Texas electricity consumers who have a member of their household on life support equipment or who have a chronic condition for whom an interruption of power could result in a life-threatening condition may contact their TDU (power line company) to apply for chronic condition or critical care status. This status provides extra notification considerations, when possible, ahead of a storm or expected power interruption.

Chronic condition or critical care status does not guarantee an uninterrupted, regular, or continuous power supply. If electricity is a necessity, you must make other arrangements for on-site back-up capabilities or other alternatives in the event of loss of electric service. The application for this status requires verification from your healthcare provider and the form and further directions are available at:
