52 Pa. Code § 53.56a – Supporting data required if using the fully projected future test year.

(a) In discharging its burden of proof under 66 Pa.C.S. § 315 (relating to burden of proof), a public utility may submit and use data for the FPFTY. The submission of information and data using the FPFTY is in addition to, and not in lieu of, other data or material required under this title, including the filing requirements for the HTY and the FTY.
(b) If the FPFTY is used, it must be based on fully substantiated estimates. The estimates for the FPFTY must be of the same or similar type, quantum and nature as required to be submitted for the HTY and the FTY and must describe the methodology, data and material used as the basis for the estimates.
(c) Following the completion of the rate proceeding, if the public utility’s FPFTY data form a substantive basis for the Commission’s final rate determination, the public utility shall file with the Commission and serve on the parties of record in the same docketed proceeding in which the final rate determination was entered, the public utility’s actual results experienced in the FPFTY. In this filing, the public utility shall provide appropriate data evidencing the accuracy of its estimates contained in the FPFTY. This filing must be submitted within 90 days of the end of the last quarter of the FPFTY. If the results are not then available, the public utility shall file and serve on the parties of record a status report indicating when the results will be available and shall file the results as soon thereafter as available.
