Enterprise Announces New Long-Term Natural Gas Transportation and Storage Contracts with CenterPoint Energy in Texas.

HOUSTON -- Enterprise Products Partners L.P. (NYSE:EPD) announced today that it is expanding its leading position in the Texas intrastate natural gas market by signing long-term agreements with CenterPoint Energy Resources Corp. (CERC) to provide firm natural gas transportation and storage services to its natural gas utility, primarily in the Houston metropolitan area. CERC is a subsidiary of CenterPoint Energy, Inc. (NYSE:CNP). Enterprise, owner and operator of one of the largest natural gas pipeline systems in Texas, will provide CenterPoint Energy with up to fourteen billion cubic feet ("Bcf") per year of natural gas service beginning in April 2007. Enterprise's deliveries to CenterPoint Energy through these new contracts marks the first time that Enterprise, the primary natural gas service provider to the San Antonio and Austin markets, has had the opportunity to serve the growing Houston area distribution market. E[acute accent]To provide the new services, Enterprise will enhance its Texas intrastate pipeline system through a combination of pipeline and compression projects, expand its natural gas storage facilities in Texas, acquire certain pipeline laterals located in the Houston area and construct eleven new city gate delivery stations to CenterPoint Energy. The total capital cost of these projects is estimated to be approximately $100 million and will be completed in phases throughout 2006 and 2007. The project is designed to provide CenterPoint Energy with access to growing natural gas supplies from multiple producing regions in Texas and positions Enterprise for further gains in market share in the future. Enterprise currently delivers approximately 146 Bcf per year of natural gas supplies to industrial, commercial and power plant users in the Houston Ship Channel market, which is one of the largest natural gas consuming markets in the U.S. E[acute accent]"Expanding our pipeline system in this key market area highlights our long-term commitment to provide CenterPoint Energy access to flexible and reliable natural gas supplies for its growing customer base in the Greater Houston area," said Robert G. Phillips, Enterprise's President and Chief Executive Officer. "These new contracts confirm the attractiveness of the Enterprise Texas pipeline system, which is well positioned to gather, process and deliver increased natural gas production to our market area customers from the Barnett Shale, Permian basin and emerging new development plays in South Texas." E[acute accent]Enterprise has one of the largest natural gas pipeline systems in Texas with over 8,200 miles of pipe that access major supply basins in North Texas (Barnett Shale), East Texas (Bossier), South Texas (Wilcox and Vicksburg) and West Texas (Permian). It is also connected to all major Texas markets including the cities of San Antonio, Austin, Dallas Fort Worth, Beaumont, Corpus Christi, Houston and the Houston Ship Channel area, as well as 19 natural gas-fired power plants. Enterprise has 10 natural gas processing plants in Texas with the capacity to process two billion cubic feet per day of natural gas. Total throughput on the Texas pipeline system was approximately 3.4 BBtu/d in the first half of 2006. E[acute accent]Recently, Enterprise extended its pipeline system in South Texas through the purchase of the Cerrito natural gas gathering system in South Texas for $325 million. This acquisition provides Enterprise processing plants with a long-term source of rich natural gas production and provides markets in Texas with access to a growing source of pipeline quality residue gas. Additionally, Enterprise recently completed an expansion of its 30" West Texas pipeline system, for approximately $27 million, which provides 120 MMcf/d of new capacity to bring increasing Barnett Shale and Permian basin production into the Central Texas and Gulf Coast markets.
