Feed gas demand was disrupted at the Freeport liquefied natural gas (LNG) terminal in Texas last week after the facility reported an outage to state regulators.

The LNG terminal east of Houston, on Quintana Island near Freeport, experienced an outage at the Train 1 liquefaction unit last week.

The outage led to a cooldown and restart of equipment and gas flaring, which took nearly 10 hours to resolve, according to documents submitted to the Texas Commission on Environmental Quality.

“During operation of Freeport LNG’s liquefaction plant, the facility experienced a trip of the liquefaction Train 1” after the anti-surge valve on the mixed refrigerant compressor “went wide open,” according to the report by company engineers.

Scheduled deliveries to Freeport LNG from the Gulf South and Texas Eastern Transmission Co. pipelines from Jan. 12-13, the day of the incident, dropped more than 483,000 Dth, according to NGI’s U.S. LNG Export Tracker. It was the first day NGI’s tracker recorded a negative change in deliveries since Jan. 6.

On Jan. 14, deliveries and capacity utility were reported at almost the exact same levels as Jan. 12, according to NGI data. Freeport LNG saw 2.188 million Dth in feed gas deliveries Tuesday (Jan. 18). Overall U.S. deliveries were down 588,147 Dth compared to Monday.

EBW Analytics Group early Tuesday predicted that the outage could trigger a reduction in feed gas demand later in the month. EBW analysts estimated that U.S. feed gas flows hit a record of 13.2 Bcf/d on Sunday (Jan. 16), but they had already declined by 0.8 Bcf/d early Monday.

The first liquefaction train at Freeport began commercial service at the end of 2019, with the second train ramped up in early 2020. A third train came online in May 2020.

The company has moved expectations for a final investment decision for a fourth train to later this year, with a start-up possibly in 2026. Train 4 would expand the overall export capacity by 5 million metric tons per year (mmty), boosting overall output to more than 20 mmty.
