Enbridge In The Permian -- RBN Energy -- October 26, 2026

RBN Energy: this RBN Energy blog is about the Permian, but because Enbridge is featured in the article and Enbridge is a big player in the Bakken, I'm reposting the link and the bit about Enbridge.

Link here to RBN Energy: why brownfield projects have an edge in the ongoing Gulf Coast gas storage buildout.

There’s a horse race among Gulf Coast gas storage developers to provide the tens of billions of cubic feet of incremental space that will be needed by the early 2030s. Out front are the owners of existing salt cavern storage, whose brownfield expansions almost always offer better economics than their greenfield competitors. But which brownfield projects have that special something — an advantageous site, better pipeline connectivity, or higher injection and withdrawal rates — that gives them a critical edge? In today’s RBN blog, we continue our series on Gulf Coast gas storage by looking at a few leading brownfield projects.

Enbridge

Enbridge’s incremental capacity is divided among three projects. The largest is a three-cavern, 25-Bcf expansion at the company’s Tres Palacios facility in Matagorda County, TX. When Enbridge acquired Tres Palacios (light-blue dome icon in Figure 1 below) in April 2023, it had three caverns with a combined capacity of 35 Bcf; in December 2024, Enbridge brought online a fourth cavern that added 6.5 Bcf.

In May, Enbridge announced that “Tres Palacios will soon have tres nuevas cavernas.” The three new caverns will have a combined capacity of 25 Bcf, increasing the facility’s capacity to more than 66 Bcf and boosting its total injection and withdrawal rates to 1.65 Bcf/d and 2.5 Bcf/d, respectively. The $400 million expansion will be completed in phases, with new capacity coming online between 2028 and 2030. Tres Palacios also features a 62-mile header system (light-blue line) that interconnects with 13 major pipelines, including Enbridge’s own Texas Eastern Transmission Co. (TETCO) system.

And there’s this: On July 31, Enbridge announced that it had signed an exclusive option to acquire the TTC Connector (dashed medium-blue line), a 25-mile, 300-MMcf/d pipeline now under construction between Tres Palacios and Boardwalk Pipeline Partners’ Coastal Bend Header (dark-blue line), which runs to the Freeport LNG export terminal. Enbridge is expected to take ownership of the 20-inch-diameter TTC Connector when it starts up in Q4 2026. BP, a major offtaker at Freeport LNG, has contracted for all of the TTC Connector’s capacity.

Enbridge also is in the midst of expansions at its 22-Bcf Moss Bluff gas storage facility (purple dome icon) in Liberty County, TX, and its 21-Bcf Egan facility (magenta dome icon) in Acadia Parish, LA, which straddle the existing and planned LNG terminals along the Sabine-Neches and Calcasieu waterways and are connected to the TETCO system and several other pipelines. Enbridge announced in November 2025 that it had taken FID on a 7-Bcf expansion at Moss Bluff that will come online in 2028 and a 16-Bcf expansion at Egan that will start up in two phases in 2030 and 2033, respectively.

We should note that Moss Bluff has a 23-mile header system that interconnects with five major pipelines and can inject up to 600 MMcf/d and withdraw up to 1.2 Bcf/d. Egan, in turn, has a 56-mile header that interconnects with nine pipelines, can inject more than 1 Bcf/d (and nearly 1.6 Bcf/d when the expansion is finished) and withdraw up to 2.7 Bcf/d.

[Enbridge also owns the 29-Bcf Bobcat salt cavern storage facility (pink dome icon) in St. Landry Parish, LA, and a 2-Bcf salt cavern facility near the Waha gas hub in West Texas (not shown).]
