It is more than an LNG terminal: the plan includes gas connections, a treatment plant, a long-distance pipeline, and—if Phase Two proceeds—a liquefaction plant and marine terminal near Nikiski.
How would Alaska LNG work?
The project’s proposed supply chain starts with North Slope gas and runs south to the Kenai Peninsula. Gas would be gathered from production areas, treated, and sent through a mainline pipeline. Phase One is intended to supply Alaskans; Phase Two would add equipment to cool gas into liquefied natural gas (LNG) for shipment from the Nikiski area. These are proposed facilities and uses, not a description of an operating end-to-end system.
- Gather North Slope gas. Proposed connecting lines would bring gas from Prudhoe Bay and Point Thomson to the gas treatment plant.
- Treat the gas. The plant would prepare the incoming gas for transmission through the mainline.
- Move it south. The mainline would carry treated gas toward Cook Inlet and the Kenai Peninsula, with compressor stations and a heater station along the route.
- Deliver it in Alaska, then potentially export it. The sponsor describes in-state delivery as the first phase. The later phase would add a liquefaction plant and marine terminal near Nikiski, where LNG could be loaded onto ships.
The sponsor’s project overview describes the two-phase concept. FERC’s final environmental impact statement (EIS), issued March 6, 2020, details the facilities it reviewed.
What is included in the proposed design?
The FERC-reviewed design combines a treatment plant, connecting pipelines, and a long-distance mainline with supporting facilities. The figures below describe proposed design capacities and facilities, not actual gas deliveries or LNG production.
#1 Best Overall
| Design element | Figure or description | Basis |
|---|---|---|
| Mainline pipeline | Approximately 806.9 miles long and 42 inches in diameter | FERC’s 2020 EIS |
| Gas treatment plant | One plant; proposed average inlet design capacity up to 3.7 billion standard cubic feet per day and peak capacity up to 3.9 billion standard cubic feet per day | FERC’s 2020 EIS |
| North Slope connections | One approximately 1-mile connection at Prudhoe Bay and one approximately 62.5-mile connection at Point Thomson | FERC’s 2020 EIS |
| Pipeline support | Eight compressor stations and one heater station | FERC’s 2020 EIS |
| LNG facility | Proposed capacity of up to 20 million metric tons of LNG per year | Alaska Gasline Development Corporation’s proposed facility design, as described by FERC in 2020 |
FERC describes the route as generally following the Trans-Alaska Pipeline System and highways south before continuing toward Cook Inlet and the Kenai Peninsula. The pipeline’s route and terminal location are part of the reviewed proposal; the figures do not establish that those facilities have been built.
What is the difference between Phase One and Phase Two?
The two phases have different facilities and intended destinations. Phase One is the in-state supply portion. Phase Two adds the equipment needed to make LNG and ship it overseas.
| Phase One | Phase Two | |
|---|---|---|
| Core facilities | North Slope connections, gas treatment plant, mainline pipeline, and supporting stations | Liquefaction plant and marine terminal near Nikiski, in addition to the upstream and pipeline system |
| Intended destination | Alaska users | Overseas markets by ship |
| Evidence about commercial arrangements | DOE’s April 2026 semiannual report said the project had no long-term gas supply contracts at the time covered and noted an early-works implementation plan filing for Phase One. | DOE’s February 2026 notice described an export-authorization request; that request is not evidence that LNG exports have begun or that sales are contracted. |
The phase descriptions and the status statements are time-specific. The DOE report does not establish the project’s contract or implementation status after the period it covers.
What do the export figures mean?
Two different kinds of figures appear in the project’s official records. FERC’s 2020 review describes the proposed LNG facility’s design capacity as up to 20 million metric tons per year. Separately, Alaska LNG Project LLC requested authorization from DOE to export up to 20 million metric tons annually for a 30-year term in a notice dated February 23, 2026. DOE gives a conversion factor of 46.467 billion cubic feet per million metric tons, which makes the requested annual volume about 929 billion cubic feet per year. The request is an application quantity, not a report of actual exports.
DOE’s notice also reproduces the applicant’s characterization of the project as unusually substantial in size, scope, costs, upstream development requirements, and schedule compared with LNG projects in the lower 48. That wording is the applicant’s position in a DOE docket notice, not an independent DOE finding. The notice and export docket are available from DOE.
What has been authorized, and what remains unresolved?
FERC authorized the Alaska LNG Project on May 21, 2020, according to its Alaska Gas Projects page. That milestone is part of a longer federal review history, not proof that every part of the project is fully permitted, financed, built, or operating. The federal Permitting Dashboard says DOE granted rehearing of a final order in 2021 and that the project was reopened to include DOE preparation of a supplemental environmental impact statement.

Agency responsibilities differ. FERC says it authorizes the siting and construction of onshore and near-shore LNG export or import facilities under Section 3 of the Natural Gas Act and conducts environmental reviews for proposed facilities within its jurisdiction. See FERC’s LNG jurisdiction overview. A FERC authorization, a DOE export application, an early-works filing, construction, and operation are distinct milestones.
DOE’s April 2026 report said there were no long-term LNG export or gas supply contracts at the time covered. The cited official material does not establish the project’s later contracting status. It also does not establish a verified current total project cost or a final investment decision date, so those figures cannot be stated as settled facts.

What did FERC’s environmental review conclude?
FERC’s 2020 EIS assessed expected impacts from construction and operation and described avoidance, minimization, and mitigation measures. Its summary said most impacts would either not be significant or could be reduced to less-than-significant levels with proposed or recommended measures, while also identifying some adverse and significant impacts. The conclusion is therefore qualified: the EIS did not say the project would have no significant impacts. It is an environmental review of the proposal, not evidence that construction has occurred or that every impact can be eliminated.
When would Alaska LNG exports begin?
The official records cited here do not establish a confirmed first-export date. The project remains described through proposed phases, regulatory actions, applications, and dated status reports; the DOE April 2026 report’s statements should not be treated as a current-status update beyond the period it covers. A proposed facility capacity or requested export volume cannot, by itself, show when construction, commercial operation, or shipments will begin.
