, other essentials will reduce that runtime.
Backup option | Example refrigerator runtime |
EcoFlow DELTA 3 Max, 2,048Wh | About 1 day |
EcoFlow DELTA Pro Ultra X, 12kWh | About 6 days |
Recharge during a longer outage
The EcoFlow DELTA 3 Max supports four charging methods and can reach 80% in about 68 minutes with wall or generator charging. If you use a fuel-powered generator, keep it outdoors and at least 20 feet from doors, windows, and other building openings. The EcoFlow DELTA Pro Ultra X is an installed backup system. Its standard setup provides 12kWh of storage and 12kW of output. It can expand up to 180kWh and 36kW, depending on the configuration. Its ability to run larger loads, such as central AC or an electric range, depends on the system setup and battery capacity. Renters will also need landlord approval. Before storm season, test your power station's runtime at home. Testing it ahead of time gives you a better idea of what your appliances will use during an outage.
For households that need more than essential backup, the EcoFlow DELTA Pro Ultra X offers a whole-home setup. For a more portable option, the EcoFlow DELTA 3 Max is designed to keep key appliances and devices running during an outage.
The two systems serve different needs. The EcoFlow DELTA 3 Max works well for renters and households that need to keep essentials like a refrigerator, phones, or a CPAP running. The EcoFlow DELTA Pro Ultra X is designed for homeowners who want selected circuits to switch to backup power automatically. If backup power seems unnecessary with EPB's automated grid, it helps to understand what the system can handle and where its limits are.
Why EPB Outages Can Look Patchy: The Automated Grid
You may have seen this during a Chattanooga storm: your house loses power, but a few houses down the street still have lights. That can happen because EPB's smart grid can reroute electricity around some problems.
Why your neighbor may still have power
EPB says its Smart Grid can reroute power during storms, isolating a problem and sending electricity through another available path. That can leave some homes without power while nearby homes stay lit. A U.S. Department of Energy profile says EPB received $111.5 million in Recovery Act funding and planned about 1,500 smart switches. A 2017 DOE and Oak Ridge National Laboratory case study reported more than 1,200 automated switches and sensors across 171 circuits, along with a 43.5% reduction in annual outage minutes since 2012. During a July 5, 2012 storm, the system restored power to 40,579 customers within one to two seconds. These figures reflect past performance and don't predict how long your next outage will last.
Where automation stops
Smart switches can reroute electricity around a damaged section. They can't repair the damaged section itself. If a tree takes down a line serving your block, a crew still has to remove the hazard and make the physical repair. That's where a home battery can bridge the gap. The larger trend toward smart grids and home batteries shows how the two technologies can complement each other. The grid can restore what it can. A battery can keep essential loads running while you wait.
What Usually Causes EPB Outages Around Chattanooga
Chattanooga gets a mix of severe weather throughout the year. The type of storm changes by season, but the basic problem is familiar: strong weather can damage the equipment that carries electricity to homes. A long-term National Weather Service Morristown severe weather study found that tornado activity in the region peaked in April, with a secondary peak in November. Large hail peaked in May. By June, damaging winds became the dominant severe weather type in the study. The study covers 1950 through 1996, so these figures describe a long-term pattern rather than a current forecast.
Chattanooga outage threats by season
Chattanooga faces different outage risks throughout the year. This seasonal breakdown shows the weather threats that can affect local power service.
Season | Common outage threats |
Spring | Tornadoes, thunderstorms, large hail, and falling trees |
Summer | Thunderstorm winds, lightning, and trees or branches on power lines |
Fall | Thunderstorms and a secondary period of tornado activity |
Winter | Ice, snow, wind, and tree damage |
Trees are a common problem after severe weather. A branch can pull down a line even when the main storm has already moved out of the area. If you see a downed line after a storm, stay away and report it. Don't assume a line is safe because there are no visible sparks. For Tennessee households, understanding how tornado risk shifts across Tennessee can also help with seasonal storm preparation.
A Chattanooga Storm Checklist Before the Next EPB Outage
A little preparation can make a long outage easier to handle. Before the next storm, charge your devices, check your backup power, and make sure you can quickly reach EPB if the lights go out.
Prepare before the storm
Charge your devices: Charge phones, laptops, and other essential electronics before severe weather arrives.
Plan for medical equipment: If anyone in your home relies on powered medical equipment, make a backup plan with your doctor.
Protect your food: Keep refrigerator and freezer doors closed during an outage to help food stay cold longer.
Use generators safely: Keep fuel-powered generators outdoors and at least 20 feet from doors, windows, and other building openings.
Keep EPB information handy
Install the MyEPB app and turn on push notifications.
Save 423-648-1372 in your phone. You can text OUTAGE to this number to report an outage.
Bookmark EPB's Outage & Storm Center, so you can check the outage map quickly.
Check your backup power
Charge your portable power station regularly instead of waiting for a storm warning.
Keep an extension cord rated for the equipment you plan to run.
If you have an installed backup system, know which circuits it can power.
For a more complete setup, this power outage supply kit covers essentials such as water, flashlights, and first-aid supplies.
Conclusion
The EPB outage map gives Chattanooga residents a quick way to see where power problems have been reported and how repairs are progressing. If your outage isn't listed, you can report it through the MyEPB app, text, chat, online form, or phone. For longer outages, plan around the loads that matter most. An EcoFlow DELTA 3 Max can cover essential devices in a portable setup, while the EcoFlow DELTA Pro Ultra X provides a larger installed backup option for selected home circuits. The easiest time to make that plan is before the next storm, not after the lights go out.
FAQs
How do I check if EPB has a power outage in my area?
Go to EPB's Outage & Storm Center and open the Automated Grid outage map. You can also check the MyEPB app for outage updates. If your home isn't listed, check your breaker panel and see whether nearby homes have power. If needed, report the outage through EPB.
What is the EPB outage phone number?
EPB lists 423-648-1372 as its direct outage number. You can also text OUTAGE to the same number to report an electric outage. If you see a downed or sparking power line, don't approach it. Move away from the area and call 911 if there is an immediate safety emergency.
Why is my power out when my neighbors have power?
EPB's automated grid can reroute electricity around some faults. That can leave one street, block, or group of homes without power while nearby customers still have service. Your own breaker could also be the issue. If your neighbors have power and your home doesn't, check the breaker panel before reporting an EPB outage.
Can I get EPB outage alerts on my phone?
Yes. The MyEPB app can provide outage information and push notifications with restoration updates. Set up notifications before storm season so you don't have to configure the app during an outage.
How long can a portable power station run my fridge during an EPB outage?
It depends on the refrigerator and battery. A refrigerator using about 1.7 kWh per day could run for roughly one day on an EcoFlow DELTA 3 Max, assuming it's the only load. Actual runtime will vary. Check your refrigerator's EnergyGuide label for a more accurate estimate.
