Hurricane country
Why South Louisiana runs on standby power
South Louisiana doesn’t lose power the way the rest of the country loses power. When a major hurricane crosses the coast, the grid doesn’t flicker — it goes down for days or weeks, in brutal August heat, across whole parishes at once.
It isn’t only the headline storms. Louisiana consistently ranks among the worst states in the nation for the number of hours the average customer spends without power, and Entergy’s transmission and distribution network has drawn repeated scrutiny after Hurricane Laura in 2020, Ida in 2021, and Francine in 2024.
For a home on a well pump, a medical device, or simply a refrigerator full of food and a family trying to sleep in the heat, “a few days” without power isn’t an inconvenience — it’s a crisis. A permanently installed standby generator changes that math: it detects the outage and restores power automatically, usually within seconds, and runs for as long as the storm keeps the grid down. No cords, no gas-station lines, no hauling a portable unit through the rain.
Ida came ashore at Port Fourchon as a Category 4 with 150 mph winds. It knocked out every transmission line feeding New Orleans and toppled a steel tower into the Mississippi River. More than a million Entergy customers lost power — and in the hardest-hit parishes like Terrebonne and Lafourche, restoration took weeks, not days.

The process
How a standby generator gets installed
A professional standby install is a permitted electrical and gas project — not a weekend DIY. Here’s what it looks like with a vetted local installer.
- 01
In-home assessment & sizing
The installer surveys your electrical panel, the circuits you want to keep alive, and your fuel options — then sizes the unit to your actual home, not a rule of thumb.
- 02
Permits & site prep
They pull the parish electrical and gas permits, confirm setbacks, and — critically in South Louisiana — set the generator on a pad elevated above your flood elevation.
- 03
Installation & fuel hookup
The generator is placed, wired to an automatic transfer switch at your panel, and connected to your natural-gas line or propane tank by licensed pros.
- 04
Startup, testing & inspection
The system is commissioned, tested under load, set to self-exercise weekly, and signed off by the parish inspector. Then it waits, ready, for the next outage.
Fuel
Natural gas or propane?
Standby generators here run on one of two fuels. Both are reliable — the right choice depends on what’s already at your home.
Natural gas
Lowest hassle · no refills
- Fueled straight from your utility gas line — no tank to refill and nothing to run out during a long outage.
- The generator draws fuel on demand; you never schedule a delivery.
- Best when you already have gas service — common in New Orleans, Baton Rouge, and the larger towns.
- Trade-off: slightly less output than propane for the same engine, and it relies on the gas utility’s line pressure holding.
Propane (LP)
Independent · stored on-site
- Fueled from an on-site tank (above- or below-ground), independent of the natural-gas grid.
- Higher energy content — often a bit more power than the same generator on natural gas.
- Best for homes without a gas line, rural Acadiana and bayou-country properties, or owners who want fuel on their own land.
- Trade-off: the tank holds a finite supply, so size it for multi-day runtime and plan a refill for the longest outages.
Sizing
What size generator do you need?
Standby generators are rated in kilowatts (kW). Bigger isn’t automatically better — the right size covers what you actually need to run without paying for capacity you’ll never use. Your installer calculates this from your panel, but here’s the lay of the land.
14–18 kW
Managed essentials
Keeps the critical circuits alive — refrigerator, well pump, a zone of AC, lights, internet, and medical equipment — using smart load management to run more house off a smaller unit.
22–26 kW
Whole-home
Most popular here
The most popular choice for South Louisiana homes: runs central air conditioning plus the rest of the house, so the August heat never becomes the emergency.
27 kW +
Large & liquid-cooled
For larger homes, multiple AC systems, or properties that need everything on at once — liquid-cooled engines built to run for days at a stretch.
In our climate, air conditioning is the deciding factor. Sizing has to account for the surge when your compressor kicks on — which is why a proper load calculation, not a rule of thumb, is what keeps your generator from tripping in the middle of a storm.
Permitting
Permitting in South Louisiana, briefly
Every standby install needs permits, and the rules differ by parish — which is exactly why you want a local installer who pulls them every week.
Electrical & gas permits
Nearly every parish requires a permit for the transfer switch and panel work, plus a separate gas/mechanical permit for the fuel connection.
Flood elevation
The South Louisiana difference: in flood-prone areas the unit must sit on a pad above the Base Flood Elevation. A generator that floods is a generator that fails when you need it.
Setbacks & clearances
Code (NFPA 37) and manufacturers require minimum distances from windows, doors, and combustible walls. Correct placement is part of passing inspection.
Licensed pros & HOAs
Many parishes require licensed electrical and gas work, and plenty of neighborhoods add HOA approval and screening rules on top.

Standby generator FAQ
How long can a standby generator run during a hurricane outage?
On natural gas, effectively as long as the outage lasts — it draws fuel from the utility line, so there’s nothing to refill. On propane, runtime depends on tank size; sized correctly, a tank carries a home through a multi-day outage, with a refill planned only for the longest events. Either way it runs automatically, day and night, with no involvement from you.
Will it power my whole house, including the AC?
Yes — that’s what whole-home sizing (around 22–26 kW for most South Louisiana homes) is for. Smaller managed systems keep your essentials plus a zone of AC running by intelligently shedding load. In our heat, keeping the air conditioning on is the whole point, so it’s central to the sizing conversation.
Natural gas or propane — which should I choose?
If you already have a natural-gas line, it’s usually the simplest: no tank and no refills. If you don’t have gas service, or you’d rather store fuel on your own property (common in rural Acadiana and the bayou parishes), propane is the answer. Your installer will walk through both based on what’s already at your home.
Do I need a permit, and what about flood zones?
Yes. Standby installs require parish electrical and gas/mechanical permits, and in flood-prone areas the unit must be elevated above the Base Flood Elevation. A local installer handles the permits and the elevation as part of the job — it’s a big reason to use someone who pulls these permits every week.
How much does a standby generator cost in South Louisiana?
It varies with the size of the unit, your fuel, and how much electrical and gas work your home needs — which is why we don’t quote a single number. The honest way to get an accurate figure is a free in-home assessment, and that’s exactly what we connect you with.
Do you install the generators yourselves?
No, and we’re upfront about it. Bayou Generators is a South Louisiana resource that connects you with one vetted, licensed local installer. We’re not a contractor and we don’t run a call-center list — your request goes to a single trusted local pro.
