Sempra Extends ECA LNG Commissioning After Post-Cargo Inspection Shutdown
Mexico's first Pacific Coast LNG export terminal faces a delayed commercial startup after Sempra halted operations for inspections, with no new timeline disclosed.
Sempra Infrastructure said on August 4 (2026-08-04) it had extended the commissioning process for the ECA LNG Phase 1 terminal in Ensenada, Mexico, after the plant was shut down for planned inspections following the export of its first cargo. The company gave no revised target date for the start of commercial operations.6
The extension reversed what had appeared to be steady progress. ECA shipped its inaugural LNG cargo to Asia on July 8 (2026-07-08), with TotalEnergies lifting the cargo as the project's sole offtaker during the ramp-up phase. The French energy major said it was "pleased to contribute to the project's ramp-up by exporting its first LNG cargoes."4,3,5
ECA LNG Phase 1 is Mexico's first LNG export terminal on the Pacific Coast, and currently the region's only operational liquefaction facility. Built in Baja California, the plant is positioned to route US natural gas to Asian and Pacific Basin buyers on a shorter sea voyage than cargoes departing from Gulf Coast terminals.5,3
The terminal has a single liquefaction train with a nameplate production capacity of 3.25 million tonnes per annum (Mtpa). TotalEnergies, which holds a 16.6% equity stake alongside operator Sempra Infrastructure, a subsidiary of Sempra (NYSE: SRE), has a 20-year sales agreement to purchase 1.7 Mtpa from the project once commercial operations begin, a volume representing just over half of the train's rated output.1,2,4
The ramp-up arrangement and the long-term contract are distinct. During commissioning, TotalEnergies acts as the sole buyer of whatever LNG the plant produces. The 20-year, 1.7 Mtpa agreement activates only when Sempra formally declares commercial operations, a milestone the August 4 (2026-08-04) announcement has pushed further out without specifying when it will arrive.3,2,6
First LNG production at ECA was achieved in early June 2026 (2026-06-05) as part of the commissioning sequence, with the inaugural cargo exported a little over a month later. That pace suggested the facility was advancing through startup efficiently. The post-cargo shutdown and commissioning extension have altered that impression.1,6
Sempra described the shutdown as tied to planned inspections, framing the halt as a scheduled step rather than a fault response. But the decision to extend the commissioning timeline without setting a replacement date for commercial startup points to work that requires more time than a brief check-and-restart.6
The Pacific Coast location underpins ECA's commercial rationale. Mexico's Pacific seaboard reduces the shipping distance to key Asian LNG import markets compared to the US Gulf Coast, and TotalEnergies has pointed to those shorter routes as central to the terminal's ability to serve Pacific Basin demand. Asian LNG benchmark JKM was priced at $21.41/MMBtu on August 15 (2026-08-15).5,3
NYMEX Henry Hub front-month gas closed at $2.75/MMBtu on August 15 (2026-08-15). The spread between that feedstock level and JKM prices supports the broad economics of Pacific Basin LNG exports. Those economics only materialize when the liquefaction plant runs, and Sempra has not said when it expects that to happen sustainably.5
Sempra has given no new target for commercial startup. For now, ECA Phase 1 remains in an indefinite commissioning extension, with its first Pacific Coast LNG tonnes yet to count toward the 1.7 Mtpa TotalEnergies is contracted to offtake annually for 20 years.1,2,6
