SB 2148 proposes amendments to Section 38.077 of the Texas Utilities Code to bolster the reliability and security of the state’s electrical grid infrastructure, particularly in the ERCOT power region. The legislation expands the existing requirements for load-shedding exercises by incorporating additional preparedness simulations that specifically address potential physical threats to critical electricity infrastructure, such as substations and control centers.
Under the bill, the Public Utility Commission (PUC) and the ERCOT-certified independent organization are mandated to conduct at least one tabletop or simulated load-shedding exercise during both the summer and winter months each year. Additionally, they must coordinate separate biennial exercises that simulate responses to physical attacks or credible threats against critical facilities. These exercises are designed to test and clarify the roles of key entities, including electric generation providers, transmission and distribution service providers, law enforcement, the PUC, and ERCOT.
SB 2148 includes provisions to maintain the confidentiality of infrastructure locations, ensuring that transmission providers are not compelled to disclose the specific locations of critical substations. It also requires participating utilities to provide written confirmation that they have coordinated with law enforcement in preparing their emergency response roles. The bill includes a deadline of December 31, 2026, by which the initial round of physical threat preparedness exercises must be conducted.
