Senate Bill 2502, also known as the "Electric Grid Resilience, Transparency, and Planning Act," aims to enhance the reliability and resilience of local electric systems in Tennessee. The bill introduces a new part to the Tennessee Code Annotated, specifically Title 7, Chapter 52, which outlines various requirements for local electric systems serving at least 10,000 customers. Key provisions include the obligation to publish an annual electric reliability and resilience report, a vegetation management plan, and a ten-year grid resilience plan. These documents must be accessible on the systems' websites and include metrics on reliability, outage management, and strategies for improving infrastructure resilience.

Additionally, the bill mandates that local electric systems provide after-action reports following significant outages and maintain minimum public communication standards during emergencies. The Tennessee board of utility regulation is tasked with establishing rules to enforce these requirements, including defining repeat outage areas and determining thresholds for public reporting. The act is set to take effect on July 1, 2026, and does not create a private cause of action against local electric systems for noncompliance.
