Texas Utilities Code - UTIL § 163.015. Taxation

(a) A participating private entity shall render for ad valorem taxation its undivided fractional interest in a jointly owned electric facility. An ad valorem or similar tax shall be imposed separately against the undivided interest of the participating private entity.

(b) A tax or assessment, including an excise tax or sales and use tax, attributable to a property or service bought, sold, leased, or used to construct, maintain, repair, or operate a jointly owned electric facility shall be imposed separately against each participating entity in proportion to the entity's respective undivided interest in the facility.

(c) A participating entity is not liable for a tax or assessment attributable to another participating entity under Subsection (a) or (b).

(d) A participating entity is entitled to each constitutional or statutory ad valorem or other tax exemption attributable to the jointly owned electric facility or to a property or service bought, sold, leased, or used to construct, maintain, repair, or operate the facility to the extent the entity would have been exempt from the tax if the entity's undivided interest were an entire interest in the facility or in the property or service. The entity is entitled to any applicable exemption certificate or statement provided by law to claim or prove the exemption.
