Southeast Supply Header, LLC (SESH) links the onshore natural gas supply basins of east Texas and northern Louisiana to Southeast markets now predominantly served by offshore natural gas supplies from the Gulf of Mexico. SESH provides customers with a reliable alternative to offshore supply, which can be vulnerable to weather-related disruptions. The 274 mile, 36-inch and 42-inch diameter pipeline with 1.0 Bcf of capacity extends from the Perryville Hub in northeastern Louisiana to the Gulfstream Natural Gas System, L.L.C. pipeline system, which is 50 percent owned by an affiliate of Spectra Energy, in southern Mobile County, Alabama. SESH interconnects with a variety of interstate natural gas pipelines, providing additional opportunities for supply to reach key southeast and northeast markets, as well as several high-deliverability storage facilities.

SESH is a joint venture between subsidiaries of Spectra Energy Corp and CenterPoint Energy, Inc. Spectra Energy Transmission is responsible for Gas Control and Commercial Operations, and CenterPoint Energy is responsible for Field Operations.
