Hotel BESS sizing starts with guest-critical loads, not the full building nameplate. A hotel may want silent backup for rooms, lifts, pumps, security, Wi-Fi, and selected HVAC while leaving laundry or large kitchens outside the critical backup group.
Inputs to collect
- Generator kVA and average daily runtime
- Monthly diesel spend and grid bill
- Critical load list in kW
- Backup hours required during night and guest-peak periods
- Existing solar, roof space, and electrical room constraints
Why hotels need batteries
BESS can reduce generator starts during short outages, provide silent backup for sensitive guest periods, and store solar energy for evening use. The result is lower diesel cost and better guest experience.
Next step
