When Power Fails, Patient Care Is at Risk

Healthcare facilities depend on continuous power to support life-saving equipment, clinical environments, and critical building systems. Even brief outages can disrupt patient care, compromise safety, and impact facility operations.

That’s why hospitals and healthcare organizations rely on standby power systems engineered for reliability, fast response, and long-term performance – backed by service support they can depend on.

Healthcare Power Challenges We Address:

 

Critical Load Continuity Complex Facility Requirements Operational Confidence
  • Life‑support systems, imaging, data, and environmental controls
  • Fast response to restore power during utility outages
  • Multiple buildings, phased expansions, and varying load profiles
  • Integration with existing electrical infrastructure
  • Routine testing, maintenance, and long‑term reliability
  • Support teams that understand healthcare environments

See What Healthcare Facilities We Power:

  • Hospitals
  • Ambulatory Surgical Centers
  • Blood Banks
  • Nursing Homes
  • Surgical Clinics
  • Urgent Care Centers
  • Rehabilitation Centers
  • Clinics and Medical Offices

FAQs

A: Yes. Hospitals are widely required to have emergency and standby power systems to help maintain patient safety during power outages. Hospital backup generator solutions by Cat are commonly specified to support critical healthcare functions such as life‑safety systems, medical equipment, lighting, and HVAC when utility power is unavailable. Caterpillar designs generator systems for hospitals to align with widely adopted standards used in healthcare facility power planning.

A: Hospital generators can operate for extended periods of time during an outage, depending on factors such as fuel storage capacity, load demand, and maintenance planning. Hospital generator systems are designed by Cat to support prolonged outages when paired with proper fuel management strategies. Many healthcare facilities also integrate multiple Cat generator sets or support systems to maintain continuous operation during long‑duration power events.

A: Hospital generator size varies based on facility size, critical load requirements, and redundancy planning. Generators used in healthcare range from smaller standby units supporting essential loads to large multi‑megawatt generator systems that power entire hospital campuses. Generator sizing is typically based on life‑safety systems, patient care areas, medical equipment, and future expansion needs.  

A: A hospital generator works as part of an integrated emergency power system. When utility power is lost, the system detects the outage and automatically starts the generator. Cat standby generators then supply power to critical circuits through transfer switches and switchgear, helping maintain operation of life‑safety systems and essential medical services. 

A: Yes. Hospitals rely on Cat backup generator systems to help protect patient safety and maintain essential services during power outages. Caterpillar's healthcare power solutions are designed to support emergency and standby power requirements commonly referenced by codes such as NFPA 110 and the National Electrical Code (NEC), which are widely used in hospital generator system design.

Regulation and Compliance

NFPA 110 requires monthly testing of gensets under load conditions. Gensets should run for at least 30 minutes at a minimum of 30% of their nameplate rating. If they do not achieve this load, a load bank test is necessary. Your local Cat® dealer can assist with these tests.

OSF St. Francis Medical Center Relies on Cat Backup Generators for 24/7 Patient Care

When a blown transformer resulted in an emergency power loss at OSF St. Francis Medical Center, three Cat 32 generator sets powered the 10-building campus until the utility feed was restored, more than a month later. If the center experiences an outage, the Cat generators start up within 10 seconds to provide campus-wide power.

Cat Diesel Generators Keep Hospital Running During Hurricane Ida

Louisiana Cat helped ensure Children’s Hospital New Orleans had sufficient backup power with the addition of four new Cat C32 generator sets and upgrades to two of the hospital’s existing four 3508 generator sets. To avoid any disruption to surgeries and services, the hospital switched over to its backup diesel generator sets prior to Hurricane Ida and maintained uninterrupted power before and after the storm.
