(a) Applicability. This section provides a mechanism for an electric utility to request to recover investment in a power generation facility through a generation cost recovery rider (GCRR) outside of a base-rate proceeding. This section applies only to an electric utility that operates solely outside of the Electric Reliability Council of Texas.
(b) Definitions. The following terms, when used in this section, have the following meanings unless context indicates otherwise.
  (1) GCRR billing determinant--Each rate class's annual billing determinant (kilowatt-hour, kilowatt, or kilovolt-ampere) for the previous calendar year.
  (2) Generation invested capital--The parts of the electric utility's invested capital for a power generation facility that will be functionalized as generation plant properly recorded in Federal Energy Regulatory Commission (FERC) Uniform System of Accounts 303 through 347, 352, and 353 when the generation facility is placed into service.
  (3) Power generation facility--A discrete facility or facilities constructed or purchased by an electric utility for use in generating electricity for public service by the electric utility, and the cost of which is not included in the electric utility's base rates. The term "facility" may encompass different parts of a single generation facility that begins providing service to the electric utility's customers on the same date.
  (4) Power generation facility invested capital--Generation invested capital associated with a power generation facility included in the electric utility's GCRR that will be placed into service before or at the time the GCRR becomes effective under subsection (g) of this section.
  (5) Power generation facility net invested capital--Power generation facility invested capital that is adjusted for accumulated depreciation and any changes in accumulated deferred federal income taxes, including changes to excess accumulated deferred federal income taxes, associated with all power generation facilities included in the electric utility's GCRR.
  (6) Weather-normalized--Adjusted for normal weather using weather data for the most recent ten-year period prior to the year from which the GCRR billing determinants are derived.
(c) GCRR Requirements. The GCRR rate for each rate class, and any other terms or conditions related to those rates, will be specified in a rider to the utility's tariff.
  (1) An electric utility must not have more than one GCRR.
  (2) An electric utility with an existing GCRR may apply to amend the GCRR to include the electric utility's actual capital investment in a power generation facility and additional power generation facilities.
  (3) Any GCRR established under this section will take effect on the date the power generation facility begins providing service to the electric utility's customers. Any amendment to an existing GCRR for an additional power generation facility will take effect on the date that the additional power generation facility begins providing service to the electric utility's customers.
  (4) As part of the next base-rate proceeding for the electric utility, the electric utility must request to move all investment being recovered in a GCRR into base rates and the GCRR will be set to zero.
(d) Calculation of GCRR Rates. The GCRR rate for each rate class must be calculated according to the provisions of this subsection and subsections (e) and (f) of this section.
  (1) The GCRR rates will not take into account changes in the number of the electric utility's customers and the effects that energy consumption and energy demand have on the amount of revenue recovered through the electric utility's base rates.
  (2) The GCRR rates must not include estimated costs.
  (3) The GCRR rate for each rate class will be calculated using the following formula: GCRRCLASS = RRCLASS / BDC-CLASS
  (4) The values of the terms used in this subsection will be calculated as follows:
    (A) RRCLASS = RRTOT * ALLOCC-CLASS
    (B) RRTOT = TRAF * ((PGFIC * RORRC ) + PGFDEPR + PGFFIT + PGFOT)
    (C) ALLOCC-CLASS = ALLOCRC-CLASS * (BDC-CLASS / BDRC-CLASS ) / Σ (ALLOCRC-CLASS * (BDC-CLASS / BDRC-CLASS ))
  (5) The terms used in this subsection represent or are defined as follows:
    (A) Descriptions of calculated values.
      (i) GCRRCLASS --GCRR rate for a rate class.
      (ii) RRCLASS --GCRR class revenue requirement.
      (iii) RRTOT --Total GCRR revenue requirement.
      (iv) ALLOCC-CLASS --GCRR class allocation factor for a rate class.
    (B) GCRR billing determinants and power generation facility values.
      (i) BDC-CLASS --GCRR billing determinants that are weather-normalized.
      (ii) PGFIC--Power generation facility net invested capital.
      (iii) PGFDEPR--Power generation facility depreciation expense.
      (iv) PGFFIT--Federal income tax expense associated with the return on the power generation facility net invested capital, reduced by any tax credits related to the power generation facility that are not returned to customers as a credit or other offset to eligible fuel expense.
      (v) PGFOT--Other tax expense associated with the power generation facility.
    (C) Baseline values. The following values are based on those values used to establish rates in the electric utility's most recent base-rate proceeding, or if an input to the GCRR calculation from the electric utility's last base-rate proceeding is not separately identified in that proceeding, it will be derived from information from that proceeding:
      (i) TRAF--Texas retail jurisdiction production allocation factor value used to establish rates in the electric utility's last base-rate proceeding determined under the provisions of subsection (e) of this section.
      (ii) BDRC-CLASS --Rate class billing determinants used to establish generation base rates in the last base-rate proceeding. Energy-based billing determinants will be used for those rate classes that do not include any rate demand charges, and demand-based billing determinants will be used for those rate classes that include rate demand charges.
      (iii) RORRC --After-tax rate of return approved by the commission in the electric utility's last base-rate proceeding.
      (iv) ALLOCRC-CLASS --Rate class allocation factor value determined under the provisions of subsection (e) of this section.
(e) Jurisdictional and class allocation factors. For calculating GCRR rates, the baseline jurisdictional and rate-class allocation factors used to allocate generation invested capital in the last base-rate proceeding will be used.
(f) Customer classification. For the purposes of establishing GCRR rates, customers will be classified according to the rate classes established in the electric utility's most recently completed base-rate proceeding.
(g) GCRR application. An electric utility may file an application for a GCRR before the electric utility places a power generation facility in service. An electric utility may include only one discrete power generation facility in an application for a GCRR. An electric utility may file an application to amend its GCRR to include another discrete power generation facility even if it has another application to amend its GCRR pending before the commission. The proceeding for a GCRR application must conform to the requirements of this subsection.
  (1) Scope of proceeding. The issues of whether generation invested capital included in an application for a GCRR complies with PURA and is prudent, reasonable, and necessary will not be addressed in a GCRR proceeding.
  (2) Notice. The applicant must notify all parties in the applicant's last base-rate proceeding that an application was filed. The notice must be provided by first-class mail and mailed the same day the application is filed. The notice must specify the docket number assigned to the application and a copy of the application must be included with the notice.
  (3) Parties and intervention. Requests to intervene must be filed no later than 10 calendar days after the date the application is filed. Objections to a request to intervene must be filed no later than five working days after the request is filed. All requests to intervene must be ruled upon no later than 21 calendar days after the application is filed.
  (4) GCRR forms. If the commission adopts a form for GCRR applications, an electric utility must file its application using that form.
