Cheniere’s Corpus LNG advances toward massive capacity boost

(The Center Square) - Federal regulators on Friday issued a draft Environmental Impact Statement for a proposed expansion at the Corpus Christi LNG terminal, advancing a project that could boost American export capacity by 24 million tons per year.

The draft report, released by the Federal Energy Regulatory Commission, moves Cheniere Energy’s Stage Four expansion projects toward a final investment decision expected in the second half of 2027.

At the company’s existing 1,000-acre site in San Patricio County, Cheniere’s planned Stage Four expansion projects would add four high-capacity production trains, a 25.8-mile-long pipeline, and a third marine berth extending into the waters of Nueces County.

Houston-based Cheniere’s planned 24-million-ton-per-year Stage Four increase would add significantly to American LNG export capacity, which totaled about 111 million tons in 2025. When Stage Three went into production in late-August 2026, the Corpus Christi LNG plant’s annual capacity reached approximately 25 million tons.

The draft permit comes as global LNG supplies remain tight following Iranian missile attacks on Qatar and the United Arab Emirates in March. Those strikes closed the Strait of Hormuz, cutting off a shipping corridor that carries about one-fifth of the global LNG exports to buyers mostly in Asia and Europe.

Cheniere filed its application at the Federal Energy Regulatory Commission to build Stage Four on Feb. 26 – just days before the U.S.-Israel war with Iran began – with backing from Taiwan’s state-owned CPC Corporation. Taiwan imports about 97% of its energy and depends heavily on LNG to keep its high-tech semiconductor chips manufacturing plants running.

On Feb. 26, the day Cheniere signed the supply agreement with CPC and filed an application for the Stage Four expansion, U.S. Energy Secretary Chris Wright told workers during a tour of the Corpus Christi LNG export plant that "every new train you build" improves lives around the world. Texas Republican Sen. Ted Cruz said Texas has the capacity to produce enough LNG to "literally power the world."

A day later, President Donald Trump visited the Port of Corpus Christi to champion his "American Energy Dominance" agenda. “We're unleashing America's potential, strengthening our security, increasing our prosperity, and cementing America's status as the number one energy superpower anywhere on Earth,” the president said in a speech on Feb. 27.

The Stage Four expansion would put the Corpus Christi plant on track to become the third-largest LNG export facility in the world by 2031. Other major expansions are now underway at the Venture Global CP2 LNG plant, which would take production to 60-million-tons-per-year in 2031, while near the same time total output at Cheniere's own Sabine Pass terminal is expected to reach 50 million tons per year.

A final approval will require that Cheniere adopt site-specific mitigation measures to minimize impacts on local air quality, wetlands, and noise levels before construction can legally begin.

The federal comment period is open through Nov. 9.
