A standby generator is a real investment, so the honest question is not “is it nice to have” but “does my household actually need one.” For some First Coast homes the answer is clearly yes. For others a portable unit or nothing at all is the smarter call. Here is how to tell where you land.
Who benefits most
Standby power earns its keep when an outage is more than an inconvenience. You are a strong candidate if any of these describe your home:
- Medical equipment at home. Oxygen concentrators, CPAP machines, powered wheelchairs, and refrigerated medication turn a multi-day outage into a health risk, not just a dark house.
- A well and septic system. Homes around Clay County, Middleburg, and rural Nassau often run on a private well. No power means no running water and no working septic pump, so the outage hits the basics of daily life.
- Elderly residents or young children. Losing air conditioning through a Florida summer is genuinely dangerous for people who do not regulate heat well.
- Working from home. If an outage means lost income, meetings dropped, or spoiled inventory, backup power pays for itself faster than the sticker suggests.
- Flood-prone or riverfront property. Homes near the St. Johns River basin, Black Creek, and the marsh around St. Augustine can lose power for days while restoration crews wait for water to recede.
The First Coast outage reality
This region does not get frequent outages so much as long ones. Hurricane Matthew in 2016 raked the coast and knocked out power across Duval, St. Johns, and Nassau. A year later Irma in 2017 drove record flooding on the St. Johns River and Black Creek, and many homes waited days for restoration while crews worked around standing water. Ian and Nicole in 2022 added more wind and rain events to the recent record. The pattern is the same each time: the grid comes back for most people within a day or two, but low-lying and rural addresses, especially those on cooperative and beach utilities, often sit at the back of the restoration line.
Different parts of the First Coast are served by different utilities, JEA in Jacksonville and Duval, FPL across St. Johns and Nassau, Clay Electric Cooperative in Clay County, and Beaches Energy in the beach towns, and each has its own restoration priorities and timelines. You can see the local storm and outage record on the power outage history page.
Standby versus portable at a glance
A quick comparison so you can weigh the two honestly:
- Standby generator: permanently installed, wired to a transfer switch, runs on natural gas or propane, and starts automatically within seconds of an outage. It can carry central AC and run for days unattended. Higher upfront cost, and think of any figure you see online as a ballpark, not a quote.
- Portable generator: far cheaper to buy, but you have to haul it out, run it outdoors well away from the house, refuel it with gasoline every several hours, and manually connect only a few circuits. It will not automatically start, and it usually cannot run central air. It also depends on gasoline being available, which is exactly what runs short after a storm.
For a household that just wants the fridge and a few lights alive during a short outage, a portable can be enough. For anyone who needs the power to come on by itself and stay on through a multi-day event, standby is the category that fits.
When you may not need one
Being honest cuts both ways. Standby power may not be worth it if your outages are short and rare, if you are comfortable riding out a day without AC, if you rent rather than own, or if you are planning to move soon and will not recoup the install. A portable unit or a good plan for a nearby shelter may serve you better and cost far less. There is no reason to buy more resilience than your situation calls for.
