EIA reports on new natural gas pipelines in the US

Published by , Editor
World Pipelines,

The US is expected to add between 16 billion ft3/d and 17 billion ft3/d of natural gas pipeline capacity in 2019, most of which was built to provide additional takeaway capacity out of supply basins. Of the 134 active natural gas pipeline projects the US Energy Information Administration (EIA) tracks, 46 have entered or are expected to enter service in 2019. These projects will increase deliveries by pipeline to Mexico or to liquefied natural gas (LNG) export facilities in the Gulf Coast region.

More than 40% of this new pipeline capacity – 7.2 billion ft3/d – delivers natural gas to locations within the South Central region. Many of these pipeline projects will provide additional takeaway capacity out of the Permian Basin in western Texas or enable additional Permian natural gas production to reach the interstate pipeline system. Some of these pipelines include:

Kinder Morgan’s 2 billion ft3/d Gulf Coast Express Pipeline, which provides takeaway capacity from the Waha Hub in the Permian Basin (near the Texas-New Mexico border) to demand markets on the Gulf Coast at the Agua Dulce Hub.

ONEOK'S Roadrunner Eastbound Expansion, which added about 1 approximately billion ft3/d of bidirectional capacity on the pipeline, and the 300 million ft3/d WesTex Expansion, which added northbound takeaway capacity out of the Permian Basin.

El Paso Natural Gas Pipeline’s 320 million ft3/d Northern Delaware Basin Expansion Project, which is still under construction and will add additional capacity to the El Paso system in western Texas, allowing additional volumes to flow westward on the system.

The remainder of the natural gas pipeline projects slated for completion in the South Central region in 2019 will deliver natural gas to demand centres, in particular to LNG export facilities on the Gulf Coast. Cheniere’s 1.4 billion ft3/d MIDSHIP Pipeline is still under construction. When completed, it will connect natural gas supply from Oklahoma to the Sabine Pass LNG facility in Louisiana, providing additional sources of secure supply to the export terminal.

The Texas East Transmission Company (TETCO) completed expansions to its existing pipeline infrastructure during the 2Q19, including the 400 million ft3/d Stratton Ridge Expansion, for additional deliveries to the Freeport LNG facility on the Texas Gulf Coast.

The only pipeline project in the South Central region in 2019 that moves natural gas outside its region is the 2.6 billion ft3/d Valley Crossing Pipeline, which exports to markets in Mexico. This pipeline connects to the newly built Sur de Texas-Tuxpan pipeline, a 497 mile underwater project that was also completed in 2019 and transports US natural gas to the southern Mexican state of Veracruz.

After the South Central region, the Northeast region built the most additional natural gas pipeline capacity in 2019, providing additional outlets for natural gas produced in the Appalachian Basin. Most of this new pipeline capacity is the result of projects that were originally slated to enter service in 2018.

The largest projects in the Northeast already completed in 2019 are Millennium Pipeline’s 223 million ft3/d Eastern System Upgrade Project, which increased deliverability to customers in Pennsylvania and New York, and Transcontinental Gas Pipeline Company’s 190 million ft3/d Rivervale South to Market Project, which increased deliverability into the New York City market.

The remainder of the new pipeline capacity in the Northeast connects natural gas supply to the NEXUS pipeline in the Midwest (the completed Appalachia Lease Project Phase 2) or to market hubs within the Northeast.

Additional information on these and other natural gas pipeline projects is available in EIA’s Natural Gas Pipeline Project Tracker, which is updated quarterly.
