Our two interstate natural gas pipelines, CenterPoint Energy Gas Transmission Company and CenterPoint Energy - Mississippi River Transmission Corporation, operate pipelines in Arkansas, Illinois, Louisiana, Missouri, Oklahoma and Texas.

CenterPoint Energy has completed or is nearing completion of two new, substantial pipeline projects:

• Carthage to Perryville
  Carthage to Perryville, which went into service in May 2007, connects new domestic natural gas supplies in the East Texas area to markets in the Midwest and Northeast. The pipeline has approximately 1.5 billion cubic feet (Bcf) per day of capacity, which will be boosted to approximately 1.9 Bcf per day in the second quarter of 2010.
• Southeast Supply Header
  The Southeast Supply Header is a joint project with Spectra Energy Corp. The pipeline, which went into service in September 2008, has approximately 1.0 Bcf per day of pipeline capacity and extends from CenterPoint Energy's Perryville Hub in northeast Louisiana to Spectra's partially owned affiliate pipeline, Gulfstream Natural Gas System in Mobile County, Alabama.
