For South Louisiana homeowners, this is the only question that really matters: when a hurricane comes ashore and the grid goes down, will the generator actually run? The short answer is yes, a properly installed standby generator is designed to ride out exactly that event, automatically, with no one home and no one touching it. But “properly installed” is doing real work in that sentence, so let’s unpack what makes the difference between a generator that carries your home through the storm and one that doesn’t.
Yes, and here’s why it’s automatic
A standby generator isn’t something you start when the storm arrives. It’s already armed. Its automatic transfer switch is watching the grid around the clock, and the moment a downed line kills your power, landfall day, three in the morning, whenever, the switch starts the engine and moves your house onto generator power within seconds. Then it simply runs, for as long as the outage lasts, and hands you back to the utility when power returns. You don’t have to be awake, home, or even in the parish. If you’ve evacuated, the house keeps its power anyway: the refrigerator stays cold, the sump keeps pumping, the AC holds off the mold. That “set it and forget it” behavior is the entire reason a standby beats every alternative in a hurricane. For the full mechanics, see how a standby generator works.
”Properly installed” is the catch
A standby generator survives a hurricane because it was installed to survive one. The details that make that true are exactly the ones a rushed or unlicensed job skips:
- Permitted and inspected. Every parish requires electrical and gas permits and an inspection. That inspection is what confirms the transfer switch is wired to code and the fuel line is sound, the things that have to hold when the weather turns violent.
- On a pad, elevated above flood risk. In much of flood-prone South Louisiana, the unit is set on a pad above the Base Flood Elevation. This is the single most important storm detail: a generator sitting too low is the one appliance a storm surge will take out precisely when you need it. In New Orleans and other low-lying parishes, elevation isn’t optional.
- Correct clearances. NFPA 37 spacing from windows, doors, and combustibles keeps the unit running safely and legally, and out of the way of debris and water where it matters.
Get those right and the generator is engineered to keep running through wind and rain in its weatherproof enclosure. Get them wrong and you’ve bought an expensive lawn ornament that quits mid-storm. This is why the quality of the install, not the brand on the box, is what we push homeowners to focus on.
Fuel planning before the storm
The one thing to handle before landfall is fuel, and what you do depends on how yours is supplied:
- Natural gas usually keeps flowing straight through a hurricane. The gas network is underground, separate from the overhead power lines the wind tears down, so homes running off the utility gas line typically have continuous fuel for as long as the outage lasts, nothing to top off, nothing to ration.
- Propane runs off your on-site tank, so top it off when a storm enters the Gulf, not after it hits. Fill it while trucks can still deliver and roads are open. How long a full tank lasts is a sizing question worth understanding ahead of time, see how long a standby generator will run, so you enter the season with a tank sized for a multi-day event, not a one-day blip.
Either way, the prep is minimal and done in advance. Compare that to a portable, where “fuel planning” means hunting for gas cans during an evacuation and refueling every few hours all night long.
Why permanent beats portable in a hurricane
A portable generator can keep a fridge and a few fans alive, and for a short outage that may be enough. But in an actual hurricane it asks the impossible of you: haul it outside and start it in the wind and rain, string extension cords, refuel it through the night, and keep it far enough from the house to avoid deadly carbon monoxide, all while it can’t safely run your central AC or your hardwired circuits. And if you’ve evacuated, it does nothing at all. A permanent standby sidesteps every one of those problems. It’s wired in, weatherproofed, elevated, and automatic. In the multi-day outages this region actually gets, that’s not a marginal upgrade, it’s the difference between a house that stays livable and one that doesn’t. If you’re still weighing the two, do I need a standby generator? walks through it.
The South Louisiana track record
This isn’t theoretical here. Hurricane Ida in 2021 collapsed a major Entergy transmission tower into the Mississippi River and took down all the lines feeding New Orleans at once, the city went dark on landfall day, in dangerous late-summer heat, with restoration measured in a week or more. Lake Charles absorbed repeated hurricane strikes in back-to-back seasons. Houma and the bayou parishes have sat through some of the longest outages in the state. Our power outage history traces the whole pattern. In every one of those events, the homes that stayed powered were the ones with a permanent standby system, installed correctly, running on its own while the grid was down for days. That’s the outcome a standby generator is built to deliver, and the one we help you plan for.
