ouble E Pipeline is a Summit Midstream–ExxonMobil joint venture advancing a major compression expansion to move additional Delaware Basin natural gas to the Waha Hub. Its September 23, 2026, air permit registration for a mainline compressor station near Mentone provides a specific facility-development signal, although the supplied TCEQ record still shows the application as pending.
Summit Midstream has approved a roughly $100 million expansion of the 135-mile Double E Pipeline, adding compression that could increase Delaware Basin gas transportation capacity toward Waha by approximately 900 MMcf/d. The project has secured 550 MMcf/d of new long-term commitments, bringing contracted firm capacity to about 2.2 Bcf/d, with startup targeted for Q4 2028.
Double E is a 135-mile Federal Energy Regulatory Commission-regulated interstate natural gas transmission pipeline that commenced operations in November 2021 and provides transportation service from receipt points in the Delaware Basin to various delivery points in and around the Waha hub in Texas.
