"This acquisition in combination with our recently deregulated Ohio generation and the peakingcapacity added early this year creates for Cinergy a significant and balanced generation portfolio ofbaseload and peaking capacity," said James E. Rogers, president and chief executive of Cinergy Corp.

The acquisition consists of Enron's 494 megawatt Brownsville generation facility located inHaywood County, Tennessee and the 504 megawatt Caledonia generation facility located inLowndes County, Mississippi, both of which entered into service in June 1999.

Both facilities are located in the Southeastern Electric Reliability Council region and are interconnected to the Tennessee Valley Authority transmission system.

The completion of the acquisition is subject to, among other things, receipt of approval of theFederal Energy Regulatory Commission and expiration of the waiting period under theHart-Scott-Rodino Antitrust Improvements Act of 1976. Cinergy said it expects that regulatoryapprovals would be obtained and the transaction will close in the spring of next year.
