Distribution Rate Case Settlement

     On September 14, 2006, Duquesne Light Holdings, Inc.’s wholly owned subsidiary, Duquesne Light Company (“DLC”), entered into, and filed with the Pennsylvania Public Utility Commission (“PaPUC”), a Joint Petition of Settlement among all parties resolving all issues in the distribution rate case DLC filed with the PaPUC in April 2006.

     The settlement provides for (i) a distribution rate increase of $117 million in annual operating revenues, and (ii) an automatic pass-through for charges that DLC will pay for transmission services it purchases under tariffs regulated by the Federal Energy Regulatory Commission.

     The settlement agreement has been submitted to the administrative law judge presiding over the rate case. Final effectiveness of the settlement is subject to (i) the administrative law judge’s review and recommendation and (ii) PaPUC review and approval. A final order is anticipated in the fourth quarter of 2006; however, DLC cannot predict the ultimate timing or outcome of these proceedings.
