Case Study - Backup Generation - Crystal Cold Storage

BACKUP GENERATOR CASE STUDY

SITUATION
Crystal Cold Storage (CCS) provides cold storage
services from its 2.5 million cubic feet facility, built
originally in 2001. Recognizing the business risk associated
with loss of power at this New England location,
CCS engaged Groom Energy to study how a backup
generation system might protect their business
during an event.

PROJECT
Groom Energy engineers analyzed CCS's facility to determine
which loads should be supported during an outage event
and what system design could accomplish this goal. To base
our design on actual operations we first metered and data
logged the building's primary loads and sub-systems for an
extended period. The comprehensive design was then
developed including the prime mover, it's concrete pad
and pilings, fuel tank, transfer switch, wiring and
interconnection plan.

RESULTS
Our final installation was based on a 500 kW Caterpillar
generator, with an outdoor primary-service rated, 4-pole
1200 amp capacity Automatic Transfer Switch (ATS) and
a custom remote relay panel for enabling and disabling
non-critical loads. The system's double-walled 1,000 gallon
fuel tank made it possible for full load operation for 24 hours
without refueling.
