Glenfarne Moves Alaska LNG Phase One Into Early Execution
Glenfarne says Phase One of the Alaska LNG project is moving into early execution, with pipeline construction awards, line pipe supply agreements, and gas sales deals advancing a 739-mile natural gas pipeline aimed at serving Alaska’s domestic market.
(P&GJ) — Glenfarne Group says Phase One of its Alaska LNG project has entered early execution, with conditional awards issued for pipeline construction, line pipe supply agreements secured, and multiple gas sales agreements signed to support in-state demand.
Phase One centers on a 739-mile, 42-inch natural gas pipeline designed to move gas from Alaska’s North Slope to domestic markets. Glenfarne is targeting mechanical completion in 2028 and first gas in 2029. A potential 63-mile, 32-inch Point Thomson lateral may also be included.
“This is about progressing from planning to building,” said Glenfarne Chief Executive Officer Brendan Duval. “By aligning construction, pipe supply, gas supply, and in-state customers, we are advancing Alaska LNG in a concrete way that is practical and financeable.”
Glenfarne provisionally selected Worley to provide engineering, procurement and construction management services for Phase One, following completion of front-end engineering work in late 2025. The award remains subject to a definitive agreement.
The company also issued conditional construction awards across multiple pipeline spreads following a competitive bid process, naming contractors including subsidiaries of MasTec and Quanta Services, along with several joint ventures involving Alaska-based firms. Awards remain subject to final construction agreements.
To support construction, Glenfarne executed preliminary agreements covering roughly two-thirds of the required API 5L X70 line pipe, with suppliers including Corinth Pipeworks and Europipe. Pipeline manufacturing is expected to begin shortly, with deliveries into Alaska later this year.
On the supply side, Glenfarne signed gas sales precedent agreements with North Slope producers, including ExxonMobil and Hilcorp Alaska, building on previously announced agreements with Pantheon Resources. ConocoPhillips also reaffirmed its support for advancing the project.
In parallel, Glenfarne advanced in-state demand agreements, including a non-binding letter of intent with ENSTAR Natural Gas for a proposed 30-year gas supply arrangement, subject to regulatory approval. Additional agreements include a letter of intent to supply gas to the Donlin Gold Mine, which could involve construction of a separate pipeline and power facility.
Phase Two of Alaska LNG would add liquefaction facilities to export up to 20 million metric tons per year of LNG. Glenfarne became lead developer of the project in March 2025 and holds a 75% ownership stake, with the State of Alaska, through the Alaska Gasline Development Corporation, owning the remaining 25%.
