Florida hurricane preparation

Backup power before the storm, not during it.

Atlantic hurricane season runs June 1 through November 30. The people who come through long outages comfortably are the ones who worked this out months earlier.

Plan your backup power

The week a storm is named is the worst week to buy.

Every Florida hurricane season follows the same pattern. A storm enters the Gulf or comes up the Atlantic coast, and suddenly everyone wants a generator on the same day. Good units are gone. Transport is competing with evacuation traffic. Licensed electricians are fully booked. Fuel stations run dry. Whatever is still available is not necessarily the right size for your building, and there is no time to find out.

Buying in the off season means you actually get to choose. You can size properly, inspect the unit, arrange installation on a normal schedule, and test it before you need it.

Decide what has to stay running.

For a home, that usually means refrigeration, at least some air conditioning, well pump if you are on a well, lights, internet, and medical equipment if anyone depends on it. Air conditioning is the load people are most tempted to leave out and most regret leaving out — a sealed Florida house in August without cooling becomes unusable quickly.

For a business, the list is different: refrigeration and cold storage, point of sale and network equipment, security and access control, sump or lift pumps, and whatever production equipment cannot sit idle. A business that stays open when the surrounding area is dark is often the one that keeps its customers. See the sizing guide for how those loads turn into a generator size.

The connection matters as much as the generator.

A generator is only half the system. The other half is how it connects. An automatic transfer switch senses the outage, starts the generator, and moves the load over without anyone present — which matters if the storm hits while you are away or asleep. A manual transfer switch or interlock costs less and requires someone to operate it.

What is never acceptable is back-feeding: running a cord from a generator into an outlet or dryer receptacle to energize house wiring. It sends power backward through your meter onto utility lines that crews believe are dead. People are killed this way. Have a licensed electrician install a proper transfer switch.

Fuel is the part people underestimate.

A generator with four hours of fuel is not a hurricane plan. Florida outages after major storms have run for days in some areas. Work out your expected hourly burn, multiply by the days you want to cover, and decide now where that fuel is stored and how it is legally and safely kept.

Stored diesel is not indefinite. It needs stabilizer and biocide treatment, and it needs to be turned over rather than sat on for years, or you end up with contaminated fuel and plugged filters on the one night the generator has to work. Arrange a refueling source in advance as well, because the queue at the local station during an outage is not a supply plan.

Placement and safety.

The generator goes outdoors, on stable ground, with the exhaust directed away from any door, window, or air intake. Engine exhaust contains carbon monoxide, and carbon monoxide poisoning kills people after Florida storms every single year. Give the unit clearance for cooling airflow and for service access, and think about storm surge and flooding when choosing the spot — a generator sitting in water is no use to anyone.

Test it before the season.

A standby generator that has never been exercised is an assumption, not a backup plan. Run it under load periodically, keep the batteries healthy, keep oil and filters current, and confirm the transfer switch actually transfers. The failures that show up during a hurricane are almost always the ones that could have shown up in April.

Talk to someone who has worked on these.

GTG Power’s owner has spent 30 years repairing and selling generators. That means the conversation covers what actually fails, what a unit’s hours and history really tell you, and what size genuinely fits your building — not just what is in stock. We confirm the specification, condition, and price, and arrange delivery anywhere in Florida.

Hurricane backup power questions

When should I buy a generator for hurricane season?

Well before it starts. Atlantic hurricane season runs June 1 through November 30. Once a storm is named and heading for Florida, availability tightens, transport gets difficult, electricians are booked, and fuel lines form. Buying in the winter or early spring means you choose the right unit instead of whatever is left.

Can I connect a generator to my house myself?

No. A generator must be connected through a proper transfer switch or interlock installed by a licensed electrician. Plugging a generator into an outlet to energize house wiring pushes power backward onto the utility lines, which can kill a lineman working to restore your service, and it can destroy your equipment when power returns. This is not a corner to cut.

Do I need a permit for a standby generator in Florida?

Permanent standby installations generally require permits and inspection, and requirements vary by county and municipality. Wind load, mounting, fuel storage, and clearances all come into it in Florida. Your licensed electrician or installer will know the local rules. Portable and trailer-mounted units used temporarily are treated differently, but the electrical connection still has to be done correctly.

How much fuel should I keep on hand?

Plan for how long you actually need to run, not for one night. As a rough figure a diesel genset burns around 0.07 gallons per hour per kW produced, so a 30 kW unit at moderate load might run in the range of one to two gallons per hour. Extended Florida outages have run for days. Also plan where that fuel will be stored safely and legally, and remember that stored diesel needs treatment and periodic turnover so it does not degrade or grow contamination.

Why diesel instead of gasoline or propane?

Diesel gensets are built for sustained load and long service life, which is what a multi-day outage demands. Diesel also stores more safely than gasoline. The tradeoffs are cost, weight, and the fact that stored fuel needs maintenance. For homes, propane standby units are also common. For commercial and industrial loads that must carry real capacity for days, diesel is usually the practical answer.

Can a generator run my air conditioning?

Yes, if it is sized for it. Air conditioning is usually the single largest load in a Florida building and it has a substantial starting surge. In a hot, humid multi-day outage, cooling is often the difference between a livable building and an evacuated one, so it is worth sizing for rather than leaving out.

Where does the generator need to sit?

Outdoors, always, on a stable pad or surface, positioned so exhaust cannot reach doors, windows, or air intakes. Engine exhaust contains carbon monoxide and it kills people every hurricane season. It also needs clearance for airflow and service access, and in Florida it should be placed with flooding and storm surge in mind.
