Natural Gas vs. Propane for a Home Standby Generator

Which fuel makes sense for a Louisiana home, and what each one means for cost, runtime, and storm prep.

Nearly every residential standby generator can run on either natural gas or propane. The right choice usually comes down to one question: does your home already have a natural gas line?

Natural gas

  • No tank to buy, place, or refill.
  • Can run as long as the utility keeps gas flowing — often for days.
  • Your meter may need to be upgraded to handle the extra load; your installer coordinates this with the gas utility.

Propane

  • Works anywhere, including rural homes without gas service.
  • Requires a tank sized for how long you want to run. A larger tank means longer runtime between deliveries.
  • Fill the tank before hurricane season — delivery trucks get backed up once a storm is coming.

Bottom line

If you have natural gas, use it. If you don't, propane is a solid, proven option — just plan tank size and refills ahead of storm season.
