Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions:

DTE Energy Company (DTE Energy) is furnishing the Securities and Exchange Commission (SEC) with its earnings release issued April 27, 2012, announcing financial results for the quarter ended March 31, 2012. Copies of the earnings release and the financial information distributed for media and investor relations communications are furnished as Exhibits 99.1 and 99.2 and incorporated herein by reference.

DTE Energy is furnishing the SEC with its slide presentation issued April 27, 2012. A copy of the slide presentation is furnished as Exhibit 99.3 and incorporated herein by reference.

In its earnings release, slide presentation and this filing, DTE Energy discusses 2012 operating earnings guidance. It is likely that certain items that impact the company’s 2012 reported results will be excluded from operating results. Reconciliations to the comparable 2012 reported earnings guidance are not provided because it is not possible to provide a reliable forecast of specific line items. These items may fluctuate significantly from period to period and may have a significant impact on reported earnings.

In accordance with General Instruction B.2 of Form 8-K, the information in this Current Report on Form 8-K, including Exhibits 99.1 and 99.2 and 99.3, 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.
