Fuel decides whether your generator lasts the whole outage
A standby generator is only as good as the fuel behind it. It has to burn something for days at a stretch, because that is how long Tampa Bay outages tend to run after a Gulf storm. Around here the answer comes down to two paths: a natural gas line from the street, or an on-site propane tank in the yard. Which one you end up with is usually settled by what your property already has rather than by preference, and getting it wrong leaves you with a generator that either starves mid-outage or never clears inspection.
If you want the head-to-head on how the two fuels behave, the natural gas vs. propane guide lays that out. This page is about the setup work: what is available where you live, and what a licensed installer actually does to make the fuel side right.
Natural gas, where the main reaches your street
Where a gas main runs down your road, natural gas is the low-hassle choice. There is no tank to fill and, as long as the line stays pressurized, no running dry during a long outage. In Tampa Bay that mostly means TECO Peoples Gas, which covers a good share of Tampa and inner Hillsborough County, plus the municipal systems in St. Petersburg and Clearwater on the Pinellas side. Coverage is genuine inside the older, built-up areas and along established corridors. It thins out quickly in newer Pasco subdivisions and stretches of Pinellas, where plenty of streets simply never got a gas main.
Tapping a gas line for a generator is more involved than it sounds:
- Line sizing. A large standby unit is a big fuel consumer. A 22 kW generator at full tilt can call for somewhere in the range of 280,000 to 350,000 BTU per hour, so the pipe has to carry that on top of the furnace, water heater, range, and anything else already on the system.
- Distance matters. A long run from the meter to the generator pad often needs a larger diameter, or the unit loses pressure and starves at the far end.
- Meter capacity. A standard residential meter feeding existing gas appliances can be maxed out by adding a generator. TECO Peoples Gas or the local municipal utility may have to upsize the meter or the regulator before the system runs reliably.
That is why a natural gas hookup for a generator is a permitted job for a licensed pro, not a weekend project.
Propane, the default across Pasco and outer Pinellas
For the many homes with no gas main, propane is the standard, and in New Port Richey, Wesley Chapel, and parts of Palm Harbor that describes a lot of streets. An on-site LP tank feeds the generator and depends on neither the electric grid nor a buried gas line that a storm could disturb. You control your own supply, and the tank is full until you burn it.
The tradeoff is runtime, which is a direct function of tank size:
- A larger tank buys days of unattended running. As a rough guide, a whole-home unit at partial load can run roughly a week or more on a 500-gallon tank, which is why that size shows up so often for full-home backup.
- Smaller tanks, say 100 or 250 gallons, cost less and take less yard space, but they need a refill sooner in a long outage.
- The right size depends on the generator’s output, how much of the house it carries, and how long outages in your part of the bay tend to last.
There is a Gulf Coast wrinkle worth stating plainly: after a major storm, propane delivery trucks cannot always reach you fast. Roads flood, demand spikes, and suppliers back up. The lesson from Helene and Milton is to top the tank off before the storm hits, not after.
Placement, flood elevation, and the permit
Fuel setup is not only about the fuel. Where a tank, a meter, and the generator are allowed to sit is shaped by local rules, and in low-lying coastal Tampa Bay that means flood elevation. Equipment often has to be raised so surge cannot reach it, and tank placement carries setback requirements of its own. The flood zone generator placement guide covers the elevation side, and gas and tank work is permitted and inspected. Requirements shift by county and city, so the sizing, the placement, and the permit get worked out for your specific address rather than off a template. County-by-county specifics live in the permitting by county guide.
How fuel ties into the rest of the system
Fuel never stands alone. It has to match the generator and the switch, so it is spec’d as part of a full generator installation alongside the automatic transfer switch. On propane especially, ongoing maintenance earns its keep, since a tank that quietly runs low or a regulator that drifts will leave you dark at the worst possible moment.
