FAQ
What does the transmission and distribution footprint cover in Texas?
The utility delivers electricity to more than 400 communities across nearly 100 counties in Texas, operating high-voltage transmission lines and local distribution networks. The grid connects residential, commercial, and industrial customers and interfaces with ERCOT for wholesale dispatch and the Public Utility Commission of Texas (PUCT) for regulatory compliance.
How does the transmission network differ from the distribution network?
Transmission moves bulk power on high-voltage lines between generation sources and substations. Distribution takes that stepped-down voltage from substations to individual homes and businesses. Priorities for restoration typically follow transmission first, then critical facilities, major distribution feeders, and finally single-service connections.
How can I check whether a specific address is within the delivery footprint?
Use the interactive online map and address-lookup tool to view boundary overlays and provider information. Enter the physical address to see meter points, nearby substations, and which competitive retail electric providers are available at that location.
Where can I view live outage information and restoration estimates?
The outage dashboard presents near–real-time counts, cause classifications, and estimated restoration times. It includes an interactive storm center, facility-level impacts, and status updates. For urgent issues, use the published emergency contact numbers to report interruptions directly.
What are the typical causes reported on the outage map?
Common causes include severe weather (storms, lightning, wind), vegetation contact, equipment failure, and third‑party damage from vehicles or excavation. The system classifies incidents to assist crews in prioritizing repair sequencing and resource allocation.
How are power restoration priorities determined?
Crews prioritize transmission assets, hospitals and critical infrastructure, major distribution circuits serving many customers, and then single-customer outages. Restoration plans factor crew safety, parts availability, and access constraints such as flooding or debris.
What steps should a customer follow to report an outage?
Report outages via the utility’s outage portal, mobile app, or emergency phone numbers. Provide the service address, contact information, and any observed hazards. Customers with medical needs should register with the utility’s special‑needs program in advance.
What role does the delivery company play versus retail electric providers?
The delivery company maintains poles, wires, meters, and system reliability. Retail electric providers (REPs) sell generation and supply energy, set competitive rates, and manage customer billing options. Delivery charges appear on bills but are distinct from the energy supply charge.
How do I start new electric service for a home or business?
To initiate service, select a retail electric provider and submit an application; the delivery company schedules meter installation or re-energization. New commercial connections may require site inspections, load studies, and potentially distribution upgrades—allow additional lead time for larger loads.
What advanced metering and usage data options are available?
Advanced metering infrastructure (AMI) enables interval usage data, remote reads, and outage detection. Customers can access hourly consumption via the portal or third‑party authorized data providers to support energy management and demand-response programs.
What programs support energy efficiency and renewable adoption?
