WhiteWater, Devon Energy, MPLX LP, Diamondback Energy and Western Midstream Partners reached a positive final investment decision, the point at which a project's partners commit capital to build it, to construct two 48-inch natural gas pipelines from the Permian Basin to Katy, Texas, about 30 miles west of downtown Houston. The project moves forward through the group's Solitude Pipeline System joint venture, backed by long-term firm transportation agreements with predominantly investment-grade shippers.
Capacity and timeline
Solitude's design phases in capacity instead of opening at full volume. The system provides about 2.25 Bcf/d of initial capacity in late 2029, then adds another 2.25 Bcf/d in 2030, for a combined 4.5 Bcf/d once both phases are running. Capacity can grow further after that to meet shipper demand, and each phase's commissioning date can move earlier or later to match market conditions. Solitude is expected to enter service in the second half of 2029, subject to regulatory and other approvals.

What it moves
The two pipelines are built to move gas produced in the Permian to the Gulf Coast, where WhiteWater and its partners point to both rising Permian Basin output and expanding Gulf Coast consumption as what the added capacity supports.
