Natural gas is the preferred fuel for residential, light-commercial, and gaseous-only industrial standby applications below ~600 kW. Utility-supplied gas eliminates on-site fuel storage, simplifies AHJ approval (no UL 142 tank), and keeps PM intervals long under standby duty. Capacity is constrained by utility supply pressure (typically 5–14" WC residential, up to 5 PSI commercial) and by the engine's published BTU/hr at full load. Below are gaseous standby models in our service portfolio with manufacturer specs and field notes.
