CenterPoint Energy Gas Transmission and Duke Energy Gas Transmission Sign Memorandum of Understanding Regarding a Major New Southeast Pipeline

HOUSTON -- CenterPoint Energy Gas Transmission Company, an indirect, wholly owned interstate natural gas pipeline subsidiary of CenterPoint Energy, Inc. and Duke Energy Gas Transmission, a subsidiary of Duke Energy Corp. announced today that they have executed a Memorandum of Understanding (MOU) to cooperate in the evaluation, marketing and development of a proposed pipeline connecting CEGT's Perryville Hub to DEGT's partially-owned affiliate pipeline, Gulfstream Natural Gas System. To assess the market interest in the proposed pipeline, an open season will be held in early December.

The capacity of the potential new pipeline would be between 700 million cubic feet per day and 1.0 billion cubic feet per day and would connect CEGT's Perryville Hub in northeast Louisiana to an interconnect with Gulfstream. The pipeline would be approximately 250 miles in length and could be in service as early as the Spring of 2008.

"We are pleased to be able to work with DEGT on a project of this magnitude. The new pipeline would provide our Perryville Hub customers access to additional markets," said Cy Zebot, senior vice president and chief commercial officer of CEGT. "In addition to our current customers, it would provide additional markets for Barnett Shale and Bossier Sand gas producers taking capacity on our recently announced Carthage to Perryville project. We believe the mutual interest of CEGT and DEGT expressed by the MOU is evidence of the superior value proposition represented by our highly liquid Perryville Hub, where numerous sources of supply can already access markets in the Midwest and Northeast, and now possibly in the Southeast, particularly Florida."

"A new pipeline system would provide customers with a competitive alternative to access growing, reliable onshore supply sources. It would also provide an important link for natural gas supply to reach key Northeast markets in winter, and rapidly-growing Southeast markets in summer," said Guy Buckley, DEGT's group vice president for US Southeast transmission. "We are excited to join CenterPoint Energy in this effort to ensure the energy needs of these growing markets are met."
