The Offering The following summary contains basic information about our common stock and this offering and is not intended to be complete. It does not contain all the information that is important to you. For a complete understanding of our common stock, you should read the section of the accompanying prospectus entitled “Description of Capital Stock.”

| Issuer | DTE Energy Company, a Michigan corporation |

| Common Stock Offered | Shares of our common stock, without par value, having aggregate gross sales proceeds of up to $1,500,000,000. |

| Use of Proceeds After Expenses | We intend to use the net proceeds (i) from this offering, after deducting Managers’ commission and our offering expenses and (ii) payable upon settlement of any forward sale agreement, in each case, for general corporate 
 purposes, which may include investments in our subsidiaries. See “Use of Proceeds.”                                                                                                                                          |

| Conflicts of Interest | The Forward Purchasers (or their respective affiliates) will receive the net proceeds of any sale of borrowed shares of our common stock sold pursuant to this prospectus supplement in connection with any forward sale agreement. In addition, the      
 net proceeds from the sale of shares of our common stock in this offering may be used to repay borrowings under our revolving credit agreement (as defined herein) or to repay our or our subsidiaries’ outstanding commercial paper borrowings.          
 Because certain Managers, Forward Sellers and Forward Purchasers (or their respective affiliates) are expected to receive part of the net proceeds from the sale of shares of our common stock in connection with any forward sale agreement, and because 
 certain Managers, Forward Sellers and Forward Purchasers (or their respective affiliates) are lenders under our revolving credit agreement or may hold some of our or our subsidiaries’ outstanding commercial paper and therefore may receive part       
 of the net proceeds of this offering in the event any of the net proceeds is used to repay any such borrowings, any such Manager, Forward Seller or Forward Purchaser would be deemed to have a conflict of interest under Rule 5121 of the Financial     
 Industry Regulatory Authority, Inc. (“FINRA Rule 5121”) if such Manager, Forward Seller or Forward Purchaser
