Background

The EIA notes this would be a new pipeline to deliver gas from the Haynesville basin to U.S. Gulf Coast markets, including LNG. The system would ultimately be expandable to 2200 MMcf/d.

In 2024, Energy Transfer "filed a lawsuit to block the [NG3] project from crossing its Gulf Run Pipeline." Energy Transfer also filed legal action against two other rivals, DT Midstream and Williams for their Louisiana Energy Access Project (LEAP) and Louisiana Energy Gateway Project (LEG), respectively. DT Midstream lost its court case in April and completed an alternative route to avoid further delays, while Williams was granted permission to continue with the LEG project in the second half of 2024.

In August 2024, construction of the NG3 project was back on track, after the "parties eventually settled the matter, and Louisiana's 42nd District Court granted a motion "dismissing all claims asserted by all parties" on June 10, clearing the way for construction to continue." The project is expected to begin operations in the fourth quarter of 2025.
