Energy (Solar)

HB 801 removes a specific energy efficiency requirement for low-sloped roofs in Tennessee. It amends state law to clarify that the International Energy Conservation Code's roof solar reflectance and thermal emittance rules no longer apply to such roofs starting July 1, 2025. This change directly affects builders, developers, and homeowners constructing or renovating low-sloped roofs across Tennessee. The bill achieves this by adding a new provision to Tennessee Code Title 68, Chapter 120, eliminating the requirement without creating new rules. The law became effective April 3, 2025, with the policy change taking effect on July 1, 2025.

SB 884 clarifies that local governments (like cities or counties) must accept 19 specific energy sources - including solar, wind, nuclear, natural gas, and biomass - as "clean or green energy" when setting requirements for public utilities. It requires these local rules to include all 19 sources as permissible, regardless of whether the government labels the rules as targeting "clean" or "renewable" energy. The bill amends Tennessee law to define "energy project" and "public utility" consistently across multiple code sections. This change ensures utilities comply with local energy rules by using any of the listed sources, without requiring local governments to explicitly classify their requirements as "clean energy" or "renewable energy."

Senate Bill 1194 exempts low-sloped roofs in Tennessee from the 2021 International Energy Conservation Code's requirements for roof solar reflectance and thermal emittance, effective July 1, 2025. This change applies to all new construction and renovations involving low-sloped roofs, removing a specific energy efficiency standard that previously applied. The bill amends Tennessee state law to reflect this exemption and authorizes the state fire marshal to establish implementing rules. The exemption takes effect upon the bill's enactment.

HB 1143 clarifies that local governments (counties, cities) cannot restrict public utilities from using certain energy sources when creating regulations about clean or renewable energy. It requires all local energy requirements to include 19 specific sources as permissible, including solar, wind, nuclear power, natural gas, and biomass - regardless of how the local rule is worded. This directly affects municipal and county regulations governing utility energy sources and ensures utilities can comply by using any of the listed options. The bill amends multiple Tennessee code sections to define "clean or green energy" broadly and makes local rules that exclude these sources legally invalid.
