Registering for priority restoration does not get your power back faster in a widespread outage
A power outage that lasts for days is exactly the situation Nashville Electric Service own medical equipment priority program is built for, and also the situation where its real limit shows up. The utility runs the Critical Referral Program, promising priority restoration to a household that registers an electrically powered medical device, verified by a doctor every 2 years. Winter Storm Fern, in January 2026, caused a power outage that cut electricity to more than 1,000,000 customers nationwide and became the largest outage on record for Nashville Electric Service. That storm shows exactly what registering for priority restoration does and does not do, because the same page that promises the priority also states its real limit in plain words. Registering does not get a household power back faster once a storm this size hits the whole system.
How big Winter Storm Fern actually was
At the peak of the storm, more than 1,000,000 customers were without power nationwide, and about 560,000 customers remained without power by midday the following Tuesday, mostly in the southeast, according to Verisk, a risk analytics company. Nashville Electric Service counted 230,000 customers without power at its own peak, nearly double the 130,000 customers cut by a derecho storm in March 2020, its prior worst outage. Around 800 poles broke across the system, and nearly 1,900 lineworkers worked 14 to 16 hour shifts around the clock in freezing temperatures. The Nashville Tennessean, digesting an independent review, reports 4 named Nashville residents died from causes tied to the storm, including hypothermia twice and carbon monoxide poisoning from a generator once.
The 2 nationwide rows are Verisk own figures, citing poweroutage.us, source 5. The Nashville Electric Service row is the utility own count, source 2, shown here for comparison against the nationwide toll. Verisk states the nationwide peak as more than 1,000,000. This chart shows the bare figure, 1,000,000, since axisLabel already carries the unit and this note carries the qualifier.

What the Critical Referral Program actually promises
Nashville Electric Service own Critical Referral Program page states plainly what registering buys a household. Critical Referral customers receive priority status during individual outages, the page states. It follows immediately with the real limit, the same limit the widespread reach of Winter Storm Fern put directly to the test.
However, during a widespread outage, system repairs must be completed before individual outages can be addressed.

Enrollment requires a resident to submit a Critical Referral Form, and a physician to submit a separate Critical Referral Verification Letter, resubmitted every 2 years. The utility tells an enrollee to have a backup plan in place for extended outages, warning that severe storms can cause significant damage that could take days to repair.
Why the Nashville outage ran longer than it needed to
Full restoration in Nashville took 12 days, and an independent review by PA Consulting Group found the wait could have been shorter. The largest wave of outside mutual aid crews did not arrive until 8 days into the restoration, and the review found that if those resources had been mobilized sooner, overall restoration time could have been reduced by approximately 2 to 5 days. Reading the program own promise next to the utility own restoration numbers together shows what registering for priority restoration actually means in a storm this size. It does not shorten a 12 day storm. It only moves a registered household up the list once system wide repairs are already finished, a narrower promise than the word priority might suggest to a reader deciding whether to sign up.
The independent review states earlier mobilization could have saved 2 to 5 days, a range, not a single number. This chart shows only the high end of that range, 5 days, so the bar is not read as more precise than the review states.
