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. 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 records asset retirement obligations in accordance with SFAS No.143, Accounting for Asset Retirement Obligations and FASB Interpretation Number (FIN)47, Accounting for Conditional Asset Retirement Obligations, an interpretation of FASB Statement No.143. 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. For the Companys regulated operations, timing differences arise in the expense recognition of legal asset retirement costs that the Company is currently recovering in rates. The Company defers such differences under SFAS No.71, Accounting for the Effects of Certain Types of Regulation. A reconciliation of the asset retirement obligations for the six months

New Accounting Pronouncements [Abstract]
NEW ACCOUNTING PRONOUNCEMENTS	NOTE 2 NEW ACCOUNTING PRONOUNCEMENTS Fair Value Accounting In September2006, the FASB issued SFAS No.157, Fair Value Measurements. SFAS No.157 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 SFAS No.157. As permitted by FASB Staff Position FAS No.157-2, the Company elected to defer the effective date of SFAS No.157 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 for further disclosures. 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. FSP FAS 107-1 and APB 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. FSP FAS 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. FSP FAS 115-2 and FAS 124-2, Recognition and Presentation of Other-Than-Temporary Impairments, is intended to bring greater consistency to the timing of impairment recognition, and provide greater clarity to investors about the credit and noncredit components of impaired debt securities that are not expected to be sold. The Company adopted these FSPs in the second quarter of 2009. The adoption of these FSPs did not have a significant impact on DTE Energys consolidated financial statements. Determining Whether Instruments Granted in Share-Based Payment Transactions Are Participating Securities In June2008, the FASB issued FSP EITF 03-6-1, Determining Whether Instruments Granted in Share-Based Payment Transactions are Participating Securities. This FSP addresses whether instruments granted in share-based payment transactions are participating securities prior to vesting and, therefore, need to be included in the earnings all

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 complies with SFAS No.133, Accounting for Derivative Instruments and Hedging Activities, as amended and interpreted. Under SFAS No.133, all derivatives are recognized 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, certain coal and oil forwards, futures, options and swaps, and foreign currency contracts. Items it does not generally account for 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 expect

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 six months ended June30, 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 $16million, the final settlement of other miscellaneous assets and liabilities and related tax impacts resulted in net income of $12million for the first six 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 commercial, environmental, oil price and 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 June30, 2009 is $2.9billion.

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 June 2008; 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. 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. Detroit Edison expects the impact of this self-implemented increase would be significantly offset by its plan to begin reducing its PSCR factor beginning August1, 2009. This increase will remain in place until a final order is issued by the MPSC, which is expected in January2010. If the final rate case order provides for lower rates than we have self-implemented, we must refund the difference with interest. Cost-Based Tariffs for Schools In January2009, Detroit Edison filed a required application that included two new cost-based tariffs for schools, universities and community colleges. The filing is in compliance with Public Act 286 which required utilities to file tariffs that ensure that eligible educational institutions are charged retail electric rates that reflect the actual cost of providing service to those customers. In February2009, an MPSC order consolidated this proceeding with the January26, 2009 electric rate case filing. 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 necessar

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 Company adopted FSP EITF 03-6-1, Determining Whether Instruments Granted in Share-Based Payment Transactions are Participating Securities.

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 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 $100 million 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 Review standards, Prevention of Significant Deterioration requirements, and Title V operating permit requirements under the Clean Air Act. We are in the process of preparing our response to the NOV/FOV, but 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. Global Climate Change Proposals for voluntary initiatives and mandatory controls are being discussed in the United States to reduce greenhouse gases such as carbon dioxide, a by-product of burning fossil fuels. On June26, 2009, the U.S. House of Representatives passed the American Clean Energy and Security Act (ACESA). The bill has yet to be taken up by the U.S. Senate. The ACESA includes a cap and trade program that would start in 2012 and provides for costs for emissions of greenhouse gases (e.g. carbon dioxide). Meanwhile, the EPA is beginning to implement regulatory action under the Clean Air Act to address climate change. There may be further legislative and or regulatory action to address the issue of changes in climate that may result from the build-up of greenhouse gases in the atmosphere. If passed, legislative or regulatory actions as currently being discussed could have a material impact on our operations and financial position and the rates we charge our customers. 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 intak
