Relating to the recovery of certain costs associated with a gas utility's plant, facilities, or equipment placed in service.

HB 4384 allows gas utilities to defer certain unrecovered costs - like interest on unpaid infrastructure, depreciation, and property taxes - associated with facilities already in service. These deferred costs become "regulatory assets" that must later be recovered through customer rates. The Railroad Commission of Texas will review these costs during rate proceedings and may require refunds if costs are disallowed. This bill directly affects Texas gas utilities by changing how they account for and recover legacy infrastructure costs, without altering current rate structures.
