Business And Significant Accounting Policies [Abstract] | |
BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES | 1. BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES Description of Business References in this report to “we,” “our,” “us” and “the company” are to Oncor and/or its subsidiaries as apparent in the context. See “Glossary” for the definition of terms and abbreviations. We are a regulated electricity transmission and distribution company that provides the essential service of delivering electricity safely, reliably and economically to end-use consumers through our electrical systems, as well as providing transmission grid connections to merchant generation facilities and interconnections to other transmission grids in Texas. Our transmission and distribution rates are regulated by the PUCT and certain cities, and in certain limited instances, by the FERC. We are not a seller of electricity, nor do we purchase electricity for resale. We are a direct, majority-owned subsidiary of Oncor Holdings, which is indirectly and wholly owned by Sempra. Oncor Holdings owns 80.25 % of our outstanding membership interests and Texas Transmission owns 19.75 % of our outstanding membership interests. We are managed as an integrated business; consequently, there is only one reportable segment. Ring-Fencing Measures Since 2007, various ring-fencing measures have been taken to enhance our credit quality and the separateness between the Oncor Ring-Fenced Entities and entities with ownership interests in Oncor or Oncor Holdings. These ring-fencing measures serve to mitigate the Oncor Ring-Fenced Entities’ credit exposure to owners of Oncor and Oncor Holdings, and to reduce the risk that the assets and liabilities of the Oncor Ring-Fenced Entities would be substantively consolidated with the assets and liabilities of any direct or indirect owners of Oncor and Oncor Holdings in connection with a bankruptcy of any such entities. These measures include the November 2008 sale of 19.75 % of Oncor’s equity interests to Texas Transmission. In March 2018, Sempra indirectly acquired Oncor Holdings after obtaining various approvals, including PUCT approval through the Sempra Order, which outlines certain ring-fencing measures, governance mechanisms and restrictions that apply after the Sempra Acquisition. As a result of these ring-fencing measures, Sempra does not control Oncor, and the ring-fencing measures limit Sempra’s ability to direct the management, policies and operations of Oncor, including the deployment or disposition of Oncor’s assets, declarations of dividends, strategic planning and other important corporate issues and actions. None of the assets of the Oncor Ring-Fenced Entities are available to satisfy the debt or obligations of any Sempra entity or any other direct or indirect owner of Oncor or Oncor Holdings. The assets and liabilities of the Oncor Ring-Fenced Entities are separate and distinct from those of any Sempra entities and any other direct or indirect owner of Oncor or Oncor Holdings. We do not bear any liability for debt or contractual obligations of Sempra and its affiliates or any other direct or indirect owner of Oncor or Oncor Holdings, and vice versa. Accordingly, our operations are conducted, and our cash flows are managed, independently from Sempra and its affiliates and any other direct or indirect owner of Oncor or Oncor Holdings. Oncor is a limited liability company governed by a board of directors, not its members. The Sempra Order and our Limited Liability Company Agreement require that the board of directors of Oncor consist of thirteen members, constituted as follows: seven Disinterested Directors, who (i) shall be independent directors in all material respects under the rules of the New York Stock Exchange in relation to Sempra or its subsidiaries and affiliated entities and any entity with a direct or indirect ownership interest in Oncor or Oncor Holdings, and (ii) shall have no material relationship with Sempra or its subsidiaries or affiliated entities or any entity with a direct or indirect ownership interest in Oncor or Oncor Holdings, currently or within the previous ten years ; two members designated by Sempra (through Oncor Holdings); two members designated by Texas Transmission; and two current or former officers of Oncor (each, an Oncor Officer Director), currently Robert S. Shapard and E. Allen Nye, Jr., who are our Chairman of our board of directors and Chief Executive, respectively. Until March 9, 2028, in order for a current or former officer of Oncor to be eligible to serve as an Oncor Officer Director, the officer cannot have worked for Sempra or any of its affiliates (excluding Oncor Holdings and Oncor) or any other entity with a direct or indirect ownership interest in Oncor or Oncor Holdings in the ten-year period prior to the date on which the officer first became employed by Oncor. Oncor Holdings, at the direction of STIH, has the right to nominate and/or seek the removal of the Oncor Officer Directors, subject to approval by a majority of the Oncor board of directors. In addition, the Sempra Order provides that Oncor’s board of directors cannot be overruled by the board of directors of Sempra or any of its subsidiaries on dividend policy, the issuance of dividends or other distributions (except for contractual tax payments), debt issuance, capital expenditures, operation and maintenance expenditures, management and service fees, and appointment or removal of members of the board of directors, provided that certain actions may also require the additional approval of the Oncor Holdings board of directors. The Sempra Order also provides that any changes to the size, composition, structure or rights of the board of directors must first be approved by the PUCT. In addition, if Sempra acquires Texas Transmission’s interest in Oncor, the two board of director positions on Oncor’s board of directors that Texas Transmission is entitled to appoint will be eliminated and the size of Oncor’s board of directors will be reduced by two. Additional regulatory commitments, governance mechanisms and restrictions provided in the Sempra Order and our Limited Liability Company Agreement to ring-fence Oncor from its owners include, among others: A majority of the Disinterested Directors of Oncor and the directors designated by Texas Transmission that are present and voting (of which at least one must be present and voting) must approve any annual or multi-year budget if the aggregate amount of capital expenditures or operating and maintenance expenditures in such budget is more than a 10 % increase or decrease from the corresponding amounts of such expenditures in the budget for the preceding fiscal year or multi-year period, as applicable; Oncor may not pay any dividends or make any other distributions (except for contractual tax payments) if a majority of its Disinterested Directors or either of the two directors appointed by Texas Transmission determines that it is in the best interests of Oncor to retain such amounts to meet expected future requirements; At all times, Oncor will remain in compliance with the debt-to-equity ratio established by the PUCT from time to time for ratemaking purposes, and Oncor will not pay dividends or other distributions (except for contractual tax payments), if that payment would cause its debt-to-equity ratio to exceed the debt-to-equity ratio approved by the PUCT; If the credit rating on Oncor’s senior secured debt by any of the three major rating agencies falls below BBB (or the equivalent), Oncor will suspend dividends and other distributions (except for contractual tax payments), unless otherwise allowed by the PUCT; Without the prior approval of the PUCT, neither Sempra nor any of its affiliates (excluding Oncor) will incur, guaranty or pledge assets in respect of any indebtedness that is dependent on the revenues of Oncor in more than a proportionate degree than the other revenues of Sempra or on the membership interests of Oncor, and there will be no debt at STH or STIH at any time following Sempra’s acquisition of Oncor Holdings; Neither Oncor nor Oncor Holdings will lend money to, borrow money from or share credit facilities with Sempra or any of its affiliates (other than Oncor subsidiaries), or any entity with a direct or indirect ownership interest in Oncor or Oncor Holdings; There must be maintained certain “separateness measures” that reinforce the legal and financial separation of Oncor from its owners, including a requirement that dealings between Oncor, Oncor Holdings and their subsidiaries with Sempra, any of Sempra’s other affiliates or any entity with a direct or indirect ownership interest in Oncor or Oncor Holdings, must be on an arm’s-length basis, limitations on affiliate transactions, separate recordkeeping requirements and a prohibition on Sempra or its affiliates or any entity with a direct or indirect ownership interest in Oncor or Oncor Holdings pledging Oncor assets or membership interests for any entity other than Oncor; and Sempra will continue to hold indirectly at least 51 % of the ownership interests in Oncor and Oncor Holdings for at least five years following the Sempra Acquisition, unless otherwise specifically authorized by the PUCT. Basis of Presentation These unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and related notes included in our 2021 Form 10-K. In the opinion of Oncor management, all adjustments (consisting of normal recurring accruals) necessary for a fair presentation of the results of operations and financial position have been made. We have evaluated all subsequent events through the date the financial statements were issued. All appropriate intercompany items and transactions have been eliminated in consolidation. The results of operations for an interim period may not give a true indication of results for a full year due to seasonality. Our consolidated financial statements have been prepared in accordance with GAAP governing rate-regulated operations. All dollar amounts in the financial statements and tables in the notes are stated in millions of U.S. dollars unless otherwise indicated. Use of Estimates Preparation of our financial statements requires management to make estimates and assumptions about future events that affect the reporting of assets and liabilities at the balance sheet dates and the reported amounts of revenue and expense, including fair value measurements. In the event estimates and/or assumptions prove to be different from actual amounts, adjustments are made in subsequent periods to reflect more current information. No material adjustments were made to previous estimates or assumptions during the current period. Interest Rate Derivatives and Hedge Accounting We are exposed to interest rates primarily as a result of our current and expected use of financing. We may, from time to time, utilize interest rate derivative instruments typically designated as cash flow hedges, to lock in interest rates in anticipation of future financings. We may designate an interest rate derivative instrument as a cash flow hedge if it effectively converts anticipated cash flows associated with interest payments to a fixed dollar amount. In accounting for cash flow hedges, derivative assets and liabilities are recorded on the balance sheet at fair value with an offset to other comprehensive income. Amounts remain in accumulated other comprehensive income and are reclassified into net income as the interest expense on the related debt affects net income. Impairment of Long-Lived Assets and Goodwill We evaluate long-lived assets (including intangible assets with finite lives) for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. We also evaluate goodwill for impairment annually on October 1 and whenever events or changes in circumstances indicate that an impairment may exist. The determination of the existence of these and other indications of impairment involves judgments that are subjective in nature and may require the use of estimates in forecasting future results and cash flows. Cash, Cash Equivalents and Restricted Cash For purposes of reporting cash and cash equivalents, highly liquid investments with original maturities of three months or less at the date of purchase are considered to be cash equivalents. The following table provides a reconciliation of cash, cash equivalents and restricted cash reported on the Condensed Consolidated Balance Sheets to the sum of such amounts reported on the Condensed Statements of Consolidated Cash Flows: At March 31, At December 31, 2022 2021 Cash, cash equivalents and restricted cash Cash and cash equivalents $ 104 $ 11 Restricted cash, current (a) 35 13 Restricted cash, noncurrent (a) 66 30 Total cash, cash equivalents and restricted cash on the Condensed Statements of Consolidated Cash Flows $ 205 $ 54 ____________ (a) Restricted cash represents amounts deposited with Oncor by our customers that are subject to return in accordance with the PUCT rules, ERCOT requirements or our tariffs, relating to generation interconnection and construction and/or extension of electric delivery system facilities. We maintain these amounts in a separate escrow account. Contingencies Our financial results may be affected by judgments and estimates related to contingencies. For loss contingencies, we accrue the loss if an event has occurred on or before the balance sheet date, and: information available through the date we file our financial statements indicates it is probable that a loss has been incurred, given the likelihood of uncertain future events; and the amount of the loss can be reasonably estimated. We do not accrue contingencies that might result in gains. We continuously assess contingencies for litigation claims, environmental remediation and other events. See Note 6 for a discussion of contingencies. Effects of Reference Rate Reform on Financial Reporting Our Credit Facility uses LIBOR as a benchmark for establishing interest rates but incorporates a transition mechanism for the phase-out of LIBOR. In the event we modify our Credit Facility related to the phase-out of LIBOR, we will evaluate the optional expedients and exceptions under ASU No. 2020-04. The standard allows entities to account for contract modifications as an event that does not require reassessment or remeasurement (i.e., as a continuation of the existing contract). |

REGULATORY MATTERS | 2. REGULATORY MATTERS Regulatory Assets and Liabilities Recognition of regulatory assets and liabilities and the periods over which they are to be recovered or refunded through rate regulation reflect the decisions of the PUCT. Components of our regulatory assets and liabilities and their remaining recovery periods as of March 31, 2022 are provided in the table below. Amounts not currently earning a return through rate regulation are noted. Remaining Rate Recovery/Amortization Period At March 31, 2022 At March 31, 2022 At December 31, 2021 Regulatory assets: Employee retirement liability (a)(b)(c) To be determined $ 323 $ 328 Employee retirement costs being amortized 6 years 183 193 Employee retirement costs incurred since the last rate review period (b) To be determined 97 99 Self-insurance reserve (primarily storm recovery costs) being amortized 6 years 213 223 Self-insurance reserve incurred since the last rate review period (primarily storm related) (b) To be determined 429 373 Debt reacquisition costs Lives of related debt 18 19 Under-recovered AMS costs 6 years 123 128 Energy efficiency performance bonus (a) 1 year or less 23 31 Wholesale distribution substation service To be determined 81 75 Unrecovered expenses related to COVID-19 To be determined 35 35 Recoverable deferred income taxes - net Various 17 16 Uncollectible payments from REPs (b) To be determined 9 9 Other regulatory assets Various 20 18 Total regulatory assets 1,571 1,547 Regulatory liabilities: Estimated net removal costs Lives of related assets 1,370 1,348 Excess deferred taxes Primarily over lives of related assets 1,425 1,442 Over-recovered wholesale transmission service expense (a) 1 year or less 6 7 Unamortized gain on reacquisition of debt Lives of related debt 26 26 Employee retirement costs over-recovered since last rate review period (b) To be determined 45 39 Other regulatory liabilities Various 20 14 Total regulatory liabilities 2,892 2,876 Net regulatory assets (liabilities) $ ( 1,321 ) $ ( 1,329 ) ____________ (a) Not earning a return in the regulatory rate-setting process. (b) Recovery/refund is specifically authorized by statute or by the PUCT, subject to reasonableness review. (c) Represents unfunded liabilities recorded in accordance with pension and OPEB accounting standards. Base Rate Review Filing Deadline (PUCT Docket No. 52100) On May 10, 2021, we filed an application with the PUCT requesting to extend our base rate review filing deadline from October 1, 2021 to June 1, 2022. On July 29, 2021, the PUCT approved an order granting the extension. As a result, our next base rate review must be filed on or before June 1, 2022. PUCT Project No. 50664, Issues Related to the State of Disaster for the Coronavirus Disease 2019 In March 2020, the PUCT issued an order in PUCT Project No. 50664, Issues Related to the State of Disaster for the Coronavirus Disease 2019 , authorizing transmission and distribution utilities to use a regulatory asset accounting mechanism and a subsequent process to seek future recovery of expenses resulting from the effects of the COVID-19 pandemic. Since then, we have been recording incremental costs incurred by Oncor resulting from the effects of the COVID-19 pandemic, including costs relating to the implementation of our pandemic r eadiness plan, as a regulatory asset. At March 31, 2022, the balance of this regulatory asset was $ 35 million. |
Revenues

Revenues [Abstract] | |
REVENUES | 3. REVENUES General Our revenue is billed monthly under tariffs approved by the PUCT and the majority of revenues are related to providing electric delivery service to consumers. Tariff rates are designed to recover the cost of providing electric delivery service to customers including a reasonable rate of return on invested capital. As the volumes delivered can be directly measured, our revenues are recognized when the underlying service has been provided in an amount prescribed by the related tariff. We recognize revenue in the amount that we have the right to invoice. Substantially all of our revenues are from contracts with customers except for alternative revenue program revenues discussed below. Reconcilable Tariffs The PUCT has designated certain tariffs (primarily TCRF and EECRF) as reconcilable, which means the differences between amounts billed under these tariffs and the related incurred costs are deferred as either regulatory assets or regulatory liabilities. Accordingly, at prescribed intervals, future tariffs are adjusted to either repay regulatory liabilities or collect regulatory assets. Alternative Revenue Program The PUCT has implemented an incentive program allowing us to earn energy efficiency program performance bonuses by exceeding PUCT-approved energy efficiency program targets. This incentive program and the related performance bonus revenues are considered an “alternative revenue program” under GAAP. Annual performance bonuses are recognized as revenue when approved by the PUCT, typically in the third or fourth quarter each year. Disaggregation of Revenues The following table reflects electric delivery revenues disaggregated by tariff: Three Months Ended March 31, 2022 2021 Operating revenues Revenues contributing to earnings: Distribution base revenues $ 578 $ 540 Transmission base revenues (TCOS revenues): Billed to third-party wholesale customers 233 208 Billed to REPs serving Oncor distribution customers, through TCRF 130 114 Total transmission base revenues 363 322 Other miscellaneous revenues 18 17 Total revenues contributing to earnings 959 879 Revenues collected for pass-through expenses: TCRF – third-party wholesale transmission service 281 249 EECRF 9 11 Total revenues collected for pass-through expenses 290 260 Total operating revenues $ 1,249 $ 1,139 Customers Our distribution business customers consist of REPs (approximately 95 at March 31, 2022) and certain electric cooperatives in our certificated service area. The consumers of the electricity we deliver are free to choose their electricity supplier from REPs who compete for their business. Our transmission base revenues are collected from load serving entities benefiting from our transmission system. Our transmission business customers consist of other distribution companies, municipalities and electric cooperatives. REP subsidiaries of our two largest customers collectively represented 26 % and 24 % of our total operating revenues for the three months ended March 31, 2022. No other customer represented more than 10% of our total operating revenues for the three months ended March 31, 2022. Variability Our revenues and cash flows are subject to seasonality, timing of customer billings, weather conditions and other electricity usage drivers, with revenues being highest in the summer. Payment of customer billings is due 35 days after invoicing. Under a PUCT rule relating to the Certification of Retail Electric Providers, write-offs of uncollectible amounts owed by REPs are recoverable as a regulatory asset. Pass-through Expenses Revenue equal to expenses that are allowed to be passed-through to customers (primarily third-party wholesale transmission service and energy efficiency program costs) are recognized at the time the expense is recognized. Franchise taxes are assessed by local governmental bodies, based on kWh delivered and are not a “pass-through” item. The rates we charge customers are intended to recover the franchise taxes, but we are not acting as an agent to collect the taxes from customers; therefore, franchise taxes are reported as a principal component of “taxes other than amounts related to income taxes” instead of a reduction to “revenues” in the income statement. |

Short-Term Borrowings [Abstract] | |
SHORT-TERM BORROWINGS | 4. SHORT-TERM BORROWINGS At March 31, 2022 and December 31, 2021, outstanding short-term borrowings under our Credit Facility and CP Program consisted of the following: At March 31, At December 31, 2022 2021 Total credit facility borrowing capacity $ 2,000 $ 2,000 Credit facility outstanding borrowings - - Commercial paper outstanding (a) - ( 215 ) Letters of credit outstanding (b) - ( 8 ) Available unused credit $ 2,000 $ 1,777 ____________ (a) The weighted average interest rate on commercial paper was 0.30 % at December 31, 2021. (b) The interest rate on outstanding letters of credit was 1.20 % at December 31, 2021, based on our credit ratings. Credit Facility In November 2021, we entered into a $ 2.0 billion unsecured revolving Credit Facility that includes sustainability-linked pricing metrics related to specific environmental and employee health and safety sustainability objectives. The Credit Facility may be used for working capital and general corporate purposes, issuances of letters of credit and to support our CP Program. The Credit Facility has a maturity date of November 9, 2026. We also have the option of requesting up to two 1 -year extensions and an option to request an increase in our borrowing capacity of up to $ 400 million in $ 100 million minimum increments, provided certain conditions set forth in the Credit Facility are met, including lender approvals. CP Program In March 2018, we established the CP Program, under which we may issue unsecured CP Notes on a private placement basis up to a maximum aggregate face or principal amount outstanding at any time of $ 2.0 billion. The proceeds of CP Notes issued under the CP Program are used for working capital and general corporate purposes. The CP Program obtains liquidity support from our Credit Facility discussed above. We may utilize either the CP Program or the Credit Facility, at our option, to meet our funding needs. |

Long-Term Debt [Abstract] | |
LONG-TERM DEBT | 5. LONG-TERM DEBT Our long-term debt includes fixed rate secured and variable rate unsecured debt. Our secured debt is secured equally and ratably by a first priority lien on certain transmission and distribution assets. See “Deed of Trust” below for additional information. At March 31, 2022 and December 31, 2021, our long-term debt consisted of the following: At March 31, At December 31, 2022 2021 Fixed Rate Secured: 4.10 % Senior Notes due June 1, 2022 (a) $ - $ 400 7.00 % Debentures due September 1, 2022 482 482 2.75 % Senior Notes due June 1, 2024 500 500 2.95 % Senior Notes due April 1, 2025 350 350 0.55 % Senior Notes due October 1, 2025 450 450 3.86 % Senior Notes Series A, due December 3, 2025 174 174 3.86 % Senior Notes Series B, due January 14, 2026 38 38 3.70 % Senior Notes due November 15, 2028 650 650 5.75 % Senior Notes due March 15, 2029 318 318 2.75 % Senior Notes due May 15, 2030 700 700 7.00 % Senior Notes due May 1, 2032 494 494 7.25 % Senior Notes due January 15, 2033 323 323 7.50 % Senior Notes due September 1, 2038 300 300 5.25 % Senior Notes due September 30, 2040 475 475 4.55 % Senior Notes due December 1, 2041 400 400 5.30 % Senior Notes due June 1, 2042 348 348 3.75 % Senior Notes due April 1, 2045 550 550 3.80 % Senior Notes due September 30, 2047 325 325 4.10 % Senior Notes due November 15, 2048 450 450 3.80 % Senior Notes due June 1, 2049 500 500 3.10 % Senior Notes due September 15, 2049 700 700 3.70 % Senior Notes due May 15, 2050 400 400 2.70 % Senior Notes due November 15, 2051 500 500 5.35 % Senior Notes due October 1, 2052 300 300 Fixed rate secured long-term debt 9,727 10,127 Variable Rate Unsecured: Term loan credit agreement maturing April 29, 2023 1,185 - Variable rate unsecured long-term debt 1,185 - Total long-term debt 10,912 10,127 Unamortized discount and debt issuance costs ( 93 ) ( 95 ) Less amount due currently ( 482 ) ( 882 ) Long-term debt, less amounts due currently $ 10,337 $ 9,150 ____________ (a) In March 2022, we redeemed in full the $ 400 million aggregate principal amount of the notes that were to mature on June 1, 2022. See “2022 Notes Redemption” below for more information. Long-Term Debt-Related Activity in 2022 January 2022 Term Loan Credit Agreement On January 28, 2022, we entered into an unsecured term loan credit agreement with a commitment equal to an aggregate principal amount of $ 1.30 billion (January 2022 Term Loan Credit Agreement). The January 2022 Term Loan Credit Agreement matures on April 29, 2023. The January 2022 Term Loan Credit Agreement provides that we can borrow up to the full amount in up to four borrowings, at our option, at any time before April 28, 2022. Under the January 2022 Term Loan Credit Agreement, we borrowed $ 400 million on January 28, 2022 , $ 600 million on February 28, 2022 (the February 2022 borrowing), $ 185 million on March 28, 2022, and $ 115 million on April 28, 2022 (the April 2022 borrowing). At March 31, 2022, aggregate borrowings under the January 2022 Term Loan Credit Agreement totaled $ 1.185 billion. Following the April 2022 borrowing, no remaining borrowings are available under the January 2022 Term Loan Credit Agreement. The proceeds from each borrowing were used for general corporate purposes, including to repay outstanding CP Notes and, in the case of the February 2022 borrowing, to redeem $ 400 million aggregate principal amount outstanding of our 4.10 % Senior Secured Notes due June 1, 2022 (2022 notes), plus accrued and unpaid interest on the 2022 notes. Loans under the January 2022 Term Loan Credit Agreement bear interest , at our option, at either (i) an adjusted term SOFR (calculated based on one-month term SOFR as of a specified date, plus an adjustment of 0.10 % (SOFR Adjustment)) plus a spread of 0.575 %, (ii) an adjusted daily simple SOFR (calculated based on daily simple SOFR as of a specified date, plus the SOFR Adjustment) plus a spread of 0.575 %, or (iii) for any day, at a rate equal to the greatest of: (1) the prime rate publicly announced by the administrative agent on such date, (2) the federal funds effective rate on such date plus 0.50 %, and (3) daily simple SOFR on such date, plus 1.0 %. 2022 Notes Redemption O n March 1, 2022, we redeemed in full the $ 400 million aggregate principal amount of 2022 notes that were outstanding, which were to mature on June 1, 2022. The redemption price was equal to 100 % of the principal amount of the 2022 notes, plus accrued interest to, but not including, the redemption date of March 1, 2022. Following the redemption of the 2022 notes, none of the 2022 notes remained outstanding. Deed of Trust Our secured debt is secured equally and ratably by a first priority lien on all property acquired or constructed by Oncor for use in its electricity transmission and distribution business, subject to certain exceptions. The property is mortgaged under the Deed of Trust. The Deed of Trust permits us to secure indebtedness with the lien of the Deed of Trust up to the aggregate of (i) the amount of available bond credits, and (ii) 85 % of the lower of the fair value or cost of certain property additions that could be certified to the Deed of Trust collateral agent. At March 31, 2022, the amount of available bond credits was $ 2.112 billion and the amount of future debt we could secure with property additions, subject to those property additions being certified to the Deed of Trust collateral agent, was $ 5.110 billion. Borrowings under the CP Program, the Credit Facility and January 2022 Term Loan Credit Agreement are not secured. Fair Value of Long-Term Debt At March 31, 2022 and December 31, 2021, the estimated fair value of our long-term debt (including current maturities) totaled $ 11.476 billion and $ 11.758 billion, respectively, and the carrying amount totaled $ 10.819 billion and $ 10.032 billion, respectively. The fair value is estimated using observable market data, representing Level 2 valuations under accounting standards related to the determination of fair value. |

Commitments And Contingencies [Abstract] | |
COMMITMENTS AND CONTINGENCIES | 6. COMMITMENTS AND CONTINGENCIES Legal/Regulatory Proceedings We are involved in various legal and administrative proceedings in the normal course of business, the ultimate resolution of which, in the opinion of management, should not have a material effect upon our financial position, results of operations, or cash flows. See Note 2 above and Note 7 to Financial Statements in our 2021 Form 10-K for additional information regarding our regulatory and legal proceedings, respectively. Leases As lessee, our leased assets primarily consist of our vehicle fleet and real estate leased for company offices and service centers. Our leases are accounted for as operating leases for GAAP purposes. At March 31, 2022, we had $ 5 million in GAAP operating leases that are treated as capital leases solely for rate-making purposes. We generally recognize operating lease costs on a straight-line basis over the lease term in operating expenses. We are not a lessor to any material lease contracts. See Note 7 to Financial Statements in our 2021 Form 10-K for additional information on leases. Sales and Use Tax Audits We are subject to sales and use tax audits in the normal course of business. Currently, the Texas State Comptroller’s office is conducting sales and use tax audits for audit periods 2010 through June 2013, July 2013 through 2017, and 2018 through 2021. No audit reports have been issued for these audits. While the outcome is uncertain, based on our analysis, the ultimate resolution of these audits should not have a material adverse effect on our financial position, results of operations, or cash flows. |

Membership Interests [Abstract] | |
MEMBERSHIP INTERESTS | 7. MEMBERSHIP INTERESTS Contributions We received cash capital contributions from our members on February 17, 2022 and April 26, 2022 each totaling $ 106 million. Distributions The Sempra Order and our Limited Liability Company Agreement set forth various restrictions on distributions to our members. Among those restrictions is the commitment that we will make no distributions (other than contractual tax payments) to our members that would cause us to exceed the PUCT’s authorized debt-to-equity ratio. Our current authorized regulatory capital structure is 57.5 % debt to 42.5 % equity. The distribution restrictions also include the ability of a majority of our Disinterested Directors, or either of the two member directors designated by Texas Transmission, to limit distributions to the extent each determines it is necessary to meet expected future requirements of Oncor (including continuing compliance with the PUCT debt-to-equity ratio commitment). At March 31, 2022, our regulatory capitalization was 54.4 % debt to 45.6 % equity and as a result we had $ 1.074 billion available to distribute to our members. The PUCT has the authority to determine what types of debt and equity are included in a utility’s debt-to-equity ratio. For purposes of this ratio, debt is calculated as long-term debt including any finance leases plus unamortized gains on reacquired debt less unamortized issuance expenses, premiums and losses on reacquired debt. Equity is calculated as membership interests determined in accordance with GAAP, excluding accumulated other comprehensive loss and the effects of acquisition accounting from a 2007 transaction. On February 18, 2022, our board of directors declared a cash distribution of $ 106 million, which was paid to our members on February 18, 2022. On April 27, 2022, our board of directors declared a cash distribution of $ 106 million, which was paid to our members on April 28, 2022.

Pension And OPEB Plans [Abstract] | |
PENSION AND OPEB PLANS | 8. PENSION AND OPEB PLANS Pension Plans We sponsor the Oncor Retirement Plan and also have liabilities related to the Vistra Retirement Plan, both of which are qualified pension plans under Section 401(a) of the Internal Revenue Code of 1986, as amended, and are subject to the provisions of ERISA. Employees do not contribute to either plan. We also have a supplemental retirement plan for certain employees whose retirement benefits cannot be fully earned under the qualified retirement plans. See Note 9 to Financial Statements in our 2021 Form 10-K for additional information regarding pension plans. OPEB Plans We currently sponsor two OPEB plans. One plan covers our eligible current and future retirees whose services are 100 % attributed to the regulated business. The second plan covers retirees and eligible current and future retirees whose employment services were assigned to both Oncor (or a predecessor regulated utility business) and the non-regulated business of formerly affiliated companies including Vistra. Vistra is solely responsible for its portion of the liability for retiree benefits related to those retirees. See Note 9 to Financial Statements in our 2021 Form 10-K for additional information. Pension and OPEB Costs Our net costs related to pension plans and the OPEB Plans for the three months ended March 31, 2022 and 2021, were comprised of the following: Three Months Ended March 31, 2022 2021 Components of net allocated pension costs: Service cost $ 8 $ 9 Interest cost 22 21 Expected return on assets ( 26 ) ( 25 ) Amortization of net loss 8 13 Net pension costs 12 18 Components of net OPEB costs: Service cost 1 1 Interest cost 6 6 Expected return on assets ( 2 ) ( 1 ) Amortization of prior service cost - ( 4 ) Amortization of net loss - 4 Net OPEB costs 5 6 Total net pension and OPEB costs 17 24 Less amounts deferred principally as property, regulatory asset or regulatory liability 1 ( 5 ) Net amounts recognized as operation and maintenance expense or other deductions $ 18 $ 19 The discount rates reflected in net pension and OPEB costs in 2022 are 2.91 %, 2.94 % and 2.47 % for the Oncor Retirement Plan, the Vistra Retirement Plan and the OPEB Plans, respectively. The expected return on pension and OPEB plan assets reflected in the 2022 cost amounts are 4.87 %, 4.66 % and 5.61 % for the Oncor Retirement Plan, the Vistra Retirement Plan and the OPEB Plans, respectively. Pension Plans and OPEB Plans Cash Contributions We made cash contributions to the pension plans and OPEB Plans of $ 1 million and $ 9 million, respectively, during the three months ended March 31, 2022. We expect to make additional cash contributions to the pension plans and OPEB Plans of $ 4 million and $ 26 million, respectively, during the remainder of 2022. Our pension plans and OPEB Plans funding is expected to total approximately $ 90 million and $ 177 million, respectively, in the five-year period from 2022 to 2026 based on the latest actuarial projections. |

Related-Party Transactions [Abstract] | |
RELATED-PARTY TRANSACTIONS | 9. RELATED-PARTY TRANSACTIONS The following represent our significant related-party transactions. We are not a member of another entity’s consolidated tax group, but our owners’ federal income tax returns include their portion of our results. Under the terms of a tax sharing agreement among us, Oncor Holdings, Texas Transmission and STH, we are generally obligated to make payments to our owners, pro rata in accordance with their respective membership interests, in an aggregate amount that is substantially equal to the amount of federal income taxes that we would have been required to pay if we were filing our own corporate income tax return. STH will file a combined Texas margin tax return that includes our results and our share of Texas margin tax payments, which are accounted for as income taxes and calculated as if we were filing our own return. See discussion in Note 1 to Financial Statements in our 2021 Form 10-K under “Provision in Lieu of Income Taxes.” Under the “in lieu of” tax concept, all in lieu of tax assets and tax liabilities represent amounts that will eventually be settled with our members. In the event such amounts are not paid under the tax sharing agreement, it is probable that these regulatory amounts will continue to be included in Oncor’s rate setting processes. Amounts payable to (receivable from) members related to income taxes under the tax sharing agreement and reported on our balance sheets consisted of the following: At March 31, 2022 At December 31, 2021 STH Texas Transmission Total STH Texas Transmission Total Federal income taxes payable (receivable) $ 10 $ 3 $ 13 $ ( 5 ) $ ( 1 ) $ ( 6 ) Texas margin tax payable 30 - 30 24 - 24 Net payable (receivable) $ 40 $ 3 $ 43 $ 19 $ ( 1 ) $ 18 There were no cash payments made to (received from) members related to income taxes for the three months ended March 31, 2022 and 2021. See Note 7 for information regarding cash capital contributions from and distributions to members. Sempra owns an indirect 50 percent interest in the parent of Sharyland. Sharyland provided wholesale transmission service to us in the amount of $ 2 million and $ 3 million in the three months ended March 31, 2022 and 2021, respectively, at rates set pursuant to PUCT-approved tariffs. Pursuant to an operation agreement between us and Sharyland that was entered into in connection with a PUCT order, we provide Sharyland with substation monitoring and switching services. These services totaled less than $ 1 million in each of the three months ended March 31, 2022 and 2021. |

Description Of Business | Description of Business References in this report to “we,” “our,” “us” and “the company” are to Oncor and/or its subsidiaries as apparent in the context. See “Glossary” for the definition of terms and abbreviations. We are a regulated electricity transmission and distribution company that provides the essential service of delivering electricity safely, reliably and economically to end-use consumers through our electrical systems, as well as providing transmission grid connections to merchant generation facilities and interconnections to other transmission grids in Texas. Our transmission and distribution rates are regulated by the PUCT and certain cities, and in certain limited instances, by the FERC. We are not a seller of electricity, nor do we purchase electricity for resale. We are a direct, majority-owned subsidiary of Oncor Holdings, which is indirectly and wholly owned by Sempra. Oncor Holdings owns 80.25 % of our outstanding membership interests and Texas Transmission owns 19.75 % of our outstanding membership interests. We are managed as an integrated business; consequently, there is only one reportable segment. |
Ring-Fencing Measures | Ring-Fencing Measures Since 2007, various ring-fencing measures have been taken to enhance our credit quality and the separateness between the Oncor Ring-Fenced Entities and entities with ownership interests in Oncor or Oncor Holdings. These ring-fencing measures serve to mitigate the Oncor Ring-Fenced Entities’ credit exposure to owners of Oncor and Oncor Holdings, and to reduce the risk that the assets and liabilities of the Oncor Ring-Fenced Entities would be substantively consolidated with the assets and liabilities of any direct or indirect owners of Oncor and Oncor Holdings in connection with a bankruptcy of any such entities. These measures include the November 2008 sale of 19.75 % of Oncor’s equity interests to Texas Transmission. In March 2018, Sempra indirectly acquired Oncor Holdings after obtaining various approvals, including PUCT approval through the Sempra Order, which outlines certain ring-fencing measures, governance mechanisms and restrictions that apply after the Sempra Acquisition. As a result of these ring-fencing measures, Sempra does not control Oncor, and the ring-fencing measures limit Sempra’s ability to direct the management, policies and operations of Oncor, including the deployment or disposition of Oncor’s assets, declarations of dividends, strategic planning and other important corporate issues and actions. None of the assets of the Oncor Ring-Fenced Entities are available to satisfy the debt or obligations of any Sempra entity or any other direct or indirect owner of Oncor or Oncor Holdings. The assets and liabilities of the Oncor Ring-Fenced Entities are separate and distinct from those of any Sempra entities and any other direct or indirect owner of Oncor or Oncor Holdings. We do not bear any liability for debt or contractual obligations of Sempra and its affiliates or any other direct or indirect owner of Oncor or Oncor Holdings, and vice versa. Accordingly, our operations are conducted, and our cash flows are managed, independently from Sempra and its affiliates and any other direct or indirect owner of Oncor or Oncor Holdings. Oncor is a limited liability company governed by a board of directors, not its members. The Sempra Order and our Limited Liability Company Agreement require that the board of directors of Oncor consist of thirteen members, constituted as follows: seven Disinterested Directors, who (i) shall be independent directors in all material respects under the rules of the New York Stock Exchange in relation to Sempra or its subsidiaries and affiliated entities and any entity with a direct or indirect ownership interest in Oncor or Oncor Holdings, and (ii) shall have no material relationship with Sempra or its subsidiaries or affiliated entities or any entity with a direct or indirect ownership interest in Oncor or Oncor Holdings, currently or within the previous ten years ; two members designated by Sempra (through Oncor Holdings); two members designated by Texas Transmission; and two current or former officers of Oncor (each, an Oncor Officer Director), currently Robert S. Shapard and E. Allen Nye, Jr., who are our Chairman of our board of directors and Chief Executive, respectively. Until March 9, 2028, in order for a current or former officer of Oncor to be eligible to serve as an Oncor Officer Director, the officer cannot have worked for Sempra or any of its affiliates (excluding Oncor Holdings and Oncor) or any other entity with a direct or indirect ownership interest in Oncor or Oncor Holdings in the ten-year period prior to the date on which the officer first became employed by Oncor. Oncor Holdings, at the direction of STIH, has the right to nominate and/or seek the removal of the Oncor Officer Directors, subject to approval by a majority of the Oncor board of directors. In addition, the Sempra Order provides that Oncor’s board of directors cannot be overruled by the board of directors of Sempra or any of its subsidiaries on dividend policy, the issuance of dividends or other distributions (except for contractual tax payments), debt issuance, capital expenditures, operation and maintenance expenditures, management and service fees, and appointment or removal of members of the board of directors, provided that certain actions may also require the additional approval of the Oncor Holdings board of directors. The Sempra Order also provides that any changes to the size, composition, structure or rights of the board of directors must first be approved by the PUCT. In addition, if Sempra acquires Texas Transmission’s interest in Oncor, the two board of director positions on Oncor’s board of directors that Texas Transmission is entitled to appoint will be eliminated and the size of Oncor’s board of directors will be reduced by two. Additional regulatory commitments, governance mechanisms and restrictions provided in the Sempra Order and our Limited Liability Company Agreement to ring-fence Oncor from its owners include, among others: A majority of the Disinterested Directors of Oncor and the directors designated by Texas Transmission that are present and voting (of which at least one must be present and voting) must approve any annual or multi-year budget if the aggregate amount of capital expenditures or operating and maintenance expenditures in such budget is more than a 10 % increase or decrease from the corresponding amounts of such expenditures in the budget for the preceding fiscal year or multi-year period, as applicable; Oncor may not pay any dividends or make any other distributions (except for contractual tax payments) if a majority of its Disinterested Directors or either of the two directors appointed by Texas Transmission determines that it is in the best interests of Oncor to retain such amounts to meet expected future requirements; At all times, Oncor will remain in compliance with the debt-to-equity ratio established by the PUCT from time to time for ratemaking purposes, and Oncor will not pay dividends or other distributions (except for contractual tax payments), if that payment would cause its debt-to-equity ratio to exceed the debt-to-equity ratio approved by the PUCT; If the credit rating on Oncor’s senior secured debt by any of the three major rating agencies falls below BBB (or the equivalent), Oncor will suspend dividends and other distributions (except for contractual tax payments), unless otherwise allowed by the PUCT; Without the prior approval of the PUCT, neither Sempra nor any of its affiliates (excluding Oncor) will incur, guaranty or pledge assets in respect of any indebtedness that is dependent on the revenues of Oncor in more than a proportionate degree than the other revenues of Sempra or on the membership interests of Oncor, and there will be no debt at STH or STIH at any time following Sempra’s acquisition of Oncor Holdings; Neither Oncor nor Oncor Holdings will lend money to, borrow money from or share credit facilities with Sempra or any of its affiliates (other than Oncor subsidiaries), or any entity with a direct or indirect ownership interest in Oncor or Oncor Holdings; There must be maintained certain “separateness measures” that reinforce the legal and financial separation of Oncor from its owners, including a requirement that dealings between Oncor, Oncor Holdings and their subsidiaries with Sempra, any of Sempra’s other affiliates or any entity with a direct or indirect ownership interest in Oncor or Oncor Holdings, must be on an arm’s-length basis, limitations on affiliate transactions, separate recordkeeping requirements and a prohibition on Sempra or its affiliates or any entity with a direct or indirect ownership interest in Oncor or Oncor Holdings pledging Oncor assets or membership interests for any entity other than Oncor; and Sempra will continue to hold indirectly at least 51 % of the ownership interests in Oncor and Oncor Holdings for at least five years following the Sempra Acquisition, unless otherwise specifically authorized by the PUCT. |
Basis Of Presentation | Basis of Presentation These unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and related notes included in our 2021 Form 10-K. In the opinion of Oncor management, all adjustments (consisting of normal recurring accruals) necessary for a fair presentation of the results of operations and financial position have been made. We have evaluated all subsequent events through the date the financial statements were issued. All appropriate intercompany items and transactions have been eliminated in consolidation. The results of operations for an interim period may not give a true indication of results for a full year due to seasonality. Our consolidated financial statements have been prepared in accordance with GAAP governing rate-regulated operations. All dollar amounts in the financial statements and tables in the notes are stated in millions of U.S. dollars unless otherwise indicated. |
Use Of Estimates | Use of Estimates Preparation of our financial statements requires management to make estimates and assumptions about future events that affect the reporting of assets and liabilities at the balance sheet dates and the reported amounts of revenue and expense, including fair value measurements. In the event estimates and/or assumptions prove to be different from actual amounts, adjustments are made in subsequent periods to reflect more current information. No material adjustments were made to previous estimates or assumptions during the current period. |
Interest Rate Derivatives And Hedge Accounting | Interest Rate Derivatives and Hedge Accounting We are exposed to interest rates primarily as a result of our current and expected use of financing. We may, from time to time, utilize interest rate derivative instruments typically designated as cash flow hedges, to lock in interest rates in anticipation of future financings. We may designate an interest rate derivative instrument as a cash flow hedge if it effectively converts anticipated cash flows associated with interest payments to a fixed dollar amount. In accounting for cash flow hedges, derivative assets and liabilities are recorded on the balance sheet at fair value with an offset to other comprehensive income. Amounts remain in accumulated other comprehensive income and are reclassified into net income as the interest expense on the related debt affects net income. |
Impairment of Long-Lived Assets and Goodwill | Impairment of Long-Lived Assets and Goodwill We evaluate long-lived assets (including intangible assets with finite lives) for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. We also evaluate goodwill for impairment annually on October 1 and whenever events or changes in circumstances indicate that an impairment may exist. The determination of the existence of these and other indications of impairment involves judgments that are subjective in nature and may require the use of estimates in forecasting future results and cash flows. |
Cash, Cash Equivalents and Restricted Cash | Cash, Cash Equivalents and Restricted Cash For purposes of reporting cash and cash equivalents, highly liquid investments with original maturities of three months or less at the date of purchase are considered to be cash equivalents. The following table provides a reconciliation of cash, cash equivalents and restricted cash reported on the Condensed Consolidated Balance Sheets to the sum of such amounts reported on the Condensed Statements of Consolidated Cash Flows: At March 31, At December 31, 2022 2021 Cash, cash equivalents and restricted cash Cash and cash equivalents $ 104 $ 11 Restricted cash, current (a) 35 13 Restricted cash, noncurrent (a) 66 30 Total cash, cash equivalents and restricted cash on the Condensed Statements of Consolidated Cash Flows $ 205 $ 54 ____________ (a) Restricted cash represents amounts deposited with Oncor by our customers that are subject to return in accordance with the PUCT rules, ERCOT requirements or our tariffs, relating to generation interconnection and construction and/or extension of electric delivery system facilities. We maintain these amounts in a separate escrow account. |
Contingencies | Contingencies Our financial results may be affected by judgments and estimates related to contingencies. For loss contingencies, we accrue the loss if an event has occurred on or before the balance sheet date, and: information available through the date we file our financial statements indicates it is probable that a loss has been incurred, given the likelihood of uncertain future events; and the amount of the loss can be reasonably estimated. We do not accrue contingencies that might result in gains. We continuously assess contingencies for litigation claims, environmental remediation and other events. See Note 6 for a discussion of contingencies. |
Effects of Reference Rate Reform on Financial Reporting | Effects of Reference Rate Reform on Financial Reporting Our Credit Facility uses LIBOR as a benchmark for establishing interest rates but incorporates a transition mechanism for the phase-out of LIBOR. In the event we modify our Credit Facility related to the phase-out of LIBOR, we will evaluate the optional expedients and exceptions under ASU No. 2020-04. The standard allows entities to account for contract modifications as an event that does not require reassessment or remeasurement (i.e., as a continuation of the existing contract). |
