Sempra Extends ECA LNG Commissioning After First-Cargo Shutdown
Mexico's first Pacific Coast LNG terminal entered an extended commissioning pause after its July maiden cargo, delaying commercial operations for Sempra and TotalEnergies.
Sempra has extended the commissioning process for its ECA LNG Phase 1 terminal in Ensenada, Mexico, after the plant was shut down for planned inspections following its maiden cargo in early July (2026-07-08), Rigzone reported on August 4 (2026-08-04).7
The delay pushes back the timetable for commercial operations at Mexico's first LNG export terminal on the Pacific Coast — a project TotalEnergies has structured around a 20-year offtake agreement to purchase 1.7 million tonnes per annum once that status is formally declared.2,5
ECA LNG Phase 1 loaded and shipped its inaugural cargo on July 8 (2026-07-08), with Sempra Infrastructure announcing the milestone in a press release the same day. TotalEnergies confirmed on July 9 (2026-07-09) that the cargo had departed for Asia. The French major is the sole LNG offtaker during the ramp-up phase, meaning all commissioning cargoes move under its name.4,3,6
TotalEnergies holds a 16.6% equity stake in ECA LNG Phase 1 alongside operator Sempra Infrastructure. The ramp-up structure, with TotalEnergies as exclusive buyer, was designed to allow the plant to demonstrate stable throughput before the 20-year contract clock formally starts. Under that deal, TotalEnergies will lift 1.7 Mtpa for two decades once commercial operations are declared.2,5
The project is built around a single liquefaction train with a nameplate capacity of 3.25 million tonnes per annum, smaller than the individual trains at US Gulf Coast export facilities. Its commercial case rests on geography: the Baja California location offers a Pacific crossing to Asian buyers that avoids the Panama Canal and cuts transit time compared with Gulf departures.1,2,5
Those economics are visible in current market pricing. JKM, the Asian LNG benchmark, was priced at $22.08/MMBtu in August 20 (2026-08-20) trading, with NYMEX Henry Hub front-month settling at $2.76/MMBtu in the same session. The spread between US domestic gas and Asian delivered prices creates incentive for Pacific Basin-oriented exports, but only once a terminal is producing steadily.2,5
Sempra first confirmed LNG production at ECA Phase 1 on June 5 (2026-06-05), during commissioning ahead of commercial operations. The roughly month-long gap between first production and the July 8 (2026-07-08) cargo lift fell within normal commissioning sequencing. The subsequent inspection shutdown, disclosed in early August (2026-08-04), extended that pre-commercial period further.1,7
Sempra described the inspection as planned but provided no timeline for completing the checks or restarting operations, based on available reporting. That leaves the commercial operations declaration date open, and with it the start date for TotalEnergies' long-term offtake obligations.7
The cargo that shipped on July 9 (2026-07-09) went to Asia, completing ECA's first demonstration of the Mexico Pacific route. TotalEnergies noted the Baja California location enables export of US natural gas to Pacific Basin markets through shorter shipping distances than Gulf alternatives. One cargo is too small a sample to validate commercial economics at scale, but it confirmed the supply chain from US feed gas through liquefaction to Asian delivery can function.5,2
What Sempra discloses about the inspection findings, and when it restarts the plant, shapes how much of the 2026 shipping calendar ECA Phase 1 contributes to Pacific LNG supply. The commissioning extension does not alter the 20-year contract, but every month in pre-commercial status is a month TotalEnergies is not lifting its agreed volumes under that deal.7,2
