Dollar General, a Fortune 200 company headquartered in Goodlettsville, TN, needed to expand their corporate data center’s critical infrastructure and improve its reliability. Puckett Engineering evaluated the feasibility and cost to expand the data center’s emergency power and UPS systems. The study also included a detailed evaluation of using a 2N redundant electrical system. Puckett Engineering then designed and oversaw the implementation of the following improvements: replaced the emergency generator and doubled emergency power capacity, expanded UPS capacity, provided redundant power to loads, made provisions for future computer room A/C units to maintain N+1 redundancy, reduced harmonics, and added new sprinkler systems.
