Enbridge has signed an exclusive option to acquire the TTC Connector, a roughly 40-kilometre pipeline under construction in Texas that will move up to 300 million cubic feet of natural gas per day between the company's Tres Palacios storage hub and the Freeport LNG export terminal on Quintana Island. The line is scheduled to enter service by the end of 2026.

The agreement gives the Canadian midstream operator a direct seat on the last-mile link between its Texas storage base and one of the largest operating LNG export facilities in the United States.

What does the TTC Connector add to the chain?

The TTC Connector will run from Tres Palacios to the Coastal Bend Header pipeline, tying Enbridge's intrastate system into the corridor that feeds the Freeport LNG facility. Freeport LNG has the capacity to handle approximately 2.23 billion cubic feet of gas per day, equivalent to about 17 million tonnes of LNG per year.

Enbridge gas transmission executives frame the line as a last-mile connector rather than a long-haul pipe. Elizabeth Perez, director of Intrastate Business Development at Enbridge Gas Transmission, called it "a last-mile LNG supply project," and pointed to the broader convergence of storage, pipeline and export assets along the Texas coast.

The connector sits inside a regional build-out that Enbridge is pursuing in parallel with the Tres Palacios expansion. Matthew Akman, executive vice president and president of Enbridge's gas transmission business, highlighted that the company has nearly 50 billion cubic feet in expansion projects within its own Gulf Coast storage facilities — a footprint that anchors the rationale for owning the connector.

Why does Freeport LNG matter for Tres Palacios?

Freeport LNG occupies a strategic slot among US export terminals. The Quintana Island facility is among the largest operating liquefaction sites in the United States. Tres Palacios has historically fed third-party gas buyers and utility markets; tying it more directly to Freeport shifts part of the storage base toward the export market.

A dedicated 300 MMcf/d pipeline gives Freeport another storage-backed supply stream rather than relying solely on header deliveries, while giving Enbridge a captive offtake path for its expanded Tres Palacios volumes.

How much storage is Enbridge adding on the Gulf Coast?

Enbridge already controls roughly 10% of available natural gas storage capacity on the US Gulf Coast. Three working-gas expansions will add approximately 50 Bcf of incremental capacity across the company's footprint:

• Egan, Louisiana: +16 Bcf
• Moss Bluff, Texas: +7 Bcf
• Tres Palacios: +25 Bcf

Combined with existing capacity, Enbridge projects its four Gulf Coast storage facilities will reach approximately 150 Bcf by 2033. Tres Palacios is the largest of the three announced expansions and the one that physically underpins the TTC Connector economics.

What is the next operational milestone?

Two dates frame the procurement record. The end-of-2026 TTC Connector in-service target is the first, and the most consequential for near-term flows. The second is the 2033 storage buildout horizon, which will determine whether Enbridge expands the Tres Palacios-to-Freeport pathway with additional pipe or relies on the existing 300 MMcf/d link.

The commercial conversion of Enbridge's exclusive option into a binding acquisition is the interim watch item. Until that closes, the Tres Palacios volumes will continue to move to Freeport via third-party header capacity under existing arrangements.
