Should utility companies receive property tax exemptions for their power transmission and distribution equipment?
The South Carolina Administrative Law Court has ruled that Duke Energy transmission and distribution equipment is subject to state property taxes. The decision restricts the application of manufacturing exemptions to facilities located strictly at power plants.
Why it matters
The ruling clarifies the tax status of utility infrastructure by limiting manufacturing exemptions to production sites rather than the broader distribution network. This establishes a clearer compliance standard for utility companies regarding the taxation of assets like power lines, poles, and transformers.
The ruling affects all transmission and distribution equipment, including poles and transformers, belonging to Duke Energy Carolinas LLC and Duke Energy Progress LLC. The court confirmed these assets are ineligible for the manufacturing exemption currently granted to on-site plant equipment.
The players
Duke Energy Carolinas LLC
A subsidiary of a major U.S. utility company that operates power generation and distribution networks in the Carolinas.
Duke Energy Progress LLC
An electric utility provider and subsidiary of Duke Energy that serves customers across the Carolinas.
South Carolina Administrative Law Court
The state judicial body responsible for hearing contested cases involving agency actions and regulatory interpretations.
The details
The court determined that transmission infrastructure does not qualify as a manufacturing addition under the state's tax statutes. By restricting the exemption to equipment physically located at production facilities, the ruling excludes the lines and distribution systems that carry power to consumers. Operators should note that the court focused on the definition of the facility site rather than the function of the equipment itself.

Market Landscape
This ruling refines the application of the South Carolina statutory property tax exemption for manufacturing establishments. It clarifies a long-standing point of contention regarding whether grid infrastructure is eligible for the same tax status as on-site production hardware.
Operators in the energy sector should review their own asset portfolios to determine if similar equipment is currently classified under manufacturing exemptions. Consult with tax counsel to evaluate if this interpretation by the state court necessitates an adjustment in local property tax reporting.
The takeaway
The court has set a strict boundary for infrastructure tax exemptions, reinforcing that utility transmission is not a manufacturing activity. Review current tax filings and property classifications for transmission-related assets to ensure alignment with this new judicial interpretation.
