Why Florida Needs Backup Power
Florida homeowners face an average of 3.5 power outages per year, primarily from hurricanes and tropical storms. With summer temperatures regularly exceeding 95°F, losing air conditioning during an outage isn't just uncomfortable — it can be dangerous.
Hurricane Helene (2024) left over 1.2 million Florida customers without power, some for more than a week. Power in Florida is served by Florida Power & Light (FPL), Duke Energy Florida, Tampa Electric (TECO). According to the Florida State Electricity Profile, the state averages 3.5 outages per year with a mean duration of 8.2 hours per event.

Frequently Asked Questions — Florida
Do I need hurricane-rated mounting for my generator in Florida?
In coastal high-wind zones (most of South Florida, the Gulf Coast, and the Keys), yes. The Florida Building Code requires equipment rated for 150+ mph winds. Expect $300-$500 in additional mounting hardware.
What size generator do I need for a typical Florida home?
The average Florida home is about 1,800 sq ft. For whole-house coverage including central AC, a 20-22 kW standby generator is the standard recommendation. If you have a pool pump, go 24 kW.
How long does generator permitting take in Florida?
Typically 1-2 weeks. Some South Florida counties (Miami-Dade, Broward) can take up to 3 weeks during peak season.
Should I choose natural gas or propane in Florida?
If you have a natural gas line (most suburban areas), use it — unlimited fuel supply during an outage. In rural areas or the Keys, propane with a 500-gallon tank gives you 7-10 days of backup.
Will my Florida homeowner's insurance cover a generator?
The generator is typically covered as a permanently installed home improvement. Some Florida insurers offer 1-5% premium discounts for homes with standby generators.
