Energy - As introduced, requires an applicant and an electric utility service to perform and submit to the locality a site assessment prior to the approval of a rezoning request, special exception, or special use permit for the siting of a new high energy use facility (HEUF). - Amends TCA Title 5; Title 6; Title 7; Title 13; Title 54; Title 65 and Title 68.

HB 946 requires applicants and electric utilities to conduct and submit site assessments before local governments approve zoning changes or permits for new high energy use facilities (HEUFs), defined as projects needing 100+ megawatts of power (including large data centers). The assessments must examine sound impacts on homes and schools within 500 feet, as well as effects on water, agriculture, parks, and historic sites. Electric utilities must also detail required power infrastructure like new substations and transmission voltage. This bill directly affects developers of large energy projects, local zoning authorities, and electric utilities, applying only to new facilities - not expansions under 100 MW.
