tariffs and schedules, as filed, effective December 1, 2025.

("Supplemental Compliance Filing")in Case No. IPC-E-25-24,requesting the Commission extend
the effective date of the updated tariffs and schedules to January 1, 2026, due to a timing conflict
regarding the implementation of the updated pricing elements.
On December 30, 2025, the Commission issued Final Order No. 36892 in Case No. IPC-
E-25-16, approving proposed tariff sheets in the Company's 2025 General Rate Case, effective
