RBN Energy is updating the natural gas storage buildout along the Gulf coast.  

Here's an excerpt with regard to Enbridge:

Next up is Enbridge, whose Gulf Coast gas storage assets include the Tres Palacios salt cavern facility in Matagorda County, TX (blue tank icon in Figure 2 above). When the company acquired Tres Palacios from Brookfield Infrastructure Partners and Crestwood Equity Partners in April 2023, it had three caverns with a combined capacity of 35 Bcf, plus an integrated 62-mile gas header pipeline system (blue line) with connections to 11 interstate and intrastate pipelines. In January, Enbridge brought online a fourth cavern that added 6.5 Bcf of capacity.

The midstreamer also holds an ownership interest in a 2-Bcf storage facility at the Waha Hub in West Texas (purple star) as well as full ownership of three other salt cavern facilities closer to the coast (orange stars): the 29-Bcf Bobcat site in St. Landry Parish, LA; the 22-Bcf Moss Bluff site in Liberty County, TX; and the 21-Bcf Egan site in Acadia Parish, LA.

Enbridge CEO Greg Ebel said in May that the company had recently concluded open seasons regarding possible expansions at Tres Palacios, Moss Bluff and Egan and “was engaging with customers around potential future growth opportunities.” In August, Enbridge Gas Transmission & Midstream President Cynthia Hansen added, “We're looking at whether, with the open season interest, we'll be expanding more at Tres, Moss and Egan. There’s a lot of obviously good opportunities in that area.”

Kinder Morgan has full or partial ownership stakes in more than 700 Bcf of gas storage capacity in the U.S., including more than 155 Bcf (light-blue tank icons in Figure 3 below) along or near the midstream giant’s Texas and Tejas intrastate pipeline systems (brown and purple lines) and NGPL interstate system (green lines). These include 99.4 Bcf at West Clear Lake, 27.8 Bcf at Markham Storage (expanded by 6 Bcf in June 2024), 11 Bcf at Dayton North, 9.6 Bcf at North Lansing, 1.4 Bcf at Stratton Ridge and (if you include West Texas) 6.4 Bcf at Keystone. Kinder also has 1.4 Bcf of storage (Bear Creek) in northern Louisiana along the Southern Natural Gas (SONAT) system (medium-blue tank icon and light-orange lines, respectively), in which it holds a 50% stake.
