Relating to the reliability of the electricity supply chain.

SB 2148 requires Texas electricity providers in the ERCOT region to conduct annual simulated or tabletop exercises for load shedding during summer and winter months, plus additional exercises every two years focused on preparing for physical attacks on critical infrastructure like substations and control centers. It mandates that transmission, distribution, and generation providers coordinate with law enforcement and the independent grid operator to define roles during attacks, and submit written attestations confirming this coordination. The bill affects all major electricity service providers in Texas’ ERCOT power region, requiring them to participate in these drills. The first full implementation must occur by December 31, 2026, as specified in the bill’s timeline. These exercises aim to improve grid resilience by ensuring clear protocols for critical infrastructure threats.
