Restaurants, medical and dental offices, churches, small warehouses, retail centers and apartment properties are all adding standby power after recent storms.
How a commercial project comes together
- Load studyDecide what must run: refrigeration, HVAC, IT, lighting, pumps, elevators. Then measure it.
- FuelNatural gas avoids refueling. Diesel is common for large or critical loads but needs fuel management.
- Electrical serviceMany commercial buildings are three-phase. Generator and switch must match.
- Transfer equipmentSwitches sized to the service, sometimes more than one for priority loads.
- Permits and engineeringStricter code, engineered drawings and inspections.
- Maintenance programScheduled service and load testing.
Natural gas or diesel?
| Natural gas | Diesel | |
|---|---|---|
| Fuel | Utility line | On-site tank, refueling |
| Typical use | Small and mid-size commercial | Large and critical facilities |
| Upkeep | Less fuel maintenance | Fuel conditioning and tank care |

Common questions
What size generator does a small business need?
It depends on what has to stay on. A licensed electrician’s load study sets the size and whether you need three-phase.
