Accounting Policies [Abstract] | |
Summary of the Business and Significant Accounting Policies | Summary of the Business and Significant Accounting Policies Nature of Business PNMR is an investor-owned holding company with two regulated utilities providing electricity and electric services in New Mexico and Texas. PNMR’s primary subsidiaries are PNM and TNMP. PNM is a public utility with regulated operations primarily engaged in the generation, transmission, and distribution of electricity. TNMP is a wholly-owned subsidiary of TNP, which is a holding company that is wholly-owned by PNMR. TNMP provides regulated transmission and distribution services in Texas. PNMR’s common stock trades on the New York Stock Exchange under the symbol PNM. Financial Statement Preparation and Presentation The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could ultimately differ from those estimated. The Notes to Consolidated Financial Statements include disclosures for PNMR, PNM, and TNMP. This report uses the term “Company” when discussing matters of common applicability to PNMR, PNM, and TNMP. Discussions regarding only PNMR, PNM, or TNMP are so indicated. Certain amounts in the 2018 and 2017 Consolidated Financial Statements and Notes thereto have been reclassified to conform to the 2019 financial statement presentation. GAAP defines subsequent events as events or transactions that occur after the balance sheet date but before financial statements are issued or are available to be issued. Based on their nature, magnitude, and timing, certain subsequent events may be required to be reflected at the balance sheet date and/or required to be disclosed in the financial statements. The Company has evaluated subsequent events as required by GAAP. Principles of Consolidation The Consolidated Financial Statements of each of PNMR, PNM, and TNMP include their accounts and those of subsidiaries in which that entity owns a majority voting interest. PNM also consolidates Valencia (Note 10). PNM owns undivided interests in several jointly-owned power plants and records its pro-rata share of the assets, liabilities, and expenses for those plants. The agreements for the jointly-owned plants provide that if an owner were to default on its payment obligations, the non-defaulting owners would be responsible for their proportionate share of the obligations of the defaulting owner. In exchange, the non-defaulting owners would be entitled to their proportionate share of the generating capacity of the defaulting owner. There have been no such payment defaults under any of the agreements for the jointly-owned plants. PNMR shared services’ expenses, which represent costs that are primarily driven by corporate level activities, are charged to the business segments. These services are billed at cost and are reflected as general and administrative expenses in the business segments. Other significant intercompany transactions between PNMR, PNM, and TNMP include interest and income tax sharing payments, as well as equity transactions, and interconnection billings. All intercompany transactions and balances have been eliminated. See Note 20. Accounting for the Effects of Certain Types of Regulation The Company maintains its accounting records in accordance with the uniform system of accounts prescribed by FERC and adopted by the NMPRC and PUCT. Certain of the Company’s operations are regulated by the NMPRC, PUCT, and FERC and the provisions of GAAP for rate-regulated enterprises are applied to the regulated operations. Regulators may assign costs to accounting periods that differ from accounting methods applied by non-regulated utilities. When it is probable that regulators will permit recovery of costs through future rates, costs are deferred as regulatory assets that otherwise would be expensed. Likewise, regulatory liabilities are recognized when it is probable that regulators will require refunds through future rates or when revenue is collected for expenditures that have not yet been incurred. GAAP also provides for the recognition of revenue and regulatory assets and liabilities associated with “alternative revenue programs” authorized by regulators. Such programs allow the utility to adjust future rates in response to past activities or completed events, if certain criteria are met, even for programs that do not otherwise qualify for recognition of regulatory assets and liabilities. Regulatory assets and liabilities are amortized into earnings over the authorized recovery period. Accordingly, the Company has deferred certain costs and recorded certain liabilities pursuant to the rate actions of the NMPRC, PUCT, and FERC. Information on regulatory assets and regulatory liabilities is contained in Note 13. In some circumstances, regulators allow a requested increase in rates to be implemented, subject to refund, before the regulatory process has been completed and a decision rendered by the regulator. When this occurs, the Company assesses the possible outcomes of the rate proceeding. The Company records a provision for refund to the extent the amounts being collected, subject to refund, exceed the amount the Company determines is probable of ultimately being allowed by the regulator. Cash and Restricted Cash Investments in highly liquid investments with original maturities of three months or less at the date of purchase are considered cash and cash equivalents. As of January 1, 2017, PNM held a deposit of $1.0 million from a third party that was restricted for PNM’s construction of transmission interconnection facilities and was held as restricted cash until the second quarter of 2017, at which time a refund was made to the third party. Under the terms of the BTMU Term Loan agreement (Note 7), all cash of NM Capital was restricted to be used for payments required under that agreement or for taxes and fees. On May 22, 2018, Westmoreland repaid the Westmoreland Loan in full. NM Capital used a portion of the proceeds to repay all of its obligations under the BTMU Term Loan. These payments effectively terminated the loan agreements (Note 10). Utility Plant Utility plant is stated at original cost and includes capitalized payroll-related costs such as taxes, pension, other fringe benefits, administrative costs, and AFUDC, where authorized by rate regulation, or capitalized interest. Repairs, including major maintenance activities, and minor replacements of property are expensed when incurred, except as required by regulators for ratemaking purposes. Major replacements are charged to utility plant. Gains, losses, and costs to remove resulting from retirements or other dispositions of regulated property in the normal course of business are credited or charged to accumulated depreciation. PNM and TNMP may receive reimbursements, referred to as CIAC, from customers to pay for all or part of certain construction projects to the extent the project does not benefit regulated customers in general. PNM and TNMP account for these reimbursements as offsets to utility plant additions based on the requirements of the NMPRC, FERC, and PUCT. Due to the PUCT’s regulatory treatment of CIAC reimbursements, TNMP also receives a financing component that is recognized as other income on the Consolidated Statements of Earnings. Under the NMPRC regulatory treatment, PNM typically does not receive a financing component. Depreciation and Amortization PNM’s provision for depreciation and amortization of utility plant, other than nuclear fuel, is based upon straight-line rates approved by the NMPRC and FERC. Amortization of nuclear fuel is based on units-of-production. TNMP’s provision for depreciation and amortization of utility plant is based upon straight-line rates approved by the PUCT. Depreciation of non-utility property is computed based on the straight-line method. The provision for depreciation of certain equipment is allocated between operating expenses and construction projects based on the use of the equipment. Average straight-line rates used were as follows: Year ended December 31, 2019 2018 2017 PNM Electric plant 2.47 % 2.40 % 2.52 % Common, intangible, and general plant 7.91 % 8.18 % 8.36 % TNMP 4.04 % 3.49 % 3.57 % Allowance for Funds Used During Construction As provided by the FERC uniform systems of accounts, AFUDC is charged to regulated utility plant for construction projects. This allowance is designed to enable a utility to capitalize financing costs during periods of construction of property subject to rate regulation. It represents the cost of borrowed funds (allowance for borrowed funds used during construction or “debt AFUDC”) and a return on other funds (allowance for equity funds used during construction or “equity AFUDC”). The debt AFUDC is recorded in interest charges and the equity AFUDC is recorded in other income on the Consolidated Statements of Earnings. For the years ended December 31, 2019 , 2018 , and 2017 , PNM recorded $5.0 million , $6.1 million , and $6.3 million of debt AFUDC at annual rates of 2.99% , 3.19% , and 3.14% and $6.7 million , $8.2 million , and $8.7 million of equity AFUDC at annual rates of 3.95% , 4.25% , and 4.30% . For the years ended December 31, 2019, 2018, and 2017, TNMP recorded $2.4 million , $2.3 million , and $1.2 million of debt AFUDC at rates of 3.23% , 3.32% , and 3.17% and $2.8 million , $2.2 million , and $0.9 million of equity AFUDC at rates of 3.78% , 3.29% , and 2.29% . Materials, Supplies, and Fuel Stock Materials and supplies relate to transmission, distribution, and generating assets. Materials and supplies are charged to inventory when purchased and are expensed or capitalized as appropriate when issued. Materials and supplies are valued using an average costing method. Coal is valued using a rolling weighted average costing method that is updated based on the current period cost per ton. Periodic aerial surveys are performed on the coal piles and adjustments are made. Average cost is equal to net realizable value under the ratemaking process. Inventories consisted of the following at December 31 : PNMR PNM TNMP 2019 2018 2019 2018 2019 2018 (In thousands) Coal $ 24,914 $ 22,777 $ 24,914 $ 22,777 $ — $ — Materials and supplies 53,015 49,057 47,311 44,320 5,704 4,737 $ 77,929 $ 71,834 $ 72,225 $ 67,097 $ 5,704 $ 4,737 Investments PNM holds investment securities in the NDT for the purpose of funding its share of the decommissioning costs of PVNGS and trusts for PNM’s share of final reclamation costs related to the coal mines serving SJGS and Four Corners (Note 16). Since third party investment managers have sole discretion over the purchase and sale of the securities, PNM records a realized loss as an impairment for any available-for-sale debt security that has a market value that is less than cost at the end of each quarter. Prior to 2018, PNM classified all debt and equity investments in the NDT and coal mine reclamation trusts as available-for-sale securities. Effective January 1, 2018, the Company adopted Accounting Standards Update 2016-01 – Financial Instruments (Subtopic 825-10), which eliminates the requirement to classify investments in equity securities with readily determinable fair values into trading or available-for-sale categories and requires those equity securities to be measured at fair value with changes in fair value recognized in earnings rather than in OCI. On January 1, 2018, PNM recorded a cumulative effect adjustment to reclassify unrealized holding gains on equity securities held in the NDT and coal mine reclamation trusts from AOCI to retained earnings on the Consolidated Balance Sheets. Accordingly, the information for investment securities in the NDT and coal mine reclamation trusts for 2019 and 2018 is presented under ASU 2016-01 and the information for 2017 is presented under prior GAAP. For the years ended December 31, 2019 and 2018, PNM recorded impairment losses on the available-for-sale debt securities of $5.7 million and $13.7 million . For the year ended December 31, 2017, PNM recorded impairment losses on the available-for-sale securities, which included both debt and equity securities, of $7.1 million . No gains or losses are deferred as regulatory assets or liabilities. See Notes 3 and 9. All investments are held in PNM’s name and are in the custody of major financial institutions. The specific identification method is used to determine the cost of securities disposed of, with realized gains and losses reflected in other income and deductions. Investment in NM Renewable Development, LLC On September 22, 2017, PNMR Development and AEP OnSite Partners created NMRD to pursue the acquisition, development, and ownership of renewable energy generation projects, primarily in the state of New Mexico. PNMR Development and AEP OnSite Partners each have a 50% ownership interest in NMRD. In December 2017, PNMR Development made a contribution to NMRD of its interest in three 10 MW solar facilities it was constructing and assigned its interests in several agreements related to those facilities to NMRD. The facilities had a book value of $24.8 million , which approximated fair value at that time. AEP OnSite Partners made a cash contribution to NMRD equal to 50% of the value of the 30 MW solar capacity, amounting to $12.4 million , which cash was then distributed from NMRD to PNMR Development. During 2019, 2018, and 2017 PNMR Development and AEP OnSite Partners each made cash contributions of $38.3 million , $9.0 million , and $4.1 million to NMRD for its construction activities. At December 31, 2019 , NMRD’s renewable energy capacity in operation is 85.1 MW, which includes 80 MW of solar-PV facilities to supply energy to the Facebook data center located within PNM’s service territory, 1.9 MW to supply energy to Columbus Electric Cooperative located in southwest New Mexico, 2.0 MW to supply energy to the Central New Mexico Electric Cooperative, and 1.2 MW of solar-PV facilities to supply energy to the City of Rio Rancho, New Mexico. PNMR accounts for its investment in NMRD using the equity method of accounting because PNMR’s ownership interest results in significant influence, but not control, over NMRD and its operations. PNMR records as income its percentage share of earnings or loss of NMRD and carries its investment at cost, adjusted for its share of undistributed earnings or losses. PNMR presents its share of net earnings from NMRD in other income on the Consolidated Statements of Earnings. For the year ended December 31, 2017, NMRD revenues, expenses, and net income were each less than $0.1 million . Summarized financial information for NMRD is as follows: Results of Operations December 31, 2019 2018 (In thousands) Operating revenues $ 3,662 $ 3,147 Operating expenses 2,971 2,136 Net earnings $ 691 $ 1,011 Financial Position December 31, 2019 2018 (In thousands) Current assets $ 7,187 $ 2,581 Net property, plant, and equipment 132,772 50,784 Total assets 139,959 53,365 Current liabilities 9,640 237 Owners’ equity $ 130,319 $ 53,128 Goodwill Under GAAP, the Company does not amortize goodwill. Goodwill is evaluated for impairment annually, or more frequently if events and circumstances indicate that the goodwill might be impaired. See Note 19. Asset Impairment Tangible long-lived assets and right-of-use assets associated with leases are evaluated in relation to the estimated future undiscounted cash flows to assess recoverability when events and circumstances indicate that the assets might be impaired. See Note 16. Revenue Recognition See Note 4 for a discussion of electric operating revenues. Accounts Receivable and Allowance for Uncollectible Accounts Accounts receivable consists primarily of trade receivables from customers. In the normal course of business, credit is extended to customers on a short-term basis. The Company calculates the allowance for uncollectible accounts based on historical experience and estimated default rates. The accounts receivable balances are reviewed monthly and adjustments to the allowance for uncollectible accounts and bad debt expense are made as necessary. Amounts that are deemed uncollectible are written off. Amortization of Debt Acquisition Costs Discount, premium, and expense related to the issuance of long-term debt are amortized over the lives of the respective issues. Gains and losses incurred upon the early retirement of long-term debt are recognized in other income or other deductions, except for amounts recoverable through NMPRC, FERC, or PUCT regulation, which are recorded as regulatory assets or liabilities and amortized over the lives of the respective issues. Unamortized premium, discount, and expense related to long-term debt are reflected as part of the related liability on the Consolidated Balance Sheets. Derivatives The Company records derivative instruments, including energy contracts, on the balance sheet as either an asset or liability measured at their fair value. GAAP requires that changes in the derivatives’ fair value be recognized currently in earnings unless specific hedge accounting criteria are met. PNM also records certain commodity derivative transactions recoverable through NMPRC regulation as regulatory assets or liabilities. See Note 7 and Note 9. The Company treats all forward commodity purchases and sales contracts subject to unplanned netting or “book-out” by the transmission provider as derivative instruments subject to mark-to-market accounting. GAAP provides guidance on whether realized gains and losses on derivative contracts not held for trading purposes should be reported on a net or gross basis and concludes such classification is a matter of judgment that depends on the relevant facts and circumstances. See Note 4. Decommissioning and Reclamation Costs In accordance with GAAP, PNM is only required to recognize and measure decommissioning liabilities for tangible long-lived assets for which a legal obligation exists. Nuclear decommissioning costs and related accruals are based on periodic site-specific estimates of the costs for removing all radioactive and other structures at PVNGS and are dependent upon numerous assumptions, including estimates of future decommissioning costs at current price levels, inflation rates, and discount rates. PNM’s accruals for PVNGS Units 1, 2, and 3, including portions held under leases, have been made based on such estimates, the guidelines of the NRC, and the PVNGS license periods. PVNGS Units 1 and 2 are included in PNM’s retail rates and PVNGS Unit 3 was excluded through December 31, 2017 but is included in retail rates beginning in 2018. See Note 16. See Note 17 for information concerning the treatment of nuclear decommissioning costs for certain purchased and leased portions of PVNGS in the NMPRC’s order in PNM’s NM 2015 Rate Case and the NM Supreme Court’s decision on PNM’s appeal of that order. In connection with both the SJGS and Four Corners coal supply agreements, the owners are required to reimburse the mining companies for the cost of contemporaneous reclamation, as well as the costs for final reclamation of the coal mines. The reclamation costs are based on periodic site-specific studies that estimate the costs to be incurred in the future and are dependent upon numerous assumptions, including estimates of future reclamation costs at current price levels, inflation rates, and discount rates. PNM considers the contemporaneous reclamation costs part of the cost of its delivered coal costs. See Note 16 for a discussion of reclamation costs. Environmental Costs The normal operations of the Company involve activities and substances that expose the Company to potential liabilities under laws and regulations protecting the environment. Liabilities under these laws and regulations can be material and may be imposed without regard to fault, or may be imposed for past acts, even though the past acts may have been lawful at the time they occurred. The Company records its environmental liabilities when site assessments or remedial actions are probable and a range of reasonably likely cleanup costs can be estimated. The Company reviews its sites and measures the liability by assessing a range of reasonably likely costs for each identified site using currently available information and the probable level of involvement and financial condition of other potentially responsible parties. These estimates are based on assumptions regarding the costs for site investigations, remediation, operations and maintenance, monitoring, and site closure. The ultimate cost to clean up the Company’s identified sites may vary from its recorded liability due to numerous uncertainties inherent in the estimation process. Amounts recorded for environmental expense in the years ended December 31, 2019 , 2018 , and 2017 , as well as the amounts of environmental liabilities at December 31, 2019 and 2018 were insignificant. Pension and Other Postretirement Benefits See Note 11 for a discussion of pension and postretirement benefits expense, including a discussion of the actuarial assumptions. Stock-Based Compensation See Note 12 for a discussion of stock-based compensation expense. Income Taxes Income taxes are recognized using the asset and liability method of accounting for income taxes. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying value of existing assets and liabilities and their respective tax basis. In accordance with GAAP, all deferred taxes are reflected as non-current on the Consolidated Balance Sheets. Current NMPRC, FERC, and PUCT approved rates include the tax effects of the majority of these differences. GAAP requires that rate-regulated enterprises record deferred income taxes for temporary differences accorded flow-through treatment at the direction of a regulatory commission. The resulting deferred tax assets and liabilities are recorded based on the expected cash flow to be reflected in future rates. Because the NMPRC, FERC, and the PUCT have consistently permitted the recovery of tax effects previously flowed-through earnings, the Company has established regulatory assets and liabilities offsetting such deferred tax assets and liabilities. The Company recognizes only the impact of tax positions that, based on their merits, are more likely than not to be sustained upon an IRS audit. The Company defers investment tax credits and amortizes them over the estimated useful lives of the assets. See Note 18 for additional information, including a discussion of the impacts of the Tax Act. The Company makes an estimate of its anticipated effective tax rate for the year as of the end of each quarterly period within its fiscal year. In interim periods, income tax expense is calculated by applying the anticipated annual effective tax rate to year-to-date earnings before taxes, which includes the earnings attributable to the Valencia non-controlling interest. GAAP also provides that certain unusual or infrequently occurring items, as well as adjustments due to enactment of new tax laws, be excluded from the estimated annual effective tax rate calculation. Lease Commitments See Note 13 for a discussion of lease commitments. New Accounting Pronouncements Information concerning recently issued accounting pronouncements that have not been adopted by the Company is presented below. The Company does not expect difficulty in adopting these standards by their required effective dates. Accounting Standards Update 2016-13 – Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments In June 2016, the FASB issued ASU 2016-13, which changes the way entities recognize impairment of many financial assets, including accounts receivable and investments in certain debt securities, by requiring immediate recognition of estimated credit losses expected to occur over the remaining lives of the assets. In November 2018, the FASB clarified that receivables arising from operating leases are not within the scope of Topic 326 for assets measured at amortized costs. Instead, impairments of receivables arising from operating leases should be accounted for in accordance with Topic 842. In May 2019, the FASB issued transition relief by providing an option to irrevocably elect the fair value option for certain financial assets previously measured at amortized cost. The Company is in the process of analyzing the impacts of the new standard but does not anticipate a significant impact on its reserves for trade receivables or on PNMR’s guarantees of certain PNMR Development debt arrangements. A cumulative effect adjustment is also not anticipated upon implementation. ASU 2016-13 also requires entities to separately measure and realize an impairment for credit losses on available-for-sale debt securities for which carrying value exceeds fair value, unless such securities have been determined to be other than temporarily impaired and the entire decrease in value has been realized as an impairment. PNM records a realized loss as an impairment for any available-for-sale debt security that has a fair value that is less than carrying value at the end of each quarter. As a result, the Company does not anticipate the new standard will impact its accounting for available-for-sale debt securities. The Company will adopt ASU 2016-13 as of January 1, 2020, its required effective date. Accounting Standards Update 2017-04 – Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment In January 2017, the FASB issued ASU 2017-04 to simplify the annual goodwill impairment assessment process. Currently, the first step of a quantitative impairment test requires an entity to compare the fair value of each reporting unit containing goodwill with its carrying value (including goodwill). If as a result of this analysis, the entity concludes there is an indication of impairment in a reporting unit having goodwill, the entity is required to perform the second step of the impairment analysis, determining the amount of goodwill impairment to be recorded. The amount is calculated by comparing the implied fair value of the goodwill to its carrying amount. This exercise requires the entity to allocate the fair value determined in step one to the individual assets and liabilities of the reporting unit. Any remaining fair value would be the implied fair value of goodwill on the testing date. To the extent the recorded amount of goodwill of a reporting unit exceeds the implied fair value determined in step two, an impairment loss would be reflected in results of operations. ASU 2017-04 eliminates the second step of the impairment analysis. Accordingly, if the first step of a quantitative goodwill impairment analysis performed after adoption of ASU 2017-04 indicates that the fair value of a reporting unit is less than its carrying value, the goodwill of that reporting unit would be impaired to the extent of that difference. The Company will adopt ASU 2017-04 for impairment testing after January 1, 2020, its required effective date. Accounting Standards Update 2018-13 – Fair Value Measurements (Topic 820) Disclosure Framework: Changes to the Disclosure Requirements for Fair Value Measurements In August 2018, the FASB issued ASU 2018-13 to improve fair value disclosures. ASU 2018-13 eliminates certain disclosure requirements related to transfers between Levels 1 and 2 of the fair value hierarchy and the requirement to disclose the valuation process for Level 3 fair value measurements. ASU 2018-13 also amends certain disclosure requirements for investments measured at net asset value and requires new disclosures for Level 3 investments, including a new requirement to disclose changes in unrealized gains or losses recorded in OCI related to Level 3 fair value measurements. ASU 2018-13 is effective for the Company beginning on January 1, 2020 and permits entities to adopt all or certain elements of the new guidance prior to its effective date. ASU 2018-13 requires retrospective application, except for the new disclosures related to Level 3 investments which are to be applied prospectively. As discussed in Note 9, PNM and TNMP have investment securities in trusts for decommissioning, reclamation, pension benefits, and other postretirement benefits, which are measured at fair value. Certain investments in these trusts are measured at net asset value per share. These trusts currently hold no Level 3 investments. The Company is evaluating the requirements of ASU 2018-13, but does not anticipate it will have a significant impact on the Company’s fair value disclosures. Accounting Standards Update 2018-14 – Compensation - Retirement Benefits - Defined Benefit Plans (Topic 715) Disclosure Framework: Changes to the Disclosure Requirements for Defined Benefit Plans In August 2018, the FASB issued ASU 2018-14 to improve benefit plan sponsors’ disclosures for defined benefit pension and other post-employment benefit plans. ASU 2018-14 removes the requirement to disclose the amounts in other comprehensive income expected to be recognized as benefit cost over the next fiscal year and the requirement to disclose the impact of a one-percentage-point change in the assumed health care cost trend rate; clarifies the disclosure requirements for plans with assets that are less than their projected benefit, or accumulated benefit obligation; and requires significant gains and losses affecting benefit obligations during the period be disclosed. ASU 2018-14 is effective for the Company on December 31, 2020, although early adoption is permitted, and requires retrospective application. As discussed in Note 11, PNM and TNMP maintain qualified defined benefit, other postretirement benefit plans providing medical and dental benefits, and executive retirement programs. The Company is in the process of evaluating the requirements of ASU 2018-14 but does not anticipate these changes will have a significant impact on the Company’s defined benefit and other postretirement benefit plan disclosures. Accounting Standards Update 2018-15 – Intangibles - Goodwill and Other - Internal Use Software (Topic 350): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract In August 2018, the FASB issued ASU 2018-15 to align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for implementation costs incurred to develop or obtain internal-use software. Under ASU 2018-15, entities are required to capitalize implementation costs for hosting arrangements if those costs meet the capitalization requirements for internal-use software arrangements. ASU 2018-15 requires entities to present cash flows, capitalized costs, and amortization expense in the same financial statement line items as other costs incurred for such hosting arrangements. ASU 2018-15 is effective for the Company on January 1, 2020 and allows entities to apply the new requirements retrospectively or prospectively. The Company is in the process of analyzing the impacts of this new standard. Accounting Standards Update 2019-12 – Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes In December 2019, the FASB issued ASU 2019-12 as part of its initiative to reduce complexity in accounting standards. The amendments in ASU 2019-12 simplify accounting for income taxes by removing several accounting exceptions to accounting for income taxes. ASU 2019-12 also eliminates or simplifies other income tax accounting requirements, including a requirement that entities recognize franchise tax (or similar tax) that is partially based on income as an income-based tax. ASU 2019-12 is effective for the Company beginning on January 1, 2021 and allows for early adoption. ASU 2019-12 is to be applied prospectively or retrospectively in the period of adoption depending on the type of amendment. The Company is in the process of analyzing the impacts of this new standard. |

Segment Reporting [Abstract] | |
Segment Information | Segment Information The following segment presentation is based on the methodology that management uses for making operating decisions and assessing performance of its various business activities. A reconciliation of the segment presentation to the GAAP financial statements is provided. PNM PNM includes the retail electric utility operations of PNM that are subject to traditional rate regulation by the NMPRC. PNM provides integrated electricity services that include the generation, transmission, and distribution of electricity for retail electric customers in New Mexico. PNM also includes the generation and sale of electricity into the wholesale market, as well as providing transmission services to third parties. The sale of electricity includes the asset optimization of PNM’s jurisdictional capacity as well as the capacity excluded from retail rates. FERC has jurisdiction over wholesale power and transmission rates. TNMP TNMP is an electric utility providing services in Texas under the TECA. TNMP’s operations are subject to traditional rate regulation by the PUCT. TNMP provides transmission and distribution services at regulated rates to various REPs that, in turn, provide retail electric service to consumers within TNMP’s service area. TNMP also provides transmission services at regulated rates to other utilities that interconnect with TNMP’s facilities. Corporate and Other The Corporate and Other segment includes PNMR holding company activities, primarily related to corporate level debt and PNMR Services Company. The activities of PNMR Development, NM Capital, and the equity method investment in NMRD are also included in Corporate and Other. Eliminations of intercompany income and expense transactions are reflected in the Corporate and Other segment. PNMR SEGMENT INFORMATION The following tables present summarized financial information for PNMR by segment. PNM and TNMP each operate in only one segment. Therefore, tabular segment information is not presented for PNM and TNMP. 2019 PNM TNMP Corporate and Other PNMR Consolidated (In thousands) Electric operating revenues $ 1,093,822 $ 363,781 $ — $ 1,457,603 Cost of energy 317,725 95,087 — 412,812 Utility margin 776,097 268,694 — 1,044,791 Other operating expenses 554,661 98,621 (20,499 ) 632,783 Depreciation and amortization 160,368 84,259 23,181 267,808 Operating income (loss) 61,068 85,814 (2,682 ) 144,200 Interest income 14,303 — (281 ) 14,022 Other income (deductions) 26,989 4,131 (1,477 ) 29,643 Interest charges (72,900 ) (29,100 ) (19,016 ) (121,016 ) Segment earnings (loss) before income taxes 29,460 60,845 (23,456 ) 66,849 Income taxes (benefit) (25,962 ) 5,046 (4,366 ) (25,282 ) Segment earnings (loss) 55,422 55,799 (19,090 ) 92,131 Valencia non-controlling interest (14,241 ) — — (14,241 ) Subsidiary preferred stock dividends (528 ) — — (528 ) Segment earnings (loss) attributable to PNMR $ 40,653 $ 55,799 $ (19,090 ) $ 77,362 At December 31, 2019: Total Assets $ 5,242,991 $ 1,860,439 $ 195,344 $ 7,298,774 Goodwill $ 51,632 $ 226,665 $ — $ 278,297 2018 PNM TNMP Corporate and Other PNMR Consolidated (In thousands) Electric operating revenues $ 1,091,965 $ 344,648 $ — $ 1,436,613 Cost of energy 314,036 85,690 — 399,726 Utility margin 777,929 258,958 — 1,036,887 Other operating expenses 481,030 96,272 (17,650 ) 559,652 Depreciation and amortization 151,866 66,189 23,133 241,188 Operating income 145,033 96,497 (5,483 ) 236,047 Interest income 13,089 — 2,451 15,540 Other income (deductions) (17,312 ) 4,065 (2,039 ) (15,286 ) Interest charges (76,458 ) (32,091 ) (18,695 ) (127,244 ) Segment earnings (loss) before income taxes 64,352 68,471 (23,766 ) 109,057 Income taxes (5,971 ) 16,880 (3,134 ) 7,775 Segment earnings (loss) 70,323 51,591 (20,632 ) 101,282 Valencia non-controlling interest (15,112 ) — — (15,112 ) Subsidiary preferred stock dividends (528 ) — — (528 ) Segment earnings (loss) attributable to PNMR $ 54,683 $ 51,591 $ (20,632 ) $ 85,642 At December 31, 2018: Total Assets $ 5,035,883 $ 1,665,177 $ 164,491 $ 6,865,551 Goodwill $ 51,632 $ 226,665 $ — $ 278,297 2017 PNM TNMP Corporate and Other PNMR Consolidated (In thousands) Electric operating revenues $ 1,104,230 $ 340,773 $ — $ 1,445,003 Cost of energy 321,677 85,802 — 407,479 Utility margin 782,553 254,971 — 1,037,524 Other operating expenses 414,457 98,221 (22,135 ) 490,543 Depreciation and amortization 147,017 63,146 21,779 231,942 Operating income (loss) 221,079 93,604 356 315,039 Interest income 8,454 — 7,462 15,916 Other income (deductions) 22,132 3,551 (3,254 ) 22,429 Interest charges (82,697 ) (30,084 ) (14,844 ) (127,625 ) Segment earnings (loss) before income taxes 168,968 67,071 (10,280 ) 225,759 Income taxes (benefit) 81,555 31,512 17,273 130,340 Segment earnings (loss) 87,413 35,559 (27,553 ) 95,419 Valencia non-controlling interest (15,017 ) — — (15,017 ) Subsidiary preferred stock dividends (528 ) — — (528 ) Segment earnings (loss) attributable to PNMR $ 71,868 $ 35,559 $ (27,553 ) $ 79,874 At December 31, 2017: Total Assets $ 4,921,563 $ 1,500,770 $ 223,770 $ 6,646,103 Goodwill $ 51,632 $ 226,665 $ — $ 278,297 The Company defines utility margin as electric operating revenues less cost of energy. Cost of energy consists primarily of fuel and purchase power costs for PNM and costs charged by third-party transmission providers for TNMP. The Company believes that utility margin provides a more meaningful basis for evaluating operations than electric operating revenues since substantially all such costs are offset in revenues as fuel and purchase power costs are passed through to customers under PNM’s FPPAC and third-party transmission costs are passed on to customers through TNMP’s transmission cost recovery factor. Utility margin is not a financial measure required to be presented under GAAP and is considered a non-GAAP measure. Major Customers No individual customer accounted for more than 10% of the electric operating revenues of PNMR or PNM. Three REPs accounted for more than 10% of the electric operating revenues of TNMP, as follows: Year Ended December 31, 2019 2018 2017 REP A 22 % 21 % 16 % REP B 17 % 15 % 11 % REP C 12 % 12 % 10 % |

Revenue from Contract with Customer [Abstract] | |
Electric Operating Revenue | Electric Operating Revenues PNMR is an investor-owned holding company with two regulated utilities providing electricity and electric services in New Mexico and Texas. PNMR’s electric utilities are PNM and TNMP. Revenue Recognition Electric operating revenues are recorded in the period of energy delivery, which includes estimated amounts for service rendered but unbilled at the end of each accounting period. The determination of the energy sales billed to individual customers is based on the reading of their meters, which occurs on a systematic basis throughout the month. At the end of each month, amounts of energy delivered to customers since the date of the last meter reading and the corresponding unbilled revenue are estimated. Unbilled electric revenue is estimated based on daily generation volumes, estimated customer usage by class, line losses, historical trends and experience, and applicable customer rates. Amounts billed are generally due within the next month. The Company does not incur incremental costs to obtain contracts for its energy services. PNM’s wholesale electricity sales are recorded as electric operating revenues and wholesale electricity purchases are recorded as costs of energy sold. In accordance with GAAP, derivative contracts that are subject to unplanned netting are recorded net in earnings. A “book-out” is the planned or unplanned netting of off-setting purchase and sale transactions. A book-out is a transmission mechanism to reduce congestion on the transmission system or administrative burden. For accounting purposes, a book-out is the recording of net revenues upon the settlement of a derivative contract. Unrealized gains and losses on derivative contracts that are not designated for hedge accounting are classified as economic hedges. Economic hedges are defined as derivative instruments, including long-term power and fuel supply agreements, used to hedge generation assets and purchased power costs. Changes in the fair value of economic hedges are reflected in results of operations, with changes related to economic hedges on sales included in operating revenues and changes related to economic hedges on purchases included in cost of energy sold. See Note 9. The Company adopted ASU 2014-09 – Revenue from Contracts with Customers (Topic 606) as of January 1, 2018, its required effective date, using the modified retrospective method of adoption. The adoption of ASU 2014-09 did not result in changes to the nature, amount, and timing of the Company’s existing revenue recognition processes or information technology infrastructure. Therefore, the adoption of ASU 2014-09 had no effect on the amount of revenue recorded in 2018 compared to the amount that would have been recorded under prior GAAP, no effect on total electric operating revenues or any other caption within the Company’s financial statements, and no cumulative effect adjustment was recorded. Revenues for 2019 and 2018 are presented in accordance with the standard on the Consolidated Statements of Earnings and 2017 revenues are presented on a comparative basis. Additional disclosures to further disaggregate 2019 and 2018 revenues are presented below. The Company adopted ASU 2018-18 – Collaborative Arrangements (Topic 808) in 2019, ahead of its required effective date, using the retrospective method of adoption. The Company has collaborative arrangements related to its interest in SJGS, Four Corners, PVNGS, and Luna. The Company has determined that during the years ended December 31, 2019, 2018, and 2017 none of the joint owners in its collaborative arrangements were customers under Topic 606. Therefore, the adoption of this standard did not impact the financial statements. The Company will continue to evaluate transactions between collaborative arrangement participants in future periods under the requirements of the new standard. PNM and TNMP recognize revenue as they satisfy performance obligations, which typically occurs as the customer or end-user consumes the electric service provided. Electric services are typically for a bundle of services that are distinct and transferred to the end-user in one performance obligation measured by KWh or KW. Electric operating revenues are recorded in the period of energy delivery, including estimated unbilled amounts. As permitted under GAAP, the Company has elected to exclude all sales and similar taxes from revenue. Revenue from contracts with customers is recorded based upon the total authorized tariff price at the time electric service is rendered, including amounts billed under arrangements qualifying as an Alternative Revenue Program (“ARP”). ARP arrangements are agreements between PNM or TNMP and its regulator that allow PNM or TNMP to adjust future rates in response to past activities or completed events, if certain criteria are met. GAAP requires that ARP revenues be reported separately from contracts with customers. ARP revenues in a given period include the recognition of “originating” ARP revenues (i.e. when the regulator-specific conditions are met) in the period, offset by the reversal of ARP revenues when billed to customers. Sources of Revenue Additional information about the nature of revenues is provided below. Additional information about matters affecting PNM’s and TNMP’s regulated revenues is provided in Note 17. Revenue from Contracts with Customers PNM NMPRC Regulated Retail Electric Service – PNM provides electric generation, transmission, and distribution service to its rate-regulated customers in New Mexico. PNM’s retail electric service territory covers a large area of north central New Mexico, including the cities of Albuquerque, Rio Rancho, and Santa Fe, and certain areas of southern New Mexico. Customer rates for retail electric service are set by the NMPRC and revenue is recognized as energy is delivered to the customer. PNM invoices customers on a monthly basis for electric service and generally collects billed amounts within one month. Transmission Service to Third Parties – PNM owns transmission lines that are interconnected with other utilities in New Mexico, Texas, Arizona, Colorado, and Utah. Transmission customers receive service for the transmission of energy owned by the customer utilizing PNM’s transmission facilities. Customers generally receive transmission services, which are regulated by FERC, from PNM through PNM’s Open Access Transmission Tariff (“OATT”) or a specific contract. Customers are billed based on capacity and energy components on a monthly basis. Miscellaneous – Beginning on January 1, 2018, PNM acquired a 65 MW interest in SJGS Unit 4, which is held as merchant plant as ordered by the NMPRC (Note 16). PNM sells power from 36 MW of this capacity to a third party at a fixed price that is recorded as revenue from contracts with customers. PNM is obligated to deliver power under this arrangement only when SJGS Unit 4 is operating. Other market sales from this 65 MW interest are recorded in other electric operating revenues. TNMP PUCT Regulated Retail Electric Service – TNMP provides transmission and distribution services in Texas under the provisions of TECA and the Texas Public Utility Regulatory Act. TNMP is subject to traditional cost-of-service regulation with respect to rates and service under the jurisdiction of the PUCT and certain municipalities. TNMP’s transmission and distribution activities are solely within ERCOT and not subject to traditional rate regulation by FERC. TNMP provides transmission and distribution services at regulated rates to various REPs that, in turn, provide retail electric service to consumers within TNMP’s service territory. Revenue is recognized as energy is delivered to the consumer. TNMP invoices REPs on a monthly basis and is generally paid within a month. Transmission Cost of Service (“TCOS”) – TNMP is a transmission service provider that is allowed to recover its TCOS through a network transmission rate that is approved by the PUCT. TCOS customers are other utilities that receive service for the transmission of energy owned by the customer utilizing TNMP’s transmission facilities. Alternative Revenue Programs The Company defers certain costs and records certain liabilities pursuant to the rate actions of the NMPRC, PUCT, and FERC. ARP revenues, which are discussed above, include recovery or refund provisions under PNM’s renewable energy rider and true-ups to PNM’s formula transmission rates; TNMP’s AMS surcharge, transmission cost recovery factor, and the impacts of the PUCT’s January 25, 2018 order regarding the change in the federal corporate income tax rate; and the energy efficiency incentive bonus at both PNM and TNMP. GAAP provides for the recognition of regulatory assets and liabilities for the difference between ARP revenues and amounts billed under those programs. Regulatory assets and liabilities are amortized into earnings as amounts are billed. As discussed in Note 17, TNMP’s 2018 Rate Case integrates AMS costs into base rates beginning January 1, 2019. These costs are being amortized into earnings as alternative revenues over a period of five years . Other Electric Operating Revenues Other electric operating revenues consist primarily of PNM’s sales for resale meeting the definition of a derivative under GAAP. Derivatives are not considered revenue from contracts with customers. PNM engages in activities meeting the definition of derivatives to optimize its existing jurisdictional assets and long-term power agreements through spot market, hour-ahead, day- ahead, week-ahead, month-ahead, and other sales of excess generation not required to fulfill retail load and contractual commitments. Through December 31, 2017, PNM’s 134 MW share of Unit 3 at PVNGS was excluded from retail rates and was being sold in the wholesale market. Effective January 1, 2018, PNM’s share of PVNGS Unit 3 is included in retail rates and recorded as revenue from contracts with customer. Disaggregation of Revenues A disaggregation of revenues from contracts with customers by the type of customer is presented in the table below. The table also reflects ARP revenues and other revenues. PNM TNMP PNMR Consolidated Year Ended December 31, 2019 (In thousands) Electric Operating Revenues: Contracts with customers: Retail electric revenue Residential $ 427,883 $ 150,742 $ 578,625 Commercial 396,987 116,953 513,940 Industrial 69,601 22,405 92,006 Public authority 20,322 5,694 26,016 Economy energy service 25,757 — 25,757 Transmission 57,214 66,948 124,162 Miscellaneous 13,134 3,568 16,702 Total revenues from contracts with customers 1,010,898 366,310 1,377,208 Alternative revenue programs 1,987 (2,529 ) (542 ) Other electric operating revenues 80,937 — 80,937 Total Electric Operating Revenues $ 1,093,822 $ 363,781 $ 1,457,603 Year Ended December 31, 2018 Electric Operating Revenues: Contracts with customers: Retail electric revenue Residential $ 433,009 $ 130,288 $ 563,297 Commercial 408,333 111,261 519,594 Industrial 61,119 17,317 78,436 Public authority 21,688 5,609 27,297 Economy energy service 26,764 — 26,764 Transmission 54,280 66,991 121,271 Miscellaneous 14,098 8,983 23,081 Total revenues from contracts with customers 1,019,291 340,449 1,359,740 Alternative revenue programs (2,443 ) 4,199 1,756 Other electric operating revenues 75,117 — 75,117 Total Electric Operating Revenues $ 1,091,965 $ 344,648 $ 1,436,613 Contract Balances Performance obligations related to contracts with customers are typically satisfied when the energy is delivered and the customer or end-user utilizes the energy. Accounts receivable from customers represent amounts billed, including amounts under ARP programs. For PNM, accounts receivable reflected on the Consolidated Balance Sheets, net of allowance for uncollectible accounts, includes $59.3 million and $61.7 million at December 31, 2019 and 2018 resulting from contracts with customers. All of TNMP’s accounts receivable results from contracts with customers. Contract assets are an entity’s right to consideration in exchange for goods or services that the entity has transferred to a customer when that right is conditioned on something other than the passage of time (for example, the entity’s future performance). The Company has no contract assets as of December 31, 2019 . Contract liabilities arise when consideration is received in advance from a customer before satisfying the performance obligations. Therefore, revenue is deferred and not recognized until the obligation is satisfied. Under its OATT, PNM accepts upfront consideration for capacity reservations requested by transmission customers, which requires PNM to defer the customer’s transmission capacity rights for a specific period of time. PNM recognizes the revenue of these capacity reservations over the period it defers the customer’s capacity rights. Other utilities pay PNM and TNMP in advance for the joint-use of their utility poles. These revenues are recognized over the period of time specified in the joint-use contract, typically for one calendar year. Deferred revenues on these arrangements are recorded as contract liabilities. PNMR’s, PNM’s, and TNMP’s contract liabilities and related revenues are insignificant for all periods presented. The Company has no other arrangements with remaining performance obligations to which a portion of the transaction price would be required to be allocated. |

Stockholders' Equity Note [Abstract] | |
Stockholders' Equity | Stockholders’ Equity Common Stock and Equity Contributions PNMR, PNM, and TNMP did not issue any common stock during the three -year period ended December 31, 2019 . PNMR did no t fund any cash equity contributions to PNM during the three-year period ended December 31, 2019 , and funded $80.0 million in 2019 , $30.0 million in 2018 and $50.0 million in 2017 to TNMP. PNMR offers shares of PNMR common stock through the PNMR Direct Plan. PNMR utilizes shares of its common stock purchased on the open market, by an independent agent, rather than issuing additional shares to satisfy subscriptions under the PNMR Direct Plan. The shares of PNMR common stock utilized in the PNMR Direct Plan are offered under a SEC shelf registration statement that expires in March 2021. See Note 7 regarding the planned issuance of common stock under the PNMR 2020 Forward Equity Sale Agreements. Dividends on Common Stock The declaration of common dividends by PNMR is dependent upon a number of factors, including the ability of PNMR’s subsidiaries to pay dividends. PNMR’s primary sources of dividends are its operating subsidiaries. PNM declared and paid cash dividends to PNMR of zero , $77.4 million , and $60.7 million in 2019 , 2018 , and 2017 . TNMP declared and paid cash dividends to PNMR of $55.3 million , $41.9 million , and $44.4 million in 2019 , 2018 , and 2017 . The NMPRC has placed certain restrictions on the ability of PNM to pay dividends to PNMR, including the restriction that PNM cannot pay dividends that cause its debt rating to fall below investment grade. The NMPRC provisions allow PNM to pay dividends, without prior NMPRC approval, from current earnings, which is determined on a rolling four quarter basis, or from equity contributions previously made by PNMR. The Federal Power Act also imposes certain restrictions on dividends by public utilities, including that dividends cannot be paid from paid-in capital. Prior to July 2018, the Company’s revolving credit facilities and term loans contained a covenant requiring the maintenance of debt-to-capitalization ratios of less than or equal to 65% . In July 2018, PNMR’s revolving credit facility and term loans were amended such that PNMR is now required to maintain a debt-to-capitalization ratio of less than or equal to 70% . The debt-to-capitalization ratio requirements remain at less than or equal to 65% for PNM and TNMP. These debt-to-capitalization ratio requirements could limit the amounts of dividends that could be paid. PNM also has other financial covenants that limit the transfer of assets, through dividends or other means, including a requirement to obtain the approval of certain financial counterparties to transfer more than five percent of PNM’s assets. As of December 31, 2019 , none of the numerical tests would restrict the payment of dividends from the retained earnings of TNMP, restrictions related to retained earnings under the Federal Power Act may limit the payment of dividends by PNM to $283.5 million , and the 70% debt-to-capitalization covenant would allow the payment of dividends by PNMR of up to $257.6 million . In addition, the ability of PNMR to declare dividends is dependent upon the extent to which cash flows will support dividends, the availability of retained earnings, financial circumstances and performance, current and future regulatory decisions, Congressional and legislative acts, and economic conditions. Conditions imposed by the NMPRC or PUCT, future growth plans and related capital requirements, and business considerations may also affect PNMR’s ability to pay dividends. Preferred Stock PNM’s cumulative preferred shares outstanding bear dividends at 4.58% per annum. PNM preferred stock does not have a mandatory redemption requirement, but may be redeemed, at PNM’s option, at 102% of the stated value plus accrued dividends. The holders of the PNM preferred stock are entitled to payment before the holders of common stock in the event of any liquidation or dissolution or distribution of assets of PNM. In addition, PNM’s preferred stock is not entitled to a sinking fund and cannot be converted into any other class of stock of PNM. PNMR and TNMP have no preferred stock outstanding. The authorized shares of PNMR and TNMP preferred stock are 10 million shares and 1 million shares. |

Debt Disclosure [Abstract] | |
Financing | Financing The Company’s financing strategy includes both short-term and long-term borrowings. The Company utilizes short-term revolving credit facilities, as well as cash flows from operations, to provide funds for both construction and operating expenditures. Depending on market and other conditions, the Company will periodically sell long-term debt or enter into term loan arrangements and use the proceeds to reduce borrowings under the revolving credit facilities or refinance other debt. Prior to July 2018, each of the Company’s revolving credit facilities and term loans contained a single financial covenant, which required the maintenance of a debt-to-capitalization ratio of less than or equal to 65% . In July 2018, the PNMR and the PNMR Development agreements were each amended such that each is now required to maintain a debt-to-capitalization ratio of less than or equal to 70% . The debt-to-capitalization ratio requirement remains at less than or equal to 65% for the PNM and TNMP agreements. The Company’s revolving credit facilities and term loans generally also contain customary covenants, events of default, cross-default provisions, and change-of-control provisions. PNM must obtain NMPRC approval for any financing transaction having a maturity of more than 18 months. In addition, PNM files its annual short-term financing plan with the NMPRC. Financing Activities PNMR At January 1, 2017, PNMR had outstanding the $150.0 million PNMR 2015 Term Loan, which matured and was repaid on March 9, 2018. As discussed in Note 16, at January 1, 2018, NM Capital, a wholly-owned subsidiary of PNMR, had outstanding $50.1 million of the $125.0 million term loan agreement (the “BTMU Term Loan”) with BTMU. PNMR, as parent company of NM Capital, guaranteed NM Capital’s obligations to BTMU. NM Capital utilized the proceeds of the BTMU Term Loan to provide funding of $125.0 million (the “Westmoreland Loan”) to a ring-fenced, bankruptcy-remote, special-purpose entity subsidiary of Westmoreland to finance Westmoreland’s purchase of SJCC. The BTMU Term Loan agreement required that NM Capital utilize all amounts, less taxes and fees, it received under the Westmoreland Loan to repay the BTMU Term Loan. On May 22, 2018, the full principal balance outstanding under the Westmoreland Loan of $50.1 million was repaid. NM Capital used a portion of the proceeds to repay all remaining principal of $43.0 million owed under the BTMU Term Loan. These payments effectively terminated the loan agreements. In addition, PNMR’s guarantee of NM Capital’s obligations was also effectively terminated. See Note 10. At January 1, 2017, PNMR had outstanding letters of credit arrangements with JPMorgan Chase Bank, N.A. (the “JPM LOC Facility”) under which letters of credit aggregating $30.3 million were issued to facilitate the posting of reclamation bonds, which SJCC was required to post in connection with permits relating to the operation of the San Juan mine. On March 15, 2019, WSJ LLC acquired the assets of SJCC following the bankruptcy of Westmoreland. WSJ LLC assumed the obligations to PNMR under the letters of credit support. See Note 16. On January 1, 2017, PNMR had outstanding two term loan agreements: (1) a $100.0 million term loan agreement (the “PNMR 2016 One-Year Term Loan”) and (2) a $100.0 million term loan agreement (the “PNMR 2016 Two-Year Term Loan”) that matured on December 21, 2018. On December 15, 2017, the PNMR 2016 One -Year Term Loan was extended to December 14, 2018. In December 2018, both the PNMR 2016 One -Year Term Loan (as extended) and the PNMR 2016 Two -Year Term Loan were repaid. On March 9, 2018, PNMR issued $300.0 million aggregate principal amount of 3.25% SUNs (the “PNMR 2018 SUNs”), which mature on March 9, 2021. The proceeds from the offering were used to repay the $150.0 million PNMR 2015 Term Loan that was due on March 9, 2018 and to reduce borrowings under the PNMR Revolving Credit Facility. On November 26, 2018, PNMR Development entered into a $90.0 million term loan agreement (the “PNMR Development Term Loan”), among PNMR Development and KeyBank, N.A., as administrative agent and sole lender. Proceeds from the PNMR Development Term Loan were used to repay short-term borrowings under the PNMR Development’s revolving credit facility and to repay borrowings under its intercompany loan from PNMR. The PNMR Development Term Loan bears interest at a variable rate, which was 2.60% on December 31, 2019, and matures on November 26, 2020. PNMR, as parent company of PNMR Development, has guaranteed PNMR Development’s obligations under the loan. The PNMR Development Term Loan requires PNMR to maintain a debt-to-capitalization ratio of less than or equal to 70% , and contains customary events of default, a cross-default provision, and a change-of-control provision. On December 14, 2018, PNMR entered into a $150.0 million term loan agreement (the “PNMR 2018 One -Year Term Loan”) among PNMR, the lenders identified therein, and MUFG Bank, Ltd., as administrative agent. The proceeds from the PNMR 2018 One -Year Term Loan were used to repay the PNMR 2016 One -Year Term Loan (as extended), a portion of the PNMR 2016 Two -Year Term Loan, and for general corporate purposes. On December 13, 2019, the PNMR 2018 One -Year Term Loan was extended to June 11, 2021 (as extended, the “PNMR 2019 Term Loan”). The PNMR 2019 Term Loan bears interest at a variable rate, which was 2.70% at December 31, 2019. On December 21, 2018, PNMR entered into a $50.0 million term loan agreement (the “PNMR 2018 Two -Year Term Loan”), between PNMR and Bank of America, N.A. as sole lender. Proceeds from the PNMR 2018 Two -Year Term Loan were used to repay the remaining amount owed under the PNMR 2016 Two -Year Term Loan and for general corporate purposes. The PNMR 2018 Two -Year Term Loan bears interest at a variable rate, which was 2.60% at December 31, 2019, and matures on December 21, 2020. On January 7, 2020, PNMR entered into forward sale agreements with each of Citibank N.A., and Bank of America N.A., as forward purchases and an underwriting agreement with Citigroup Global Markets Inc., and BofA Securities, Inc. as representatives of the underwriters named therein, relating to an aggregate of approximately 6.2 million shares of PNMR common stock (including 0.8 million shares of PNMR common stock pursuant to the underwriters’ option to purchase additional shares) with each of Citibank N.A., and Bank of America N.A., as forward purchasers (the “PNMR 2020 Forward Equity Sales Agreements”). On January 8, 2020, the underwriters exercised in full their option to purchase an additional 0.8 million shares of PNMR common stock and PNMR entered into separate forward sales agreements with respect to the additional shares. The initial forward sale price of $47.21 per share is subject to adjustments based on a net interest rate factor and by expected future dividends paid on PNMR common stock as specified in the forward sale agreements. PNMR did not initially receive any proceeds upon the execution of these agreements and, except in certain specified circumstances, has the option to elect physical, cash, or net share settlement on or before the date that is 12 months from their effective dates. PNMR expects to physically settle all shares under the agreements on or before January 7, 2021 at the then applicable forward sales price. Pursuant to a cash settlement of the PNMR 2020 Forward Equity Sales Agreements, PNMR would expect to receive significantly lower net proceeds or may owe cash, which could be a significant amount, to the forward purchasers. Under a net share settlement, PNMR would not receive any cash proceeds and may be required to deliver shares of PNMR common stock to the forward purchasers. The forward sale agreements meet the derivative scope exception requirements for contracts involving an entity’s own equity. Until settlement of the forward sale agreements, PNMR’s EPS dilution resulting from the agreements, if any, will be determined using the treasury stock method, which will result in dilution during periods when the average market price of PNMR stock during the reporting period is higher than the applicable forward sales price as of the end of that period. PNMR has an automatic shelf registration that provides for the issuance of various types of debt and equity securities that expires in March 2021. PNM At January 1, 2017, PNM had outstanding a $175.0 million term loan agreement (the “PNM 2016 Term Loan”) that matured on November 17, 2017. The PNM 2016 Term Loan was repaid on July 20, 2017. At January 1, 2017, PNM had $37.0 million of outstanding PCRBs, which have a final maturity of June 1, 2040, and $20.0 million of outstanding PCRBs which have a final maturity of June 1, 2042. These PCRBs were subject to mandatory tender for remarketing on June 1, 2017 and were successfully remarketed on that date. The $37.0 million of PCRBs now bear interest at 2.125% and the $20.0 million of PCRBs now bear interest at 2.45% . Both series are now subject to mandatory tender for remarketing on June 1, 2022. On July 20, 2017, PNM entered into a $200.0 million term loan agreement (the “PNM 2017 Term Loan”) between PNM and JPMorgan Chase Bank, N.A., as lender and administrative agent, and U.S. Bank National Association, as lender. PNM used the proceeds of the PNM 2017 Term Loan to prepay without penalty the $175.0 million PNM 2016 Term Loan and to reduce short-term borrowings. The PNM 2017 Term Loan was repaid on January 18, 2019. On July 28, 2017, PNM entered into an agreement (the “PNM 2017 Senior Unsecured Note Agreement”) with institutional investors for the sale of $450.0 million aggregate principal amount of eight series of Senior Unsecured Notes (the “PNM 2018 SUNs”) offered in private placement transactions. On May 14, 2018, PNM issued $350.0 million of the PNM 2018 SUNs under that agreement (at fixed annual interest rates ranging from 3.15% to 4.50% for terms between 5 and 30 years ) and used the proceeds to repay an equal amount of PNM’s 7.95% SUNs that matured on May 15, 2018. On July 31, 2018, PNM issued the remaining $100.0 million of the PNM 2018 SUNs (at fixed annual interest rates of 3.78% and 4.60% for terms of 10 and 30 years ) and used the proceeds to repay an equal amount of PNM’s 7.50% SUNs on August 1, 2018. The PNM 2017 Senior Unsecured Note Agreement includes customary covenants, including a covenant that requires the maintenance of a debt-to-capitalization ratio of less than or equal to 65% , customary events of default, including a cross-default provision, and covenants regarding parity of financial covenants, liens and guarantees with respect to PNM’s material credit facilities. In the event of a change of control, PNM will be required to offer to prepay the PNM 2018 SUNs at par. PNM will have the right to redeem any or all of the PNM 2018 SUNs prior to their respective maturities, subject to payment of a customary make-whole premium. On April 9, 2018, PNMR Development deposited $68.2 million with PNM related to potential transmission network interconnections. PNM used the deposit to repay intercompany borrowings. PNM was required to pay interest to PNMR Development to the extent work under the interconnections has not been performed. The entire deposit of $68.2 million and accrued interest of $5.7 million was refunded in November 2019. The interconnection deposit and related refund is presented in financing activities and the interest payment is presented in operating activities on PNM’s Consolidated Statements of Cash Flows for the years ended December 31, 2019 and 2018. During the years ended December 31, 2019 and December 31, 2018, PNM recognized $3.3 million and $2.4 million of interest expense under the agreement. At December 31, 2018, PNM’s obligation under the interconnection agreement with PNMR Development of $68.2 million , excluding unpaid interest, is reflected in other deferred credits on PNM’s Consolidated Balance Sheets. As required by GAAP, all intercompany transactions related to this deposit have been eliminated on PNMR’s Consolidated Financial Statements. On January 18, 2019, PNM entered into a $250.0 million term loan agreement (the “PNM 2019 $250.0 million Term Loan”) among PNM, the lenders identified therein, and U.S. Bank N.A., as administrative agent. PNM used the proceeds of the PNM 2019 $250.0 million Term Loan to repay the PNM 2017 Term Loan, to reduce short-term borrowings under the PNM Revolving Credit Facility, and for general corporate purposes. The PNM 2019 $250.0 million Term Loan bears interest at a variable rate, which was 2.45% at December 31, 2019, and must be repaid on or before July 17, 2020. On December 18, 2019, PNM entered into a $40.0 million term loan agreement (the “PNM 2019 $40.0 million Term Loan”), between PNM and Bank of America, N.A. as sole lender and administrative agent. PNM used the proceeds of the PNM 2019 $40.0 million Term Loan to reduce short-term borrowings under the PNM Revolving Credit Facility and for general corporate purposes. The PNM 2019 $40.0 million Term Loan bears interest at a variable rate, which was 2.39% at December 31, 2019, and must be repaid on or before June 18, 2021. See discussion of PNM’s SJGS Abandonment Application in Note 17, which includes a request to issue approximately $361 million of energy transition bonds, as provided by the ETA, upon the proposed retirement of SJGS in 2022. PNM has a shelf registration statement, which will expire in May 2020, with capacity for the issuance of up to $475.0 million of senior unsecured notes. TNMP On June 14, 2017, TNMP entered into an agreement which provided TNMP would issue $60.0 million aggregate principal amount of 3.22% first mortgage bonds, due 2027, subject to satisfaction of certain conditions. TNMP issued the bonds on August 24, 2017 and used the proceeds to reduce short-term and intercompany debt and for general corporate purposes. On June 28, 2018, TNMP entered into an agreement under which TNMP issued $60.0 million aggregate principal amount of 3.85% first mortgage bonds, due 2028. On July 25, 2018, TNMP entered into a $20.0 million term loan agreement. On December 17, 2018, the TNMP 2018 Term Loan agreement was amended to provide additional funding of $15.0 million , which results in a total committed amount of $35.0 million under the agreement (the “TNMP 2018 Term Loan”). TNMP used the proceeds from these issuances to repay short-term borrowings and for TNMP’s general corporate purposes. The TNMP 2018 Term Loan was repaid on December 30, 2019. On February 26, 2019, TNMP entered into the TNMP 2019 Bond Purchase Agreement with institutional investors for the sale of $305.0 million aggregate principal amount of four series of TNMP first mortgage bonds (the “TNMP 2019 Bonds”) offered in private placement transactions. TNMP issued $225.0 million of TNMP 2019 Bonds on March 29, 2019 and used the proceeds to repay TNMP’s $172.3 million 9.50% first mortgage bonds at their maturity on April 1, 2019, as well as to repay borrowing under the TNMP Revolving credit Facility and for general corporate purposes. TNMP issued the remaining $80.0 million of TNMP 2019 Bonds on July 1, 2019 and used the proceeds to repay borrowing under the TNMP Revolving Credit Facility and for general corporate purposes. The terms of the TNMP 2019 Bond Purchase Agreement include customary covenants, including a covenant that requires TNMP to maintain a debt-to-capitalization ratio of less than or equal to 65% , customary events of default, a cross-default provision, and a change-of-control provision. TNMP has the right to redeem any or all of the TNMP 2019 Bonds prior to their respective maturities, subject to payment of a customary make-whole premium. Interest Rate Hedging Activities At January 1, 2017, PNMR had a hedging agreement that effectively established a fixed interest rate of 1.927% for borrowings under the PNMR 2015 Term Loan through its maturity on March 9, 2018. In 2017, PNMR entered into three separate four -year hedging agreements that effectively established fixed interest rates of 1.926% , 1.823% , and 1.629% , plus customary spreads over LIBOR, subject to change if there is a change in PNMR’s credit rating, for three separate tranches, each of $50.0 million , of its variable rate debt. These hedge agreements are accounted for as cash flow hedges and had fair values of $0.4 million and $1.0 million that are included in other current liabilities and other current assets on the Consolidated Balance Sheets at December 31, 2019 and 2018. As discussed in Note 3, changes in the fair value of the cash flow hedges are deferred in AOCI and amounts reclassified to the Condensed Consolidated Statement of Earnings are recorded in interest charges. The fair values were determined using Level 2 inputs under GAAP, including using forward LIBOR curves under the mid-market convention to discount cash flows over the remaining term of the agreement. On January 1, 2019, the Company adopted Accounting Standards Update 2017-12- Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. Adoption of the updated standard did not have a significant impact on these cash flow hedges. Borrowing Arrangements Between PNMR and its Subsidiaries PNMR has one-year intercompany loan agreements with its subsidiaries. Individual subsidiary loan agreements vary in amount up to $100.0 million and have either reciprocal or non-reciprocal terms. Interest charged to the subsidiaries is equivalent to interest paid by PNMR on its short-term borrowings or the money-market interest rate if PNMR does not have any short-term borrowings outstanding. TNMP had no borrowings from PNMR at December 31, 2019 and no borrowings at February 21, 2020. TNMP had outstanding borrowings of $0.1 million from PNMR at December 31, 2018. PNM had no borrowings from PNMR at December 31, 2019 and no borrowings at February 21, 2020 . PNM had outstanding borrowings of $19.8 million from PNMR at December 31, 2018 . Short-term Debt Currently, the PNMR Revolving Credit Facility has a financing capacity of $300.0 million and the PNM Revolving Credit Facility has a financing capacity of $400.0 million . Both facilities currently expire on October 31, 2023 and contain options to be extended through October 2024, subject to approval by a majority of the lenders. The TNMP Revolving Credit Facility is a $75.0 million revolving credit facility secured by $75.0 million aggregate principal amount of TNMP first mortgage bonds. In September 2017, the TNMP Revolving Credit Facility was extended to mature on September 23, 2022. At January 1, 2017, PNM had a $50.0 million unsecured revolving credit facility (the “PNM 2014 New Mexico Credit Facility”) that was scheduled to expire on January 8, 2018. On December 12, 2017, PNM entered into a new $40.0 million unsecured revolving credit facility (the “PNM 2017 New Mexico Credit Facility”) by and among PNM, the lenders identified therein, U.S. Bank National Association, as Administrative Agent, and BOKF, NA dba Bank of Albuquerque, as Syndication Agent to replace the PNM 2014 New Mexico Credit Facility. The eight participating lenders are all banks that have a significant presence or are headquartered in New Mexico. The PNM 2017 New Mexico Credit Facility expires on December 12, 2022 and contains covenants and conditions similar to those in the PNM Revolving Credit Facility. On February 26, 2018, PNMR Development entered into a revolving credit facility with Wells Fargo Bank, National Association, as lender, which allowed PNMR Development to borrow up to $24.5 million on a revolving credit basis and also provides for the issuance of letters of credit. On February 22, 2019, PNMR Development amended its $24.5 million revolving credit facility to increase the capacity to $25.0 million . On July 22, 2019, the PNMR Development Revolving Credit Facility was amended to increase the capacity to $40.0 million with the option to further increase the capacity to $50 million upon 15-days advance notice. On February 21, 2020, PNMR Development extended the revolving credit facility to expire on February 23, 2021. The PNMR Development Revolving Credit Facility bears interest at a variable rate and contains terms similar to the PNMR Revolving Credit Facility. PNMR has guaranteed the obligations of PNMR Development under the facility. PNMR Development uses the facility to finance its participation in NMRD and for other activities.

Leases [Abstract] | |
Lease Commitments | Lease Commitments The Company enters into various lease agreements to meet its business needs and to satisfy the needs of its customers. Historically, the Company’s leases were classified as operating leases and included leases for generating capacity from PVNGS Units 1 and 2, certain rights-of-way agreements for transmission lines and facilities, vehicles and equipment necessary to construct and maintain the Company’s assets, and building and office equipment. In February 2016, the FASB issued ASU 2016-02 – Leases (Topic 842) to provide guidance on the recognition, measurement, presentation, and disclosure of leases. Among other things, ASU 2016-02 requires that all leases be recorded on the balance sheets by recognizing a present value liability for future cash flows of the lease agreement and a corresponding right-of-use asset. The Company adopted Topic 842 on January 1, 2019, its required effective date. The Company elected to use many of the practical expedients available upon adoption of the standard. As a result, the Company will continue to classify its leases existing as of December 31, 2018 as operating leases until they expire or are modified. In addition, the Company elected the practical expedient to not reevaluate the accounting for land easements and rights-of-way agreements existing at December 31, 2018. The Company also elected the use of the practical expedient to apply the requirements of the new standard on its effective date and has not restated prior periods to conform to the new guidance. Adoption of the lease standard has a material impact on the Company’s Consolidated Balance Sheets but does not have a material impact on the Consolidated Statements of Earnings or the Consolidated Statements of Cash Flows. Effective January 1, 2019, the Company accounts for contracts that convey the use and control of identified assets for a period of time as leases. The Company classifies leases as operating or financing by evaluating the terms of the lease agreement. Agreements under which the Company is likely to utilize substantially all of the economic value or life of the asset or that the Company is likely to own at the end of the lease term, either through purchase or transfer of ownership, are classified as financing leases. Leases not meeting these criteria are accounted for as operating leases. Agreements under which the Company is a lessor are insignificant. Leases with terms that are expected to exceed one year are recognized on the Company’s Consolidated Balance Sheets by recording a lease liability and corresponding right-of-use asset. PNMR, PNM, and TNMP determine present value for their leases using their incremental borrowing rates at the commencement date of the lease or, when readily available, the rate implicit in the agreement. In most cases the implicit interest rate is not available in the Company’s lease agreements. Operating lease expense is recognized within operating expenses according to the use of the asset on a straight-line basis. Financing lease costs are recognized by amortizing the right-of-use asset on a straight-line basis and by recording interest expense on the lease liability. Financing lease right-of-use assets amortization is reflected in depreciation and amortization and interest on financing lease liabilities is reflected as interest charges on the Company’s Consolidated Statements of Earnings. PVNGS PNM leases interests in Units 1 and 2 of PVNGS. The PVNGS leases were entered into in 1985 and 1986 and initially were scheduled to expire on January 15, 2015 for the four Unit 1 leases and January 15, 2016 for the four Unit 2 leases. Following procedures set forth in the PVNGS leases, PNM notified four of the lessors under the Unit 1 leases and one lessor under the Unit 2 lease that it would elect to renew those leases on the expiration date of the original leases. The four Unit 1 leases now expire on January 15, 2023 and the one Unit 2 lease now expires on January 15, 2024. The annual lease payments during the renewal periods aggregate $16.5 million for PVNGS Unit 1 and $1.6 million for Unit 2. The terms of each of the extended leases do not provide for additional renewal options beyond their currently scheduled expiration dates. PNM has the option to purchase the assets underlying each of the extended leases at their fair market value or to return the lease interests to the lessors on the expiration dates. Under the terms of the extended leases, PNM had until January 15, 2020 for the Unit 1 leases and has until January 15, 2021 for the Unit 2 lease to provide notices to the lessors of PNM’s intent to exercise the purchase options or to return the leased assets to the lessors. On January 3, 2020, PNM executed 60-day waivers of the deadline to provide notice of its intent to purchase or return the assets underlying the PVNGS Unit 1 leases. Under the waivers, PNM is required to provide notice by March 16, 2020. The waivers did not impact the PVNGS Unit 1 leases’ current January 15, 2023 expiration dates. PNM’s elections are independent for each lease and are irrevocable. In the proceeding addressing PNM’s 2017 IRP (Note 17), PNM agreed to promptly notify the NMPRC of a decision to extend the Unit 1 or 2 leases, or to exercise its option to purchase the leased assets at fair market value upon the expiration of leases. If PNM elects to exercise its purchase option under any of the leases, the leases provide an appraisal process to determine fair market value. If PNM elects to return the assets underlying the extended leases, PNM will retain certain obligations related to PVNGS, including costs to decommission the facility. PNM is depreciating its capital improvements related to the extended leases using NMPRC approved rates through the end of the NRC license period for each unit, which expire in June 2045 for Unit 1 and in June 2046 for Unit 2. Whether PNM retains or returns the assets underlying the extended leases, PNM will seek to recover its undepreciated investments, and any amounts paid to purchase the assets, as well as any other obligations related to PVNGS from NM retail customers. Any transfer of the assets underlying the leases will be required to comply with NRC licensing requirements. See Note 17 for information concerning the NMPRC’s treatment of PNM’s purchase of assets underlying 64.1 MW and extension of 114.6 MW of leased capacity in PVNGS Unit 2, the NM Supreme Court’s decision regarding PNM’s appeal of certain matters in the NM 2015 Rate Case, as well as information concerning a joint petition to investigate PNM’s option to purchase additional assets underlying the extended leased capacity in PVNGS. Covenants in PNM’s PVNGS Units 1 and 2 lease agreements limit PNM’s ability, without consent of the owner participants in the lease transactions, (i) to enter into any merger or consolidation, or (ii) except in connection with normal dividend policy, to convey, transfer, lease or dividend more than 5% of its assets in any single transaction or series of related transactions. PNM is exposed to losses under the PVNGS lease arrangements upon the occurrence of certain events that PNM does not consider to be reasonably likely to occur. Under certain circumstances (for example, the NRC issuing specified violation orders with respect to PVNGS or the occurrence of specified nuclear events), PNM would be required to make specified payments to the lessors and take title to the leased interests. If such an event had occurred as of December 31, 2019 , amounts due to the lessors under the circumstances described above would be up to $157.6 million , payable on January 15, 2020 in addition to the scheduled lease payments due on January 15, 2020. In such event, PNM would record the acquired assets at the lower of their fair value or the amount paid. Furthermore, the NRC places restrictions on the ownership of nuclear generating facilities. These restrictions could limit the transfer of ownership should PNM decide to return the assets underlying all or a portion of its current leased interests in PVNGS. In the event PNM decides to return these interests to the lessors, and a qualified buyer cannot be identified, PNM may be required to retain all of a portion of its existing leased capacity in PVNGS or be exposed to other claims for damages by the lessors. Land Easements and Rights-of-Ways Many of PNM’s electric transmission and distribution facilities are located on lands that require the grant of rights-of-way from governmental entities, Native American tribes, or private parties. PNM has completed several renewals of rights-of-way, the largest of which is a renewal with the Navajo Nation. PNM is obligated to pay the Navajo Nation annual payments of $6.0 million , subject to adjustment each year based on the Consumer Price Index, through 2029. PNM’s April 2018 payment for the amount due under the Navajo Nation right-of-way lease was $6.9 million , which included amounts due under the Consumer Price Index adjustment, and was used to determine PNM’s operating lease liability as of January 1, 2019. Changes in the Consumer Price Index subsequent to January 1, 2019 are considered variable lease payments. PNM has other prepaid rights-of-way agreements that are not accounted for as leases or recognized as a component of plant in service. PNM reflects the unamortized balance of these prepayments in other deferred charges on the Consolidated Balance Sheets and recognizes amortization expense associated with these agreements in the Consolidated Statement of Earnings over their term. As of December 31, 2019 and 2018, the unamortized balance of these rights-of-ways was $60.2 million and $63.0 million . During the years ended December 31, 2019 , 2018, and 2017, PNM recognized amortization expense associated with these agreements of $3.7 million , $3.8 million , and $3.5 million . Fleet Vehicles and Equipment As of December 31, 2018, all of the Company’s leases of fleet vehicles and equipment were classified as operating leases. Historically, the Company has utilized substantially all of the economic value of its fleet and equipment leases by the end of the lease term. The Company generally has the contractual ability to return its fleet vehicle and equipment leases to the lessor after one year provided the lessor can recover remaining amounts owed under the agreement from third-parties or through make-whole provisions in the contract but does not typically exercise this right. As a result, fleet vehicle and equipment leases commencing on or after January 1, 2019 are classified as financing leases. The Company’s fleet vehicle and equipment lease agreements include non-lease components for insignificant administrative and other costs that are billed over the life of the agreement. The Company has elected to combine these fees with the lease components of the agreement. Certain of the Company’s fleet vehicle and equipment leases contain residual value guarantees. At December 31, 2019 , residual value guarantees on fleet vehicle and equipment leases are $0.7 million , $1.2 million , and $1.9 million for PNM, TNMP, and PNMR. Other The Company holds a number of office space and office equipment leases. The Company’s current office space leases, all of which existed as of December 31, 2018, are classified as operating leases. These agreements include non-lease components for costs such as common area maintenance fees, which the Company has elected to combine with the lease component of the agreements. Certain of the Company’s office space leases are held between the Company’s consolidated subsidiaries and have been eliminated on consolidation. See Note 20. The Company’s office equipment leases are primarily for copiers and other graphics equipment. The Company classifies its office equipment leases existing as of December 31, 2018 as operating leases. Office equipment leases commencing on or after January 1, 2019 are classified as financing leases.

Effective January 1, 2019, the Company accounts for contracts that convey the use and control of identified assets for a period of time as leases. The Company classifies leases as operating or financing by evaluating the terms of the lease agreement. Agreements under which the Company is likely to utilize substantially all of the economic value or life of the asset or that the Company is likely to own at the end of the lease term, either through purchase or transfer of ownership, are classified as financing leases. Leases not meeting these criteria are accounted for as operating leases. Agreements under which the Company is a lessor are insignificant. Leases with terms that are expected to exceed one year are recognized on the Company’s Consolidated Balance Sheets by recording a lease liability and corresponding right-of-use asset. PNMR, PNM, and TNMP determine present value for their leases using their incremental borrowing rates at the commencement date of the lease or, when readily available, the rate implicit in the agreement. In most cases the implicit interest rate is not available in the Company’s lease agreements. Operating lease expense is recognized within operating expenses according to the use of the asset on a straight-line basis. Financing lease costs are recognized by amortizing the right-of-use asset on a straight-line basis and by recording interest expense on the lease liability. Financing lease right-of-use assets amortization is reflected in depreciation and amortization and interest on financing lease liabilities is reflected as interest charges on the Company’s Consolidated Statements of Earnings. PVNGS PNM leases interests in Units 1 and 2 of PVNGS. The PVNGS leases were entered into in 1985 and 1986 and initially were scheduled to expire on January 15, 2015 for the four Unit 1 leases and January 15, 2016 for the four Unit 2 leases. Following procedures set forth in the PVNGS leases, PNM notified four of the lessors under the Unit 1 leases and one lessor under the Unit 2 lease that it would elect to renew those leases on the expiration date of the original leases. The four Unit 1 leases now expire on January 15, 2023 and the one Unit 2 lease now expires on January 15, 2024. The annual lease payments during the renewal periods aggregate $16.5 million for PVNGS Unit 1 and $1.6 million for Unit 2. The terms of each of the extended leases do not provide for additional renewal options beyond their currently scheduled expiration dates. PNM has the option to purchase the assets underlying each of the extended leases at their fair market value or to return the lease interests to the lessors on the expiration dates. Under the terms of the extended leases, PNM had until January 15, 2020 for the Unit 1 leases and has until January 15, 2021 for the Unit 2 lease to provide notices to the lessors of PNM’s intent to exercise the purchase options or to return the leased assets to the lessors. On January 3, 2020, PNM executed 60-day waivers of the deadline to provide notice of its intent to purchase or return the assets underlying the PVNGS Unit 1 leases. Under the waivers, PNM is required to provide notice by March 16, 2020. The waivers did not impact the PVNGS Unit 1 leases’ current January 15, 2023 expiration dates. PNM’s elections are independent for each lease and are irrevocable. In the proceeding addressing PNM’s 2017 IRP (Note 17), PNM agreed to promptly notify the NMPRC of a decision to extend the Unit 1 or 2 leases, or to exercise its option to purchase the leased assets at fair market value upon the expiration of leases. If PNM elects to exercise its purchase option under any of the leases, the leases provide an appraisal process to determine fair market value. If PNM elects to return the assets underlying the extended leases, PNM will retain certain obligations related to PVNGS, including costs to decommission the facility. PNM is depreciating its capital improvements related to the extended leases using NMPRC approved rates through the end of the NRC license period for each unit, which expire in June 2045 for Unit 1 and in June 2046 for Unit 2. Whether PNM retains or returns the assets underlying the extended leases, PNM will seek to recover its undepreciated investments, and any amounts paid to purchase the assets, as well as any other obligations related to PVNGS from NM retail customers. Any transfer of the assets underlying the leases will be required to comply with NRC licensing requirements. See Note 17 for information concerning the NMPRC’s treatment of PNM’s purchase of assets underlying 64.1 MW and extension of 114.6 MW of leased capacity in PVNGS Unit 2, the NM Supreme Court’s decision regarding PNM’s appeal of certain matters in the NM 2015 Rate Case, as well as information concerning a joint petition to investigate PNM’s option to purchase additional assets underlying the extended leased capacity in PVNGS. Covenants in PNM’s PVNGS Units 1 and 2 lease agreements limit PNM’s ability, without consent of the owner participants in the lease transactions, (i) to enter into any merger or consolidation, or (ii) except in connection with normal dividend policy, to convey, transfer, lease or dividend more than 5% of its assets in any single transaction or series of related transactions. PNM is exposed to losses under the PVNGS lease arrangements upon the occurrence of certain events that PNM does not consider to be reasonably likely to occur. Under certain circumstances (for example, the NRC issuing specified violation orders with respect to PVNGS or the occurrence of specified nuclear events), PNM would be required to make specified payments to the lessors and take title to the leased interests. If such an event had occurred as of December 31, 2019 , amounts due to the lessors under the circumstances described above would be up to $157.6 million , payable on January 15, 2020 in addition to the scheduled lease payments due on January 15, 2020. In such event, PNM would record the acquired assets at the lower of their fair value or the amount paid. Furthermore, the NRC places restrictions on the ownership of nuclear generating facilities. These restrictions could limit the transfer of ownership should PNM decide to return the assets underlying all or a portion of its current leased interests in PVNGS. In the event PNM decides to return these interests to the lessors, and a qualified buyer cannot be identified, PNM may be required to retain all of a portion of its existing leased capacity in PVNGS or be exposed to other claims for damages by the lessors. Land Easements and Rights-of-Ways Many of PNM’s electric transmission and distribution facilities are located on lands that require the grant of rights-of-way from governmental entities, Native American tribes, or private parties. PNM has completed several renewals of rights-of-way, the largest of which is a renewal with the Navajo Nation. PNM is obligated to pay the Navajo Nation annual payments of $6.0 million , subject to adjustment each year based on the Consumer Price Index, through 2029. PNM’s April 2018 payment for the amount due under the Navajo Nation right-of-way lease was $6.9 million , which included amounts due under the Consumer Price Index adjustment, and was used to determine PNM’s operating lease liability as of January 1, 2019. Changes in the Consumer Price Index subsequent to January 1, 2019 are considered variable lease payments. PNM has other prepaid rights-of-way agreements that are not accounted for as leases or recognized as a component of plant in service. PNM reflects the unamortized balance of these prepayments in other deferred charges on the Consolidated Balance Sheets and recognizes amortization expense associated with these agreements in the Consolidated Statement of Earnings over their term. As of December 31, 2019 and 2018, the unamortized balance of these rights-of-ways was $60.2 million and $63.0 million . During the years ended December 31, 2019 , 2018, and 2017, PNM recognized amortization expense associated with these agreements of $3.7 million , $3.8 million , and $3.5 million . Fleet Vehicles and Equipment As of December 31, 2018, all of the Company’s leases of fleet vehicles and equipment were classified as operating leases. Historically, the Company has utilized substantially all of the economic value of its fleet and equipment leases by the end of the lease term. The Company generally has the contractual ability to return its fleet vehicle and equipment leases to the lessor after one year provided the lessor can recover remaining amounts owed under the agreement from third-parties or through make-whole provisions in the contract but does not typically exercise this right. As a result, fleet vehicle and equipment leases commencing on or after January 1, 2019 are classified as financing leases. The Company’s fleet vehicle and equipment lease agreements include non-lease components for insignificant administrative and other costs that are billed over the life of the agreement. The Company has elected to combine these fees with the lease components of the agreement. Certain of the Company’s fleet vehicle and equipment leases contain residual value guarantees. At December 31, 2019 , residual value guarantees on fleet vehicle and equipment leases are $0.7 million , $1.2 million , and $1.9 million for PNM, TNMP, and PNMR. Other The Company holds a number of office space and office equipment leases. The Company’s current office space leases, all of which existed as of December 31, 2018, are classified as operating leases. These agreements include non-lease components for costs such as common area maintenance fees, which the Company has elected to combine with the lease component of the agreements. Certain of the Company’s office space leases are held between the Company’s consolidated subsidiaries and have been eliminated on consolidation. See Note 20. The Company’s office equipment leases are primarily for copiers and other graphics equipment. The Company classifies its office equipment leases existing as of December 31, 2018 as operating leases. Office equipment leases commencing on or after January 1, 2019 are classified as financing leases.

Fair Value Disclosures [Abstract] | |
Fair Value of Derivative and Other Financial Instruments | Fair Value of Derivative and Other Financial Instruments Fair value is defined under GAAP as the price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Fair value is based on current market quotes as available and is supplemented by modeling techniques and assumptions made by the Company to the extent quoted market prices or volatilities are not available. External pricing input availability varies based on commodity location, market liquidity, and term of the agreement. Valuations of derivative assets and liabilities take into account nonperformance risk, including the effect of counterparties’ and the Company’s credit risk. The Company regularly assesses the validity and availability of pricing data for its derivative transactions. Although the Company uses its best judgment in estimating the fair value of these instruments, there are inherent limitations in any estimation technique. Energy Related Derivative Contracts Overview The primary objective for the use of commodity derivative instruments, including energy contracts, options, swaps, and futures, is to manage price risk associated with forecasted purchases of energy and fuel used to generate electricity, as well as managing anticipated generation capacity in excess of forecasted demand from existing customers. PNM’s energy related derivative contracts manage commodity risk. PNM is required to meet the demand and energy needs of its customers. PNM is exposed to market risk for the needs of its customers not covered under a FPPAC. PNM was exposed to market risk for its share of PVNGS Unit 3 through December 31, 2017, at which time PVNGS Unit 3 became a jurisdictional resource to serve New Mexico retail customers. Beginning January 1, 2018, PNM is exposed to market risk for its 65 MW interest in SJGS Unit 4, which is held as merchant plant as ordered by the NMPRC (Note 16). PNM has entered into agreements to sell power from 36 MW of that capacity to a third party at a fixed price for the period January 1, 2018 through May 31, 2022, subject to certain conditions. Under these agreements, PNM is obligated to deliver 36 MW of power only when SJGS Unit 4 is operating. These agreements are not considered derivatives because there is no notional amount due to the unit-contingent nature of the transactions. PNM and Tri-State have a hazard sharing agreement that expires in May 2022. Under this agreement, each party sells the other party 100 MW of capacity and energy from a designated generation resource on a unit contingent basis, subject to certain performance guarantees. Both the purchases and sales are made at the same market index price. This agreement serves to reduce the magnitude of each party’s single largest generating hazard and assists in enhancing the reliability and efficiency of their respective operations. PNM passes the sales and purchases through to customers under PNM’s FPPAC. See Note 17. PNM’s operations are managed primarily through a net asset-backed strategy, whereby PNM’s aggregate net open forward contract position is covered by its forecasted excess generation capabilities or market purchases. PNM could be exposed to market risk if its generation capabilities were to be disrupted or if its load requirements were to be greater than anticipated. If all or a portion of load requirements were required to be covered as a result of such unexpected situations, commitments would have to be met through market purchases. TNMP does not enter into energy related derivative contracts. Commodity Risk Marketing and procurement of energy often involve market risks associated with managing energy commodities and establishing positions in the energy markets, primarily on a short-term basis. PNM routinely enters into various derivative instruments such as forward contracts, option agreements, and price basis swap agreements to economically hedge price and volume risk on power commitments and fuel requirements and to minimize the effect of market fluctuations. PNM monitors the market risk of its commodity contracts in accordance with approved risk and credit policies. Accounting for Derivatives Under derivative accounting and related rules for energy contracts, PNM accounts for its various instruments for the purchase and sale of energy, which meet the definition of a derivative, based on PNM’s intent. During the years ended December 31, 2019 , 2018 , and 2017 , PNM was not hedging its exposure to the variability in future cash flows from commodity derivatives through designated cash flows hedges. The derivative contracts recorded at fair value that do not qualify or are not designated for cash flow hedge accounting are classified as economic hedges. Economic hedges are defined as derivative instruments, including long-term power agreements, used to economically hedge generation assets, purchased power and fuel costs, and customer load requirements. Changes in the fair value of economic hedges are reflected in results of operations and are classified between operating revenues and cost of energy according to the intent of the hedge. PNM has no trading transactions. Commodity Derivatives PNM’s commodity derivative instruments that are recorded at fair value, all of which are accounted for as economic hedges, are presented in the following line items on the Consolidated Balance Sheets: Economic Hedges December 31, 2019 2018 (In thousands) Other current assets $ 1,089 $ 1,083 Other deferred charges 1,507 2,511 2,596 3,594 Other current liabilities (1,089 ) (1,177 ) Other deferred credits (1,507 ) (2,511 ) (2,596 ) (3,688 ) Net $ — $ (94 ) Certain of PNM’s commodity derivative instruments in the above table are subject to master netting agreements whereby assets and liabilities could be offset in the settlement process. PNM does not offset fair value and cash collateral for derivative instruments under master netting arrangements and the above table reflects the gross amounts of fair value assets and liabilities for commodity derivatives. Included in the above table are equal amounts of assets and liabilities aggregating $2.6 million at December 31, 2019 and $3.6 million at December 31, 2018 resulting from PNM’s hazard sharing arrangements with Tri-State (Note 17). The hazard sharing arrangements are net-settled upon delivery. Other amounts that could be offset under master netting agreements were immaterial. At December 31, 2019 and 2018 , PNM had no amounts recognized for the legal right to reclaim cash collateral. However, at December 31, 2019 and 2018 , amounts posted as cash collateral under margin arrangements were $0.5 million and $1.0 million . At December 31, 2019 and 2018 , obligations to return cash collateral were $0.9 million and $1.0 million . Cash collateral amounts are included in other current assets and other current liabilities on the Consolidated Balance Sheets. PNM has a NMPRC-approved hedging plan to manage fuel and purchased power costs related to customers covered by its FPPAC. There were no amounts hedged under this plan as of December 31, 2019 or 2018 . The following table presents the effect of mark-to-market commodity derivative instruments on PNM’s earnings, excluding income tax effects. Commodity derivatives had no impact on OCI for the periods presented. Economic Hedges Year Ended December 31, 2019 2018 2017 (In thousands) Electric operating revenues $ 97 $ (50 ) $ 5,151 Cost of energy (97 ) (52 ) (5,386 ) Total gain (loss) $ — $ (102 ) $ (235 ) Commodity contract volume positions are presented in MMBTU for gas related contracts and in MWh for power related contracts. The table below presents PNM’s net buy (sell) volume positions: Economic Hedges MMBTU MWh December 31, 2019 — — December 31, 2018 100,000 — PNM has contingent requirements to provide collateral under commodity contracts having an objectively determinable collateral provision that are in net liability positions and are not fully collateralized with cash. In connection with managing its commodity risks, PNM enters into master agreements with certain counterparties. If PNM is in a net liability position under an agreement, some agreements provide that the counterparties can request collateral if PNM’s credit rating is downgraded; other agreements provide that the counterparty may request collateral to provide it with “adequate assurance” that PNM will perform; and others have no provision for collateral. At December 31, 2019 and 2018 , PNM had no such contracts in a net liability position. Non-Derivative Financial Instruments The carrying amounts reflected on the Consolidated Balance Sheets approximate fair value for cash, receivables, and payables due to the short period of maturity. Investment securities are carried at fair value. Investment securities consist of PNM assets held in the NDT for its share of decommissioning costs of PVNGS and trusts for PNM’s share of final reclamation costs related to the coal mines serving SJGS and Four Corners. See Note 16. At December 31, 2019 and 2018 , the fair value of investment securities included $336.0 million and $287.1 million for the NDT and $52.8 million and $41.1 million for the coal mine reclamation trusts. Prior to 2018, PNM classified all debt and equity investments held in the NDT and coal mine reclamation trusts as available-for-sale securities. Unrealized losses on these securities were recorded immediately through earnings and unrealized gains were recorded in AOCI until the securities were sold. On January 1, 2018, PNM recorded an after-tax cumulative effect adjustment of $11.2 million to reclassify unrealized holding gains on equity securities held in the NDT and coal mine reclamation trusts from AOCI to retained earnings on the Consolidated Balance Sheets. After January 1, 2018, all gains and losses resulting from sales and changes in the fair value of equity securities are recognized in earnings. Under ASU 2016-01, the Company’s accounting for available-for-sale debt securities remains essentially unchanged. See Note 1 for investment accounting policies and discussion of New Accounting Pronouncements regarding ASU 2016-13. Gains and losses recognized on the Consolidated Statements of Earnings related to investment securities in the NDT and reclamation trusts are presented in the following table: Year ended December 31, 2019 2018 (In thousands) Equity securities: Net gains from equity securities sold $ 5,698 $ 4,864 Net gains (losses) from equity securities still held 18,319 (10,523 ) Total net gains (losses) on equity securities 24,017 (5,659 ) Available-for-sale debt securities: Net gains (losses) on debt securities 5,572 (11,517 ) Net gains (losses) on investment securities $ 29,589 $ (17,176 ) The proceeds and gross realized gains and losses on the disposition of securities held in the NDT and coal mine reclamation trusts are shown in the following table. Realized gains and losses are determined by specific identification of costs of securities sold. Gross realized losses shown below exclude the (increase)/decrease in realized impairment losses of $3.0 million , $(9.4) million , and $3.3 million for the years ended December 31, 2019 , 2018 and 2017 . Year Ended December 31, 2019 2018 2017 (In thousands) Proceeds from sales $ 494,528 $ 984,533 $ 637,492 Gross realized gains $ 25,760 $ 19,358 $ 36,896 Gross realized (losses) $ (17,453 ) $ (16,624 ) $ (12,993 ) Held-to-maturity securities are those investments in debt securities that the Company has the ability and intent to hold until maturity. At December 31, 2017, PNMR’s held-to-maturity securities consisted of the Westmoreland Loan. In May 2018, the full amount owed under the Westmoreland Loan was repaid (Note 16). The Company has no available-for-sale debt securities for which carrying value exceeds fair value. There are no impairments considered to be “other than temporary” that are included in AOCI and not recognized in earnings. At December 31, 2019 , the available-for-sale debt securities held by PNM, had the following final maturities: Fair Value (In thousands) Within 1 year $ 20,148 After 1 year through 5 years 80,052 After 5 years through 10 years 84,603 After 10 years through 15 years 13,090 After 15 years through 20 years 11,950 After 20 years 39,975 $ 249,818 Fair Value Disclosures The Company determines the fair values of its derivative and other financial instruments based on the hierarchy established in GAAP, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. GAAP describes three levels of inputs that may be used to measure fair value. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability. The Company records any transfers between fair value hierarchy levels as of the end of each calendar quarter. There were no transfers between levels during the year ended December 31, 2018 . See New Accounting Pronouncements in Note 1. For investment securities, Level 2 and Level 3 fair values are provided by fund managers utilizing a pricing service. For Level 2 fair values, the pricing provider predominantly uses the market approach using bid side market value based upon a hierarchy of information for specific securities or securities with similar characteristics. Fair values of Level 2 investments in mutual funds are equal to net asset value. Level 3 investments at December 31, 2018 were comprised of corporate term loans. For commodity derivatives, Level 2 fair values are determined based on market observable inputs, which are validated using multiple broker quotes, including forward price, volatility, and interest rate curves to establish expectations of future prices. Credit valuation adjustments are made for estimated credit losses based on the overall exposure to each counterparty. For the Company’s long-term debt, Level 2 fair values are provided by an external pricing service. The pricing service primarily utilizes quoted prices for similar debt in active markets when determining fair value. The valuation of Level 3 investments requires significant judgment by the pricing provider due to the absence of quoted market values, changes in market conditions, and the long-term nature of the assets. The significant unobservable inputs include the trading multiples of public companies that are considered comparable to the company being valued, company specific issues, estimates of liquidation value, current operating performance and future expectations of performance, changes in market outlook and the financing environment, capitalization rates, discount rates, and cash flows.

Investments Held by Employee Benefit Plans As discussed in Note 11, PNM and TNMP have trusts that hold investment assets for their pension and other postretirement benefit plans. The fair value of the assets held by the trusts impacts the determination of the funded status of each plan but the assets are not reflected on the Company’s Consolidated Balance Sheets. Both the PNM Pension Plan and the TNMP Pension Plan hold units of participation in the PNM Resources, Inc. Master Trust (the “PNMR Master Trust”), which was established for the investment of assets of the pension plans. The Company’s investment allocation targets in 2019 consist of 30% equities, 20% alternative investments (both of which are considered return generating), and 50% fixed income. GAAP provides a practical expedient that allows the net asset value per share to be used as fair value for investments in certain entities that do not have readily determinable fair values and are considered to be investment companies. Fair values for alternative investments held by the PNMR Master Trust are valued using this practical expedient. Under GAAP, investments for which fair value is measured using that practical expedient are not required to be categorized within the fair value hierarchy. Level 2 and Level 3 fair values are provided by fund managers utilizing a pricing service. For level 2 fair values, the pricing provider predominately uses the market approach using bid side market value based upon a hierarchy of information for specific securities or securities with similar characteristics. Fair values of Level 2 investments in mutual funds are equal to net asset value as of year-end. Level 3 investments at December 31, 2018 were comprised of corporate term loans. Fair value prices for Level 2 corporate term loans predominately use the market approach which uses bid side market values based upon hierarchy information for specific securities or securities with similar characteristics. Alternative investments include private equity funds, hedge funds, and real estate funds. The private equity funds are not voluntarily redeemable. These investments are realized through periodic distributions occurring over a 10 to 15 years term after the initial investment. The real estate funds and hedge funds may be voluntarily redeemed but are subject to redemption provisions that may result in the funds not being redeemable in the near term. Audited financial statements are received for each fund and are reviewed by the Company annually. The valuation of Level 3 investments and alternative investments requires significant judgment by the pricing provider due to the absence of quoted market values, changes in market conditions, and the long-term nature of the assets. The significant unobservable inputs include the trading multiples of public companies that are considered comparable to the company being valued, company specific issues, estimates of liquidation value, current operating performance and future expectations of performance, changes in market outlook and the financing environment, capitalization rates, discount rates, and cash flows. Neither the employee benefit plans nor the PNMR Master Trust have any Level 3 investments as of December 31, 2019.

Variable Interest Entities [Abstract] | |
Variable Interest Entities | Variable Interest Entities GAAP determines how an enterprise evaluates and accounts for its involvement with variable interest entities, focusing primarily on whether the enterprise has the power to direct the activities that most significantly impact the economic performance of a variable interest entity (“VIE”). GAAP also requires continual reassessment of the primary beneficiary of a VIE. Valencia PNM has a PPA to purchase all of the electric capacity and energy from Valencia, a 158 MW natural gas-fired power plant near Belen, New Mexico, through May 2028. A third party built, owns, and operates the facility while PNM is the sole purchaser of the electricity generated. PNM is obligated to pay fixed operation and maintenance and capacity charges in addition to variable operation and maintenance charges under this PPA. For the years ended December 31, 2019 , 2018 , and 2017 , PNM paid $19.9 million , $19.6 million , and $19.6 million for fixed charges and $1.2 million , $1.4 million , and $1.3 million for variable charges. PNM does not have any other financial obligations related to Valencia. The assets of Valencia can only be used to satisfy its obligations and creditors of Valencia do not have any recourse against PNM’s assets. During the term of the PPA, PNM has the option, under certain conditions, to purchase and own up to 50% of the plant or the VIE. The PPA specifies that the purchase price would be the greater of 50% of book value reduced by related indebtedness or 50% of fair market value. PNM sources fuel for the plant, controls when the facility operates through its dispatch, and receives the entire output of the plant, which factors directly and significantly impact the economic performance of Valencia. Therefore, PNM has concluded that the third-party entity that owns Valencia is a VIE and that PNM is the primary beneficiary of the entity under GAAP since PNM has the power to direct the activities that most significantly impact the economic performance of Valencia and will absorb the majority of the variability in the cash flows of the plant. As the primary beneficiary, PNM consolidates Valencia in its financial statements. Accordingly, the assets, liabilities, operating expenses, and cash flows of Valencia are included in the Consolidated Financial Statements of PNM although PNM has no legal ownership interest or voting control of the VIE. The assets and liabilities of Valencia set forth below are immaterial to PNM and, therefore, not shown separately on the Consolidated Balance Sheets. The owner’s equity and net income of Valencia are considered attributable to non-controlling interest. Summarized financial information for Valencia is as follows: Results of Operations Year Ended December 31 2019 2018 2017 (In thousands) Operating revenues $ 21,073 $ 21,025 $ 20,887 Operating expenses (6,832 ) (5,913 ) (5,870 ) Earnings attributable to non-controlling interest $ 14,241 $ 15,112 $ 15,017 Financial Position December 31, 2019 2018 (In thousands) Current assets $ 5,094 $ 2,684 Net property, plant and equipment 58,581 62,066 Total assets 63,675 64,750 Current liabilities 623 538 Owners’ equity – non-controlling interest $ 63,052 $ 64,212 Westmoreland San Juan Mining, LLC As discussed in the subheading Coal Supply in Note 16, PNM purchases coal for SJGS under a coal supply agreement (“SJGS CSA”). That section includes information on the acquisition of SJCC by WSJ, a subsidiary of Westmoreland Coal Company (“Westmoreland”), on January 31, 2016, as well as the $125.0 million loan (the “Westmoreland Loan”) from NM Capital, a subsidiary of PNMR, to WSJ, which loan provided substantially all of the funds required for the purchase of SJCC. On May 22, 2018, the full principal outstanding under the Westmoreland Loan was repaid. NM Capital used a portion of the proceeds to repay all remaining amounts owed under the BTMU Term Loan. These payments effectively terminated the loan agreements and PNMR’s guarantee of NM Capital’s obligations under the BTMU Term Loan. Prior to its repayment, the Westmoreland Loan resulted in PNMR being considered to have a variable interest in WSJ, including its subsidiary, SJCC, since PNMR and NM Capital were subject to possible loss in the event of default of WSJ. On October 9, 2018, Westmoreland filed a Current Report on Form 8-K with the SEC announcing it had filed voluntary petitions for relief under Chapter 11 of the U.S. Bankruptcy Code. On March 15, 2019, Westmoreland emerged from Chapter 11 bankruptcy as a privately held company owned and operated by a group of its former creditors. Under the reorganization, the assets of SJCC were sold to Westmoreland San Juan Mining, LLC (“WSJ LLC”), a subsidiary of Westmoreland Mining Holdings, LLC. As successor entity to SJCC, WSJ LLC assumed all rights and obligations of WSJ including obligations to PNM under the SJGS CSA and to PNMR under a letter of credit support agreement. See Note 16. PNMR issued $30.3 million in letters of credit to facilitate the issuance of reclamation bonds required in order for SJCC to mine coal to be supplied to SJGS. As discussed above, WSJ LLC assumed the rights and obligations of SJCC, including obligations to PNMR for the letters of credit. The letters of credit support results in PNMR having a variable interest in WSJ LLC since PNMR is subject to possible loss in the event performance by PNMR is required under the letters of credit support. PNMR considers the possibility of loss under the letters of credit support to be remote since the purpose of posting the bonds is to provide assurance that WSJ LLC performs the required reclamation of the mine site in accordance with applicable regulations and all reclamation costs are reimbursable under the SJGS CSA. Also, much of the mine reclamation activities will not be performed until after the expiration of the SJGS CSA. In addition, each of the SJGS participants has established and actively fund trusts to meet future reclamation obligations. WSJ LLC is considered to be a VIE. PNMR’s analysis of its arrangements with WSJ LLC concluded that WSJ LLC has the ability to direct its mining operations, which is the factor that most significantly impacts the economic performance of WSJ LLC. Other than PNM being able to ensure that coal is supplied in adequate quantities and of sufficient quality to provide the fuel necessary to operate SJGS in a normal manner, the mining operations are solely under the control of WSJ LLC, including developing mining plans, hiring of personnel, and incurring operating and maintenance expenses. Neither PNMR nor PNM has any ability to direct or influence the mining operation. PNM’s involvement through the SJGS CSA, which was assumed by WSJ LLC pursuant to the March 15, 2019 purchase of the assets owned by SJCC by WSJ LLC, is a protective right rather than a participating right and WSJ LLC has the power to direct the activities that most significantly impact the economic performance of WSJ LLC. The SJGS CSA requires WSJ LLC to deliver coal required to fuel SJGS in exchange for payment of a set price per ton, which is escalated over time for inflation. If WSJ LLC is able to mine more efficiently than anticipated, its economic performance will be improved. Conversely, if WSJ LLC cannot mine as efficiently as anticipated, its economic performance will be negatively impacted. Accordingly, PNMR believes WSJ LLC is the primary beneficiary and, therefore, WSJ LLC is not consolidated by either PNMR or PNM. The amounts outstanding under the letters of credit support constitute PNMR’s maximum exposure to loss from the VIE at December 31, 2019. |
Pension and Other Postretiremen
Pension and Other Postretirement Benefits | 12 Months Ended |

Retirement Benefits [Abstract] | |
Pension and Other Postretirement Benefits | Pension and Other Postretirement Benefits PNMR and its subsidiaries maintain qualified defined benefit pension plans, postretirement benefit plans providing medical and dental benefits, and executive retirement programs (collectively, the “PNM Plans” and “TNMP Plans”). PNMR maintains the legal obligation for the benefits owed to participants under these plans. The periodic costs or income of the PNM Plans and TNMP Plans are included in regulated rates to the extent attributable to regulated operations. PNM and TNMP receive a regulated return on the amounts funded for pension and OPEB plans in excess of the periodic cost or income to the extent included in retail rates (a “prepaid pension asset”). Participants in the PNM Plans include eligible employees and retirees of PNMR and PNM. Participants in the TNMP Plans include eligible employees and retirees of TNMP. The PNM pension plan was frozen at the end of 1997 with regard to new participants, salary levels, and benefits. Through December 31, 2007, additional credited service could be accrued under the PNM pension plan up to a limit determined by age and service. The TNMP pension plan was frozen at December 31, 2005 with regard to new participants, salary levels, and benefits. GAAP requires a plan sponsor to (a) recognize in its statement of financial position an asset for a plan’s overfunded status or a liability for a plan’s underfunded status; (b) measure a plan’s assets and its obligations that determine its funded status as of the end of the employer’s fiscal year; and (c) recognize changes in the funded status of a defined benefit postretirement plan in the year in which the changes occur. GAAP requires unrecognized prior service costs and unrecognized gains or losses to be recorded in AOCI and subsequently amortized. To the extent the amortization of these items will ultimately be recovered or returned through future rates, PNM and TNMP record the costs as a regulatory asset or regulatory liability. The amortization of these incurred costs is included as pension and postretirement benefit periodic cost or income in subsequent years. The Company maintains trust funds for the pension and OPEB plans from which benefits are paid to eligible employees and retirees. The Company’s funding policy is to make contributions to the trusts, as determined by an independent actuary, that comply with minimum guidelines of the Employee Retirement Income Security Act and the IRC. Information concerning the investments is contained in Note 9. The Company has in place a policy that defines the investment objectives, establishes performance goals of asset managers, and provides procedures for the manner in which investments are to be reviewed. The plans implement investment strategies to achieve the following objectives: • Implement investment strategies commensurate with the risk that the Corporate Investment Committee deems appropriate to meet the obligations of the pension plans and OPEB plans, minimize the volatility of expense, and account for contingencies • Transition asset mix over the long-term to a higher proportion of high-quality fixed income investments as the plans’ funded statuses improve Management is responsible for the determination of the asset target mix and the expected rate of return. The target asset allocations are determined based on consultations with external investment advisors. The expected long-term rate of return on pension and postretirement plan assets is calculated on the market-related value of assets. GAAP requires that actual gains and losses on pension and OPEB plan assets be recognized in the market-related value of assets equally over a period of not more than five years, which reduces year-to-year volatility. For the PNM Plans and TNMP Plans, the market-related value of assets is equal to the prior year’s market-related value of assets adjusted for contributions, benefit payments and investment gains and losses that are within a corridor of plus or minus 4.0% around the expected return on market value. Gains and losses that are outside the corridor are amortized over five years . In March 2017, the FASB issued Accounting Standards Update 2017-07 - Compensation - Retirement Benefits (Topic 715) to improve the presentation of net periodic pension and other postretirement benefit costs. Prior to ASU 2017-07, the Company presented all of its net periodic benefit costs, net of amounts capitalized to construction and other accounts, as administrative and general expenses on its statements of earnings. ASU 2017-07 requires the service cost component of net benefit costs be presented in the same line item or items as employees’ compensation. The other components of net periodic benefit cost (the “non-service cost components”) are required to be presented separately from the service cost component and outside of operating income. ASU 2017-07 also limits capitalization of net periodic benefit costs to only the service cost component. ASU 2017-07 requires retrospective presentation of the service and non-service cost components of net periodic benefit costs in the income statement and prospective application regarding the capitalization of only the service cost component of net periodic benefit costs. The Company adopted ASU 2017-07 as of January 1, 2018, its required effective date. In accordance with the standard, the PNM and PNMR Consolidated Statements of Earnings reflect a reclassification from administrative and general expenses to other (deductions) for the non-service cost components of net periodic benefit costs in the amount of $8.6 million , net of amounts capitalized prior to the adoption of the standard, in the year ended December 31, 2017. The non-service components of TNMP’s net periodic benefit costs in 2017 were insignificant. The Company believes PNM and TNMP can continue to capitalize the non-service cost components of net periodic benefit costs as regulatory assets and liabilities to the extent attributable to regulated operations. See Note 13. See New Accounting Pronouncements in Note 1 regarding updates to disclosure requirements that will be effective in future periods. Pension Plans For defined benefit pension plans, including the executive retirement plans, the PBO represents the actuarial present value of all benefits attributed by the pension benefit formula to employee service rendered prior to that date using assumptions regarding future compensation levels. The ABO represents the PBO without considering future compensation levels. Since the pension plans are frozen, the PBO and ABO are equal. The following table presents information about the PBO, fair value of plan assets, and funded status of the plans: PNM TNMP Year Ended December 31, Year Ended December 31, 2019 2018 2019 2018 (In thousands) PBO at beginning of year $ 564,258 $ 623,983 $ 60,587 $ 68,423 Service cost — — — — Interest cost 25,175 24,270 2,686 2,625 Actuarial (gain) loss 61,151 (41,025 ) 7,889 (5,216 ) Benefits paid (44,839 ) (42,970 ) (5,588 ) (5,245 ) PBO at end of year 605,745 564,258 65,574 60,587 Fair value of plan assets at beginning of year 489,978 562,016 55,074 63,499 Actual return on plan assets 86,328 (29,068 ) 9,881 (3,180 ) Employer contributions — — — — Benefits paid (44,839 ) (42,970 ) (5,588 ) (5,245 ) Fair value of plan assets at end of year 531,467 489,978 59,367 55,074 Funded status – asset (liability) for pension benefits $ (74,278 ) $ (74,280 ) $ (6,207 ) $ (5,513 ) Actuarial (gain) loss results from changes in: PNM TNMP Year Ended December 31, Year Ended December 31, 2019 2018 2019 2018 (in thousands) Discount rates $ 66,108 $ (34,769 ) $ 8,006 $ (4,278 ) Demographic experience (732 ) 431 394 (301 ) Mortality rate (4,225 ) (6,966 ) (296 ) (705 ) Other assumptions and experience — 279 (215 ) 68 $ 61,151 $ (41,025 ) $ 7,889 $ (5,216 ) The following table presents pre-tax information about net actuarial (gain) loss in AOCI as of December 31, 2019 .

The expected long-term rate of return on plan assets reflects the average rate of earnings expected on the funds invested, or to be invested, to provide for the benefits included in the PBO. Factors that are considered include, but are not limited to, historic returns on plan assets, current market information on long-term returns (e.g., long-term bond rates) and current and target asset allocations between asset categories. If all other factors were to remain unchanged, a 1% decrease in the expected long-term rate of return would cause PNM’s and TNMP’s 2020 net periodic benefit cost to increase $5.0 million and $0.6 million (analogous changes would result from a 1% increase). The actual rate of return for the PNM and TNMP pension plans was 18.5% and 18.9% for the year ended December 31, 2019 . The Company’s long-term pension investment strategy is to invest in assets whose interest rate sensitivity is correlated with the pension liability. The Company uses an investment strategy, known as Liability Driven Investing, that increases the liability matching investments as the funded status of the pension plans improve. The Company’s investment allocation targets consist of 30% equities, 20% alternative investments (both of which are considered return generating), and 50% fixed income. Equity investments are primarily in domestic securities that include large-, mid-, and small-capitalization companies. The pension plans have a 7% targeted allocation to equities of companies domiciled primarily in developed countries outside of the U.S. The equity investments category includes actively managed international and domestic equity securities that are benchmarked against a variety of style indices. Fixed income investments are primarily corporate bonds of companies from diversified industries and government securities. Alternative investments include investments in hedge funds, real estate funds, and private equity funds. The hedge funds and private equity funds are structured as multi-manager multi-strategy fund of funds to achieve a diversified position in these asset classes. The hedge funds pursue various absolute return strategies such as relative value, long-short equity, and event driven. Private equity fund strategies include mezzanine financing, buy-outs, and venture capital. The real estate investments are commingled real estate portfolios that invest in a diversified portfolio of assets including commercial property and multi-family housing. See Note 9 for fair value information concerning assets held by the pension plans. The following pension benefit payments are expected to be paid: PNM TNMP (In thousands) 2020 $ 46,600 $ 5,321 2021 45,636 5,244 2022 44,702 5,111 2023 43,595 4,895 2024 42,637 4,652 2025 - 2029 193,885 20,846 Based on current law, funding requirements, and estimates of portfolio performance, the Company does no t expect to make any cash contributions to the pension plans in 2020 or 2021. PNM and TNMP expect to contribute $4.6 million and zero to the PNM and TNMP pension plans in 2022, $19.1 million and $1.1 million in 2023, and $19.0 million and $2.8 million in 2024. The funding assumptions were developed using discount rates of 3.4% to 3.5% . Actual amounts to be funded in the future will be dependent on the actuarial assumptions at that time, including the appropriate discount rates. PNM and TNMP may make additional contributions at their discretion. Other Postretirement Benefit Plans For postretirement benefit plans, the APBO is the actuarial present value of all future benefits attributed under the terms of the postretirement benefit plan to employee service rendered to date. The following table presents information about the APBO, the fair value of plan assets, and the funded status of the plans: PNM TNMP Year Ended December 31, Year Ended December 31, 2019 2018 2019 2018 (In thousands) APBO at beginning of year $ 75,305 $ 89,897 $ 10,064 $ 12,279 Service cost 53 83 50 134 Interest cost 3,316 3,439 451 477 Participant contributions 2,131 2,390 316 174 Actuarial (gain) loss 2,587 (12,206 ) 1,004 (2,213 ) Benefits paid (8,271 ) (8,298 ) (650 ) (787 ) APBO at end of year 75,121 75,305 11,235 10,064 Fair value of plan assets at beginning of year 69,703 80,356 8,744 10,002 Actual return on plan assets 19,257 (7,669 ) 2,434 (988 ) Employer contributions 3,580 2,924 — 343 Participant contributions 2,131 2,390 316 174 Benefits paid (8,271 ) (8,298 ) (650 ) (787 ) Fair value of plan assets at end of year 86,400 69,703 10,844 8,744 Funded status – asset (liability) $ 11,279 $ (5,602 ) $ (391 ) $ (1,320 ) As of December 31, 2019, the fair value of plan assets exceeds the APBO for PNM’s OPEB Plan and the resulting net asset is presented in other deferred charges on the Consolidated Balance Sheets.

For the TNMP OPEB plan, actuarial gains of $0.9 million were recorded as adjustments to regulatory liabilities. The following table presents the components of net periodic benefit cost (income): Year Ended December 31, 2019 2018 2017 (In thousands) PNM Service cost $ 53 $ 83 $ 96 Interest cost 3,316 3,439 4,025 Expected return on plan assets (5,278 ) (5,414 ) (5,230 ) Amortization of net (gain) loss 675 2,354 3,682 Amortization of prior service credit (397 ) (1,664 ) (1,663 ) Net periodic benefit cost (income) $ (1,631 ) $ (1,202 ) $ 910 TNMP Service cost $ 50 $ 134 $ 143 Interest cost 451 477 556 Expected return on plan assets (517 ) (542 ) (456 ) Amortization of net (gain) loss (444 ) (227 ) (79 ) Amortization of prior service cost — — — Net periodic benefit cost (income) $ (460 ) $ (158 ) $ 164 The following significant weighted-average assumptions were used to determine the APBO and net periodic benefit cost. Should actual experience differ from actuarial assumptions, the APBO and net periodic benefit cost would be affected. Year Ended December 31, PNM 2019 2018 2017 Discount rate for determining December 31 APBO 3.42 % 4.63 % 4.00 % Discount rate for determining net periodic benefit cost 4.63 % 4.00 % 4.47 % Expected return on plan assets 7.20 % 7.42 % 7.50 % Rate of compensation increase N/A N/A N/A TNMP Discount rate for determining December 31 APBO 3.42 % 4.63 % 4.00 % Discount rate for determining net periodic benefit cost 4.63 % 4.00 % 4.47 % Expected return on plan assets 5.80 % 5.86 % 5.40 % Rate of compensation increase N/A N/A N/A The assumed discount rate for determining the APBO was determined based on a review of long-term high-grade bonds and management’s expectations. The expected long-term rate of return on plan assets reflects the average rate of earnings expected on the funds invested, or to be invested, to provide for the benefits included in the APBO. Factors that are considered include, but are not limited to, historic returns on plan assets, current market information on long-term returns (e.g., long-term bond rates), and current and target asset allocations between asset categories. If all other factors were to remain unchanged, a 1% decrease in the expected long-term rate of return would cause PNM’s and TNMP’s 2020 net periodic benefit cost to increase $0.8 million and $0.1 million (analogous changes would result from a 1% increase). The actual rate of return for the PNM and TNMP OPEB plans was 28.1% and 28.4% for the year ended December 31, 2019 . The following table shows the assumed health care cost trend rates for the PNM OPEB plan: PNM December 31, 2019 2018 Health care cost trend rate assumed for next year 6.5 % 6.5 % Rate to which the cost trend rate is assumed to decline (the ultimate trend rate) 5.0 % 5.0 % Year that the rate reaches the ultimate trend rate 2026 2026 The following table shows the impact of a one-percentage-point change in assumed health care cost trend rates: PNM 1-Percentage- Point Increase 1-Percentage- Point Decrease (In thousands) Effect on total of service and interest cost $ 55 $ (77 ) Effect on APBO $ 1,310 $ (1,744 ) TNMP’s exposure to cost increases in the OPEB plan is minimized by a provision that limits TNMP’s share of costs under the plan. Costs of the plan in excess of the limit, which was reached at the end of 2001, are wholly borne by the participants. As a result, a one-percentage-point change in assumed health care cost trend rates would have no effect on either the net periodic expense or the year-end APBO. Effective January 1, 2018, the PNM OPEB plan was amended to limit the annual increase in the Company’s costs to 5% . Increases in excess of the limit are born by the PNM OPEB plan participants. The Company’s OPEB plans invest in a portfolio that is diversified by asset class and style strategies. The OPEB plans generally use the same pension fixed income and equity investment managers and utilize the same overall investment strategy as described above for the pension plans, except there is no allocation to alternative investments. The OPEB plans have a target asset allocation of 70% equities and 30% fixed income. See Note 9 for fair value information concerning assets held by the other postretirement benefit plans. The following OPEB payments, which reflect expected future service and are net of participant contributions, are expected to be paid: PNM TNMP (In thousands) 2020 $ 6,770 $ 647 2021 6,584 670 2022 6,216 695 2023 6,017 709 2024 5,755 719 2025 - 2029 24,122 3,497 PNM and TNMP made no cash contributions to the OPEB trusts in 2019 or 2018 and PNM and TNMP do no t expect to make cash contributions to the OPEB trusts in 2020-2024. However, a portion of the disbursements attributable to the OPEB trust are paid by PNM and are therefore considered to be contributions to the PNM OPEB plan. Payments by PNM on behalf of the PNM OPEB plan are expected to be $3.7 million in 2020 and $13.5 million in 2021-2024.

The impacts of changes in assumptions or experience were not significant. Disbursements under the executive retirement program, funded by PNM and TNMP, which are considered to be contributions to the plan were $1.4 million and $0.1 million in the year ended December 31, 2019 and $1.5 million and $0.1 million for the year ended December 31, 2018. The following executive retirement plan payments, which reflect expected future service, are expected: PNM TNMP (In thousands) 2020 $ 1,459 $ 93 2021 1,424 90 2022 1,383 86 2023 1,335 82 2024 1,280 76 2025 - 2029 5,419 273 Other Retirement Plans PNMR sponsors a 401(k) defined contribution plan for eligible employees, including those of its subsidiaries. PNMR’s contributions to the 401(k) plan consist of a discretionary matching contribution equal to 75% of the first 6% of eligible compensation contributed by the employee on a before-tax basis. PNMR also makes a non-matching contribution ranging from 3% to 10% of eligible compensation based on the eligible employee’s age. PNMR also provides executive deferred compensation benefits through an unfunded, non-qualified plan. The purpose of this plan is to permit certain key employees of PNMR who participate in the 401(k) defined contribution plan to defer compensation and receive credits without reference to the certain limitations on contributions. A summary of expenses for these other retirement plans is as follows: Year Ended December 31, 2019 2018 2017 (In thousands) PNMR 401(k) plan $ 16,097 $ 16,677 $ 16,452 Non-qualified plan $ 4,551 $ 865 $ 3,702 PNM 401(k) plan $ 11,587 $ 12,052 $ 12,120 Non-qualified plan $ 3,384 $ 621 $ 2,834 TNMP 401(k) plan $ 4,511 $ 4,625 $ 4,332 Non-qualified plan $ 1,167 $ 244 $ 868 |
Stock-Based Compensation
Stock-Based Compensation | 12 Months Ended |

Share-based Payment Arrangement [Abstract] | |
Stock-Based Compensation | Stock-Based Compensation PNMR has various stock-based compensation programs, including stock options, restricted stock, and performance shares granted under the Performance Equity Plan (“PEP”). Although certain PNM and TNMP employees participate in the PNMR plans, PNM and TNMP do not have separate employee stock-based compensation plans. The Company has not awarded stock options since 2010 and all employee stock options expired or were exercised in February 2020. Certain restricted stock awards are subject to achieving performance or market targets. Other awards of restricted stock are only subject to time vesting requirements. Performance Equity Plan The PEP provides for the granting of non-qualified stock options, restricted stock rights, performance shares, performance units, and stock appreciation rights to officers, key employees, and non-employee members of the Board. Restricted stock under the PEP refers to awards of stock subject to vesting, performance, or market conditions rather than to shares with contractual post-vesting restrictions. Generally, the awards vest ratably over three years from the grant date of the award. However, awards with performance or market conditions vest upon satisfaction of those conditions. In addition, plan provisions provide that upon retirement, participants become 100% vested in certain stock awards. The vesting period for awards of restricted stock to non-employee members of the Board is one year . The total number of shares of PNMR common stock subject to all awards under the PEP, as approved by PNMR’s shareholders in May 2014, may not exceed 13.5 million shares, subject to adjustment and certain share counting rules set forth in the PEP. This current share pool is charged five shares for each share subject to restricted stock or other full value award. Source of Shares The source of shares for exercised stock options and vested restricted stock is shares acquired on the open market by an independent agent, rather than newly issued shares. Accounting for Stock Awards The stock-based compensation expense related to restricted stock awards without performance or market conditions to participants that are retirement eligible on the grant date is recognized immediately at the grant date and is not amortized. Compensation expense for other such awards is amortized to compensation expense over the shorter of the requisite vesting period or the period until the participant becomes retirement eligible. Compensation expense for performance-based shares is recognized ratably over the performance period as required service is provided and is adjusted periodically to reflect the level of achievement expected to be attained. Compensation expense related to market-based shares is recognized ratably over the measurement period, regardless of the actual level of achievement, provided the employees meet their service requirements. Total compensation expense for stock-based payment arrangements recognized by PNMR for the years ended December 31, 2019 , 2018 , and 2017 was $6.4 million , $7.1 million , and $6.2 million . Stock compensation expense of $4.2 million , $4.9 million , and $4.4 million was charged to PNM and $2.2 million , $2.2 million , and $1.8 million was charged to TNMP. At December 31, 2019 , PNMR had unrecognized compensation expense related to stock awards of $3.5 million , which is expected to be recognized over an average of 1.52 years. PNMR receives a tax deduction for certain stock option exercises during the period the options are exercised, generally for the excess of the price at which the options are sold over the exercise prices of the options, and a tax deduction for the value of restricted stock at the vesting date. GAAP requires that all excess tax benefits and deficiencies be recorded to tax expense and classified as operating cash flows when used to reduce taxes payable. The Company adopted Accounting Standards Update 2016-09 – Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting on January 1, 2017, its required effective date. ASU 2016-09 requires that all excess tax benefits and deficiencies be recorded to tax expense and, to the extent affect taxes payable, be classified as cash flows from operating activities. As required by ASU 2016-09, PNMR recorded the excess tax benefits that were not recognized in prior years, due to its net operating loss position, as a cumulative effect adjustment of $10.4 million on January 1, 2017, increasing retained earnings and decreasing accumulated deferred income taxes on the Consolidated Balance Sheets. Year Ended December 31, Excess Tax Benefits 2019 2018 2017 (In thousands) PNM $ 559 $ 1,007 $ 1,708 TNMP 236 377 616 PNMR 795 1,384 2,324 TNMP used excess tax benefits to reduce income taxes payable and the benefit was reflected in cash flows from operating activities. The benefit of excess tax benefits at PNM and PNMR will be reflected in operating cash flows when they reduce income taxes payable. The grant date fair value for restricted stock and stock awards with Company internal performance targets is determined based on the market price of PNMR common stock on the date of the agreements reduced by the present value of future dividends that will not be received prior to vesting. The grant date fair value is applied to the total number of shares that are anticipated to vest, although the number of performance shares that ultimately vest cannot be determined until after the performance periods end. The grant date fair value of stock awards with market targets is determined using Monte Carlo simulation models, which provide grant date fair values that include an expectation of the number of shares to vest at the end of the measurement period. The following table summarizes the weighted-average assumptions used to determine the awards grant date fair value: Year Ended December 31, Restricted Shares and Performance-Based Shares 2019 2018 2017 Expected quarterly dividends per share $ 0.2900 $ 0.2650 $ 0.2425 Risk-free interest rate 2.47 % 2.38 % 1.50 % Market-Based Shares Dividend yield 2.59 % 2.96 % 2.67 % Expected volatility 19.55 % 19.12 % 20.80 % Risk-free interest rate 2.51 % 2.36 % 1.54 % The following table summarizes activity in restricted stock awards, including performance-based and market-based shares, and stock options: Restricted Stock Stock Options Shares Weighted-Average Grant Date Fair Value Shares Weighted Average Exercise Price Outstanding at December 31, 2018 166,651 $ 32.93 81,000 $ 11.94 Granted 134,573 37.92 — — Exercised (138,001 ) 31.44 (79,000 ) 11.93 Forfeited (1,681 ) 39.61 — — Expired — — — — Outstanding at December 31, 2019 161,542 $ 38.21 2,000 $ 12.22 PNMR’s current stock-based compensation program provides for performance and market targets through 2022. In February 2019, the Board approved amendments to exclude certain impacts of the Tax Act on performance metrics for the performance periods ending in 2018 and 2019. These amendments did not impact the Company’s calculation of grant date fair values under the plans but did increase actual achievement levels for the performance period ending in 2018 from below “threshold” levels to below “target” levels and anticipated achievement levels for the performance period ending in 2019 from below “target” levels to the “maximum” levels. As a result of these amendments for the year ended December 31, 2018, the Company recorded additional pre-tax expense of $1.0 million , of which $0.7 million was allocated to PNM and $0.3 million was allocated to TNMP. Included as granted and exercised in the table above are 47,279 previously awarded shares that were earned for the 2016 - 2018 performance measurement period and ratified by the Board in February 2019 (based upon achieving market targets at below “threshold” levels, weighted at 40% , and performance targets at above “target” levels, together weighted at 60% ). Excluded from the above table are 122,277 previously awarded shares that were earned for the 2017 - 2019 performance measurement period and ratified by the Board in February 2020 (based upon achieving market and performance targets at near “maximum” levels). Also excluded from the table above are 150,543 and 147,202 shares for the three -year performance periods ending in 2020 and 2021 that will be awarded if all performance and market criteria are achieved at maximum levels and all executives remain eligible. Effective as of January 1, 2015, the Company entered into a retention award agreement with its then Executive Vice President and Chief Financial Officer under which he would receive awards of restricted stock if PNMR met specified performance targets at the end of 2016 and 2017 and he remained an employee of the Company. The retention award was made under the PEP and was approved by the Board on December 9, 2014. The specified performance target was achieved at the end of 2016 and the Board ratified him receiving $100,000 of PNMR common stock in February 2017 based on a market per share value of $36.30 on the grant date of March 3, 2017, or 2,754 shares. Similarly, if PNMR achieved the specified performance target for the period from January 1, 2015 through December 31, 2017, he was to receive $275,000 of PNMR common stock based on the market value per share on the grant date in early 2018. The specified performance target was achieved at the end of 2017 and the Board ratified him receiving $275,000 of PNMR common stock in February 2018 based on a market value per share of $35.85 on the grant date of March 2, 2018, or 7,670 shares. In 2015, the Company entered into an additional retention award agreement with its Chairman, President, and Chief Executive Officer under which she would receive a total 53,859 shares of PNMR’s common stock if PNMR meets certain performance targets at the end of 2017 and 2019 and she remains an employee of the Company. The retention award was made under the PEP and was approved by the Board on February 26, 2015. The specified performance target was achieved at the end of 2017 and the Board ratified her receiving 17,953 shares in February 2018. The second portion of the 2015 agreement of 35,906 shares was achieved at the end of 2019 and the Board ratified her receiving the shares in February 2020. The above table does not include any restricted stock shares that remain unvested under this retention award agreement. At December 31, 2019 , the aggregate intrinsic value of stock options outstanding, all of which are exercisable, was less than $0.1 million . All the options were exercised or expired in February 2020. At December 31, 2019 , no outstanding stock options had an exercise price greater than the closing price of PNMR common stock on that date. The following table provides additional information concerning restricted stock activity, including performance-based and market-based shares, and stock options: Year Ended December 31, Restricted Stock 2019 2018 2017 Weighted-average grant date fair value $ 37.92 $ 29.65 $ 23.06 Total fair value of restricted shares that vested (in thousands) $ 6,246 $ 8,558 $ 5,747 Stock Options Total intrinsic value of options exercised (in thousands) $ 2,617 $ 3,117 $ 2,234 |

Regulated Operations [Abstract] | |
Regulatory Assets and Liabilities | Regulatory Assets and Liabilities The operations of PNM and TNMP are regulated by the NMPRC, PUCT, and FERC and the provisions of GAAP for rate-regulated enterprises are applied to its regulated operations. Regulatory assets represent probable future recovery of previously incurred costs that will be collected from customers through the ratemaking process.

The Company does not receive or pay a rate of return on the following regulatory assets and regulatory liabilities (and their remaining amortization periods): coal mine reclamation costs (through 2020); deferred income taxes (over the remaining life of the taxable item, up to the remaining life of utility plant); pension and OPEB costs (through 2033); and PVNGS ARO (to be determined in a future regulatory proceeding). The Company is permitted, under rate regulation, to accrue and record a regulatory liability for the estimated cost of removal and salvage associated with certain of its assets through depreciation expense. Under GAAP, actuarial losses and prior service costs for pension plans are required to be recorded in AOCI; however, to the extent authorized for recovery through the regulatory process these amounts are recorded as regulatory assets or liabilities. Based on prior regulatory approvals, the amortization of these amounts will be included in the Company’s rates. Based on a current evaluation of the various factors and conditions that are expected to impact future cost recovery, the Company believes that future recovery of its regulatory assets is probable. |

Construction Program and Jointly-Owned Electric Generating Plants [Abstract] | |
Construction Program and Jointly-Owned Electric Generating Plants | Construction Program and Jointly-Owned Electric Generating Plants PNM is a participant in several jointly-owned power plant projects. The primary operating or participation agreements for the joint projects expire in July 2022 for SJGS, July 2041 for Four Corners, December 2046 for Luna, and November 2047 for PVNGS. PNM’s expenditures for additions to utility plant were $341.8 million in 2019 , including expenditures on jointly-owned projects. TNMP does not participate in the ownership or operation of any generating plants, but incurred expenditures for additions to utility plant of $254.0 million during 2019 . On a consolidated basis, PNMR’s expenditures for additions to utility plant were $616.3 million in 2019 . Joint Projects Under the agreements for the jointly-owned projects, PNM has an undivided interest in each asset and liability of the project and records its pro-rata share of each item in the corresponding asset and liability account on PNM’s Consolidated Balance Sheets. Likewise, PNM records its pro-rata share of each item of operating and maintenance expenses for its jointly-owned plants within the corresponding operating expense account in its Consolidated Statements of Earnings. PNM is responsible for financing its share of the capital and operating costs of the joint projects. At December 31, 2019 , PNM’s interests and investments in jointly-owned generating facilities are: Station (Fuel Type) Plant in Service Accumulated Depreciation (1) Construction Work in Progress Composite Interest (In thousands) SJGS (Coal) $ 779,236 $ (435,312 ) $ 486 66.35 % PVNGS (Nuclear) (2) $ 819,613 $ (369,431 ) $ 31,275 10.20 % Four Corners Units 4 and 5 (Coal) $ 283,939 $ (100,137 ) $ 10,794 13.00 % Luna (Gas) $ 78,258 $ (30,255 ) $ — 33.33 % (1) Includes cost of removal. (2) Includes interest in PVNGS Unit 3 , interest in common facilities for all PVNGS units, and owned interests in PVNGS Units 1 and 2 , including improvements. San Juan Generating Station PNM operates and jointly owns SJGS. Effective January 1, 2018, SJGS Unit 1 is owned 50% by PNM and 50% by Tucson and SJGS Unit 4 is owned 77.297% by PNM, including a 12.8% interest held as merchant plant, 8.475% by Farmington, 7.2% by Los Alamos, and 7.028% by UAMPS. See Notes 16 and 17 for additional information about SJGS, including the shutdown of SJGS Units 2 and 3 in December 2017 and the restructuring of SJGS ownership as well as information on PNM’s SJGS Abandonment Application. Palo Verde Nuclear Generating Station PNM is a participant in the three units of PVNGS with APS (the operating agent), SRP, EPE, SCE, SCPPA, and The Department of Water and Power of the City of Los Angeles. PNM has a 10.2% undivided interest in PVNGS, with portions of its interests in Units 1 and 2 held under leases. See Note 8 for additional information concerning the PVNGS leases, including PNM’s purchase of the assets underlying certain of the leases in January 2016, PNM’s option to purchase or return certain lease interests that have been extended through 2023 and 2024, and Note 17 for the outcome of PNM’s appeal to the NM Supreme Court regarding the NMPRC’s treatment of those purchases and lease extensions in the NM 2015 Rate Case. Operation of each of the three PVNGS units requires an operating license from the NRC. The NRC issued full power operating licenses for Unit 1 in June 1985, Unit 2 in April 1986, and Unit 3 in November 1987. The full power operating licenses were originally for a period of 40 years and authorize APS, as operating agent for PVNGS, to operate the three PVNGS units. In April 2011, the NRC approved extensions in the operating licenses for the plants for 20 years through June 2045 for Unit 1, April 2046 for Unit 2, and November 2047 for Unit 3. Four Corners Power Plant PNM is a participant in two units of Four Corners with APS (the operating agent), an affiliate of APS, SRP, and Tucson. PNM has a 13.0% undivided interest in Units 4 and 5 of Four Corners. The Four Corners plant site is located on land within the Navajo Nation and is subject to an easement from the federal government. APS, on behalf of the Four Corners participants, negotiated amendments to an existing agreement with the Navajo Nation, which extends the owners’ right to operate the plant on the site to July 2041. See Note 16 for additional information about Four Corners. The NMPRC indicated in the NM 2016 Rate Case that it will review the prudency of PNM’s decision to continue its participation in Four Corners in PNM’s next general rate case filing. See Note 17. Luna Energy Facility Luna is a combined-cycle power plant near Deming, New Mexico. Luna is owned equally by PNM, Tucson, and Samchully Power & Utilities 1, LLC. The operation and maintenance of the facility has been contracted to North American Energy Services. Construction Program The Company anticipates making substantial capital expenditures for the construction and acquisition of utility plant and other property and equipment. An unaudited summary of the budgeted construction expenditures, including expenditures for jointly-owned projects, and nuclear fuel, is as follows: 2020 2021 2022 2023 2024 Total (In millions) PNM $ 447.5 $ 701.4 $ 331.6 $ 398.0 $ 280.4 $ 2,158.9 TNMP 337.2 270.0 342.0 348.0 245.0 1,542.2 Corporate and Other 27.0 21.0 21.0 25.0 21.0 115.0 Total PNMR $ 811.7 $ 992.4 $ 694.6 $ 771.0 $ 546.4 $ 3,816.1 The construction expenditure estimates are under continuing review and subject to ongoing adjustment, as well as to Board review and approval. The above construction expenditures include $297.6 million of replacement power in anticipation of the SJGS abandonment and approximately $376.8 million |

Asset Retirement Obligation Disclosure [Abstract] | |
Asset Retirement Obligations | Asset Retirement Obligations AROs are recorded based on studies to estimate the amount and timing of future ARO expenditures and reflect underlying assumptions, such as discount rates, estimates of the future costs for decommissioning, and the timing of the removal activities to be performed. Approximately 76% of PNM’s total ARO liabilities are related to nuclear decommissioning of PVNGS. PNM is responsible for all decommissioning obligations related to its entire interest in PVNGS, including portions under lease both during and after termination of the leases. Studies of the decommissioning costs of PVNGS, SJGS, Four Corners, and other facilities are performed periodically and revisions to the ARO liabilities are recorded. Changes in the assumptions underlying the calculations may also require revisions to the estimated AROs when identified. A reconciliation of the ARO liabilities is as follows: PNMR PNM TNMP (In thousands) Liability at December 31, 2016 $ 127,519 $ 126,601 $ 754 Liabilities incurred (1) 1,854 1,853 — Liabilities settled (968 ) (944 ) (24 ) Accretion expense 10,680 10,603 63 Revisions to estimated cash flows 7,594 7,594 — Liability at December 31, 2017 146,679 145,707 793 Liabilities incurred — — — Liabilities settled (192 ) — — Accretion expense 11,482 11,402 67 Revisions to estimated cash flows 705 705 — Liability at December 31, 2018 158,674 157,814 860 Liabilities incurred — — — Liabilities settled (987 ) (935 ) (52 ) Accretion expense 12,635 12,562 73 Revisions to estimated cash flows (2) 11,640 11,640 — Liability at December 31, 2019 $ 181,962 $ 181,081 $ 881 (1) Represents the obligation related to the additional ownership interest in SJGS Unit 4 that PNM acquired on December 31, 2017 due to the restructuring of the ownership of SJGS.

Commitments and Contingencies Disclosure [Abstract] | |
Commitments and Contingencies | Commitments and Contingencies Overview There are various claims and lawsuits pending against the Company. In addition, the Company is subject to federal, state, and local environmental laws and regulations and periodically participates in the investigation and remediation of various sites. In addition, the Company periodically enters into financial commitments in connection with its business operations. Also, the Company is involved in various legal and regulatory proceedings in the normal course of its business. See Note 17. It is not possible at this time for the Company to determine fully the effect of all litigation and other legal and regulatory proceedings on its financial position, results of operations, or cash flows. With respect to some of the items listed below, the Company has determined that a loss is not probable or that, to the extent probable, cannot be reasonably estimated. In some cases, the Company is not able to predict with any degree of certainty the range of possible loss that could be incurred. The Company assesses legal and regulatory matters based on current information and makes judgments concerning their potential outcome, giving due consideration to the nature of the claim, the amount and nature of any damages sought, and the probability of success. Such judgments are made with the understanding that the outcome of any litigation, investigation, or other legal proceeding is inherently uncertain. In accordance with GAAP, the Company records liabilities for matters where it is probable a loss has been incurred and the amount of loss is reasonably estimable. The actual outcomes of the items listed below could ultimately differ from the judgments made and the differences could be material. The Company cannot make any assurances that the amount of reserves or potential insurance coverage will be sufficient to cover the cash obligations that might be incurred as a result of litigation or regulatory proceedings. Except as otherwise disclosed, the Company does not expect that any known lawsuits, environmental costs, and commitments will have a material effect on its financial condition, results of operations, or cash flows. Commitments and Contingencies Related to the Environment PVNGS Decommissioning Funding The costs of decommissioning a nuclear power plant are substantial. PNM is responsible for all decommissioning obligations related to its entire interest in PVNGS, including portions under lease both during and after termination of the leases. PNM has a program for funding its share of decommissioning costs for PVNGS, including portions held under leases. The nuclear decommissioning funding program is invested in equities and fixed income instruments in qualified and non-qualified trusts. PNM funded $1.3 million , $1.3 million , and $2.0 million for the years ended December 31, 2019, 2018, and 2017 into the qualified and non-qualified trust funds. The market value of the trusts at December 31, 2019 and 2018 was $336.0 million and $287.1 million . See Note 17 for additional discussion of the NM Supreme Court’s decisions in PNM’s appeal of the NMPRC’s decisions in the NM 2015 Rate Case. Nuclear Spent Fuel and Waste Disposal Nuclear power plant operators are required to enter into spent fuel disposal contracts with the DOE that require the DOE to accept and dispose of all spent nuclear fuel and other high-level radioactive wastes generated by domestic power reactors. Although the Nuclear Waste Policy Act required the DOE to develop a permanent repository for the storage and disposal of spent nuclear fuel by 1998, the DOE announced that it would not be able to open the repository by 1998 and sought to excuse its performance of these requirements. In November 1997, the DC Circuit issued a decision preventing the DOE from excusing its own delay but refused to order the DOE to begin accepting spent nuclear fuel. Based on this decision and the DOE’s delay, a number of utilities, including APS (on behalf of itself and the other PVNGS owners, including PNM), filed damages actions against the DOE in the Court of Federal Claims. The lawsuits filed by APS alleged that damages were incurred due to DOE’s continuing failure to remove spent nuclear fuel and high-level waste from PVNGS. In August 2014, APS and the DOE entered into a settlement agreement that establishes a process for the payment of claims for costs incurred through December 31, 2019. Under the settlement agreement, APS must submit claims annually for payment of allowable costs. PNM records estimated claims on a quarterly basis. The benefit from the claims is passed through to customers under the FPPAC to the extent applicable to NMPRC regulated operations. PNM estimates that it will incur approximately $57.7 million (in 2016 dollars) for its share of the costs related to the on-site interim storage of spent nuclear fuel at PVNGS during the term of the operating licenses. PNM accrues these costs as a component of fuel expense as the nuclear fuel is consumed. At December 31, 2019 and 2018 , PNM had a liability for interim storage costs of $12.7 million and $12.4 million , which is included in other deferred credits. PVNGS has sufficient capacity at its on-site Independent Spent Fuel Storage Installation (“ISFSI”) to store all of the nuclear fuel that will be irradiated during the initial operating license period, which ends in December 2027. Additionally, PVNGS has sufficient capacity at its on-site ISFSI to store a portion of the fuel that will be irradiated during the period of extended operation, which ends in November 2047. If uncertainties regarding the U.S. government’s obligation to accept and store spent fuel are not favorably resolved, APS will evaluate alternative storage solutions that may obviate the need to expand the ISFSI to accommodate all of the fuel that will be irradiated during the period of extended operation. The Energy Transition Act On March 22, 2019, the Governor signed into New Mexico state law Senate Bill 489, known as the Energy Transition Act (“ETA”). The ETA became effective as of June 14, 2019 and sets a statewide standard that requires investor-owned electric utilities to have specified percentages of their electric-generating portfolios be from renewable and zero-carbon generating resources. Prior to the enactment of the ETA, the REA established a mandatory RPS requiring utilities to acquire a renewable energy portfolio equal to 10% of retail electric sales by 2011, 15% by 2015, and 20% by 2020. The ETA amends the REA and requires utilities operating in New Mexico to have renewable portfolios equal to 20% by 2020, 40% by 2025, 50% by 2030, 80% by 2040, and 100% zero-carbon energy by 2045. The ETA also amends sections of the REA to allow for the recovery of undepreciated investments and decommissioning costs related to qualifying EGUs that the NMPRC has required be removed from retail jurisdictional rates, provided replacement resources to be included in retail rates have lower or zero-carbon emissions. The ETA requires the NMPRC to review and approve utilities’ annual renewable portfolio plans to ensure compliance with the RPS. The ETA also directs the New Mexico Environmental Improvement Board to adopt standards of performance that limit CO 2 emissions to no more than 1,100 lbs. per MWh beginning January 1, 2023 for new or existing coal-fired EGUs with original installed capacities exceeding 300 MW. The ETA provides for a transition from fossil-fuel generation resources to renewable and other carbon-free resources through certain provisions relating to the abandonment of coal-fired generating facilities. These provisions include the use of “energy transition bonds,” which are designed to be highly rated bonds that can be issued to finance certain costs of abandoning coal-fired facilities that are retired prior to January 1, 2023 for facilities operated by a “qualifying utility,” or prior to January 1, 2032 for facilities that are not operated by the qualifying utility. The amount of energy transition bonds that can be issued to recover abandonment costs is limited to the lesser of $375.0 million or 150% of the undepreciated investment of the facility as of the abandonment date. Proceeds provided by energy transition bonds must be used only for purposes related to providing utility service to customers and to pay “financing costs” (as defined by the ETA). These costs may include plant decommissioning and coal mine reclamation costs provided those costs have not previously been recovered from customers or disallowed by the NMPRC or by a court order. See Note 17 for a discussion of the NM Supreme Court’s decision to affirm the NMPRC’s disallowance of certain costs, including the cost of BDT at SJGS, in PNM’s NM 2015 Rate Case. Proceeds from energy transition bonds may also be used to fund severances for employees of the retired facility and related coal mine and to promote economic development, education and job training in areas impacted by the retirement of the coal-fired facilities. Energy transition bonds must be issued under a NMPRC approved financing order, are secured by “energy transition property,” are non-recourse to the issuing utility, and must be repaid by a non-bypassable charge paid by all customers of the issuing utility. These customer charges are subject to an adjustment mechanism designed to provide for timely and complete payment of principal and interest due under the energy transition bonds. The ETA also provides that utilities must obtain NMPRC approval of competitively procured replacement resources that shall be evaluated based on their cost, economic development opportunity, ability to provide jobs with comparable pay and benefits to those lost upon retirement of the facility, and that do not exceed emissions thresholds specified in the ETA. In determining whether to approve replacement resources, the NMPRC must give preference to resources with the least environmental impacts, those with higher ratios of capital costs to fuel costs, and those located in the school district of the abandoned facility. The ETA also provides for the procurement of energy storage facilities and gives utilities discretion to maintain, control, and operate these systems to ensure reliable and efficient service. PNM expects the ETA will have a significant impact on PNM’s future generation portfolio, including PNM’s planned retirement of SJGS in 2022. See additional discussion in Note 17 of PNM’s SJGS Abandonment Application. PNM cannot predict the full impact of the ETA or the outcome of its pending and potential future generating resource abandonment and replacement resource filings with the NMPRC. The Clean Air Act Regional Haze In 1999, EPA developed a regional haze program and regional haze rules under the CAA. The rule directs each of the 50 states to address regional haze. Pursuant to the CAA, states have the primary role to regulate visibility requirements by promulgating SIPs. States are required to establish goals for improving visibility in national parks and wilderness areas (also known as Class I areas) and to develop long-term strategies for reducing emissions of air pollutants that cause visibility impairment in their own states and for preventing degradation in other states. States must establish a series of interim goals to ensure continued progress by adopting a new SIP every ten years. In the first SIP planning period, states were required to conduct BART determinations for certain covered facilities, including utility boilers, built between 1962 and 1977 that have the potential to emit more than 250 tons per year of visibility impairing pollution. If it was demonstrated that the emissions from these sources caused or contributed to visibility impairment in any Class I area, then BART must have been installed by the beginning of 2018. For all future SIP planning periods, states must evaluate whether additional emissions reduction measures may be needed to continue making reasonable progress toward natural visibility conditions. On January 10, 2017, EPA published in the Federal Register revisions to the regional haze rule. EPA also provided a companion draft guidance document for public comment. The new rule delayed the due date for the next cycle of SIPs from 2019 to 2021, altered the planning process that states must employ in determining whether to impose “reasonable progress” emission reduction measures, and gave new authority to federal land managers to seek additional emission reduction measures outside of the states’ planning process. Finally, the rule made several procedural changes to the regional haze program, including changes to the schedule and process for states to file 5 -year progress reports. EPA’s new rule was challenged by numerous parties. On January 19, 2018, EPA filed a motion to hold the case in abeyance in light of several letters issued by EPA on January 17, 2018 to grant various petitions for reconsideration of the 2017 rule revisions. EPA’s decision to revisit the 2017 rule is not a determination on the merits of the issues raised in the petitions. On December 20, 2018, EPA released a new guidance document on tracking visibility progress for the second planning period. EPA is allowing states discretion to develop SIPs that may differ from EPA’s guidance as long as they are consistent with the CAA and other applicable regulations. On August 20, 2019, EPA finalized the draft guidance that was released in 2017 as a companion to the regional haze rule revisions. The final guidance differs from the draft in several ways. For example, the final guidance recognizes that sources already subject to BART may not need to be re-evaluated under the full four-factor analysis whereas the draft guidance encouraged states to evaluate all sources regardless of whether they were previously subject to BART. In addition, the final guidance recognizes that states may consider both visibility benefits and the cost of different control options when applying the four-factor analysis whereas the draft guidance recommended states require any control measures identified to be reasonable after considering the four-factor analysis alone. SIPs for the second compliance period are due in July 2021. NMED is currently preparing its SIP for the second compliance period and has notified PNM that it will not require a regional haze four-factor analysis for SJGS provided PNM is still planning to retire its share of SJGS in 2022. PNM is continuing to evaluate the potential impacts of these matters. SJGS BART Compliance – SJGS is a source that is subject to the statutory obligations of the CAA to reduce visibility impacts. PNM, as the operating agent for SJGS, engaged in discussions with NMED and EPA which resulted in a non-binding agreement that included the retirement of SJGS Units 2 and 3 by the end of 2017 and the installation of SNCRs on Units 1 and 4 (the Revised State Implementation Plan or “RSIP”), which was approved by the EPA. In addition to the SNCR equipment required by the RSIP, the NSR permit, which was required to be obtained in order to install the SNCRs, specified that SJGS Units 1 and 4 be converted to balanced draft technology (“BDT”). Installation of SNCRs on Unit 1 and BDT equipment on both Units 1 and 4 was completed in 2015 and installation of SNCRs on Unit 4 was completed in January 2016, which dates were within the time frame contained in the RSIP. PNM’s share of the total costs for SNCRs and BDT equipment was $77.7 million . See Note 17 for information concerning the NMPRC’s treatment of BDT in PNM’s NM 2015 Rate Case, parties’ appeals of that order, and the NM Supreme Court’s May 2019 decision in the appeals. After extensive settlement negotiations and public hearings, in December 2015, the NMPRC issued an order adopting a settlement agreement between several parties. As provided in that order: • PNM would retire SJGS Units 2 and 3 (PNM’s ownership interest was 418 MW) by December 31, 2017 and recover, over 20 years, 50% of their undepreciated net book value at that date and earn a regulated return on those costs at PNM’s WACC • PNM was granted a CCN to acquire an additional 132 MW in SJGS Unit 4 with an initial book value of zero , plus the costs of SNCR and other capital additions as a jurisdictional resource to serve PNM’s New Mexico retail customers, and to acquire 65 MW of SJGS Unit 4 as merchant plant effective January 1, 2018; PNM is prohibited from seeking recovery of any undepreciated investment in the 132 MW interest in the event SJGS Unit 4 is abandoned and PNM and PNMR commit that no further coal-fired merchant plant will be acquired at any time by PNM, PNMR, or any PNM affiliate. See additional discussion below regarding these interests under PNM’s December 2018 Compliance Filing • PNM was granted a CCN for 134 MW of PVNGS Unit 3 with an initial rate base value equal to the book value as of December 31, 2017, including transmission assets associated with PVNGS Unit 3 as a jurisdictional resource to serve PNM’s New Mexico retail customers beginning January 1, 2018 • Beginning January 1, 2020, for every MWh produced by 197 MW of coal-fired generation from PNM’s ownership share of SJGS, PNM will acquire and retire one MWh of RECs or allowances that include a zero-CO 2 emission attribute compliant with EPA’s Clean Power Plan; this REC retirement is in addition to what is required to meet the RPS; the cost of these RECs are to be capped at $7.0 million per year and will be recovered in rates; PNM should purchase EPA-compliant RECs from New Mexico renewable generation unless those RECs are more costly • PNM would accelerate recovery of SNCR costs on SJGS Units 1 and 4 so that the costs are fully recovered by July 1, 2022 • PNM was required to make a filing with the NMPRC no later than December 31, 2018 to determine the extent to which SJGS should continue serving PNM’s retail customers’ needs after June 30, 2022. See additional discussion of this matter below under PNM’s December 2018 Compliance Filing SJGS Units 2 and 3 were shut down in December 2017. At shutdown, the carrying value for PNM’s ownership share of SJGS Units 2 and 3 was comprised of plant in service of $439.4 million and accumulated depreciation and amortization (including cost of removal) of $188.3 million for a net book value of $251.1 million . As of December 31, 2017, these amounts were written off and offset by losses recorded upon the NMPRC’s December 2015 approval and subsequent adjustments totaling $128.6 million . PNM also recorded a regulatory asset of $125.5 million for the 50% of the undepreciated book value that is being recovered from ratepayers pursuant to the NMPRC’s December 2015 order described above. This resulted in the reversal of previously recorded losses of $3.0 million being recorded at December 31, 2017. In addition, PNM recognized a reversal of $1.0 million of previously recorded losses for other unrecoverable costs. These reversals, which total $4.0 million , are included in regulatory disallowances and restructuring costs on the Consolidated Statements of Earnings. All appeals of this matter have been resolved and the matter is now concluded. December 2018 Compliance Filing – As discussed above, in December 2015 PNM received NMPRC approval for a plan to comply with EPA’s regional haze rule at SJGS. Among other things, the NMPRC’s December 2015 order required that, no later than December 31, 2018, PNM make a filing with the NMRPC to determine the extent to which SJGS should continue serving PNM’s customers’ needs after June 30, 2022 (the “December 2018 Compliance Filing”). The December 2018 Compliance Filing was required to be made before PNM entered into a binding commitment for post-2022 coal supply but after PNM received firm pricing and other terms for the supply of coal at SJGS, unless PNM did not intend to pursue an agreement for post-2022 coal supply at SJGS. The NMPRC’s December 2015 order also indicated that, if SJGS Unit 4 is abandoned with undepreciated investment on PNM’s books, PNM is prohibited from recovering the undepreciated investment of its 132 MW interest and required that PNM’s 65 MW interest in SJGS Unit 4 be treated as excluded merchant plant. PNM is currently depreciating virtually all of its investments in SJGS through 2053, which reflects the period of time over which the NMPRC has authorized PNM to recover its investment in SJGS from New Mexico retail customers. PNM submitted the December 2018 Compliance Filing to the NMPRC on December 31, 2018 indicating that, consistent with the conclusions reached in PNM’s 2017 IRP, PNM’s customers would benefit from the retirement of PNM’s share of SJGS after the current SJGS CSA expires in mid-2022. The December 2018 Compliance Filing also indicated that, pursuant to the terms of the agreements governing SJGS, all of the SJGS owners except for Farmington provided written notice that they do not intend to extend the SJGS operating agreements beyond their June 30, 2022 expiration dates, and that PNM has provided written notice to the San Juan mine operator that PNM does not intend to extend the SJGS CSA beyond June 30, 2022. On January 30, 2019, the NMPRC issued an order initiating a proceeding and requiring PNM to submit an application for the abandonment of PNM’s share of SJGS by March 1, 2019. PNM filed a motion requesting the NMPRC vacate the January 30, 2019 order, which was deemed denied. On February 27, 2019, PNM filed a petition with the NM Supreme Court stating that the requirements of the January 30, 2019 order exceed the NMPRC’s authority by, among other things, mandating PNM to make a filing that is legally voluntary, and that the order is contrary to NMPRC precedent which requires abandonment applications to also include identified replacement resources and other information that would not be available to PNM by March 1, 2019. On March 1, 2019, the NM Supreme Court granted a temporary stay of the NMPRC’s order. Various parties intervened in the petition. On June 26, 2019, and after the effective date of the ETA, the NM Supreme Court lifted the stay and denied PNM’s petition without discussion. On July 1, 2019, PNM filed its SJGS Abandonment Application. See Note 17. GAAP requires that long-lived assets be tested for impairment when events or changes in circumstances indicate that their carrying value may not be recoverable. As of December 31, 2018, PNM evaluated the events surrounding its future participation in SJGS and determined that it is more likely than not that PNM’s share of SJGS will be retired in 2022. As a result, PNM performed an impairment analysis that assumed SJGS would not continue to operate through 2053, as previously approved by the NMPRC. PNM’s impairment analysis indicated that, pursuant to the NMPRC’s December 2015 order, PNM’s undepreciated 132 MW interest in SJGS Unit 4 at June 30, 2022 will not be recovered from customers; that the estimated future cash flows expected to result from the operation of SJGS Unit 4 through June 30, 2022 are not sufficient to provide for recovery of PNM’s 65 MW merchant interest in the facility; and that it is unlikely PNM will be able to sell or transfer its interests in SJGS to third parties at amounts sufficient to provide for their recovery. As a result, as of December 31, 2018, PNM recorded a pre-tax impairment of its investment in SJGS of approximately $35.0 million , which is reflected as regulatory disallowances and restructuring costs on the Consolidated Statements of Earnings. This amount includes the entire $11.9 million carrying value of PNM’s 65 MW interest in SJGS Unit 4 as of December 31, 2018 and $23.1 million of estimated undepreciated investments in PNM’s 132 MW jurisdictional interest as of June 30, 2022 that will not be recovered from customers. See additional discussion below regarding the increase in PNM’s estimated liability for coal mine reclamation. NEE Complaint – On March 31, 2016, NEE filed a complaint with the NMPRC alleging that PNM failed to comply with its discovery obligation in the case authorizing the shutdown of SJGS Units 2 and 3 and requesting the NMPRC investigate whether financing provided by NM Capital to the former owner of SJCC (the “Westmoreland Loan”) could adversely affect PNM’s ability to provide electric service to its retail customers. On January 31, 2018, NEE filed a motion asking the NMPRC to investigate whether PNM’s relationship with the former owner of SJCC could be harmful to PNM’s customers. On May 23, 2018, PNM filed its response to the NMPRC staff’s comments noting that the Westmoreland Loan was paid in full on May 22, 2018. On October 11, 2018, PNM notified the NMPRC that the former owner of SJCC, Westmoreland, had filed voluntary petitions for relief under Chapter 11 of the U.S. Bankruptcy Code. As discussed in Note 10, on March 15, 2019, Westmoreland announced that it had emerged from Chapter 11 bankruptcy as a privately held company owned and operated by a group of its former creditors. Under the reorganization, all the assets of SJCC were sold to WSJ LLC. As successor entity to SJCC, WSJ LLC assumed all rights and obligations of Westmoreland including obligations to PNM under the SJGS CSA. The NMPRC has taken no further action on NEE’s complaints. PNM is not able to predict the potential outcome of this matter but does not anticipate the NMPRC will take any further action. SJGS Ownership Restructuring Matters – Prior to December 31, 2017, SJGS was jointly owned by PNM and eight other entities, including three participants that operate in the State of California. Furthermore, each participant did not have the same ownership interest in each unit. The SJPPA that governs the operation of SJGS expires on July 1, 2022. In connection with requirements to install SNCR and BDT equipment at SJGS, certain participants indicated their intent to exit ownership in the plant. As a result, the SJGS participants negotiated a restructuring of the ownership in SJGS and addressed the obligations of the exiting participants for plant decommissioning, mine reclamation, environmental matters, and certain future operating costs, among other items. Prior to the restructuring, the exiting participants owned 50.0% of SJGS Unit 3 and 38.8% of SJGS Unit 4, but none of SJGS Units 1 and 2, and PNM owned 50.0% of SJGS Units 1, 2, and 3 and 38.5% of SJGS Unit 4. Following mediated negotiations, the SJGS participants executed the San Juan Project Restructuring Agreement (“SJGS RA”). The SJGS RA provides the essential terms of restructured ownership and addresses other related matters, including that the exiting participants remain obligated for their proportionate shares of environmental, mine reclamation, and certain other legacy liabilities that are attributable to activities that occurred prior to their exit. Under the SJGS RA, PNM would acquire 132 MW and PNMR Development would acquire 65 MW of the capacity in SJGS Unit 4 from the exiting owners on the exit date for no initial cost other than funding certain capital improvements. Consistent with the NMPRC order, PNM acquired the rights and obligations related to the 65 MW from PNMR Development effective on December 31, 2017 in order to facilitate dispatch of power from that capacity. SJGS Units 2 and 3 were shut down in December 2017 and the restructuring of SJGS ownership under the SJGS RA occurred on December 31, 2017, including PNM’s acquisition of the additional 132 MW and 65 MW ownership interests in SJGS Unit 4 as set forth above. As ordered by the NMPRC, PNM treats the 65 MW interest as merchant utility plant that is excluded from retail rates. PNM has agreements to sell the power from 36 MW of that capacity to a third party at a fixed price for the period January 1, 2018 through June 30, 2022. See Note 9. Beginning in 2018, SJGS is jointly owned by five entities. Including the 65 MW considered to be merchant plant, PNM’s ownership share is 77.3% in SJGS Unit 4 and an aggregate of 66.3% in SJGS Units 1 and 4. See Note 17 for additional discussion of PNM’s July 1, 2019 SJGS Abandonment Application. Four Corners On August 6, 2012, EPA issued its Four Corners FIP with a final BART determination for Four Corners. The rule included two compliance alternatives. On December 30, 2013, APS notified EPA that the Four Corners participants selected the alternative that required APS to permanently close Units 1, 2, and 3 by January 1, 2014 and install SCR post-combustion NOx control technology on each of Units 4 and 5 by July 31, 2018. Installation of SCRs on Four Corners Unit 5 was completed in March 2018 and the installation on Unit 4 was completed in June 2018. PNM owns a 13% interest in Units 4 and 5, but had no ownership interest in Units 1, 2, and 3, which were shut down by APS on December 30, 2013. For particulate matter emissions, EPA is requiring Units 4 and 5 to meet an emission limit of 0.015 lbs./MMBTU and the plant to meet a 20% opacity limit, both of which are achievable through operation of the existing baghouses. Although unrelated to BART, the final BART rule also imposes a 20% opacity limitation on certain fugitive dust emissions from Four Corners’ coal and material handling operations. PNM share of costs for post-combustion controls at Four Corners Units 4 and 5 through December 31, 2018 was $88.7 million , including PNM’s AFUDC. See Note 17 for information on the NMPRC’s treatment of these costs in PNM’s NM 2016 Rate Case. The Four Corners plant site is located on land within the Navajo Nation. APS, on behalf of the Four Corners participants, negotiated amendments to the existing agreement with the Navajo Nation, which extends the owners’ right to operate the plant on the site to July 2041. The DOI issued a Record of Decision on July 17, 2015 approving the 25 -year extension for Four Corners, authorizes continued mining operations to supply the remaining units at Four Corners, renews transmission line and access road rights-of-way on the Navajo and Hopi Reservations, and accepts the proposed mining plan for the Navajo Mine. The Four Corners participants’ obligations to comply with EPA’s final BART determinations, coupled with the financial impact of climate change regulation or legislation, other environmental regulations, and other business or regulatory considerations, could jeopardize the economic viability of Four Corners or the ability of individual participants to continue their participation in Four Corners. Four Corners Federal Agency Lawsuit – On April 20, 2016, several environmental groups filed a lawsuit against OSM and other federal agencies in the U.S. District Court for the District of Arizona in connection with their issuance of the approvals that extended the life of Four Corners and the adjacent mine. The lawsuit alleges that these federal agencies violated both the ESA and NEPA in providing the federal approvals necessary to extend operations at Four Corners and the adjacent mine past July 6, 2016. The court granted an APS motion to intervene in the litigation. On September 15, 2016, NTEC, the current owner of the mine providing coal to Four Corners, filed a motion to intervene for the limited purpose of seeking dismissal of the lawsuit based on NTEC’s tribal sovereign immunity. On September 11, 2017, the court granted NTEC’s motion and dismissed the case with prejudice, terminating the proceedings. The environmental group plaintiffs filed a Notice of Appeal of the dismissal in the U.S. Court of Appeals for the Ninth Circuit on November 9, 2017, and the court granted their subsequent motion to expedite the appeal. Oral arguments for the appeal were held on March 7, 2019. On July 29, 2019, the Ninth Circuit issued a decision affirming the District Court’s dismissal of the case. In September 2019, the environmental groups filed a motion for reconsideration, which was denied in December 2019. PNM cannot predict whether parties will seek further review of this matter by means of petitioning the U.S. Supreme Court or the outcome of potential future litigation. Carbon Dioxide Emissions On August 3, 2015, EPA established standards to limit CO 2 emissions from power plants. EPA took three separate but related actions in which it: (1) established the Carbon Pollution Standards for new, modified, and reconstructed power plants; (2) established the Clean Power Plan to set standards for carbon emission reductions from existing power plants; and (3) released a proposed federal plan associated with the final Clean Power Plan. The Clean Power Plan was published on October 23, 2015. Multiple states, utilities, and trade groups filed petitions for review in the DC Cir |

Regulated Operations [Abstract] | |
Regulatory and Rate Matters | Regulatory and Rate Matters 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 Cases New Mexico 2015 General Rate Case (“NM 2015 Rate Case”) On August 27, 2015, PNM filed an application with the NMPRC for a general increase in retail electric rates. The application proposed a revenue increase of $123.5 million , including base non-fuel revenues of $121.7 million , and proposed that new rates become effective beginning in July 2016. Subsequent to public hearings, the NMPRC ordered PNM to file additional testimony regarding PNM’s interests in PVNGS, including the 64.1 MW of PVNGS Unit 2 that PNM repurchased in January 2016 pursuant to the terms of the initial sales-leaseback transactions. In August 2016, the Hearing Examiner in the case issued a recommended decision (the “August 2016 RD”). The August 2016 RD, among other things, recommended that the NMPRC find PNM was imprudent in the actions taken to purchase the previously leased 64.1 MW of capacity in PVNGS Unit 2, extending the leases for 114.6 MW of capacity of PVNGS Units 1 and 2, and installing the BDT equipment on SJGS Units 1 and 4. As a result, the August 2016 RD recommended the NMPRC disallow recovery of the entire $163.3 million purchase price for the January 15, 2016 purchases of the assets underlying three leases aggregating 64.1 MW of PVNGS Unit 2, the undepreciated capital improvements made during the period the 64.1 MW of purchased capacity was leased, rent expense aggregating $18.1 million annually for leases aggregating 114.6 MW of capacity that were extended through January 2023 and 2024 (Note 8), and recovery of the costs of converting SJGS Units 1 and 4 to BDT. On September 28, 2016, the NMPRC issued an order that authorized PNM to implement an increase in non-fuel rates of $61.2 million , effective for bills sent to customers after September 30, 2016. The order generally approved the August 2016 RD, but with certain significant modifications. The modifications to the August 2016 RD included: • Inclusion of the January 2016 purchase of the assets underlying three leases of capacity, aggregating 64.1 MW, of PVNGS Unit 2 at an initial rate base value of $83.7 million ; and disallowance of the recovery of the undepreciated costs of capitalized improvements made during the period the 64.1 MW was being leased by PNM, which aggregated $43.8 million when the order was issued • Recovery of annual rent expenses associated with the 114.6 MW of capacity under the extended leases • Disallowance of the recovery of any future contributions for PVNGS decommissioning costs related to the 64.1 MW of capacity purchased in January 2016 and the 114.6 MW of capacity under the extended leases On September 30, 2016, PNM filed a notice of appeal with the NM Supreme Court regarding the order in the NM 2015 Rate Case. Specifically, PNM appealed the NMPRC’s determination that PNM was imprudent in certain matters in the case, including the NMPRC’s disallowance of the full purchase price of the 64.1 MW of capacity in PVNGS Unit 2, the undepreciated costs of capitalized improvements made during the period the 64.1 MW of capacity was leased by PNM, the cost of converting SJGS Units 1 and 4 to BDT, and future contributions for PVNGS decommissioning attributable to the 64.1 MW of purchased capacity and the 114.6 MW of capacity under the extended leases. NEE, NM AREA, and ABCWUA filed notices of cross-appeal to PNM’s appeal. The issues appealed by the various cross-appellants included, among other things, the NMPRC allowing PNM to recover any of the costs of the lease extensions for the 114.6 MW of PVNGS Units 1 and 2 and the purchase price for the 64.1 MW in PVNGS Unit 2, the costs incurred under the Four Corners CSA, and the inclusion of the “prepaid pension asset” in rate base. During the pendency of the appeal, PNM evaluated the consequences of the order in the NM 2015 Rate Case and the related appeals to the NM Supreme Court as required under GAAP. These evaluations indicated that it was reasonably possible that PNM would be successful on the issues it was appealing but would not be provided capital costs recovery until the NMPRC acted on a decision of the NM Supreme Court. PNM also evaluated the accounting consequences of the issues being appealed by the cross-appellants and concluded that the issues raised in the cross-appeals did not have substantial merit. In accordance with GAAP, PNM periodically updated its estimate of the amount of time necessary for the NM Supreme Court to render a decision and for the NMPRC to take action on any remanded issues. As a result of those evaluations, through December 31, 2018, PNM recorded accumulated pre-tax impairments of its capital investments subject to the appeal in the amount of $18.4 million , of which $4.0 million was recorded during the year ended December 31, 2018, and $3.1 million was recorded during the year ended December 31, 2017. On May 16, 2019, the NM Supreme Court issued its decision on the matters that had been appealed in the NM 2015 Rate Case. The NM Supreme Court rejected the matters appealed by the cross-appellants and affirmed the NMPRC’s disallowance of a portion of the purchase price of the 64.1 MW of capacity in PVNGS Unit 2; the undepreciated costs of capital improvements made during the time the 64.1 MW capacity was leased by PNM; and the costs to install BDT at SJGS Units 1 and 4. The NM Supreme Court’s decision also ruled that the NMPRC’s decision to permanently disallow recovery of future decommissioning costs related to the 64.1 MW of PVNGS Unit 2 and the 114.6 MW of PVNGS Units 1 and 2 deprived PNM of its rights to due process of law and remanded the case to the NMPRC for further proceedings consistent with the court’s findings. On July 17, 2019, the NMPRC heard oral argument from parties in the case on how to best proceed with the NM Supreme Court’s remand. At oral argument, parties presented various positions ranging from re-litigating the value of PVNGS resources determined by the NMPRC and affirmed by the NM Supreme Court to re-affirming the NMPRC’s final order with a single modification to address recovery of future PVNGS decommissioning costs in a future case. On January 8, 2020, the NMPRC issued its order in response to the NM Supreme Court’s remand. The NMPRC reaffirmed its September 2016 order except for the decision to permanently disallow recovery of certain future decommissioning costs related to PVNGS Units 1 and 2. The NMPRC indicated that PNM’s ability to recover these costs will be addressed in a future proceeding and closed the NM 2015 Rate Case docket. As a result of the NM Supreme Court’s ruling, during the year ended December 31, 2019, PNM recorded pre-tax impairments of $150.6 million , which includes $73.2 million for a portion of the purchase price for 64.1 MW in PVNGS Unit 2, $39.7 million of undepreciated capitalized improvements made during the period the 64.1 MW was being leased by PNM, and $37.7 million for BDT on SJGS Units 1 and 4 and is reflected as regulatory disallowances and restructuring costs in the Consolidated Statements of Earnings. The impairment was offset by tax impacts of $45.7 million , which are reflected as income taxes on the Consolidated Statements of Earnings. New Mexico 2016 General Rate Case (“NM 2016 Rate Case”) On December 7, 2016, PNM filed an application with the NMPRC for a general increase in retail electric rates. PNM did not include any of the costs disallowed in the NM 2015 Rate Case that were at issue in its then pending appeal to the NM Supreme Court. PNM’s original application used a FTY beginning January 1, 2018 and requested an increase in base non-fuel revenues of $99.2 million based on a ROE of 10.125% . The primary drivers of PNM’s revenue deficiency included implementation of modifications to PNM’s resource portfolio, which were approved by the NMPRC in December 2015 as part of the SJGS regional haze compliance plan, infrastructure investments, including environmental upgrades at Four Corners, declines in forecasted energy sales due to successful energy efficiency programs and other economic factors, and updates to FERC/retail jurisdictional allocations. After extensive settlement negotiations and public proceedings, the NMPRC issued a Revised Order Partially Adopting Certification of Stipulation dated January 10, 2018 (the “Revised Order”). The key terms of the Revised Order include: • An increase in base non-fuel revenues totaling $10.3 million , which includes a reduction to reflect the impact of the decrease in the federal corporate income tax rate and updates to PNM’s cost of debt (aggregating an estimated $47.6 million annually) • A ROE of 9.575% • Returning to customers over a three -year period the benefit of the reduction in the New Mexico corporate income tax rate to the extent attributable to PNM’s retail operations (Note 18) • Disallowing PNM’s ability to collect an equity return on certain investments aggregating $148.1 million at Four Corners, but allowing recovery with a debt-only return • An agreement to not implement non-fuel base rate changes, other than changes related to PNM’s rate riders, with an effective date prior to January 1, 2020 • A requirement to consider the prudency of PNM’s decision to continue its participation in Four Corners in PNM’s next general rate case filing In accordance with the settlement agreement and the NMPRC’s final order, PNM implemented 50% of the approved increase for service rendered beginning February 1, 2018 and implemented the rest of the increase for service rendered beginning January 1, 2019. Investigation/Rulemaking Concerning NMPRC Ratemaking Policies On March 22, 2017, the NMPRC issued an order opening an investigation and rulemaking to simplify and increase “the transparency of NMPRC rate cases by reducing the number of issues litigated in rate cases,” and provide a “more level playing field among intervenors and NMPRC staff on the one hand, and the utilities on the other.” The order posed several questions establishing and monitoring utilities’ ROEs, the recoverability of regulatory assets, including rate case costs, and whether parties should have access to software used by utilities to support their positions. To date, no agreement has been reached. PNM is not able to predict the potential outcome of this matter but does not anticipate the NMPRC will take any further action. Renewable Portfolio Standard Prior to the enactment of the ETA, the REA established a mandatory RPS requiring a utility to acquire a renewable energy portfolio equal to 10% of retail electric sales by 2011, 15% by 2015, and 20% by 2020. As discussed in Note 16, the ETA was enacted on June 14, 2019. The ETA amends the REA and requires utilities operating in New Mexico to have renewable portfolios equal to 20% by 2020, 40% by 2025, 50% by 2030, 80% by 2040, and 100% zero-carbon energy by 2045. The ETA also removes 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 RCT for the procurement of renewable resources to prevent excessive costs being added to rates. The ETA sets a RCT of $60 per MWh using an average annual levelized resource cost basis. PNM makes renewable procurements consistent with the NMPRC approved plans. PNM recovers certain renewable procurement costs from customers through a rate rider. See Renewable Energy Rider below. Included in PNM’s approved procurement plans are the following renewable energy resources: • 157 MW of PNM-owned solar-PV facilities, including 50 MW of PNM-owned solar-PV facilities approved by the NMPRC in PNM’s 2018 renewable energy procurement plan that were placed in commercial operation in 2019 • A PPA through 2044 for the output of New Mexico Wind, having a current aggregate capacity of 204 MW, and a PPA through 2035 for the output of Red Mesa Wind, having an aggregate capacity of 102 MW • A PPA through 2042 for the output of the Lightning Dock Geothermal facility with a current capacity of 15 MW • Solar distributed generation, aggregating 127.6 MW at December 31, 2019, owned by customers or third parties from whom PNM purchases any net excess output and RECs • Solar and wind RECs as needed to meet the RPS requirements PNM filed its 2017 renewable energy procurement plan on June 1, 2016. The plan met RPS and diversity requirements for 2017 and 2018 using existing resources and PNM did not propose any significant new procurements. PNM projected that its plan would slightly exceed the RCT in 2017 and would be within the RCT in 2018. PNM requested a variance from the RCT in 2017. A public hearing was held on September 26, 2016. On October 21, 2016, the Hearing Examiner issued a recommended decision recommending that the plan be approved as filed and also found that a variance from the RCT was not required. The NMPRC approved the recommended decision on November 23, 2016. On June 1, 2017, PNM filed its 2018 renewable energy procurement plan. PNM requested approval to procure an additional 80 GWh in 2019 and 105 GWh in 2020 from a re-powering of New Mexico Wind; approval to procure an additional 55 GWh in 2019 and 77 GWh in 2020 from a re-powering of Lightning Dock Geothermal; approval to procure 50 MW of new PNM-owned solar facilities to be constructed beginning in 2018, and continuation of customer REC purchase programs and other purchases of RECs to ensure annual compliance with the RPS. The plan also sought a variance from the “other” diversity category in 2018 due to a revised production forecast of the Lightning Dock Geothermal facility in 2018. A public hearing on the application was held in September 2017. On October 17, 2017, the Hearing Examiner issued a recommended decision that PNM’s 2018 renewable energy procurement plan be approved by the NMPRC, except for the re-powering of Lightning Dock Geothermal and PNM’s request to procure 50 MW of new PNM-owned solar facilities. PNM filed exceptions contesting the Hearing Examiner’s proposals. On November 15, 2017, the NMPRC issued an order approving PNM’s plan and rejecting the Hearing Examiner’s recommendations. On November 29, 2017, NM AREA filed an appeal with the NM Supreme Court objecting to the fuel allocation methodology and requested a partial stay of the NMPRC order, which was denied. NEE subsequently filed a motion to intervene and cross-appeal objecting to the approval of the 50 MW of new PNM-owned solar facilities. On July 5, 2019, the NM Supreme Court approved a motion filed by NM AREA to dismiss its appeal. On August 8, 2019, the NM Supreme Court issued an opinion affirming the NMPRC’s approval of PNM’s 2018 renewable energy procurement plan and denying NEE’s cross appeal. This matter is now concluded. On June 1, 2018, PNM filed its 2019 renewable energy procurement plan. The plan met RPS and diversity requirements for 2019 and 2020 using resources already approved by the NMPRC and did not propose any significant new procurements. PNM projected the plan would be within the RCT in 2019 and will slightly exceed the current RCT in 2020. The NMPRC approved PNM’s 2019 renewable energy procurement plan on November 28, 2018. On June 3, 2019, PNM filed its 2020 renewable energy procurement plan. The plan requests approval of a 20 -year PPA to purchase 140 MW of renewable energy and RECs from the La Joya Wind Facility (“La Joya Wind”), which is expected to be operational by December 31, 2020. PNM intends to utilize the BB2 line to deliver power from the PPA. See additional discussion below under Application for a New 345 -kV Transmission Line . PNM’s 2020 renewable energy procurement plan requests a variance from the RPS for 2020 and proposes the shortfall be met with excess RECs that will be available under the La Joya Wind PPA in 2021. PNM also submitted proposed adjustments to the current FPPAC methodology for non-renewable fuel allocations to reflect the ETA’s removal of certain customer cost caps associated with the RPS and requested that the fuel clause year be reset to correspond to the January 1 reset date under the renewable energy rider. On July 17, 2019, PNM filed a corrected reconciliation of 2019 and estimated 2020 customer bill impacts that demonstrated the effect of removing certain customer caps and exemptions under the requirements of the ETA. The Hearing Examiner issued a response requiring PNM to address why its application should not be dismissed, or alternatively, proposing an extended procedural schedule. PNM’s response proposed the application not be dismissed, that a corrected public notice be issued, and that the procedural schedule be extended by 60 days. On July 30, 2019, the Hearing Examiner issued a revised procedural order that extended the statutory review period through January 29, 2020. On September 17, 2019, the Hearing Examiner issued an order requiring PNM to provide supplemental briefing supporting the applicability of the ETA to PNM’s 2020 renewable energy procurement plan and, in the event the ETA should not apply, support PNM’s position that the NMPRC has the authority to approve PNM’s requested variance. PNM filed its brief on September 24, 2019, supporting the applicability of the ETA and the NMPRC’s authority to grant the requested variance. On October 4, 2019, the Hearing Examiner issued an order requiring PNM to provide RPS calculations using rules and regulations existing before the ETA. PNM filed its rebuttal testimony on October 15, 2019, which included the calculations required by the Hearing Examiner. Public hearings were held on October 24 and 25, 2019. On December 2, 2019, the Hearing Examiner issued a recommended decision in the case recommending approval of PNM’s 2020 renewable energy procurement plan including the 140 MW wind PPA and indicating that the recently enacted ETA could be applied to the case even though PNM’s filing was made prior to the ETA’s effective date. On January 29, 2020, the NMPRC accepted the Hearing Examiners recommended decision and approved PNM’s 2020 renewable energy procurement plan. Renewable Energy Rider The NMPRC has authorized PNM to recover certain renewable procurement costs through a rate rider billed on a per KWh basis. In PNM’s NM 2015 Rate Case, the NMPRC authorized continuation of the renewable rider. PNM recorded revenues from the rider of $52.0 million , $41.4 million , and $45.2 million in 2019, 2018, and 2017. Beginning in 2017, the cost of energy from New Mexico Wind is being recovered through the renewable rider, rather than through the FPPAC, in compliance with the NMPRC’s order in PNM’s NM 2015 Rate Case. The 2019 renewable energy procurement plan became effective on January 1, 2019. In its 2020 renewable energy procurement plan case, which was approved by the NMPRC on January 29, 2020, PNM proposed to collect $58.9 million . 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 did not exceed such limitation in 2018 and does not expect to exceed the limitation in 2019. Energy Efficiency and Load Management Program Costs and Incentives/Disincentives The New Mexico Efficient Use of Energy Act (“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. The EUEA sets an annual program budget equal to 3% of an electric utility’s annual revenue. PNM’s costs to implement approved programs 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, and to establish savings targets for the period 2021 through 2025. On April 15, 2016, PNM filed an application for energy efficiency and load management programs to be offered in 2017. The proposed program portfolio consisted of ten programs with a total budget of $28.0 million . The application also sought approval of an incentive of $2.4 million based on targeted savings of 75 GWh. The actual incentive would be based on actual savings achieved. On January 11, 2017, the NMPRC approved an unopposed stipulation that established a method to ensure that funding of PNM’s energy efficiency program is equal to 3% of retail revenues, with an estimated 2017 energy efficiency funding level of $26.0 million , and approved a sliding scale profit incentive with a base level of 7.1% of program costs, equal to $1.8 million , if PNM achieves a minimum proscribed level of energy savings, increasing to a maximum of 9.0% depending on actual energy savings achieved above the minimum. On April 13, 2018, PNM filed its reconciliation of 2017 program costs and incentives, which indicated the incentive earned in 2017 was $2.3 million . The reconciliation filing and related incentive were accepted on May 23, 2018. On April 14, 2017, PNM filed an application for energy efficiency and load management programs to be offered in 2018. The proposed program portfolio consists of a continuation of the ten programs approved in the 2016 application with a total budget of $25.1 million . The application also sought approval of a sliding scale incentive with a base incentive of $1.9 million if PNM was able to achieve savings of 53 GWh in 2018. As proposed, PNM would have earned an incentive of $2.1 million based on targeted savings of 70 GWh. The actual incentive would be based on actual savings achieved. PNM proposed to continue the same ten programs and a similar incentive mechanism in 2019, with a proposed budget of $28.2 million and a base level incentive of $2.1 million . On July 26, 2017, PNM, NMPRC staff, and other parties filed a stipulation that would resolve all issues in the case if approved by the NMPRC. Under the settlement, all of PNM’s proposed programs would be approved with limited modifications and PNM’s base level incentive would be $1.7 million and could earn an incentive of up to $1.9 million based on savings of 69 GWh in 2018. The settlement also established a base level incentive for PNM of $1.8 million with the opportunity to earn up to $2.7 million in 2019 and required PNM to make a filing in 2019 to address incentives to be earned in 2020. A public hearing was held in September 2017. On November 8, 2017, the Hearing Examiner recommended approval of the stipulation with various modifications, including adoption of a discount rate equal to the tax-adjusted WACC of 9.59% rather than the 7.71% proposed in the stipulation and modifying the program budgets to $23.6 million for 2018 and $24.9 million for 2019. On January 31, 2018, the NMPRC issued an order that largely accepted the certification with certain exceptions concerning the measurement and verification of the approved load management programs. In 2019, PNM submitted the required filing to address incentives to be earned in 2020. PNM’s proposed incentive mechanism is similar to that approved for 2018 and 2019 with minor modifications to reflect input from interested parties. The proposed incentive mechanism includes a base incentive of 7.1% of program costs, or approximately $1.8 million , based on savings of 59 GWh in 2020 with a sliding scale that provides for additional incentive if savings exceed 68 GWh. No hearings were considered necessary and PNM’s 2020 energy efficiency rider reflecting the 2020 incentive became effective beginning December 30, 2019. Energy Efficiency Rulemaking In July 2012, the NMPRC opened an energy efficiency rulemaking docket to potentially address decoupling and incentives. Workshops to develop a proposed rule have been held, but no order proposing a rule has been issued. PNM is unable to predict the outcome of this matter. On January 25, 2017, the NMPRC opened another energy efficiency rulemaking docket to consider whether applications for approval of energy efficiency and load management programs should be filed every two years rather than annually. On June 21, 2017, the NMPRC issued an order that modifies the filing frequency for utility energy efficiency plans to every three years . On June 21, 2017, the NMPRC also issued a new notice of proposed rulemaking to consider possible changes affecting a utility’s ability to modify NMPRC approved funding levels by up to 10% between energy efficiency program applications. This rulemaking is in response to consensus changes proposed by parties in the January 25, 2017 rulemaking. On September 13, 2017, the NMPRC approved the proposed rule. Under the new rule, PNM’s next application for energy efficiency and load management programs will be made in 2020 for programs to be offered beginning in 2021. As discussed below, PNM’s next energy efficiency application will include a proposal to implement an AMI pilot project. Petition for Energy Efficiency Disincentive PNM’s application in the NM 2016 Rate Case had requested a “lost contribution to fixed cost” mechanism to address the disincentives associated with PNM’s energy efficiency programs. In the revised stipulation to that case, PNM agreed to withdraw its proposal for such a mechanism and to address energy efficiency disincentives in a future docket. On March 2, 2018, PNM filed a petition proposing a “lost contribution to fixed cost mechanism” with substantially the same terms as those proposed in the NM 2016 Rate Case application. As discussed above, the ETA amended the EUEA to, among other things, include a decoupling mechanism for disincentives. On May 6, 2019, PNM submitted a request to the NMPRC to dismiss this matter. PNM will propose a mechanism to address disincentives in a future general rate case filing. The NMPRC approved PNM’s request to dismiss the matter on June 12, 2019, concluding this matter. FPPAC Continuation Application NMPRC rules require public utilities to file an application to continue using their FPPAC every four years . On April 23, 2018, PNM filed the required continuation application and requested that its FPPAC be continued without modification. On June 20, 2018, the NMPRC approved PNM’s continuation application. 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 four years of that period. 2014 IRP PNM filed its 2014 IRP on July 1, 2014. On July 31, 2014, several parties requested the NMPRC to not accept the 2014 IRP as compliant with NMPRC rules because to do so could affect the then pending proceeding on PNM’s application to abandon SJGS Units 2 and 3 and for CCNs for certain replacement resources and because they asserted that the 2014 IRP did not conform to the NMPRC’s IRP rule. The NMPRC issued an order in August 2014 that docketed a case to determine whether the 2014 IRP complied with applicable NMPRC rules. The order also held the case in abeyance pending the issuance of final, non-appealable orders in PNM’s 2015 renewable energy procurement plan case and its application to retire SJGS Units 2 and 3. On May 4, 2016, the NMPRC issued a Notice of Proposed Dismissal, stating that the docket would be closed with prejudice within thirty days unless good cause was shown why the docket should remain open. On May 31, 2016, NEE filed a request to hold the protests filed against PNM’s 2014 IRP in abeyance or to dismiss those protests without prejudice. PNM responded on June 13, 2016 and requested that the NMPRC dismiss the case with prejudice. The NMPRC has not yet acted on its Notice of Proposed Dismissal or the request filed on May 31, 2016. PNM is not able to predict the potential outcome of this matter but does not anticipate the NMPRC will take any further action. 2017 IRP PNM filed its 2017 IRP on July 3, 2017. The 2017 IRP addresses the 20 -year planning period, from 2017 through 2036 and includes an action plan describing PNM’s plan to implement the 2017 IRP in the four -year period following its filing. The 2017 IRP analyzed several scenarios utilizing assumptions that PNM continues service from its SJGS capacity beyond mid-2022 and that PNM retires its capacity after mid-2022. Key findings of the 2017 IRP included, among other things, that retiring PNM’s share of SJGS in 2022 and existing ownership in Four Corners in 2031 would provide long-term cost savings for PNM’s customers and that the best mix of new resources to replace the retired coal generation would include solar energy and flexible natural gas-fired peaking capacity as well as energy storage, if the economics support it, and wind energy provided additional transmission capacity becomes available. The 2017 IRP also indicated that PNM should retain the currently leased capacity in PVNGS. See additional discussion of PNM’s leased capacity in PVNGS below and in Note 8. Protests to the 2017 IRP were filed by several parties. The issues addressed in the protests included the future of PNM’s interests in SJGS, Four Corners, and PVNGS and the timing of future procurement of renewable resources. On December 19, 2018, after public hearings and consideration of the Hearing Examiner’s recommendations, the NMPRC issued a final order accepting PNM’s 2017 IRP as compliant with applicable statute and NMPRC rules. On January 18, 2019, the Board of the County of Commissioners for San Juan County, New Mexico, the City of Farmington, New Mexico, and other parties filed a Notice of Appeal with the NM Supreme Court regarding the NMPRC’s final order in PNM’s 2017 IRP. On January 18, 2019, NEE submitted a motion requesting the NMPRC reconsider its acceptance of PNM’s 2017 IRP and alleging informational inadequacy and deficiencies in PNM’s filing, which was deemed denied. On February 19, 2019, NEE filed a motion with the NM Supreme Court to intervene in the appeal and to seek remand of the matter to the NMPRC. On March 11, 2019, PNM filed its response with the NM Supreme Court stating that the NMPRC has already considered and, by operation of law, denied NEE’s motion for reconsideration. On May 10, 2019, the appellants, excluding NEE, filed a motion with the NM Supreme Court to dismiss their appeal, which was supported by PNM. On May 31, 2019, the NM Supreme Court denied NEE’s request to remand the proceeding to the NMPRC and ordered NEE to respond to the motion to dismiss the appeal. On June 4, 2019, NEE responded that it did not oppose the appellants’ request to dismiss their appeal. On July 26, 2019, the NM Supreme Court granted the parties’ motions to dismiss the appeal. On September 19, 2019, NEE filed a second motion requesting the NMPRC reconsider its acceptance of PNM’s 2017 IRP, which was deemed denied. This matter is now concluded. As discussed below, on July 1, 2019, PNM submitted its SJGS Abandonment Application with the NMPRC requesting approval to retire SJGS in 2022, for replacement resources, and for issuance of securitized financing under the ETA. Many of the assumptions and findings included in PNM’s July 1, 2019 filing were consistent with those identified in PNM’s 2017 IRP. The SJGS Abandonment Application and the 2017 IRP are not a final determinations of PNM’s future generation portfolio. PNM will also be required to obtain NMPRC approval of an exit from Four Corners, which PNM will seek at an appropriate time in the future. Likewise, NMPRC approval of new generation resources through CCNs, PPAs, or other applicable filings will be required. 2020 IRP In the third quarter of 2019, PNM initiated its 2020 IRP process which will cover the 20 -year planning period from 2019 through 2039. Consistent with historical practice, PNM has provided notice to various interested parties and has hosted a series of public advisory presentations. NMPRC rules require PNM to file its 2020 IRP in July 2020. PNM will continue to seek input from interested parties as a pa |

Income Taxes | Income Taxes Federal Income Tax Reform On December 22, 2017, comprehensive changes in U.S. federal income taxes were enacted through legislation commonly known as the Tax Cuts and Jobs Act (the “Tax Act”). The Tax Act made many significant modifications to the tax laws, including reducing the federal corporate income tax rate from 35% to 21% effective January 1, 2018. The Tax Act also eliminated federal bonus depreciation for utilities, limited interest deductibility for non-utility businesses and limited the deductibility of officer compensation. During 2019, the IRS issued proposed regulations related to certain officer compensation and proposed regulations on interest deductibility that provide a 10% “de minimis” exception that allows entities with predominantly regulated activities to fully deduct interest expenses. In addition, the IRS issued proposed regulations interpreting Tax Act amendments to depreciation provisions of the IRC that allow the Company to claim a bonus depreciation deduction on certain construction projects placed in service subsequent to the third quarter of 2017. Although most of the provisions of the Tax Act were not effective until 2018, GAAP required that some effects be recognized in 2017. Under the asset and liability method of accounting for income taxes used by the Company, deferred tax assets and liabilities are recognized for the future tax consequences of temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. The deferred tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income in the years in which the temporary differences are expected to reverse. At the date of enactment of the Tax Act, the Company had net deferred tax liabilities for its regulated activities and net deferred tax assets for non-regulated activities. As a result of the change in the federal income tax rate, the Company re-measured and adjusted its deferred tax assets and liabilities as of December 31, 2017. The portion of that adjustment not related to PNM’s and TNMP’s regulated activities was recorded as a reduction in net deferred tax assets and an increase in income tax expense. The portion related to PNM’s and TNMP’s regulated activities was recorded as a reduction in net deferred tax liabilities and an increase in regulatory liabilities. Beginning February 2018, PNM’s NM 2016 Rate Case reflects the reduction in the federal corporate income tax rate, including amortization of excess deferred federal and state income taxes. In accordance with the order in that case, PNM is returning the protected portion of excess deferred federal income taxes to customers over the average remaining life of plant in service as of December 31, 2017, the unprotected portion of excess deferred federal income taxes to customers over a period of approximately twenty-three years , and excess deferred state income taxes to customers over a period of three years. The approved settlement in the TNMP 2018 Rate Case includes a reduction in customer rates to reflect the impacts of the Tax Act beginning on January 1, 2019. See additional discussion of PNM’s NM 2016 Rate Case and TNMP’s 2018 Rate Case in Note 17. The adjustments to deferred income taxes recorded as increases in regulatory liabilities and income tax expense as a result of the enactment of the Tax Act at December 31, 2017 are presented below: PNM TNMP Corporate and Other Consolidated (In thousands) Net increase in regulatory liabilities $ 402,501 $ 146,451 $ — $ 548,952 Net decrease in deferred income tax liabilities (deferred income tax assets) 372,895 138,586 (19,990 ) 491,491 Net deferred income tax expense $ 29,606 $ 7,865 $ 19,990 $ 57,461 GAAP requires that the impacts of adjusting existing deferred tax assets and liabilities for a change in an income tax rate be recognized in income tax expense during the period of enactment, including impacts that are reflected in AOCI. This resulted in the tax effects of items within AOCI not reflecting the appropriate tax rate and being stranded in AOCI. In February 2018, the FASB issued Accounting Standards Update 2018-02 - Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income to address this issue by allowing entities to reclassify the income tax effects of the Tax Act on items within AOCI to retained earnings. The Company records in AOCI, net of income taxes, unamortized gains and losses related to PNM’s defined benefit pension plans to the extent not attributed to regulated operations, unrealized gains on PNM’s available-for-sale debt securities, and unrealized gains and losses on cash flow hedges related to PNMR’s interest rate swaps. When amounts are reclassified from AOCI to the Consolidated Statement of Earnings, the Company recognizes the related income tax expense (benefit) at the tax rate in effect at that time. As permitted by ASU 2018-02, as of December 31, 2017, the Company reclassified the stranded federal income tax effects of the Tax Act on items recorded in AOCI, resulting in a net increase in retained earnings of $17.6 million . See Note 3. In December 2017, the SEC issued Staff Accounting Bulletin No. 118 (“SAB 118”), which provided guidance to address the application of GAAP to reflect the Tax Act in circumstances where all information and analysis was not yet available or complete. This bulletin provided for a one -year period in which to complete the required analyses and accounting for the impacts of the Tax Act. In accordance with SAB 118, the Company completed its analysis of the impacts of the Tax Act in 2018. The adjustments to deferred income taxes resulting from completion of the Company’s analysis, which resulted primarily from differences between the estimated amounts recorded as of December 31, 2017 and the actual amounts reflected in the Company’s 2017 tax return filing, including adjustments resulting from additional guidance and interpretations to the Tax Act issued in 2018 related to bonus depreciation, certain incentive compensation, and other items are presented below: PNM TNMP Corporate and Other Consolidated (In thousands) Net increase (decrease) in regulatory liabilities $ 11,244 $ (4,069 ) $ — $ 7,175 Net decrease in deferred income tax liabilities (deferred income tax assets) (2,175 ) (9,784 ) 13,869 1,910 Net increase in affiliate receivables (affiliate payables) 12,300 4,042 (16,342 ) — Net deferred income tax expense $ 1,119 $ 1,673 $ 2,473 $ 5,265 As discussed in Note 17, the NM Supreme Court issued a decision in May 2019 on the appeal of the NM 2015 Rate Case resulting in pre-tax impairments of $150.6 million in the year ending December 31, 2019. The impairments were recognized as discrete items within regulatory disallowances and restructuring costs resulting in tax benefits of $45.7 million , which is reflected in income taxes on the Company’s Consolidated Statements of Earnings for the year ended December 31, 2019.

A reconciliation of unrecognized tax benefits is as follows: PNMR PNM TNMP (In thousands) Balance at December 31, 2016 $ 6,752 $ 3,949 $ — Additions based on tax positions related to 2017 262 262 — Additions (reductions) for tax positions of prior years 2,415 2,352 63 Settlement payments — — — Balance at December 31, 2017 9,429 6,563 63 Additions based on tax positions related to 2018 543 543 — Additions (reductions) for tax positions of prior years 222 182 40 Settlement payments — — — Balance at December 31, 2018 10,194 7,288 103 Additions based on tax positions related to 2019 329 329 — Additions (reductions) for tax positions of prior years 170 159 11 Settlement payments — — — Balance at December 31, 2019 $ 10,693 $ 7,776 $ 114 Included in the balance of unrecognized tax benefits at December 31, 2019 are $10.1 million , $7.2 million , and $0.1 million that, if recognized, would affect the effective tax rate for PNMR, PNM, and TNMP. The Company does not anticipate that any unrecognized tax expenses or unrecognized tax benefits will be reduced or settled in 2020 . PNMR, PNM, and TNMP had no estimated interest income or expense for the years ended December 31, 2019, 2018, and 2017. There was no accumulated accrued interest receivable or payable related to income taxes as of December 31, 2019 and 2018. The Company files a federal consolidated and several consolidated and separate state income tax returns. The tax years prior to 2015 are closed to examination by either federal or state taxing authorities other than Arizona. The tax years prior to 2014 are closed to examination by Arizona taxing authorities. Other tax years are open to examination by federal and state taxing authorities and net operating loss carryforwards are open to examination for the years in which the carryforwards are utilized. At December 31, 2019 , the Company has $286.6 million of federal net operating loss carryforwards that expire beginning in 2030 and $101.2 million of federal tax credit carryforwards that expire beginning in 2023. State net operating losses expire beginning in 2035 and vary from federal due to differences between state and federal tax law. In 2013, New Mexico House Bill 641 reduced the New Mexico corporate income tax rate from 7.6% to 5.9% . The rate reduction was being phased-in from 2014 to 2018. In accordance with GAAP, PNMR and PNM adjusted accumulated deferred income taxes to reflect the tax rate at which the balances are expected to reverse during the period that includes the date of enactment, which was in the year ended December 31, 2013. At that time, the portion of the adjustment related to PNM’s regulated activities was recorded as a reduction in deferred tax liabilities and an increase in a regulatory liability, based on the assumption that PNM would be required to return the benefit to customers over time. PNM’s NM 2016 Rate Case (Note 17) reflects the benefit of the lower New Mexico corporate income tax rate being returned to customers over a three-year period beginning February 1, 2018. In addition, the portion of the adjustment that was not related to PNM’s regulated activities was recorded as a reduction in deferred tax assets and an increase in income tax expense. Changes in the estimated timing of reversals of deferred tax assets and liabilities resulted in refinements of the impacts of this change in tax rates being recorded through December 31, 2017, at which time the impacts of the rate reduction were fully phased-in. Adjustments to deferred income taxes recorded as increases (decreases) in the regulatory liability and income tax expense were as follows: PNMR PNM TNMP (In thousands) December 31, 2017: Regulatory liability $ (10,109 ) $ (10,109 ) $ — Income tax expense $ (1,259 ) $ (1,179 ) $ — In 2008, fifty percent bonus tax depreciation was enacted as a temporary two -year stimulus measure as part of the Economic Stimulus Act of 2008. Bonus tax depreciation in various forms has been continuously extended since that time, including by the Protecting Americans from Tax Hikes Act of 2015. The 2015 act extended and phased-out bonus tax depreciation through 2019. As discussed above the Tax Act eliminated bonus depreciation for utilities effective September 28, 2017. However, in 2018 the IRS issued proposed regulations interpreting Tax Act amendments to depreciation provisions of the IRC which allowed the Company to claim a bonus depreciation deduction on certain construction projects placed in service after the third quarter of 2017. As a result of the net operating loss carryforwards for income tax purposes created by bonus depreciation, certain tax carryforwards were not expected to be utilized before their expiration. In addition, as a result of Tax Act changes to the deductibility of officer compensation, certain deferred tax benefits related to compensation are not expected to be realized. In accordance with GAAP, the Company has impaired the deferred tax assets for tax carryforwards which are not expected to be utilized and for compensation that is not expected to be deductible. The impairments after reflecting the expiration of carryforwards under applicable tax laws, net of federal tax benefit, for 2017 through 2019 are as follows: PNMR PNM TNMP (In thousands) December 31, 2019: State tax credit carryforwards $ 425 $ — $ — State net operating loss carryforwards $ — $ — $ — Charitable contribution carryforwards $ — $ — $ — Compensation expense $ (99 ) $ (100 ) $ 2 December 31, 2018: State tax credit carryforwards $ — $ — $ — State net operating loss carryforwards $ — $ — $ — Charitable contribution carryforwards $ — $ — $ — Compensation expense $ 410 $ 298 $ 111 December 31, 2017: State tax credit carryforwards $ — $ — $ — State net operating loss carryforwards $ 819 $ 627 $ — Charitable contribution carryforwards $ 909 $ — $ — The impairments of unexpired state tax credits, state net operating loss, and charitable contribution carryforwards are reflected as a valuation allowance against deferred tax assets. The reserve balances, after reflecting expiration of carryforwards under applicable tax laws, at December 31, 2019 and 2018 are as follows: PNMR PNM TNMP (In thousands) December 31, 2019: State tax credit carryforwards $ 425 $ — $ — State net operating loss carryforwards $ — $ — $ — Charitable contribution carryforwards $ — $ — $ — Compensation expense $ 311 $ 198 $ 113 December 31, 2018: State tax credit carryforwards $ — $ — $ — State net operating loss carryforwards $ — $ — $ — Charitable contribution carryforwards $ — $ — $ — Compensation expense $ 410 $ 298 $ 111 |

Goodwill and Intangible Assets Disclosure [Abstract] | |
Goodwill | Goodwill The excess purchase price over the fair value of the assets acquired and the liabilities assumed by PNMR for its 2005 acquisition of TNP was recorded as goodwill and was pushed down to the businesses acquired. In 2007, the TNMP assets that were included in its New Mexico operations, including goodwill, were transferred to PNM. PNMR’s reporting units that currently have goodwill are PNM and TNMP. GAAP requires the Company to evaluate its goodwill for impairment annually at the reporting unit level or more frequently if circumstances indicate that the goodwill may be impaired. Application of the impairment test requires judgment, including the identification of reporting units, assignment of assets and liabilities to reporting units, and determination of the fair value of each reporting unit. GAAP provides that in certain circumstances an entity may perform a qualitative analysis to conclude that the goodwill of a reporting unit is not impaired. Under a qualitative assessment an entity considers macroeconomic conditions, industry and market considerations, cost factors, overall financial performance, other relevant entity-specific events affecting a reporting unit, as well as whether a sustained decrease (both absolute and relative to its peers) in share price has occurred. An entity considers the extent to which each of the adverse events and circumstances identified could affect the comparison of a reporting unit’s fair value with its carrying amount. An entity places more weight on the events and circumstances that most affect a reporting unit’s fair value or the carrying amount of its net assets. An entity also considers positive and mitigating events and circumstances that may affect its determination of whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. An entity evaluates, on the basis of the weight of evidence, the significance of all identified events and circumstances in the context of determining whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. A quantitative analysis is not required if, after assessing events and circumstances, an entity determines that it is not more likely than not that the fair value of a reporting unit is less than its carrying amount. In other circumstances, an entity may perform a quantitative analysis to reach the conclusion regarding impairment with respect to a reporting unit. An entity may choose to perform a quantitative analysis without performing a qualitative analysis and may perform a qualitative analysis for certain reporting units, but a quantitative analysis for others. The first step of the quantitative impairment test requires an entity to compare the fair value of the reporting unit with its carrying value, including goodwill. If as a result of this analysis, the entity concludes there is an indication of impairment in a reporting unit having goodwill, GAAP currently requires the entity to perform the second step of the impairment analysis, determining the amount of goodwill impairment to be recorded. The amount is calculated by comparing the implied fair value of the goodwill to its carrying amount. This exercise would require the entity to allocate the fair value determined in step one to the individual assets and liabilities of the reporting unit. Any remaining fair value would be the implied fair value of goodwill on the testing date. To the extent the recorded amount of goodwill of a reporting unit exceeds the implied fair value determined in step two, an impairment loss would be reflected in results of operations. As further discussed under New Accounting Pronouncements in Note 1, a new accounting pronouncement changes how goodwill impairment is determined by eliminating the second step of the quantitative impairment analysis. PNMR periodically updates its quantitative analysis for both PNM and TNMP. The use of a quantitative approach in a given period is not necessarily an indication that a potential impairment has been identified under a qualitative approach. When PNMR performs a quantitative analysis for PNM or TNMP, a discounted cash flow methodology is primarily used to estimate the fair value of the reporting unit. This analysis requires significant judgments, including estimations of future cash flows, which is dependent on internal forecasts, estimations of long-term growth rates for the business, and determination of appropriate weighted average cost of capital for the reporting unit. Changes in these estimates and assumptions could materially affect the determination of fair value and the conclusion of impairment. When PNMR performs a qualitative or quantitative analysis for PNM or TNMP, PNMR considers market and macroeconomic factors including changes in growth rates, changes in the WACC, and changes in discount rates. The Company also evaluates its stock price relative to historical performance, industry peers, and to major market indices, including an evaluation of the Company’s market capitalization relative to the carrying value of its reporting units. For its annual evaluations performed as of April 1, 2019, PNMR performed qualitative analyses for both the PNM and TNMP reporting units. The qualitative analysis was performed by considering changes in the Company’s expectations of future financial performance since the April 1, 2018 quantitative analysis performed for PNM, as well as the quantitative analysis performed for TNMP at April 1, 2016 and the qualitative analyses through April 1, 2018. This analysis considered Company specific events such as the potential impacts of legal and regulatory matters discussed in Note 16 and Note 17, including potential outcomes in PNM’s SJGS Abandonment Application, the impacts of the NM Supreme Court’s decision in the appeal of the NM 2015 Rate Case, and other potential impacts of changes in PNM’s resource needs based on PNM’s 2017 IRP. Based on an evaluation of these and other factors, the Company determined it was not more likely than not that the April 1, 2019 carrying values of PNM or TNMP exceeded their fair values. For the annual evaluations performed as of April 1, 2018, PNMR utilized a quantitative analysis for the PNM reporting unit and a qualitative analysis for the TNMP reporting unit. The April 1, 2018 quantitative evaluations indicated the fair value of the PNM reporting unit, which has goodwill of $51.6 million , exceeded its carrying value by approximately 19% . The 2018 qualitative analysis for the TNMP reporting unit was performed by considering changes in expectations of future financial performance since the April 1, 2016 quantitative analysis that indicated the fair value of the TNMP reporting unit, which has goodwill of $226.7 million , exceeded its carrying value by approximately 32% . The 2018 analysis considered events specific to TNMP such as the potential impacts of legal and regulatory matters discussed in Note 16 and Note 17, including potential adverse outcomes in the then pending TNMP 2018 Rate Case. Based on an evaluation of these and other factors, the Company determined it is not more likely than not that the April 1, 2018 carrying values of PNM or TNMP exceed their fair values. For the April 1, 2017 evaluation for both the PNM and TNMP reporting units, the qualitative analyses were performed by considering changes in the Company’s expectations of future financial performance since the April 1, 2016 quantitative analyses. These analyses considered Company specific events such as the potential impacts of legal and regulatory matters discussed in Note 16 and Note 17, including the estimated impacts of the proposed revised stipulation in the PNM NM 2016 Rate Case, the impacts of potential outcomes of the matters appealed to the NM Supreme Court under the NM 2015 Rate Case, and the impacts of changes in PNM’s resource needs based on PNM’s 2017 IRP. These evaluations also considered changes in TNMP’s regulatory environment such as the PUCT’s then proposed amendments to the interim transmission cost of service filing rule, as well as potential outcomes associated with TNMP’s general rate case filing, which the Company filed in May 2018. Based on an evaluation of these and other factors, the Company determined it is not more likely than not that the April 1, 2017 carrying values of PNM or TNMP exceed their fair values. |

Summary of the Business and Significant Accounting Policies (Policies) | 12 Months Ended |

Accounting Policies [Abstract] | |
Basis of accounting | Financial Statement Preparation and Presentation The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could ultimately differ from those estimated. |
Principles of Consolidation | Principles of Consolidation The Consolidated Financial Statements of each of PNMR, PNM, and TNMP include their accounts and those of subsidiaries in which that entity owns a majority voting interest. PNM also consolidates Valencia (Note 10). PNM owns undivided interests in several jointly-owned power plants and records its pro-rata share of the assets, liabilities, and expenses for those plants. The agreements for the jointly-owned plants provide that if an owner were to default on its payment obligations, the non-defaulting owners would be responsible for their proportionate share of the obligations of the defaulting owner. In exchange, the non-defaulting owners would be entitled to their proportionate share of the generating capacity of the defaulting owner. There have been no such payment defaults under any of the agreements for the jointly-owned plants. |
Accounting for the Effects of Certain Types of Regulation | Accounting for the Effects of Certain Types of Regulation The Company maintains its accounting records in accordance with the uniform system of accounts prescribed by FERC and adopted by the NMPRC and PUCT. Certain of the Company’s operations are regulated by the NMPRC, PUCT, and FERC and the provisions of GAAP for rate-regulated enterprises are applied to the regulated operations. Regulators may assign costs to accounting periods that differ from accounting methods applied by non-regulated utilities. When it is probable that regulators will permit recovery of costs through future rates, costs are deferred as regulatory assets that otherwise would be expensed. Likewise, regulatory liabilities are recognized when it is probable that regulators will require refunds through future rates or when revenue is collected for expenditures that have not yet been incurred. GAAP also provides for the recognition of revenue and regulatory assets and liabilities associated with “alternative revenue programs” authorized by regulators. Such programs allow the utility to adjust future rates in response to past activities or completed events, if certain criteria are met, even for programs that do not otherwise qualify for recognition of regulatory assets and liabilities. Regulatory assets and liabilities are amortized into earnings over the authorized recovery period. Accordingly, the Company has deferred certain costs and recorded certain liabilities pursuant to the rate actions of the NMPRC, PUCT, and FERC. Information on regulatory assets and regulatory liabilities is contained in Note 13. In some circumstances, regulators allow a requested increase in rates to be implemented, subject to refund, before the regulatory process has been completed and a decision rendered by the regulator. When this occurs, the Company assesses the possible outcomes of the rate proceeding. The Company records a provision for refund to the extent the amounts being collected, subject to refund, exceed the amount the Company determines is probable of ultimately being allowed by the regulator. |
Cash and Cash Equivalents | Cash and Restricted Cash Investments in highly liquid investments with original maturities of three months or less at the date of purchase are considered cash and cash equivalents. |
Utility Plant | Utility Plant Utility plant is stated at original cost and includes capitalized payroll-related costs such as taxes, pension, other fringe benefits, administrative costs, and AFUDC, where authorized by rate regulation, or capitalized interest. Repairs, including major maintenance activities, and minor replacements of property are expensed when incurred, except as required by regulators for ratemaking purposes. Major replacements are charged to utility plant. Gains, losses, and costs to remove resulting from retirements or other dispositions of regulated property in the normal course of business are credited or charged to accumulated depreciation. PNM and TNMP may receive reimbursements, referred to as CIAC, from customers to pay for all or part of certain construction projects to the extent the project does not benefit regulated customers in general. PNM and TNMP account for these reimbursements as offsets to utility plant additions based on the requirements of the NMPRC, FERC, and PUCT. Due to the PUCT’s regulatory treatment of CIAC reimbursements, TNMP also receives a financing component that is recognized as other income on the Consolidated Statements of Earnings. Under the NMPRC regulatory treatment, PNM typically does not receive a financing component. |
Depreciation and Amortization | Depreciation and Amortization |
Allowance for Funds Used During Construction | Allowance for Funds Used During Construction As provided by the FERC uniform systems of accounts, AFUDC is charged to regulated utility plant for construction projects. This allowance is designed to enable a utility to capitalize financing costs during periods of construction of property subject to rate regulation. It represents the cost of borrowed funds (allowance for borrowed funds used during construction or “debt AFUDC”) and a return on other funds (allowance for equity funds used during construction or “equity AFUDC”). The debt AFUDC is recorded in interest charges and the equity AFUDC is recorded in other income on the Consolidated Statements of Earnings. |
Materials, Supplies, and Fuel Stock | Materials, Supplies, and Fuel Stock Materials and supplies relate to transmission, distribution, and generating assets. Materials and supplies are charged to inventory when purchased and are expensed or capitalized as appropriate when issued. Materials and supplies are valued using an average costing method. Coal is valued using a rolling weighted average costing method that is updated based on the current period cost per ton. Periodic aerial surveys are performed on the coal piles and adjustments are made. Average cost is equal to net realizable value under the ratemaking process. |
Investments | Investments PNM holds investment securities in the NDT for the purpose of funding its share of the decommissioning costs of PVNGS and trusts for PNM’s share of final reclamation costs related to the coal mines serving SJGS and Four Corners (Note 16). Since third party investment managers have sole discretion over the purchase and sale of the securities, PNM records a realized loss as an impairment for any available-for-sale debt security that has a market value that is less than cost at the end of each quarter. Prior to 2018, PNM classified all debt and equity investments in the NDT and coal mine reclamation trusts as available-for-sale securities. Effective January 1, 2018, the Company adopted Accounting Standards Update 2016-01 – Financial Instruments (Subtopic 825-10), which eliminates the requirement to classify investments in equity securities with readily determinable fair values into trading or available-for-sale categories and requires those equity securities to be measured at fair value with changes in fair value recognized in earnings rather than in OCI. On January 1, 2018, PNM recorded a cumulative effect adjustment to reclassify unrealized holding gains on equity securities held in the NDT and coal mine reclamation trusts from AOCI to retained earnings on the Consolidated Balance Sheets. Accordingly, the information for investment securities in the NDT and coal mine reclamation trusts for 2019 and 2018 is presented under ASU 2016-01 and the information for 2017 is presented under prior GAAP. For the years ended December 31, 2019 and 2018, PNM recorded impairment losses on the available-for-sale debt securities of $5.7 million and $13.7 million . For the year ended December 31, 2017, PNM recorded impairment losses on the available-for-sale securities, which included both debt and equity securities, of $7.1 million |
Goodwill | Goodwill |
Asset Impairment | Asset Impairment |
Revenue Recognition | Electric operating revenues are recorded in the period of energy delivery, which includes estimated amounts for service rendered but unbilled at the end of each accounting period. The determination of the energy sales billed to individual customers is based on the reading of their meters, which occurs on a systematic basis throughout the month. At the end of each month, amounts of energy delivered to customers since the date of the last meter reading and the corresponding unbilled revenue are estimated. Unbilled electric revenue is estimated based on daily generation volumes, estimated customer usage by class, line losses, historical trends and experience, and applicable customer rates. Amounts billed are generally due within the next month. The Company does not incur incremental costs to obtain contracts for its energy services. PNM’s wholesale electricity sales are recorded as electric operating revenues and wholesale electricity purchases are recorded as costs of energy sold. In accordance with GAAP, derivative contracts that are subject to unplanned netting are recorded net in earnings. A “book-out” is the planned or unplanned netting of off-setting purchase and sale transactions. A book-out is a transmission mechanism to reduce congestion on the transmission system or administrative burden. For accounting purposes, a book-out is the recording of net revenues upon the settlement of a derivative contract. Unrealized gains and losses on derivative contracts that are not designated for hedge accounting are classified as economic hedges. Economic hedges are defined as derivative instruments, including long-term power and fuel supply agreements, used to hedge generation assets and purchased power costs. Changes in the fair value of economic hedges are reflected in results of operations, with changes related to economic hedges on sales included in operating revenues and changes related to economic hedges on purchases included in cost of energy sold. See Note 9. The Company adopted ASU 2014-09 – Revenue from Contracts with Customers (Topic 606) as of January 1, 2018, its required effective date, using the modified retrospective method of adoption. The adoption of ASU 2014-09 did not result in changes to the nature, amount, and timing of the Company’s existing revenue recognition processes or information technology infrastructure. Therefore, the adoption of ASU 2014-09 had no effect on the amount of revenue recorded in 2018 compared to the amount that would have been recorded under prior GAAP, no effect on total electric operating revenues or any other caption within the Company’s financial statements, and no cumulative effect adjustment was recorded. Revenues for 2019 and 2018 are presented in accordance with the standard on the Consolidated Statements of Earnings and 2017 revenues are presented on a comparative basis. Additional disclosures to further disaggregate 2019 and 2018 revenues are presented below. |
Accounts Receivable and Allowance for Uncollectible Accounts | Accounts Receivable and Allowance for Uncollectible Accounts Accounts receivable consists primarily of trade receivables from customers. In the normal course of business, credit is extended to customers on a short-term basis. The Company calculates the allowance for uncollectible accounts based on historical experience and estimated default rates. The accounts receivable balances are reviewed monthly and adjustments to the allowance for uncollectible accounts and bad debt expense are made as necessary. Amounts that are deemed uncollectible are written off. |
Amortization of Debt Acquisition Costs | Amortization of Debt Acquisition Costs Discount, premium, and expense related to the issuance of long-term debt are amortized over the lives of the respective issues. Gains and losses incurred upon the early retirement of long-term debt are recognized in other income or other deductions, except for amounts recoverable through NMPRC, FERC, or PUCT regulation, which are recorded as regulatory assets or liabilities and amortized over the lives of the respective issues. Unamortized premium, discount, and expense related to long-term debt are reflected as part of the related liability on the Consolidated Balance Sheets. |
Derivatives | Derivatives The Company records derivative instruments, including energy contracts, on the balance sheet as either an asset or liability measured at their fair value. GAAP requires that changes in the derivatives’ fair value be recognized currently in earnings unless specific hedge accounting criteria are met. PNM also records certain commodity derivative transactions recoverable through NMPRC regulation as regulatory assets or liabilities. See Note 7 and Note 9. Accounting for Derivatives Under derivative accounting and related rules for energy contracts, PNM accounts for its various instruments for the purchase and sale of energy, which meet the definition of a derivative, based on PNM’s intent. During the years ended December 31, 2019 , 2018 , and 2017 , PNM was not hedging its exposure to the variability in future cash flows from commodity derivatives through designated cash flows hedges. The derivative contracts recorded at fair value that do not qualify or are not designated for cash flow hedge accounting are classified as economic hedges. Economic hedges are defined as derivative instruments, including long-term power agreements, used to economically hedge generation assets, purchased power and fuel costs, and customer load requirements. Changes in the fair value of economic hedges are reflected in results of operations and are classified between operating revenues and cost of energy according to the intent of the hedge. PNM has no trading transactions. |
Decommissioning and Reclamation Costs | Decommissioning and Reclamation Costs In accordance with GAAP, PNM is only required to recognize and measure decommissioning liabilities for tangible long-lived assets for which a legal obligation exists. Nuclear decommissioning costs and related accruals are based on periodic site-specific estimates of the costs for removing all radioactive and other structures at PVNGS and are dependent upon numerous assumptions, including estimates of future decommissioning costs at current price levels, inflation rates, and discount rates. PNM’s accruals for PVNGS Units 1, 2, and 3, including portions held under leases, have been made based on such estimates, the guidelines of the NRC, and the PVNGS license periods. PVNGS Units 1 and 2 are included in PNM’s retail rates and PVNGS Unit 3 was excluded through December 31, 2017 but is included in retail rates beginning in 2018. See Note 16. See Note 17 for information concerning the treatment of nuclear decommissioning costs for certain purchased and leased portions of PVNGS in the NMPRC’s order in PNM’s NM 2015 Rate Case and the NM Supreme Court’s decision on PNM’s appeal of that order. |
Environmental Costs | Environmental Costs The normal operations of the Company involve activities and substances that expose the Company to potential liabilities under laws and regulations protecting the environment. Liabilities under these laws and regulations can be material and may be imposed without regard to fault, or may be imposed for past acts, even though the past acts may have been lawful at the time they occurred. |
Income Taxes | Income Taxes Income taxes are recognized using the asset and liability method of accounting for income taxes. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying value of existing assets and liabilities and their respective tax basis. In accordance with GAAP, all deferred taxes are reflected as non-current on the Consolidated Balance Sheets. Current NMPRC, FERC, and PUCT approved rates include the tax effects of the majority of these differences. GAAP requires that rate-regulated enterprises record deferred income taxes for temporary differences accorded flow-through treatment at the direction of a regulatory commission. The resulting deferred tax assets and liabilities are recorded based on the expected cash flow to be reflected in future rates. Because the NMPRC, FERC, and the PUCT have consistently permitted the recovery of tax effects previously flowed-through earnings, the Company has established regulatory assets and liabilities offsetting such deferred tax assets and liabilities. The Company recognizes only the impact of tax positions that, based on their merits, are more likely than not to be sustained upon an IRS audit. The Company defers investment tax credits and amortizes them over the estimated useful lives of the assets. See Note 18 for additional information, including a discussion of the impacts of the Tax Act. The Company makes an estimate of its anticipated effective tax rate for the year as of the end of each quarterly period within its fiscal year. In interim periods, income tax expense is calculated by applying the anticipated annual effective tax rate to year-to-date earnings before taxes, which includes the earnings attributable to the Valencia non-controlling interest. GAAP also provides that certain unusual or infrequently occurring items, as well as adjustments due to enactment of new tax laws, be excluded from the estimated annual effective tax rate calculation. |
New Accounting Pronouncements | New Accounting Pronouncements Information concerning recently issued accounting pronouncements that have not been adopted by the Company is presented below. The Company does not expect difficulty in adopting these standards by their required effective dates. Accounting Standards Update 2016-13 – Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments In June 2016, the FASB issued ASU 2016-13, which changes the way entities recognize impairment of many financial assets, including accounts receivable and investments in certain debt securities, by requiring immediate recognition of estimated credit losses expected to occur over the remaining lives of the assets. In November 2018, the FASB clarified that receivables arising from operating leases are not within the scope of Topic 326 for assets measured at amortized costs. Instead, impairments of receivables arising from operating leases should be accounted for in accordance with Topic 842. In May 2019, the FASB issued transition relief by providing an option to irrevocably elect the fair value option for certain financial assets previously measured at amortized cost. The Company is in the process of analyzing the impacts of the new standard but does not anticipate a significant impact on its reserves for trade receivables or on PNMR’s guarantees of certain PNMR Development debt arrangements. A cumulative effect adjustment is also not anticipated upon implementation. ASU 2016-13 also requires entities to separately measure and realize an impairment for credit losses on available-for-sale debt securities for which carrying value exceeds fair value, unless such securities have been determined to be other than temporarily impaired and the entire decrease in value has been realized as an impairment. PNM records a realized loss as an impairment for any available-for-sale debt security that has a fair value that is less than carrying value at the end of each quarter. As a result, the Company does not anticipate the new standard will impact its accounting for available-for-sale debt securities. The Company will adopt ASU 2016-13 as of January 1, 2020, its required effective date. Accounting Standards Update 2017-04 – Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment In January 2017, the FASB issued ASU 2017-04 to simplify the annual goodwill impairment assessment process. Currently, the first step of a quantitative impairment test requires an entity to compare the fair value of each reporting unit containing goodwill with its carrying value (including goodwill). If as a result of this analysis, the entity concludes there is an indication of impairment in a reporting unit having goodwill, the entity is required to perform the second step of the impairment analysis, determining the amount of goodwill impairment to be recorded. The amount is calculated by comparing the implied fair value of the goodwill to its carrying amount. This exercise requires the entity to allocate the fair value determined in step one to the individual assets and liabilities of the reporting unit. Any remaining fair value would be the implied fair value of goodwill on the testing date. To the extent the recorded amount of goodwill of a reporting unit exceeds the implied fair value determined in step two, an impairment loss would be reflected in results of operations. ASU 2017-04 eliminates the second step of the impairment analysis. Accordingly, if the first step of a quantitative goodwill impairment analysis performed after adoption of ASU 2017-04 indicates that the fair value of a reporting unit is less than its carrying value, the goodwill of that reporting unit would be impaired to the extent of that difference. The Company will adopt ASU 2017-04 for impairment testing after January 1, 2020, its required effective date. Accounting Standards Update 2018-13 – Fair Value Measurements (Topic 820) Disclosure Framework: Changes to the Disclosure Requirements for Fair Value Measurements In August 2018, the FASB issued ASU 2018-13 to improve fair value disclosures. ASU 2018-13 eliminates certain disclosure requirements related to transfers between Levels 1 and 2 of the fair value hierarchy and the requirement to disclose the valuation process for Level 3 fair value measurements. ASU 2018-13 also amends certain disclosure requirements for investments measured at net asset value and requires new disclosures for Level 3 investments, including a new requirement to disclose changes in unrealized gains or losses recorded in OCI related to Level 3 fair value measurements. ASU 2018-13 is effective for the Company beginning on January 1, 2020 and permits entities to adopt all or certain elements of the new guidance prior to its effective date. ASU 2018-13 requires retrospective application, except for the new disclosures related to Level 3 investments which are to be applied prospectively. As discussed in Note 9, PNM and TNMP have investment securities in trusts for decommissioning, reclamation, pension benefits, and other postretirement benefits, which are measured at fair value. Certain investments in these trusts are measured at net asset value per share. These trusts currently hold no Level 3 investments. The Company is evaluating the requirements of ASU 2018-13, but does not anticipate it will have a significant impact on the Company’s fair value disclosures. Accounting Standards Update 2018-14 – Compensation - Retirement Benefits - Defined Benefit Plans (Topic 715) Disclosure Framework: Changes to the Disclosure Requirements for Defined Benefit Plans In August 2018, the FASB issued ASU 2018-14 to improve benefit plan sponsors’ disclosures for defined benefit pension and other post-employment benefit plans. ASU 2018-14 removes the requirement to disclose the amounts in other comprehensive income expected to be recognized as benefit cost over the next fiscal year and the requirement to disclose the impact of a one-percentage-point change in the assumed health care cost trend rate; clarifies the disclosure requirements for plans with assets that are less than their projected benefit, or accumulated benefit obligation; and requires significant gains and losses affecting benefit obligations during the period be disclosed. ASU 2018-14 is effective for the Company on December 31, 2020, although early adoption is permitted, and requires retrospective application. As discussed in Note 11, PNM and TNMP maintain qualified defined benefit, other postretirement benefit plans providing medical and dental benefits, and executive retirement programs. The Company is in the process of evaluating the requirements of ASU 2018-14 but does not anticipate these changes will have a significant impact on the Company’s defined benefit and other postretirement benefit plan disclosures. Accounting Standards Update 2018-15 – Intangibles - Goodwill and Other - Internal Use Software (Topic 350): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract In August 2018, the FASB issued ASU 2018-15 to align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for implementation costs incurred to develop or obtain internal-use software. Under ASU 2018-15, entities are required to capitalize implementation costs for hosting arrangements if those costs meet the capitalization requirements for internal-use software arrangements. ASU 2018-15 requires entities to present cash flows, capitalized costs, and amortization expense in the same financial statement line items as other costs incurred for such hosting arrangements. ASU 2018-15 is effective for the Company on January 1, 2020 and allows entities to apply the new requirements retrospectively or prospectively. The Company is in the process of analyzing the impacts of this new standard. Accounting Standards Update 2019-12 – Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes In December 2019, the FASB issued ASU 2019-12 as part of its initiative to reduce complexity in accounting standards. The amendments in ASU 2019-12 simplify accounting for income taxes by removing several accounting exceptions to accounting for income taxes. ASU 2019-12 also eliminates or simplifies other income tax accounting requirements, including a requirement that entities recognize franchise tax (or similar tax) that is partially based on income as an income-based tax. ASU 2019-12 is effective for the Company beginning on January 1, 2021 and allows for early adoption. ASU 2019-12 is to be applied prospectively or retrospectively in the period of adoption depending on the type of amendment. The Company is in the process of analyzing the impacts of this new standard. |
Segment Information | The following segment presentation is based on the methodology that management uses for making operating decisions and assessing performance of its various business activities. A reconciliation of the segment presentation to the GAAP financial statements is provided. |
Fair Value of Derivatives | The Company determines the fair values of its derivative and other financial instruments based on the hierarchy established in GAAP, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. GAAP describes three levels of inputs that may be used to measure fair value. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability. The Company records any transfers between fair value hierarchy levels as of the end of each calendar quarter. There were no transfers between levels during the year ended December 31, 2018 . See New Accounting Pronouncements in Note 1. For investment securities, Level 2 and Level 3 fair values are provided by fund managers utilizing a pricing service. For Level 2 fair values, the pricing provider predominantly uses the market approach using bid side market value based upon a hierarchy of information for specific securities or securities with similar characteristics. Fair values of Level 2 investments in mutual funds are equal to net asset value. Level 3 investments at December 31, 2018 were comprised of corporate term loans. For commodity derivatives, Level 2 fair values are determined based on market observable inputs, which are validated using multiple broker quotes, including forward price, volatility, and interest rate curves to establish expectations of future prices. Credit valuation adjustments are made for estimated credit losses based on the overall exposure to each counterparty. For the Company’s long-term debt, Level 2 fair values are provided by an external pricing service. The pricing service primarily utilizes quoted prices for similar debt in active markets when determining fair value. The valuation of Level 3 investments requires significant judgment by the pricing provider due to the absence of quoted market values, changes in market conditions, and the long-term nature of the assets. The significant unobservable inputs include the trading multiples of public companies that are considered comparable to the company being valued, company specific issues, estimates of liquidation value, current operating performance and future expectations of performance, changes in market outlook and the financing environment, capitalization rates, discount rates, and cash flows. The Company has no Level 3 investments as of December 31, 2019. Management of the Company independently verifies the information provided by pricing services. |
Variable Interest Entities | GAAP determines how an enterprise evaluates and accounts for its involvement with variable interest entities, focusing primarily on whether the enterprise has the power to direct the activities that most significantly impact the economic performance of a variable interest entity (“VIE”). GAAP also requires continual reassessment of the primary beneficiary of a VIE. |
Pension and Other Postretirement Benefits | GAAP requires a plan sponsor to (a) recognize in its statement of financial position an asset for a plan’s overfunded status or a liability for a plan’s underfunded status; (b) measure a plan’s assets and its obligations that determine its funded status as of the end of the employer’s fiscal year; and (c) recognize changes in the funded status of a defined benefit postretirement plan in the year in which the changes occur. GAAP requires unrecognized prior service costs and unrecognized gains or losses to be recorded in AOCI and subsequently amortized. To the extent the amortization of these items will ultimately be recovered or returned through future rates, PNM and TNMP record the costs as a regulatory asset or regulatory liability. The amortization of these incurred costs is included as pension and postretirement benefit periodic cost or income in subsequent years. The Company maintains trust funds for the pension and OPEB plans from which benefits are paid to eligible employees and retirees. The Company’s funding policy is to make contributions to the trusts, as determined by an independent actuary, that comply with minimum guidelines of the Employee Retirement Income Security Act and the IRC. Information concerning the investments is contained in Note 9. The Company has in place a policy that defines the investment objectives, establishes performance goals of asset managers, and provides procedures for the manner in which investments are to be reviewed. The plans implement investment strategies to achieve the following objectives: • Implement investment strategies commensurate with the risk that the Corporate Investment Committee deems appropriate to meet the obligations of the pension plans and OPEB plans, minimize the volatility of expense, and account for contingencies • Transition asset mix over the long-term to a higher proportion of high-quality fixed income investments as the plans’ funded statuses improve Management is responsible for the determination of the asset target mix and the expected rate of return. The target asset allocations are determined based on consultations with external investment advisors. The expected long-term rate of return on pension and postretirement plan assets is calculated on the market-related value of assets. GAAP requires that actual gains and losses on pension and OPEB plan assets be recognized in the market-related value of assets equally over a period of not more than five years, which reduces year-to-year volatility. For the PNM Plans and TNMP Plans, the market-related value of assets is equal to the prior year’s market-related value of assets adjusted for contributions, benefit payments and investment gains and losses that are within a corridor of plus or minus 4.0% around the expected return on market value. Gains and losses that are outside the corridor are amortized over five years . In March 2017, the FASB issued Accounting Standards Update 2017-07 - Compensation - Retirement Benefits (Topic 715) to improve the presentation of net periodic pension and other postretirement benefit costs. Prior to ASU 2017-07, the Company presented all of its net periodic benefit costs, net of amounts capitalized to construction and other accounts, as administrative and general expenses on its statements of earnings. ASU 2017-07 requires the service cost component of net benefit costs be presented in the same line item or items as employees’ compensation. The other components of net periodic benefit cost (the “non-service cost components”) are required to be presented separately from the service cost component and outside of operating income. ASU 2017-07 also limits capitalization of net periodic benefit costs to only the service cost component. ASU 2017-07 requires retrospective presentation of the service and non-service cost components of net periodic benefit costs in the income statement and prospective application regarding the capitalization of only the service cost component of net periodic benefit costs. The Company adopted ASU 2017-07 as of January 1, 2018, its required effective date. In accordance with the standard, the PNM and PNMR Consolidated Statements of Earnings reflect a reclassification from administrative and general expenses to other (deductions) for the non-service cost components of net periodic benefit costs in the amount of $8.6 million , net of amounts capitalized prior to the adoption of the standard, in the year ended December 31, 2017. The non-service components of TNMP’s |
Commitments and Contingencies | There are various claims and lawsuits pending against the Company. In addition, the Company is subject to federal, state, and local environmental laws and regulations and periodically participates in the investigation and remediation of various sites. In addition, the Company periodically enters into financial commitments in connection with its business operations. Also, the Company is involved in various legal and regulatory proceedings in the normal course of its business. See Note 17. It is not possible at this time for the Company to determine fully the effect of all litigation and other legal and regulatory proceedings on its financial position, results of operations, or cash flows. With respect to some of the items listed below, the Company has determined that a loss is not probable or that, to the extent probable, cannot be reasonably estimated. In some cases, the Company is not able to predict with any degree of certainty the range of possible loss that could be incurred. The Company assesses legal and regulatory matters based on current information and makes judgments concerning their potential outcome, giving due consideration to the nature of the claim, the amount and nature of any damages sought, and the probability of success. Such judgments are made with the understanding that the outcome of any litigation, investigation, or other legal proceeding is inherently uncertain. In accordance with GAAP, the Company records liabilities for matters where it is probable a loss has been incurred and the amount of loss is reasonably estimable. The actual outcomes of the items listed below could ultimately differ from the judgments made and the differences could be material. The Company cannot make any assurances that the amount of reserves or potential insurance coverage will be sufficient to cover the cash obligations that might be incurred as a result of litigation or regulatory proceedings. Except as otherwise disclosed, the Company does not expect that any known lawsuits, environmental costs, and commitments will have a material effect on its financial condition, results of operations, or cash flows. |
