Texas Electricity Supply Chain Map

 

The Texas Electricity Supply Chain Map is a tool used by the Public Utility Commission of Texas (PUCT), the Railroad Commission (RRC), and state emergency responders to prepare for and respond to weather emergencies or other disasters that could impact electric grid reliability.

The map identifies critical infrastructure facilities in the state's electricity supply chain, including electric generation plants, natural gas facilities, and water and wastewater treatment plants. It is a crucial tool that allows state officials to respond to issues in real-time through direct communication and movement of resources to maintain or repair electric generation and transmission infrastructure during emergencies.

The map was created in April 2022 and is the first of its kind in the nation. Senate Bill 3, passed by the 87th Texas Legislature, required the PUCT and RRC to create the map, and Senate Bill 1093 (88th Legislature) later required the addition of Texas Department of Transportation (TxDOT) roads and water plants. The map is updated with critical infrastructure at least twice a year.

The map is overseen by the Texas Electricity Supply Chain Security and Mapping Committee, which is comprised of the Public Utility Commission, the Railroad Commission, the Electric Reliability Council of Texas, the Texas Division of Emergency Management, and the Texas Department of Transportation. The Committee holds regular public meetings which are posted to the PUCT’s calendar.
