Intermountain Medical Center Power Outage: What Happened and Who Was Affected

A power failure struck Intermountain Medical Center in Murray, Utah, at about 11:15 a.m. on August 14, 2025. Full power returned near 1 p.m. Eleven high-risk maternity and NICU patients were transferred, ambulances were diverted, and elective care was delayed. No patient harm was reported; the root cause remained undetermined after extensive testing.

The Intermountain Medical Center Power Outage showed how a loss of electricity can affect far more than lighting and basic operations. The incident tested emergency procedures, patient-care priorities, and coordination between healthcare teams and regional partners. This article reviews what happened, how the hospital responded, and the preparedness lessons that can help reduce the impact of future outages.

What Happened at Intermountain Medical Center?

Normal electrical service failed at Intermountain Medical Center in Murray at approximately 11:15 a.m. on August 14, 2025. Backup generators initially engaged, but hospital leaders later reported that generator power was also lost. Parts of the campus experienced either no electricity or limited emergency power for about 30 minutes.

The outage affected multiple buildings across the medical campus. Critical areas received priority support, while some common areas and outpatient operations were disrupted. Hospital teams worked to protect more than 500 patients, maintain essential services, and coordinate additional support while electrical systems were being restored.

Full utility power returned at roughly 1 p.m. the same day. During the disruption, the hospital temporarily diverted incoming ambulances, transferred several high-risk maternity and NICU patients as a precaution, and delayed some nonurgent procedures until systems were verified.

How Did the Outage Affect Patient Care?

Hospital leaders triaged the disruption around immediate clinical risk. Most patients stayed in place, but new arrivals were redirected, and 11 patients in time-sensitive maternity or neonatal care were transferred as a precaution. Nonurgent work slowed so personnel and reliable power could remain focused on essential care.

Ambulance Diversions

Incoming ambulances were diverted while teams assessed electrical stability and restored clinical systems. Diversion prevents new demand from entering a facility with reduced capacity; it does not require every patient inside to move. Dispatchers and hospitals need current information on beds, specialties, travel time, and urgency. Diversions continued briefly after electricity returned while systems were checked.

Patient and NICU Transfers

Five newborn intensive care patients and six women in labor moved to other area hospitals as a precaution. Such transfers require clinical escorts, prepared receiving teams, records, medication continuity, monitored transport, and a clear handoff. They do not show that every NICU or maternity patient faced immediate danger. Officials reported no patient harm connected with the outage.

Postponed Elective Procedures

Elective surgeries and nonurgent procedures were postponed or minimized until the power system was stable. The Eccles Outpatient Care Center, Medical Office Building, and other outpatient operations closed for the day, and appointments were rescheduled. This helped preserve staff, sterile processing, ventilation, monitoring systems, elevators, and recovery beds for emergency care.

Critical Services Kept on Emergency Power

Critical areas such as intensive care, surgery, and preparation rooms continued operating with emergency support, although reports indicate that backup power was sharply reduced for a period. Ventilators continued working because they had built-in batteries. However, battery backup for individual medical devices is only one part of emergency support. Batteries still need to be recharged, medical gases must remain available, staff need reliable communications, and patient rooms must remain safe.

How Did the Hospital and Emergency Agencies Respond?

The response paired internal procedures with regional aid. Hospital command reduced demand, protected critical units, organized transfers, and worked with fire, utility, ambulance, and receiving-hospital partners while technical teams assessed the failure.

Hospital Emergency Procedures

Intermountain activated its emergency response system. Teams identified critical loads, monitored patients, restricted elective activity, closed affected outpatient sites, and communicated with public-safety partners. Chief Nursing Officer Brian Pendleton said the hospital drills for such incidents. Rehearsals establish roles, escalation paths, contact lists, and transfer criteria before a crisis begins.

Ambulance and Helicopter Coordination

During the outage, ground ambulances were redirected to other hospitals, and an Intermountain Life Flight helicopter was also seen leaving the medical center. Reports did not confirm who was on the helicopter, so it is unclear whether it was carrying a patient affected by the outage. In situations like this, ambulance dispatchers, ground crews, air medical teams, and nearby hospitals need up-to-date information so patients can be sent to facilities that are able to receive them safely.

Support From Utilities and Regional Partners

Hospital engineers worked with Murray Fire Department, city utilities, and technical partners to restore service and investigate. Nearby hospitals accepted maternity and NICU patients while emergency medical services changed destinations. Later testing involved local and national experts, and Intermountain prioritized upgrades and technical adjustments even though investigators had not isolated one root cause.

When Was Power Restored and What Happened Next?

Full electrical service was reported restored at about 1 p.m. on August 14. However, the return of power did not immediately restore normal hospital operations. Teams needed to verify clinical equipment, network access, communications, elevators, alarms, and other building systems before fully resuming regular patient flow.

Ambulance diversions and some postponed elective activities continued temporarily while staff confirmed that critical systems were stable. The medical campus returned to normal operations on August 15.

After the incident, Intermountain Health reviewed the outage with internal teams and external experts to identify contributing factors and strengthen future preparedness. The hospital later reported that the exact root cause remained undetermined and that technical improvements were being considered to reduce the risk of similar disruptions.

What the Outage Shows About Hospital Power Preparedness

A medical center power outage exposes dependencies that stay hidden during normal service. Resilience requires layered electrical design, clinical fallback procedures, regional coordination, and repeated testing under realistic conditions. A generator alone is not a complete plan, especially when the initiating failure can affect more than one layer.

Critical Loads Need More Than a Single Backup Layer

Hospitals need engineered, code-compliant emergency power systems with selective load priorities, independent controls, fuel and battery plans, preventive maintenance, safe transfer equipment, and frequent testing. Device batteries can bridge a short interruption for ventilators, monitors, pumps, or communications, while generators and other sources stabilize larger loads. Facilities teams must also plan for cooling, medical gases, information systems, elevators, and charging.

Regional Patient-Transfer Plans Matter

A large hospital cannot solve every outage inside its own walls. Transfer agreements should specify which partners can receive trauma, maternity, neonatal, cardiac, and other specialized patients; how records and medications travel; who authorizes movement; and which dispatch channels carry updates. Capacity information must remain current. The 11 precautionary transfers in Murray show why patient matching matters more than simply choosing the nearest building. Plans also need contingencies for traffic, severe weather, simultaneous regional outages, and limited ambulance availability.

Drills Help Teams Act Quickly Under Pressure

Written procedures become useful only after people practice them. Drills should test normal-power loss, delayed generator start, partial backup failure, network downtime, elevator restrictions, fuel problems, and a surge of incoming patients. Observers should record decision times, missed notifications, equipment that lacks charged batteries, and unclear authority. After-action reviews then assign owners and deadlines. Intermountain leaders credited prior drills with helping teams respond rapidly; the longer investigation also shows why exercises must challenge assumptions instead of confirming that the expected sequence works.

Prepare Your Home for Power Outages With BLUETTI Backup Solutions

The Intermountain Medical Center outage demonstrated how critical reliable electricity is for healthcare. While hospitals rely on professionally designed emergency power systems and clinical protocols, power interruptions can also create challenges for people who depend on medical equipment at home.

For households with power-dependent medical needs, preparing before an outage is essential. A backup plan should consider the equipment's power requirements, expected runtime, charging needs, and guidance from the device manufacturer or healthcare provider. Homeowners can explore backup power for home solutions to support selected essential loads, including medical-related equipment, refrigeration, lighting, and communication devices when appropriate.

For shorter interruptions or essential low-power devices, the BLUETTI Elite 100 V2 offers 1,024Wh of capacity and 1,800W of output for portable household backup needs.

For households requiring higher output or longer runtime, the BLUETTI Apex 300 provides 2,764.8Wh of built-in capacity and 3,840W of output, with compatible expansion options. Users should confirm compatibility with any medical device before relying on a backup power system during an outage.

Conclusion

The Intermountain Medical Center outage lasted less than two hours, yet it forced ambulance diversions, 11 precautionary maternity and NICU transfers, outpatient closures, and delayed elective care. Emergency procedures, device batteries, transport partners, and rehearsed staff actions protected patients while power was restored. The unresolved cause reinforces the value of multiple independent layers and continued testing. Households can apply the same principle at a smaller scale by planning essential loads and exploring a properly sized BLUETTI option without confusing consumer backup with hospital infrastructure.

FAQs

When Did the Intermountain Medical Center Power Outage Happen?

The outage began at approximately 11:15 a.m. on Thursday, August 14, 2025, at Intermountain Medical Center in Murray, Utah. Full electrical service was reported restored at about 1 p.m. Clinical and technical checks continued afterward, and the campus returned to normal operations the following day.

What Caused the Intermountain Medical Center Power Outage?

The root cause was not publicly confirmed. Murray officials said the event did not appear to originate with Murray City Power. Intermountain Health later reported that local and national experts had completed more than 100 tests without isolating the cause. Because the investigation did not identify a definitive cause, any early explanations should be treated as unconfirmed theories rather than established facts.

Were Patients Transferred to Other Hospitals?

Yes. Hospital officials said five newborn intensive care patients and six women in labor were transferred to other area hospitals as a precaution. Ambulances carrying new patients were also diverted temporarily. Most of the more than 500 people already in the hospital remained there, and officials reported no outage-related patient harm.

Did Intermountain Medical Center Have Backup Power?

Yes. Backup generators initially started, but hospital leaders said generator power was also lost during the incident, leaving parts of the campus with no power or minimum emergency power for a period. Some critical services continued, and ventilators had device batteries. This event shows why hospitals need several backup power sources in case one fails.
