COLUMBUS, Ohio, April 1, 2004 - American Electric Power (NYSE: AEP) today announced that it has completed the $76.2 million sale of LIG Pipeline Co. and its subsidiaries to Crosstex Energy, L.P., through its subsidiary, Crosstex Louisiana Energy, L.P.

The companies announced the transaction on Feb. 17.

The LIG transaction is part of AEP´s divestiture of assets that don´t align with the company´s long-term strategy. Proceeds from the sale will be used to reduce debt and strengthen the balance sheet. The sale of LIG is not expected to have a material impact on 2004 GAAP earnings.

The sale includes approximately 2,000 miles of natural gas gathering and transmission pipelines in Louisiana and five gas processing facilities that straddle the system.

AEP continues progress on the planned divestiture of Jefferson Island Storage and Hub L.L.C., which was acquired with the LIG assets by AEP in 1998 but will be sold separately. Jefferson Island Storage and Hub consists of two salt dome gas storage caverns, with approximately 9 million MMBtu of storage capacity, and two 16-inch header pipelines.

American Electric Power owns and operates more than 42,000 megawatts of generating capacity in the United States and select international markets and is the largest electricity generator in the U.S. AEP is also one of the largest electric utilities in the United States, with more than 5 million customers linked to AEP’s 11-state electricity transmission and distribution grid. The company is based in Columbus, Ohio.
