Accounting Policies [Abstract]
Business And Significant Accounting Policies	BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES Description of Business References in this report to "the Company" are to EFIH and/or its direct and indirect subsidiaries, as apparent in the context. See Glossary for defined terms. EFIH, a direct, wholly owned subsidiary of EFH Corp., is a Dallas, Texas-based holding company with no operations or operating assets, whose wholly owned subsidiary, Oncor Holdings, holds a majority interest (approximately 80% ) in Oncor. Oncor is a regulated electricity transmission and distribution company principally engaged in providing delivery services to REPs, including subsidiaries of TCEH, that sell electricity to residential, business and other consumers in Texas. EFIH has no reportable business segments. Oncor Holdings and its subsidiaries (the Oncor Ring-Fenced Entities) are not consolidated in EFIH's financial statements in accordance with consolidation accounting standards related to variable interest entities (VIEs) (see Note 3 ). Various ring-fencing measures have been taken to enhance the credit quality of Oncor. Such measures include, among other things: the ownership of a 19.75% equity interest in Oncor by Texas Transmission; maintenance of separate books and records for the Oncor Ring-Fenced Entities; Oncor's board of directors being comprised of a majority of independent directors, and prohibitions on the Oncor Ring-Fenced Entities providing credit support to, or receiving credit support from, any member of the Texas Holdings Group. The assets and liabilities of the Oncor Ring-Fenced Entities are separate and distinct from those of the Texas Holdings Group, and none of the assets of the Oncor Ring-Fenced Entities are available to satisfy the debt or contractual obligations of any member of the Texas Holdings Group. Oncor's operations are conducted, and its cash flows managed, independently from the Texas Holdings Group. Consistent with the ring-fencing measures discussed above, the assets and liabilities of the Oncor Ring-Fenced Entities have not been, and are not expected to be, substantively consolidated with the assets and liabilities of the Debtors in the Chapter 11 Cases. Bankruptcy Proceeding On April 29, 2014 (the Petition Date), EFH Corp. and the substantial majority of its direct and indirect subsidiaries, including EFIH, EFCH and TCEH but excluding the Oncor Ring-Fenced Entities (collectively, the Debtors), filed voluntary petitions for relief (the Bankruptcy Filing) under Chapter 11 of the United States Bankruptcy Code (the Bankruptcy Code) in the United States Bankruptcy Court for the District of Delaware (the Bankruptcy Court). See Note 2 for further discussion regarding the Chapter 11 Cases. Basis of Presentation, Including Application of Bankruptcy Accounting The condensed consolidated financial statements have been prepared in accordance with US GAAP. The condensed consolidated financial statements have been prepared as if EFIH is a going concern and contemplate the realization of assets and liabilities in the normal course of business. The condensed consolidated financial statements reflect the application of Financial Accounting Standards Board Accounting Standards Codification 852, Reorganizations (ASC 852). During the pendency of the Chapter 11 Cases, the Debtors will operate their businesses as debtors-in-possession under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code. ASC 852 applies to entities that have filed a petition for bankruptcy under Chapter 11 of the Bankruptcy Code. The guidance requires that transactions and events directly associated with the reorganization be distinguished from the ongoing operations of the business. In addition, the guidance provides for changes in the accounting and presentation of liabilities. See Notes 7 and 9 for discussion of these accounting and reporting changes. Investments in unconsolidated subsidiaries, which are 50% or less owned and/or do not meet accounting standards criteria for consolidation, are accounted for under the equity method (see Note 3 ). Adjustments (consisting of normal recurring accruals) necessary for a fair presentation of the results of operations and financial position have been included therein. All intercompany items and transactions have been eliminated in consolidation. Certain information and footnote disclosures normally included in annual consolidated financial statements prepared in accordance with US GAAP have been omitted pursuant to the rules and regulations of the SEC. Because the condensed consolidated interim financial statements do not include all of the information and footnotes required by US GAAP, they should be read in conjunction with the audited financial statements and related notes included in EFIH's 2015 Form 10-K. The results of operations for an interim period may not give a true indication of results for a full year. All dollar amounts in the financial statements and tables in the notes are stated in millions of US dollars unless otherwise indicated. Use of Estimates Preparation of financial statements requires estimates and assumptions about future events that affect the reporting of assets and liabilities at the balance sheet dates and the reported amounts of income and expense, including fair value measurements and estimates of expected allowed claims. 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.

Reorganizations [Abstract]
Chapter 11 Cases	CHAPTER 11 CASES On the Petition Date, EFH Corp. and the substantial majority of its direct and indirect subsidiaries, including EFIH, EFCH and TCEH but excluding the Oncor Ring-Fenced Entities, filed voluntary petitions for relief under Chapter 11 of the United States Bankruptcy Code in the United States Bankruptcy Court for the District of Delaware. During the pendency of the Chapter 11 Cases, the Debtors will operate their businesses as "debtors-in-possession" under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code. Plan of Reorganization In May 2016, the Debtors filed the Plan of Reorganization and the Disclosure Statement with the Bankruptcy Court. In July 2016, in connection with the Merger Agreement (as described below), each of the EFH Debtors and NextEra Energy, Inc. (NEE) agreed to certain amendments to the Plan of Reorganization with respect to the EFH Debtors (the Amended Plan). Pursuant to the terms of the EFH Debtors Plan Support Agreement (as described below), it is expected that the Debtors will file the Amended Plan with the Bankruptcy Court and seek confirmation of the Amended Plan. The Plan of Reorganization provides (and the Amended Plan will provide) that the confirmation and effective date of the Plan of Reorganization with respect to the TCEH Debtors may occur separate from, and independent of, the confirmation and effective date of the Plan of Reorganization with respect to the EFH Debtors. With respect to the TCEH Debtors (and certain EFH Debtors that will become subsidiaries of Reorganized TCEH upon emergence of the TCEH Debtors from the Chapter 11 Cases (the Contributed EFH Debtors)), the Plan of Reorganization, subject to certain conditions, provides for, among other things, a tax-free spin-off from EFH Corp. (the Reorganized TCEH Spin-Off), including a transaction that will result in a step-up in the tax basis of certain TCEH assets contributed to a subsidiary of TCEH (Reorganized TCEH). With respect to the EFH Debtors, the Plan of Reorganization (as will be amended by the Amended Plan), subject to certain conditions and certain regulatory approvals, will provide for, among other things, the acquisition by NEE of the EFH Debtors (as reorganized) after the Reorganized TCEH Spin-Off pursuant to the Merger Agreement (as described below). Information contained in the Plan of Reorganization (including when amended by the Amended Plan) and the Disclosure Statement is subject to change, whether as a result of amendments to such documents, requirements by the Bankruptcy Court, actions of third parties or otherwise. Solely as it pertains to the TCEH Debtors and the Contributed EFH Debtors, the Disclosure Statement has been approved by the Bankruptcy Court, and the confirmation hearing for the Plan of Reorganization is scheduled to commence on August 17, 2016. There can be no assurance that the TCEH Debtors' stakeholders will vote to accept the Plan of Reorganization or that the Bankruptcy Court will confirm the Plan of Reorganization, in each case, as it relates to the TCEH Debtors. With respect to the EFH Debtors, no Disclosure Statement has been approved by the Bankruptcy Court, and no date to confirm the Plan of Reorganization has been scheduled. See Scheduling Matters below. The EFH Debtors and the TCEH Debtors, respectively, will emerge from bankruptcy if and when, in each case, a plan of reorganization receives the requisite approval from the appropriate holders of claims, the Bankruptcy Court enters an order confirming such plan of reorganization and certain conditions to the effectiveness of such plan of reorganization are satisfied. Plan Support Agreement and EFH Debtors Plan Support Agreement In August 2015 (as amended in September 2015 and November 2015), in connection with the Terminated Plan, each of the Debtors entered into a Plan Support Agreement (Plan Support Agreement) with, among other parties, various of their respective creditors, the Sponsor Group and the official committee of TCEH unsecured creditors in order to effect an agreed upon restructuring of the Debtors pursuant to the Terminated Plan or, upon certain events, an Alternative Restructuring (as defined in the Plan Support Agreement) pursuant to another plan of reorganization. The Bankruptcy Court approved the Debtors' entry into the Plan Support Agreement in September 2015. In May 2016, certain first lien creditors of TCEH (the Required TCEH First Lien Creditors) delivered a Plan Support Termination Notice to the Debtors and the other parties to the Plan Support Agreement notifying such parties of the occurrence of a Plan Support Termination Event pursuant to the Plan Support Agreement. The delivery of the Plan Support Termination Notice caused the Terminated Plan to become null and void. The delivery of the Plan Support Termination Notice did not, subject to certain conditions, terminate the obligations under the Plan Support Agreement of certain of the parties thereto to support an Alternative Restructuring pursuant to another plan of reorganization such as the Plan of Reorganization (including as to be amended by the Amended Plan). The parties' obligations with respect to an Alternative Restructuring, which remain in effect (including with respect to the Plan of Reorganization (including as to be amended by the Amended Plan)), may be terminated upon the occurrence of certain events described in the Plan Support Agreement. In addition, under the Plan Support Agreement, the supporting parties have committed to support the inclusion of releases with respect to the claims described in the Settlement Agreement (described below) in the context of an alternative plan (which would become effective when a plan of reorganization contemplating an Alternative Restructuring, such as the Plan of Reorganization (including as to be amended by the Amended Plan), becomes effective). In July 2016, the EFH Debtors and NEE entered into a plan support agreement (the EFH Debtors Plan Support Agreement) to effect an agreed upon restructuring of the EFH Debtors pursuant to the Amended Plan. The EFH Debtors Plan Support Agreement has not yet been approved by the Bankruptcy Court. Settlement Agreement The Settling Parties entered into a settlement agreement (the Settlement Agreement) in August 2015 (as amended in September 2015) to compromise and settle, among other things (a) intercompany claims among the Debtors, (b) claims and causes of actions against holders of first lien claims against TCEH and the agents under the TCEH Senior Secured Facilities, (c) claims and causes of action against holders of interests in EFH Corp. and certain related entities and (d) claims and causes of action against each of the Debtors' current and former directors, the Sponsor Group, managers and officers and other related entities. The Bankruptcy Court approved the Settlement Agreement in December 2015. The Settlement Agreement remains effective, notwithstanding the termination of the Terminated Plan. Merger Agreement In July 2016, EFH Corp. and EFIH entered into an Agreement and Plan of Merger (Merger Agreement) with NEE and a wholly-owned subsidiary of NEE (Merger Sub). Pursuant to the Merger Agreement, at the effective time of the Amended Plan, NEE will acquire the EFH Debtors (as reorganized) as a result of a merger (EFH Debtor Merger) between EFH Corp. and Merger Sub in which Merger Sub will survive as a wholly owned subsidiary of NEE. The consideration payable by NEE pursuant to the Merger Agreement consists primarily of cash paid to certain creditors. A portion of the consideration to be distributed to certain holders of allowed claims and interests in EFH Corp. and EFIH as set forth in the Amended Plan will consist of common stock of NEE. The Merger Agreement contains representations and warranties and interim operating covenants that are customary for an agreement of this nature. The Merger Agreement also includes various conditions precedent to consummation of the transactions, including (a) a condition that certain approvals and rulings be obtained, including from the PUCT and the IRS and (b) a condition that the Reorganized TCEH Spin-Off shall have occurred. NEE will not be required to consummate the EFH Debtor Merger if, among other items, the PUCT approval is obtained but with conditions, commitments or requirements that impose a Burdensome Condition (as defined in the Merger Agreement). NEE's and Merger Sub's obligations under the Merger Agreement are not subject to any financing condition. Prior to approval of the Merger Agreement by the Bankruptcy Court, EFH Corp. and EFIH may continue to solicit acquisition proposals with respect to the EFH Debtors. In addition, following approval of the Merger Agreement by the Bankruptcy Court and until confirmation of the Amended Plan by the Bankruptcy Court, EFH Corp. and EFIH may continue or have discussions or negotiations with respect to acquisition proposals for the EFH Debtors (a) with persons that were in active negotiation at the time of approval of the Merger Agreement by the Bankruptcy Court and (b) with persons that submit an unsolicited acquisition proposal that is, or is reasonably likely to lead to, a Superior Proposal (as defined in the Merger Agreement). The Merger Agreement may be terminated upon certain events, including, among other things: • by either party, if the EFH Debtor Merger is not consummated by March 26, 2017, subject to a 90 -day extension under certain conditions, or • by EFH Corp. or EFIH, until the entry of the confirmation order of the Amended Plan with respect to the EFH Debtors, if their respective board of directors or managers determines, after consultation with its independent financial advisors and outside legal counsel, and based on advice of such counsel, that the failure to terminate the Merger Agreement is inconsistent with its fiduciary duties; provided that a material breach of EFH Corp.'s or EFIH’s obligations under certain provisions of the Merger Agreement has not provided the basis for such determination. Following approval of the Merger Agreement by the Bankruptcy Court, if the Merger Agreement is terminated for certain reasons set forth therein and an alternative transaction is consummated by EFH Corp. or EFIH in which neither NEE nor any of its affiliates obtains direct or indirect ownership of approximately 80% of Oncor, then EFH Corp. and EFIH will pay a termination fee of $275 million to NEE. EFH Corp.'s and EFIH’s respective obligations under the Merger Agreement are subject in all respects to the prior approval of the Bankruptcy Court. Under the terms of the EFH Debtors Plan Support Agreement, the EFH Debtors will seek Bankruptcy Court approval of the Merger Agreement. Scheduling Matters In May 2016, the Bankruptcy Court entered an order establishing a timeline for approval of a disclosure statement and a hearing to consider confirmation of the Plan of Reorganization as it applies to the TCEH Debtors and the Contributed EFH Debtors, and, separately, establishing a timeline for approval of a disclosure statement and a hearing to consider confirmation of the Plan of Reorganization as it applies to the remaining EFH Debtors. Pursuant to such scheduling order, solely as it pertains to the TCEH Debtors and the Contributed EFH Debtors, the Disclosure Statement has been approved by the Bankruptcy Court, and the confirmation hearing for the Plan of Reorganization is scheduled to commence on August 17, 2016. In June 2016, the Bankruptcy Court entered a supplement to its May 2016 order adjourning the schedule solely with respect to the EFH Debtors' schedule. The Debtors expect that the Bankruptcy Court will set a revised schedule relating to the EFH Debtors beginning in the third quarter of 2016. The timelines set forth in the scheduling order are subject to further revision by the Bankruptcy Court, and may change based on subsequent orders entered by the Bankruptcy Court (on its own, upon the motion of a party, or upon the Debtors' request). Tax Matters In June 2014, EFH Corp. filed a request with the IRS for a private letter ruling, which request has been supplemented from time to time in response to requests from the IRS for information or as required by changes in the contemplated transactions (as supplemented, the Private Letter Ruling). In July 2016, the Debtors received the Private Letter Ruling. It provides, among other things, for certain rulings regarding the qualification of (a) the transfer of certain assets and ordinary course operating liabilities to Reorganized TCEH and (b) the distribution of the equity of Reorganized TCEH, the cash proceeds from Reorganized TCEH debt, if any, the cash proceeds from the sale of preferred stock in a newly-formed entity, and the right to receive payments under a tax receivables agreement (if any), to holders of TCEH first lien claims, as a reorganization qualifying for tax-free treatment to the extent of the Reorganized TCEH stock received. In addition to the Private Letter Ruling, the Debtors are pursuing and expect to receive the required tax opinions that will supplement the Private Letter Ruling, as required by the Plan of Reorganization with respect to the TCEH Debtors. The Merger Agreement provides that a closing condition to the EFH Debtor Merger is the receipt of a supplemental private letter ruling (the Supplemental Ruling) from the IRS regarding the impact of the EFH Debtor Merger on certain rulings received in the Private Letter Ruling. The Debtors expect to submit a request to the IRS for the Supplemental Ruling during 2016 as the transaction and bankruptcy process progresses. The Supplemental Ruling is only required for the consummation of the transactions contemplated by the EFH Debtor Merger and not for the emergence of the TCEH Debtors (and the Contributed EFH Debtors) as contemplated by the Plan of Reorganization. Implications of the Chapter 11 Cases EFIH's ability to continue as a going concern is contingent upon, among other factors, its ability to comply with the financial and other covenants contained in the DIP Facility described in Note 8 , its ability to obtain new debtor in possession financing in the event the DIP Facility were to expire during the pendency of the Chapter 11 Cases, EFIH's ability to complete a Chapter 11 plan of reorganization in a timely manner, including obtaining creditor and Bankruptcy Court approval of such plan, obtaining applicable regulatory approvals required for such plan and EFIH's ability to obtain any exit financing needed to implement such plan. These circumstances and uncertainties inherent in the bankruptcy proceedings raise substantial doubt about EFIH's ability to continue as a going concern. Pre-Petition Claims Holders of the substantial majority of pre-petition claims were required to file proofs of claims by the bar date established by the Bankruptcy Court. A bar date is the date by which certain claims against the Debtors must be filed if the claimants wish to receive any distribution in the Chapter 11 Cases. The Bankruptcy Court established a bar date of October 27, 2014 for the substantial majority of claims. In addition, in July 2015, the Bankruptcy Court entered an order establishing December 14, 2015 as the bar date for certain asbestos claims that arose or are deemed to have arisen before the Petition Date, except for certain specifically exempt claims. Since the Petition Date and prior to the applicable bar dates (which have expired), the Debtors have received approximately 41,300 filed pre-petition claims, including approximately 30,900 in filed asbestos claims. The Debtors have substantially completed the process of reconciling all non-asbestos claims that were filed and have recorded such claims at the expected allowed amount. As of August 2, 2016 , approximately 5,700 of those claims have been settled, withdrawn or expunged. The Debtors continue to work with creditors regarding certain non-asbestos claims to determine the ultimate amount of the allowed claims. Differences between those final allowed claims and the liabilities recorded in the condensed consolidated balance sheets will be recognized as reorganization items in the Debtors condensed statements of consolidated loss as they are resolved. The resolution of such claims could result in material adjustments to their financial statements. Certain claims filed or reflected in the Debtor's schedules of assets and liabilities will be resolved on the applicable effective date of the applicable plan of reorganization, including certain claims filed by holders of funded debt and contract counterparties. Claims that remain unresolved or unreconciled through the filing of this report have been estimated based upon management's best estimate of the likely claim amounts that the Bankruptcy Court will ultimately allow. Separation of the EFH Debtors and the TCEH Debtors Upon the effective date of the Plan of Reorganization as it relates to the TCEH Debtors (and the EFH Contributed Debtors), the EFH Debtors and the TCEH Debtors (together with the EFH Contributed Debtors) will be separated and no longer be affiliated companies. In addition to the plan of reorganization, the separation will be effectuated by a separation agreement, a transition services agreement and a tax matters agreement. A proposed form of each of these agreements was filed with the Bankruptcy Court by the Debtors in July 2016. These agreements must be approved by the Bankruptcy Court and, as a result, are subject to change.

Investment In Oncor Holdings [Abstract]
Investment In Oncor Holdings	INVESTMENT IN ONCOR HOLDINGS EFIH has a wholly owned subsidiary, Oncor Holdings, which holds an approximate 80% equity interest in Oncor. Oncor Holdings is considered a variable interest entity (VIE). A VIE is an entity with which EFIH has a relationship or arrangement that indicates some level of control over the entity or results in economic risks to EFIH. Accounting standards require consolidation of a VIE if EFIH has (a) the power to direct the significant activities of the VIE and (b) the right or obligation to absorb profit and loss from the VIE (i.e., EFIH is the primary beneficiary of the VIE). In determining the appropriateness of consolidation of a VIE, EFIH evaluates its purpose, governance structure, decision making processes and risks that are passed on to its interest holders. EFIH also examines the nature of any related party relationships among the interest holders of the VIE and the nature of any special rights granted to the interest holders of the VIE. EFIH does not consolidate Oncor Holdings and instead accounts for it as an equity method investment because the structural and operational ring-fencing measures discussed in Note 1 prevent EFIH from having power to direct the significant activities of Oncor Holdings or Oncor. In accordance with accounting standards, EFIH accounts for its investment in Oncor Holdings under the equity method, as opposed to the cost method, based on its level of influence over its activities. The carrying value of EFIH's variable interest in Oncor Holdings totaled approximately $6.121 billion and $6.059 billion at June 30, 2016 and December 31, 2015 , respectively, and is reported as investment in Oncor Holdings in EFIH's condensed consolidated balance sheets. EFIH's maximum exposure to loss from this investment does not exceed its carrying value. See Note 12 for discussion of Oncor Holdings' and Oncor's transactions with EFH Corp. and its other subsidiaries. Distributions from Oncor Holdings and Related Considerations — Oncor Holdings' distributions of earnings to EFIH totaled $86 million and $120 million for the six months ended June 30, 2016 and 2015 , respectively. Distributions may not be paid except to the extent Oncor maintains a required regulatory capital structure as discussed below. At June 30, 2016 , $98 million was eligible to be distributed to Oncor's members after taking into account the regulatory capital structure limit. The boards of directors of each of Oncor and Oncor Holdings can withhold distributions to the extent the applicable board determines in good faith that it is necessary to retain such amounts to meet expected future requirements of Oncor and/or Oncor Holdings. Oncor's distributions are limited by its regulatory capital structure, which is required to be at or below the assumed debt-to-equity ratio established periodically by the PUCT for ratemaking purposes, which is currently set at 60% debt to 40% equity. At June 30, 2016 , Oncor's regulatory capitalization ratio was 59.4% debt to 40.6% equity. For purposes of this ratio, debt is calculated as long-term debt 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 US GAAP, excluding the effects of accounting for the Merger (which included recording the initial goodwill and fair value adjustments and the subsequent related impairments and amortization). EFH Corp., Oncor Holdings, Oncor and Oncor's minority investor are parties to a Federal and State Income Tax Allocation Agreement. Additional income tax amounts receivable or payable may arise in the normal course under that agreement. Oncor Holdings Financial Statements — Condensed statements of consolidated income of Oncor Holdings and its subsidiaries for the three and six months ended June 30, 2016 and 2015 are presented below: Three Months Ended June 30, Six Months Ended June 30, 2016 2015 2016 2015 Operating revenues $ 948 $ 938 $ 1,891 $ 1,884 Operation and maintenance expenses (389 ) (367 ) (791 ) (746 ) Depreciation and amortization (193 ) (220 ) (403 ) (437 ) Taxes other than income taxes (107 ) (108 ) (220 ) (220 ) Other income and (deductions) — net (3 ) (6 ) (8 ) (7 ) Interest expense and related charges (84 ) (84 ) (168 ) (165 ) Income before income taxes 172 153 301 309 Income tax expense (65 ) (58 ) (116 ) (119 ) Net income 107 95 185 190 Net income attributable to noncontrolling interests (22 ) (20 ) (38 ) (39 ) Net income attributable to Oncor Holdings $ 85 $ 75 $ 147 $ 151 Assets and liabilities of Oncor Holdings at June 30, 2016 and December 31, 2015 are presented below: June 30, December 31, ASSETS Current assets: Cash and cash equivalents $ 2 $ 26 Restricted cash — 38 Trade accounts receivable — net 407 388 Trade accounts and other receivables from affiliates 124 118 Income taxes receivable from EFH Corp. 90 107 Inventories 95 82 Prepayments and other current assets 98 88 Total current assets 816 847 Other investments 99 97 Property, plant and equipment — net 13,439 13,024 Goodwill 4,064 4,064 Regulatory assets — net 1,184 1,194 Other noncurrent assets 45 31 Total assets $ 19,647 $ 19,257 LIABILITIES Current liabilities: Short-term borrowings $ 1,133 $ 840 Long-term debt due currently — 41 Trade accounts payable — nonaffiliates 213 150 Income taxes payable to EFH Corp. 11 20 Accrued taxes other than income 106 181 Accrued interest 82 82 Other current liabilities 117 144 Total current liabilities 1,662 1,458 Accumulated deferred income taxes 2,039 1,985 Long-term debt, less amounts due currently 5,650 5,646 Other noncurrent liabilities and deferred credits 2,326 2,306 Total liabilities $ 11,677 $ 11,395

In consideration of the Bankruptcy Filing, EFIH fully reserved all amounts under that agreement because of the significant uncertainty regarding their ultimate settlement, resulting in charges of $65 million and $135 million for the three and six months ended June 30, 2015 . In December 2015, the Bankruptcy Court approved the Settlement Agreement, which settled the intercompany claims among the Debtors, including the $173 million income tax receivable from EFH Corp. that had previously been fully reserved (see Note 2 ).

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES EFH Corp. files a US federal income tax return that includes the results of EFCH, EFIH, Oncor Holdings and TCEH. Oncor is a partnership for US federal income tax purposes and is not a corporate member of the EFH Corp. consolidated group. EFH Corp. and certain of its subsidiaries (including EFCH, EFIH, and TCEH, but not including Oncor Holdings and Oncor) are parties to a Federal and State Income Tax Allocation Agreement, which provides, among other things, that any corporate member or disregarded entity in the EFH Corp. group is required to make payments to EFH Corp. in an amount calculated to approximate the amount of tax liability such entity would have owed if it filed a separate corporate tax return. The Plan of Reorganization provides that upon the effective date of the plan, as it relates to the TCEH Debtors, that the TCEH Debtors will reject this agreement. Additionally, under the terms of the Settlement Agreement, no further cash payments among the Debtors will be made in respect of federal income taxes. The EFH Corp. group has elected to continue to allocate federal income taxes among the entities that are parties to the Federal and State Income Tax Allocation Agreement. The Settlement Agreement did not alter the allocation and payment for state income taxes, which will continue to be settled. EFH Corp., Oncor Holdings, Oncor and Oncor's minority investors are parties to a separate Federal and State Income Tax Allocation Agreement, which governs the computation of federal income tax liability among such parties, and similarly provides, among other things, that each of Oncor Holdings and Oncor will pay EFH Corp. its share of an amount calculated to approximate the amount of tax liability such entity would have owed if it filed a separate corporate tax return. The Settlement Agreement had no impact on the tax sharing agreement among EFH, Oncor Holdings and Oncor. Accordingly, EFIH's income tax expense and related balance sheet amounts are recorded as if EFIH files its own corporate income tax returns. Deferred income taxes are provided for temporary differences between the book and tax basis of assets and liabilities as required under accounting rules. Income tax assets and liabilities related to pushed down debt are settled as membership interests transactions. In evaluating EFIH's ability to utilize its deferred tax assets related to its net operating losses, EFIH considers all available positive and negative information, including scheduled reversals of deferred tax liabilities, taxable income, tax-planning strategies, and results of operations. Due to the uncertainty of the ultimate recovery by EFIH of the benefit of its NOLs, a valuation allowance had been recorded on EFIH’s net deferred tax assets. As of June 30, 2016 that valuation allowance totaled $519 million . The income tax benefits for the three and six months ended June 30, 2016 were offset by charges directly to EFIH’s membership interests (see Note 11). The calculation of EFIH's effective tax rate is as follows: Three Months Ended June 30, Six Months Ended June 30, 2016 2015 2016 2015 Loss before income taxes and equity in earnings of unconsolidated subsidiaries $ (78 ) $ (142 ) $ (172 ) $ (555 ) Income tax benefit $ 18 $ 60 $ 26 $ 125 Effective tax rate 23.1 % 42.3 % 15.1 % 22.5 % For the three months ended June 30, 2016 , the effective tax rate was lower than the US Federal statutory rate of 35% due primarily to the valuation allowance against deferred tax assets and nondeductible legal and other professional services costs related to the Chapter 11 Cases. For the three months ended June 30, 2015 , the effective rate was higher than the US Federal Statutory rate of 35% due primarily to the decrease in valuation allowance recorded against deferred income tax assets, partially offset by the effect of the reserve against the income tax receivable from EFH Corp. that was recorded without income tax benefit and nondeductible legal and other professional services costs related to the Chapter 11 Cases. For the six months ended June 30, 2016 and 2015 , the effective tax rate was lower than the US Federal statutory rate of 35% due primarily to the valuation allowance against deferred tax assets and nondeductible legal and other professional services costs related to the Chapter 11 Cases.

Interest expense for the three and six months ended June 30, 2016 and 2015 reflects interest paid and accrued on debtor in possession financing (see Note 8 ) and for the six months ended June 30, 2015 reflects post-petition interest paid on EFIH's Second Lien Notes as approved by the Bankruptcy Court in March 2015 (see Note 9 ). The Bankruptcy Code generally restricts payment of interest on pre-petition debt, subject to certain exceptions. The Bankruptcy Court approved post-petition interest payments on the EFIH Second Lien Notes in March 2015 as discussed in Note 9 . Additional interest payments may also be made upon approval by the Bankruptcy Court (see Note 10 ). Other than amounts ordered or approved by the Bankruptcy Court, effective on the Petition Date, EFIH discontinued recording interest expense on outstanding pre-petition debt classified as LSTC. The table below shows contractual interest amounts, which are amounts due under the contractual terms of the outstanding debt, including debt subject to compromise during the Chapter 11 Cases. Interest expense reported in the condensed statements of consolidated income (loss) does not include contractual interest on pre-petition debt classified as LSTC totaling $101 million for both the three months ended June 30, 2016 and 2015 , and $202 million and $163 million for the six months ended June 30, 2016 and 2015, respectively, which has been stayed by the Bankruptcy Court effective on the Petition Date. Of the $235 million of post-petition interest paid on the EFIH Second Lien Notes during the six months ended June 30, 2015 , $50 million is contractually related to 2015, which is $163 million lower than the contractual requirement for the period. The remaining $185 million of interest paid on the EFIH Second Lien Notes related to contractual interest from 2014, which was accrued and paid in 2015 upon Bankruptcy Court approval.

Debtor-In-Possession Borrowings [Abstract]
Debtor-in-Possession Borrowings Facilities	DEBTOR-IN-POSSESSION BORROWING FACILITIES DIP Facility and EFIH Second Lien Notes Repayment — The Bankruptcy Court approved the DIP Facility in June 2014. The DIP Facility provides for a $5.4 billion first-lien debtor-in-possession financing facility. In March 2015, $750 million of cash borrowings were used to repay $445 million principal amount of EFIH Second Lien Notes (including accrued and unpaid pre-petition interest of $55 million and post-petition interest of $235 million ) and certain fees (see Note 9 ). As of June 30, 2016 , remaining cash on hand from borrowings under the DIP Facility, net of fees, totaled approximately $275 million , which was held as cash and cash equivalents. In the June 30, 2016 condensed consolidated balance sheet, the borrowings under the DIP Facility are reported as current liabilities. In January 2016, the Debtors paid a $14 million extension fee to extend the maturity date of the DIP Facility to December 2016. The terms of the DIP Facility were otherwise unchanged. The DIP Facility must be repaid in full prior to the EFIH Debtors emergence from the Chapter 11 Cases. The principal amounts outstanding under the DIP Facility bear interest based on applicable LIBOR rates, subject to a 1% floor, plus 3.25% . At both June 30, 2016 and December 31, 2015 , outstanding borrowings under the DIP Facility totaled $5.4 billion at an annual interest rate of 4.25% . The DIP Facility is a non-amortizing loan that may, subject to certain limitations, be voluntarily prepaid by the EFIH Debtors, in whole or in part, without any premium or penalty. The DIP Facility will mature on the earlier of (a) the effective date of any plan of reorganization, (b) upon the event of the sale of substantially all of EFIH's assets or (c) December 2016. EFIH's obligations under the DIP Facility are secured by a first lien covering substantially all of EFIH's assets, rights and properties, subject to certain exceptions set forth in the DIP Facility. The DIP Facility provides that all obligations thereunder constitute administrative expenses in the Chapter 11 Cases, with administrative priority and senior secured status under the Bankruptcy Code and, subject to certain exceptions set forth in the DIP Facility, will have priority over any and all administrative expense claims, unsecured claims and costs and expenses in the Chapter 11 Cases. The DIP Facility provides for affirmative and negative covenants applicable to EFIH and EFIH Finance, including affirmative covenants requiring EFIH and EFIH Finance to provide financial information, budgets and other information to the agents under the DIP Facility, and negative covenants restricting EFIH's and EFIH Finance's ability to incur additional indebtedness, grant liens, dispose of assets, pay dividends or take certain other actions, in each case except as permitted in the DIP Facility. The DIP Facility also includes a minimum liquidity covenant pursuant to which EFIH cannot allow the amount of its unrestricted cash (as defined in the DIP Facility) to be less than $150 million . As of June 30, 2016 , EFIH was in compliance with this minimum liquidity covenant. The Oncor Ring-Fenced Entities are not restricted subsidiaries for purposes of the DIP Facility. The DIP Facility provides for certain customary events of default, including events of default resulting from non-payment of principal, interest or other amounts when due, material breaches of representations and warranties, material breaches of covenants in the DIP Facility or ancillary loan documents, cross-defaults under other agreements or instruments and the entry of material judgments against EFIH. Upon the existence of an event of default, the DIP Facility provides that all principal, interest and other amounts due thereunder will become immediately due and payable, either automatically or at the election of specified lenders. The DIP Facility permits, subject to certain terms, conditions and limitations set forth in the DIP Facility, EFIH to incur incremental junior lien subordinated debt in an aggregate amount not to exceed $3 billion

Liabilities Subject to Compromise	LIABILITIES SUBJECT TO COMPROMISE (LSTC) The amounts classified as LSTC reflect the company's estimate of pre-petition liabilities and other expected allowed claims to be addressed in the Chapter 11 Cases and may be subject to future adjustment as the Chapter 11 Cases proceed. The following table presents LSTC as reported in the condensed consolidated balance sheets at June 30, 2016 and December 31, 2015 : June 30, December 31, Notes, loans and other debt per the following table $ 3,273 $ 3,273 Accrued interest on notes, loans and other debt 81 81 Total liabilities subject to compromise $ 3,354 $ 3,354 Pre-Petition Notes, Loans and Other Debt Reported as LSTC Amounts presented below represent principal amounts of pre-petition notes, loans and other debt reported as LSTC.

Senior Toggle Notes due November 1, 2017 13 13 Total pushed down debt 30 30 Total debt $ 3,273 $ 3,273 ________________ (a) Represents 50% of the amount of these EFH Corp. securities guaranteed by EFIH and pushed down per the discussion below under "Guarantees and Push Down of EFH Corp. Debt." Repayment of EFIH Notes In March 2015, with the approval of the Bankruptcy Court, EFIH used some of its cash to repay (Repayment) $735 million , including interest at contractual rates, in amounts outstanding under EFIH's pre-petition 11.00% Fixed Senior Secured Second Lien Notes due October 1, 2021 (11.00% Notes) and 11.75% Fixed Senior Secured Second Lien Notes due March 1, 2022 (11.75% Notes) and $15 million in certain fees and expenses of the trustee for such notes. The Repayment resulted in an $84 million reduction in the principal amount of the 11.00% Notes, a $361 million reduction in the principal amount of the 11.75% Notes and the payment of $235 million and $55 million of accrued and unpaid post-petition and pre-petition interest, respectively, at contractual rates. The Repayment required the requisite consent of the lenders under the DIP Facility. EFIH received such consent from approximately 97% of the lenders under the DIP Facility in consideration of an aggregate consent fee equal to approximately $13 million . Information Regarding Significant Pre-Petition Debt See Note 9 to the Financial Statements in EFIH's 2015 Form 10-K for information regarding its pre-petition debt. There have been no changes in pre-petition debt since December 31, 2015. Guarantees and Push Down of EFH Corp. Debt Merger-related debt of EFH Corp. and its subsidiaries consists of debt issued or existing at the time of the Merger. Debt issued in exchange for Merger-related debt is considered Merger-related. Debt issuances for cash are considered Merger-related debt to the extent the proceeds are used to repurchase Merger-related debt. EFCH and EFIH (excluding their subsidiaries) fully and unconditionally guarantee on a joint and several basis the Merger-related debt of EFH Corp. (parent). Such debt was pushed down in accordance with SEC Staff Accounting Bulletin Topic 5-J, prior to being rescinded. As a result, a portion of such debt and related interest expense is reflected in EFIH's financial statements. Merger-related debt of EFH Corp. held by its subsidiaries is not subject to push down. Pre-petition debt guaranteed and subject to push down at June 30, 2016 and December 31, 2015 totals $60 million and consists of $33 million principal amount of EFH Corp. 10.875% Notes and $27 million principal amount of EFH Corp. Toggle Notes. The amount reflected in EFIH's condensed consolidated balance sheets as pushed down pre-petition debt ( $30 million at both June 30, 2016 and December 31, 2015 , as shown in the debt table above) represents 50% of the principal amount of the EFH Corp. Merger-related debt guaranteed. This percentage reflects the fact that at the time of the Merger, the equity investments of EFCH and EFIH in their respective operating subsidiaries were essentially equal amounts. Because payment of principal and interest on the debt is the responsibility of EFH Corp., EFIH records the settlement of such amounts as noncash capital contributions from EFH Corp. There were no payments of interest by EFH Corp. on pre-petition debt pushed down for the six months ended June 30, 2016 and 2015 .

Commitments and Contingencies Disclosure [Abstract]
Commitments And Contingencies	COMMITMENTS AND CONTINGENCIES Guarantees See Note 9 for discussion of EFIH's guarantees of certain EFH Corp. debt. Legal Proceedings From time to time, EFIH may be involved in various legal and administrative proceedings in the normal course of business the ultimate resolutions of which, in the opinion of management, should not have a material effect upon its financial condition, results of operations or liquidity. Make-whole Claims — In May 2014, the indenture trustee for the EFIH 10% First Lien Notes initiated litigation in the Bankruptcy Court seeking, among other things, a declaratory judgment that EFIH is obligated to pay a make-whole premium in connection with the cash repayment of the EFIH First Lien Notes and that such make-whole premium is an allowed secured claim, or in the alternative, an allowed secured or unsecured claim for breach of contract (EFIH First Lien Make-whole Claims). The indenture trustee has alleged that the EFIH First Lien Make-whole Claims are valued at approximately $432 million plus reimbursement of expenses. In separate rulings in March and July 2015, the Bankruptcy Court found that no make-whole premium is due with respect to the EFIH 10% First Lien Notes. In February 2016, the US District Court for the District of Delaware affirmed the Bankruptcy Court's rulings. In February 2016, the Indenture Trustee appealed the District Court's ruling to the US Court of Appeals for the Third Circuit. Oral argument has been scheduled for September 27, 2016. The EFIH Debtors intend to vigorously defend against this appeal. EFIH cannot predict the outcome of this appeal. In June 2014, the indenture trustee for the EFIH Second Lien Notes initiated litigation in the Bankruptcy Court seeking similar relief as the trustee of the EFIH 10% First Lien Notes with respect to the EFIH Second Lien Notes, including among other things, that EFIH is obligated to pay a make-whole premium in connection with any repayment of the EFIH Second Lien Notes and that such make-whole premium would be an allowed secured claim, or in the alternative, an allowed secured or unsecured claim for breach of contract (the EFIH Second Lien Make-whole Claims). If, as of June 30, 2016 , the EFIH Second Lien Make-whole Claims were allowed, the amount of such claims would have been approximately $317 million plus reimbursement of expenses. In October 2015, the Bankruptcy Court issued a finding that no make-whole premium is due with respect to the EFIH Second Lien Notes. In April 2016, the US District Court for the District of Delaware issued a ruling and order affirming the Bankruptcy Court's decision. The indenture trustee has appealed that decision to the US Court of Appeals for the Third Circuit, and that court has consolidated the appeal with the appeal filed by the indenture trustee for the EFIH 10% First Lien Notes described above for the purposes of oral argument and final disposition. Oral argument has been scheduled for September 27, 2016. The EFIH Debtors intend to vigorously defend against this appeal. EFIH cannot predict the outcome of this appeal. In July 2015, the EFIH Debtors filed a claim objection with the Bankruptcy Court regarding the EFIH PIK noteholders' claims for a redemption or make-whole premium and post-petition interest at the contract rate under the EFIH PIK Notes. In October 2015, the Bankruptcy Court issued opinions in favor of the EFIH Debtors. One opinion found that no make-whole premium is due with respect to the EFIH PIK Notes. The second opinion found that the EFIH PIK noteholders' allowed claim does not, as a matter of law, include post-petition interest whether at the contract rate or the Federal Judgment Rate. This opinion did find, however, that, in connection with the confirmation of a plan of reorganization, the Bankruptcy Court could, at its discretion, grant post-petition interest as part of the EFIH PIK noteholders' allowed claim under general principals of equity and that such grant could be at the contract rate, the Federal Judgment Rate or any other amount that the Bankruptcy Court determines to be equitable. The EFIH PIK Noteholders have appealed both rulings to the US District Court for the District of Delaware. With respect to the make-whole premium dispute, the parties have agreed to a briefing schedule that will conclude in August 2016. The appeal of the post-petition interest ruling has been stayed by the US District Court for the District of Delaware pending an equitable proceeding suggested by the Bankruptcy Court's second opinion. No briefing schedule has been set for that equitable proceeding. The EFIH Debtors intend to vigorously defend against the appeals and the award of post-petition interest at a rate higher than the Federal Judgment Rate. EFIH cannot predict the outcome of either of these appeals or any equitable proceeding seeking the award of post-petition interest. In addition, creditors may make additional claims in the Chapter 11 Cases for make-whole or redemption premiums in connection with repayments or settlement of other pre-petition debt. These claims could be material. There can be no assurance regarding the outcome of any of the litigation regarding the validity or, if deemed valid, the amount of these make-whole or redemption claims. Adversary Complaint against Texas Transmission — In October 2015, EFH Corp. filed with the Bankruptcy Court an adversary complaint against Texas Transmission seeking a judgment from the Bankruptcy Court regarding the obligations of Texas Transmission under an investor rights agreement to participate in a sale of EFH Corp.'s interests in Oncor. In April 2016, the Bankruptcy Court announced it would approve EFH Corp.'s motion for summary judgment in full and denied Texas Transmission's motion for a determination that the court lacks authority to enter a final judgment or order in the proceeding. In May 2016, the Bankruptcy Court entered an order dismissing the proceeding as no longer relevant as a result of the termination of the merger agreement relating to the proposed sale of EFH Corp.'s ownership in Oncor.

Stockholders' Equity Note [Abstract]
Membership Interests	MEMBERSHIP INTERESTS Cash Distributions No cash distributions were made in the three or six months ended June 30, 2016 , or 2015. Distribution Restrictions The agreement governing the DIP Facility generally restricts EFIH's ability to make distributions or loans to any of its parent companies or their subsidiaries unless such distributions or loans are expressly permitted under the agreement governing such facility. Under applicable law, EFIH is prohibited from paying any dividend to the extent that immediately following payment of such dividend, there would be no statutory surplus or EFIH would be insolvent. In addition, due to the Chapter 11 Cases, no dividends are eligible to be paid without the approval of the Bankruptcy Court. Affiliate Debt Held by EFIH The amounts of affiliate debt held by EFIH were eliminated as a result of the Settlement Agreement approved by the Bankruptcy Court in December 2015. The elimination of affiliate debt created a $635 million pretax loss for EFIH, which was recorded within membership interests. The indentures governing EFIH's debt do not limit its ability to dividend EFH Corp. debt securities to EFH Corp. so long as EFIH received such securities in exchange for the issuance of EFIH debt. Membership Interests The following table presents the changes (all after tax) to membership interests for the six months ended June 30, 2016 : Capital Accounts Affiliate Debt Held by EFIH Accumulated Other Comprehensive Loss Total Membership Interests Balance at December 31, 2015 $ (2,327 ) $ — $ (91 ) $ (2,418 ) Net income 1 — — 1 Current taxes computed under separate return method (a) (26 ) — — (26 ) Net effects related to Oncor — — 1 1 Balance at June 30, 2016 $ (2,352 ) $ — $ (90 ) $ (2,442 ) ___________ (a) Under the Federal and State Income Tax Allocation Agreement and consistent with GAAP, the income tax provision is computed on a separate return basis. However, under the terms of the Settlement Agreement, no further cash payments among the Debtors will be made with respect to federal income taxes, resulting in a charge directly to membership interests for any current federal taxes.

Related Party Transactions [Abstract]
Related-Party Transactions	RELATED–PARTY TRANSACTIONS The following represent EFIH's significant related-party transactions. Also see Note 11 for a discussion of EFH Corp. and TCEH debt securities held by EFIH that were eliminated in December 2015 as a result of the Settlement Agreement approved by the Bankruptcy Court. • A subsidiary of EFH Corp. bills EFIH for administrative services such as accounting and finance at cost, and EFIH reimburses the subsidiary for the allocated costs on a monthly basis. This expense, which is reported in SG&A expenses, totaled $1 million for both the three months ended June 30, 2016 and 2015 and $3 million and $2 million for the six months ended June 30, 2016 and 2015 , respectively. • EFH Corp. files consolidated federal income tax and Texas state margin tax returns, and under the Federal and State Income Tax Allocation Agreement, allocates income taxes to EFIH substantially as if it were filing its own corporate income tax returns. In December 2015, the Bankruptcy Court approved the Settlement Agreement which settled the intercompany claims among the Debtors, including $173 million fully-reserved income tax receivables from EFH Corp. Pursuant to the Settlement Agreement EFIH has not made any federal income tax payments to EFH Corp. or received any tax refunds from EFH Corp in the three and six months ended June 30, 2016 (see Note 2 ). EFIH made state income tax payments to EFH Corp. of $1 million in the six months ended June 30, 2016 . EFIH did not make any income tax payments to EFH Corp. or receive any tax refunds from EFH Corp. in the six months ended June 30, 2015 . See discussion below regarding allocation of income tax liabilities to Oncor Holdings and Oncor under the Federal and State Income Tax Allocation Agreement. • Affiliates of the Sponsor Group have sold or acquired, and in the future may sell or acquire, debt or debt securities issued by EFIH in open market transactions or through loan syndications. See Note 9 regarding guarantees and push-down of certain EFH Corp. pre-petition debt and Note 11 regarding distributions to, and contributions from, EFH Corp. Significant related-party transactions between Oncor Holdings (including its consolidated subsidiary Oncor) and EFH Corp., other affiliates of EFH Corp. and the Sponsor Group are as follows: • Oncor receives payments from subsidiaries of TCEH for services it provides, principally the delivery of electricity. Revenues recorded by Oncor for these services totaled $216 million and $224 million for the three months ended June 30, 2016 and 2015 , respectively, and $436 million and $460 million for the six months ended June 30, 2016 and 2015 , respectively. The fees are based on rates regulated by the PUCT that apply to all REPs. These revenues from subsidiaries of TCEH represented 23% and 24% of Oncor Holdings' operating revenues for the six months ended June 30, 2016 and 2015 , respectively. Oncor Holdings' condensed consolidated balance sheets at June 30, 2016 and December 31, 2015 reflect current receivables from affiliates totaling $124 million and $118 million , respectively, consisting almost entirely of trade receivables from subsidiaries of TCEH related to these electricity delivery fees. • Oncor pays EFH Corp. subsidiaries for financial and other administrative services and shared facilities at cost. Such amounts increased Oncor's reported operation and maintenance expense by less than $1 million and $5 million for the three months ended June 30, 2016 and 2015 , respectively, and $1 million and $10 million for the six months ended June 30, 2016 and 2015 , respectively. • Under Texas regulatory provisions, the trust fund for decommissioning the Comanche Peak nuclear generation facility (reported on TCEH's consolidated balance sheets) is funded by a delivery fee surcharge collected from REPs by Oncor, as collection agent, and remitted monthly to TCEH. The delivery fee surcharges remitted to TCEH totaled $4 million for both the three months ended June 30, 2016 and 2015 and $8 million for both the six months ended June 30, 2016 and 2015 . • EFH Corp. files a consolidated federal income tax return that includes Oncor Holdings' results. Oncor is not a member of EFH Corp.'s consolidated tax group, but EFH Corp.'s consolidated federal income tax return includes EFH Corp.'s portion of Oncor's results due to EFH Corp.'s equity ownership in Oncor. EFH Corp. also files a consolidated Texas state margin tax return that includes all of Oncor Holdings' and Oncor's results. However, under the Federal and State Income Tax Allocation Agreement, Oncor Holdings and Oncor record their federal income tax and Texas state margin taxes as if Oncor Holdings and Oncor were filing their own corporate income tax returns. At June 30, 2016 , Oncor Holdings' net current amount receivable from EFH Corp. related to federal and state income taxes totaled $79 million , $84 million of which related to Oncor. The $84 million net receivable from EFH Corp. included a $95 million federal income tax receivable, offset by an $11 million state margin tax payable. Additionally, at June 30, 2016 Oncor had a noncurrent tax receivable from EFH Corp. of $65 million and Oncor Holdings had a $2 million noncurrent tax payable to EFH Corp. At December 31, 2015 , Oncor Holdings' net current amount receivable from EFH Corp. related to federal and state income taxes totaled $87 million , $89 million of which related to Oncor. The $89 million net receivable from EFH Corp. included a $109 million federal income tax receivable, offset by a $20 million state margin tax payable. Additionally, at December 31, 2015 Oncor had a noncurrent tax receivable from EFH Corp. of $65 million and Oncor Holdings had a $2 million noncurrent tax payable to EFH Corp. For the six months ended June 30, 2016 , Oncor Holdings and Oncor made income tax payments to EFH Corp totaling $10 million and $18 million , respectively. For the six months ended June 30, 2015 , Oncor Holdings and Oncor made income tax payments to EFH Corp totaling $12 million and $22 million , respectively. • Oncor collected transition surcharges from its customers to recover the payment obligations related to its securitization (transition) bonds issued to recover generation-related regulatory assets on behalf of Oncor Electric Delivery Transition Bond Company LLC. As of June 30, 2016 , Oncor had over-collected transition charges of approximately $10 million which will be refunded to Reps upon PUC approval. Approximately $2 million of the charges will be refunded to TCEH. • Oncor had requirements in place to assure adequate creditworthiness to support TCEH's obligation to collect securitization bond-related (transition) charges on behalf of Oncor Electric Delivery Transition Bond Company LLC. Under these requirements, and as a result of TCEH's credit rating being below investment grade, TCEH was required to post collateral support in an amount equal to estimated transition charges over specified time periods. Accordingly, at December 31, 2015 , TCEH had posted letters of credit and/or cash in the amount of $6 million for Oncor's benefit. In May 2016, the last series of Oncor's securitization bonds matured and the letters of credit were released. • Oncor and Texas Holdings agreed to the terms of a stipulation with major interested parties to resolve all outstanding issues in the PUCT review related to the Merger. As part of this stipulation, TCEH would be required to post a letter of credit in an amount equal to $170 million to secure its payment obligations to Oncor in the event, which has not occurred, two or more rating agencies downgrade Oncor's credit rating below investment grade.

EFIH obtains security pricing from an independent party who uses broker quotes and third-party pricing services to determine fair values. Where relevant, these prices are validated through subscription services such as Bloomberg. The fair value estimates of EFIH's pre-petition notes, loans and other debt reported as liabilities subject to compromise have been excluded from the table above. As a result of EFIH's ongoing Chapter 11 Cases, obtaining the fair value estimates of its pre-petition debt subject to compromise is impractical, and the fair values will ultimately be decided through the Chapter 11 Cases.

Accounting Policies [Abstract]
Basis of Presentation, Including Application of Bankruptcy Accounting	Basis of Presentation, Including Application of Bankruptcy Accounting The condensed consolidated financial statements have been prepared in accordance with US GAAP. The condensed consolidated financial statements have been prepared as if EFIH is a going concern and contemplate the realization of assets and liabilities in the normal course of business. The condensed consolidated financial statements reflect the application of Financial Accounting Standards Board Accounting Standards Codification 852, Reorganizations (ASC 852). During the pendency of the Chapter 11 Cases, the Debtors will operate their businesses as debtors-in-possession under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code. ASC 852 applies to entities that have filed a petition for bankruptcy under Chapter 11 of the Bankruptcy Code. The guidance requires that transactions and events directly associated with the reorganization be distinguished from the ongoing operations of the business. In addition, the guidance provides for changes in the accounting and presentation of liabilities. See Notes 7 and 9 for discussion of these accounting and reporting changes. Investments in unconsolidated subsidiaries, which are 50% or less owned and/or do not meet accounting standards criteria for consolidation, are accounted for under the equity method (see Note 3 ). Adjustments (consisting of normal recurring accruals) necessary for a fair presentation of the results of operations and financial position have been included therein. All intercompany items and transactions have been eliminated in consolidation. Certain information and footnote disclosures normally included in annual consolidated financial statements prepared in accordance with US GAAP have been omitted pursuant to the rules and regulations of the SEC. Because the condensed consolidated interim financial statements do not include all of the information and footnotes required by US GAAP, they should be read in conjunction with the audited financial statements and related notes included in EFIH's 2015 Form 10-K. The results of operations for an interim period may not give a true indication of results for a full year. All dollar amounts in the financial statements and tables in the notes are stated in millions of US dollars unless otherwise indicated.
Use of Estimates	Use of Estimates Preparation of financial statements requires estimates and assumptions about future events that affect the reporting of assets and liabilities at the balance sheet dates and the reported amounts of income and expense, including fair value measurements and estimates of expected allowed claims. 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.
