Re:  MPSC Case No. U-12478
     Updated Securitization Bond Charge and Securitization Bond Tax Charge

Dear Ms. Wideman:

The Commission's November 2, 2000 order in Case No. U-12478 (Financing Order)
authorized the Detroit Edison Company following the sale of securitization
bonds, to bill its customers, an initial securitization charge of not more than
$0.004239 per kilowatt-hour and an initial tax charge of not more than $0.000766
per kilowatt-hour.

The Securitization Bonds were sold on March 9, 2001 and beginning March 26,
2001, Detroit Edison began billing a Securitization Bond Charge of $0.0032 per
kilowatt-hour and a Securitization Bond Tax Charge of $0.0005 per kilowatt-hour.

The purpose of this letter is to inform the Commission that Detroit Edison is
adjusting the Securitization Bond Charge to $0.0041 per kilowatt-hour and the
Securitization Bond Tax Charge to $0.0006 per kilowatt-hour beginning with bills
rendered on and after September 1, 2001. These adjustments are required to
ensure that the securitization charges will recover amounts sufficient to timely
provide all payments and other required amounts in connection with the
Securitization Bonds and to ensure recovery of the associated tax liability.

The new charges are less than those authorized by the Commission in its November
2nd order.

The change in the Securitization Bond Charge and Securitization Bond Tax Charge
will not impact the overall charge to our customers. For full-requirement
customers, the increase in charges will be offset by an equal and opposite
adjustment to base energy rates thereby preserving the rate freeze and the 5%
rate reductions mandated by PA 141. Electric Choice Customer's overall charge
remains unaffected due to the fact that, per the Commission's Order in Case No.
U-12478, prior to January 1, 2002, these customers are charged, on a net basis,
a transition charge equal to their bid participation charge.

Attachment A shows the values for each of the variables used in calculating the
updated Securitization Bond Charge and Securitization Bond Tax Charge. In a
separate letter to Mr. William Celio, Director - Electric Division, Detroit
Edison will submit updated tariff sheets necessary to implement these charge
updates.
