Yes, with one condition
Most standby generators can run on natural gas, provided your home already has (or can get) a utility gas connection. The generator draws directly from that line rather than a stored tank, which means no fuel to monitor or refill during an extended outage.
What the connection involves
An installer confirms your gas meter can support the added load the generator will draw, then runs or extends a gas line sized to the unit's BTU demand. The line is pressure-tested before the generator is connected and started.
When it's not an option
If utility natural gas service doesn't reach your property at all, natural gas isn't available regardless of generator brand or model — propane is the standard fallback in that situation.
A note on cold-climate performance
Natural gas generators can lose some rated output in very cold temperatures, since gas pressure and BTU delivery can be affected by extreme cold, particularly on longer supply runs. Installers in cold-climate regions often account for this during sizing, and may recommend a cold-weather kit for the unit itself as a separate consideration from the fuel line.
