Regulatory and Rate Matters

12 Months Ended

Dec. 31, 2024

The Company is involved in various regulatory matters, some of which contain contingencies that are subject to the same uncertainties as those described in Note 16.

PNM

New Mexico General Rate Case

2025 Rate Request

On June 14, 2024, PNM filed an application with the NMPRC for a general increase in retail electric rates. The proposed base rate changes would be implemented in two phases, with the first phase effective July 1, 2025 and the second phase effective January 1, 2026. Key aspects of PNM’s request include:

•Recovery on total rate base of $3.0 billion, based on a FTY with the 12 months ending June 30, 2026

•An increase of $174.3 million in retail revenues, comprised of a $92.2 million increase in base rates and a $82.1 million increase in revenues collected under PNM’s FPPAC

•Drivers of revenue deficiency:

◦Needed investments across distribution, transmission, and generation facilities to ensure safe, reliable delivery of electricity

◦Increased operations and maintenance expenses to meet operational needs, including wildfire risk mitigation

◦Costs associated with ESAs, previously approved by the NMPRC, necessary to serve our customers

◦ROE of 10.45%

◦Proposed capital structure of 52.5% equity

◦An increased cost of borrowing

◦Adjustments to Four Corners depreciation rates to recover remaining plant investments through July 2031, the expected abandonment date of the facility

•Proposed ratemaking treatment of ESAs to be recovered through PNM’s FPPAC beginning July 1, 2025

On November 26, 2024, PNM filed an unopposed comprehensive stipulation with the NMPRC. Key components agreed upon by the signatories are as follows:

•Overall revenue requirement increase of $105.0 million with the first phase effective July 1, 2025 and the second phase effective April 1, 2026

•ROE of 9.45%

•Capital structure of 51.0% equity

•Maintain currently approved depreciation rates for Four Corners as established in PNM’s 2024 Rate Change and PNM’s NM 2015 Rate Case

•Modification of PNM’s current amortization period through December 31, 2028 on the unprotected Excess Deferred Federal Income Taxes (“EDFIT”) regulatory liability to reflect amortization of remaining unprotected EDFIT through December 31, 2027

•Costs associated with ESAs shall be recovered through base rates

◦PNM will establish a regulatory asset or regulatory liability for the difference in actual ESA costs compared to the forecasted $82.1 million included in base rates in the test period and thereafter until new rates are effective from PNM’s next general rate case filing. The regulatory asset or regulatory liability will be subject to NMPRC approval in PNM’s next rate case

•PNM will establish a regulatory liability associated with investment tax credits for the Sandia energy storage system as proposed in its application

•PNM will establish a regulatory liability equal to the return on legacy meters currently included in rates, as the legacy meters are retired during PNM’s deployment of its grid modernization plan approved in PNM’s Grid Modernization Application

A hearing was held on February 17 and 18, 2025. PNM cannot predict the outcome of this matter.

2024 Rate Change

On December 5, 2022, PNM filed an application with the NMPRC for a general increase in retail electric rates including recovery on total rate base of $2.7 billion based on a calendar year 2024 FTY, an increase of $63.8 million in retail non-fuel revenues, and an ROE 10.25%. The application also proposed ratemaking treatment of PVNGS Leased Interest and testimony supporting the prudence of PNM’s decisions to renew the five leases and repurchase 64.1 MW of PVNGS Unit 2 capacity.

On January 3, 2024, the NMPRC issued a final order authorizing PNM to implement an increase in non-fuel base rates of $15.3 million, effective for service beginning January 15, 2024. Major components of the difference compared to PNM’s application include:

•A ROE of 9.26%.

•A capital structure of 49.61% equity, 50.10% debt, and 0.29% preferred stock.

•Finding of imprudence regarding PNM’s decision to remain in Four Corners and a remedy for the imprudence resulting in a disallowance of $81.0 million to PNM’s total Four Corners net book value.

•Approval of $51.3 million of PNM’s requested $96.3 million regulatory asset for PVNGS undepreciated investments, but disallowance of a return on the remaining $45.0 million or any CWIP associated with it.

•Requiring that the $38.4 million regulatory liability associated with leased capacity at PVNGS after the Unit 1 lease expired on January 15, 2023, be returned to ratepayers over two years through a separate rate rider.

•The approval of new depreciation rates, reflecting shorter useful lives, of PNM’s gas plants with service lives and depreciable lives extending beyond January 1, 2045, which would include PNM’s La Luz and Luna generating stations.

•The approval of PNM’s TOD pilot program, with a requirement to make annual compliance filings and to adjust certain rate schedules.

As a result of the NMPRC final order in the 2024 Rate Change, during the year ended December 31, 2023, PNM recorded a regulatory disallowance of $55.5 million on the Consolidated Statement of Earnings and a corresponding reduction to Utility Plant, after accounting for previous impairments, to reflect the remedy adopted in the Final Order for Four Corners. In addition, PNM recorded a reduction to electric operating revenues of $38.4 million with a corresponding current regulatory liability of $19.2 million and a deferred regulatory liability of $19.2 million for the PVNGS rate refunds that will be returned to customers over a two-year period. PNM also recorded a regulatory disallowance of $8.2 million on the Consolidated Statement of Earnings and a corresponding reduction to Utility Plant for the disallowance of CWIP from PVNGS.

In March 2024, notice of appeals were separately filed with the NM Supreme Court by NEE and PNM, and a joint notice of appeal was filed by the NM Department of Justice, Bernalillo County, and ABCWUA. NEE’s appeal was subsequently consolidated with the joint notice of appeal. In the statements of issues submitted in the parties’ appellate dockets, PNM took issue with the NMPRC’s ruling on capital structure; other appellants primarily challenged the NMPRC rulings related to Four Corners and Palo Verde cost recovery. PNM cannot predict the outcome of this matter.

Renewable Energy Portfolio Standard

As discussed in Note 16, the ETA amends the REA including removal of diversity requirements and certain customer caps and exemptions relating to the application of the RPS under the REA. The REA provides for streamlined proceedings for approval of utilities’ renewable energy procurement plans, assures that utilities recover costs incurred consistent with approved procurement plans, and requires the NMPRC to establish a Reasonable Cost Threshold (“RCT”) for the procurement of renewable resources to prevent excessive costs being added to rates. The ETA sets a RCT of $60 per MWh, adjusted for inflation, using an average annual levelized resource cost basis. PNM makes renewable procurements consistent with the NMPRC approved plans and recovers certain renewable procurement costs from customers through the renewable energy rider billed on a KWh basis.

Included in PNM’s approved procurement plans are the following renewable energy resources:

•158 MW of PNM-owned solar-PV facilities

•A PPA through 2044 for the output of New Mexico Wind, having a current aggregate capacity of 200 MW, and a PPA through 2035 for the output of Red Mesa Wind, having an aggregate capacity of 102 MW

•A PPA through 2040 for 140 MW of output from La Joya Wind II

•A PPA through 2042 for the output of the Lightning Dock Geothermal facility with a capacity of 11 MW

•Solar distributed generation, aggregating 308.5 MW at December 31, 2024, owned by customers or third parties from whom PNM purchases any net excess output and RECs

The NMPRC has authorized PNM to recover certain renewable procurement costs through a rate rider billed on a per KWh basis. In its 2024 renewable energy procurement plan, which became effective on January 1, 2024, PNM proposed to collect $59.0 million for the year. On June 3, 2024, PNM filed its renewable energy procurement plan for 2025 which proposes to collect $58.7 million for the year. PNM did not propose any new resource procurements, and the plan states that existing projects are anticipated to exceed the applicable RPS standards of 2025, despite the standard doubling. On September 11, 2024, a public hearing was held and on October 11, 2024, the hearing examiners issued a RD recommending approval of all PNM’s requests. On November 14, 2024, the NMPRC issued an order adopting the recommended decision. The 2025 renewable energy procurement plan became effective on January 1, 2025.

The following sets forth PNM’s revenues recorded for the renewable energy rider:


Year Ended						Annual Revenues
						(In millions)
2022						$60.3
2023						56.9
2024						52.0

Under the renewable rider, if PNM’s earned rate of return on jurisdictional equity in a calendar year, adjusted for items not representative of normal operations, exceeds the NMPRC-approved rate by 0.5%, PNM is required to refund the excess to customers during May through December of the following year. PNM does not expect to exceed the limitation in 2024.

Energy Efficiency and Load Management

Program Costs and Incentives/Disincentives

The New Mexico EUEA requires public utilities to achieve specified levels of energy savings and to obtain NMPRC approval to implement energy efficiency and load management programs. The EUEA requires the NMPRC to remove utility disincentives to implementing energy efficiency and load management programs and to provide incentives for such programs. The NMPRC has adopted a rule to implement this act. PNM’s costs to implement approved programs and incentives are recovered through a rate rider. During the 2019 New Mexico legislative session, the EUEA was amended to, among other

things, include a decoupling mechanism for disincentives, preclude a reduction to a utility’s ROE based on approval of disincentive or incentive mechanisms, establish energy savings targets for the period 2021 through 2025, and require that annual program funding be 3% to 5% of an electric utility’s annual customer bills excluding gross receipt taxes, franchise and right-of-way access fees, provided that a customer’s annual cost does not exceed seventy-five thousand dollars.

In 2020, PNM received approval for energy efficiency and load management programs to be offered in 2021, 2022, and 2023. The program portfolio consisted of twelve programs with a total annual budget of $31.4 million in 2021, $31.0 million in 2022, and $29.6 million in 2023. The program included an annual base incentive of 7.1% of the portfolio budget if PNM were to achieve energy savings of at least 80 GWh in a year. The incentive increases if PNM is able to achieve savings greater than 94 GWh in a year.

In 2023, PNM filed an application for energy efficiency and load management programs to be offered in 2024, 2025, and 2026 (the “2024 Plan”). The 2024 Plan proposed to continue ten existing energy efficiency programs with modification and a total annual budget of $34.5 million in 2024, $35.4 million in 2025, and $36.5 million in 2026. The application also sought approval of an annual base incentive of 7.1% of the portfolio budget and a sliding scale that provides additional incentive for additional energy saved as a percentage of program cost, up to the maximum allowed by the energy efficiency rule which for PNM is 8.82%. On January 26, 2024, the hearing examiners in the case issued a RD. The RD largely approved PNM’s 2024 Plan but with modifications that include the pursuit of demand response resources, additional analysis in future filings, adjustments to certain energy efficiency programs, and modification of the incentive sliding scale cap to reflect a new maximum. On March 7, 2024, the NMPRC approved the RD in its entirety.

2020 Decoupling Petition

As discussed above, the legislature amended the EUEA to, among other things, include a decoupling mechanism for disincentives. On May 28, 2020, PNM filed a petition for approval of a rate adjustment mechanism that would decouple the rates of its residential and small power rate classes. Decoupling is a rate design principle that severs the link between the recovery of fixed costs of the utility through volumetric charges. On July 13, 2020, NEE, ABCWUA, the City of Albuquerque, and Bernalillo County filed motions to dismiss the petition on the grounds that approving PNM’s proposed rate adjustment mechanism outside of a general rate case would result in retroactive ratemaking and piecemeal ratemaking. The motions to dismiss also alleged that PNM’s proposed rate adjustment mechanism is inconsistent with the EUEA. On October 2, 2020, PNM requested an order to vacate the public hearing, scheduled to begin October 13, 2020, and staying the proceeding until the NMPRC decides whether to entertain a petition to issue a declaratory order resolving the issues raised in the motions to dismiss. On October 7, 2020, the hearing examiner approved PNM’s request to stay the proceeding and vacate the public hearing and required PNM to file a petition for declaratory order by October 30, 2020. On October 30, 2020, PNM filed a petition for declaratory order asking the NMPRC to issue an order finding that full revenue decoupling is authorized by the EUEA. On November 4, 2020, ABCWUA and Bernalillo County jointly filed a competing petition asking the NMPRC to issue a declaratory order on the EUEA’s requirements related to disincentives. On March 17, 2021, the NMPRC issued an order granting the petitions for declaratory order, commencing a declaratory order proceeding to address the petitions and appointing a hearing examiner to preside over the declaratory order proceeding.

On January 14, 2022, the hearing examiner issued a RD recommending the NMPRC find that the EUEA does not mandate the NMPRC to authorize or approve a full decoupling mechanism, defining full decoupling as limited to energy efficiency and load management measures and programs. The RD also states that a utility may request approval of a rate adjustment mechanism to remove regulatory disincentives to energy efficiency and load management measures and programs through a stand-alone petition, as part of the utility’s triennial energy efficiency application or a general rate case and that PNM is not otherwise precluded from petitioning for a rate adjustment mechanism prior to its next general rate case. Finally, the RD stated that the EUEA does not permit the NMPRC to reduce a utility’s ROE based on approval of a disincentive removal mechanism founded on removing regulatory disincentives to energy efficiency and load management measures and programs. The RD does not specifically prohibit a downward adjustment to a utility’s capital structure, based on approval of a disincentive removal mechanism. On April 27, 2022, the NMPRC issued an order adopting the RD in its entirety. On May 24, 2022, PNM filed a notice of appeal with the NM Supreme Court. The NM Supreme Court held oral arguments on November 13, 2023. On May 13, 2024, the NM Supreme Court issued a decision finding that the EUEA allows a utility to propose full decoupling mechanisms. The NM Supreme Court did not address the second issue regarding a downward adjustment to a utility’s capital structure based on approval of disincentive removal mechanism. No declaratory order was issued by the NMPRC. This matter is now concluded.

Integrated Resource Plans

NMPRC rules require that investor-owned utilities file an IRP every three years. The IRP is required to cover a 20-year planning period and contain an action plan covering the first three years of that period. On September 14, 2022, the NMPRC adopted revisions to the IRP Rule. The new rule revamps and modernizes the planning process to accommodate increased stakeholder involvement. The IRP Rule establishes a collaborative facilitated process for a utility and stakeholders to agree on a statement of need for potential new or additional resources, as well as an action plan to guide procurement or development of resources to meet the stated need. A most-cost-effective portfolio of resources shall be derived from the statement of need analysis. The statement of need and action plan must be accepted before the utility begins the resource solicitation process pursuant to the IRP Rule. Following acceptance of the statement of need and action plan, a utility will provide the NMPRC and intervenors drafts of the RFP and a timeline for issuing, receiving, evaluating, and ranking bids. The NMPRC will then appoint an Independent Monitor (“IM”) to oversee the RFP process, which allows for parties and the IM to comment on the RFP consistency with the IRP, after which the utility issues the RFP. Within 120 days of receiving bids the utility shall provide the IM with results including pricing and non-price evaluation criteria, ranking of bids, chosen portfolio and alternatives that also meet the needs; the IM then rules on the fairness of the RFP execution. Acceptance of the statement of need and action plan will not constitute a finding of prudency or pre-approval of costs associated with the additional resources. Following the RFP and IM processes, the utility may apply for approvals, and any costs incurred to implement the action plan will be considered in a general rate case and/or resource acquisition proceeding. On October 14, 2022, PNM and other investor-owned utilities filed motions for rehearing with the NMPRC. On October 26, 2022, the NMPRC issued an order partially granting and partially denying certain aspects of PNM’s and the other investor-owned utilities’ motions for rehearing. On November 2, 2022, the NMPRC adopted an amended IRP Rule. On December 2, 2022, PNM filed an appeal with the NM Supreme Court. Two other investor-owned utilities also separately filed appeals at the NM Supreme Court. On January 3, 2023, PNM and the two other investor-owned utilities filed statements of issues with the NM Supreme Court. Among other things, the investor-owned utilities question whether the IRP Rule exceeds the NMPRC authority by imposing unauthorized requirements on utilities and extending NMPRC jurisdiction through over-broad interpretation of the statutes and state that the IRP Rule is contrary to law in its provisions for NMPRC regulation of a utility’s resource procurement decision-making. On June 5, 2023, PNM and the other two investor-owned utilities filed their Joint Brief in Chief and request for oral arguments at the NM Supreme Court. The NM Supreme Court held oral arguments on May 13, 2024. On December 6, 2024, the NM Supreme Court issued a decision finding that the amended regulations do not exceed the statutory scope of the EUEA.

2023 IRP

On December 15, 2023, PNM filed its 2023 IRP with a continued focus on a carbon-free energy system by 2040. The plan highlights the need for the significant sustained addition of resources over the next two decades, replacing retiring or expiring capacity, meeting concurrent load growth, while reducing the carbon intensity of PNM’s portfolio. On April 4, 2024, the NMPRC accepted PNM’s 2023 IRP.

On December 30, 2024, PNM issued its 2029-2032 RFP for at least 900 MW of new energy resources to come online between 2029 and 2032, with at least 500 MW needed by 2030. The RFP is consistent with the needs identified in PNM’s 2023 IRP, which identified a range of 900 to 2,900 MW of new capacity needed by 2032, depending on the type of resources selected. The 2029-2032 RFP is anticipated to identify potential replacement resources for PNM’s current natural gas generation capacity as well as PNM’s ownership interest in Four Corners.

Abandonment Applications made under the ETA

As discussed in Note 16, the ETA provides for a transition from fossil-fueled generating resources to renewable and carbon-free resources by allowing utilities to issue energy transition bonds related to the retirement of certain coal-fired generating facilities, to qualified investors.

SJGS Abandonment Application

In 2019, PNM filed a Consolidated Application for the Abandonment and Replacement of SJGS and Related Securitized Financing Pursuant to the ETA. In 2023, PNM, along with intervening parties reached a unanimous settlement which was approved by the NMPRC. As a result, PNM recorded a $128.7 million reduction to electric operating revenues in the Consolidated Statement of Earnings and a corresponding current regulatory liability on the Consolidated Balance Sheets as of and for the year ended December 31, 2023. In addition, PNM recorded a regulatory disallowance of $3.3 million on the Consolidated Statement of Earnings and a corresponding decrease to deferred regulatory assets on the Consolidated Balance

Sheets as of and for the year ended December 31, 2023, to reflect PNM’s agreement to withdraw its request for regulatory assets associated with prefunding of ETA state administered funds and legal costs associated with this matter.

Four Corners Abandonment Application

In 2020, PNM entered into the Four Corners Purchase and Sale Agreement with NTEC, pursuant to which PNM agreed to sell its 13% ownership interest (other than certain transmission assets) in Four Corners to NTEC, contingent upon NMPRC approval. In connection with the sale, PNM would make payments of $75.0 million to NTEC for relief from its obligations under the coal supply agreement for Four Corners after December 31, 2024. PNM made an initial payment to NTEC of $15.0 million in November 2020, subject to refund with interest upon termination of the Four Corners Purchase and Sale Agreement prior to closing. Under the terms of the Four Corners Purchase and Sale Agreement, upon receipt of the NMPRC approval, PNM was expected to make a final payment of $60.0 million.

On January 8, 2021, PNM filed the Four Corners Abandonment Application, which sought NMPRC approval to exit PNM’s share of Four Corners as of December 31, 2024, and issuance of approximately $300 million of Securitized Bonds as provided by the ETA. On December 15, 2021, the NMPRC issued a final order denying approval of the Four Corners Abandonment Application and the corresponding request for issuance of securitized financing. On December 22, 2021, PNM filed a Notice of Appeal with the NM Supreme Court of the NMPRC decision to deny the application and on July 6, 2023, the NM Supreme Court affirmed the NMPRC decision concluding that the NMPRC reasonably and lawfully denied PNM’s application for abandonment. As a result of the NM Supreme Court's decision to uphold the NMPRC's denial, the Consolidated Statements of Earnings for the year ended December 31, 2023 reflect a regulatory disallowance of $3.7 million. On April 23, 2024, PNM filed an interim notice informing the NMPRC that PNM’s updated analysis indicates it is in the interest of customers for PNM to remain as a participant in Four Corners until the expiration of the current coal supply agreement in 2031. In August 2024, PNM and NTEC terminated the Four Corners Purchase and Sale Agreement and executed an agreement for the reimbursement of PNM’s initial $15.0 million payment with interest, which was paid in 2024.

2026 Resource Application

On October 25, 2023, PNM filed an application with the NMPRC seeking approval of resources to be available for the 2026 summer peak. The application included a request for approval of a 100 MW solar PPA and three ESAs of 100 MW, 100 MW, and 50 MW. In addition, PNM was seeking approval of a CCN for a 60 MW battery to be owned by PNM. The resources were deemed necessary for PNM to safely and reliably meet its projected system load. A hearing was held on March 20 and 21, 2024. On May 3, 2024, the hearing examiner in the case issued a RD approving PNM’s requested resources. On May 30, 2024, the NMPRC approved the RD in its entirety. On July 9, 2024, a group of New Mexico legislators filed a petition with the NM Supreme Court requesting the court grant their motion for rehearing, which was denied on September 3, 2024. This matter is now concluded.

2028 Resource Application

On November 22, 2024, PNM filed an application with the NMPRC seeking approval of ESAs, a PPA, and a CCN for system resources in 2028 to be available to meet summer 2028 customer needs. PNM is requesting approval of:

•Two 150 MW ESAs

•A 167 MW PPA for the Valencia power plant through 2039

•A CCN for a 100 MW solar facility and a 30 MW battery to be PNM-owned and located in San Juan County. The request provides the opportunity to increase the 30 MW battery by an additional 20 MW

A hearing will be held beginning April 2, 2025, if needed.

Grid Modernization Plan

On October 3, 2022, in compliance with New Mexico Grid Modernization Statute, PNM filed its Grid Modernization Application with the NMPRC. The projects included in the Grid Modernization Application improve customers’ ability to customize their use of energy and ensure that customers, including low-income customers, are a top priority and will benefit consistent with the Grid Modernization Statute. PNM’s proposal to modernize its electricity grid through infrastructure and technology improvements also increases the efficiency, reliability, resilience, and security of PNM’s electric system. PNM’s application seeks approval of grid modernization investments of approximately $344 million for the first six years of a broader 11-year strategy. The proposed Grid Modernization Rider would recover capital costs, operating expenses, and taxes associated

with the investments included in the Grid Modernization Application. PNM also requested authorization to create related regulatory assets and liabilities, permitting PNM to record costs incurred for the development and implementation of PNM’s plan between the requested approval of the application on July 1, 2023, and the implementation of the Grid Modernization Rider by September 1, 2023; undepreciated investments associated with legacy meters being replaced with AMI meters; and over- or under-collection of costs through the Grid Modernization Rider. In addition, PNM requested approval of the proposed format of an Opt-Out Consent Form and proposed opt-out fees, which includes a one-time fee and a monthly fee. Following a hearing and subsequent briefs, on May 31, 2023, the NMPRC issued an order requiring the hearing examiner to direct PNM to file a cost benefit analysis as a supplement to the application. On November 22, 2023, PNM filed the required cost benefit analysis supporting PNM’s proposed Grid Modernization plan. A hearing was held in April 2024 and post-hearing briefs and response briefs were filed in June 2024. On August 16, 2024, the hearing examiner in the case issued a RD. The RD largely approved PNM’s application with minor modifications, including limiting to a return of its undepreciated costs of legacy meters and conditioned approval upon PNM accelerating the deployment schedule following a final order. On October 17, 2024, the NMPRC issued a final order adopting the RD but removed the accelerated deployment schedule.

The Community Solar Act

In 2021, the Community Solar Act established a program that allows for the development of community solar facilities and provides customers of a qualifying utility with the option of subscribing to community solar facilities, and in exchange would receive a bill credit from their utility, while the utility received energy from the community solar facility. The NMPRC was charged with administering the Community Solar Act program, establishing a total maximum capacity of 200 MW community solar facilities and allocating proportionally to the New Mexico electric investor-owned utilities and participating cooperatives, of which PNM was allocated 125 MW. On October 3, 2024, the NMPRC issued an order raising the total maximum capacity of community solar facilities by 300 MW, of which PNM was allocated 185 MW.

In 2022, PNM filed its initial Community Solar tariff and subsequently filed an updated Community Solar tariff under protest and filed a motion for clarification, suspension, and timely hearing on PNM’s Community Solar tariff. In 2023, the NMPRC suspended PNM’s Community Solar tariff and issued an order opening a new docket for two-phase proceedings. The first phase addressed issues concerning the proposed subscriber organization agreements and the proposed customer data forms. The second phase addressed all issues concerning proposed tariffs, agreements and forms that were not addressed in the first phase. In 2023, the NMPRC issued an order approving an uncontested stipulation on the first phase and PNM’s advice notice conforming to the stipulation became effective. A hearing for the second phase was held from January 17 through January 19, 2024. On August 30, 2024, the hearing examiner issued a RD, that recommended rejecting PNM’s proposed community solar rider and required PNM to refile the rider, approval of an accounting order to track certain costs in a regulatory asset and included recommendations for various issues to be handled in a future rulemaking. On November 26, 2024, the NMPRC issued an order rejecting substantially all tariffs, agreements and forms, requiring PNM to file new proposed tariffs, in addition to adopting a majority of other components proposed in the RD. PNM filed revised tariffs on February 21, 2025. PNM cannot predict the outcome of the pending matters.

FERC Compliance

PNM conducted a comprehensive internal review of its filings with FERC regarding the potential timely filing of certain agreements that contained deviations from PNM’s standard form of service agreement in its OATT and assessing any applicable FERC waivers or refund requirements. Upon completion of the comprehensive review, PNM identified service agreements containing provisions that do not conform to the standard form of agreement on file with FERC. On March 18 and March 21, 2022, PNM filed applications with FERC requesting acceptance of certain agreements as well as rejection of other service agreements and further requesting that FERC not assess time-value refunds on the accepted agreements. On May 17, 2022, FERC issued two delegated letter orders accepting the service agreements and requiring PNM to pay the time-value refunds on the revenues it received on unaffiliated, late-filed, service agreements which contained language alleged to be non-conforming.

On November 21, 2022, FERC issued an order on rehearing that required PNM to pay its customers approximately $8.1 million in time-value refunds. On November 28, 2022, PNM filed an unopposed motion for voluntary dismissal with the United States Court of Appeals for the District of Columbia of its petitions for review, which was granted on December 22, 2022. In the fourth quarter of 2022, PNM made payments totaling $8.1 million to customers which were recorded as a reduction to electric operating revenues on the Consolidated Statements of Earnings. This matter is now concluded.

FERC Order 864

In November 2019, FERC issued Order No. 864, which required public utility transmission providers with transmission formula rates to revise those rates to account for changes resulting from the Tax Cuts and Jobs Act of 2017 (the “Tax Act”). PNM had already made revisions to its formula rate to account for Tax Act changes, and, as a result of the Order, PNM proposed additional changes to its formula rate to implement the remaining requirements of the Order. In July 2022, FERC issued an order finding that PNM had predominantly complied with the requirements but set aside certain matters for settlement and hearing procedures.

On November 22, 2023, PNM, on behalf of the settling parties, filed a settlement agreement with FERC resolving all issues. As a result of the settlement agreement, PNM recorded a decrease of $3.2 million to electric operating revenues and an increase to interest charges of $0.3 million on the Consolidated Statement of Earnings and an increase to other current liabilities of $3.5 million on the Consolidated Balance Sheets as of and for the year ended December 31, 2023. This matter is now concluded.

Transportation and Electrification Program (TEP)

On June 1, 2023, PNM filed its 2024-2026 TEP with the NMPRC, requesting approval of a $37.1 million total three-year budget and continuation of the current TEP Rider. Approximately 22% of the budget, $8.0 million, will be dedicated to low-income customers. On February 2, 2024, the hearing examiners in the case issued a RD largely approving PNM’s 2024 Plan but with modifications to certain TEP programs. On February 23, 2024, the NMPRC approved the RD with additional modifications that reduced the three-year budget by $4.0 million, for a total revised budget of $32.9 million. The TEP rider became effective on April 26, 2024.

TNMP recovers the costs of its energy efficiency programs through an energy efficiency cost recovery factor (“EECRF”), which includes projected program costs, under or over collected costs from prior years, rate case expenses, and performance bonuses (if the programs exceed mandated savings goals).

The following sets forth TNMP’s EECRF increases:


Effective Date	Aggregate Collection Amount		Performance Bonus
	(In millions)






March 1, 2022	$	7.2	$	2.3
March 1, 2023	7.3		1.9
March 1, 2024	6.6		1.2

On May 31, 2024, TNMP filed its request to adjust the EECRF to reflect changes in costs for 2025. On October 24, 2024, the PUCT approved the total amount requested, authorizing recovery of $7.0 million, including a performance bonus of $1.3 million based on TNMP’s energy efficiency achievements in the 2023 plan year.

Transmission Cost of Service Rates

TNMP can update its TCOS rates twice per year to reflect changes in its invested capital although updates are not allowed while a general rate case is in process. Updated rates reflect the addition and retirement of transmission facilities, including appropriate depreciation, federal income tax and other associated taxes, and the approved rate of return on such facilities.

The following sets forth TNMP’s recent interim transmission cost rate increases:


Effective Date	Approved Increase in Rate Base		Annual Increase in Revenue
	(In millions)














March 25, 2022	$	95.6	$	14.2
September 22, 2022	36.0		5.3
May 12, 2023	150.5		19.4
September 6, 2023	21.4		4.2
March 15, 2024	97.4		13.1
September 20, 2024	20.6		3.9

On January 24, 2025, TNMP filed an application to further update its transmission rates, which would increase revenues by $11.5 million annually, based on an increase in rate base of $83.5 million. The application is pending before the PUCT.

Periodic Distribution Rate Adjustment

PUCT rules permit interim rate adjustments to reflect changes in investments in distribution assets. Historically, distribution utilities have been restricted to a single, annual periodic rate adjustment through a DCRF submitted between April 1 and April 8 of each year as long as the electric utility was not earning more than its authorized rate of return using weather-normalized data. However, the recent passage of Senate Bill 1015 now permits DCRF proceedings to be filed twice per year with a 60-day administrative deadline that can be extended for 15 days on good cause. Additionally, a DCRF may be filed during a pending rate case proceeding as long as that DCRF request is not filed until the 185th day after the rate case proceeding was initiated. The following sets forth TNMP’s recent interim distribution rate increases:


Effective Date	Approved Increase in Rate Base		Annual Increase in Revenue
	(In millions)















September 1, 2022	$	95.7	$	6.8
September 1, 2023	157.0		14.5
July 28, 2024	205.9		15.6
November 17, 2024	43.7		7.7

3G Meters Notice of Violation

In 2020, the PUCT established the COVID-19 Electricity Relief Program for electric utilities, REPs, and customers impacted by COVID-19. The program allowed providers to implement a rider to collect unpaid residential retail customer bills and to establish a regulatory asset for costs related to COVID-19. These costs included but were not limited to costs related to unpaid accounts.

In December 2023, TNMP and the PUCT reached a settlement agreement related to a notice of violation against TNMP primarily for estimating 3G meters during the period that TNMP was remediating the meters. TNMP maintained that the remediation efforts were impacted by supply chain and labor availability issues resulting from COVID-19. Pursuant to the settlement agreement, TNMP agreed to no longer pursue the recovery of COVID-19 related costs that were recorded as a regulatory asset. This resulted in a regulatory disallowance of $1.2 million recorded for the year ended December 31, 2023.

Hurricane Beryl

On July 8, 2024, Hurricane Beryl made landfall in the Texas Gulf Coast leaving approximately 116,000 customers in the TNMP service area without power. As of December 31, 2024, TNMP incurred $53.1 million of costs, of which $32.1 million has been recorded in Utility Plant and $21.0 million has been recorded as a regulatory asset. TNMP will continue to track storm-related restoration costs to seek collection of such costs in a future regulatory proceeding.

System Resiliency Plan (“SRP”)

In 2023, the Texas Legislature enacted House Bill No, 2555 (“HB 2555”), permitting an electric utility to seek approval of, and cost recovery for, a system resiliency plan. On August 28, 2024, TNMP filed its first SRP with the PUCT designed to benefit customers through enhanced resiliency of its distribution system, as intended under HB 2555. The SRP includes approximately $600 million of capital investments and approximately $151 million of other related costs over three years and was developed using a comprehensive and data-driven approach which evaluated various types of resiliency events posing material risk to the safe and reliable operation of TNMP's distribution system. TNMP's service territory includes non-contiguous areas across different regions of Texas, ranging from small communities and rural areas to communities around large metropolitan areas, each with unique risks. Investments in the SRP are prioritized based on customer benefit, physical protection of infrastructure, foundational investments in operational and cybersecurity technologies, and wildfire risk reduction and are focused on lower-performing areas in the context of reliability. Eight different resiliency measures are outlined in the SRP with associated programs and infrastructure impacts to improve the system's ability to prevent, withstand, mitigate and/or more promptly recover from resiliency events: distribution system resiliency, distribution system protection modernization, vegetation management, wildfire mitigation, flood mitigation, enhanced operations system technology, cybersecurity, and physical security resiliency. The SRP is subject to PUCT approval over 180 days as stated in Texas legislation. Recovery of investments and costs are permissible primarily through semi-annual DCRF filings, with deferral of depreciation and other certain expenses until recovery begins.

On December 11, 2024, TNMP filed an unopposed settlement with the PUCT. The settlement includes $565.8 million of capital investments over 2025 through 2027, reflecting 94% of TNMP’s proposed plan investments. The settlement also encompasses $128.2 million of operations and maintenance expenses associated with several programs, including vegetation management and wildfire mitigation.
