Utilities, Utility Districts - As introduced, requires each public and private electric utility and electric project developer, owner, or operator to conduct a technical assessment of certain electrical transformers to determine vulnerability to geomagnetically induced current; requires such entities to file a report on the assessment with the general assembly, governor, board of utility regulation, and the public utilities commission. - Amends TCA Title 4; Title 7 and Title 65.

SB 2565 requires Tennessee electric utilities and large transformer owners (public or private) to assess their high-voltage transformers (100kV+ and 25MVA+) for vulnerability to geomagnetically induced currents (GICs) caused by solar storms. By January 2027, these entities must complete technical assessments using specific industry standards and submit detailed reports by July 2027 to state officials. Reports must include transformer specifications, risk analysis, protection solutions, costs, and a priority list, while redacting sensitive location and operational details as "Critical Energy Infrastructure Information." The bill explicitly prohibits relying solely on operational fixes like load shedding for GIC protection.
