DOE receives Rio Grande LNG Train 6 application to export 312 Bcf per year to non-FTA nations

Executive Summary

Rio Grande LNG Train 6, LLC filed an application on June 11, 2026 seeking long-term authorization to export approximately 312.05 billion cubic feet of LNG per year. The Department of Energy's Hydrocarbons and Geothermal Energy Office published notice of the application on June 26, 2026. The proposed export would originate from an expansion of the existing Rio Grande LNG Terminal along the Brownsville Ship Channel in Cameron County, Texas.

Bottom Line

The notice opens a formal DOE proceeding for 312.05 Bcf per year of non-FTA LNG export capacity tied to an expansion of an already-authorized Texas terminal. The application sits inside the restored standard review process following the January 2025 executive directive ending the prior export-authorization pause. Offtake counterparties, competing export applicants, and domestic gas consumers each hold standing to intervene in the proceeding, and the outcome carries direct implications for long-term LNG supply contracting across non-FTA markets.

Key Regulatory Signals

Non-FTA Export Authorization Sought: The application targets non-Free Trade Agreement nations, the category requiring affirmative DOE authorization under the Natural Gas Act. Approval would open export volumes to a broad set of counterparties, including European and Asian buyers, that fall outside the automatic-approval pathway available for FTA-nation destinations.
Expansion Layered onto Existing Permitted Terminal: The proposed Train 6 project is sited at and adjacent to the previously authorized Rio Grande LNG Terminal. This co-location positions the application to leverage existing environmental and siting reviews, though a separate Federal Energy Regulatory Commission authorization for the expansion facilities remains a prerequisite to export authorization taking effect.
Volume Scale Places This Among Larger Pending Applications: At 312.05 Bcf per year, the requested export volume is substantial relative to the current U.S. LNG export capacity base of roughly 14 billion cubic feet per day. Counterparties negotiating long-term offtake agreements with RGLNG Train 6 now have a formal DOE proceeding on record against which to structure conditional commitments.
Public Comment Period Now Open: DOE's notice of receipt initiates the formal review process under the Natural Gas Act, which includes a public comment period. Competing exporters, domestic gas consumers, environmental intervenors, and foreign-policy stakeholders may file protests or motions to intervene, each of which can extend the review timeline.

Regulatory Delta

- DOE has operated under a January 2025 executive directive that lifted the prior administration's pause on non-FTA LNG export authorizations, restoring the standard review process this application now enters.

- Train 6 is an incremental expansion, not a greenfield project. That distinction may compress the environmental review timeline relative to entirely new terminal applications.

- FERC retains independent jurisdiction over the physical facilities, and DOE authorization and FERC approval proceed in parallel rather than in sequence. Commercial timelines therefore depend on both agencies completing their respective reviews.

Intelligence Outlook

Monitor the DOE Hydrocarbons and Geothermal Energy Office docket for this proceeding for the comment-period close date, any protests or motions to intervene, and the issuance of a final order or conditional authorization.
