US Natural Gas Pipeline Capacity Expansion in 2025 Focused on Haynesville Shale for LNG Exports
In 2025, US natural gas pipeline projects will increase capacity by approximately 6.3 Bcf/d, with 85% directed to LNG export terminals on the Gulf Coast. Most new pipelines will connect the South and Central US, primarily serving the growing gas demand in the region. Notably, intrastate pipelines will account for 65% of the new capacity. Major projects include the Louisiana Energy Gateway and New Generation Gas Gathering systems, which together add 3.5 Bcf/d. Haynesville shale is predicted to drive two-thirds of the gas production increase over the next two years.

In 2025, the United States will see a 6.3 Bcf/d increase in natural gas pipeline capacity, with 5.3 Bcf/d (85%) aimed at LNG export terminals on the Gulf Coast. Most of the new pipelines will connect the South and Central regions.
Intrastate pipelines will represent 65% of the new capacity, continuing the trend of greater intrastate than interstate expansion. Significant projects include the Louisiana Energy Gateway and New Generation Gas Gathering systems, which together contribute 3.5 Bcf/d. The Haynesville shale region is expected to account for two-thirds of the increase in domestic gas production, projected to rise to 122.3 Bcf/d by 2027, driven by demand for LNG exports and fuels for data centers.
