Medical Necessity Customers

Medical Necessity Customers

The Kerrville Public Utility Board maintains a medical necessity customer list comprised of residential locations in our service area where people rely on life-sustaining electrical equipment.

When planned outages in your service area are scheduled, we will make every attempt to provide advanced notice so that you can make necessary preparations. Additionally, during outages, your service location will receive high priority as we restore power.
To qualify, the service location must house someone diagnosed by a physician with one of the following medical conditions:


Diagnosed by a physician as requiring an electric-powered device to prevent the impairment of major life function.

Critical care:

Diagnosed by a physician as requiring an electric-powered device to sustain life.

Examples of qualifying medical or life support equipment include, but are not limited to the following:

  • Kidney dialysis
  • Apnea monitor for infants
  • Oxygen concentrator
  • Respirator/ventilator
  • Pressure breathing therapy (BiPAP/CPAP)
  • Infusion feeding pump
  • Peritoneal dialysis machine
  • Defibrillator

How to sign up

To have your account added to the list, KPUB will need a letter from your physician stating the necessity for life support equipment in your household on the physician’s official letterhead.
The letter can be returned to KPUB by email, mail or fax with the information found below.

This is a not a guarantee of electric service

Although KPUB provides reliable electric service, there is no guarantee of service. Outages may occur for a variety of reasons, including weather, equipment failure and mandated rotating outages. Medical necessity customers are still subject to rotating outage events.

Please note that enrollment in our medical necessity program for a chronic condition or critical care status does not guarantee an uninterrupted, regular or continuous power supply. Being on the medical necessity list will also not prevent service from being disconnected if your account becomes delinquent. We encourage all of our customers on the medical necessity list to develop an emergency plan in the case of a sustained outage. Your plan should include the use of emergency backup power like a generator.
