Utility and FERC Attempt to Block Moves by Bankrupt Mirant

LCG, Sept. 5, 2003--Mirant Corp. is attempting to cancel $700 million worth of money-losing power supply contracts it signed with Pepco, a utility serving Washington, DC and surrounding areas, while Pepco and the Federal Energy Regulatory Commission say that the bankruptcy court overseeing Mirant's reorganization lacks the proper authority to allow such a move.

Mirant, having filed for bankruptcy on July 14, requested that the bankruptcy court allow it to be released from deals in which it sold power to Pepco from plants formerly owned by Pepco, as well as from existing purchase agreements it acquired from the utility. FERC officials, having filed jointly with the U.S. District Court for Northern Texas U.S. on the matter, contend that only FERC should be able to release Mirant from contracts.

A temporary restraining order was issued by the bankruptcy court that barred FERC from issuing any orders concerning Mirant's deals with Pepco. It does not appear likely that, whatever the outcome, Pepco will need to consider the possibility of losing its power supply. Mirant wishes to renegotiate its existing deals. Several deals it is trying to revise are with companies other than Pepco, such as a tolling agreement with a 725-megawatt plant in Texas, Cleco's Perryville. Cleco has said it will seek damages if the contract is cancelled by the bankruptcy court.
