Case Study: Primary Children's Hospital achieves hands-free 24/7 emergency standby power with Cummins

Primary Children's Hospital - Customer Case Study

Primary Children’s Hospital (Primary Children’s Medical Center of Intermountain Healthcare) in Salt Lake City needed a reliable, hands-free emergency standby power system that could support critical care 24/7 and expand capacity for much of the facility during outages. The hospital also faced aging cogeneration equipment, rising operating costs, limited power output, and compatibility issues when trying to integrate a Caterpillar generator into the existing system. Cummins provided the PowerCommand DMC 300 paralleling system along with new generator sets to address these challenges.

Cummins implemented a solution centered on one DQGAB 1500 kW generator set and two DQGAA 1250 kW generator sets, integrated with the DMC 300 Digital Master Control and transfer switches. To overcome generator pitch incompatibility, Cummins added an automatic disconnect switch to prevent damaging circulating currents, while also solving tight-space installation constraints and keeping the hospital powered during changeovers with rental generation support. The result was a fully automated, reliable standby system capable of powering 90% to 100% of the facility, with utility paralleling, improved redundancy, and strong ongoing support from Cummins.
