A Summit Midstream Partners LP subsidiary has launched an open season through Sept. 14 to test support for the Double E Pipeline, which would transport Permian Basin natural gas from the Delaware sub-basin to markets south on the U.S. Gulf Coast and into Mexico.

The binding open season by Summit Permian Transmission LLC is gauging interest in Double E to service various receipt points in New Mexico’s Eddy and Lea counties and the West Texas counties of Loving, Ward, Reeves and Pecos.

From the Waha Hub in West Texas the system could connect with “multiple current and planned takeaway pipelines” to demand centers south, Summit noted.

The target in-service date is 2Q2021, subject to regulatory approvals.

Summit said it already has a long-term binding commitment with an undisclosed foundation shipper for up to 500,000 Dth/d of firm transportation capacity.

Earlier on Monday, four operators led by Houston’s Targa Resources Corp. rolled out plans to develop the 2 Bcf/d Whistler Pipeline Project to carry gas to Gulf Coast markets and beyond. Targa said a letter of intent is in place for the joint venture project with MPLX LP and NextEra Energy Pipeline Holdings LLC, a subsidiary of NextEra Energy Resources LLC, as well as WhiteWater Midstream LLC,which is a portfolio company of Denham Capital Management and Ridgemont Energy Partners.

Kinder Morgan Inc. is now building the 2 Bcf/d Gulf Coast Express pipeline project from the Permian to the Gulf Coast, which is scheduled for in-service in late 2019. Kinder and its partners also have the Permian Highway Pipeline on the drawing board, which if sanctioned could ramp up in late 2020,
