Mirant Buys Two Southeast U.S. Plants from El Paso

LCG, Aug. 9, 2001--Mirant Corp. said yesterday it has agreed with El Paso Corp. on the purchase of two power plants with a combined capacity of 1,120 megawatts in the U.S. Southeast for $330 million.

Mirant will acquire El Paso's 640 megawatt natural gas-fired power plant in Thomaston, Ga., and its480 megawatt gas-fired plant in New Port Richey, Fla., north of Tampa, the companies said in a jointstatement.

The Thomaston plant has been in commercial operation since June of last year, while the New Port Richey plant is schedule to begin production next March. Mirant will provide power from the plants under several of purchase agreements already in place, the company said.

"We see this asset combination as a great opportunity to participate in two of the fastest growing markets in the country," said David Rozier, chief executive of Mirant's southern U.S. operations. "These acquisitions provide a clear complement to Mirant's fully integrated asset, marketing and risk management capabilities."

A Mirant spokesman said the transaction would involve the assumption of $150 million in debt, and added that the company expected to close the agreement in early October, after getting regulatory and certain third party approvals.

"This transaction enables El Paso to optimize the value of these assets while redeploying the capital to our growing and diverse power generation portfolio," said Clark C. Smith, president of El Paso Merchant Energy-North America. "We will continue to pursue greenfield power development and acquisition opportunities in strategic locations across North America."
