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 membership interests and Texas Transmission owns 19.75 % of our 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 Sempra and its affiliates and any other direct or indirect 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 Sempra entity or any other 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 in the Sempra Acquisition. That transaction was approved by the PUCT in the Sempra Order, which order outlines certain ring-fencing measures, governance mechanisms and restrictions that apply to Oncor Holdings and Oncor 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. Our LLC Agreement requires PUCT approval of certain revisions to the agreement, including, among other things, revisions to our governance structure and other various ring-fencing measures. 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 LLC 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). 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 subsidiaries or affiliated entities (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 LLC 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 operation 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 such 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 the closing of the Sempra Acquisition; 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; and 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. 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 2023 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 and other factors. Our condensed consolidated financial statements have been prepared in accordance with GAAP governing rate-regulated operations. We also apply the guidance of ASC 810, Consolidations, to determine when an entity that is insufficiently capitalized or not controlled through its voting interests, referred to as a VIE, should be consolidated. All dollar amounts in the financial statements and tables in the notes are stated in U.S. dollars in millions 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 during the period. These estimates include, but are not limited to, the effects of regulation; recovery of long-lived assets; certain assumptions made in accounting for pension and OPEB; asset retirement obligations; income and other taxes; valuation of certain financial assets and liabilities; and accounting for contingencies. 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. Accounting for the Effects of Certain Types of Regulation We are subject to rate regulation and our financial statements reflect regulatory assets and liabilities in accordance with accounting standards related to the effect of certain types of regulation. Regulatory assets and liabilities represent probable future revenues that will be recovered from or refunded to customers through the ratemaking process based on PURA and/or the PUCT’s orders, precedents or substantive rules. Rate regulation is premised on the full recovery of prudently incurred costs and a reasonable rate of return on invested capital subject to PUCT review for reasonableness. Regulatory decisions can have an impact on the recovery of costs, the rate earned on invested capital and the timing and amount of assets to be recovered by rates. See Note 2 for more information regarding regulatory assets and liabilities. Revenue Recognition Oncor’s revenue is billed 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 including a reasonable rate of return on invested capital. Revenues are generally recognized when the underlying service has been provided in an amount prescribed by the related tariff. See Note 3 for additional information regarding revenues. Interest Rate Derivatives, Hedge Accounting and Mark-to-Market 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. Designating interest rate derivative instruments as cash flow hedges is dependent on the business context in which the instrument is being used, the effectiveness of the instrument in offsetting the risk that the future cash flows of interest payments may vary, and other criteria. 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 (loss). Amounts remain in AOCI and are reclassified into net income as the interest expense on the related debt affects net income. T he fair value of an interest rate derivative instrument is recognized on the balance sheet as a derivative asset or liability and changes in the fair value are recognized in net income if the criteria for cash flow hedge accounting are not met or if the instrument is not designated as a cash flow hedge. This recognition is referred to as “mark-to-market” accounting. 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, 2024 2023 Cash, cash equivalents and restricted cash Cash and cash equivalents $ 53 $ 19 Restricted cash, current (a) 34 24 Restricted cash, noncurrent (a) 117 108 Total cash, cash equivalents and restricted cash on the Condensed Statements of Consolidated Cash Flows $ 204 $ 151 ____________ (a) Restricted cash represents amounts deposited with Oncor for customer advances for construction that are subject to probable return in accordance with 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 separate escrow accounts. 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. Accounting Standards Updates (ASU) ASU 2023-07 Segment reporting ( ASC 280 ) In November 2023, the Financial Accounting Standards Board (FASB) issued ASU 2023-07, which expands reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. This ASU requires that a public entity disclose, on an annual and interim basis, significant segment expenses that are regularly provided to an entity's chief operating decision maker (CODM), a description of other segment items by reportable segment, and any additional measures of a segment's profit or loss used by the CODM when deciding how to allocate resources. A public entity that has a single reportable segment is also required to provide all the disclosures required by this ASU and all existing segment disclosures in ASC 280. Annual disclosures are required for fiscal years beginning after December 15, 2023. Interim disclosures are required for periods within fiscal years beginning after December 15, 2024. Retrospective application is required for all prior periods presented, and early adoption is permitted. We plan to adopt the standard on December 31, 2024 and as a result expect to provide enhanced disclosures about segment information. ASU 2023-09 Improvements to Income Tax Disclosures ( ASC 740) In December 2023, the FASB issued ASU 2023-09, which expands income tax disclosure requirements to include additional information related to the rate reconciliation of our effective tax rates to statutory rates, as well as additional disaggregation of taxes paid. This ASU also removed disclosures related to certain unrecognized tax benefits and deferred taxes. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024. This ASU may be applied prospectively or retrospectively, and early adoption is permitted. We plan to adopt the standard on December 31, 2025 and are currently evaluating the effect of the standard on our financial reporting. All other newly issued accounting pronouncements not yet effective have been deemed either immaterial or not applicable . |

Regulatory Matters [Abstract] | |
REGULATORY MATTERS | 2. REGULATORY MATTERS Regulatory Proceedings System Resiliency Plan (PUCT Docket No. 56545) On May 6, 2024, we filed a system resiliency plan for PUCT approval pursuant to recently enacted Texas House Bill 2555 and related rules promulgated by the PUCT. The system resiliency plan requests approval of approximately $ 2.9 billion in capital expenditures and $ 520 million in operation and maintenance expenses over a three-year period to enhance the resiliency of our transmission and distribution system. The three-year period will commence upon PUCT approval of the plan, but is anticipated to be for the years 2025 through 2027. The system resiliency plan proposes various measures to address certain resiliency events, including extreme weather, wildfires, physical security threats, and cybersecurity threats. The statute provides that the PUCT will review and approve, modify, or deny a filed plan within 180 days. We cannot predict the outcome of the proceeding. To the extent our system resiliency plan is approved by the PUCT, we intend to recover distribution-related costs through our interim DCRF rate adjustment, with the unrecovered distribution-related operation and maintenance expenses, depreciation expenses and return on the capital to be recognized as a regulatory asset . Capital Trackers Interim DCRF and TCOS rate adjustments, also known as capital trackers, allow us to recover, subject to reconciliation, the cost of certain distribution and transmission investments, respectively, before the investments are considered for prudency in a comprehensive base rate review. Under PUCT rules, we can file up to two interim DCRF rate adjustment applications in a calendar year for certain distribution-related investments and up to two interim TCOS rate adjustment applications in a calendar year to reflect changes in certain transmission-related investments. These interim rate applications are subject to a regulatory proceeding and PUCT approval. Investments included in these capital trackers are also subject to prudence review by the PUCT in the next comprehensive base rate review following such adjustments, with a potential for the PUCT to also order refunds of previously collected amounts if a particular investment is found to be imprudent or inappropriately included in an interim rate adjustment. TCOS revenues are also impacted by transmission billing units, which are updated annually effective January 1 each year to reflect certain changes in average ERCOT-wide peak electricity demand occurring during the previous calendar year. During the three months ended March 31, 2024, Onc or filed the following interim rate update applications with the PUCT: Filing Type PUCT Docket No. Investment Through Filed Effective Date Annual Revenue Impact (a) DCRF 56306 December 2023 (b) March 2024 (c) $ 81 (c) ____________ (a) Annual revenue impact represents the incremental annual revenue impact, after taking into account revenue effects of prior applicable rate adjustments. (b) Reflects distribution and functionalized distribution-related capital investments generally put into service during the period from July 1, 2023 through December 31, 2023. (c) The 2024 third quarter-expected effective date and annual revenue impact are pending PUCT approval. Comprehensive Base Rate Review (PUCT Docket No. 53601) In April 2023, the PUCT issued a final order in our comprehensive base rate review filed in May 2022 with the PUCT and the cities in our service territory that have retained original jurisdiction over rates. New base rates implementing the final order went into effect in May 2023. In June 2023, the PUCT issued an order on rehearing in response to the motions for rehearing filed by us and certain intervening parties in the proceeding. The order on rehearing made certain technical and typographical corrections to the final order, but otherwise affirmed the material provisions of the final order and did not require modification of the rates that went into effect in May 2023. In September 2023, we filed an appeal in Travis County District Court. The appeal sought judicial review of certain of the order on rehearing’s rate base disallowances (the acquisition premium and its associated amortization costs relating to certain plant facilities acquired by Oncor in 2019, as well as certain of the employee benefit and compensation-related costs that we had previously capitalized) and related expense effects of those disallowances. On February 22, 2024, the court dismissed the appeal for lack of jurisdiction. On March 22, 2024, we appealed that ruling to the Third Court of Appeals in Texas. Regulatory Assets and Liabilities We are subject to rate regulation and our financial statements reflect regulatory assets and liabilities in accordance with accounting standards related to the effect of certain types of regulation. Regulatory assets and liabilities represent probable future revenues that will be recovered from or refunded to customers through the ratemaking process based on PURA and/or the PUCT’s orders, precedents or substantive rules. Rate regulation is premised on the full recovery of prudently incurred costs and a reasonable rate of return on invested capital subject to PUCT review for reasonableness. Regulatory decisions can have an impact on the recovery of costs, the rate earned on invested capital and the timing and amount of assets to be recovered by rates. The following table presents components of our regulatory assets and liabilities and their remaining recovery periods in effect at March 31, 2024.

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 as prescribed by the related tariff. We recognize revenue for the amounts that have been invoiced or 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, EECRF, rate case expense riders and mobile generation riders) 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 collect regulatory assets or refund regulatory liabilities. Alternative Revenue Program The PUCT has implemented an incentive program allowing us to earn energy efficiency program performance bonuses by exceeding PURA-mandated 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, 2024 2023 Operating revenues Revenues contributing to earnings: Distribution base revenues Residential (a) $ 329 $ 243 Large commercial & industrial (b) 305 270 Other (c) 29 38 Total distribution base revenues 663 551 Transmission base revenues (TCOS revenues) Billed to third-party wholesale customers 262 250 Billed to REPs serving Oncor distribution customers, through TCRF 144 141 Total TCOS revenues 406 391 Other miscellaneous revenues 24 17 Total revenues contributing to earnings 1,093 959 Revenues collected for pass-through expenses: TCRF – third-party wholesale transmission service 351 321 EECRF and other revenues 14 12 Total revenues collected for pass-through expenses 365 333 Total operating revenues $ 1,458 $ 1,292 __________ (a) Distribution base revenues from residential customers are generally based on actual monthly consumption (kWh). (b) Depending on size and annual load factor, distribution base revenues from large commercial & industrial customers are based either on actual monthly demand (kilowatts) or the greater of actual monthly demand (kilowatts) or 80 % of peak monthly demand during the prior eleven months. (c) Includes distribution base revenues from small business customers whose billing is generally based on actual monthly consumption (kWh), lighting sites and other miscellaneous distribution base revenues. Customers At March 31, 2024, our distribution business customers primarily consisted of over 100 REPs that sell electricity we distribute to end-use consumers in our certificated service area. The majority of consumers of the electricity we deliver through our distribution business are free to choose their electricity supplier from REPs who compete for their business. Our network transmission revenues are collected from load serving entities benefitting from our transmission system. Our transmission business customers consist of municipally-owned utilities, electric cooperatives and other distribution companies. Revenues from REP subsidiaries of our two largest customers, collectively represented 26 % and 24 %, respectively, of our total operating revenues for the three months ended March 31, 2024. No other customer represented more than 10% of our total operating revenues during such period. 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 | 4. SHORT-TERM BORROWINGS The following table reflects our outstanding short-term borrowings and available unused credit under the $2B Credit Facility and CP Program at March 31, 2024 and December 31, 2023: At March 31, At December 31, 2024 2023 $2B Credit Facility borrowing capacity $ 2,000 $ 2,000 $2B Credit Facility outstanding borrowings - - Commercial paper outstanding (a) - ( 282 ) Total available unused credit $ 2,000 $ 1,718 ____________ (a) The weighted average interest rate for CP Notes was 5.54 % at December 31, 2023. All outstanding CP Notes at December 31, 2023 had maturity dates of less than one year . $2B Credit Facility The $2B Credit Facility has a borrowing capacity of $ 2.0 billion. We have the option to request an increase in our borrowing capacity of up to $ 400 million in $ 100 million minimum increments, subject to certain conditions, including lender approvals. Borrowings under the $2B Credit Facility, if any, are classified as short-term on the balance sheet. Borrowings under the $2B Credit Facility bear interest at a per annum rate equal to, at our option, (i) term SOFR for the interest period relevant to such borrowing, plus an adjustment of 0.10 % (the SOFR Adjustment), plus an applicable margin of between 0.875 % and 1.50 %, depending on certain credit ratings assigned to us, or (ii) an alternate base rate (equal to the greatest of (1) the prime rate as quoted by The Wall Street Journal on such date, (2) the greater of the federal funds effective rate or the overnight bank funding rate, plus 0.50 %, and (3) term SOFR for a one-month interest period on such date, plus the SOFR Adjustment, plus 1.0 %), plus, in the case of clauses (1) through (3), an applicable margin of between 0.00 % and 0.50 %, depending on certain credit ratings assigned to our debt. The $2B Credit Facility also provides for an alternative rate of interest upon the occurrence of certain events related to the current rate of interest benchmark. A commitment fee is payable quarterly in arrears and upon termination or commitment reduction at a rate per annum equal to between 0.075 % and 0.225 %, depending on certain credit ratings assigned to us, of the commitments under the $2B Credit Facility. Letter of credit fees under the $2B Credit Facility are payable quarterly in arrears and upon termination at a rate per annum equal to the applicable margin for adjusted term SOFR under the $2B Credit Facility. Fronting fees in an amount as separately agreed by Oncor and any fronting bank that issues a letter of credit are also payable quarterly in arrears and upon termination to each such fronting bank. The $2B Credit Facility includes sustainability-linked pricing metrics related to specific environmental and employee health and safety sustainability objectives. The $2B Credit Facility provides that the applicable margin and commitment fee may be increased, decreased or have no change depending on our annual performance on the two sustainability-linked pricing metrics set forth in the facility. The maximum pricing adjustment in any given year is +/- 0.01 % on the commitment fee and +/- 0.05 % on the applicable margin. The $2B Credit Facility requires that we maintain a maximum consolidated senior debt to consolidated total capitalization ratio of 0.65 to 1.00 and observe certain customary reporting requirements and other affirmative covenants. The $2B Credit Facility also contains customary events of default for facilities of this type, the occurrence of which would allow the lenders to accelerate all outstanding loans and terminate their commitments, including certain changes in control of Oncor that are not permitted transactions under the $2B Credit Facility and cross-default provisions in the event Oncor or any of its subsidiaries defaults on indebtedness in a principal amount in excess of $ 100 million or receives judgments for the payment of money in excess of $ 100 million that are not discharged or stayed within 60 days. CP Program We maintain the CP Program under which we may issue unsecured CP Notes (with a maturity date not exceeding 397 days from the date of issuance) 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 the $2B Credit Facility discussed above. We may utilize either the CP Program or the $2B Credit Facility, at our option, to meet our funding needs. |

Long-Term Debt [Abstract] | |
LONG-TERM DEBT | 5. LONG-TERM DEBT At March 31, 2024, our long-term debt consisted of fixed rate senior secured notes, variable rate secured debt borrowed under our AR Facility and variable rate unsecured debt borrowed under the $500M Credit Facility. Our senior secured notes are secured equally and ratably by a first priority lien on certain transmission and distribution assets. See “Deed of Trust” below for additional information. Amounts borrowed under our AR Facility are secured by accounts receivable from REPs and certain related rights under our AR Facility. See “AR Facility” below for additional information. Amounts borrowed under the $500M Credit Facility are unsecured. See “$500M Credit Facility” below for additional information. At March 31, 2024 and December 31, 2023, our long-term debt consisted of the following: At March 31, At December 31, 2024 2023 Fixed Rate Senior Secured Notes: 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 5.50 % Senior Notes, Series C, due May 1, 2026 200 200 4.30 % Senior Notes due May 15, 2028 600 600 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 5.34 % Senior Notes, Series D, due May 1, 2031 100 100 7.00 % Senior Notes due May 1, 2032 494 494 4.15 % Senior Notes due June 1, 2032 400 400 4.55 % Senior Notes due September 15, 2032 700 700 7.25 % Senior Notes due January 15, 2033 323 323 5.65 % Senior Notes due November 15, 2033 800 800 5.45 % Senior Notes, Series E, due May 1, 2036 100 100 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 4.60 % Senior Notes due June 1, 2052 400 400 4.95 % Senior Notes due September 15, 2052 900 900 5.35 % Senior Notes due October 1, 2052 300 300 Total fixed rate senior secured notes 13,445 13,445 Variable Rate Secured Debt: AR Facility due April 28, 2027 300 - Variable Rate Unsecured Debt: $500M Credit Facility due February 21, 2027 500 - Total long-term debt 14,245 13,445 Unamortized discount, premium and debt issuance costs ( 146 ) ( 151 ) Less long-term debt, current (a) ( 317 ) - Long-term debt, noncurrent $ 13,782 $ 13,294 ___________ (a) In accordance with ASC 470-10 “Debt”, our ability to refinance $ 183 million of the $ 500 million aggregate principal amount of our 2.75 % Senior Notes due June 1, 2024 on a long-term basis as of March 31, 2024, through the available capacity of our AR Facility , and our intent to refinance such notes on a long-term basis, results in $ 183 million being classified as long-term debt, noncurrent. Deed of Trust Our long-term senior secured notes are secured equally and ratably by a first priority lien on all property acquired or constructed by us for use in our 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. AR Facility In April 2023, we and our bankruptcy-remote special purpose entity Receivables LLC, a wholly-owned subsidiary of Oncor, established the AR Facility, a revolving accounts receivable securitization facility. Under the terms of the AR Facility, Oncor sells or contributes all of its existing and future accounts receivable from REPs and certain related rights to Receivables LLC as contemplated by the terms of the AR Facility. Receivables LLC then pledges those REP receivables and related rights to the lenders under the AR Facility as collateral for borrowings. Oncor serves as servicer of the AR Facility and receives a fee from Receivables LLC equal to 1.00 % per annum of the aggregate unpaid balance of receivables as of the last day of each settlement period. Receivables LLC’s sole business consists of the purchase or acceptance through capital contributions of the receivables and related rights from Oncor and the subsequent retransfer of or granting of a security interest in such receivables and related rights to the administrative agent for the benefit of the lenders pursuant to the receivables financing agreement. Receivables LLC is a separate legal entity with its own separate creditors who will be entitled, upon its liquidation, to have amounts owed to them be satisfied out of Receivables LLC’s assets prior to any assets or value in Receivables LLC becoming available to Receivables LLC’s equity holder. The assets of Receivables LLC are not available to pay creditors of Oncor or any affiliate thereof. Receivables LLC is considered a VIE. See Note 10 for more information related to our consolidated VIE. Oncor has access to the AR Facility, under which Receivables LLC may borrow at any one time an amount equal to the borrowing base. The borrowing base is defined under the receivables financing agreement as an amount equal to the lesser of (i) the facility limit of $ 500 million or (ii) the amount calculated based on the outstanding balance of eligible receivables held as collateral at a particular time, subject to certain reserves, concentration limits, and other limitations. Borrowings under the AR Facility bear interest at the daily cost of asset-backed commercial paper issued by the conduit lenders to fund the loans, plus related dealer commissions and note issuance costs, or, if funded by the committed lenders, a rate per annum equal to SOFR calculated based on term SOFR for a one-month interest period, plus the SOFR Adjustment. Receivables LLC also pays a used and unused fee in connection with the AR Facility. At March 31, 2024, the borrowing base for the AR Facility was $ 483 million and $ 300 million aggregate borrowings were outstanding under the AR Facility. The agreements relating to the AR Facility contain customary representations and warranties, affirmative and negative covenants, and events of default, including but not limited to those providing for the acceleration of amounts owed under the AR Facility if, among other things, Receivables LLC fails to pay interest or other amounts due, Receivables LLC becomes insolvent or subject to bankruptcy proceedings or certain judicial judgments or breaches of certain representations and warranties and covenants. On April 26, 2024, the scheduled termination date of the AR Facility was extended by one year from April 28, 2026 to April 28, 2027. Taking into account the extension, the AR Facility will terminate at the earlier of (i) the scheduled termination date of April 28, 2027, (ii) the date on which the termination date is declared or deemed to have occurred upon the exercise of remedies by the administrative agent, or (iii) the date that is 30 days after notice of termination is provided by Receivables LLC. Subject to the consent of the administrative agent and the lenders, Receivables LLC may, 30 days prior to each anniversary date of the receivables financing agreement, extend the AR Facility in one-year increments subject to lender approvals. $500M Credit Facility On February 21, 2024, we entered into an unsecured revolving $500M Credit Facility. The $500M Credit Facility has a borrowing capacity of $ 500 million and a maturity date of February 21, 2027. The $500M Credit Facility gives us the option to request an increase in our borrowing capacity of up to $ 500 million in $ 100 million minimum increments, subject to certain conditions, including lender approvals. The $500M Credit Facility also provides us with the option to request that each lender extend the term of its commitment for up to two additional one-year periods, subject to certain conditions, including lender approvals. Borrowings under the $500M Credit Facility bear interest at a per annum rate equal to, at our option, (i) term SOFR for the interest period relevant to such borrowing, plus the SOFR Adjustment, plus an applicable margin of between 0.875 % and 1.50 %, depending on certain credit ratings assigned to us, or (ii) an alternate base rate (equal to the greatest of (1) the prime rate publicly announced from time to time by the administrative agent as its prime rate, (2) the federal funds effective rate, plus 0.50 %, and (3) term SOFR for a one-month interest period on such date, plus the SOFR Adjustment, plus 1.0 %), plus, in the case of clauses (1) through (3), an applicable margin of between 0.00 % and 0.50 %, depending on certain credit ratings assigned to our debt. The $500M Credit Facility also provides for an alternative rate of interest upon the occurrence of certain events related to the current rate of interest benchmark. A commitment fee is payable quarterly in arrears and upon termination or commitment reduction at a rate per annum equal to between 0.075 % and 0.625 % of the commitments under the $500M Credit Facility, depending on certain credit ratings assigned to us and the utilization percentage. The utilization percentage is determined by dividing the aggregate principal amount of loans outstanding under the $500M Credit Facility by the total commitments. At March 31, 2024, $ 500 million aggregate borrowings were outstanding under the $500M Credit Facility. Long-Term Debt-Related Activity in the Three Months ended March 31, 2024 AR Facility On January 30, 2024, we borrowed $ 300 million aggregate principal amount under the AR Facility. The proceeds of the borrowing were used for general corporate purposes, including to repay outstanding CP Notes. $500M Credit Facility On February 28, 2024 and March 28, 2024, we borrowed $ 220 million aggregate principal amount and $ 280 million aggregate principal amount, respectively, under the $500M Credit Facility. The proceeds of the borrowings were used for general corporate purposes, including to repay outstanding CP Notes. Long-Term Debt-Related Activity after March 31, 2024 Senior Secured Notes On April 24, 2024, we issued $ 100 million aggregate principal amount of 5.00 % Senior Secured Notes, Series F, due May 1, 2029 (Series F Notes) and $ 50 million aggregate principal amount of 5.49 % Senior Secured Notes, Series G, due May 1, 2054 (Series G Notes, and together with the Series F Notes, the 2024 NPA Notes). The 2024 NPA Notes were issued pursuant to the Note Purchase Agreement, dated March 27, 2024, between Oncor and the purchasers named therein (2024 NPA). We used the proceeds from the sale of the 2024 NPA Notes for general corporate purposes, including to repay outstanding CP Notes. The Series F Notes bear interest at a rate of 5.00 % per annum and mature on May 1, 2029. The Series G Notes bear interest at a rate of 5.49 % per annum and mature on May 1, 2054. Interest on the 2024 NPA Notes will be payable semi-annually on May 1 and November 1, beginning November 1, 2024. Prior to April 1, 2029 in the case of the Series F Notes and November 1, 2053 in the case of the Series G Notes, we may redeem such notes at any time, in whole or in part, at a price equal to 100 % of their principal amount, plus accrued and unpaid interest and a “make-whole” premium. On and after April 1, 2029 in the case of the Series F Notes and November 1, 2053 in the case of the Series G Notes, we may redeem such notes at any time, in whole or in part, at a redemption price equal to 100 % of the principal amount of such notes, plus accrued and unpaid interest. The 2024 NPA also contains customary covenants, restricting, subject to certain exceptions, us from, among other things, entering into mergers and consolidations, and sales of substantial assets. In addition, the 2024 NPA requires that we maintain a consolidated senior debt to consolidated total capitalization ratio of no greater than 0.65 to 1.00 and observe certain customary reporting requirements and other affirmative covenants. The 2024 NPA contains customary events of default, including the failure to pay principal or interest on the 2024 NPA Notes when due, among others. If any such event of default occurs and is continuing, among other remedies provided in the 2024 NPA, the outstanding principal of the 2024 NPA Notes may be declared due and payable. AR Facility On April 29, 2024, we borrowed an additional $ 100 million aggregate principal amount under the AR Facility. The proceeds of the borrowing were used for general corporate purposes, including to repay outstanding CP Notes. Fair Value of Long-Term Debt At March 31, 2024 and December 31, 2023, the estimated fair value of our long-term debt (including current maturities) totaled $ 13.253 billion and $ 12.798 billion, respectively, and the carrying amount totaled $ 14.099 billion and $ 13.294 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 | 6. COMMITMENTS AND CONTINGENCIES Legal/Regulatory Proceedings See Note 2 for information regarding certain regulatory proceedings. We are also involved in other 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 Notes 1 and 2 above and Note 7 to Consolidated Financial Statements in our 2023 Form 10-K for additional information regarding our legal and regulatory proceedings. 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, 2024, we had $ 4 million in GAAP operating leases for temporary emergency electric energy facilities that are treated as capital leas es (referred to as finance leases under current accounting literature) solely for rate-making purposes as required by PURA. 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 Consolidated Financial Statements in our 2023 Form 10-K for additional information on leases. As of March 31, 2024, there was a 15 -year operating lease contract we entered into in December 2023 that is scheduled to commence in the second half of 2024. The estimated $ 64 million present value of the lease obligation is not yet recorded on the Condensed Consolidated Balance Sheets. Sales and Use Tax Audits We are subject to sales and use tax audits in the normal course of business. As of March 31, 2024, the Texas State Comptroller’s office was conducting two sales and use tax audits for audit periods covering July 2013 through December 2017 and January 2018 through December 2022. While the outcome of these ongoing audits is uncertain, based on our analysis, we do not expect the ultimate resolution of these ongoing audits will have a material adverse effect on our financial position, results of operations, or cash flows. In January 2024, we reached a final settlement agreement with the Texas State Comptroller’s office for the sales and use tax audit for the January 2010 through June 2013 audit period that resulted in a $ 63 million refund, net of consulting fees. The effects of the net settlement recorded in the first quarter of 2024 reflect a $ 53 million reduction in property, plant and equipment in the Condensed Consolidated Balance Sheets related to sales tax previously capitalized and a $ 10 million decrease in operation and maintenance expense in the Condensed Statements of Consolidated Income related to sales tax previously expensed. |

Membership Interests [Abstract] | |
MEMBERSHIP INTERESTS | 7. MEMBERSHIP INTERESTS Contributions We received cash contributions from our members of $ 240 million on May 3, 2024. In the three months ended March 31, 2024, we received the following cash contributions from our members: Receipt Date Amount February 16, 2024 $ 240 Distributions The Sempra Order and our LLC 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 our debt-to-equity ratio authorized by the PUCT. 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). In addition, the distribution restrictions also require us to suspend dividends and other distributions (except for contractual tax payments) if the credit rating on our senior secured debt by any of the three major rating agencies falls below BBB (or the equivalent), unless otherwise allowed by the PUCT. Our current authorized regulatory capital structure is 57.5 % debt to 42.5 % equity. The PUCT has the authority to determine what types of debt and equity are included in a utility’s regulatory 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. At March 31, 2024, our regulatory capitalization was 56.5 % debt to 43.5 % equity and as a result we had $ 458 million available to distribute to our members. On April 30, 2024, our board of directors declared a cash distribution of $ 126 million, which was paid to our members on May 1, 2024. In the three months ended March 31, 2024, our board of directors declared, and we paid, the following cash distributions to our members: Declaration Date Payment Date Amount February 14, 2024 February 15, 2024 $ 125 Membership Interests The following tables present the changes to membership interests during the three months ended March 31, 2024 and 2023, net of tax: Capital Account AOCI Total Membership Interests Balance at December 31, 2023 $ 14,388 $ ( 180 ) $ 14,208 Net income 225 - 225 Contributions from members 240 - 240 Distributions to members ( 125 ) - ( 125 ) Cash flow hedges – amount reclassified from AOCI and reported in interest expense and related charges (net of tax) - 1 1 Balance at March 31, 2024 $ 14,728 $ ( 179 ) $ 14,549 Balance at December 31, 2022 $ 13,624 $ ( 162 ) $ 13,462 Net income 103 - 103 Contributions from members 106 - 106 Distributions to members ( 106 ) - ( 106 ) Cash flow hedges – amount reclassified from AOCI and reported in interest expense and related charges (net of tax) - 1 1 Defined benefit pension plans (a) - ( 20 ) ( 20 ) Balance at March 31, 2023 $ 13,727 $ ( 181 ) $ 13,546 ____________ (a) Includes a $ 20 million reclassification from regulatory assets related to employee retirement liabilities to other comprehensive income in the first quarter of 2023, recorded as a result of the final order in our comprehensive base rate review (PUCT Docket No. 53601).

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 maintain a supplemental retirement plan for certain employees whose retirement benefits cannot be fully earned under the qualified retirement plans. See Note 9 to Consolidated Financial Statements in our 2023 Form 10-K for additional information regarding pension plans. OPEB Plans We currently sponsor two OPEB plans. One plan covers eligible current and future retirees whose services are 100 % assigned to Oncor (or a predecessor regulated utility business). Effective January 1, 2018, we established a second plan to cover eligible retirees of Oncor and Vistra (or their predecessors or affiliates) whose employment services were assigned to both Oncor (or a predecessor regulated utility business) and the non-regulated business of Vistra. Vistra is solely responsible for its portion of the liability for retiree benefits related to those retirees. See Note 9 to Consolidated Financial Statements in our 2023 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, 2024 and 2023, were comprised of the following: Three Months Ended March 31, 2024 2023 Components of net pension costs: Service cost $ 6 $ 6 Interest cost (a) 30 31 Expected return on assets (a) ( 29 ) ( 32 ) Amortization of net loss (a) 1 1 Net pension costs 8 6 Net adjustments (b) ( 2 ) 4 Net pension costs recognized as operation and maintenance expense or other deductions $ 6 $ 10 Components of net OPEB costs: Service cost $ 1 $ 1 Interest cost (a) 8 8 Expected return on assets (a) ( 2 ) ( 2 ) Amortization of net loss (a) ( 2 ) ( 8 ) Net OPEB costs 5 ( 1 ) Net adjustments (b) ( 3 ) 9 Net OPEB costs recognized as operation and maintenance expense or other deductions $ 2 $ 8 ___________ (a) The components of net costs other than the service cost component, are recorded in “Other (income) and deductions – net” in Condensed Statements of Consolidated Income. (b) Net adjustments include amounts principally deferred as property, plant and equipment, regulatory assets or regulatory liabilities. The discount rates reflected in net pension and OPEB costs in 2024 are 4.76 %, 4.97 % and 4.99 % 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 2024 cost amounts are 5.78 %, 6.29 % and 6.72 % 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 $ 6 million, respectively, during the three months ended March 31, 2024. Based on funding considerations in the latest actuarial projections, including applicable minimum funding requirements, our future fundings for the pension plans and the OPEB Plans are expected to total $ 90 million and $ 17 million, respectively, during the remainder of 2024 and approximately $ 549 million and $ 135 million, respectively, in the five-year period from 2024 to 2028. Future funding estimates for our pension plans and OPEB Plans are dependent on a variety of variables and assumptions, including investment returns on plan assets, market interest rates, and levels of discretionary contributions over minimum funding requirements, which we continue to monitor. Financial market volatility and its effects on the returns on our plan assets and liability valuations could significantly change our anticipated future funding amounts. |

Related-Party Transactions [Abstract] | |
RELATED-PARTY TRANSACTIONS | 9. RELATED-PARTY TRANSACTIONS The following represents our significant related-party transactions and related matters. 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 which 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 Consolidated Financial Statements in our 2023 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 sheet consisted of the following: At March 31, 2024 At December 31, 2023 STH Texas Transmission Total STH Texas Transmission Total Federal income taxes payable (receivable) $ 13 $ 3 $ 16 $ ( 3 ) $ ( 1 ) $ ( 4 ) Texas margin tax payable 35 - 35 27 - 27 Net payable (receivable) $ 48 $ 3 $ 51 $ 24 $ ( 1 ) $ 23 There were no cash payments made to (received from) members related to income taxes for the three months ended March 31, 2024 and 2023. See Note 7 for information regarding cash 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 $ 4 million during each of the three months ended March 31, 2024 and 2023 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, 2024 and 202 3. |

Business And Significant Accounting Policies [Abstract] | |
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 membership interests and Texas Transmission owns 19.75 % of our 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 Sempra and its affiliates and any other direct or indirect 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 Sempra entity or any other 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 in the Sempra Acquisition. That transaction was approved by the PUCT in the Sempra Order, which order outlines certain ring-fencing measures, governance mechanisms and restrictions that apply to Oncor Holdings and Oncor 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. Our LLC Agreement requires PUCT approval of certain revisions to the agreement, including, among other things, revisions to our governance structure and other various ring-fencing measures. 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 LLC 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). 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 subsidiaries or affiliated entities (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 LLC 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 operation 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 such 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 the closing of the Sempra Acquisition; 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; and 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. |
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 2023 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 and other factors. Our condensed consolidated financial statements have been prepared in accordance with GAAP governing rate-regulated operations. We also apply the guidance of ASC 810, Consolidations, to determine when an entity that is insufficiently capitalized or not controlled through its voting interests, referred to as a VIE, should be consolidated. All dollar amounts in the financial statements and tables in the notes are stated in U.S. dollars in millions 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 during the period. These estimates include, but are not limited to, the effects of regulation; recovery of long-lived assets; certain assumptions made in accounting for pension and OPEB; asset retirement obligations; income and other taxes; valuation of certain financial assets and liabilities; and accounting for contingencies. 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. |
Accounting for the Effects of Certain Types of Regulation | Accounting for the Effects of Certain Types of Regulation We are subject to rate regulation and our financial statements reflect regulatory assets and liabilities in accordance with accounting standards related to the effect of certain types of regulation. Regulatory assets and liabilities represent probable future revenues that will be recovered from or refunded to customers through the ratemaking process based on PURA and/or the PUCT’s orders, precedents or substantive rules. Rate regulation is premised on the full recovery of prudently incurred costs and a reasonable rate of return on invested capital subject to PUCT review for reasonableness. Regulatory decisions can have an impact on the recovery of costs, the rate earned on invested capital and the timing and amount of assets to be recovered by rates. See Note 2 for more information regarding regulatory assets and liabilities. |
Revenue Recognition | Revenue Recognition Oncor’s revenue is billed 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 including a reasonable rate of return on invested capital. Revenues are generally recognized when the underlying service has been provided in an amount prescribed by the related tariff. See Note 3 for additional information regarding revenues. |
Interest Rate Derivatives, Hedge Accounting and Mark-to-Market Accounting | Interest Rate Derivatives, Hedge Accounting and Mark-to-Market 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. Designating interest rate derivative instruments as cash flow hedges is dependent on the business context in which the instrument is being used, the effectiveness of the instrument in offsetting the risk that the future cash flows of interest payments may vary, and other criteria. 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 (loss). Amounts remain in AOCI and are reclassified into net income as the interest expense on the related debt affects net income. T he fair value of an interest rate derivative instrument is recognized on the balance sheet as a derivative asset or liability and changes in the fair value are recognized in net income if the criteria for cash flow hedge accounting are not met or if the instrument is not designated as a cash flow hedge. This recognition is referred to as “mark-to-market” accounting. |
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, 2024 2023 Cash, cash equivalents and restricted cash Cash and cash equivalents $ 53 $ 19 Restricted cash, current (a) 34 24 Restricted cash, noncurrent (a) 117 108 Total cash, cash equivalents and restricted cash on the Condensed Statements of Consolidated Cash Flows $ 204 $ 151 ____________ (a) Restricted cash represents amounts deposited with Oncor for customer advances for construction that are subject to probable return in accordance with 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 separate escrow accounts. |
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. |
Accounting Standards Updates (ASU) | Accounting Standards Updates (ASU) ASU 2023-07 Segment reporting ( ASC 280 ) In November 2023, the Financial Accounting Standards Board (FASB) issued ASU 2023-07, which expands reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. This ASU requires that a public entity disclose, on an annual and interim basis, significant segment expenses that are regularly provided to an entity's chief operating decision maker (CODM), a description of other segment items by reportable segment, and any additional measures of a segment's profit or loss used by the CODM when deciding how to allocate resources. A public entity that has a single reportable segment is also required to provide all the disclosures required by this ASU and all existing segment disclosures in ASC 280. Annual disclosures are required for fiscal years beginning after December 15, 2023. Interim disclosures are required for periods within fiscal years beginning after December 15, 2024. Retrospective application is required for all prior periods presented, and early adoption is permitted. We plan to adopt the standard on December 31, 2024 and as a result expect to provide enhanced disclosures about segment information. ASU 2023-09 Improvements to Income Tax Disclosures ( ASC 740) In December 2023, the FASB issued ASU 2023-09, which expands income tax disclosure requirements to include additional information related to the rate reconciliation of our effective tax rates to statutory rates, as well as additional disaggregation of taxes paid. This ASU also removed disclosures related to certain unrecognized tax benefits and deferred taxes. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024. This ASU may be applied prospectively or retrospectively, and early adoption is permitted. We plan to adopt the standard on December 31, 2025 and are currently evaluating the effect of the standard on our financial reporting. All other newly issued accounting pronouncements not yet effective have been deemed either immaterial or not applicable |
