Glenfarne Alaska LNG targets late-2026 construction start for 807-mile pipeline project

Glenfarne Alaska LNG says it expects to begin construction on its planned 807-mile natural gas pipeline in late 2026, with operations targeted for mid-2029. According to Alaska's News Source, the company outlined the timeline following a recent meeting between Glenfarne Alaska LNG President Adam Prestidge and Japanese Consul Kiyohiko Hamada in Anchorage, signaling ongoing international interest in the project’s progress. 

The proposed pipeline, part of the broader Alaska LNG export initiative, would follow much of the Trans-Alaska Pipeline corridor and transport an estimated 3.5 Bcfg/d from Alaska’s North Slope to the Kenai Peninsula for liquefaction and export. The project aims to strengthen long-term energy cooperation between Alaska and Japan while expanding U.S. LNG export capacity to Pacific markets.

According to the company, the construction schedule aligns with earlier projections from U.S. Interior Secretary Doug Burgum, who has said the Alaska LNG pipeline could begin construction in 2026, Alaska's News Source reported. However, federal permitting records show three key approvals remain pending.

The pipeline’s advancement comes amid tightening state budgets and shifting energy economics. Alaska Governor Mike Dunleavy recently cited falling oil prices and reduced revenue as major fiscal challenges, while lawmakers continue to highlight LNG infrastructure as a potential driver of future growth.

Support for the project has come from both state and federal levels. Earlier this year, President Donald Trump signed an executive order prioritizing development of Alaska’s LNG export capacity, describing it as vital for energy security and global market stability.

Despite optimism, the project still faces regulatory, financial, and environmental hurdles. Previous LNG pipeline proposals in Alaska have been delayed or canceled over similar challenges. Glenfarne has not yet disclosed updated cost estimates or financing details for the project.

If realized, the Alaska LNG pipeline would represent one of the largest U.S. energy infrastructure projects currently planned, supporting domestic gas transport, international trade, and regional economic development.
