Glenfarne Group announced it has completed a series of major advances that move Phase One of the Alaska LNG Project from the development phase into execution. Phase One comprises a 739-mile, 42-in. pipeline constructed in four simultaneous sections designed to deliver natural gas from Alaska’s North Slope. Phase One may also include the 63-mile, 32-in. Point Thomson Lateral Pipeline, according to Glenfarne.
The company is anticipating the delivery of first gas in 2029.
Advances in Phase One include:
- Worley Ltd. has been tapped to provide engineering, procurement, and construction management services for Phase One. This announcement follows the company’s completion of engineering work at the end of 2025 sufficient for a final investment decision.
- Glenfarne announced conditional awards for pipeline construction and line-pipe supply following a multiround bid process that originally included 20 participants. MasTec Inc., Quanta Services Inc., and joint ventures between Michels Pipeline Inc. and Houston Contracting Company, Associated Pipe Line Inc. and Cruz Construction, Barnard Pipeline Inc. and SICIM SpA, and Spiecapag and US Pipeline were among companies to receive awards that includes pricing, technical specifications, and roles within the construction strategy for Phase One.
“These world-class pipeline construction partners were selected based on their qualifications and experience to build the Alaska LNG pipeline, one of the most important pieces of energy infrastructure in the world. Each has dedicated a significant amount of time and resources in estimating and bidding for these roles, and their early involvement is foundational for this pipeline,” said Glenfarne CEO and founder Brendan Duval.
- To complete Phase One, 700,000 metric tonnes of API 5L X70 line pipe and 25,000 metric tonnes of line pipe for the Point Thomson Lateral are needed. Glenfarne announced it has made preliminary agreements for approximately two thirds of the needed line pipe to Corinth Pipeworks SA and Europipe GmbH.
- Glenfarne has also executed a gas sales precedent agreement (GSPA) with ExxonMobil, ConocoPhillips, and Hilcorp Alaska LLC for gas supply to the pipeline. This announcement comes after Glenfarne previously signed a GSPA with Pantheon Resources. ConocoPhillips and ExxonMobil have participated in various activities to advance Alaska LNG since 2014.
- The company said it also advanced agreements with major in-state customers to anchor demand and support North Slope gas utilization. Glenfarne signed a signed a nonbinding letter of intent with ENSTAR Natural Gas Company for a 30‑year supply of natural gas from the Alaska LNG pipeline to ENSTAR. A letter of intent was also signed with Donlin Gold Mine for the delivery of up to 50 MMcf/D of natural gas, along with collaboration on the development and construction of a 315-mile natural-gas pipeline and a power plant to supply the mine.
“This is about progressing from planning to building. By aligning construction, pipe supply, gas supply, and in-state customers, we are advancing Alaska LNG in a concrete way that is practical, financeable, and focused on delivering real benefits to Alaskans,” said Duval.
Alaska LNG is being developed by 8 Star Alaska LLC, which is owned 75% by Glenfarne and 25% by the State of Alaska through the Alaska Gasline Development Corp.
