WES holds a 7.5% equity interest in the Solitude Pipeline System joint venture which has reached a positive Final Investment Decision to construct two 48-inch natural gas pipelines running from the Permian Basin to Katy, Texas.
Solitude will deliver scalable, long-haul natural gas transportation, with initial capacity of approximately 2.25 Bcf/d expected in late 2029 and an additional 2.25 Bcf/d in 2030 with the ability to increase capacity thereafter to accommodate shipper demand.
WES has taken firm transportation capacity on the pipelines, providing incremental residue takeaway and enhanced flow assurance for its Delaware Basin customers.
HOUSTON, Aug. 17, 2026 /PRNewswire/ -- Today, Western Midstream Partners, LP (NYSE: WES) ("WES" or the "Partnership"), announced its participation in the Solitude Pipeline System joint venture ("Solitude"), operated by WhiteWater. Through Solitude, in which WES holds a 7.5% equity interest, a positive Final Investment Decision ("FID") has been reached to construct two 48-inch natural gas pipelines, each running from the Permian Basin to Katy, Texas. The project has secured substantial long-term firm transportation agreements with predominantly investment-grade shippers to support the FID. Solitude will deliver scalable, long-haul natural gas transportation to support Permian Basin growth and expanding Gulf Coast markets.
The joint venture's pipeline system will feature a flexible, phased design that provides initial capacity of approximately 2.25 Bcf/d in late 2029, and an additional 2.25 Bcf/d in 2030, with the ability to increase capacity thereafter to accommodate shipper demand. Capacity commissioning can be accelerated or deferred to align with evolving market dynamics. Solitude is expected to enter service in the second half of 2029, subject to receipt of customary regulatory and other approvals.
"We are excited to partner with WhiteWater and the other owners of Solitude to build incremental natural-gas takeaway that supports continued Permian Basin growth and expanding Gulf Coast demand, including LNG exports," said Oscar K. Brown, President and Chief Executive Officer of WES. "Unlike our other long-haul joint ventures, WES has taken firm capacity on the Solitude pipelines, enabling enhanced flow assurance for our customers. We firmly believe that as the basin continues to be developed and gas-to-oil ratios rise, residue takeaway capacity will be critical to allow Permian Basin producers to maximize the value of their production, and this investment allows us to better serve current customers and compete for new volumes, all while meeting our required return thresholds."
