The recently upgraded power system at Rex Hospital in Raleigh, N.C., was designed to ensure seamless delivery of normal and emergency power to the 660-bed facility. The hospital’s design team envisioned a fail-safe emergency power system that would serve the facility’s electrical power needs for the next 30 years, according to an article on the Consulting-Specifying Engineer website.
A team led by Mike Raynor, director of facility and construction services, designed the modernized system to provide the hospital with an emergency power system with more capacity, reliability, redundancy and flexibility than the mid-1980s system it replaced.
Rex Hospital’s emergency power system upgrade included replacing three 1.25 MW generators with two new 4,160-V, 1,800 rpm, 3.0 MW units. An existing 2.25 MW generator that matches the operating voltage of the new units was retained. The generators are capable of paralleling with each other as well as with the utility source, the article said.
