Item 8.01

Other Events.

          On April 25, 2006, the Delaware Public Service Commission (DPSC) issued a final order in the distribution base rate proceeding filed by Delmarva Power & Light Company (DPL), a subsidiary of Pepco Holdings, Inc., in September 2005. In its first comprehensive rate case in over ten years, DPL sought approval of an annual increase of approximately $5.1 million in its electric rates, consisting of an increase of approximately $1.6 million to its electric distribution base rates and the recovery of approximately $3.5 million (which amount was raised to $4.9 million as a result of subsequent filings in the case) in costs to be assigned to the supply component of rates collected as part of standard offer service (SOS). DPL's distribution revenue requirement in the application was based on a proposed return on common equity of 11%.

          The order of the DPSC approves a decrease in distribution rates of $11.1 million and a 10% return on equity. The order also modifies plant depreciation rates and adopts other miscellaneous tariff modifications. In addition, as requested by DPL, the order assigns $4.9 million in annual costs to the supply component of rates to be collected as part of SOS. DPL expects that the elements of the order, taken together, will have the effect of reducing DPL's annual net after-tax earnings and cash flow by approximately $1.6 million and $3.5 million, respectively.
