Energy Transfer commits $1.6 billion to build South Mississippi Pipeline

What the project is

Energy Transfer said Tuesday it will construct the South Mississippi Pipeline and plans to operate it. The route spans 215 miles, also described as 346 kilometers, carrying supply that begins in eastern Louisiana and crosses Mississippi.

The system's capacity tops out at 1.2 billion cubic feet a day. Energy Transfer plans to be the operator and hold a 51% interest, while customers would own the remaining stake. The company said the pipeline will "give shippers greater access to natural gas from multiple basins across the southeastern US."

Why they are building it

Pipeline developers are racing to add capacity as gas consumption climbs, helped by liquefied natural gas facilities along the Gulf Coast and new generation built to power AI data centers. That construction boom is prompting worries that the surge in data centers could negate about 15 years of emissions progress from US power generation.

Energy Transfer is taking commitments now, with a binding open season that ends Nov. 25. The company targets an in-service date in 2030.

Related moves and what to watch

Energy Transfer also installed equipment to increase flows on its Rover Pipeline in the Midwest, with that expansion scheduled to begin service on Nov. 1. In addition, the company signed two agreements to deliver a daily total of 150,000 million British thermal units to two Missouri power plants that are under construction.

The bottom line: more pipes mean more optionality for shippers and potentially steadier feedstock for LNG and data centers. If demand holds, transport volumes and fee-based cash flows matter for your portfolio exposure to midstream names.
