If someone at home depends on electricity to stay well — a ventilator at night, an oxygen concentrator, a dialysis machine, or a fridge keeping medication cold — losing power isn't just an inconvenience. It's a health emergency. Texas protects these households from disconnection, and registering your account is one of the most important steps you can take. Here's how they work and how to sign up.
The short answer
Texas recognizes two residential medical designations. A Critical Care Residential Customer relies on electric-powered life-support equipment; a Chronic Condition Residential Customer has a serious condition that losing power would materially worsen. To qualify, a physician completes an official eligibility form, and you submit it to BOTH your Retail Electric Provider (REP) and your TDU — the wires company. It gives stronger disconnection protection, but it must be renewed, isn't a promise of first power back after a storm, and doesn't erase your bill.
The Two Designations Texas Recognizes
Under current Public Utility Commission of Texas (PUCT) rules, there are generally two ways a household can be flagged as medically vulnerable — and it helps to know which one fits you.
A Critical Care Residential Customer relies on electric-powered equipment for life support — a ventilator, an oxygen concentrator, or a dialysis machine. If the power goes out, that equipment stops, and the risk is immediate. A Chronic Condition Residential Customer has a serious condition that an interruption of service would materially worsen, even without constant life support — where losing heat, cooling, or a device for a stretch could send someone downhill fast. Both tell your utility the same thing: someone medically fragile lives here.
How to Get Registered
The process is the same for both, and it isn't complicated — it takes a form and a doctor. Ask your Retail Electric Provider or your TDU for the Critical Care / Chronic Condition eligibility form. Your TDU owns the poles and wires where you live — Oncor, CenterPoint, AEP Texas, or TNMP — and either one can point you to the current version.
Next, have your physician or another authorized provider complete and sign it — the medical judgment comes from them, not you. Then submit the completed form to BOTH your REP and your TDU. This is the step people miss: it only fully protects you once both companies have it on file, so don't stop after just one.
What the Designation Actually Does
Once you're registered, your account is flagged so the utility knows a medically vulnerable person lives there. For Critical Care customers, that means stronger protection from disconnection — providers must generally make extra attempts to reach you before any shutoff — and Chronic Condition status adds disconnection delay too. This adds to the safeguards every customer already has; for the full disconnection timeline, see our guide on how to stop an electricity disconnection in Texas.
What It Doesn't Do — Three Honest Limits
The designation is powerful, but it isn't magic. First, it's generally time-limited and must be renewed — often once a year — with a fresh physician form; let it lapse and the protection lapses with it. Second, it doesn't erase what you owe, so it works best paired with a plan for the money. Third, and most important, it is not a priority-restoration guarantee — after a major storm, it doesn't promise your street gets power back before anyone else's.
Never rely on the designation alone for life support
During an outage, the flag on your account can't make the lights come back any faster. Anyone on essential electric equipment needs a real backup power plan — a battery, a generator, or a safe place to go — and should tell their TDU that life-support equipment is in use.
During an Outage, Have a Backup Plan
Because the designation isn't a restoration guarantee, assume the power could still go out for a while. Plan ahead: know how your equipment runs on battery, whether you have a generator or somewhere to go, and how you'll keep medication cold. Notify your TDU that life-support equipment is in use. Our guide on preparing for a Texas power outage walks through that backup plan, and backup power for Texas outages compares the generator and battery options for a household that cannot afford to lose power.
Pair It With a Payment Plan and Assistance
Because the designation doesn't wipe out your bill, combine it with help on the money side. Texas has deferred payment plans, bill-payment assistance, and hardship programs that keep your balance manageable while your protection keeps you connected — we cover those in help paying your electricity bill in Texas, and you can browse every guide in our guides library. For official forms and current rules, the PUCT consumer help page is authoritative — confirm the latest form before you file.

How do I qualify as a Critical Care or Chronic Condition customer in Texas?
A physician or other authorized provider has to complete the official eligibility form, certifying either that you rely on electric-powered life-support equipment (Critical Care) or that losing power would materially worsen a serious medical condition (Chronic Condition). You then submit that completed form to both your Retail Electric Provider and your TDU. Ask either company for the current version of the form.
Does a medical designation stop my power from being disconnected in Texas?
It gives you significantly stronger protection. A Critical Care designation flags your account and generally requires your provider to make extra attempts to reach you before any shutoff, and Chronic Condition status adds disconnection delay and protection as well. It does not erase the balance you owe, though, so pair it with a payment plan so the designation is not the only thing standing between you and a shutoff.
Will critical care status get my power restored first after a storm?
No, and this is the most common misunderstanding. The designation flags your home as medically vulnerable, but it is not a priority-restoration guarantee. It does not promise your street comes back before others after a major outage. Anyone depending on electric medical equipment needs a real backup power plan and should tell their TDU directly that life-support equipment is in use.
Do I have to renew my Critical Care or Chronic Condition status?
Yes. The designation is generally time-limited and usually has to be renewed each year with a fresh physician form. If it lapses, so does the added protection. As of 2026 the exact renewal period and forms can change, so confirm the current requirements with your REP or TDU and set a reminder well before your designation is due to expire.
