Sec. 36.203.  FUEL AND PURCHASED POWER COST RECOVERY; ADJUSTMENT OF FUEL FACTOR.  (a)  Section 36.201 does not prohibit the commission from reviewing and providing for adjustments of an electric utility's fuel factor.
(b)  The commission by rule shall implement procedures that provide for the timely adjustment of an electric utility's fuel factor.  The rules must require that the findings required by Section 36.058 regarding fuel transactions with affiliated interests be made in a fuel reconciliation proceeding or in a rate case filed under Subchapter C or D.  The rules must ensure that:
(1)  the utility collects as contemporaneously as reasonably possible the electric fuel and purchased power costs that the utility incurs and that the commission determines are eligible;
(2)  the total of the utility's eligible electric fuel and purchased power costs, including any under-collected or over-collected amounts to be recovered through an interim fuel adjustment, is allocated among customer classes based on actual historical calendar month usage;
(3)  any material balance of amounts under-collected or over-collected for eligible electric fuel and purchased power costs is collected from or refunded to customers through an interim fuel adjustment:
(A)  not later than the 90th day after the date the balance is accrued; or
(B)  if the adjustment would result in a total bill increase of 10 percent or more compared to the total bill in the month before implementation, not later than a date ordered by the commission which must be after the 90th day after the date the balance is accrued; and
(4)  an affected party will receive notice and have the opportunity to request a hearing before the commission.
(c)  Notwithstanding Subsection (b)(3), on a finding that an electric utility has an under-collected balance that is the result of extraordinary electric fuel and purchased power costs that are unlikely to continue, the commission may approve an interim fuel adjustment that would defer recovery to take place over a period longer than 90 days.
(d)  The commission is not required to hold a hearing on the adjustment of an electric utility's fuel factor under this section.  If the commission holds a hearing, the commission may consider at the hearing any evidence that is appropriate and in the public interest.
(e)  A customer of the electric utility, a municipality with original jurisdiction over the utility, or the office may protest a fuel factor or interim fuel adjustment proposed under this section.  The prudence of costs may not be considered in a fuel factor or interim fuel adjustment proceeding and may only be considered in a fuel reconciliation proceeding under Subsection (h) or another appropriate proceeding.
(f)  The sole issue that may be considered on a protest of a fuel factor under Subsection (e) is whether the factor reasonably reflects costs the electric utility will incur so that the utility will not substantially under-collect or over-collect the utility's reasonably stated fuel and purchased power costs on an ongoing basis.  The commission may adjust the utility's fuel factor based on its determination on that issue.
(g)  The commission shall hold a hearing on a protest of an interim fuel adjustment under Subsection (e) if the adjustment would result in a total bill increase of 10 percent or more as described by Subsection (b)(3) or if the adjustment results from extraordinary electric fuel and purchased power costs as described by Subsection (c).  In response to a protest of an interim fuel adjustment, if the commission finds that the electric utility is in a state of material under-collection or over-collection of the utility's reasonably stated eligible fuel and purchased power costs and is projected to remain in that state on an ongoing basis, the commission shall order the utility to establish or modify an interim fuel adjustment to address the under-collection or over-collection in a manner consistent with this section.
(h)  An electric utility shall apply to reconcile the utility's electric fuel and purchased power costs at least once every two years.  The application must be made not later than the 180th day after the last day of the period to be reconciled.  The commission may by rule establish the calendar year timing of the reconciliation period for each electric utility subject to this section to facilitate efficient work by the commission.  To the extent a reconciliation results in a change to the electric utility's under-collected or over-collected fuel balance, that change may be incorporated into an interim fuel adjustment as directed by the commission.
(i)  A proceeding under this section is not a rate case under Subchapter C.
