REGULATION FD DISCLOSURE. In connection with the matter described in Item 8.01, DTE Energy Company ("DTE Energy") is furnishing the Securities and Exchange Commission ("SEC") with its press release issued by May 15, 2006, which announced that it is maintaining its operating earnings guidance, excluding Synfuels. A copy of the press release is furnished as Exhibit 99.1 and incorporated herein by reference. In accordance with General Instruction B.2 of Form 8-K, the information in this Current Report on Form 8-K under Item 7.01., including Exhibit 99.1, shall not be deemed "filed" for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, except as shall be expressly set forth in such a filing. ITEM 8.01. OTHER EVENTS DTE Energy today announced it idled production at all nine synthetic fuel ("synfuel") facilities operated by the company. The decision to idle synfuel production was driven by the current level and volatility of oil prices and the lack of federal legislation that would have provided certainty for production economics this year. Synthetic fuel production may resume, depending on various factors, including a reduction in oil prices or the enactment of potential federal legislation. DTE Energy retains production flexibility that could allow it to make up lost production during the remainder of 2006 if the current shutdown remains limited in duration. DTE Energy holds a majority interest in two of the nine synthetic fuel production facilities and minority interests in the remaining seven facilities. Synthetic fuel facilities chemically change coal, including waste and marginal coal, into a synthetic fuel as determined under applicable Internal Revenue Service (IRS) rules. The production and sale of synthetic fuel produced at these facilities generates production tax credits under the Internal Revenue Code. The value of these credits is dependent on the full-year average price of oil for the year in which the credits are generated. While the full-year average price of oil cannot be known with certainty prior to the end of the year, current high oil prices suggest that credits' value could be partially or fully phased out for 2006. Legislation was proposed in Congress for inclusion in the recent tax reconciliation bill that would have impacted the potential phase-out of production tax credits for 2006 and 2007. However, this provision was not included in the reconciliation bill as enacted. The proposed legislation is under consideration for inclusion in subsequent legislation, such as the "extenders" bill. If included and enacted as proposed, then there would be no phase-out of tax credits for 2006 and DTE Energy could resume production at the synthetic fuel facilities it operates.
