H.B. 1143

# Legislative Summary: H.B. 1143 Tennessee House Bill 1143 expands the definition of acceptable energy sources that local governments and utilities can use to meet clean and renewable energy requirements by explicitly including nuclear power, natural gas, and various other technologies alongside traditional renewables like solar and wind. The bill's main purpose is to prevent local ordinances from restricting utilities to only certain energy sources, requiring that political subdivisions accept any of the nineteen listed sources—including nuclear and natural gas—as compliant with clean or green energy mandates. This legislation effectively limits local governments' ability to impose strict renewable-energy-only standards and voids any existing local regulations that conflict with this expanded definition, taking effect July 1, 2025.
