The Public Utility Commission of Texas (PUCT), alongside its partner regulatory agencies, has finalized updates to the Texas Electricity Supply Chain Map to strengthen state preparedness ahead of the upcoming hurricane season.
Designed as an interactive tool to illustrate exactly how electricity and natural gas systems interconnect across the state, the map serves as a vital resource for state emergency management teams. By visualizing these intersections, emergency responders can act rapidly to mitigate grid stress and protect citizens whenever a major disaster strikes the state.
The latest revisions introduce several critical tracking enhancements across the state’s energy and utility networks. First, all statewide power assets have been fully modernized, with the most current data on generation plants, transmission lines, and substations formally published. The state expanded its mapped natural gas infrastructure by incorporating updated data from the Railroad Commission of Texas (RRC) that covers a significantly higher volume of active gas wells.
Emergency and community systems have also been integrated into the digital platform, which now features localized emergency contacts for disaster districts, comprehensive Texas Department of Transportation (TxDOT) road data, and an expanded directory of regional water and wastewater treatment plants. The PUCT has successfully completed cross-system connection mapping by linking critical natural gas facilities directly to the specific electric substations and feeders that power them—a major milestone vetted and reviewed by local utilities to conclude this phase of the state’s supply chain mapping project.
State grid officials emphasized that these structural map updates are critical for providing state leaders with immediate visibility into infrastructure risks, allowing them to restore power faster during hurricanes, summer heat waves, and severe winter storms. While sensitive infrastructure security details remain protected under Texas law to safeguard the grid, the general public can access approved public data layers through the official PUCT website.
Moving forward, the Electricity Supply Chain Security and Mapping Committee will continue to convene quarterly — including one public meeting held annually — to review data. The committee is increasingly relying on ongoing inter-agency coordination and new automation tools to accelerate future map updates and optimize operational data accuracy to keep the lights on when it matters most.
