      Applicant DTE Energy Company (“DTE Energy”) files this second post-effective amendment solely to request authorization through September 1, 2001, to carry out the transactions authorized in Holding Company Act Release No. 27229 (September 13, 2000), and therefore amends the Application in this file, as previously amended, by adding at the conclusion of Item 5, Procedure, the following sentence:

      “In order to allow for transactional and documentation contingencies and delays that would make it impracticable to complete the transactional steps authorized herein as promptly as anticipated or at substantially the same time, DTE Energy requests that it be authorized through September 1, 2001, to complete the transactions described herein.”

      Applicant further amends the foregoing application by striking the last sentence of Item 3 and substituting therefore the following:

      “Within six months of the asset transfer to ITC pursuant to Commission approval of this Application, Detroit Edison must file an application with the MPSC seeking approval of the proposed accounting treatment for the Transfer Transaction.”

      Applicant further amends the foregoing application by deleting subsection C of Item 4 and redesignating subsection D of Item 4 as subsection C of Item 4.

      In support of the foregoing amendment, Applicant states that unanticipated complexities pertaining to the due diligence associated with the transaction authorized by this Application prevented completion of the transaction within sixty (60) days. Applicant further states that no change in the substance of the Application is either requested or required in order to complete the transaction described in the Application, including, without limitation, Item 2, Fees, Commissions, and Expenses. Applicant further shows that the changes to Item 3 and Item 4 merely reflect the fact that the anticipated accounting filing is still timely under Michigan law and the fact that no action was required from the Nuclear Regulatory Commission.
