Transwestern Pipeline Company, LLC—an operating subsidiary of Energy Transfer LP—announced today, September 26, 2025, that it is launching a binding open season for the Desert Southwest expansion project. The open season will run from 12:00 p.m. CDT on September 26 to 12:00 p.m. CDT on October 25, giving shippers the opportunity to bid for capacity to move Permian natural gas to markets in Arizona, New Mexico and Texas.
The expansion will extend ET’s existing Permian pipeline network into the growing Desert Southwest region, adding new miles of pipeline and compressor stations that will increase the partnership’s transport capacity and fee‑based revenue potential. By opening the season now, ET signals its commitment to accelerating the project’s construction schedule and to capturing the rising demand for natural gas in the Southwest, a key growth area for the company’s 2025 capital allocation plan.
For investors, the binding open season represents a tangible step toward expanding ET’s asset base and generating additional fee income. The move also supports the partnership’s broader strategy of leveraging its integrated system to secure long‑term contracts with minimal capital outlay, thereby improving cash flow stability and supporting future dividend and share‑holder return initiatives.
