Safe Harbor Statement The information contained herein is as of the date of this presentation. DTE Energy expressly disclaims any current intention to update any forward-looking statements contained in this document as a result of new information or future events or developments. Words such as "anticipate," "believe," "expect," "projected" and "goals" signify forward-looking statements. Forward-looking statements are not guarantees of future results and conditions but rather are subject to various assumptions, risks and uncertainties. This presentation contains forward-looking statements about DTE Energy's financial results and estimates of future prospects, and actual results may differ materially. Factors that may impact forward-looking statements include, but are not limited to: the higher price of oil and its impact on the value of production tax credits, and the ability to utilize and/or sell interests in facilities producing such credits, or the potential requirement to refund proceeds received from synfuel partners; the uncertainties of successful exploration of gas shale resources and inability to estimate gas reserves with certainty; the effects of weather and other natural phenomena on operations and sales to customers, and purchases from suppliers; economic climate and population growth or decline in the geographic areas where we do business; environmental issues, laws and regulations, and the cost of remediation and compliance; nuclear regulations and operations associated with nuclear facilities; implementation of electric and gas Customer Choice programs; impact of electric and gas utility restructuring in Michigan, including legislative amendments; employee relations and the impact of collective bargaining agreements; unplanned outages; access to capital markets and capital market conditions and the results of other financing efforts which can be affected by credit agency ratings; the timing and extent of changes in interest rates; the level of borrowings; changes in the cost and availability of coal and other raw materials, purchased power and natural gas; effects of competition; impact of regulation by the FERC, MPSC, NRC and other applicable governmental proceedings and regulations; contributions to earnings by non-utility subsidiaries; changes in and application of federal, state and local tax laws and their interpretations, including the Internal Revenue Code, regulations, rulings, court proceedings and audits; the ability to recover costs through rate increases; the availability, cost, coverage and terms of insurance; the cost of protecting assets against, or damage due to terrorism; changes in and application of accounting standards and financial reporting regulations; changes in federal or state laws and their interpretation with respect to regulation, energy policy and other business issues; uncollectible accounts receivable; litigation and related appeals and changes in the economic and financial viability of our suppliers, customers and trading counterparties, and the continued ability of such parties to perform their obligations to the Company. This presentation should also be read in conjunction with the "Forward-Looking Statements" section in each of DTE Energy's, MichCon's and Detroit Edison's 2005 Form 10-K, and the 2006 quarterly reports on Form 10-Q (which sections are incorporated herein by reference), and in conjunction with other SEC reports filed by DTE Energy, MichCon and Detroit Edison. Cautionary Note - The Securities and Exchange Commission permits oil and gas companies, in their filings with the SEC, to disclose only proved reserves that a company has demonstrated by actual production or conclusive formation tests to be economically and legally producible under existing economic and operating conditions. We use certain terms in this presentation such as "probable reserves" that the SEC's guidelines strictly prohibit us from including in filings with the SEC. You are urged to consider closely the disclosure in our Form 10-K and 10-Q, File No. 1-11607, available from our offices or from our website at www.dteenergy.com.

Unconventional Gas has a Lower Risk Profile Conventional Exploration and Production (E&P) risk includes the exploration risk of finding the reservoir The location of unconventional formations are typically well known and can exist over a large area, reducing the exploration risk Unconventional formations act as source, reservoir and seal After a test well phase to prove the economic viability of a given area, unconventional resources can be developed on a large scale Gas "manufacturing" Unconventional Conventional 2000 Investment in Coal Bed Methane

Unconventional Resources Are Present Throughout The U.S. Coal Bed Methane Tight Sand Shale DTE presently operates in the Antrim Shale and the Barnett Shale Currently, resource plays are a strong destination for onshore capital DTE has deep historical experience (15+ years) with unconventional gas DTE continues to evaluate other unconventional gas opportunities 2002 Initial investment in Barnett Shale Barnett Antrim

Why Unconventional Gas Production Makes Sense for DTE Energy Extension of a core business skill Deep historical experience (15+ years) with unconventional gas Expertise acquired through the MCN Energy merger Premium Returns Targeted ROIC of 15-20% for new investment Manageable risk Active in lower risk plays, not pursuing conventional E&P Lock in created value through hedges Take advantage of E&P value curve Potential partial monetization

Debt & Equity Equity Monetization Or Financing Structures May Provide Benefits For Managing The Growth Of The Unconventional Gas Business Monetization and financial structures may provide benefits to DTE: Provide capital to reinvest in the business Manage the size of the E&P assets within DTE Alternatives may include hold, sell or partial monetization The preferred structure would enable DTE to maximize the benefits (growth and finance structure of the E&P cycle) Area Maturity (Time) Low High High Low Mature Stage Middle Stage Early Stage THE E&P "VALUE CURVE" 1 2 3 4 5 6 Debt & Equity Risk Entry Cost

DTE Energy's Investment Thesis DTE Energy plans to create significant value for shareholders over the next five years The utilities are positioned to grow earnings 5-6% per year while driving a customer focused investment program Our three non-utility businesses have opportunities to grow earnings and increase cash flow The balance sheet is stable and we have sufficient flexibility to execute our plan The dividend yield is attractive, and as the payout ratio decreases, we are open to considering a dividend increase

Reconciliation of 2005 Reported Earnings to Operating Earnings Use of Operating Earnings Information - DTE Energy management believes that operating earnings provide a more meaningful representation of the company's earnings from ongoing operations and uses operating earnings as the primary performance measurement for external communications with analysts and investors. Internally, DTE Energy uses operating earnings to measure performance against budget and to report to the Board of Directors. = $345 total utility operating earnings

Reconciliations In this release, DTE Energy discusses 2006 operating earnings guidance. It is likely that certain items that impact the company's 2006 reported results will be excluded from operating results. A reconciliation to the comparable 2006 reported earnings guidance is not provided because it is not possible to provide a reliable forecast of specific line items such as 2007 oil hedging costs and other charges. These items may fluctuate significantly from period to period and may have a significant impact on reported earnings. 2006 Reported Earnings to Operating Earnings Throughout this presentation there are references to operating earnings, operating earnings in areas of expected future investment and illustrative profile of operating earnings for the years 2007 to 2010. These are not meant to constitute guidance, but rather are indicative of the long-term trends management currently expects from the business. It is likely that certain items that impact the company's reported results for those periods will be excluded from operating results. A reconciliation to the comparable reported earnings/net income amounts is not provided because it is not possible to provide a reliable forecast of specific line items such as oil hedging costs, Performance Excellence Process restructuring charges, impairments, and DTE2 implementation charges. These items may fluctuate significantly from period to period and may have a significant impact on reported earnings. Forward Looking Projections: 2007-2010
