Section 13.131. Records of Utility; Rates, Methods, and Accounts

Sec. 13.131. RECORDS OF UTILITY; RATES, METHODS, AND ACCOUNTS. (a) Every water and sewer utility shall keep and render to the regulatory authority in the manner and form prescribed by the utility commission uniform accounts of all business transacted. The utility commission may also prescribe forms of books, accounts, records, and memoranda to be kept by those utilities, including the books, accounts, records, and memoranda of the rendition of and capacity for service as well as the receipts and expenditures of money, and any other forms, records, and memoranda that in the judgment of the utility commission may be necessary to carry out this chapter.
(b) In the case of a utility subject to regulation by a federal regulatory agency, compliance with the system of accounts prescribed for the particular class of utilities by that agency may be considered a sufficient compliance with the system prescribed by the utility commission. However, the utility commission may prescribe forms of books, accounts, records, and memoranda covering information in addition to that required by the federal agency. The system of accounts and the forms of books, accounts, records, and memoranda prescribed by the utility commission for a utility or class of utilities may not conflict or be inconsistent with the systems and forms established by a federal agency for that utility or class of utilities.
(c) The utility commission shall fix proper and adequate rates and methods of depreciation, amortization, or depletion of the several classes of property of each utility and shall require every utility to carry a proper and adequate depreciation account in accordance with those rates and methods and with any other rules the utility commission prescribes. Rules adopted under this subsection must require the book cost less net salvage of depreciable utility plant retired to be charged in its entirety to the accumulated depreciation account in a manner consistent with accounting treatment of regulated electric and gas utilities in this state. Those rates, methods, and accounts shall be utilized uniformly and consistently throughout the rate-setting and appeal proceedings.
(d) Every utility shall keep separate accounts to show all profits or losses resulting from the sale or lease of appliances, fixtures, equipment, or other merchandise. A profit or loss may not be taken into consideration by the regulatory authority in arriving at any rate to be charged for service by a utility to the extent that the merchandise is not integral to the provision of utility service.
(e) Every utility is required to keep and render its books, accounts, records, and memoranda accurately and faithfully in the manner and form prescribed by the utility commission and to comply with all directions of the regulatory authority relating to those books, accounts, records, and memoranda. The regulatory authority may require the examination and audit of all accounts.
(f) In determining the allocation of tax savings derived from application of methods such as liberalized depreciation and amortization and the investment tax credit, the regulatory authority shall equitably balance the interests of present and future customers and shall apportion those benefits between consumers and the utilities accordingly. If any portion of the investment tax credit has been retained by a utility, that amount shall be deducted from the original cost of the facilities or other addition to the rate base to which the credit applied to the extent allowed by the Internal Revenue Code.
(g) Repealed by Acts 1987, 70th Leg., ch. 539, Sec. 32, eff. Sept. 1, 1987.
