Texas Eastern Line 31 Expansion Project

With the growing demand for reliable energy sources with lower emissions, Texas Eastern Transmission, LP (Texas Eastern) is proposing an expansion of its interstate natural gas pipeline system in Mississippi called the Texas Eastern Line 31 Expansion Project.

The scope includes the installation of approximately 10.2 miles of 36-inch diameter pipeline looping the existing pipeline, 1.7 mile, 16-inch diameter delivery lateral to connect with Entergy’s proposed Ridgeland Advanced Power Station in Madison County. Additionally, Texas Eastern will construct a compressor station called the Ridgeland Compressor Station in Madison. The Line 31 Expansion Pipeline will expand Texas Eastern’s existing pipeline system capacity to provide the additional gas required to serve both existing and future downstream customers.

The Project will provide up to 125,000 dekatherms per day (Dth/d) of additional natural gas transportation capacity on the Texas Eastern system.

All necessary regulatory authorizations from the Federal Energy Regulatory Commission (FERC) and other federal and state agencies are required before construction of the project can commence. Pending the approval and receipt of all necessary permits, construction would begin in August 2027 with a target in-service date of September 2028.
