Compliance Analysis
Key implementation requirements and action items for compliance with this legislation
Implementation Timeline
Effective Date: June 20, 2025
Compliance Deadline:Immediate. While filings occur later, you must begin internal accounting deferrals immediately upon the effective date to capture eligible costs for assets placed in service.
Agency Rulemaking: The Railroad Commission (RRC) must adopt implementing rules by March 17, 2026 (270 days post-effective).
*Regulatory Gray Zone:* From June 20, 2025, to March 2026, you are operating under the statute without finalized agency rules. Conservative accounting is advised to avoid future clawbacks.
Immediate Action Plan
1.Segregate Assets: Immediately identify "Unrecovered Gross Plant" in your General Ledger—assets in service but not yet in rates.
2.Establish Codes: Direct the Controller to create specific regulatory asset account codes for carrying costs, depreciation, and taxes associated with these assets.
3.Calculate Daily: Begin applying the Pre-tax WACC from your last Final Order to these assets effective June 20, 2025.
4.Prepare Comments: Direct Regulatory Counsel to draft comments for the upcoming RRC rulemaking, specifically advocating for a favorable definition of the refund interest rate.
Operational Changes Required
Contracts
Statement of Intent Filings: Legal teams must update templates for future rate case filings to explicitly include a schedule for the regulatory asset established under Section 104.302.
Lending Covenants: Review credit agreements. Ensure that this new "regulatory asset" is recognized as a valid asset class for the purpose of EBITDA/Interest coverage ratios, as this improves balance sheet health prior to cash recovery.
Hiring/Training
Regulatory Accounting: Finance teams require immediate training on the specific formula for "Post In-Service Carrying Costs": *(Unrecovered Gross Plant) × (Pre-tax WACC from most recent final rate order)*.
Asset Management: Operational staff must be retrained on the critical importance of documenting the exact "placed in service" date, as this date triggers the accrual eligibility.
Reporting & Record-Keeping
Audit Trails: You must maintain a rigorous audit trail linking specific physical assets (Unrecovered Gross Plant) to the regulatory asset account.
Tax Allocation: Ad valorem tax invoices must be specifically allocated to the unrecovered assets to justify the deferral entry.
Accounting Adjustments: You are legally required to book adjustments moving these costs from "regulatory asset" to "recovered rates" immediately upon RRC approval to prevent double recovery.
Fees & Costs
Refund Liability: There are no new state fees; however, the law creates a contingent liability. If the RRC disallows costs included in the regulatory asset during a rate review, you must refund those collected rates plus interest.
Strategic Ambiguities & Considerations
Interest Rate on Refunds: The statute mandates a refund "with interest" for disallowed costs but fails to define the rate (e.g., Customer Deposit Rate vs. WACC). This will be a critical battleground during the RRC rulemaking period.
GRIP Interaction: The RRC must clarify if this regulatory asset is recovered through the annual Gas Reliability Infrastructure Program (GRIP) interim adjustment or if it must sit as a separate line item until a full general rate case.
Depreciation Alignment: It remains unclear if depreciation rates used for the deferral must strictly match the last rate case or if updated study rates are permissible if a new study is underway.

The bill author has informed the committee that under current law, gas utilities must wait over a year before recovering costs on new infrastructure investments through customer rates, which puts a financial strain on utilities as the utilities must fund infrastructure investments without immediate cost recovery. The bill author has also informed the committee that during this waiting period, utilities incur costs but cannot recover them which makes it more challenging for utilities to finance ongoing infrastructure improvements and that this lag in cost recovery can slow down investment in safe and reliable gas distribution systems, which ultimately impacts consumers. C.S.H.B. 4384 seeks to address this issue by authorizing a gas utility to defer certain costs, depreciation, and property taxes for future recovery as a regulatory asset in order to mitigate regulatory lag, allow utilities to more efficiently reinvest in infrastructure improvements, and ensure that the state continues to have a safe and reliable gas distribution system.
CRIMINAL JUSTICE IMPACT
It is the committee's opinion that this bill does not expressly create a criminal offense, increase the punishment for an existing criminal offense or category of offenses, or change the eligibility of a person for community supervision, parole, or mandatory supervision.
RULEMAKING AUTHORITY
It is the committee's opinion that rulemaking authority is expressly granted to the Railroad Commission of Texas in SECTION 2 of this bill.
ANALYSIS
C.S.H.B. 4384 amends the Utilities Code to authorize a gas utility to defer the following for future recovery as a regulatory asset:
·post in-service carrying costs;
·depreciation associated with the unrecovered gross plant; and
·property taxes associated with the unrecovered gross plant.
The bill defines the following:
·"gross plant" as a gas utility's plant, facilities, or equipment that has been placed in service;
·"post in-service carrying costs" as the product of an unrecovered gross plant multiplied by a gas utility's pre-tax weighted average cost of capital established in the final order of the Railroad Commission of Texas (RRC) in the gas utility's most recent general rate proceeding, compounded at the gas utility's pre-tax weighted average cost of capital until recovery; and
·"unrecovered gross plant" as a gross plant whose cost is not yet being recovered in a gas utility's rates and not already being deferred to a regulatory asset.
C.S.H.B. 4384 requires a regulatory asset established under the bill's provisions to be included in the RRC's authorized cost recovery mechanism under statutory provisions relating to an interim adjustment in a gas utility's monthly customer charge or initial block rate for the recovery of the cost of changes in the investment in service for gas utility services. The bill requires a gas utility that establishes a regulatory asset under the bill's provisions, on recovery in rates of the regulatory asset, to make appropriate accounting adjustments to reflect the recovery in rates. The bill requires the RRC to review the costs included in a regulatory asset established by a gas utility under such provisions in a general rate proceeding. The bill establishes that the costs are subject to a refund with interest to the extent the RRC by order disallows recovery in rates.
C.S.H.B. 4384 requires the RRC to adopt rules to implement the bill's provisions not later than the 180th day after the bill's effective date.
C.S.H.B. 4384 applies only to a cost recovery proceeding commenced on or after the bill's effective date. A proceeding commenced before that date is governed by the law in effect on the date the proceeding was commenced, and the former law is continued in effect for that purpose.
EFFECTIVE DATE
On passage, or, if the bill does not receive the necessary vote, September 1, 2025.
COMPARISON OF INTRODUCED AND SUBSTITUTE
While C.S.H.B. 4384 may differ from the introduced in minor or nonsubstantive ways, the following summarizes the substantial differences between the introduced and committee substitute versions of the bill.
The substitute does not include the authorization in the introduced for a gas utility to defer for future recovery as a regulatory asset incremental operations and maintenance expense associated with the unrecovered gross plant that is not being recovered in rates.
With respect to the bill's provision establishing that costs included in a regulatory asset are subject to a refund to a certain extent, the introduced and the substitute differ as follows:
·the substitute includes a specification that was not in the introduced that such refund is with interest; and
·whereas the introduced specified such extent as the extent to which the RRC orders a disallowance, the substitute specifies such extent as the extent to which the RRC by order disallows recovery in rates.
