Energy Transfer

Transwestern Pipeline, a subsidiary of Energy Transfer LP, announced an open season (Sept 26-Oct 25, 2025) for an expansion of its natural gas pipeline across TX, NM, and AZ. The Desert Southwest expansion aims to transport at least 1.5 Bcf/d of Permian Basin natural gas to markets in the Southwest, anticipating increased demand. Sufficient commitments exist, but additional commitments will optimize the project, targeting Q4 2029 operation, pending regulatory approvals. The expansion addresses Permian takeaway capacity constraints but faces environmental and economic challenges.
