Exelon Buys 2 Texas Power Plants from TXU

LCG, Dec. 20, 2001--Exelon Corp. and TXU Corp. announced jointly this morning that TXU will sell two large natural gas-fueled power plants in the Dallas-Fort Worth area to Exelon Generation for $443 million. Combined capacity of the plants is 2,334 megawatts.

"This transaction is yet a further example of the execution of TXU's portfolio management business model," said Brian Dickie, North American president of TXU Energy. "It decreases our size in the Texas generation market, reduces debt and positions TXU for further growth in other U.S. markets. It is also good for Texas customers as it retains reliability and promotes competition."

The two plants are the 893 megawatt, five-unit Mountain Creek station in Dallas and the 1,441 megawatt, five-unit plant in Fort Worth.

"These plants represent a good fit with Exelon's plan to grow its portfolio of generation assets and to use them to position Exelon as one of the nation's top tier energy suppliers," said Christine Jacobs, president of Exelon Power. "The plants are situated in a region of large and ever- increasing demand. The transaction is immediately accretive to earnings and triples the amount of our generation in the region, allowing us to become a more effective competitor."

Both companies said the labor forces at the two plants will be undisturbed for at least two years.

"It is clear that these plants are valuable and their staffs are well- trained and professional," Exelon's Jacobs said. "They will make a welcome addition to our operation."
