HomeMy WebLinkAboutItem 14 - Rate Review Mechanism SettlementMEMO TO: FROM: MEETING DATE: SUBJECT: RECOMMENDATION: FUNDING SOURCE: BACKGROUND: HONORABLE MAYOR AND MEMBERS OF THE CITY COUNCIL BRUNO RUMBELOW, CITY MANAGER SEPTEMBER 17, 2024 RESOLUTION APPROVING ATMOS RATE REVIEW MECHANISM TARIFF SETTLEMENT Staff recommends the City Council consider approval of a resolution of the Atmos RRM (Rate Review Mechanism) Tariff Settlement. The City, along with 181 other Mid-Texas cities served by Atmos Energy Corporation, Mid-Tex Division (“Atmos Mid-Tex” or “Company”), is a member of the Atmos Cities Steering Committee (“ACSC”). In 2007, ACSC and Atmos Mid-Tex settled a rate application filed by the Company pursuant to Section 104.301 of the Texas Utilities Code for an interim rate adjustment commonly referred to as a GRIP filing (arising out of the Gas Reliability Infrastructure Program legislation). That settlement created a substitute rate review process, referred to as Rate Review Mechanism (“RRM”), as a substitute for future filings under the GRIP statute. ACSC strongly opposed the GRIP process because it constitutes piecemeal ratemaking by ignoring declining expenses and increasing revenues while rewarding the Company for increasing capital investment on an annual basis. The GRIP process does not allow any review of the reasonableness of capital investment and does not allow cities to participate in the Railroad Commission’s review of annual GRIP filings or allow recovery of Cities’ rate case expenses. The Railroad Commission undertakes a mere administrative review of GRIP filings (instead of a full hearing) and rate increases go into effect without any material adjustments. In ACSC’s view, the GRIP process unfairly raises customers’ rates without any regulatory oversight. In contrast, the RRM process has allowed for a more comprehensive rate review and annual evaluation of expenses and revenues, as well as capital investment. In April the Company filed a rate request pursuant to the RRM Tariff adopted by ACSC members. The Company claimed that its cost-of- service in a test year ending December 31, 2023, entitled it to additional system-wide revenues of $196.8 million. Below details the portion of the request related to the ACSC cities and the related settlement numbers. $143.27 Million- Original request portion ascribed to ACSC Cities $132.6 Million-Modified request portion ascribed to the ACSC cities (Items are removed that should not have been included in the RRM request) $108.89 Million-Consultants reasonable finding portion ascribed to ACSC cities (consultants do a thorough examination of the request that includes checking calculations of the revenues and their sources and capital and operating expenses) $119.8 Million-Settlement portion for ACSC Cities (agreed upon between the Steering Committee and the Company to avoid costly and likely unfavorable Railroad Commission proceeding). The Executive Committee of ACSC recommends a systemwide settlement of $164.7 million. The effective date for new rates is October 1, 2024. The impact of the settlement on average residential rates is an increase of $5.52 monthly or 6.84%. The increase for average commercial usage will be $13.39 or 3.44%. Should the City choose not to accept the settlement, the rate increase request would go to the Railroad Commission where the City would be required to mount a costly intervention that would likely not reap any additional benefit for residents. The Council Utility Committee has reviewed this request. Staff recommends approval. RESOLUTION NO. 2024-015 A RESOLUTION OF THE CITY COUNCIL OF THE CITY OF GRAPEVINE, TEXAS, APPROVING A NEGOTIATED SETTLEMENT BETWEEN THE ATMOS CITIES STEERING COMMITTEE (“ACSC”) AND ATMOS ENERGY CORP., MID-TEX DIVISION REGARDING THE COMPANY’S 2024 RATE REVIEW MECHANISM FILING; DECLARING EXISTING RATES TO BE UNREASONABLE; ADOPTING TARIFFS THAT REFLECT RATE ADJUSTMENTS CONSISTENT WITH THE NEGOTIATED SETTLEMENT; FINDING THE RATES TO BE SET BY THE ATTACHED SETTLEMENT TARIFFS TO BE JUST AND REASONABLE AND IN THE PUBLIC INTEREST; APPROVING AN ATTACHMENT ESTABLISHING A BENCHMARK FOR PENSIONS AND RETIREE MEDICAL BENEFITS; REQUIRING THE COMPANY TO REIMBURSE ACSC’S REASONABLE RATEMAKING EXPENSES; DETERMINING THAT THIS RESOLUTION WAS PASSED IN ACCORDANCE WITH THE REQUIREMENTS OF THE TEXAS OPEN MEETINGS ACT; ADOPTING A SAVINGS CLAUSE; DECLARING AN EFFECTIVE DATE; AND REQUIRING DELIVERY OF THIS RESOLUTION TO THE COMPANY AND THE ACSC’S LEGAL COUNSEL. WHEREAS, the City of Grapevine, Texas (“City”) is a gas utility customer of Atmos Energy Corp., Mid-Tex Division (“Atmos Mid-Tex” or “Company”), and a regulatory authority with an interest in the rates, charges, and services of Atmos Mid-Tex; and WHEREAS, the City is a member of the Atmos Cities Steering Committee (“ACSC”), a coalition of similarly-situated cities served by Atmos Mid-Tex (“ACSC Cities”) that have joined together to facilitate the review of, and response to, natural gas issues affecting rates charged in the Atmos Mid-Tex service area; and WHEREAS, ACSC and the Company worked collaboratively to develop a Rate Review Mechanism (“RRM”) tariff that allows for an expedited rate review process by ACSC Cities as a substitute to the Gas Reliability Infrastructure Program (“GRIP”) process instituted by the Legislature, and that will establish rates for the ACSC Cities based on the system-wide cost of serving the Atmos Mid-Tex Division; and WHEREAS, the current RRM tariff was adopted by the City in a rate ordinance in 2018; and WHEREAS, on about April 1, 2024, Atmos Mid-Tex filed its 2024 RRM rate request with ACSC Cities based on a test year ending December 31, 2023; and Resolution No. 2024-015 2 WHEREAS, ACSC coordinated its review of the Atmos Mid-Tex 2024 RRM filing through its Executive Committee, assisted by ACSC’s attorneys and consultants, to resolve issues identified in the Company’s RRM filing; and WHEREAS, the Executive Committee, as well as ACSC’s counsel and consultants, recommend that ACSC Cities approve an increase in base rates for Atmos Mid-Tex of $164.7 million on a system-wide basis with an Effective Date of October 1, 2024; and WHEREAS, ACSC agrees that Atmos’ plant-in-service is reasonable; and WHEREAS, with the exception of approved plant-in-service, ACSC is not foreclosed from future reasonableness evaluation of costs associated with incidents related to gas leaks; and WHEREAS, the attached tariffs (Attachment 1) implementing new rates are consistent with the recommendation of the ACSC Executive Committee, are agreed to by the Company, and are just, reasonable, and in the public interest; and WHEREAS, the settlement agreement sets a new benchmark for pensions and retiree medical benefits (Attachment 2); and WHEREAS, the RRM Tariff contemplates reimbursement of ACSC’s reasonable expenses associated with RRM applications.

That, without prejudice to future litigation of any issue identified by ACSC, the City Council finds that the settled amount of an increase in revenues of $164.7 million on a system-wide basis represents a comprehensive settlement of gas utility rate issues affecting the rates, operations, and services offered by Atmos Mid-Tex within the municipal limits arising from Atmos Mid-Tex’s 2024 RRM filing, is in the public interest, and is consistent with the City’s authority under Section 103.001 of the Texas Utilities Code. Section 3. That despite finding Atmos Mid-Tex’s plant-in-service to be reasonable, ACSC is not foreclosed in future cases from evaluating the reasonableness of costs associated with incidents involving leaks of natural gas.

Attachment 1 MID-TEX DIVISION ATMOS ENERGY CORPORATION RIDER: WNA – WEATHER NORMALIZATION ADJUSTMENT APPLICABLE TO: ALL CUSTOMERS IN THE MID-TEX DIVISION UNDER THE RRM TARIFF EFFECTIVE DATE: Bills Rendered on or after 10/01/2024 Provisions for Adjustment The Commodity Charge per Ccf (100 cubic feet) for gas service set forth in any Rate Schedules utilized by the cities of the Mid-Tex Division service area for determining normalized winter period revenues shall be adjusted by an amount hereinafter described, which amount is referred to as the "Weather Normalization Adjustment." The Weather Normalization Adjustment shall apply to all temperature sensitive residential and commercial bills based on meters read during the revenue months of November through April. The five regional weather stations are Abilene, Austin, Dallas, Waco, and Wichita Falls. Computation of Weather Normalization Adjustment The Weather Normalization Adjustment Factor shall be computed to the nearest one-hundredth cent per Ccf by the following formula: (HSFi x (NDD-ADD) ) WNAFi = Ri (BLi +(HSFi x ADD) ) Where i = any particular Rate Schedule or billing classification within any such particular Rate Schedule that contains more than one billing classification WNAFi = Weather Normalization Adjustment Factor for the ith rate schedule or classification expressed in cents per Ccf Ri = Commodity Charge rate of temperature sensitive sales for the ith schedule or classification. HSFi = heat sensitive factor for the ith schedule or classification divided by the average bill count in that class NDD = billing cycle normal heating degree days calculated as the simple ten-year average of actual heating degree days. ADD = billing cycle actual heating degree days. Bli = base load sales for the ith schedule or classification divided by the average bill count in that class The Weather Normalization Adjustment for the jth customer in ith rate schedule is computed as: WNA i = WNAF i x q ij Where q ij is the relevant sales quantity for the jth customer in ith rate schedule.
