Our customers count on us to provide continuous, reliable power – especially those who rely on life-sustaining electrical equipment. If this applies to you or someone at your home, you may be eligible for our Critical Care Program.


What Is It

Our Critical Care program is a registry of residential service locations where people rely on electric-powered, life-sustaining medical equipment. When planned outages or service interruptions for nonpayment are scheduled, we will attempt advance notice so preparations can be made.

In the event of ERCOT directed load shed, as much effort as possible to provide advance notice will be made, but circumstances do not always allow that to happen.

Important Info

In accordance with NBU policy and guidelines, customers designated as critical load are not guaranteed an uninterrupted supply of electricity. It is the responsibility of the customer to arrange for alternative sources of electric power in the event of a local outage, or ERCOT directed load shed event.

Locations registered in the program are not exempt from planned service interruptions, nor are registered members exempt from their financial responsibilities or from the termination of service in accordance with NBU policies.
