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 287-mile, 36-inch and 42-inch diameter pipeline with 1.09 Bcf/d 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 Enbridge Inc., 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 Enbridge Inc. and Enable Midstream. Enbridge Inc. is responsible for Gas Control and Commercial Operations, and CenterPoint Energy is responsible for Field Operations.
