Tex. Utilities Code § 104.365

(a) The railroad commission, on application of a gas utility to recover a regulatory asset, shall determine the regulatory asset amount to be recovered by the gas utility. A gas utility may request recovery of a regulatory asset under this subchapter only if the regulatory asset is related to Winter Storm Uri.

(b) A gas utility desiring to participate in the customer rate relief bond process under a financing order by requesting recovery of a regulatory asset must file an application with the railroad commission on or before the 60th day after the effective date of the Act enacting this subchapter.

(c) If the railroad commission does not make a final determination regarding the regulatory asset amount to be recovered by a gas utility before the 151st day after the gas utility files the application, the railroad commission is considered to have approved the regulatory asset amount requested by the gas utility.

(d) The regulatory asset determination is not subject to reduction, impairment, or adjustment by further action of the railroad commission, except as authorized by Section 104.370.

(e) The regulatory asset determination is not subject to rehearing by the railroad commission and may be appealed only to a Travis County district court by a party to the proceeding. The appeal must be filed not later than the 15th day after the date the order is signed by the railroad commission.

(f) The judgment of the district court may be reviewed only by direct appeal to the Supreme Court of Texas. The appeal must be filed not later than the 15th day after the date of entry of judgment.

(g) All appeals shall be heard and determined by the district court and the Supreme Court of Texas as expeditiously as possible with lawful precedence over other matters. Review on appeal shall be based solely on the record before the railroad commission and briefs to the court and limited to whether the financing order:

(1) complies with the constitution and laws of this state and the United States; and

(2) is within the authority of the railroad commission to issue under this subchapter.

(h) The railroad commission shall establish a schedule, filing requirements, and a procedure for determining the prudence of the costs included in a gas utility's regulatory asset.

(i) To the extent a gas utility subject to this subchapter receives insurance proceeds, governmental grants, or other sources of funding that compensate or otherwise reimburse or indemnify the gas utility for extraordinary costs following the issuance of customer rate relief bonds, the gas utility may record the amount in a regulatory liability account and that amount shall be reviewed in a future proceeding. If an audit conducted under a valid gas purchase agreement identifies a change of greater than five percent to the total amount of the gas supply costs incurred during the event for which regulatory asset recovery was approved, the gas utility may record the amount in a regulatory asset or regulatory liability account and that amount shall be reviewed for recovery in a future proceeding.
