Epcilon LNG Seeks DOE Extension for Export Start Deadline

## Summary

Epcilon LNG LLC is asking the Department of Energy for more time to start exporting liquefied natural gas (LNG) from their planned terminal in Mexico. This extension delays their export deadline but keeps their permission to sell U.S. natural gas to certain countries. If approved, it gives Epcilon extra breathing room without changing any money terms—just the timeline.

## Abstract

The Office of Fossil Energy and Carbon Management (FECM) (formerly the Office of Fossil Energy (FE)) of the Department of Energy (DOE) gives notice (Notice) of receipt of a request (Request), filed on December 15, 2025, by Epcilon LNG LLC (Epcilon). Epcilon asks DOE to amend its existing authorization to re-export U.S.-sourced natural gas in the form of liquefied natural gas (LNG) from the proposed Amigo LNG export terminal project (Project), to be located in Guaymas, Sonora, Mexico, to non-free trade agreement countries set forth in DOE/FE Order No. 4629 (as amended)--specifically, to extend its current export commencement deadline. Epcilon filed the Request under the Natural Gas Act (NGA).
