PSNC serves approximately 667,000 retail customers in North Carolina. In its general rate case application, PSNC requests authority to increase its rates and charges to produce additional overall annual North Carolina retail revenues of approximately $84,943,631, an increase of approximately 11% over current revenues. Further, PSNC is seeking approval of a rate of return on common equity of 10.60%. PSNC also seeks the following: (1) continuation of the Integrity Management Tracker Rider (Rider E) to recover capital expenses related to transmission and distribution integrity management programs; (2) authority to amortize and collect certain pipeline safety O&M expenses that have been deferred; (3) authority to implement Rider H – Pipeline Integrity Management Expenses Tracker to recover deferred operations and maintenance (O&M) expenses; (4) authority to implement a proposed Major Projects Cost Recovery Rider (MPR) to recover incremental costs associated with the M-71 pipeline, the Moriah Liquefied Natural Gas facility, and the non-Integrity Management Tracker rate base portion of the T-15 pipeline; (5) authority to defer and amortize extraordinary, nonrecurring costs associated with Hurricane Helene over a one-year period; (6) authority to implement a Customer Assistance Program (CAP) to provide eligible low-income customers with monthly, non-refundable bill credits during the winter months; (7) authority to implement a rider addressing liabilities from excess deferred income taxes (EDIT) associated with state corporate income tax reductions and to update previously approved EDIT regulatory liabilities due to an inadvertent miscalculation; and (8) approval to update and revise certain tariff provisions, primarily administrative in nature, without increasing basic facilities charges or miscellaneous fees. PSNC proposed that the new rates become effective May 1, 2025, but, assuming the Commission suspended the proposed rates and sets the matter for hearing, requested that the new rates become effective November 1, 2025. The Commission has issued an order on April 24, 2025 suspending PSNC’s proposed rate changes for a period of up to 270 days from the proposed effective date of May 1, 2025.

The Commission may consider additional or alternative rate design proposals that were not included in PSNC’s general rate case application and may order increases or decreases in individual rate schedules that differ from those proposed by PSNC, but the Commission will not consider any increase in total revenues beyond that requested by PSNC.
