Project Overview

The Alaska LNG project is a natural gas project located in the United States. Developed by a joint venture between Glenfarne & the Alaska Gasline Development Corporation (AGDC), the project will deliver natural gas from the North Slope gas fields for in-state distribution and for international markets. For this purpose, it will use clean, energy-efficient, and safe production methods. 

Alaska's people will gain a long-term and affordable source of natural gas for home heating, power generation, and industrial needs. 

The Prudhoe Bay and Point Thomson fields form the core of the North Slope project. It will produce approximately 3.5 billion cubic feet of gas per day. The Prudhoe Bay field will make up to 75% of the gas, as compared to the Point Thomson fields. 

It comprises the following: 

• An approximately 807-mile, 42-inch diameter gas pipeline.
  

• A Gas Treatment Plant (GTP) within the Prudhoe Bay Unit (PBU) on the North Slope
  

• A Gas Transmission Line of approximately 1 mile, 60-inch diameter, connecting the GTP to the PBU gas production facility.
  

• An approximately 63-mile, 32-inch diameter gas transmission line connecting the GTP to the Point Thomson gas production facility.
  

Alaska LNG Project Capacity

The Alaska LNG Project is designed to produce up to 20 million metric tons per annum (MTPA) of LNG. The North Slope gas fields are expected to produce up to 3.5 billion cubic feet of gas per day & deliver to the International Markets. 

Alaska LNG Project Location

The Alaska LNG Project is located in Alaska, United States. It comprises a pipeline and export facility system, spanning from northern oil and gas fields to tidewater on the southern coast of the state. 

It starts at Prudhoe Bay on Alaska’s North Slope, generating gas from both the Prudhoe Bay and Point Thomson fields in the Arctic region.

It ends at  Nikiski on the Kenai Peninsula, southcentral Alaska, where the liquefaction facility and export terminal are located.

Project Background

The Alaska LNG Project is one of North America’s largest natural gas infrastructure projects, built to commercialize Alaska’s extensive North Slope gas reserves. Since its conception in early 2010, the project has gone through several pivotal stages, market shifts, and leadership changes in response to evolving energy sector trends.

It began as a partnership between ExxonMobil, BP Alaska, ConocoPhillips, and the state-owned Alaska Gasline Development Corporation (AGDC), aiming to produce, transport, and export North Slope gas to global markets during a period of growing Asian LNG demand (2013–2014). 

Later in 2016, AGDC became a sole developer, as the other private oil companies withdrew their names from the project, due to an LNG surplus that had depressed gas prices. On April 17, 2017, the AGDC submitted its application to the Federal Energy Regulatory Commission (FERC) to approve the project by December 2018, ensuring it can be operational by 2024. 

In March 2020, the FERC published the final Environmental Impact Statement (EIS) for the project, which analyzed the project’s environmental impacts and necessary mitigation measures. In May 2020, FERC authorized the Alaska LNG project. 

In March 2025, Glenfarne took a 75% stake in the project and became its lead developer. AGDC now only has a 25% stake in the project. Taiwan’s CPC signed a non-binding letter of intent with Alaska Gasline Development Corporation, indicating its plan to invest in and purchase LNG from the project. 

Alaska LNG Project Completion Date

The Alaska LNG project expects to make a Final Investment Decision (FID) for its pipeline by late 2025 and to begin construction by late 2026. The project is expected to complete its full operation by Mid-2029.

Alaska LNG Project Cost

The total estimated cost for the Alaska LNG project is approximately USD 44 billion. It includes the overall cost till the completion of the project, including the price of the pipeline, gas treatment plant, and Nikiski LNG export terminal.

The Two Phases of the Alaska LNG Project

The Alaska LNG project is to be built in two phases.

• Phase I of the project will focus on the domestic pipeline to rapidly deliver North Slope gas to Alaskans and manage overall project risk. It will provide natural gas up to approximately 765 miles from the North Slope to the Anchorage region.
  

• Phase II focuses on the LNG export terminal and associated infrastructure. It includes the Alaska LNG facility, approximately 42 miles of pipeline under Cook Inlet, and pipeline compression equipment. 

Project Scope

The project scope includes the following: 

• Pipeline Development: The project involves the construction of an 807-mile, 42-inch diameter pipeline from the North Slope gas field to Southcentral Alaska.
  

• Liquefaction and Export Facilities: Approximately 20 million metric tons per annum (MTPA) of LNG will be exported from Nikiski to global markets, primarily Asia, for liquefaction and export.
  

• Gas Production: The project utilizes gas from the Prudhoe Bay and Point Thomson fields, of about 3.5 billion cubic feet per day, mainly from Prudhoe Bay (75%) and Point Thomson (25%), to feed the pipeline and LNG facilities.
  

• Supported Infrastructure: In-state facilities include gas metering, compressor stations, and potentially additional expansion segments to meet regional demand.

Alaska LNG Project Latest Updates

The Alaska LNG project has signed new agreements for the LNG Supply. These are as follows:

Alaska LNG and JERA Signed a Letter of Intent for LNG Supply Agreement

On September 10, 2025, the Alaska LNG (majorly owned by Glenfarne) and JERA Co., Inc. (JERA), Japan’s largest power generation company, signed a Letter of Intent (LOI) to supply one million tonnes per annum (MTPA) LNG for over 20 years on a Free-on-Board basis. 

The 20-MTPA Alaska LNG project, the only federally authorized LNG export project on the U.S. Pacific Coast, is a joint venture between Glenfarne and the Alaska Gasline Development Corporation. 

This agreement between Alaska LNG and JERA positions Alaska as a long-term LNG supplier for Japan, contributing to Japan’s energy security and decarbonization strategy. Due to its proximity and integrated infrastructure model, it will supply LNG at lower shipping and liquefaction costs than Gulf Coast projects. 

Upon the operation, the Alaska LNG project will be the lowest-carbon LNG project in the world. A study conducted under the Department of Energy National Energy Technology Laboratory's methodology highlights Alaska LNG’s global commitment to reducing CO2 emissions by up to 77 million tonnes per year. This is achieved by offsetting the growing coal use in Asia and reducing shipping emissions, thanks to Alaska’s proximity to Asia.
