Enterprise completes 8 new NGL pipelines
EIA reports eight liquid-fuel pipeline projects finished in 2025-2026, plus 14 new announcements, detailing capacity and mileage for key lines.
The U.S. Energy Information Administration (EIA) announced that eight liquid-fuel pipeline projects were completed between January 2025 and June 2026, and 14 new projects have been announced. The completed projects include the Bahia Pipeline, Coastal Bend NGL Pipeline Expansion 1, Hiland Express Project, MPLX-BANGL Expansion 1, Santa Fe Pacific East Line Expansion 1, Santa Ynez Pipeline System, Seahawk pipeline-Thunderdome Lateral, and Seminole Red Pipeline (Midland-to-Echo 2). The new projects are Bahia Pipeline Expansion, Bayou Bridge Pipeline Expansion, Bridger Pipeline Expansion, Coastal Bend NGL Pipeline Expansion 2, Enbridge Mainline Optimization Phase 1 and 2, Flanagan South Pipeline Expansion, Puget Sound Pipeline Optimization, Santa Fe Pacific Pipeline East Line Expansion 2, Southern Illinois Connector, Sun Belt Connector, Western Gateway Pipeline, Western Markets Pipeline Expansion Phase 1 and 2.
Completed Projects
The following table lists the projects with reported mileage and capacity:
| Project | Mileage | Capacity (b/d) |
|---|---|---|
| Bahia Pipeline | 550 miles | 600,000 |
| Coastal Bend NGL Pipeline Expansion 1 | - | 225,000 |
| MPLX-BANGL Expansion 1 | - | 250,000 |
The Bahia Pipeline originates in West Texas from the Delaware and Midland basins and connects to Enterprise’s fractionation complex in Chambers County, Texas. The Coastal Bend NGL Pipeline Expansion 1, formerly the EPIC Y-grade pipeline, added 50,000 b/d to reach a total of 225,000 b/d, carrying Y-grade from West Texas to Corpus Christi. Hiland Express Project saw Kinder Morgan convert the Double H Pipeline system from crude oil to NGL. MPLX-BANGL Expansion 1 increased total capacity to 250,000 b/d, moving Y-grade from the Delaware and Midland basins to a fractionator in Sweeny, Texas. Santa Fe Pacific East Line Expansion 1 extended a line from El Paso, Texas, to Tucson, Arizona, to transport gasoline, diesel, and jet fuel.
The Santa Ynez Pipeline System, formerly the California 901R & 903R restart, was revived by Sable Offshore Corporation (Pacific Pipeline Company). Seahawk pipeline-Thunderdome Lateral, Gray Oak Louise converted a 16-inch natural gas line to crude oil, running from the Gray Oak Louise terminal to the Edna terminal and ultimately to the Seahawk terminal in Texas. Seminole Red Pipeline (Midland-to-Echo 2) was converted back to an NGL line while the Bahia pipeline was built.
New Announcements
The 14 newly announced projects span a range of regions and purposes. They include expansions of existing lines, such as the Bahia Pipeline Expansion and Coastal Bend NGL Pipeline Expansion 2, as well as new corridors like the Bayou Bridge Pipeline Expansion and the Southern Illinois Connector. Optimization phases for Enbridge Mainline and the Western Markets Pipeline are also in the pipeline. These announcements were sourced from pipeline company websites, trade press reports, and government documents, as noted by the EIA.
Database Overview
The EIA’s Liquids Pipeline Projects Database tracks more than 280 future, ongoing, and past liquid-fuel pipeline projects in the United States. It records project types, start dates, capacity, mileage, geographic information, and status. The database is updated based on publicly available information and does not reflect any mandatory survey data. For more detailed statistics, see the EIA’s stats page.
Project Connections
Some projects are interconnected, with segments doubling as parts of longer lines that may transport the same fuels to final destinations. Because of these overlaps, summing the capacities of all projects could overestimate or double-count total pipeline capacity. The database therefore tracks expanded, reversed, converted, and new pipeline projects separately to avoid such miscounts.
The Liquids Pipeline Projects Database complements the EIA’s Natural Gas Pipeline Projects tracker. The database includes projects dating back to 2010 and is maintained by EIA staff. For additional context on pipeline infrastructure, refer to the EIA’s fixtures and squad pages. The latest update was released on August 26, 2026.
