Commercial Kitchen Backup Power and Generators: A Guide
A power outage can mean thousands of dollars in spoiled inventory and lost service hours for a restaurant, which is why many operators invest in backup power systems for at least critical refrigeration.
Sizing a Backup Generator
Generator sizing depends on which equipment needs to stay powered during an outage, with many operators prioritizing refrigeration and freezers over full kitchen operation.
- Calculate wattage needs for critical equipment only
- Prioritize refrigeration and freezer units first
- Consider partial vs. full kitchen backup capacity
- Account for startup surge wattage on compressors
Portable vs. Standby Generators
Portable generators offer lower upfront cost and flexibility, while standby generators automatically activate during an outage without requiring manual setup.
Generator Maintenance and Testing
Generators that sit unused for months can fail exactly when needed most, making periodic test runs an essential part of backup power reliability.
Portable vs. Standby Generators
| Factor | Portable | Standby |
|---|---|---|
| Upfront cost | Lower | Higher |
| Activation | Manual setup required | Automatic |
| Fuel source | Gasoline or propane | Often natural gas or propane |
| Best for | Occasional short outages | Frequent or extended outages |
