IBM was looking to upgrade the power backup systems for their 100,000 square foot customer data center facility in Greece, New York. A key aspect of the upgrade would be the installation and commissioning of a new emergency power distribution system to assure the facility would remain operational in the event of a power failure.
O’Connell Electric subcontracted from Skanska USA to provide the primary components of the emergency power distribution system as well as all systems testing and commissioning services. The $750K project took six months to complete. The electrical construction work included installation of three 5KV / 2500KW standby generators, 5KV paralleling switchgear, two 34.5KV / 7.5MVA transformers, interior double ended 34.5 KV transfer switches, and the control wiring connecting paralleling switchgear to transfer switches. O’Connell retrofitted the facility’s existing electrical mains to allow for switching from normal to emergency power, and back again, without interruption.
O’Connell’s Technical Services group provided systems component testing that included relays, switchgear, transformers, and breakers and carried out all systems testing and commissioning.
