Hurricane country, quietly

The First Coast is not as sheltered as it used to think

Jacksonville spent decades believing the bend in the coastline protected it. Two storms, one year apart, ended that idea, and the low St. Johns River basin means the water can come from the river as easily as from the ocean.

Hurricane Matthew scraped the coast in 2016 and knocked out power to a large share of Northeast Florida. Then Hurricane Irma arrived in 2017 and pushed the St. Johns River to record levels, flooding downtown Jacksonville and San Marco while hundreds of thousands of homes sat dark in the heat. Hurricanes Ian and Nicole added more outages in 2022.

It is not only the named storms. Summer thunderstorms, lightning, and the sheer age of parts of the grid mean shorter outages happen all season. For a house on a well pump, a medical device, or just a family trying to sleep in August, a permanently installed standby generator changes the math: it senses the outage and restores power on its own, usually within seconds, and keeps running until the utility is back.

Hurricane Irma · September 2017
Irma drove the St. Johns River to its highest level in decades, flooding downtown Jacksonville and riverside neighborhoods well after the winds had passed. Hundreds of thousands of JEA customers lost power, some for the better part of a week, and the storm retired the idea that Jacksonville was quietly hurricane-proof.

The process

How a standby generator gets installed

A standby install is a permitted electrical and gas project, not a weekend DIY. Here is what it looks like with a vetted local installer.

  1. 01

    In-home assessment and load sizing

    The installer walks your panel, asks what you actually want to keep running, and checks your fuel options, then sizes the unit to your home instead of guessing from square footage.

  2. 02

    Permits and site prep

    They pull the electrical and gas permits (through the City of Jacksonville or your county), confirm clearances, and set a pad. On low or riverfront lots that pad is elevated above the flood level.

  3. 03

    Set, wire, and fuel

    The generator is placed, wired to an automatic transfer switch at your panel, and tied into natural gas or a propane tank by licensed electricians and gas fitters.

  4. 04

    Startup, load test, and inspection

    The unit is commissioned, tested under real load, set to run a short weekly self-test, and signed off by the inspector. After that it just waits for the next outage.

Sizing

What size generator do you need?

Standby units are rated in kilowatts. Bigger is not automatically better: the right size covers what you actually need to run without paying for capacity you will never use. Your installer runs the real calculation, but here is the lay of the land.

14 to 18 kW

Essentials, managed

Keeps the circuits that matter alive: refrigerator, well pump, internet, a bedroom AC zone, and medical equipment. Smart load management runs more house off a smaller, cheaper unit.

20 to 26 kW

Whole-home

Most common here

The typical First Coast pick: enough to carry central air conditioning plus the rest of the house, so a September outage in the heat and humidity never turns into an emergency.

27 kW and up

Large and liquid-cooled

For bigger homes, two AC systems, or anyone who wants everything on at once. Liquid-cooled engines are built to run for days without a break.

In our climate, the air conditioner drives the number. Sizing has to allow for the surge when the compressor starts, which is why a real load calculation beats a rule of thumb, and why you can start with our sizing calculator.

Utilities and fuel

Who powers your home, and what fuels the backup

The First Coast is a patchwork of utilities, and that patchwork decides whether natural gas is even an option at your address. It is the first thing a good installer checks.

JEA

City-owned, Duval County

Jacksonville proper is served by JEA, one of the largest municipal utilities in the country. It also pipes natural gas across much of Duval, so many Jacksonville homes can run standby power straight off the gas line.

FPL and Clay Electric

The counties

Florida Power and Light covers most of St. Johns County, including St. Augustine and Nocatee, plus mainland Nassau. Clay Electric Cooperative, a member-owned co-op, serves Orange Park, Fleming Island, and Middleburg. Propane is common in both.

Beaches Energy and FPU

The coast

The Beaches and Ponte Vedra run on municipal Beaches Energy Services, not JEA. Amelia Island runs on Florida Public Utilities, which supplies both electricity and natural gas in Fernandina. Coastal wiring, coastal rules.

Short version: natural gas means no tank and no refills, but it depends on a gas line reaching your street. Propane is stored on your own property and works anywhere, but the tank holds a finite supply, so it gets sized for multi-day runtime. Compare the two fuels →

Permitting

Permitting on the First Coast, briefly

Every standby install needs permits, and the rules shift the moment you cross a county line, which is exactly why you want an installer who pulls them here every week.

City vs. county permits

Jacksonville is a consolidated city-county, so Duval permits go through the City of Jacksonville. St. Johns, Clay, and Nassau each permit through their own building departments, with their own fees and timelines.

Flood elevation

The St. Johns River basin and the low coastal lots mean a lot of the First Coast sits in a FEMA flood zone. In those areas the generator has to be set on a pad above the base flood elevation so a surge or river flood cannot drown it.

Wind anchoring

Florida Building Code requires the unit be anchored for the local design wind speed, roughly 130 to 140 mph near the coast. Correct pad and mounting details are part of passing inspection.

Licensed work and HOAs

The electrical and gas connections must be done by licensed trades, and many First Coast neighborhoods and beach communities add HOA placement and screening rules on top of code.

Standby generator FAQ

How long can a standby generator run during a hurricane outage?

On natural gas it runs as long as the outage lasts, since it draws from the utility line with nothing to refill. On propane, runtime depends on tank size, but a properly sized tank carries a home through a multi-day outage, with a refill planned only for the longest events. Either way it starts and runs on its own, day and night.

Will it power my whole house, including the AC?

Yes, that is what whole-home sizing (around 20 to 26 kW for most First Coast homes) is for. Smaller managed systems keep your essentials plus a zone of AC running by shedding load intelligently. In our heat and humidity, keeping the air conditioning on is usually the whole point of the project.

Natural gas or propane on the First Coast?

If you have a JEA or utility gas line, natural gas is usually simplest: no tank, no refills. Large parts of St. Johns, Clay, and Nassau counties do not have gas service, so propane from an on-site tank is the standard there. Your installer will tell you which is actually available at your address.

Do I need a permit, and what about flood zones?

Yes. A standby install needs electrical and gas or mechanical permits through the City of Jacksonville or your county building department. On riverfront and low-lying lots the unit also has to be elevated above the base flood elevation. A local installer handles the permit and the elevation as part of the job.

How much does a standby generator cost in Jacksonville?

It depends on the size of the unit, your fuel, and how much electrical and gas work your home needs, which is why we do not quote a flat number. Most whole-home installs on the First Coast land in a broad ballpark, and a free in-home assessment is the honest way to get an exact figure. That is what we connect you with.

Do you install the generators yourselves?

No, and we are upfront about that. River City Generators is a First Coast resource that connects you with one vetted, licensed local installer. We are not a contractor and we do not run a call-center list, so your request goes to a single trusted local pro.
