Energy - As introduced, establishes a regulatory framework for solar energy facilities in this state. - Amends TCA Title 5; Title 6; Title 7, Chapter 51 and Title 65, Chapter 17.

HB 149 defines "solar energy facility" for regulatory purposes, excluding small residential systems under 5MW and equipment used in homes. It updates Tennessee code sections to replace "wind energy" with "utility" and adds specific rules for solar arrays, including setback requirements from property lines. Local governments can adopt their own solar siting regulations by July 1, 2025, and facilities built before that date are exempt from the new rules. The bill directly affects solar developers, local zoning authorities, and communities near proposed solar projects.
