The Carthage to Perryville pipeline is owned and operated by CenterPoint Energy Gas Transmission Company (CEGT). The pipeline, placed in service in May 2007, has created approximately 1.5 billion cubic feet (bcf) per day of pipeline capacity and has connected new domestic natural gas supplies in the East Texas area to markets in the Midwest and Northeast.

The 172-mile pipeline consists of 42-inch diameter pipe from Carthage, Texas, to Delhi, Louisiana, and two compressor stations totaling 41,240 horsepower. The pipeline connects multiple East Texas receiving points with CEGT's Perryville Hub and four new interstate pipeline interconnections.
