(b)  In a rate proceeding under Subchapter D, or if requested by an electric utility in the utility's statement of intent initiating a rate proceeding under Subchapter C, notwithstanding Section 36.109(a), the final rate set in the proceeding, whether a rate increase or rate decrease, shall be made effective for consumption on and after the 155th day after the date the rate-filing package is filed.
(c)  The regulatory authority shall:
(1)  require the electric utility to refund to customers money collected in excess of the rate finally ordered on or after the 155th day after the date the rate-filing package is filed; or
(2)  authorize the electric utility to surcharge bills to recover the amount by which the money collected on or after the 155th day after the date the rate-filing package is filed is less than the money that would have been collected under the rate finally ordered.
(d)  The regulatory authority may require refunds or surcharges of amounts determined under Subsection (c) over a period not to exceed 18 months, along with appropriate carrying costs. The regulatory authority shall make any adjustments necessary to prevent over-recovery of amounts reflected in riders in effect for the electric utility during the pendency of the rate proceeding.
