Location: Columbus, GA Type: Financial Instritution ● Tier IV Size: 20,000 SF IT Space ● 2.4MW Critical Load
Modular data center, designed to be non-complex, free-standing and with no paralleling equipment.
The building is supplied from three 2,500kVA service transformers, each fed from two utility substations, through automatic transfer switches. Each utility service, paired with a 2,500kW generator, supplies two single module Uninterruptible Power Supply (UPS) Systems and the HVAC equipment required for cooling the respective load.
The system is unique in the fact that the UPS Systems use flywheels in lieu of batteries to store energy. The major advantages of flywheels over batteries include increased reliability (the charge state of the flywheel is always known), reduced footprint (the MEP space for this building is approximately half the usual space for similar facilities), safer (no risk of explosion) and greener technology (no batteries to dispose of).

Location: Atlanta, GA Type: Financial Instritution ● Tier IV Size: 450kW Critical Load
The data center is located on the 9th floor of a high-rise building in downtown Atlanta. The original building, constructed in the early 80’s was designed as an office building without the necessary infrastructure to support a mission critical facility. Initially BCE was commissioned to design a UPS replacement, but after a quick review of the existing electrical infrastructure it became clear that more was needed.
After careful planning and design, working closely with the owner, contractor and commissioning agent, the project was completed without interruption to the data center and with minimal inconvenience to building occupants. Two redundant UPS systems now protect the data center. Redundant closed-transition switchgear transfers the load to the new generators in case of utility failure, and provides two sources of power to the critical data center equipment.
