General [Abstract]
GENERAL	NOTE 1 GENERAL The Company is a diversified energy company. It is the parent company of Detroit Edison and MichCon, regulated electric and gas utilities engaged primarily in the business of providing electricity and natural gas sales, distribution and storage services throughout southeastern Michigan. The Company also operates four energy-related non-utility segments with operations throughout the United States. These Consolidated Financial Statements should be read in conjunction with the Notes to Consolidated Financial Statements included in the 2008 Annual Report on Form 10-K, as updated to reflect certain accounting changes on Form 8-K dated August20, 2009. The accompanying Consolidated Financial Statements are prepared using accounting principles generally accepted in the United States of America. These accounting principles require management to use estimates and assumptions that impact reported amounts of assets, liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities. Actual results may differ from the Companys estimates. The Consolidated Financial Statements are unaudited, but in our opinion include all adjustments necessary for a fair presentation of such financial statements. All adjustments are of a normal recurring nature, except as otherwise disclosed in these Consolidated Financial Statements and Notes to Consolidated Financial Statements. Financial results for this interim period are not necessarily indicative of results that may be expected for any other interim period or for the fiscal year ending December31, 2009. Certain prior year amounts have been reclassified to reflect current year classifications. Asset Retirement Obligations The Company has a legal retirement obligation for the decommissioning costs for its Fermi 1 and Fermi 2 nuclear plants. To a lesser extent, the Company has legal retirement obligations for gas production facilities, gas gathering facilities and various other operations. The Company has conditional retirement obligations for gas pipeline retirement costs and disposal of asbestos at certain of its power plants. To a lesser extent, the Company has conditional retirement obligations at certain service centers, compressor and gate stations, and disposal costs for PCB contained within transformers and circuit breakers. The Company recognizes such obligations as liabilities at fair market value when they are incurred, which generally is at the time the associated assets are placed in service. Fair value is measured using expected future cash outflows discounted at our credit-adjusted risk-free rate. In its regulated operations, the Company defers timing differences that arise in the expense recognition of legal asset retirement costs that are currently recovered in rates. A reconciliation of the asset retirement obligations for the nine months ended September30, 2009 follows: (in Millions) Asset retirement obligations at January1, 2009 $ 1,361 Accretion 66 Liabilities settled (10 ) Revision in estimated cash flows 5 Asset retirement obligations at September30, 2009 1,422

New Accounting Pronouncements [Abstract]
NEW ACCOUNTING PRONOUNCEMENTS	NOTE 2 NEW ACCOUNTING PRONOUNCEMENTS FASB Accounting Standards Codification (Codification) In June2009, the FASB voted to approve that on July1, 2009, the Codification will become the single source of authoritative nongovernmental U.S. GAAP. The Codification is a reorganization of current GAAP into a topical format that eliminates the current GAAP hierarchy and establishes two levels of guidance authoritative and non-authoritative. According to the FASB, all non-grandfathered, non-SEC accounting literature that is not included in the Codification would be considered non-authoritative. The FASB has indicated that the Codification does not change current GAAP. Instead, the proposed changes aim to (1)reduce the time and effort it takes for users to research accounting questions and (2)improve the usability of current accounting standards. The Codification is effective for interim and annual periods ending after September15, 2009. Fair Value Accounting In September2006, the FASB issued ASC 820 (SFAS No.157, Fair Value Measurements). The standard defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. It emphasizes that fair value is a market-based measurement, not an entity-specific measurement. Fair value measurement should be determined based on the assumptions that market participants would use in pricing an asset or liability. Effective January1, 2008, the Company adopted ASC 820 (SFAS No. 157). As permitted by ASC 820-10 (FSP No.157-2), the Company elected to defer the effective date of the standard as it pertains to measurement and disclosures about the fair value of non-financial assets and liabilities made on a nonrecurring basis. The Company has adopted the recognition provisions for non-financial assets and liabilities as of January1, 2009. See Note 3. In April2009, the FASB issued three FSPs intended to provide additional application guidance and enhance disclosures regarding fair value measurements and impairments of securities. The FSPs are effective for interim and annual periods ending after June15, 2009. ASC 825-10 (FSP No.107-1 and APB No.28-1), Interim Disclosures about Fair Value of Financial Instruments, expands the fair value disclosures required for all financial instruments within the scope of SFAS No.107 to interim periods. ASC 820-10 (FSP No.157-4), Determining Fair Value When the Volume and Level of Activity for the Asset or Liability Have Significantly Decreased and Identifying Transactions That Are Not Orderly, which applies to all assets and liabilities, i.e., financial and nonfinancial, reemphasizes that the objective of fair value remains unchanged (i.e., an exit price notion). The FSP provides application guidance on measuring fair value when the volume and level of activity has significantly decreased and identifying transactions that are not orderly. The FSP also emphasizes that an entity cannot presume that an observable transaction price is not orderly even when there has been a significant decline in the volume and level of activity. ASC 320-10 (FSP

Financial And Other Derivative Instruments And Fair Value [Abstract]
FINANCIAL AND OTHER DERIVATIVE INSTRUMENTS AND FAIR VALUE	NOTE 3 FINANCIAL AND OTHER DERIVATIVE INSTRUMENTS AND FAIR VALUE Financial and Other Derivative Instruments The Company recognizes all derivatives on the Consolidated Statement of Financial Position at their fair value unless they qualify for certain scope exceptions, including normal purchases and normal sales exception. Further, derivatives that qualify and are designated for hedge accounting are classified as either hedges of a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability (cash flow hedge), or as hedges of the fair value of a recognized asset or liability or of an unrecognized firm commitment (fair value hedge). For cash flow hedges, the portion of the derivative gain or loss that is effective in offsetting the change in the value of the underlying exposure is deferred in Accumulated other comprehensive income and later reclassified into earnings when the underlying transaction occurs. For fair value hedges, changes in fair values for both the derivative and the underlying hedged exposure are recognized in earnings each period. Gains and losses from the ineffective portion of any hedge are recognized in earnings immediately. For derivatives that do not qualify or are not designated for hedge accounting, changes in the fair value are recognized in earnings each period. The Companys primary market risk exposure is associated with commodity prices, credit, interest rates and foreign currency. The Company has risk management policies to monitor and manage market risks. The Company uses derivative instruments to manage some of the exposure. The Company uses derivative instruments for trading purposes in its Energy Trading segment and the coal marketing activities of its Power and Industrial Projects segment. Contracts the Company typically classifies as derivative instruments include power, gas, oil and certain coal forwards, futures, options and swaps, and foreign currency contracts. Items not generally classified as derivatives include proprietary gas inventory, gas storage and transportation arrangements, and gas and oil reserves. The fair value of all derivatives is included in Derivative assets or liabilities on the Consolidated Statements of Financial Position. Utility Operations Detroit Edison Detroit Edison generates, purchases, distributes and sells electricity. Detroit Edison uses forward energy and capacity contracts to manage changes in the price of electricity and fuel. Substantially all of these contracts meet the normal purchases and sales exemption and are therefore accounted for under the accrual method. Other derivative contracts are recoverable through the PSCR mechanism when realized. This results in the deferral of unrealized gains and losses as Regulatory assets or liabilities, until realized. MichCon MichCon purchases, stores, transports and distributes natural gas and sells storage and transportation capacity. MichCon has fixed-priced contracts for portions of its expected gas supply requirements through 2013. These gas-supply contracts are designated and qualify for the normal purchases and sales exemption and are

Disposals And Discontinued Operations [Abstract]
DISPOSALS AND DISCONTINUED OPERATIONS	NOTE 4 DISPOSALS AND DISCONTINUED OPERATIONS Sale of Interest in Barnett Shale Properties In 2008, the Company sold a portion of its Barnett shale properties for gross proceeds of approximately $260million. The Company recognized a gain of $128million ($80million after-tax) on the sale in the nine months ended September30, 2008. Synthetic Fuel Business Due to the expiration of synfuel production tax credits in 2007, the Synthetic Fuel business ceased operations and was classified as a discontinued operation as of December31, 2007. The favorable impact of reserve adjustments for the final phase-out percentage of approximately $32million, the final settlement of other miscellaneous assets and liabilities and related tax impacts resulted in net income of $20million for the first nine months of 2008. The Company has provided certain guarantees and indemnities in conjunction with the sales of interests in its synfuel facilities. The guarantees cover potential tax-related obligations and will survive until 90days after expiration of all applicable statutes of limitations. The Company estimates that its maximum potential liability under these guarantees at September30, 2009 is $2.9 billion.

Regulatory Matters [Abstract]
REGULATORY MATTERS	NOTE 5 REGULATORY MATTERS 2009 Electric Rate Case Filing Detroit Edison filed a general rate case on January26, 2009 based on a twelve months ended June 2008 historical test year. The filing with the MPSC requested a $378million, or 8.1percent average increase in Detroit Edisons annual revenues for the twelve months ended June30, 2010 projected test year. The requested $378million increase in revenues is required to recover the increased costs associated with environmental compliance, operation and maintenance of the Companys electric distribution system and generation plants, customer uncollectible accounts, inflation, the capital costs of plant additions and the reduction in territory sales. In addition, Detroit Edisons filing made, among other requests, the following proposals: Continued progress toward correcting the existing rate structure to more accurately reflect the actual cost of providing service to business customers; Continued application of an adjustment mechanism to enable the Company to address the costs associated with retail electric customers migrating to and from Detroit Edisons full service retail electric tariff service; Application of an uncollectible expense true-up mechanism based on the $87million expense level of uncollectible expenses that occurred during the 12month period ended June2008; Continued application of the storm restoration expense recovery mechanism and modification to the line clearance expense recovery mechanism; and Implementation of a revenue decoupling mechanism. Revenue decoupling is an adjustment mechanism that would provide revenues consistent with the allowed revenue requirement with a periodic adjustment for changes in sales levels. Pursuant to an MPSC order issued May26, 2009, Detroit Edison filed proposed tariffs on June26, 2009 to implement $280million of its requested annual increase on July26, 2009. On July16, 2009, the MPSC issued an order requiring Detroit Edison to implement the increase by applying the rate design reflected in its January26, 2009 application. This increase will remain in place until a final order is issued by the MPSC, which is expected in January2010. Detroit Edison recorded approximately $40million of increased revenues in the third quarter of 2009 as a result of the self-implemented rates. If the final rate case order does not support the self-implemented rate increase, Detroit Edison must refund the difference with interest. We have assessed whether a refund will be likely in accordance with the requirements of ASC 450-20 Loss Contingencies and believe that it is reasonably possible, but not probable, that Detroit Edison will be required to refund some or all of its self-implemented rate increase and therefore have not recorded a refund liability as of September 30, 2009. Renewable Energy Plan In March2009, Detroit Edison filed its Renewable Energy Plan with the MPSC as required under 2008 PA 295. The Renewable Energy Plan application requests authority to recover approximately $35 million of additional revenue in 2009. The proposed revenue increase is necessary in order to properly implement

Common Stock and Earnings Per Share [Abstract]
COMMON STOCK AND EARNINGS PER SHARE	NOTE 6 COMMON STOCK AND EARNINGS PER SHARE The Company reports both basic and diluted earnings per share. The calculation of diluted earnings per share assumes the issuance of potentially dilutive common shares outstanding during the period from the exercise of stock options. Effective January1, 2009, the adoption of new accounting requirements clarifying the definition of participating securities to be included in the earnings per share calculation had the effect of reducing previously reported 2008 amounts for basic and diluted earnings per share by $.02 and $.01, respectively.

SHORT-TERM CREDIT ARRANGEMENTS AND BORROWINGS	NOTE 8 SHORT-TERM CREDIT ARRANGEMENTS AND BORROWINGS DTE Energy and its wholly-owned subsidiaries, Detroit Edison and MichCon, have entered into revolving credit facilities with similar terms. The five-year and two-year revolving credit facilities are with a syndicate of 22 banks and may be used for general corporate borrowings, but are intended to provide liquidity support for each of the companies commercial paper programs. No one bank provides more than 8.5% of the combined credit facilities. Borrowings under the facilities are available at prevailing short-term interest rates. Additionally, DTE Energy, Detroit Edison and MichCon have various other bank loans and facilities. The above agreements require the Company to maintain a debt to total capitalization ratio of no more than 0.65 to 1. DTE Energy, Detroit Edison and MichCon are in compliance with this financial covenant. The availability under these combined facilities at September30, 2009 is shown in the following table: (in Millions) DTE Energy Detroit Edison MichCon Total Five-year unsecured revolving facility, expiring October2010 $ 675 $ 69 $ 181 $ 925 Two-year unsecured revolving facility, expiring April2011 538 212 250 1,000 One-year unsecured letter of credit facility, expiring in November2009 30 30 One-year unsecured letter of credit facility, expiring in June 2010 70 70 Two-year unsecured letter of credit facility, expiring in May2011 50 50 Total credit facilities at September30, 2009 1,363 281 431 2,075 Amounts outstanding at September30, 2009: Commercial paper issuances 205 205 Borrowings Letters of credit 228 228 228 205 433 Net availability at September30, 2009 $ 1,135 $ 281 $ 226 $ 1,642 The Company has other outstanding letters of credit which are not included in the above described facilities totaling approximately $16million which are used for various corporate purposes.

Commitments And Contingencies [Abstract]
COMMITMENTS AND CONTINGENCIES	NOTE 9 COMMITMENTS AND CONTINGENCIES Environmental Electric Utility Air Detroit Edison is subject to EPA ozone transport and acid rain regulations that limit power plant emissions of sulfur dioxide and nitrogen oxides. Since 2005, EPA and the State of Michigan issued additional emission reduction regulations and continue to develop additional rules and emission standards relating to ozone, fine particulate, regional haze and mercury air pollution. The new rules will lead to additional controls on fossil-fueled power plants to reduce nitrogen oxide, sulfur dioxide and mercury emissions. To comply with these requirements, Detroit Edison has spent approximately $1.4billion through 2008. The Company estimates Detroit Edisons future undiscounted capital expenditures at up to approximately $100million in 2009 and up to approximately $2.3billion of additional capital expenditures through 2019 based on current regulations. In July2009, DTE Energy received a Notice of Violation/Finding of Violation (NOV/FOV) from the EPA alleging, among other things, that five Detroit Edison power plants violated New Source Performance standards, Prevention of Significant Deterioration requirements, and Title V operating permit requirements under the Clean Air Act. We believe that the plants identified by the EPA have complied with applicable regulations. Depending upon the outcome of our discussions with the EPA regarding the NOV/FOV, the EPA could bring legal action against Detroit Edison. We could also be required to install additional pollution control equipment at some or all of the power plants in question, engage in Supplemental Environmental Programs, and/or pay fines. We cannot predict the financial impact or outcome of this matter, or the timing of its resolution. Water In response to an EPA regulation, Detroit Edison is required to examine alternatives for reducing the environmental impacts of the cooling water intake structures at several of its facilities. Based on the results of the studies to be conducted over the next several years, Detroit Edison may be required to install additional control technologies to reduce the impacts of the water intakes. Initially, it was estimated that Detroit Edison could incur up to approximately $55million over the four to six years subsequent to 2008 in additional capital expenditures to comply with these requirements. However, a January2007 circuit court decision remanded back to the EPA several provisions of the federal regulation that may result in a delay in compliance dates. The decision also raised the possibility that Detroit Edison may have to install cooling towers at some facilities at a cost substantially greater than was initially estimated for other mitigative technologies. In 2008, the Supreme Court agreed to review the remanded cost-benefit analysis provision of the rule. In April2009, the Supreme Court ruled that a cost-benefit analysis is a permissible provision of the rule. Concurrently, the EPA continues to develop a revised rule, which is expected to be published later in 2009.
