It’s pitch black. You’re sitting in your living room in Whitlock Terrace or maybe over near the Big Chicken, and suddenly, the humming of the refrigerator just... stops. That silence is heavy. If you’ve lived in Cobb County for more than a week, you know a Marietta GA power outage isn't just a "maybe" scenario; it’s a "when" scenario. Between the massive oak trees that line our historic streets and those sudden North Georgia summer thunderstorms that roll in at 4:00 PM, the grid takes a beating.
Most people just sit there. They wait for the lights to flicker back on. They check their phone, see they have 12% battery, and start to panic slightly. But honestly, navigating a blackout in Marietta requires knowing exactly who owns the wires above your head, because in this city, that answer changes depending on which side of the street you’re standing on.
Who Actually Controls Your Electricity?
Marietta is unique. Unlike many suburbs where one giant conglomerate handles everything, we have Marietta Power and Water. It’s a community-owned utility that’s been around since 1906. If you live within the city limits, you’re likely dealing with them. However, if you’re just outside the line—say, heading toward Kennesaw or Smyrna—you’re probably an Georgia Power customer or even tied to Cobb EMC.
Why does this matter? Because their response times and reporting systems are totally different.
If you're a Marietta Power customer, you can’t just look at a statewide map and see your house. You have to call their specific dispatch. They don't always have the fancy real-time AI tracking that the multi-billion dollar corporations use. It’s more localized. It’s neighbors fixing neighbors' lines. That’s usually a good thing for speed, but it means you have to be more proactive about reporting the outage yourself instead of assuming "they already know."
The Real Culprits Behind the Darkness
It’s rarely just "the wind."
In Marietta, the biggest threat to your Netflix binge is actually the canopy. We love our trees. The city is literally famous for them. But those limbs are heavy, and when we get that red-clay-soaking rain, the ground gets soft. A healthy-looking tree can tip just enough to take out a transformer on Polk Street, and suddenly three blocks are dark.
Then there’s the wildlife. Squirrels are the unsung villains of the electrical grid. They love chewing on the insulation or accidentally bridging a gap in a substation. It’s a messy way to go for the squirrel, and a frustrating way for you to lose your AC in 95-degree heat.
- Severe Weather: Thunderstorms, ice storms (though rare, they are devastating), and high winds.
- Infrastructure Stress: During those July heatwaves, everyone’s AC is cranking. The transformers get hot. Sometimes they just give up.
- Accidents: Someone takes a turn too fast on Burnt Hickory Rd and hits a pole. It happens more than you’d think.
What to Do the Moment the Lights Go Out
Don't open the fridge. Seriously. Just don't.

Your refrigerator will keep food safe for about four hours if you leave the door shut. A full freezer can go 48 hours. Every time you peek in to see if the milk is still cold, you’re letting out the precious "cold" and inviting bacteria to the party.
First, check your breakers. It’s embarrassing to sit in the dark for three hours only to realize you just tripped a main switch because you ran the microwave and the space heater at the same time. If the whole neighborhood is dark, you’ve got a real outage.
Grab your phone and report it.
- Marietta Power: Call 770-794-5160.
- Georgia Power: Use their online portal or call 888-891-0938.
- Cobb EMC: Text "OUT" to 898-362 if you’ve registered your number.
The Hidden Danger of Portable Generators
We see this every time there’s a big storm in Georgia. Someone buys a generator at the Home Depot on Cobb Parkway, brings it home, and runs it in the garage with the door "mostly" open.
Don't do that. Carbon monoxide is a silent killer. It doesn't smell. It doesn't have a color. It will seep into your house through the vents. Generators must be at least 20 feet away from the house. No exceptions.
Also, watch out for "backfeeding." If you try to power your whole house by plugging a generator into a wall outlet, you can send electricity back out into the power lines. This can electrocute the utility workers who are trying to fix the problem. It turns a routine repair into a fatal accident.
Navigating the Tech During a Blackout
Your smartphone is your lifeline, but it's also a battery hog. The moment the power dips, flip your phone to "Low Power Mode." Turn down the brightness. If you have a tablet or a laptop, use those for your information gathering and save the phone for emergencies.
The Georgia Power Outage Map is a decent tool, even if you aren't their customer, because it shows the general "health" of the grid in the Southeast. If you see a sea of red icons across Atlanta, you know you're in for a long night. If it’s just one little blip over your street, the crews will likely get to you faster.

Preparing for the Next One (Because it’s Coming)
You don't need a bunker, but you do need a "blackout bin."
Stop relying on the flashlight feature on your phone. It drains the battery and isn't that bright. Go buy a few headlamps. They’re cheap, and they keep your hands free so you can actually do things like change a diaper or find the manual for your fuse box.
Keep a stash of external battery packs. The "Anker" brand is a gold standard for a reason—they hold a charge for months sitting in a drawer. If you have a camping stove, make sure you have fuel. There’s nothing worse than being hungry and staring at a cold stove because you have an electric range.
Essential Supplies for Marietta Residents
- Water: One gallon per person per day. If you’re on a well (rare in the city, common in rural Cobb), no power means no water pump.
- Lighting: LED lanterns are better than candles. Fire departments hate candles during outages for obvious reasons.
- Information: A battery-powered NOAA weather radio. Sometimes cell towers go down too.
- Cash: If the power is out city-wide, credit card machines at gas stations won't work.
The Mental Game of a Long-Term Outage
The first hour is a novelty. You light some candles, maybe play a board game. By hour six, when the house is getting stuffy and the kids are bored, it gets real.
In Marietta, we have "cooling centers" or "warming centers" depending on the season. Usually, the city will open up places like the Cobb County Civic Center if the outage is widespread and expected to last more than a day. Keep an eye on the Marietta City Government Facebook page or the local Twitter (X) feeds. They are surprisingly fast at updating these things.
Myths and Misconceptions
People think utility companies "prioritize the rich neighborhoods." Honestly, that's not how the grid works. They prioritize high-density areas and critical infrastructure first.
Hospitals like Wellstar Kennestone are at the top of the list. Then come police stations, fire houses, and water treatment plants. After that, they look at the "biggest bang for their buck." If fixing one substation brings 2,000 people back online, they’ll do that before they go to a cul-de-sac where a single tree took out three houses. It’s not about the property value; it’s about the engineering.
Also, just because you see a utility truck parked on your street doesn't mean they are working on your power. They might be waiting for a "tree crew" to clear the debris before they can touch the lines, or they might be communicating with a dispatcher to make sure the line is actually dead before they climb the pole.

Actionable Steps to Take Right Now
Instead of waiting for the next storm to hit, do these three things today. They take ten minutes total but will save you hours of stress later.
First, locate your utility account number and save it in your phone contacts under "Power Company." You do not want to be hunting for a paper bill in the dark.
Second, trim the damn trees. If you have branches overhanging your service line (the wire that goes from the pole to your house), that is your responsibility, not the city's. Call an arborist. Spending $300 now is cheaper than replacing your electrical mast and paying for an emergency electrician later.
Third, buy a surge protector for your expensive electronics. Not just a power strip—a real surge protector with a Joule rating of 2000 or higher. When the power comes back on, it often comes with a "spike" that can fry the motherboard on your $2,000 OLED TV.
Lastly, check on your neighbors. We have a lot of seniors in Marietta, especially in the older neighborhoods near the Square. If the AC is off for four hours in a Georgia August, that’s a medical emergency for someone in their 80s. A quick knock on the door can literally save a life.
Be prepared, stay calm, and remember that the crews are usually out there working in the same miserable weather that knocked your power out in the first place. They want the lights back on just as much as you do.
Next Steps for Safety:
- Check your local utility's outage map frequently for restoration estimates.
- Unplug sensitive electronics to prevent damage from power surges during restoration.
- Ensure your backup power sources are fully charged and accessible.
