Item 8.01. Other Events

As a result of the Electric Service Customer Choice and Rate Relief Law of 1997, the Illinois General Assembly provided the opportunity for power suppliers to compete to supply power to Illinois electric utilities to meet the full requirements of all non-shopping Illinois electricity customers. The Illinois Commerce Commission (ICC) conducted an auction for supply of up to 25,474 MW of peak load and hired an independent Auction Monitor for this purpose. PPL EnergyPlus, LLC, the energy marketing subsidiary of PPL Corporation (PPL) and PPL Energy Supply, LLC, submitted bids in this Illinois auction process and, as a result, in September 2006 entered into three agreements with Commonwealth Edison Company to supply a portion of its full requirements service. These agreements commenced in January 2007 and expire after 17, 29 and 41 months. During peak hours, PPL EnergyPlus’ obligation to supply Commonwealth Edison may reach 700 MW. At the conclusion of the auction process, the Auction Monitor and the ICC Staff both concluded that the auction process was competitive.

On March 15, 2007, the Illinois Attorney General filed a complaint at the Federal Energy Regulatory Commission (FERC) against all of the successful bidders in this auction process, including PPL EnergyPlus and fourteen other suppliers, alleging market manipulation and requesting that FERC investigate such allegations, requesting refunds for sales at prices above just and reasonable rates and seeking revocation of FERC market-based rate authority for certain of the suppliers. The redacted copy of the complaint served on PPL EnergyPlus does not identify which suppliers allegedly engaged in market manipulation or which suppliers allegedly should have their market-based rate authority revoked.

PPL EnergyPlus is reviewing the complaint and gathering information regarding the allegations. While PPL and PPL Energy Supply do not currently believe that this matter will have a material adverse impact on the financial condition of PPL and PPL Energy Supply, they cannot predict the outcome of this matter.
