Alliant Acquires Mirant Plant

LCG, Feb. 4, 2002--A sales agreement made between Mirant Corp. and Alliant Energy Resources involving a 309-megawatt, gas-fired power plant has been finalized, the parties announced.

The plant, located in Neenah, Wisconsin, has a capacity of 309 megawatts, and has operated in simple-cycle mode since May 2000. Its output is sold under a power purchase agreement with WE Energies that lasts until June 2008.

The sale marks the first purchase of a power plant by Alliant Energy Generation, the Alliant Energy Resources subsidiary which since 2001 has been looking to acquire unregulated generating assets. Due diligence for the purchase was conducted by LCG Consulting, based in Los Altos, California.

"The successful closing of our first acquisition is a significant step in executing our unregulated generation strategy," Mike Maley, president of Alliant Energy Generation, stated.

Marce Fuller, president and chief executive officer of Mirant, noted that "This sale is an additional step in increasing our liquidity." The facility, which will be called Neenah Energy Facility, brought the company $109 million, with $300 million more in asset sales planned by the firm for this year.
