Intermountain Healthcare Primary Children’s Medical Center

It was a terrific experience! And the system works! When we had a power outage, the system came online exactly the way Jeff designed it. Mike Creason, Assistant Administrator for Facilities Management, Primary Children’s Hospital

Intermountain Healthcare Primary Children’s Medical Center Essential Systems Power Study

Primary Children’s Medical Center (PCMC) is nestled against the foothills of the Wasatch Mountain Range, affording striking views of the Salt Lake Valley. The facility is designed to meet the special needs of children and their families.

Prior to design, Spectrum Engineers provided a study of the existing power systems and provided recommendations for improvements. It was important to understand the actual load on the essential power system to help ensure that the generators and distribution equipment would not be overloaded. The Spectrum Engineers and PCMC team installed temporary power metering equipment on the load side of each of the transfer switches for one week. It was found that the total essential power load was 1326 kW.

Spectrum Engineers created step-by-step procedures for the study that included start and finish times, duration, team members’ responsibilities, and descriptions of the action to be taken during the study. The system tests were performed in a functioning hospital. To avoid power interruptions during the busiest times and during scheduled surgeries, tests were typically scheduled between 12:00 a.m. and 5:00 a.m. on Sunday morning. Given the limited time for testing, it was imperative that the tests were precisely timed.

After completion of the project the annual costs of electrical energy, based on 6 months of operation, have been reduced by $750,000, due to the decommissioning of the cogeneration system.

Because of the sensitive work that goes on inside Primary Children’s Hospital, healing children and their families, there was less room for error.Jeff Richards, P.E., LEED AP, Spectrum Engineers
