Uninterruptible Power Supplies (UPS) with battery backup are sized to carry the critical load-the essential systems (servers, networking equipment, storage) that must stay operational during a power transition.

Explanation
Uninterruptible Power Supplies (UPS) with battery backup are sized to carry the critical load-the essential systems (servers, networking equipment, storage) that must stay operational during a power transition. Generators typically take 10–30 seconds to start and reach stable voltage and frequency. During that gap, the UPS bridges the power supply. Sizing for the full HVAC, network, or fire suppression load would be inefficient and costly; only the critical IT load that cannot tolerate even momentary outages must be covered by the battery backup.
