The representations and warranties contained in any agreement that we have filed as an exhibit to this quarterly report on Form 10-Q or that we have or may publicly file in the future may contain representations and warranties made by and to the parties thereto as of specific dates.

GLOSSARY

When the following terms and abbreviations appear in the text of this report, they have the meanings indicated below.

2011 Form 10-K	EFCH's Annual Report on Form 10-K for the year ended December 31, 2011
Adjusted EBITDA	Adjusted EBITDA means EBITDA adjusted to exclude noncash items, unusual items and other adjustments allowable under certain debt arrangements of TCEH and EFH Corp. See the definition of EBITDA below. Adjusted EBITDA and EBITDA are not recognized terms under US GAAP and, thus, are non-GAAP financial measures. We are providing TCEH's and EFH Corp.'s Adjusted EBITDA in this Form 10-Q (see reconciliations in Exhibits 99(b) and 99(c)) solely because of the important role that Adjusted EBITDA plays in respect of certain covenants contained in the debt arrangements. We do not intend for Adjusted EBITDA (or EBITDA) to be an alternative to net income as a measure of operating performance or an alternative to cash flows from operating activities as a measure of liquidity or an alternative to any other measure of financial performance presented in accordance with US GAAP. Additionally, we do not intend for Adjusted EBITDA (or EBITDA) to be used as a measure of free cash flow available for management's discretionary use, as the measure excludes certain cash requirements such as interest payments, tax payments and other debt service requirements. Because not all companies use identical calculations, our presentation of Adjusted EBITDA (and EBITDA) may not be comparable to similarly titled measures of other companies.

ii

market heat rate	Heat rate is a measure of the efficiency of converting a fuel source to electricity. Market heat rate is the implied relationship between wholesale electricity prices and natural gas prices and is calculated by dividing the wholesale market price of electricity, which is based on the price offer of the marginal supplier in ERCOT (generally natural gas plants), by the market price of natural gas. Forward wholesale electricity market price quotes in ERCOT are generally limited to two or three years; accordingly, forward market heat rates are generally limited to the same time period. Forecasted market heat rates for time periods for which market price quotes are not available are based on fundamental economic factors and forecasts, including electricity supply, demand growth, capital costs associated with new construction of generation supply, transmission development and other factors.

ENERGY FUTURE COMPETITIVE HOLDINGS COMPANY

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES

Description of Business

References in this report to "we," "our," "us" and "the company" are to EFCH and/or its subsidiaries, as apparent in the context. See "Glossary" for defined terms.

EFCH, a wholly-owned subsidiary of EFH Corp., is a Dallas, Texas-based holding company. We conduct our operations almost entirely through our wholly-owned subsidiary, TCEH. TCEH is a holding company for subsidiaries engaged in competitive electricity market activities largely in Texas, including electricity generation, wholesale energy sales and purchases, commodity risk management and trading activities and retail electricity sales. Key management activities, including commodity risk management and electricity sourcing for our retail and wholesale customers, are performed on an integrated basis; consequently, there are no reportable business segments.

TCEH operates largely in the ERCOT market, and wholesale electricity prices in that market have generally moved with the price of natural gas. Wholesale electricity prices have significant implications to its profitability and cash flows and, accordingly, the value of its business.

Basis of Presentation

The condensed consolidated financial statements have been prepared in accordance with US GAAP and on the same basis as the audited financial statements included in our 2011 Form 10-K. 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. Any acquisitions of outstanding debt for cash, including notes that had been issued in lieu of cash interest, are presented in the financing activities section of the statement of cash flows. 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 our 2011 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 revenue and expense, including fair value measurements. In the event estimates and/or assumptions prove to be different from actual amounts, adjustments are made in subsequent periods to reflect more current information.

4

2. CONSOLIDATION OF VARIABLE INTEREST ENTITIES

A variable interest entity (VIE) is an entity with which we have a relationship or arrangement that indicates some level of control over the entity or results in economic risks to us. Accounting standards require consolidation of a VIE if we have (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 (primary beneficiary). Our VIEs consist of equity investments in certain of our subsidiaries. In determining the appropriateness of consolidation of a VIE, we evaluate its purpose, governance structure, decision making processes and risks that are passed on to its interest holders. We also examine 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.

Consolidated VIEs

See discussion in Note 4 regarding the VIE related to our accounts receivable securitization program that is consolidated under the accounting standards because EFCH (as the owner of TXU Energy) is the primary beneficiary of TXU Receivables Company, which is owned and controlled by our parent, EFH Corp.

We also consolidate Comanche Peak Nuclear Power Company LLC (CPNPC), which was formed by subsidiaries of TCEH and Mitsubishi Heavy Industries Ltd. (MHI) for the purpose of developing two new nuclear generation units at our existing Comanche Peak nuclear-fueled generation facility using MHI's US-Advanced Pressurized Water Reactor technology and to obtain a combined operating license from the NRC. CPNPC is currently financed through capital contributions from the subsidiaries of TCEH and MHI that hold 88% and 12% of CPNPC's equity interests, respectively (see Note 7).

The carrying amounts and classifications of the assets and liabilities related to our consolidated VIEs are as follows:

Assets:	June 30, 2012		December 31, 2011		Liabilities:	June 30, 2012		December 31, 2011
Cash and cash equivalents	$	11	$	10	Short-term borrowings	$	142	$	104
Accounts receivable	544		525		Trade accounts payable	1		1
Property, plant and equipment	138		132		Other current liabilities	10		9
Other assets, including $2 million of current assets in both periods	6		6
Total assets	$	699	$	673	Total liabilities	$	153	$	114

The assets of our consolidated VIEs can only be used to settle the obligations of the VIE, and the creditors of our consolidated VIEs do not have recourse to our assets to settle the obligations of the VIE.

4. TRADE ACCOUNTS RECEIVABLE AND ACCOUNTS RECEIVABLE SECURITIZATION PROGRAM

TCEH participates in an accounts receivable securitization program with financial institutions (the funding entities). Under the program, TXU Energy (originator) sells trade accounts receivable to TXU Receivables Company, which is an entity created for the special purpose of purchasing receivables from the originator and is a wholly-owned, bankruptcy-remote, direct subsidiary of EFH Corp. We consolidate TXU Receivables Company in accordance with consolidation accounting standards as discussed in Note 2. TXU Receivables Company sells undivided interests in the purchased accounts receivable for cash to entities established for this purpose by the funding entities. In accordance with accounting standards, the trade accounts receivable amounts under the program are reported as pledged balances, and the related funding amounts are reported as short-term borrowings.

The maximum funding amount currently available under the program is $350 million. Program funding increased from $104 million at December 31, 2011 to $142 million at June 30, 2012. Under the terms of the program, available funding at June 30, 2012 was reduced by $40 million of customer deposits held by the originator because TCEH's credit ratings were lower than Ba3/BB-.

All new trade receivables under the program generated by the originator are continuously purchased by TXU Receivables Company with the proceeds from collections of receivables previously purchased. Ongoing changes in the amount of funding under the program, through changes in the amount of undivided interests sold by TXU Receivables Company, reflect seasonal variations in the level of accounts receivable, changes in collection trends and other factors such as changes in sales prices and volumes. TXU Receivables Company has issued a subordinated note payable to the originator for the difference between the face amount of the uncollected accounts receivable purchased, less a discount, and cash paid to the originator that was funded by the sale of the undivided interests. The subordinated note issued by TXU Receivables Company is subordinated to the undivided interests of the funding entities in the purchased receivables. The balance of the subordinated note payable, which is eliminated in consolidation, totaled $402 million and $420 million at June 30, 2012 and December 31, 2011, respectively.

The discount from face amount on the purchase of receivables from the originator principally funds program fees paid to the funding entities. The program fees consist primarily of interest costs on the underlying financing and are reported as interest expense and related charges. The discount also funds a servicing fee, which is reported as SG&A expense, paid by TXU Receivables Company to EFH Corporate Services Company (Service Co.), a direct wholly-owned subsidiary of EFH Corp., which provides recordkeeping services and is the collection agent for the program.

Program fee amounts were as follows:

	Three Months Ended June 30,		Six Months Ended June 30,
	2012	2011	2012	2011
Program fees	$2	$2	$4	$4
Program fees as a percentage of average funding (annualized)	7.8%	9.8%	7.4%	8.0%

Activities of TXU Receivables Company were as follows:

	Six Months Ended June 30,
	2012			2011
Cash collections on accounts receivable	$	2,111		$	2,501
Face amount of new receivables purchased	(2,131		)	(2,595		)
Discount from face amount of purchased receivables	5			5
Program fees paid to funding entities	(4		)	(4		)
Servicing fees paid to Service Co. for recordkeeping and collection services	(1		)	(1		)
Increase (decrease) in subordinated notes payable	(18		)	82
Cash flows provided to originator under the program	$	(38	)	$	(12	)

8

The program, which expires in October 2013, may be terminated upon the occurrence of a number of specified events, including if the delinquency ratio (delinquent for 31 days) for the sold receivables, the default ratio (delinquent for 91 days or deemed uncollectible), the dilution ratio (reductions for discounts, disputes and other allowances) or the days outstanding ratio exceed stated thresholds, unless the funding entities waive such events of termination. The thresholds apply to the entire portfolio of sold receivables. In addition, the program may be terminated if TXU Receivables Company or Service Co. defaults in any payment with respect to debt in excess of $50,000 in the aggregate for such entities, or if TCEH, any affiliate of TCEH acting as collection agent other than Service Co., any parent guarantor of the originator or the originator shall default in any payment with respect to debt (other than hedging obligations) in excess of $200 million in the aggregate for such entities. At June 30, 2012, there were no such events of termination.

If the program was terminated, TCEH's liquidity would be reduced because collections of sold receivables would be used by TXU Receivables Company to repurchase the undivided interests from the funding entities instead of purchasing new receivables. We expect that the level of cash flows would normalize in approximately 16 to 30 days following termination.

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 are considered Merger-related debt to the extent the proceeds are used to repurchase Merger-related debt. Merger-related debt of EFH Corp. (parent) that is fully and unconditionally guaranteed on a joint and several basis by EFIH and EFCH (parent entity) is subject to push down in accordance with SEC Staff Accounting Bulletin Topic 5-J, and as a result, a portion of such debt and related interest expense is reflected in our financial statements. Merger-related debt of EFH Corp. held as an investment by its subsidiaries is not subject to push down.

The amount reflected on our balance sheet as pushed down debt ($721 million and $707 million at June 30, 2012 and December 31, 2011, respectively, as shown in the long-term debt table above) represents 50% of the principal amount (plus unamortized premium) of the EFH Corp. Merger-related debt guaranteed by EFCH (parent entity). This percentage reflects the fact that at the time of the Merger, the equity investments of EFCH (parent entity) 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., we record the settlement of such amounts as noncash capital contributions from EFH Corp. (see Note 7).

The tables below present, at June 30, 2012 and December 31, 2011, an analysis of the total outstanding principal amount of EFH Corp. debt that EFCH (parent entity) and EFIH have guaranteed (fully and unconditionally on a joint and several basis), as (i) amounts that EFIH held as an investment, (ii) amounts held by nonaffiliates subject to push down to our balance sheet and (iii) amounts held by nonaffiliates that are not Merger-related. The EFCH (parent entity) guarantee of the EFH Corp. debt is not secured, and the EFIH guarantee of the EFH Corp. Senior Notes is not secured. The EFIH guarantees of the EFH Corp. 10% and 9.75% Notes are secured on an equal and ratable basis by EFIH's pledge of 100% of the membership interests and other investments it owns in Oncor Holdings (the EFIH Collateral).

TCEH Senior Secured Facilities— Borrowings under the TCEH Senior Secured Facilities totaled $20.426 billion at June 30, 2012 and consisted of:

• $3.809 billion of TCEH Term Loan Facilities maturing in October 2014 with interest payable at LIBOR plus 3.50%;

• $15.370 billion of TCEH Term Loan Facilities maturing in October 2017 with interest payable at LIBOR plus 4.50%;

• $42 million of cash borrowed under the TCEH Letter of Credit Facility maturing in October 2014 with interest payable at LIBOR plus 3.50% (see discussion under "Credit Facilities" above);

• $1.020 billion of cash borrowed under the TCEH Letter of Credit Facility maturing in October 2017 with interest payable at LIBOR plus 4.50% (see discussion under "Credit Facilities" above), and

• Amounts borrowed under the TCEH Revolving Credit Facility, which may be reborrowed from time to time until October 2013 with respect to $645 million of commitments and until October 2016 with respect to $1.409 billion of commitments, totaled $58 million and $127 million, respectively, at June 30, 2012.

The TCEH Commodity Collateral Posting Facility, under which there were no borrowings at June 30, 2012, will mature in December 2012.

Each of the loans described above that matures in 2016 or 2017 includes a "springing maturity" provision pursuant to which (i) in the event that more than $500 million aggregate principal amount of the TCEH 10.25% Notes due in 2015 (other than notes held by EFH Corp. or its controlled affiliates at March 31, 2011 to the extent held at the determination date as defined in the Credit Agreement) or more than $150 million aggregate principal amount of the TCEH Toggle Notes due in 2016 (other than notes held by EFH Corp. or its controlled affiliates at March 31, 2011 to the extent held as of the determination date as defined in the Credit Agreement), as applicable, remain outstanding as of 91 days prior to the maturity date of the applicable notes and (ii) TCEH's total debt to Adjusted EBITDA ratio (as defined in the TCEH Senior Secured Facilities) is greater than 6.00 to 1.00 at the applicable determination date, then the maturity date of the extended loans will automatically change to 90 days prior to the maturity date of the applicable notes.

Under the terms of the TCEH Senior Secured Facilities, the commitments of the lenders to make loans to TCEH are several and not joint. Accordingly, if any lender fails to make loans to TCEH, TCEH's available liquidity could be reduced by an amount up to the aggregate amount of such lender's commitments under the TCEH Senior Secured Facilities.

The TCEH Senior Secured Facilities are fully and unconditionally guaranteed jointly and severally on a senior secured basis by EFCH, and subject to certain exceptions, each existing and future direct or indirect wholly-owned US subsidiary of TCEH. The TCEH Senior Secured Facilities, along with the TCEH Senior Secured Notes and certain commodity hedging transactions and the interest rate swaps described under "TCEH Interest Rate Swap Transactions" below, are secured on a first priority basis by (i) substantially all of the current and future assets of TCEH and TCEH's subsidiaries who are guarantors of such facilities and (ii) pledges of the capital stock of TCEH and certain current and future direct or indirect subsidiaries of TCEH.

TCEH 11.5% Senior Secured Notes —At June 30, 2012, the principal amount of the TCEH 11.5% Senior Secured Notes totaled $1.750 billion. The notes mature in October 2020, with interest payable in cash quarterly in arrears on January 1, April 1, July 1 and October 1, at a fixed rate of 11.5% per annum. The notes are fully and unconditionally guaranteed on a joint and several basis by EFCH and each subsidiary of TCEH that guarantees the TCEH Senior Secured Facilities (collectively, the Guarantors). The notes are secured, on a first-priority basis, by security interests in all of the assets of TCEH, and the guarantees are secured on a first-priority basis by all of the assets and equity interests held by the Guarantors, in each case, to the extent such assets and equity interests secure obligations under the TCEH Senior Secured Facilities (the TCEH Collateral), subject to certain exceptions and permitted liens.

The notes were issued in a private placement and are not registered under the Securities Act of 1933, as amended. The notes are (i) senior obligations and rank equally in right of payment with all senior indebtedness of TCEH, (ii) senior in right of payment to all existing or future unsecured and second-priority secured debt of TCEH to the extent of the value of the TCEH Collateral and (iii) senior in right of payment to any future subordinated debt of TCEH. These notes are effectively subordinated to all secured obligations of TCEH that are secured by assets other than the TCEH Collateral, to the extent of the value of the assets securing such obligations.

14

TCEH 15% Senior Secured Second Lien Notes(including Series B)— At June 30, 2012, the principal amount of the TCEH 15% Senior Secured Second Lien Notes totaled $1.571 billion. These notes mature in April 2021, with interest payable in cash quarterly in arrears on January 1, April 1, July 1 and October 1 at a fixed rate of 15% per annum. The notes are fully and unconditionally guaranteed on a joint and several basis by EFCH and, subject to certain exceptions, each subsidiary of TCEH that guarantees the TCEH Senior Secured Credit Facilities. The notes are secured, on a second-priority basis, by security interests in all of the assets of TCEH, and the guarantees (other than the guarantee of EFCH) are secured on a second-priority basis by all of the assets and equity interests of all of the Guarantors other than EFCH (collectively, the Subsidiary Guarantors), in each case, to the extent such assets and security interests secure obligations under the TCEH Senior Secured Credit Facilities on a first-priority basis, subject to certain exceptions (including the elimination of the pledge of equity interests of any Subsidiary Guarantor to the extent that separate financial statements would be required to be filed with the SEC for such Subsidiary Guarantor under Rule 3-16 of Regulation S-X) and permitted liens. The guarantee from EFCH is not secured.

The notes are senior obligations of the issuer and rank equally in right of payment with all senior indebtedness of TCEH, are senior in right of payment to all existing or future unsecured debt of TCEH to the extent of the value of the TCEH Collateral (after taking into account any first-priority liens on the TCEH Collateral) and are senior in right of payment to any future subordinated debt of TCEH. These notes are effectively subordinated to TCEH's obligations under the TCEH Senior Secured Credit Facilities, the TCEH Senior Secured Notes and TCEH's commodity and interest rate hedges that are secured by a first-priority lien on the TCEH Collateral and any future obligations subject to first-priority liens on the TCEH Collateral, to the extent of the value of the TCEH Collateral, and to all secured obligations of TCEH that are secured by assets other than the TCEH Collateral, to the extent of the value of the assets securing such obligations.

TCEH 10.25% Senior Notes (including Series B) and 10.50/11.25% Senior Toggle Notes (collectively, the TCEH Senior Notes)— At June 30, 2012, the principal amount of the TCEH Senior Notes totaled $5.144 billion, including $363 million aggregate principal amount held by EFH Corp. and EFIH, and the notes are fully and unconditionally guaranteed on a joint and several unsecured basis by TCEH's direct parent, EFCH (which owns 100% of TCEH), and by each subsidiary that guarantees the TCEH Senior Secured Facilities. The TCEH 10.25% Notes mature in November 2015, with interest payable in cash semi-annually in arrears on May 1 and November 1 at a fixed rate of 10.25% per annum. The TCEH Toggle Notes mature in November 2016, with interest payable semi-annually in arrears on May 1 and November 1 at a fixed rate of 10.50% per annum for cash interest and at a fixed rate of 11.25% per annum for PIK Interest. For any interest period until November 2012, TCEH may elect to pay interest on the Toggle Notes (i) entirely in cash; (ii) by increasing the principal amount of the notes or by issuing new TCEH Toggle Notes (PIK Interest); or (iii) 50% in cash and 50% in PIK Interest. Once TCEH makes a PIK election, which it did effective with the May 2009 interest payment, the election is valid for each succeeding interest payment period until TCEH revokes the election.

Fair Value of Long-Term Debt

At June 30, 2012 and December 31, 2011, the estimated fair value of our long-term debt (excluding capital leases) totaled $16.164 billion and $18.740 billion, respectively, and the carrying amount totaled $30.524 billion and $30.434 billion, respectively. We determine fair value in accordance with accounting standards as discussed in Note 8 and at June 30, 2012 represents Level 2 valuations. We obtain security pricing from a vendor 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.

TCEHInterest Rate Swap Transactions

TCEH employs interest rate swaps to hedge exposure to its variable rate debt. As reflected in the table below, at June 30, 2012, TCEH has entered into the following series of interest rate swap transactions that effectively fix the interest rates at between 5.5% and 9.3%.

Fixed Rates	Expiration Dates	Notional Amount
5.5% — 9.3%	October 2012 through October 2014	$18.57 billion (a)
6.8% — 9.0%	October 2015 through October 2017	$12.60 billion (b)

___________

(a) Swaps related to an aggregate $1.1 billion principal amount of debt expired in 2012. Per the terms of the transactions, the nominal amount of swaps entered into in 2011 grew by $1.02 billion, substantially offsetting the expired swaps.

(b) These swaps are effective from October 2014 through October 2017. The $12.6 billion notional amount of swaps includes $3 billion that expires in October 2015 and the remainder in October 2017.

15

TCEH has also entered into interest rate basis swap transactions that further reduce the fixed borrowing costs achieved through the interest rate swaps. Basis swaps in effect at June 30, 2012 totaled $18.57 billion notional amount, an increase of $0.8 billion from December 31, 2011 reflecting new and expired swaps. The basis swaps relate to debt outstanding through 2014.

The interest rate swap counterparties, certain of which are parties to master netting agreements, are secured on an equal and ratable basis by the same collateral package granted to the lenders under the TCEH Senior Secured Facilities.

The interest rate swaps have resulted in net losses reported in interest expense and related charges as follows:

	Three Months Ended June 30,						Six Months Ended June 30,
	2012			2011			2012			2011
Realized net loss	$	(168	)	$	(173	)	$	(337	)	$	(333	)
Unrealized net gain (loss)	(107		)	(403		)	4			(261		)
Total	$	(275	)	$	(576	)	$	(333	)	$	(594	)

The cumulative unrealized mark-to-market net liability related to all TCEH interest rate swaps totaled $2.227 billion and $2.231 billion at June 30, 2012 and December 31, 2011, respectively, of which $69 million and $76 million (both pre-tax), respectively, were reported in accumulated other comprehensive income.

6. COMMITMENTS AND CONTINGENCIES

We have entered into contracts that contain guarantees to unaffiliated parties that could require performance or payment under certain conditions. See Note 5 for discussion of guarantees and security for certain of our debt and EFCH guarantees of certain EFH Corp. debt.

Letters of Credit

At June 30, 2012, TCEH had outstanding letters of credit under its credit facilities totaling $866 million as follows:

• $448 million to support risk management and trading margin requirements in the normal course of business, including over-the-counter hedging transactions and collateral postings with ERCOT;

• $208 million to support floating rate pollution control revenue bond debt with an aggregate principal amount of $204 million (the letters of credit are available to fund the payment of such debt obligations and expire in 2014);

• $71 million to support TCEH's REP's financial requirements with the PUCT, and

• $139 million for miscellaneous credit support requirements.

Litigation Related to Generation Facilities

In November 2010, an administrative appeal challenging the decision of the TCEQ to renew and amend Oak Grove Management Company LLC's (Oak Grove) (a wholly-owned subsidiary of TCEH) Texas Pollutant Discharge Elimination System (TPDES) permit related to water discharges was filed by Robertson County: Our Land, Our Lives and Roy Henrichson in the Travis County, Texas District Court. Plaintiffs seek a reversal of the TCEQ's order and a remand back to the TCEQ for further proceedings. In addition to this administrative appeal, in November 2010, two other petitions were filed in Travis County, Texas District Court by Sustainable Energy and Economic Development Coalition and Paul and Lisa Rolke, respectively, who were non-parties to the administrative hearing before the State Office of Administrative Hearings, challenging the TCEQ's decision to renew and amend Oak Grove's TPDES permit and asking the District Court to remand the matter to the TCEQ for further proceedings. In January 2012, the court dismissed the petition filed by Paul and Lisa Rolke, and in March 2012, the court denied the Rolkes' motion for a new trial. Although we cannot predict the outcome of these proceedings, we believe that the renewal and amendment of the Oak Grove TPDES permit by the TCEQ were in accordance with applicable law. There can be no assurance that the outcome of these matters would not result in a material impact on our results of operations, liquidity or financial condition.

In January 2012, the Sierra Club filed a petition in Travis County, Texas District Court challenging the TCEQ's decision to issue permit amendments imposing limits on emissions during planned startup, shutdown and maintenance activities at Luminant's Big Brown, Monticello, Martin Lake and Sandow Unit 4 generation facilities. In July 2012, the Sierra Club voluntarily dismissed its challenge, with prejudice to refiling these claims in state court. Accordingly, this matter has been favorably resolved.

In September 2010, the Sierra Club filed a lawsuit in the US District Court for the Eastern District of Texas (Texarkana Division) against EFH Corp. and Luminant Generation Company LLC (a wholly-owned subsidiary of TCEH) for alleged violations of the Clean Air Act (CAA) at Luminant's Martin Lake generation facility. In May 2012, the Sierra Club filed a lawsuit in the US District Court for the Western District of Texas (Waco Division) against EFH Corp. and Luminant Generation Company LLC for alleged violations of the CAA at Luminant's Big Brown generation facility. While we are unable to estimate any possible loss or predict the outcome, we believe that the Sierra Club's claims are without merit, and we intend to vigorously defend these lawsuits. The litigation related to Martin Lake is currently stayed by the court. In addition, in December 2010 and again in October 2011, the Sierra Club informed Luminant that it may sue Luminant for allegedly violating CAA provisions in connection with Luminant's Monticello generation facility. In May 2012, the Sierra Club informed us that it may sue us for allegedly violating CAA provisions in connection with Luminant's Sandow 4 generation facility. While we cannot predict whether the Sierra Club will actually file suit regarding Monticello or Sandow 4 or the outcome of any resulting proceedings, we believe we have complied with all requirements of the CAA at all of our generation facilities.

See below for discussion of the pending legal challenge of the CSAPR and our motion to stay the effective date of the CSAPR, in each case as applied to Texas.

Regulatory Reviews

In June 2008, the EPA issued an initial request for information to TCEH under the EPA's authority under Section 114 of CAA. The stated purpose of the request is to obtain information necessary to determine compliance with the CAA, including New Source Review Standards and air permits issued by the TCEQ for the Big Brown, Monticello and Martin Lake generation facilities. Historically, as the EPA has pursued its New Source Review enforcement initiative, companies that have received a large and broad request under Section 114, such as the request received by TCEH, have in many instances subsequently received a notice of violation from the EPA, which has in some cases progressed to litigation or settlement. In July 2012, the EPA sent us a notice of violation alleging noncompliance with the CAA's New Source Review Standards and the air permits at our Martin Lake and Big Brown generation facilities. We are evaluating the notice of violation and intend to confer with the EPA regarding the bases for the notice. We continue to believe that we have complied with all requirements of the CAA at all of our generation facilities, but we are unable to predict the outcome of this matter.

Cross-State Air Pollution Rule (CSAPR)

In July 2011, the EPA issued the CSAPR, compliance with which would require significant additional reductions of sulfur dioxide (SO₂) and nitrogen oxides (NO_x) emissions from our fossil-fueled generation units. In August 2011, we petitioned the EPA to reconsider and stay the effectiveness of the CSAPR, in each case as applied to Texas. In September 2011, we filed a petition for review in the U.S. Court of Appeals for the District of Columbia Circuit (D.C. Circuit Court) challenging the CSAPR as it applies to Texas. In that legal proceeding, we also filed a motion to stay the effective date of the CSAPR as applied to Texas. In the absence of a stay, the CSAPR would have caused us to, among other actions, idle two lignite/coal-fueled generation units and cease certain lignite mining operations by the end of 2011.

In December 2011, the D.C. Circuit Court granted our motion and all other motions for a judicial stay of the CSAPR in its entirety, including as applied to Texas. The D.C. Circuit Court's order does not invalidate the CSAPR but stays the implementation of its emissions reduction programs until a final ruling regarding the CSAPR's validity is issued by the D.C. Circuit Court. The D.C. Circuit Court's order states that the EPA is expected to continue administering the CAIR (the predecessor rule to the CSAPR) pending the court's resolution of the petitions for review. Oral argument on the petitions was held in April 2012. We cannot predict when or how the D.C. Circuit Court will rule on the petitions.

In February 2012, the EPA released a final rule (Final Revisions) and a proposed rule revising certain aspects of the CSAPR, including increases in the emissions budgets for Texas and our generation assets as compared to the July 2011 version of the rule. In March 2012, we submitted comments to the EPA on the proposed rule requesting the EPA to make additional corrections to the CSAPR's budgets for Texas. In June 2012, the EPA finalized the proposed rule (Second Revised Rule). As compared to the proposed revisions to the CSAPR issued by the EPA in October 2011, these recent rules finalize emissions budgets for our generation assets that are approximately 6% lower for SO₂, 3% higher for annual NO_x and 2% higher for seasonal NO_x. Because the CSAPR is currently stayed by the D.C. Circuit Court, the Final Revisions and the Second Revised Rule do not impose any immediate requirements on us, the State of Texas, or other affected parties. In April 2012, we filed in the D.C. Circuit Court a petition for review of the Final Revisions on the ground, among others, that the rules do not include all of the budget corrections we requested from the EPA. We cannot predict whether, when, or in what form the CSAPR, the Final Revisions or the Second Revised Rule will take effect.

Other Matters

We are involved in various legal and administrative proceedings in the normal course of business, the ultimate resolutions of which, in the opinion of management, are not anticipated to have a material effect on our results of operations, liquidity or financial condition.

7. EQUITY

Dividend Restrictions

While EFCH has no contractual dividend restrictions, the TCEH Senior Secured Facilities generally restrict TCEH from making any cash distribution to any of its parent companies for the ultimate purpose of making a cash dividend on their common stock unless at the time, and after giving effect to such distribution, TCEH's consolidated total debt (as defined in the TCEH Senior Secured Facilities) to Adjusted EBITDA would be equal to or less than 6.5 to 1.0. At June 30, 2012, the ratio was 8.2 to 1.0.

In addition, the TCEH Senior Secured Facilities and indentures governing the TCEH Senior Notes, TCEH Senior Secured Notes and TCEH Senior Secured Second Lien Notes generally restrict TCEH's ability to make distributions or loans to any of its parent companies, EFCH and EFH Corp., unless such distributions or loans are expressly permitted under the TCEH Senior Secured Facilities and the indentures governing such notes.

Under applicable law, we are prohibited from paying any dividend to the extent that immediately following payment of such dividend, there would be no statutory surplus or we would be insolvent.

Noncontrolling Interests

As discussed in Note 2, we consolidate a joint venture formed in 2009 for the purpose of developing two new nuclear generation units and the VIE related to our accounts receivable securitization program, each of which results in a noncontrolling interests component of equity. Net loss attributable to the noncontrolling interests was immaterial in the six months ended June 30, 2012 and 2011.

8. FAIR VALUE MEASUREMENTS

Accounting standards related to the determination of fair value define fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. We use a "mid-market" valuation convention (the mid-point price between bid and ask prices) as a practical expedient to measure fair value for the majority of our assets and liabilities subject to fair value measurement on a recurring basis. We primarily use the market approach for recurring fair value measurements and use valuation techniques to maximize the use of observable inputs and minimize the use of unobservable inputs.

We categorize our assets and liabilities recorded at fair value based upon the following fair value hierarchy:

• Level 1 valuations use quoted prices in active markets for identical assets or liabilities that are accessible at the measurement date. An active market is a market in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis. Our Level 1 assets and liabilities include exchange-traded commodity contracts. For example, a significant number of our derivatives are NYMEX futures and swaps transacted through clearing brokers for which prices are actively quoted.

• Level 2 valuations use inputs, in the absence of actively quoted market prices, that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include: (a) quoted prices for similar assets or liabilities in active markets, (b) quoted prices for identical or similar assets or liabilities in markets that are not active, (c) inputs other than quoted prices that are observable for the asset or liability such as interest rates and yield curves observable at commonly quoted intervals and (d) inputs that are derived principally from or corroborated by observable market data by correlation or other means. Our Level 2 valuations utilize over-the-counter broker quotes, quoted prices for similar assets or liabilities that are corroborated by correlations or other mathematical means and other valuation inputs. For example, our Level 2 assets and liabilities include forward commodity positions at locations for which over-the-counter broker quotes are available.

• Level 3 valuations use unobservable inputs for the asset or liability. Unobservable inputs are used to the extent observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at the measurement date. We use the most meaningful information available from the market combined with internally developed valuation methodologies to develop our best estimate of fair value. For example, our Level 3 assets and liabilities include certain derivatives whose values are derived from pricing models that utilize multiple inputs to the valuations, including inputs that are not observable or easily corroborated through other means. See further discussion below.

Our valuation policies and procedures are developed, maintained and validated by an EFH Corp. centralized risk management group that reports to the EFH Corp. Chief Financial Officer, who also functions as the Chief Risk Officer. Risk management functions include valuation model validation, risk analytics, risk control, credit risk management and risk reporting.

We utilize several different valuation techniques to measure the fair value of assets and liabilities, relying primarily on the market approach of using prices and other market information for identical and/or comparable assets and liabilities for those items that are measured on a recurring basis. These methods include, among others, the use of broker quotes and statistical relationships between different price curves.

In utilizing broker quotes, we attempt to obtain multiple quotes from brokers that are active in the commodity markets in which we participate (and require at least one quote from two brokers to determine a pricing input as observable); however, not all pricing inputs are quoted by brokers. The number of broker quotes received for certain pricing inputs varies depending on the depth of the trading market, each individual broker's publication policy, recent trading volume trends and various other factors. In addition, for valuation of interest rate swaps, we use a combination of dealer provided market valuations (generally non-binding) and standard rate swap valuation models utilizing month-end interest rate curves.

21

Certain derivatives and financial instruments are valued utilizing option pricing models that take into consideration multiple inputs including commodity prices, volatility factors, discount rates and other inputs. Additionally, when there is not a sufficient amount of observable market data, valuation models are developed that incorporate proprietary views of market factors. Significant unobservable inputs used to develop the valuation models include volatility curves, correlation curves, illiquid pricing locations and credit/non-performance risk assumptions. Those valuation models are generally used in developing long-term forward price curves for certain commodities. We believe the development of such curves is consistent with industry practice; however, the fair value measurements resulting from such curves are classified as Level 3.

The significant unobservable inputs and valuation models are developed by employees trained and experienced in market operations and fair value measurement and validated by the company's risk management group, which also further analyzes any significant changes in Level 3 measurements. Significant changes in the unobservable inputs could result in significant upward or downward changes in the fair value measurement.

With respect to amounts presented in the following fair value hierarchy tables, the fair value measurement of an asset or liability (e.g., a contract) is required to fall in its entirety in one level, based on the lowest level input that is significant to the fair value measurement. Certain assets and liabilities would be classified in Level 2 instead of Level 3 of the hierarchy except for the effects of credit reserves and non-performance risk adjustments, respectively. Assessing the significance of a particular input to the fair value measurement in its entirety requires judgment, considering factors specific to the asset or liability being measured.

At June 30, 2012, assets and liabilities measured at fair value on a recurring basis consisted of the following:

	Level 1		Level 2		Level 3 (a)		Reclassification (b)		Total
Assets:
Commodity contracts	$	377	$	3,281	$	217	$	33	$	3,908

(b) Fair values are determined on a contract basis, but certain contracts result in a current asset and a noncurrent liability, or vice versa, as presented in the balance sheet.

(c) The nuclear decommissioning trust investment is included in the investments line on the balance sheet. See Note 12.

(a) See table below for description of Level 3 assets and liabilities.

(b) Fair values are determined on a contract basis, but certain contracts result in a current asset and a noncurrent liability, or vice versa, as presented in the balance sheet.

(c) The nuclear decommissioning trust investment is included in the investments line on the balance sheet. See Note 12.

In conjunction with ERCOT's transition to a nodal wholesale market structure effective December 2010, we have entered into certain derivative transactions (primarily congestion revenue rights transactions) that are valued at illiquid pricing locations (unobservable inputs), thus requiring classification as Level 3 assets or liabilities.

Commodity contracts consist primarily of natural gas, electricity, fuel oil, uranium and coal derivative instruments entered into for hedging purposes and include physical contracts that have not been designated "normal" purchases or sales. See Note 9 for further discussion regarding the company's use of derivative instruments.

Interest rate swaps include variable-to-fixed rate swap instruments that are economic hedges of interest on long-term debt as well as interest rate basis swaps designed to effectively reduce the hedged borrowing costs. See Note 5 for discussion of interest rate swaps.

Nuclear decommissioning trust assets represent securities held for the purpose of funding the future retirement and decommissioning of the nuclear generation units. These investments include equity, debt and other fixed-income securities consistent with investment rules established by the NRC and the PUCT.

There were no significant transfers between Level 1 and Level 2 of the fair value hierarchy in the three and six months ended June 30, 2012 and 2011. See the table of changes in fair values of Level 3 assets and liabilities below for discussion of transfers between Level 2 and Level 3 in the three and six months ended June 30, 2012 and 2011.

____________

(a) Electricity purchase and sales contracts include wind generation agreements and hedging positions in the ERCOT west region, as well as power contracts, the valuations of which include unobservable inputs related to the hourly shaping of the price curve. Electricity spread options consist of physical electricity call options. Electricity congestion revenue rights contracts consist of forward purchase contracts (swaps and options) used to hedge electricity price differences between settlement points within ERCOT. Coal purchase contracts relate to western (Powder River Basin) coal.

(b) The range of the inputs may be influenced by factors such as time of day, delivery period, season and location.

(c) Based on the historical average annual range of wind generation.

(d) Based on the historical range of forward average monthly ERCOT West Hub prices.

(e) Based on the historical range of forward average hourly ERCOT North Hub prices.

(f) Estimate of the range of probabilities of default based on past experience and the length of the contract as well as our and counterparties' credit ratings.

(g) Estimate of the default recovery rate based on historical corporate rates.

(h) Estimate of the historical range based on forward natural gas and on-peak power prices for the ERCOT hubs most relevant to our spread options.

(i) Based on historical forward price changes.

____________

(a) Settlements reflect reversals of unrealized mark-to-market valuations previously recognized in net income. Purchases and issuances reflect option premiums paid or received.

(b) Includes transfers due to changes in the observability of significant inputs. Transfers in and out occur at the end of each quarter, which is when the assessments are performed. Transfers out during 2012 reflect increased observability of pricing related to certain congestion revenue rights. Transfers in during 2012 were driven by an increase in nonperformance risk adjustments related to a coal purchase contract as well as certain power contracts that include unobservable inputs related to the hourly shaping of the price curve. Transfers out during 2011 were driven by the effect of an increase in option market trading activity on our natural gas collars for 2014. All Level 3 transfers during 2011 and 2012 are in and out of Level 2.

(c) Substantially all changes in values of commodity contracts are reported in the income statement in net gain (loss) from commodity hedging and trading activities. Activity excludes changes in fair value in the month the position settled as well as amounts related to positions entered into and settled in the same month.

9. COMMODITY AND OTHER DERIVATIVE CONTRACTUAL ASSETS AND LIABILITIES

Strategic Use of Derivatives

We transact in derivative instruments, such as options, swaps, futures and forward contracts, primarily to manage commodity price risk and interest rate risk exposure. Our principal activities involving derivatives consist of a commodity hedging program and the hedging of interest costs on our long-term debt. See Note 8 for a discussion of the fair value of all derivatives.

Natural Gas Price Hedging Program — TCEH has a natural gas price hedging program designed to reduce exposure to changes in future electricity prices due to changes in the price of natural gas, thereby hedging future revenues from electricity sales and related cash flows. In ERCOT, the wholesale price of electricity has generally moved with the price of natural gas. Under the program, TCEH has entered into market transactions involving natural gas-related financial instruments and has sold forward natural gas through 2014. These transactions are intended to hedge a portion of electricity price exposure related to expected lignite/coal- and nuclear-fueled generation for this period. Changes in the fair value of the instruments under the natural gas price hedging program are reported in the income statement in net gain (loss) from commodity hedging and trading activities.

Interest Rate Swap Transactions — Interest rate swap agreements are used to reduce exposure to interest rate changes by converting floating-rate debt to fixed rates, thereby hedging future interest costs and related cash flows. Interest rate basis swaps are used to effectively reduce the hedged borrowing costs. Changes in the fair value of the swaps are recorded as unrealized gains and losses in interest expense and related charges. See Note 5 for additional information about interest rate swap agreements.

Other Commodity Hedging and Trading Activity — In addition to the natural gas price hedging program, TCEH enters into derivatives, including electricity, natural gas, fuel oil, uranium and coal instruments, generally for shorter-term hedging purposes. To a limited extent, TCEH also enters into derivative transactions for proprietary trading purposes, principally in natural gas and electricity markets.

Financial Statement Effects of Derivatives

Substantially all derivative contractual assets and liabilities arise from mark-to-market accounting consistent with accounting standards related to derivative instruments and hedging activities. The following tables provide detail of commodity and other derivative contractual assets and liabilities (with the column totals representing the net positions of the contracts) as reported in the balance sheets at June 30, 2012 and December 31, 2011:

June 30, 2012
	Derivative assets					Derivative liabilities

26

At June 30, 2012 and December 31, 2011, there were no derivative positions accounted for as cash flow or fair value hedges.

Margin deposits that contractually offset these derivative instruments are reported separately in the balance sheet and totaled $1.073 billion and $1.006 billion in net liabilities at June 30, 2012 and December 31, 2011, respectively. Reported amounts as presented in the above table do not reflect netting of assets and liabilities with the same counterparties under existing netting arrangements. This presentation can result in significant volatility in derivative assets and liabilities because we may enter into offsetting positions with the same counterparties, resulting in both assets and liabilities, and the underlying commodity prices can change significantly from period to period.

The following table presents the pre-tax effect on net income of derivatives not under hedge accounting, including realized and unrealized effects:

	Three Months Ended June 30,						Six Months Ended June 30,
Derivative (income statement presentation)	2012			2011			2012			2011
Commodity contracts (Net gain (loss) from commodity hedging and trading activities) (a)	$	(133	)	$	189		$	225		$	171
Interest rate swaps (Interest expense and related charges) (b)	(275		)	(576		)	(333		)	(594		)
Net gain (loss)	$	(408	)	$	(387	)	$	(108	)	$	(423	)

_______________

(a) Amount represents changes in fair value of positions in the derivative portfolio during the period, as realized amounts related to positions settled are assumed to equal reversals of previously recorded unrealized amounts.

(b) Includes amounts reported as unrealized mark-to-market net (gain) loss as well as the net effect on interest paid/accrued, both reported in "Interest Expense and Related Charges" (see Note 12).

The following table presents the pre-tax effect on net income and other comprehensive income (OCI) of derivative instruments previously accounted for as cash flow hedges. There were no amounts recognized in OCI in the three or six months ended June 30, 2012or2011.

Derivative type (income statement presentation of loss reclassified	Three Months Ended June 30,						Six Months Ended June 30,
from accumulated OCI into income)	2012			2011			2012			2011
Interest rate swaps (interest expense and related charges)	$	(2	)	$	(7	)	$	(5	)	$	(17	)
Interest rate swaps (depreciation and amortization)	—			—			(1		)	(1		)
Total	$	(2	)	$	(7	)	$	(6	)	$	(18	)

There were no transactions designated as cash flow hedges during the three or six months ended June 30, 2012or2011.

Accumulated other comprehensive income related to cash flow hedges at June 30, 2012 and December 31, 2011 totaled $45 million and $49 million in net losses (after-tax), respectively, substantially all of which relates to interest rate swaps. We expect that $7 million of net losses (after-tax) related to cash flow hedges included in accumulated other comprehensive income at June 30, 2012 will be reclassified into net income during the next twelve months as the related hedged transactions affect net income.

27

Derivative Volumes — The following table presents the gross notional amounts of derivative volumes at June 30, 2012 and December 31, 2011:

	June 30, 2012		December 31, 2011
Derivative type	Notional Volume				Unit of Measure
Interest rate swaps:
Floating/fixed	$	31,172	$	31,255	Million US dollars
Basis (a)	$	18,567	$	19,167	Million US dollars
Natural gas:
Natural gas price hedge forward sales and purchases (b)	1,144		1,602		Million MMBtu
Locational basis swaps	698		728		Million MMBtu
All other	1,838		841		Million MMBtu
Electricity	104,939		105,673		GWh

_______________

(a) The December 31, 2011 amount includes $1.417 billion notional amount of swaps entered into but not effective until February 2012.

(b) Represents gross notional forward sales, purchases and options transactions in the natural gas price hedging program. The net amount of these transactions was approximately 550 million MMBtu and 700 million MMBtu at June 30, 2012 and December 31, 2011, respectively.

(c) Represents gross forward purchases associated with instruments used to hedge price differences between settlement points in the nodal wholesale market design in ERCOT.

Credit Risk-Related Contingent Features of Derivatives

The agreements that govern our derivative instrument transactions may contain certain credit risk-related contingent features that could trigger liquidity requirements in the form of cash collateral, letters of credit or some other form of credit enhancement. Certain of these agreements require the posting of collateral if our credit rating is downgraded by one or more credit rating agencies; however, due to our credit ratings being below investment grade, substantially all of such collateral posting requirements are already effective.

At June 30, 2012 and December 31, 2011, the fair value of liabilities related to derivative instruments under agreements with credit risk-related contingent features that were not fully cash collateralized totaled $789 million and $364 million, respectively. The liquidity exposure associated with these liabilities was reduced by cash and letter of credit postings with the counterparties totaling $202 million and $78 million at June 30, 2012 and December 31, 2011, respectively. If all the credit risk-related contingent features related to these derivatives had been triggered, including cross default provisions, at June 30, 2012 and December 31, 2011, the remaining related liquidity requirement would have totaled $12 million and $7 million, respectively, after reduction for net accounts receivable and derivative assets under netting arrangements.

In addition, certain derivative agreements that are collateralized primarily with liens on certain of our assets include indebtedness cross-default provisions that could result in the settlement of such contracts if there were a failure under other financing arrangements to meet payment terms or to comply with other covenants that could result in the acceleration of such indebtedness. At June 30, 2012 and December 31, 2011, the fair value of derivative liabilities subject to such cross-default provisions, largely related to interest rate swaps, totaled $2.478 billion and $2.651 billion, respectively, before consideration of the amount of assets subject to the liens. No cash collateral or letters of credit were posted with these counterparties at June 30, 2012 or December 31, 2011 to reduce the liquidity exposure. If all the credit risk-related contingent features related to these derivatives, including amounts related to cross-default provisions, had been triggered at June 30, 2012 and December 31, 2011, the remaining related liquidity requirement after reduction for derivative assets under netting arrangements but before consideration of the amount of assets subject to the liens would have totaled $1.151 billion and $1.160 billion, respectively. See Note 5 for a description of other obligations that are supported by liens on certain of our assets.

As discussed immediately above, the aggregate fair values of liabilities under derivative agreements with credit risk-related contingent features, including cross-default provisions, totaled $3.267 billion and $3.015 billion at June 30, 2012 and December 31, 2011, respectively. These amounts are before consideration of cash and letter of credit collateral posted, net accounts receivable and derivative assets under netting arrangements and assets subject to related liens.

28

Some commodity derivative contracts contain credit risk-related contingent features that do not provide for specific amounts to be posted if the features are triggered. These provisions include material adverse change, performance assurance, and other clauses that generally provide counterparties with the right to request additional credit enhancements. The amounts disclosed above exclude credit risk-related contingent features that do not provide for specific amounts or exposure calculations.

Concentrations of Credit Risk Related to Derivatives

TCEH has significant concentrations of credit risk with the counterparties to its derivative contracts. At June 30, 2012, total credit risk exposure to all counterparties related to derivative contracts totaled $4.098 billion (including associated accounts receivable). The net exposure to those counterparties totaled $333 million at June 30, 2012 after taking into effect master netting arrangements, setoff provisions and collateral. The net exposure assuming setoff provisions in the event of default across all EFH Corp. consolidated subsidiaries totaled $188 million. At June 30, 2012, the credit risk exposure to the banking and financial sector represented 87% of the total credit risk exposure, a significant amount of which is related to the natural gas price hedging program, and the largest net exposure to a single counterparty totaled $145 million. Taking into account setoff provisions in the event of a default across all EFH Corp. consolidated subsidiaries, this counterparty exposure would be eliminated.

Exposure to banking and financial sector counterparties is considered to be within an acceptable level of risk tolerance because all of this exposure is with counterparties with investment grade credit ratings. However, this concentration increases the risk that a default by any of these counterparties would have a material effect on our financial condition, results of operations and liquidity. The transactions with these counterparties contain certain provisions that would require the counterparties to post collateral in the event of a material downgrade in their credit rating.

We maintain credit risk policies with regard to our counterparties to minimize overall credit risk. These policies authorize specific risk mitigation tools including, but not limited to, use of standardized master netting contracts and agreements that allow for netting of positive and negative exposures associated with a single counterparty. Credit enhancements such as parent guarantees, letters of credit, surety bonds, liens on assets and margin deposits are also utilized. Prospective material changes in the payment history or financial condition of a counterparty or downgrade of its credit quality result in the reassessment of the credit limit with that counterparty. The process can result in the subsequent reduction of the credit limit or a request for additional financial assurances. An event of default by one or more counterparties could subsequently result in termination-related settlement payments that reduce available liquidity if amounts are owed to the counterparties related to the derivative contracts or delays in receipts of expected settlements if the counterparties owe amounts to us.

10. PENSION AND OTHER POSTRETIREMENT EMPLOYEE BENEFITS (OPEB) PLANS

Our subsidiaries are participating employers in the EFH Retirement Plan, a defined benefit pension plan sponsored by EFH Corp. Our subsidiaries also participate with EFH Corp. and certain other subsidiaries of EFH Corp. to offer certain health care and life insurance benefits to eligible employees and their eligible dependents upon the retirement of such employees. The net allocated pension and OPEB costs applicable to us totaled $11 million and $13 million in the three months ended June 30, 2012 and 2011, respectively, and $21 million and $26 million in the six months ended June 30, 2012 and 2011, respectively.

The discount rates reflected in net pension and OPEB costs in 2012 are 5.00% and 4.95%, respectively. The expected rates of return on pension and OPEB plan assets reflected in the 2012 cost amounts are 7.4% and 6.8%, respectively.

11. RELATED-PARTY TRANSACTIONS

The following represent our significant related-party transactions:

• TCEH's retail operations pay Oncor for services it provides, principally the delivery of electricity. Expenses recorded for these services totaled $238 million and $251 million in the three months ended June 30, 2012 and 2011, respectively, and $465 million and $490 million in the six months ended June 30, 2012 and 2011, respectively. The fees are based on rates regulated by the PUCT that apply to all REPs. The balance sheets at June 30, 2012 and December 31, 2011 reflect amounts due currently to Oncor totaling $149 million and $138 million, respectively, (included in trade accounts and other payables to affiliates) primarily related to these electricity delivery fees.

• Oncor's bankruptcy-remote financing subsidiary has issued securitization bonds to recover generation-related regulatory assets through a transition surcharge to its customers. Oncor's incremental income taxes related to the transition surcharges it collects are being reimbursed by TCEH. Therefore, the balance sheet reflects a noninterest bearing note payable maturing in 2016 to Oncor of $159 million ($42 million current portion included in trade accounts and other payables to affiliates) and $179 million ($41 million current portion included in trade accounts and other payables to affiliates) at June 30, 2012 and December 31, 2011, respectively. TCEH's payments on the note totaled $10 million and $9 million in the three months ended June 30, 2012 and 2011, respectively, and $20 million and $18 million in the six months ended June 30, 2012 and 2011, respectively.

• TCEH reimburses Oncor for interest expense on Oncor's bankruptcy-remote financing subsidiary's securitization bonds. This reimbursement, which is reported as interest expense and paid on a monthly basis, totaled $7 million and $8 million in the three months ended June 30, 2012 and 2011, respectively, and $14 million and $16 million in the six months ended June 30, 2012 and 2011, respectively.

• Notes receivable from EFH Corp. are payable to TCEH on demand and arise from cash loaned for debt principal and interest payments and other general corporate purposes of EFH Corp. At June 30, 2012 and December 31, 2011, the notes consisted of:

	June 30, 2012		December 31, 2011
Note related to debt principal and interest payments (P&I Note)	$	447	$	1,359
Note related to general corporate purposes (SG&A Note)	233		233
Total	$	680	$	1,592

The demand notes are guaranteed by EFIH and EFCH on an unsecured basis. In connection with the amendment to the TCEH Senior Secured Facilities discussed in Note 9 to Financial Statements in our 2011 Form 10-K, $770 million of the SG&A Note was repaid in April 2011. These demand notes have been pledged as collateral under the TCEH Senior Secured Facilities. In February 2012, $950 million of the P&I Note was repaid by EFH Corp. The repayment was funded by a debt issuance at EFIH in February 2012. In connection with the amendment to the TCEH Senior Secured Facilities, $770 million of the SG&A note was repaid in April 2011. The average daily balance of the notes totaled $674 million and $1.345 billion in the three months ended June 30, 2012 and 2011, respectively, and $891 million and $1.636 billion in the six months ended June 30, 2012 and 2011, respectively. The notes carry interest at a rate based on the one-month LIBOR rate plus 5.00%, and interest income related to the notes totaled $9 million and $18 million in the three months ended June 30, 2012 and 2011, respectively, and $24 million and $43 million in the six months ended June 30, 2012 and 2011, respectively. Because EFH Corp. has sufficient liquidity and the intent to repay the notes within the next 12 months, at June 30, 2012, the $680 million balance of demand notes receivable from EFH Corp. is reported as a current asset in the balance sheet.

31

• TCEH had a demand note payable to EFH Corp. totaling $770 million for the period January to April 2011. The proceeds from the note were used to repay borrowings under the TCEH Revolving Credit Facility. The average daily balance of the note in the three and six months ended June 30, 2011 was $26 million and $371 million, respectively. The note carried interest at a rate based on the one-month LIBOR rate plus 3.50%, and interest expense related to this note totaled $1 million and $7 million in the three and six months ended June 30, 2011. In addition, EFCH has a demand note payable to EFH Corp., the proceeds from which were used to repay outstanding debt. The note totaled $65 million and $57 million at June 30, 2012 and December 31, 2011, respectively, and carried interest at a rate based on the one-month LIBOR rate plus 5%. Interest expense related to this note totaled $831 thousand and $557 thousand in the three months ended June 30, 2012 and 2011, respectively, and $1.6 million and $1.1 million in the six months ended June 30, 2012 and 2011, respectively.

• Receivables from affiliates are measured at historical cost and primarily consist of notes receivable for cash loaned to EFH Corp. for debt principal and interest payments and other general corporate purposes of EFH Corp. as discussed above. TCEH reviews economic conditions, counterparty credit scores and historical payment activity to assess the overall collectability of its affiliated receivables. There were no credit loss allowances at June 30, 2012 and December 31, 2011.

• Our subsidiaries pay a subsidiary of EFH Corp. for information technology, financial, accounting and other administrative services at cost. These costs, which are primarily reported in SG&A expenses, totaled $58 million and $51 million in the three months ended June 30, 2012 and 2011, respectively, and $116 million and $100 million in the six months ended June 30, 2012 and 2011, respectively.

• Under Texas regulatory provisions, the trust fund for decommissioning the Comanche Peak nuclear generation facility is funded by a delivery fee surcharge billed to REPs by Oncor and remitted monthly to TCEH, with the intent that the trust fund assets, reported in investments in our balance sheet, will be sufficient to fund the decommissioning liability, reported in noncurrent liabilities in our balance sheet. The delivery fee surcharges remitted to TCEH totaled $4 million in each of the three month periods ended June 30, 2012 and 2011, respectively, and $8 million in each of the six month periods ended June 30, 2012 and 2011, respectively. Income and expenses associated with the trust fund and the decommissioning liability are offset by a net change in the intercompany receivable/payable between Oncor and TCEH, which in turn results in a change in Oncor's net regulatory asset/liability. At June 30, 2012 and December 31, 2011, the excess of the trust fund balance over the decommissioning liability resulted in a payable to Oncor totaling $260 million and $225 million, respectively, included in notes or other liabilities due affiliates in our balance sheet.

• EFH Corp. files consolidated federal income tax and Texas state margin tax returns that include our results; however, under a tax sharing agreement, our federal income tax and Texas margin tax expense and related balance sheet amounts, including income taxes payable to or receivable from EFH Corp., are recorded as if we file our own corporate income tax return. As a result, we had income taxes payable to EFH Corp. of $47 million and $74 million at June 30, 2012 and December 31, 2011, respectively. We made income tax payments to EFH Corp. of $37 million and $19 million in the six months ended June 30, 2012 and 2011, respectively.

• Certain transmission and distribution utilities in Texas have tariffs in place to assure adequate credit worthiness of any REP to support the REP's obligation to collect securitization bond-related (transition) charges on behalf of the utility. Under these tariffs, as a result of TCEH's credit rating being below investment grade, TCEH is required to post collateral support in an amount equal to estimated transition charges over specified time periods. Accordingly, at both June 30, 2012 and December 31, 2011, TCEH had posted letters of credit in the amount of $12 million for the benefit of Oncor.

• 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.

• In 2007, TCEH entered into the TCEH Senior Secured Facilities with syndicates of financial institutions and other lenders. These syndicates included affiliates of GS Capital Partners, which is a member of the Sponsor Group. Affiliates of each member of the Sponsor Group have from time to time engaged in commercial banking transactions with us and/or provided financial advisory services to us, in each case in the normal course of business.

32

• In the six months ended June 30, 2011, fees paid to Goldman related to debt issuances, amendments and extensions totaled $26 million, described as follows: (i) Goldman acted as a joint lead arranger and joint book-runner in the April 2011 amendment and extension of the TCEH Senior Secured Facilities and received fees totaling $17 million and (ii) Goldman acted as a joint book-running manager and initial purchaser in the issuance of $1.750 billion principal amount of TCEH Senior Secured Notes as part of the April 2011 amendment and extension and received fees totaling $9 million. Affiliates of KKR and TPG Management, L.P. served as advisers to these transactions, and each received $5 million as compensation for their services.

• Affiliates of GS Capital Partners are parties to certain commodity and interest rate hedging transactions with us in the normal course of business.

• Affiliates of the Sponsor Group have sold or acquired, and in the future may sell or acquire, debt or debt securities issued by us in open market transactions or through loan syndications.

• As a result of debt repurchase and exchange transactions in 2009 through 2011, EFH Corp. and EFIH held as investments TCEH debt securities as follows (principal amounts):

	June 30, 2012		December 31, 2011
TCEH Senior Notes:
Held by EFH Corp.	$	284	$	284
Held by EFIH	79		79
TCEH Term Loan Facilities:
Held by EFH Corp.	19		19
Total	$	382	$	382

Interest expense on the notes totaled $10 million and $9 million in the three months ended June 30, 2012 and 2011, respectively, and $19 million and $17 million in the six months ended June 30, 2012 and 2011, respectively.

See Notes 5 and 6 for guarantees and push-down of certain EFH Corp. debt and Note 10 for allocation of EFH Corp. pension and OPEB costs to us.

Nuclear Decommissioning Trust — Investments in a trust that will be used to fund the costs to decommission the Comanche Peak nuclear generation plant are carried at fair value. Decommissioning costs are being recovered from Oncor's customers as a delivery fee surcharge over the life of the plant and deposited in the trust fund. Net gains and losses on investments in the trust fund are offset by a corresponding change in receivables from/payables due to Oncor, reflecting changes in Oncor's regulatory asset/liability (see Note 11). A summary of investments in the fund follows:

	June 30, 2012
	Cost (a)		Unrealized gain		Unrealized loss			Fair market value
Debt securities (b)	$	238	$	15	$	(1	)	$	252

____________

(a) Includes realized gains and losses on securities sold.

(b) The investment objective for debt securities is to invest in a diversified tax efficient portfolio with an overall portfolio rating of AA or above as graded by S&P or Aa2 by Moody's. The debt securities are heavily weighted with municipal bonds. The debt securities had an average coupon rate of 4.14% and 4.38% and an average maturity of 6.1 years and 6.3 years at June 30, 2012 and December 31, 2011, respectively.

(c) The investment objective for equity securities is to invest tax efficiently and to match the performance of the S&P 500 Index.

Property, Plant and Equipment

At June 30, 2012 and December 31, 2011, property, plant and equipment of $18.965 billion and $19.218 billion, respectively, is stated net of accumulated depreciation and amortization of $6.141 billion and $5.499 billion, respectively.

Asset Retirement and Mining Reclamation Obligations

These liabilities primarily relate to nuclear generation plant decommissioning, land reclamation related to lignite mining, removal of lignite/coal-fueled plant ash treatment facilities and generation plant asbestos removal and disposal costs. There is no earnings impact with respect to the recognition of the asset retirement costs for nuclear decommissioning, as all costs are recoverable through the regulatory process as part of Oncor's rates.

The following table summarizes the changes to these obligations, reported in other current liabilities and other noncurrent liabilities and deferred credits in the balance sheet, in the six months ended June 30, 2012:

	Nuclear Plant Decommissioning		Mining Land Reclamation and Other			Total
Liability at January 1, 2012	$	348	$	188		$	536

Noncurrent liability at June 30, 2012	$	358	$	108		$	466

Other Noncurrent Liabilities and Deferred Credits

The balance of other noncurrent liabilities and deferred credits consists of the following:

	June 30, 2012		December 31, 2011
Uncertain tax positions (including accrued interest)	$	1,216	$	1,220
Asset retirement and mining reclamation obligations	466		505

The conclusion of all issues contested by EFH Corp. with the US Internal Revenue Service (IRS) from the 1997 through 2002 audit, including Joint Committee review, could occur before the end of 2012. Upon such conclusion, we expect to reduce the liability for uncertain tax positions by approximately $85 million with an offsetting decrease in deferred tax assets that arose largely from previous payments of alternative minimum taxes. Other than these items, we do not expect the total amount of liabilities recorded related to uncertain tax positions will change significantly in the next 12 months.

Unfavorable Purchase and Sales Contracts – The amortization of unfavorable purchase and sales contracts totaled $7 million and $7 million in the three months ended June 30, 2012 and 2011, respectively, and $14 million and $13 million in the six months ended June 30, 2012 and 2011, respectively. See Note 3 for intangible assets related to favorable purchase and sales contracts.

The estimated amortization of unfavorable purchase and sales contracts for each of the next five fiscal years is as follows:

Year	Amount
2012	$	27
2013	$	26
2014	$	25
2015	$	25

13. SUPPLEMENTAL GUARANTOR CONDENSED FINANCIAL INFORMATION

At June 30, 2012, TCEH and TCEH Finance, as Co-Issuers, had outstanding $5.144 billion aggregate principal amount of 10.25% Senior Notes Due 2015, 10.25% Senior Notes due 2015 Series B and Toggle Notes (collectively, the TCEH Senior Notes) and $1.571 billion aggregate principal amount of 15% Senior Secured Second Lien Notes due 2021 and 15% Senior Secured Second Lien Notes due 2021 (Series B) (collectively, the TCEH Senior Secured Second Lien Notes). The TCEH Senior Notes and the TCEH Senior Secured Second Lien Notes are unconditionally guaranteed by EFCH and by each subsidiary (all 100% owned by TCEH) that guarantees the TCEH Senior Secured Facilities (collectively, the Guarantors). The guarantees issued by the Guarantors are full and unconditional, joint and several guarantees of the TCEH Senior Notes and the TCEH Senior Secured Second Lien Notes. The guarantees of the TCEH Senior Notes rank equally with any senior unsecured indebtedness of the Guarantors and rank effectively junior to all of the secured indebtedness of the Guarantors to the extent of the assets securing that indebtedness. The guarantees of the TCEH Senior Secured Second Lien Notes rank equally in right of payment with all senior indebtedness of TCEH, are senior in right of payment to all existing or future unsecured debt of TCEH to the extent of the value of the TCEH Collateral (after taking into account any first-priority liens on the TCEH Collateral) and are senior in right of payment to any future subordinated debt of TCEH. These notes are effectively subordinated to TCEH's obligations under the TCEH Senior Secured Facilities, the TCEH Senior Secured Notes and TCEH's commodity and interest rate hedges that are secured by a first-priority lien on the TCEH Collateral and any future obligations subject to first-priority liens on the TCEH Collateral, to the extent of the value of the TCEH Collateral (see Note 5). All other subsidiaries of EFCH, either direct or indirect, do not guarantee the TCEH Senior Notes or TCEH Senior Secured Second Lien Notes (collectively the Non-Guarantors). The indentures governing the TCEH Senior Notes and the TCEH Senior Secured Second Lien Notes contain certain restrictions, subject to certain exceptions, on EFCH's ability to pay dividends or make investments. See Note 7.

The following tables have been prepared in accordance with Regulation S-X Rule 3-10, "Financial Statements of Guarantors and Issuers of Guaranteed Securities Registered or Being Registered" in order to present the condensed consolidating statements of income and of cash flows of EFCH (Parent), TCEH (Issuer), the Guarantors and the Non-Guarantors in the three and six months ended June 30, 2012 and 2011 and the condensed consolidating balance sheets at June 30, 2012 and December 31, 2011 of the Parent, Issuer, the Guarantors and the Non-Guarantors. Investments in consolidated subsidiaries are accounted for under the equity method. The presentations reflect the application of SEC Staff Accounting Bulletin Topic 5J, "Push Down Basis of Accounting Required in Certain Limited Circumstances," including the effects of the push down of $330 million and $319 million of the EFH Corp. Senior Notes to the Parent at June 30, 2012 and December 31, 2011, respectively, $388 million of the EFH Corp. Senior Secured Notes to the Parent at both June 30, 2012 and December 31, 2011, and the TCEH Senior Notes, TCEH Senior Secured Notes, TCEH Senior Secured Second Lien Notes and TCEH Senior Secured Facilities to the Other Guarantors at June 30, 2012 and December 31, 2011. TCEH Finance's sole function is to be the co-issuer of the certain TCEH debt securities; therefore, it has no other independent assets, liabilities or operations (see Note 5).

EFCH (parent entity) received no dividends/distributions from its consolidated subsidiaries in the three and six months ended June 30, 2012 or 2011.

Item 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of our financial condition and results of operations in the three and six months ended June 30, 2012 and 2011 should be read in conjunction with our consolidated financial statements and the notes to those statements. Unless otherwise noted, disclosures in the following paragraphs related to hedged or estimated generation output and commodity price sensitivities reflect the expected effects on our operations of the currently governing Clean Air Interstate Rule (CAIR). See "Recent EPA Actions" below for discussion of the EPA's Cross-State Air Pollution Rule (CSAPR).

All dollar amounts in the tables in the following discussion and analysis are stated in millions of US dollars unless otherwise indicated.

Business

EFCH, a wholly-owned subsidiary of EFH Corp., is a Dallas, Texas-based holding company. We conduct our operations almost entirely through our wholly-owned subsidiary, TCEH. TCEH is a holding company for subsidiaries engaged in competitive electricity market activities largely in Texas, including electricity generation, wholesale energy sales and purchases, commodity risk management and trading activities and retail electricity sales. Key management activities, including commodity risk management and electricity sourcing for our retail and wholesale customers, are performed on an integrated basis; consequently, there are no reportable business segments.

Significant Activities and Events and Items Influencing Future Performance

Natural Gas Prices and Natural Gas Price Hedging Program— Because wholesale electricity prices in ERCOT have generally moved with natural gas prices, TCEH has a natural gas price hedging program designed to mitigate the effect of natural gas price changes on future electricity prices. Under the program, we have entered into market transactions involving natural gas-related financial instruments, and at June 30, 2012, have effectively sold forward approximately 550 million MMBtu of natural gas (equivalent to the natural gas exposure of approximately 64,000 GWh at an assumed 8.5 market heat rate) at weighted average annual hedge prices ranging from $7.19 per MMBtu to $7.80 per MMBtu. Volumes and hedge values associated with the natural gas price hedging program are inclusive of offsetting purchases entered into to take into account new wholesale and retail electricity sales contracts and avoid over-hedging. This activity results in both commodity contract asset and liability balances pending the maturity and settlement of the offsetting transactions.

The forward natural gas positions in the hedging program, together with forward power sales, have effectively hedged an estimated 96%, 67% and 33% of the price exposure, on a natural gas equivalent basis, related to TCEH's expected generation output for 2012, 2013 and 2014, respectively (assuming an 8.5 market heat rate). The hedges were entered into with the continuing expectation that wholesale electricity prices in ERCOT will generally move with prices of natural gas, which we expect to be the marginal fuel for the purpose of setting electricity prices generally 70% to 90% of the time in the ERCOT market. If the relationship changes in the future, the cash flows targeted under the natural gas price hedging program may not be achieved.

The company has entered into related put and call transactions (referred to as collars), primarily for 2014, that effectively hedge natural gas prices within a range. These transactions represented 27% of the positions in the natural gas price hedging program at June 30, 2012, with the approximate weighted average strike prices under the collars being a floor of $7.80 per MMBtu and a ceiling of $11.75 per MMBtu.

49

The following table summarizes the natural gas positions in the hedging program at June 30, 2012:

	Measure	Balance 2012 (a)	2013	2014	Total
Natural gas hedge volumes (b)	mm MMBtu	~155	~246	~146	~547
Weighted average hedge price (c)	$/MMBtu	~7.32	~7.19	~7.80	—
Weighted average market price (d)	$/MMBtu	2.96	3.58	3.95	—
Realization of hedge gains (e)	$ billions	~$0.8	~$1.0	~$0.6	~$2.4

___________

(a) Balance of 2012 is from July 1, 2012 through December 31, 2012.

(b) Where collars are reflected, the volumes are based on the notional position of the derivatives to represent protection against downward price movements. The notional volumes for collars are approximately 150 million MMBtu, which corresponds to a delta position of approximately 142 million MMBtu in 2014.

(c) Weighted average hedge prices are based on NYMEX Henry Hub prices of forward natural gas sales positions in the natural gas price hedging program (excluding the impact of offsetting purchases for rebalancing). Where collars are reflected, sales price represents the collar floor price.

(d) Based on NYMEX Henry Hub prices.

(e) Based on cumulative unrealized mark-to-market gain at June 30, 2012.

Changes in the fair value of the instruments in the natural gas price hedging program are being recorded as unrealized gains and losses in net gain (loss) from commodity hedging and trading activities in the statement of income, which has and could continue to result in significant volatility in reported net income. Based on the size of the natural gas price hedging program at June 30, 2012, a $1.00/MMBtu change in natural gas prices across the hedged period would result in the recognition of up to approximately $550 million in pretax unrealized mark-to-market gains or losses.

The natural gas price hedging program has resulted in reported net gains (losses) as follows:

	Three Months Ended June 30,						Six Months Ended June 30,
	2012			2011			2012			2011
Realized net gain	$	506		$	282		$	1,019		$	621
Unrealized net loss including reversals of previously recorded amounts related to positions settled	(577		)	(59		)	(705		)	(401		)
Total	$	(71	)	$	223		$	314		$	220

The cumulative unrealized mark-to-market net gain related to positions in the natural gas price hedging program totaled $2.419 billion and $3.124 billion at June 30, 2012 and December 31, 2011, respectively. The decline reflected settlement of maturing positions, partially offset by unrealized gains on open positions due to a decrease in forward natural gas prices.

Given the volatility of natural gas prices, it is not possible to predict future reported unrealized mark-to-market gains or losses and the actual gains or losses that will ultimately be realized upon settlement of the hedge positions in future years. If natural gas prices at settlement are lower than the prices of the hedge positions, the hedges are expected to mitigate the otherwise negative effect on earnings of lower wholesale electricity prices. However, if natural gas prices at settlement are higher than the prices of the hedge positions, the hedges are expected to dampen the otherwise positive effect on earnings of higher wholesale electricity prices and will in this context be viewed as having resulted in an opportunity cost.

50

The significant cumulative unrealized mark-to-market net gain related to positions in the natural gas price hedging program reflects the sustained decline in forward market natural gas prices as presented in the table below. Forward natural gas prices have generally trended downward over the past several years. While the natural gas price hedging program is designed to mitigate the effect on earnings of low wholesale electricity prices, depressed forward natural gas prices are challenging to the long-term profitability of our generation assets. Specifically, these lower natural gas prices and their potential effect on wholesale electricity prices could have a material impact on the overall profitability of our generation assets for periods in which we do not have significant hedge positions.

___________

(a) Based on NYMEX Henry Hub prices.

(b) For March 31, 2012 and June 30, 2012, natural gas prices for 2012 represent the average of forward prices for April through December and July through December, respectively.

At June 30, 2012, approximately 90% of the natural gas price hedging program transactions were directly or indirectly secured by a first-lien interest in TCEH's assets (including the transactions supported by the TCEH Commodity Collateral Posting Facility – see discussion below under "Financial Condition — Liquidity and Capital Resources"), thereby reducing the cash and letter of credit collateral requirements for the hedging program.

The following sensitivity table provides estimates of the potential impact (in $ millions) of movements in natural gas and certain other commodity prices and market heat rates on realized pre-tax earnings for the periods presented. The estimates related to price sensitivity are based on TCEH's unhedged position and forward prices at June 30, 2012, which for natural gas reflects estimates of electricity generation less amounts hedged through the natural gas price hedging program and amounts under existing wholesale and retail sales contracts. On a rolling basis, generally twelve-months, the substantial majority of retail sales under month-to-month arrangements are deemed to be under contract.

	Balance 2012 (a)		2013	2014	2015	2016

(a) Balance of 2012 is from August 1, 2012 through December 31, 2012.

(b) Assumes conversion of electricity positions based on an approximate 8.5 market heat rate with natural gas generally being on the margin 70% to 90% of the time in the ERCOT market (i.e., when coal is forecast to be on the margin, no natural gas position is assumed to be generated).

(c) Based on Houston Ship Channel natural gas prices at June 30, 2012.

Liability Management Program — At June 30, 2012, we had $30.7 billion principal amount of debt outstanding, including short-term borrowings and $718 million pushed down from EFH Corp. EFH Corp. has implemented a liability management program designed to reduce debt and extend debt maturities through debt exchanges, repurchases and extensions.

Amendments to the TCEH Senior Secured Facilities completed in April 2011 resulted in the extension of $16.4 billion in loan maturities under the TCEH Term Loan Facilities and the TCEH Letter of Credit Facility from October 2014 to October 2017 and $1.4 billion of commitments under the TCEH Revolving Credit Facility from October 2013 to October 2016.

Other liability management activities in 2010 through June 30, 2012 related to TCEH debt include debt exchange, issuance and repurchase activities as follows (all transactions occurred prior to 2012):

Security (except where noted, debt amounts are principal amounts)	Debt Acquired		Debt Issued/Cash Paid
TCEH 10.25% Notes due 2015	$	1,513	$	—
TCEH Toggle Notes due 2016	758		—
TCEH Senior Secured Facilities due 2013 and 2014	1,604		—
TCEH 15% Notes due 2021	—		1,221
TCEH 11.5% Notes due 2020 (a)	—		1,604
Cash paid, including use of proceeds from debt issuances in 2010 (b)	—		343
Total	$	3,875	$	3,168

____________

(a) Excludes from the $1.750 billion principal amount $12 million in debt discount and $134 million in proceeds used for transaction costs related to the issuance of these notes and the amendment and extension of the TCEH Senior Secured Facilities. All other proceeds were used to repay borrowings under the TCEH Senior Secured Facilities, and the remaining transaction costs were funded with cash on hand.

(b) Includes $343 million of the proceeds from the October 2010 issuance of $350 million principal amount of TCEH 15% Senior Secured Second Lien Notes due 2021 that were used to repurchase debt, including $53 million used to repurchase debt held by EFH Corp.

Since inception, TCEH's transactions in the liability management program resulted in the capture of approximately $700 million of debt discount and the extension of approximately $19.6 billion of debt maturities to 2017-2021. Also, see Note 5to Financial Statements.

TCEHInterest Rate Swap Transactions — TCEH employs interest rate swaps to hedge exposure to its variable rate debt. As reflected in the table below, at June 30, 2012, TCEH has entered into the following series of interest rate swap transactions that effectively fix the interest rates at between 5.5% and 9.3%.

Fixed Rates	Expiration Dates	Notional Amount
5.5% — 9.3%	October 2012 through October 2014	$18.57 billion (a)
6.8% — 9.0%	October 2015 through October 2017	$12.60 billion (b)

___________

(a) Swaps related to an aggregate $1.1 billion principal amount of debt expired in 2012. Per the terms of the transactions, the notional amount of swaps entered into in 2011 grew by $1.02 billion, substantially offsetting the expired swaps.

(b) These swaps are effective from October 2014 through October 2017. The $12.6 billion notional amount of swaps includes $3 billion that expires in October 2015 and the remainder in October 2017.

We may enter into additional interest rate hedges from time to time.

TCEH has also entered into interest rate basis swap transactions that further reduce the fixed borrowing costs achieved through the interest rate swaps. Basis swaps in effect at June 30, 2012 totaled $18.57 billion notional amount, an increase of $0.8 billion from December 31, 2011 reflecting new and expired swaps. The basis swaps relate to debt outstanding through 2014.

52

The interest rate swaps have resulted in net losses reported in interest expense and related charges as follows:

	Three Months Ended June 30,						Six Months Ended June 30,
	2012			2011			2012			2011
Realized net loss	$	(168	)	$	(173	)	$	(337	)	$	(333	)
Unrealized net gain (loss)	(107		)	(403		)	4			(261		)
Total	$	(275	)	$	(576	)	$	(333	)	$	(594	)

The cumulative unrealized mark-to-market net liability related to all TCEH interest rate swaps totaled $2.227 billion and $2.231 billion at June 30, 2012 and December 31, 2011, respectively, of which $69 million and $76 million (both pre-tax), respectively, were reported in accumulated other comprehensive income. These fair values can change materially as market conditions change, which could result in significant volatility in reported net income. For example, at June 30, 2012, a one percent change in interest rates would result in an increase or decrease of approximately $800 million in our cumulative unrealized mark-to-market net liability.

Financial Services Reform Legislation —In July 2010, the US Congress enacted financial reform legislation known as the Dodd-Frank Wall Street Reform and Consumer Protection Act (the Financial Reform Act). The primary purposes of the Financial Reform Act are, among other things: to address systemic risk in the financial system; to establish a Bureau of Consumer Financial Protection with broad powers to enforce consumer protection laws and promulgate rules against unfair, deceptive or abusive practices; to enhance regulation of the derivatives markets, including the requirement for central clearing of over-the-counter derivative instruments and additional capital and margin requirements for certain derivative market participants and to implement a number of new corporate governance requirements for companies with listed or, in some cases, publicly-traded securities. While the legislation is broad and detailed, substantial portions of the legislation are currently under rulemakings by federal governmental agencies to implement the standards set out in the legislation and adopt new standards.

Title VII of the Financial Reform Act provides for the regulation of the over-the-counter (OTC) derivatives (Swaps) market. The Financial Reform Act generally requires OTC derivatives (including the types of asset-backed OTC derivatives that we use to hedge risks associated with commodity and interest rate exposure) to be cleared by a derivatives clearing organization. However, under the end-user clearing exemption, entities are exempt from these clearing requirements if they (i) are not "Swap Dealers" or "Major Swap Participants" as defined and (ii) use the Swaps to hedge or mitigate commercial risk. Existing swaps are grandfathered from the clearing requirements. The legislation mandates significant compliance requirements for any entity that is determined to be a Swap Dealer or Major Swap Participant.

In May 2012, the US Commodity Futures Trading Commission (CFTC) published its final rule defining Swap Dealer and Major Swap Participant. Additionally, in July 2012, the CFTC approved the final rules defining the term Swap and the end-user clearing exemption, but has not published the rules, which are an integral part of determining whether an entity is a Swap Dealer or Major Swap Participant. We are currently analyzing and assessing these final rules and their impacts to our results of operations, liquidity and financial condition.

The Financial Reform Act also requires the posting of cash collateral for uncleared swaps. Because these cash collateral requirements are unclear as to whether an end-user or its counterparty (e.g., swap dealer) is required to post cash collateral, there is a risk that the cash collateral requirement could be used to effectively negate the end-user clearing exemption. However, the legislative history of the Financial Reform Act suggests that it was not Congress' intent to require end-users to post cash collateral with respect to swaps. If we were required to post cash collateral on our swap transactions with swap dealers, our liquidity would likely be materially impacted, and our ability to enter into OTC derivatives to hedge our commodity and interest rate risks would be significantly limited.

We cannot predict the outcome of the rulemakings to implement the OTC derivative market provisions of the Financial Reform Act. These rulemakings could negatively affect our ability to hedge our commodity and interest rate risks. Accordingly, we (and other market participants) continue to closely monitor the rulemakings and any other potential legislative and regulatory changes and work with regulators and legislators.

Recent EPA Actions — Cross-State Air Pollution Rule— In 2005, the EPA issued a final rule (the Clean Air Interstate Rule or CAIR) intended to implement the provisions of the Clean Air Act Section 110(a)(2)(D)(i)(I) (CAA Section 110) requiring states to reduce emissions of sulfur dioxide (SO₂) and nitrogen oxides (NO_x) that significantly contribute to other states failing to attain or maintain compliance with the EPA's National Ambient Air Quality Standards (NAAQS) for fine particulate matter and/or ozone. In 2008, the US Court of Appeals for the District of Columbia Circuit (D.C. Circuit Court) invalidated CAIR, but allowed the rule to continue until the EPA issued a final replacement rule. In August 2010, the EPA issued for comment a proposed replacement rule for CAIR called the Clean Air Transport Rule (CATR), similarly intended to implement CAA Section 110. As proposed, the CATR did not include Texas in its annual SO₂ or NO_x programs to address alleged downwind fine particulate matter effects.

In July 2011, the EPA issued the final replacement rule for CAIR (as finally issued, the Cross-State Air Pollution Rule (CSAPR)). Unlike the CATR, the CSAPR includes Texas in its annual SO₂ and NO_x emissions reduction programs, as well as the seasonal NO_x emissions reduction program. These programs require significant additional reductions of SO₂ and NO_x emissions from fossil-fueled generation units in covered states (including Texas) and institute a limited "cap and trade" system as an additional compliance tool to achieve reductions the EPA contends are necessary to implement CAA Section 110. As adopted in July 2011, the CSAPR would have required our fossil-fueled generation units to (i) reduce their annual SO₂ and NO_x emissions by approximately 137,000 tons (64 percent) and 9,200 tons (22 percent), respectively (compared to 2010 actual levels), each beginning on January 1, 2012 and (ii) reduce their seasonal NO_x emissions by approximately 3,400 tons (19 percent) (compared to 2010 actual levels) beginning on May 1, 2012, which is the start of the ozone season.

In September 2011, we filed a petition for review in the D.C. Circuit Court challenging the CSAPR and a motion to stay the effective date of the CSAPR, in each case as applied to Texas.

In December 2011, the D.C. Circuit Court granted our motion and all other motions for a judicial stay of the CSAPR in its entirety, including as applied to Texas. The D.C. Circuit Court's order does not invalidate the CSAPR but stays the implementation of its emissions reduction programs until a final ruling regarding the CSAPR's validity is issued by the D.C. Circuit Court. The D.C. Circuit Court's order states that the EPA is expected to continue administering the CAIR pending the court's resolution of the petitions for review. Oral argument on the petitions was heard in April 2012. We cannot predict when or how the D.C. Circuit Court will rule on the petitions.

In February 2012, the EPA released a final rule (Final Revisions) and a proposed rule revising certain aspects of the CSAPR, including emissions budgets for the State of Texas. In March 2012, we submitted comments to the EPA on the proposed rule requesting the EPA to make additional corrections to the CSAPR's budgets for Texas. In June 2012, the EPA finalized the proposed rule (Second Revised Rule). The Final Revisions increase the emissions budgets for the State of Texas by 50,517 tons for the annual SO₂ program and 1,375 tons for each of the annual NO_x and seasonal NO_x programs. The Second Revised Rule further increases (over the Final Revisions) the Texas annual NO_x emissions budget by 2,731 tons and the seasonal NO_x emissions budget by 1,142 tons. In total, the emissions budgets established by the Final Revisions along with the Second Revised Rule would require our fossil-fueled generation units to reduce (i) their annual SO₂ and NO_x emissions by approximately 120,600 tons (56 percent) and 9,000 tons (22 percent), respectively, compared to 2010 actual levels, and (ii) their seasonal NO_x emissions by approximately 3,300 tons (18 percent) compared to 2010 levels. The company could comply with these emissions limits either through physical reductions or through the purchase of emissions credits from third parties, but the volume of SO₂ credits that may be purchased from sources outside of Texas is subject to limitations starting in 2014, as described in our 2011 Form 10-K. Because the CSAPR is currently stayed by the D.C. Circuit Court, the Final Revisions and the Second Revised Rule do not impose any immediate requirements on us, the State of Texas, or other affected parties. In April 2012, we filed in the D.C. Circuit Court a petition for review of the Final Revisions on the ground, among others, that the rules do not include all of the budget corrections we requested from the EPA. We cannot predict whether, when, or in what form the CSAPR, the Final Revisions or the Second Revised Rule will take effect. Accordingly, we are unable to predict their effects on our results of operations, liquidity or financial condition.

Mercury and Air Toxics Standard — In 2005, the EPA published a final rule requiring reductions of mercury emissions from lignite/coal-fueled generation plants. The Clean Air Mercury Rule (CAMR) was based on a nationwide cap and trade approach. The mercury reductions were required to be phased in between 2010 and 2018. In March 2008, the D.C. Circuit Court vacated CAMR. In February 2009, the US Supreme Court refused to hear the appeal of the D.C. Circuit Court's ruling. In December 2011, the EPA finalized a new rule (called the Mercury and Air Toxics Standard or MATS). MATS regulates the emissions of mercury, nonmercury metals, hazardous organic compounds and acid gases. Any additional control equipment retrofits on our lignite/coal-fueled generation units required to comply with MATS as finalized would need to be installed within three to four years from the April 2012 effective date of the rule. We continue to evaluate the measures necessary to comply with MATS, which are expected to require substantial capital expenditures, and have not finalized cost estimates. In April 2012, we filed a petition for review of MATS in the D.C. Circuit Court. Certain states and industry participants have also filed petitions for review in the D.C. Circuit Court. We cannot predict the timing or outcome of these petitions.

State Implementation Plan —In September 2010, the EPA disapproved a portion of the State Implementation Plan pursuant to which the TCEQ implements its program to achieve the requirements of the Clean Air Act. The EPA disapproved the Texas standard permit for pollution control projects. We hold several permits issued pursuant to the TCEQ standard permit conditions for pollution control projects. We challenged the EPA's disapproval by filing a lawsuit in the US Court of Appeals for the Fifth Circuit (Fifth Circuit Court) arguing that the TCEQ's adoption of the standard permit conditions for pollution control projects was consistent with the Clean Air Act. In March 2012, the Fifth Circuit Court vacated the EPA's disapproval of the Texas standard permit for pollution control projects and remanded the matter to the EPA forreconsideration. We cannot predict the timing or outcome of the EPA's reconsideration.

Regional Haze — SO2 and NOx reductions required under the proposed regional haze/visibility rule (or so-called BART rule) only apply to units built between 1962 and 1977. The reductions are required on a unit-by-unit basis. In February 2009, the TCEQ submitted a State Implementation Plan (SIP) concerning regional haze to the EPA, which we believe will not have a material impact on our generation facilities. In December 2011, the EPA proposed a limited disapproval of the SIP and a Federal Implementation Plan for Texas providing that the inclusion in the CSAPR programs meets the regional haze requirements for SO2 and NOx reductions. In June 2012, the EPA finalized the limited disapproval of the Texas regional haze SIP, but did not finalize a Federal Implementation Plan for Texas. We cannot predict whether or when EPA will finalize a Federal Implementation Plan for Texas regarding regional haze or its impact on our results of operations, liquidity or financial condition.

Greenhouse Gas Emissions — In March 2012, the EPA released a proposal for a performance standard for greenhouse gas emissions from new electric generation units (EGUs). The proposal, which is currently limited to new sources, is based on the carbon dioxide emission rate from a natural gas-fueled combined cycle EGU. None of our existing generation units would be considered a new source under the proposed rule. While we do not believe the proposed rule, as released, affects our existing generation units, we continue to monitor the proposed rule and provided comments on it to the EPA.

In December 2010, the EPA adopted a rule to take over the issuance of permits for greenhouse gas (GHG) emissions from the TCEQ. The State of Texas challenged that rule and the GHG permitting rules through litigation and has refused to implement the GHG permitting rules issued by the EPA. In June 2012, the D.C. Circuit Court upheld all of the EPA's GHG rules and regulations. A number of members of the US Congress from both parties have introduced legislation to either block or delay EPA regulation of GHGs under the Clean Air Act, and legislative activity in this area in the future is possible.

Recent PUCT/ERCOT Actions — In response to ERCOT's publication of reports (known as the Capacity, Demand, and Reserves report and the Seasonal Assessment of Resource Adequacy report) showing declining reserve margins in ERCOT, the PUCT and the ERCOT Board of Directors have taken action to implement or approve in 2012 several changes to ERCOT protocols designed to establish minimum offer floors for wholesale power offers during deployment of certain reliability-related services, including non-spinning reserve, responsive reserve, reliability unit commitment, and other services. In addition, in April 2012 the PUCT proposed a rule that would, among other things, increase the system-wide offer cap that applies to wholesale power offers in ERCOT beginning in 2013 and continuing through 2015. The proposed rule would increase the cap from its present level of $3,000 per MWh to $5,000, $7,000, and $9,000 per MWh in the summers of 2013, 2014, and 2015, respectively, for the stated purpose of sending appropriate price signals to encourage development of generation resources in ERCOT. In June 2012, the PUCT approved a separate rule that will increase the cap from its present level of $3,000 per MWh to $4,500 per MWh effective August 1, 2012. Also in June 2012, the Brattle Group, an independent consultant engaged by ERCOT to assess the incentives for generation investment in the ERCOT market, issued a report on potential next steps for addressing generation resource adequacy. The Brattle report discusses a range of potential solutions that could promote resource adequacy in the ERCOT market, ranging from enhancing the current energy-only structure in ERCOT to creating a capacity market structure, whereby generators receive capacity payments to ensure available generation in the market and provide a return on the generator's investment, similar to those used in certain other competitive markets in the US. The Brattle report concluded that, even if the wholesale energy offer cap were increased to $9,000 per MWh, the expected corresponding reserve margin that would be obtained in the current energy-only market design would be approximately 10%. ERCOT's current target reserve margin is 13.75%. Discussions are ongoing among ERCOT, the PUCT, market participants and other stakeholders regarding actions necessary to continue providing reliable electricity supply in ERCOT.

Summary—We cannot predict future regulatory or legislative actions or any changes in economic and securities market conditions. Such actions or changes could significantly affect our results of operations, liquidity or financial condition.

Financial Results — Three Months Ended June 30, 2012 Compared to Three Months Ended June 30, 2011

Operating revenues decreased $294 million, or 18%, to $1.385 billion in 2012.

Retail electricity revenues decreased $194 million, or 15%, to $1.136 billion due to a 13% decline in sales volumes reflecting decreases in both the business and residential markets. A 17% decline in business market volumes reflected a change in customer mix as well as lower customer counts driven by competitive activity. Residential volumes declined 10% reflecting milder weather and an 7.5% decline in customer count driven by competitive activity. Overall average retail pricing declined 2%.

Wholesale electricity revenues decreased $91 million, or 32%, to $194 million in 2012 reflecting lower generation volumes, due primarily to generation facility outages and economic backdown as well as milder weather. The decline also reflected lower wholesale electricity prices, which were largely due to the effects of lower natural gas prices and milder weather.

Fuel, purchased power costs and delivery fees decreased $164 million, or 20%, to $674 million in 2012. Lignite/coal fuel costs decreased $77 million driven by an increase in planned and unplanned generation unit outages and economic backdown. Delivery fees declined $34 million reflecting lower retail volumes. Purchased power and other costs decreased $17 million reflecting a 35% decrease in volumes purchased driven by lower volumes purchased for resale due to a plant outage and lower wind power generation volumes. Natural gas fuel costs decreased $15 million reflecting lower prices and volumes. Amortization of intangible assets decreased $19 million reflecting lower amortization of emission allowances due to an impairment recorded in the third quarter 2011 and expiration of contracts fair-valued under purchase accounting at the Merger date.

A 31% decrease in lignite/coal-fueled production was driven by the increased generation unit outages and economic backdown, while nuclear-fueled production increased 18% reflecting a spring refueling outage in 2011.

Following is an analysis of amounts reported as net gain (loss) from commodity hedging and trading activities, which totaled $136 million in net losses for the three months ended June 30, 2012 and $190 million in net gains for the three months ended June 30, 2011, which reflects the natural gas price hedging program discussed above under "Natural Gas Prices and Natural Gas Price Hedging Program":

	Three Months Ended June 30, 2012
	Net Realized Gains (Losses)			Net Unrealized Gains (Losses)			Total
Hedging positions	$	482		$	(640	)	$	(158	)
Trading positions	(5		)	27			22
Total	$	477		$	(613	)	$	(136	)

	Three Months Ended June 30, 2011
	Net Realized Gains		Net Unrealized Gains (Losses)			Total
Hedging positions	$	260	$	(74	)	$	186
Trading positions	3		1			4
Total	$	263	$	(73	)	$	190

Unrealized gains and losses that are related to physical derivative commodity contracts and are reported as revenues and purchased power costs, as required by accounting rules, totaled $4 million in net gains in 2011 (as discussed in footnote (b) to the "Revenue and Commodity Hedging and Trading Activities" table above).

Operating costs decreased $19 million, or 8%, to $228 million in 2012. The decrease reflected $29 million in lower nuclear generation maintenance costs reflecting activities performed during the planned refueling outage in 2011 and the absence of a spring refueling outage in 2012, partially offset by $10 million in higher lignite-fueled generation maintenance costs in 2012 reflecting more planned and unplanned outage days.

Depreciation and amortization decreased $30 million, or 8%, to $334 million in 2012. The decrease reflected increased useful lives and retirements of certain generation assets.

60

SG&A expenses decreased $19 million, or 11%, to $156 million in 2012. The decrease reflected $6 million in lower bad debt expense due to improved collection and customer care processes, customer mix and lower revenues, $5 million in lower employee compensation and benefits and $5 million in lower retail marketing and related expense.

Other income totaled $7 million in 2012 and $4 million in 2011. Other income in 2012 included a $6 million fee received to novate certain hedge transactions between counterparties. See Note 12 to Financial Statements.

Other deductions totaled $4 million in 2012 and $89 million in 2011. Other deductions in 2011 included $86 million in third party fees related to the amendment and extension of the TCEH Senior Secured Facilities. See Note 12 to Financial Statements.

Interest income decreased $9 million to $9 million in 2012 reflecting lower balances of notes receivable from EFH Corp. (see Note 11 to Financial Statements).

Interest expense and related charges decreased $317 million, or 27%, to $855 million in 2012. The decrease reflected $296 million lower unrealized mark-to-market net losses on interest rate swaps and $16 million lower amortization of debt issuance costs and discounts.

Income tax benefit totaled $342 million and $349 million on pretax losses in 2012 and 2011, respectively. The effective rate was 34.1% and 34.4% in 2012 and 2011, respectively. The decrease in the effective rate reflects the absence in 2012 of the domestic production deduction, due to a pre-tax loss projected for 2012, largely offset by the higher Texas margin tax expense in 2011 due to the taxable gain arising from the amendments to the TCEH Senior Secured Facilities completed in April 2011.

After-tax loss decreased $6 million to $661 million in 2012 reflecting lower interest expense in 2012 largely offset by net losses from commodity hedging and trading activities in 2012 compared to net gains in 2011.

61

Financial Results — Six Months Ended June 30, 2012 Compared to Six Months Ended June 30, 2011

Operating revenues decreased $744 million, or 22%, to $2.607 billion in 2012.

Retail electricity revenues decreased $470 million, or 19%, to $2.063 billion due to an 18% decline in sales volumes reflecting decreases in both the business and residential markets. A 21% decline in business market volumes reflected a change in customer mix and lower average customer counts driven by competitive activity. Residential volumes declined 16% reflecting milder weather and an 7.5% decrease in customer counts driven by competitive activity. Milder weather drove an 8% decline in average volume per residential customer. Overall average retail pricing was essentially flat to 2011.

Wholesale electricity revenues decreased $256 million, or 38%, to $424 million in 2012 reflecting lower generation volumes, due primarily to generation facility outages and economic backdown as well as milder weather. The decline also reflected lower wholesale electricity prices, which were largely due to the effect of lower natural gas prices and milder weather.

Fuel, purchased power costs and delivery fees decreased $366 million, or 22%, to $1.302 billion in 2012. Lignite/coal fuel costs decreased $138 million reflecting an increase in planned and unplanned generation unit outages and economic backdown. Purchased power and other costs decreased $61 million reflecting the severe winter storm in February 2011, which resulted in equipment failures and higher electricity demand, as well as lower volumes purchased for resale due to a plant outage and lower wind power generation volumes. Natural gas fuel costs decreased $34 million reflecting lower prices and volumes. Delivery fees declined $80 million reflecting lower retail volumes. Amortization of intangibles decreased $42 million reflecting lower amortization of emission allowances due to an impairment recorded in the third quarter 2011 and expiration of contracts fair-valued under purchase accounting at the Merger date.

A 28% decrease in lignite/coal-fueled production was driven by the increased generation unit outages and economic backdown, while nuclear-fueled production increased 9% reflecting a spring refueling outage in 2011.

Following is an analysis of amounts reported as net gain (loss) from commodity hedging and trading activities, which totaled $232 million and $95 million in net gains for the six months ended June 30, 2012 and 2011, respectively, which reflects the natural gas price hedging program discussed above under "Natural Gas Prices and Natural Gas Price Hedging Program":

Unrealized gains and losses that are related to physical derivative commodity contracts and are reported as revenues and purchased power costs, as required by accounting rules, totaled $1 million and $10 million in net gains in 2012 and 2011, respectively (as discussed in footnote (b) to the "Revenue and Commodity Hedging and Trading Activities" table above).

Operating costs decreased $28 million, or 6%, to $435 million in 2012. The decrease reflected $32 million in lower nuclear generation maintenance costs reflecting activities performed during the planned refueling outage in 2011 and the absence of a spring refueling outage in 2012 and $6 million in lower costs related to new systems implementation and process improvements at generation facilities, partially offset by $13 million in higher lignite-fueled generation maintenance costs in 2012 reflecting more planned and unplanned outage days.

Depreciation and amortization decreased $63 million, or 9%, to $663 million in 2012. The decrease reflected increased useful lives and retirements of certain generation assets.

62

SG&A expenses decreased $25 million, or 7%, to $311 million in 2012. The decrease reflected $14 million in lower bad debt expense due to improved collection and customer care processes, customer mix and lower revenues and $8 million in lower retail marketing and related expense.

Other income totaled $10 million in 2012 and $40 million in 2011. Other income in 2012 included a $6 million fee received to novate certain hedge transactions between counterparties. Other income in 2011 included $21 million related to the settlement of bankruptcy claims against a counterparty and $7 million for a property damage claim. See Note 12 to Financial Statements.

Other deductions totaled $7 million in 2012 and $90 million in 2011. Other deductions in 2011 included $86 million in third party fees related to the amendment and extension of the TCEH Senior Secured Facilities. See Note 12 to Financial Statements.

Interest income decreased $21 million to $25 million in 2012 reflecting lower balances of notes receivable from EFH Corp. (see Note 11 to Financial Statements).

Interest expense and related charges decreased $203 million, or 12%, to $1.498 billion in 2012. The decrease reflected a $265 million net improvement in unrealized mark-to-market valuations of interest rate swaps, partially offset by a $75 million increase in interest paid/accrued reflecting debt exchanges and amendments completed in 2011. See Note 12 to Financial Statements.

Income tax benefit totaled $464 million and $512 million on pretax losses in 2012 and 2011, respectively. The effective rate was 33.7% and 34.3% in 2012 and 2011, respectively. The decrease in the effective rate reflects the absence in 2012 of the domestic production deduction, due to a pre-tax loss projected for 2012, largely offset by the higher Texas margin tax expense in 2011 due to the taxable gain arising from the amendments to the TCEH Senior Secured Facilities completed in April 2011.

After-tax loss decreased $68 million to $914 million in 2012 reflecting lower interest expense and higher net gains from commodity hedging and trading activities, partially offset by the effects of milder weather.

Energy-Related Commodity Contracts and Mark-to-Market Activities

The table below summarizes the changes in commodity contract assets and liabilities in the six months ended June 30, 2012 and 2011. The net change in these assets and liabilities, excluding "other activity" as described below, reflects $765 million and $385 million in unrealized net losses in 2012 and 2011, respectively, arising from mark-to-market accounting for positions in the commodity contract portfolio. The portfolio consists primarily of economic hedges but also includes trading positions.

	Six Months Ended June 30,
	2012			2011
Commodity contract net asset at beginning of period	$	3,190		$	3,097
Settlements of positions (a)	(990		)	(556		)

Other activity (c)	(31		)	37
Commodity contract net asset at end of period	$	2,394		$	2,749

____________

(a) Represents reversals of previously recognized unrealized gains and losses upon settlement (offsets realized gains and losses recognized in the settlement period). Excludes changes in fair value in the month the position settled as well as amounts related to positions entered into and settled in the same month.

(b) Represents unrealized net gains recognized, including net gains related to positions in the natural gas price hedging program (see discussion above under "Natural Gas Prices and Natural Gas Price Hedging Program"), partially offset by net losses related to other hedging positions. Excludes changes in fair value in the month the position settled as well as amounts related to positions entered into and settled in the same month.

(c) These amounts do not represent unrealized gains or losses. Includes initial values of positions involving the receipt or payment of cash or other consideration, generally related to options purchased/sold.

Maturity Table — The following table presents the net commodity contract asset arising from recognition of fair values at June 30, 2012, scheduled by the source of fair value and contractual settlement dates of the underlying positions.

	Maturity dates of unrealized commodity contract net asset at June 30, 2012
Source of fair value	Less than 1 year			1-3 years			4-5 years			Excess of 5 years			Total
Prices actively quoted	$	9		$	(21	)	$	—		$	—		$	(12	)
Prices provided by other external sources	1,294			1,100			—			—			2,394

Percentage of total fair value	55		%	45		%	—		%	—		%	100		%

The "prices actively quoted" category reflects only exchange-traded contracts for which active quotes are readily available. The "prices provided by other external sources" category represents forward commodity positions valued using prices for which over-the-counter broker quotes are available in active markets. Over-the-counter quotes for power in ERCOT's North Hub that are deemed active markets extend through 2014 and over-the-counter quotes for natural gas generally extend through 2015, depending upon delivery point. The "prices based on models" category contains the value of all non-exchange-traded options, valued using option pricing models. In addition, this category contains other contractual arrangements that may have both forward and option components, as well as other contracts that are valued using proprietary long-term pricing models that utilize certain market based inputs. See Note 8 to Financial Statements for fair value disclosures and discussion of fair value measurements.

FINANCIAL CONDITION

Liquidity and Capital Resources

Cash Flow— Six Months Ended June 30, 2012 Compared to Six Months Ended June 30, 2011 — Cash provided by operating activities decreased $162 million to $225 million in 2012 driven by higher cash interest payments.

Depreciation and amortization expense reported in the statement of cash flows exceeded the amount reported in the statement of income by $98 million and $128 million in the six months ended June 30, 2012 and 2011, respectively. The difference represented amortization of nuclear fuel, which is reported as fuel costs in the statement of income consistent with industry practice, and amortization of intangible net assets arising from purchase accounting that is reported in various other income statement line items including operating revenues and fuel and purchased power costs and delivery fees.

Cash used in financing activities totaled $472 million in 2012 compared to $569 million in 2011. Activity in 2012 reflected repayment of borrowings under the TCEH Revolving Credit Facility. Activity in 2011 reflected the amendment and extension of the TCEH Senior Secured Facilities as discussed in Note 5 to Financial Statements.

See Note 5 to Financial Statements for further detail of short-term borrowings and long-term debt.

Cash provided by investing activities totaled $485 million in 2012 compared to $197 million in 2011. Activity in 2012 reflected settlement of $912 million of the TCEH demand notes receivable from EFH Corp. as compared to $549 million settled in 2011, partially offset by higher capital expenditures. Capital expenditures increased $116 million to $385 million in 2012 reflecting increased environmental related spending. Nuclear fuel purchases decreased $11 million due to timing. Restricted cash related to margin deposits provided $64 million of cash in 2012 compared to a $22 million of cash used in 2011

Debt Financing Activity— Activities related to short-term borrowings and long-term debt during the six months ended June 30, 2012 are as follows (all amounts presented are principal, and repayments and repurchases include amounts related to capital leases and exclude amounts related to debt discount, financing and reacquisition expenses):

	Borrowings		Repayments and Repurchases
TCEH (a)	$	103	$	(21	)
EFCH	—		(2		)
EFH Corp. (pushed down to EFCH) (b)	14		—
Total long-term	117		(23		)
Total short-term – TCEH (c)	—		(485		)
Total	$	117	$	(508	)

____________

(a) Borrowings represent $88 million of noncash principal increases of TCEH Toggle Notes issued in May 2012 in payment of accrued interest as discussed below under "Toggle Notes Interest Election" and sale/leaseback transactions for mining equipment entered into in 2012. Repayments represent $14 million of payments of principal at scheduled maturity dates and $7 million of payments of capital lease liabilities (see Note 5 to Financial Statements).

(b) Borrowings represent noncash principal increases of EFH Corp. Toggle Notes issued in May 2012 in payment of accrued interest as discussed below under "Toggle Notes Interest Election."

(c) Short-term amount represents net repayments of borrowings under the TCEH Revolving Credit Facility.

See Note 5 to Financial Statements for further detail of long-term debt and other financing arrangements, including $99 million of debt due currently (within 12 months) at June 30, 2012.

We regularly evaluate potential opportunities to improve our balance sheet through transactions that extend debt maturities or reduce the amount of our debt. Future activities under this liability management program may include, among others, the purchase of our outstanding debt for cash in open market purchases or privately negotiated refinancing, extension and exchange transactions (including pursuant to a Rule 10b-5(1) plan) or via public or private exchange or tender offers.

65

In evaluating whether to undertake any liability management transaction, including any refinancing or extension, we will take into account liquidity requirements, prospects for future access to capital, contractual restrictions, the market price of our outstanding debt and other factors. Any liability management transaction, including any refinancing or extension, may occur on a stand-alone basis or in connection with, or immediately following, other liability management transactions.

Available Liquidity — The following table summarizes changes in available liquidity in the six months ended June 30, 2012.

	Available Liquidity
	June 30, 2012		December 31, 2011		Change
Cash and cash equivalents	$	358	$	120	$	238
TCEH Revolving Credit Facility	1,869		1,384		485
TCEH Letter of Credit Facility	81		169		(88		)
Total liquidity	$	2,308	$	1,673	$	635

Available liquidity increased $635 million in the first half of 2012 reflecting EFH Corp.'s net repayment of $912 million of TCEH's demand notes receivable, the majority of which was used to repay borrowings under the TCEH Revolving Credit Facility (see Note 5 to Financial Statements). EFH Corp.'s repayment of the demand notes was funded by a debt issuance at EFIH in February 2012. The change in liquidity also reflected that capital expenditures, including nuclear fuel purchases, exceeded cash from operations by $256 million for the six months ended June 30, 2012. See discussion of cash flows above.

Secured Debt Capacity-At July 27, 2012, TCEH believes that it is permitted under its applicable debt agreements to issue additional senior secured debt (in each case, subject to certain exceptions and conditions set forth in its applicable debt documents) as follows:

• approximately $2.6 billion of additional aggregate principal amount of debt secured by substantially all of the assets of TCEH and certain of its subsidiaries (of which $750 million can be on a first-priority basis and the remainder on a second-priority basis) and

• an unlimited amount of additional first-priority debt in order to refinance the first-priority debt outstanding under the TCEH Senior Secured Facilities.

These amounts are estimates based on TCEH's current interpretation of the covenants set forth in its applicable debt agreements and do not take into account exceptions in the agreements that may allow for the incurrence of additional secured debt, including, but not limited to, acquisition debt, coverage ratio debt, refinancing debt, capital leases and hedging obligations. Moreover, such amounts could change from time to time as a result of, among other things, the termination of any debt agreement (or specific terms therein) or changes in the debt agreements that result from negotiations with new or existing lenders. In addition, covenants included in agreements governing additional future debt may impose greater restrictions on the incurrence of secured debt by TCEH. Consequently, the actual amount of senior secured debt that TCEH is permitted to incur under its debt agreements could be materially different than the amounts provided above.

Toggle Notes Interest Election — EFH Corp. and TCEH have the option every six months at their discretion, ending with the interest payment due November 2012, to use the payment-in-kind (PIK) feature of their respective toggle notes in lieu of making cash interest payments. EFH Corp. and TCEH elected to do so beginning with the May 2009 interest payment as an efficient and cost-effective method to further enhance liquidity. Once EFH Corp. and/or TCEH make a PIK election, the election is valid for each succeeding interest payment period until EFH Corp. and/or TCEH revoke the applicable election.

TCEH made its May 2012 payment and expects to make its November 2012 interest payment on the TCEH Toggle Notes by using the PIK feature of those notes. During the applicable interest periods, the interest rate on the notes is increased from 10.50% to 11.25%. TCEH increased the aggregate principal amount of the notes by $88 million in May 2012 and is expected to further increase the aggregate principal amount of the notes by $93 million in November 2012. The elections increased liquidity in May 2012 by an amount equal to $82 million and are expected to further increase liquidity in November 2012 by an amount equal to an estimated $87 million, constituting the amounts of cash interest that otherwise would have been payable on the notes.

66

Similarly, EFH Corp. made its May 2012 payment and expects to make its November 2012 interest payment on the EFH Corp. Toggle Notes by using the PIK feature of those notes. During the applicable interest periods, the interest rate on these notes is increased from 11.25% to 12.00%. EFH Corp. increased the aggregate principal amount of the notes by $26 million in May 2012 and is expected to issue an additional $28 million in November 2012. Also as a result of EFIH's ownership of EFH Corp. Toggle Notes ($2.951 billion principal amount at June 30, 2012), EFH Corp. issued to EFIH an additional $167 million aggregate principal amount of the notes in May 2012 and is expected to issue to EFIH an additional $177 million in November 2012. The elections increased liquidity in May 2012 by an amount equal to $25 million (excluding $156 million related to notes held by EFIH) and are expected to further increase liquidity in November 2012 by an amount equal to a currently estimated $26 million (excluding $166 million related to notes held by EFIH), constituting the amounts of cash interest that otherwise would have been payable on the notes. See Note 5 to Financial Statements for further discussion of the EFH Corp. Toggle Notes.

Liquidity Effects of Commodity Hedging and Trading Activities—Commodity hedging and trading transactions typically require a counterparty to post collateral if the forward price of the underlying commodity moves such that the hedging or trading instrument held by such counterparty has declined in value. TCEH uses cash, letters of credit, asset-backed liens and other forms of credit support to satisfy such collateral posting obligations. In addition, TCEH's Commodity Collateral Posting Facility (CCP facility), an uncapped senior secured revolving credit facility that matures in December 2012, funds the cash collateral posting requirements for a significant portion of the positions in the natural gas price hedging program not otherwise secured by a first-lien interest in the assets of TCEH. The aggregate principal amount of the CCP facility is determined by the exposure arising from higher forward market prices, regardless of the amount of such exposure, on a portfolio of certain natural gas hedging transaction volumes. Including those hedging transactions where margin deposits are covered by unlimited borrowings under the CCP facility, at June 30, 2012, approximately 90% of the long-term natural gas hedging program transactions were secured by a first-lien interest in the assets of TCEH that is pari passu with the TCEH Senior Secured Facilities, the effect of which is a significant reduction in the liquidity exposure associated with collateral posting requirements for those hedging transactions. Due to declines in forward natural gas prices, no amounts were outstanding under the CCP facility at June 30, 2012 or December 31, 2011. See Note 5 to Financial Statements for more information about the TCEH Senior Secured Facilities, which include the CCP facility.

Exchange cleared transactions typically require initial margin (i.e., the upfront cash and/or letter of credit posted to take into account the size and maturity of the positions and credit quality) in addition to variance margin (i.e., the daily cash margin posted to take into account changes in the value of the underlying commodity). The amount of initial margin required is generally defined by exchange rules. Clearing agents, however, typically have the right to request additional initial margin based on various factors including market depth, volatility and credit quality, which may be in the form of cash, letters of credit, a guaranty or other forms as negotiated with the clearing agent. Cash collateral received from counterparties is either used for working capital and other corporate purposes, including reducing short-term borrowings under credit facilities, or is required to be deposited in a separate account and restricted from being used for working capital and other corporate purposes. With respect to over-the-counter transactions, counterparties generally have the right to substitute letters of credit for such cash collateral. In such event, the cash collateral previously posted would be returned to such counterparties thereby reducing liquidity in the event that it was not restricted. At June 30, 2012, restricted cash collateral held totaled $65 million. See Note 12 to Financial Statements regarding restricted cash.

With the natural gas price hedging program, increases in natural gas prices generally result in increased cash collateral and letter of credit postings to counterparties. At June 30, 2012, approximately 100 million MMBtu of positions related to the natural gas price hedging program were not directly secured on an asset-lien basis and thus are subject to cash collateral posting requirements. The uncapped CCP facility supports the collateral posting requirements related to a significant portion of these positions. The positions supported by the CCP facility, under which there were no borrowings at June 30, 2012, mature by the end of 2012, when the CCP facility matures.

At June 30, 2012, TCEH received or posted cash and letters of credit for commodity hedging and trading activities as follows:

• $22 million in cash has been posted with counterparties for exchange cleared transactions (including initial margin), as compared to $50 million posted at December 31, 2011;

• $1.087 billion in cash has been received from counterparties, net of $1 million in cash posted, for over-the-counter and other non-exchange cleared transactions, as compared to $1.055 billion received, net of $6 million in cash posted, at December 31, 2011;

• $448 million in letters of credit have been posted with counterparties, as compared to $363 million posted at December 31, 2011, and

• $68 million in letters of credit have been received from counterparties, as compared to $103 million received at December 31, 2011.

67

Income Tax Refunds/Payments — Income tax payments related to the Texas margin tax are expected to total $37 million, and we do not expect to pay any federal income taxes to EFH Corp. in the next twelve months. Payments totaled $37 million in the six months ended June 30, 2012. (See Note 11 to Financial Statements.)

We cannot reasonably estimate the ultimate amounts and timing of tax payments associated with uncertain tax positions, but expect that no material federal income tax payments related to such positions will be made in the next 12 months. (See Note 12 to Financial Statements.)

Interest Rate Swap Transactions — See Note 5 to Financial Statements for discussion of TCEH's interest rate swaps.

Accounts Receivable Securitization Program— TCEH participates in EFH Corp.'s accounts receivable securitization program with financial institutions (the funding entities). In accordance with transfers and servicing accounting standards, the trade accounts receivable amounts under the program are reported as pledged balances and the related funding amounts are reported as short-term borrowings. Under the program, TXU Energy (originator) sells retail trade accounts receivable to TXU Receivables Company, a consolidated, wholly-owned, bankruptcy-remote, direct subsidiary of EFH Corp., which sells undivided interests in the purchased accounts receivable for cash to entities established for this purpose by the funding entities. All new trade receivables under the program generated by the originator are continuously purchased by TXU Receivables Company with the proceeds from collections of receivables previously purchased. Funding under the program totaled $142 million and $104 million at June 30, 2012 and December 31, 2011, respectively. See Note 4 to Financial Statements for a more complete description of the program, including the impact of the program on the financial statements for the periods presented and the contingencies that could result in termination of the program and a reduction of liquidity should the underlying financing be settled.

Financial Covenants, Credit Rating Provisions and Cross Default Provisions — The terms of certain of our financing arrangements contain maintenance covenants with respect to leverage ratios and/or minimum net worth. At June 30, 2012, we were in compliance with all such covenants.

Covenants and Restrictions under Financing Arrangements— The TCEH Senior Secured Facilities and the indentures governing substantially all of the debt we have issued in connection with, and subsequent to, the Merger contain covenants that could have a material impact on our liquidity and operations.

Adjusted EBITDA (as used in the maintenance covenant contained in the TCEH Senior Secured Facilities) for the twelve months ended June 30, 2012 totaled $3.617 billion for TCEH. See Exhibits 99(b) and 99(c) for a reconciliation of net loss to Adjusted EBITDA for TCEH and EFH Corp., respectively, in the six and twelve months ended June 30, 2012 and 2011.

68

The table below summarizes TCEH's secured debt to Adjusted EBITDA ratio under the maintenance covenant in the TCEH Senior Secured Facilities and various other financial ratios of EFH Corp. and TCEH that are applicable under certain other threshold covenants in the TCEH Senior Secured Facilities and the indentures governing the TCEH Senior Notes, the TCEH Senior Secured Notes, the TCEH Senior Secured Second Lien Notes, the EFH Corp. Senior Notes and the EFH Corp. Senior Secured Notes at June 30, 2012 and December 31, 2011. The debt incurrence and restricted payments/limitations on investments covenants thresholds described below represent levels that must be met in order for EFH Corp. or TCEH to incur certain permitted debt or make certain restricted payments and/or investments.

Material Credit Rating Covenants and Credit Worthiness Effects on Liquidity — As a result of TCEH's non-investment grade credit rating and considering collateral thresholds of certain retail and wholesale commodity contracts, at June 30, 2012, counterparties to those contracts could have required TCEH to post up to an aggregate of $49 million in additional collateral. This amount largely represents the below market terms of these contracts at June 30, 2012; thus, this amount will vary depending on the value of these contracts on any given day.

Certain transmission and distribution utilities in Texas have tariffs in place to assure adequate credit worthiness of any REP to support the REP's obligation to collect securitization bond-related (transition) charges on behalf of the utility. Under these tariffs, as a result of TCEH's below investment grade credit rating, TCEH is required to post collateral support in an amount equal to estimated transition charges over specified time periods. The amount of collateral support required to be posted, as well as the time period of transition charges covered, varies by utility. At June 30, 2012, TCEH has posted collateral support in the form of letters of credit to the applicable utilities in an aggregate amount equal to $27 million, with $12 million of this amount posted for the benefit of Oncor.

The PUCT has rules in place to assure adequate credit worthiness of each REP, including the ability to return customer deposits, if necessary. Under these rules, at June 30, 2012, TCEH posted letters of credit in the amount of $71 million, which are subject to adjustments.

The RRC has rules in place to assure that parties can meet their mining reclamation obligations, including through self-bonding when appropriate. If Luminant Generation Company LLC (a subsidiary of TCEH) does not continue to meet the self-bonding requirements as applied by the RRC, TCEH may be required to post cash, letter of credit or other tangible assets as collateral support in an amount currently estimated to be approximately $850 million to $1.0 billion. The actual amount (if required) could vary depending upon numerous factors, including the amount of Luminant Generation Company LLC's self-bond accepted by the RRC and the level of mining reclamation obligations.

ERCOT has rules in place to assure adequate credit worthiness of parties that participate in the "day-ahead" and "real-time markets" operated by ERCOT. Under these rules, TCEH has posted collateral support, predominantly in the form of letters of credit, totaling $130 million at June 30, 2012 (which is subject to daily adjustments based on settlement activity with ERCOT).

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 ratings below investment grade.

Other arrangements of EFCH and its subsidiaries, including the accounts receivable securitization program (see Note 4 to Financial Statements) and certain leases, contain terms pursuant to which the interest rates charged under the agreements may be adjusted depending on the relevant credit ratings.

In the event that any or all of the additional collateral requirements discussed above are triggered, we believe we would have adequate liquidity and/or financing capacity to satisfy such requirements.

Material Cross Default/Acceleration Provisions — Certain of our financing arrangements contain provisions that could result in an event of default if there were a failure under other financing arrangements to meet payment terms or to observe other covenants that could or does result in an acceleration of payments due. Such provisions are referred to as "cross default" or "cross acceleration" provisions.

A default by TCEH or any of its restricted subsidiaries in respect of indebtedness, excluding indebtedness relating to the accounts receivable securitization program, in an aggregate amount in excess of $200 million may result in a cross default under the TCEH Senior Secured Facilities. Under these facilities, such a default will allow the lenders to accelerate the maturity of outstanding balances ($20.426 billion at June 30, 2012) under such facilities.

The indentures governing the TCEH Senior Notes, TCEH Senior Secured Notes and the TCEH Senior Secured Second Lien Notes contain a cross acceleration provision where a payment default at maturity or on acceleration of principal indebtedness under any instrument or instruments of TCEH or any of its restricted subsidiaries in an aggregate amount equal to or greater than $250 million may cause the acceleration of the TCEH Senior Notes, TCEH Senior Secured Notes and TCEH Senior Secured Second Lien Notes.

Under the terms of a TCEH rail car lease, which had $42 million in remaining lease payments at June 30, 2012 and terminates in 2017, if TCEH failed to perform under agreements causing its indebtedness in aggregate principal amount of $100 million or more to become accelerated, the lessor could, among other remedies, terminate the lease and effectively accelerate the payment of any remaining lease payments due under the lease.

Under the terms of another TCEH rail car lease, which had $46 million in remaining lease payments at June 30, 2012 and terminates in 2028, if obligations of TCEH in excess of $200 million in the aggregate for payments of obligations to third party creditors under lease agreements, deferred purchase agreements or loan or credit agreements are accelerated prior to their original stated maturity, the lessor could, among other remedies, terminate the lease and effectively accelerate the payment of any remaining lease payments due under the lease.

The indentures governing the EFH Corp. Senior Secured Notes contain a cross acceleration provision whereby a payment default at maturity or on acceleration of principal indebtedness under any instrument or instruments of EFH Corp. or any of its restricted subsidiaries in an aggregate amount equal to or greater than $250 million may cause the acceleration of the EFH Corp. Senior Secured Notes.

The accounts receivable securitization program contains a cross default provision with a threshold of $200 million that applies in the aggregate to the originator, any parent guarantor of an originator or any subsidiary acting as collection agent under the program. TXU Receivables Company and EFH Corporate Services Company (a direct subsidiary of EFH Corp.), as collection agent, in the aggregate have a cross default threshold of $50,000. If any of these cross default provisions were triggered, the program could be terminated.

We enter into energy-related and financial contracts, the master forms of which contain provisions whereby an event of default or acceleration of settlement would occur if we were to default under an obligation in respect of borrowings in excess of thresholds, which vary, stated in the contracts. The subsidiaries whose default would trigger cross default vary depending on the contract.

Each ofTCEH's natural gas hedging agreements and interest rate swap agreements that are secured with a lien on its assets on a pari passu basis with the TCEH Senior Secured Facilities contains a cross default provision. In the event of a default by TCEH or any of its subsidiaries relating to indebtedness (such amounts varying by contract but ranging from $200 million to $250 million) that results in the acceleration of such debt, then each counterparty under these hedging agreements would have the right to terminate its hedge or interest rate swap agreement with TCEH and require all outstanding obligations under such agreement to be settled.

Other arrangements, including leases, have cross default provisions, the triggering of which would not be expected to result in a significant effect on liquidity.

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

All dollar amounts in the tables in the following discussion and analysis are stated in millions of US dollars unless otherwise indicated.

Market risk is the risk that we may experience a loss in value as a result of changes in market conditions affecting factors, such as commodity prices and interest rates, that may be experienced in the ordinary course of business. Our exposure to market risk is affected by a number of factors, including the size, duration and composition of our energy and financial portfolio, as well as the volatility and liquidity of markets. Instruments used to manage this exposure include interest rate swaps to manage interest rate risk related to debt, as well as exchange-traded, over-the-counter contracts and other contractual arrangements to manage commodity price risk.

Risk Oversight

We manage the commodity price, counterparty credit and commodity-related operational risk related to the unregulated energy business within limitations established by senior management and in accordance with overall risk management policies. Interest rate risk is managed centrally by the corporate treasury function. Market risks are monitored by risk management groups that operate independently of the wholesale commercial operations, utilizing defined practices and analytical methodologies. These techniques measure the risk of change in value of the portfolio of contracts and the hypothetical effect on this value from changes in market conditions and include, but are not limited to, Value at Risk (VaR) methodologies. Key risk control activities include, but are not limited to, transaction review and approval (including credit review), operational and market risk measurement, validation of transaction capture, portfolio valuation and reporting, including mark-to-market valuation, VaR and other risk measurement metrics.

EFH Corp. has a corporate risk management organization that is headed by the Chief Financial Officer, who also functions as the Chief Risk Officer. The Chief Risk Officer, through his designees, enforces applicable risk limits, including the respective policies and procedures to ensure compliance with such limits and evaluates the risks inherent in our businesses.

Commodity Price Risk

We are subject to the inherent risks of market fluctuations in the price of electricity, natural gas and other energy-related products we market or purchase. We actively manage the portfolio of owned generation assets, fuel supply and retail sales load to mitigate the near-term impacts of these risks on results of operations. Similar to other participants in the market, we cannot fully manage the long-term value impact of structural declines or increases in natural gas and power prices and spark spreads (differences between the market price of electricity and its cost of production).

In managing energy price risk, we enter into a variety of market transactions including, but not limited to, short- and long-term contracts for physical delivery, exchange-traded and over-the-counter financial contracts and bilateral contracts with customers. Activities include hedging, the structuring of long-term contractual arrangements and proprietary trading. We continuously monitor the valuation of identified risks and adjust positions based on current market conditions. We strive to use consistent assumptions regarding forward market price curves in evaluating and recording the effects of commodity price risk.

Natural Gas Price Hedging Program —See "Significant Activities and Events" above for a description of the program, including potential effects on reported results.

VaR Methodology — A VaR methodology is used to measure the amount of market risk that exists within the portfolio under a variety of market conditions. The resultant VaR produces an estimate of a portfolio's potential for loss given a specified confidence level and considers, among other things, market movements utilizing standard statistical techniques given historical and projected market prices and volatilities.

A Monte Carlo simulation methodology is used to calculate VaR and is considered by management to be the most effective way to estimate changes in a portfolio's value based on assumed market conditions for liquid markets. The use of this method requires a number of key assumptions, such as use of (i) an assumed confidence level; (ii) an assumed holding period (i.e., the time necessary for management action, such as to liquidate positions); and (iii) historical estimates of volatility and correlation data.

72

Trading VaR — This measurement estimates the potential loss in fair value, due to changes in market conditions, of all contracts entered into for trading purposes based on a 95% confidence level and an assumed holding period of five to 60 days.

	Six Months Ended June 30, 2012		Year Ended December 31, 2011
Month-end average Trading VaR:	$	11	$	4
Month-end high Trading VaR:	$	12	$	8
Month-end low Trading VaR:	$	10	$	1

VaR for Energy-Related Contracts Subject to Mark-to-Market (MtM) Accounting — This measurement estimates the potential loss in fair value, due to changes in market conditions, of all contracts marked-to-market in net income (principally hedges not accounted for as cash flow hedges and trading positions), based on a 95% confidence level and an assumed holding period of five to 60 days.

	Six Months Ended June 30, 2012		Year Ended December 31, 2011
Month-end average MtM VaR:	$	153	$	195
Month-end high MtM VaR:	$	206	$	268
Month-end low MtM VaR:	$	120	$	121

Earnings at Risk (EaR) — This measurement estimates the potential reduction of pretax earnings for the periods presented, due to changes in market conditions, of all energy-related contracts marked-to-market in net income and contracts not marked-to-market in net income that are expected to be settled within the fiscal year (physical purchases and sales of commodities). Transactions accounted for as cash flow hedges are also included for this measurement. A 95% confidence level and a five to 60 day holding period are assumed in determining EaR.

	Six Months Ended June 30, 2012		Year Ended December 31, 2011
Month-end average EaR:	$	113	$	170
Month-end high EaR:	$	161	$	228
Month-end low EaR:	$	77	$	121

The increase in the Trading VaR risk measure above reflected higher market volatility and an increase in trading positions. The decreases in the MtM VaR and EaR risk measures above reflected a reduction of positions in the natural gas price hedging program due to maturities and lower forward natural gas prices.

Interest Rate Risk

At June 30, 2012, the potential reduction of annual pretax earnings over the next twelve months due to a one percentage-point (100 basis points) increase in floating interest rates on long-term debt totaled $10 million, taking into account the interest rate swaps discussed in Note 5 to Financial Statements.

Credit Risk

Credit risk relates to the risk of loss associated with nonperformance by counterparties. We maintain credit risk policies with regard to our counterparties to minimize overall credit risk. These policies prescribe practices for evaluating a potential counterparty's financial condition, credit rating and other quantitative and qualitative credit criteria and authorize specific risk mitigation tools including, but not limited to, use of standardized master netting contracts and agreements that allow for netting of positive and negative exposures associated with a single counterparty. We have processes for monitoring and managing credit exposure of our businesses including methodologies to analyze counterparties' financial strength, measurement of current and potential future exposures and contract language that provides rights for netting and set-off. Credit enhancements such as parental guarantees, letters of credit, surety bonds and margin deposits are also utilized. Additionally, individual counterparties and credit portfolios are managed to assess overall credit exposure. This evaluation results in establishing exposure limits or collateral requirements for entering into an agreement with a counterparty that creates exposure. Additionally, we have established controls to determine and monitor the appropriateness of these limits on an ongoing basis. Prospective material changes in the payment history or financial condition of a counterparty or downgrade of its credit quality result in the reassessment of the credit limit with that counterparty. This process can result in the subsequent reduction of the credit limit or a request for additional financial assurances.

73

Credit Exposure — Our gross exposure to credit risk associated with trade accounts receivable (retail and wholesale) and net asset positions (before credit collateral) arising from commodity contracts and hedging and trading activities totaled $1.835 billion at June 30, 2012. The components of this exposure are discussed in more detail below.

Assets subject to credit risk at June 30, 2012 include $544 million in retail trade accounts receivable before taking into account cash deposits held as collateral for these receivables totaling $67 million. The risk of material loss (after consideration of bad debt allowances) from nonperformance by these customers is unlikely based upon historical experience. Allowances for uncollectible accounts receivable are established for the potential loss from nonpayment by these customers based on historical experience, market or operational conditions and changes in the financial condition of large business customers.

The remaining credit exposure arises from wholesale trade receivables, commodity contracts and hedging and trading activities, including interest rate hedging. Counterparties to these transactions include energy companies, financial institutions, electric utilities, independent power producers, oil and gas producers, local distribution companies and energy trading and marketing companies. At June 30, 2012, the exposure to credit risk from these counterparties totaled $1.291 billion taking into account the standardized master netting contracts and agreements described above but before taking into account $1.103 billion in credit collateral (cash, letters of credit and other credit support). The net exposure (after credit collateral) of $188 million decreased $393 million in the six months ended June 30, 2012, driven by maturities of positions in the natural gas price hedging program, increased collateral received due to recent credit rating downgrades of financial institution counterparties and contractual credit enhancements.

Of this $188 million net exposure, essentially all is with investment grade customers and counterparties, as determined using publicly available information including major rating agencies' published ratings and our internal credit evaluation process. Those customers and counterparties without a S&P rating of at least BBB- or similar rating from another major rating agency are rated using internal credit methodologies and credit scoring models to estimate a S&P equivalent rating. The company routinely monitors and manages credit exposure to these customers and counterparties on this basis.

The following table presents the distribution of credit exposure at June 30, 2012 arising from wholesale trade receivables, commodity contracts and hedging and trading activities. This credit exposure represents wholesale trade accounts receivable and net asset positions in the balance sheet arising from hedging and trading activities after taking into consideration netting provisions within each contract, setoff provisions in the event of default and any master netting contracts with counterparties. Credit collateral includes cash and letters of credit, but excludes other credit enhancements such as liens on assets. See Note 9 to Financial Statements for further discussion of portions of this exposure related to activities marked-to-market in the financial statements.

									Gross Exposure by Maturity
	Exposure Before Credit Collateral			Credit Collateral		Net Exposure			2 years or less		Between 2-5  years		Greater than 5 years		Total
Investment grade	$	1,279		$	1,093	$	186		$	1,106	$	173	$	—	$	1,279
Noninvestment grade	12			10		2			12		—		—		12
Totals	$	1,291		$	1,103	$	188		$	1,118	$	173	$	—	$	1,291
Investment grade	99.1		%			98.9		%
Noninvestment grade	0.9		%			1.1		%

In addition to the exposures in the table above, contracts classified as "normal" purchase or sale and non-derivative contractual commitments are not marked-to-market in the financial statements. Such contractual commitments may contain pricing that is favorable considering current market conditions and therefore represent economic risk if the counterparties do not perform. Nonperformance could have a material impact on future results of operations, liquidity and financial condition.

Significant (10% or greater) concentration of credit exposure exists with five counterparties, which represented 30%, 18%, 15%, 11% and 11% of the $188 million net exposure. We view exposure to these counterparties to be within an acceptable level of risk tolerance due to the counterparties' credit ratings, each of which is rated as investment grade, and the importance of our business relationship with the counterparties.

74

With respect to credit risk related to the natural gas price hedging program, all of the transaction volumes are with counterparties that have an investment grade credit rating. However, there is current and potential credit concentration risk related to the limited number of counterparties that comprise the substantial majority of the program with such counterparties being in the banking and financial sector. The transactions with these counterparties contain certain credit rating provisions that would require the counterparties to post collateral in the event of a material downgrade in the credit rating of the counterparties. An event of default by one or more hedge counterparties could subsequently result in termination-related settlement payments that reduce available liquidity if amounts are owed to the counterparties related to the commodity contracts or delays in receipts of expected settlements if the hedge counterparties owe amounts to us. While the potential concentration of risk with these counterparties is viewed to be within an acceptable risk tolerance, the exposure to hedge counterparties is managed through the various ongoing risk management measures described above.

75

INDUSTRY AND MARKET INFORMATION

The industry and market data and other statistical information used throughout this report are based on independent industry publications, government publications, reports by market research firms or other published independent sources, including certain data published by ERCOT, the PUCT and NYMEX. We did not commission any of these publications or reports. Some data is also based on good faith estimates, which are derived from our review of internal surveys, as well as the independent sources listed above. Independent industry publications and surveys generally state that they have obtained information from sources believed to be reliable, but do not guarantee the accuracy and completeness of such information. While we believe that each of these studies and publications is reliable, we have not independently verified such data and make no representation as to the accuracy of such information. Forecasts are particularly likely to be inaccurate, especially over long periods of time, and we do not know what assumptions regarding general economic growth are used in preparing the forecasts included in this report. Similarly, while we believe that such internal and external research is reliable, it has not been verified by any independent sources, and we make no assurances that the predictions contained therein are accurate.

Item 4.   CONTROLS AND PROCEDURES

An evaluation was performed under the supervision and with the participation of our management, including the principal executive officer and principal financial officer, of the effectiveness of the design and operation of the disclosure controls and procedures in effect at the end of the current period included in this quarterly report. Based on the evaluation performed, our management, including the principal executive officer and principal financial officer, concluded that the disclosure controls and procedures were effective. During the most recent fiscal quarter covered by this quarterly report, there has been no change in our internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Exhibit 95(a)

Mine Safety Disclosures

Safety is a top priority in all our businesses, and accordingly, it is a key component of our focus on operational excellence, our employee performance reviews and employee compensation. Our health and safety program objectives are to prevent workplace accidents and ensure that all employees return home safely and comply with all regulations.

We currently own and operate 12 surface lignite coal mines in Texas to provide fuel for our electricity generation facilities. These mining operations are regulated by the US Mine Safety and Health Administration (MSHA) under the Federal Mine Safety and Health Act of 1977, as amended (the Mine Act), as well as other regulatory agencies such as the RRC. The MSHA inspects US mines, including ours, on a regular basis and if it believes a violation of the Mine Act or any health or safety standard or other regulation has occurred, it may issue a citation or order, generally accompanied by a proposed fine or assessment. Such citations and orders can be contested and appealed to the Federal Mine Safety and Health Review Commission (FMSHRC), which often results in a reduction of the severity and amount of fines and assessments and sometimes results in dismissal. The number of citations, orders and proposed assessments vary depending on the size of the mine as well as other factors.

Disclosures related to specific mines pursuant to Section 1503 of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 104 of Regulation S-K sourced from data documented as of July 9, 2012 in the MSHA Data Retrieval System for the three months ended June 30, 2012 (except pending legal actions, which are at June 30, 2012), are as follows:
