Williams continues to expect $7.3 billion to $7.9 billion of 2026 growth capital as it advances Transco, Clay Basin, Haynesville and power-infrastructure initiatives.

Allstream Insiders Summary
Williams has maintained its 2026 growth-capital outlook of $7.3 billion to $7.9 billion while reporting a series of midstream and power-infrastructure milestones. According to the company’s November 2 third-quarter announcement, the updates include the completed acquisition of Momentum Midstream, a proposed 9.4 Bcf expansion at Clay Basin storage, additional Transco capacity initiatives and the approaching in-service date for the Plato North Power project.
The company said it has expanded pipeline capacity by 413 MMcf/d across four projects, announced a proposed 150+ MMcf/d Transco Southeast Supply Enhancement II project, and increased Garden Connector capacity by 84 MMcf/d. Williams also said Socrates’ Plato North Power project was on track for service by mid-November.
The disclosure does not provide a project-by-project allocation of the company’s 2026 capital range. It also does not identify engineering, construction or equipment awards for the newly announced projects.
Williams’ project and capital update at a glance
| Item | Company-reported detail |
|---|---|
| 2026 growth-capital outlook | $7.3 billion–$7.9 billion |
| Momentum Midstream | Acquisition completed in September 2026; Williams’ results release says capital-investment figures exclude $2.816 billion for the transaction |
| Clay Basin | Proposed 9.4 Bcf storage expansion |
| Transco Southeast Supply Enhancement II | Announced capacity of more than 150 MMcf/d |
| Garden Connector | Capacity increased by 84 MMcf/d |
| Projects placed in service | 413 MMcf/d of combined pipeline-capacity expansion across four projects |
| Plato North Power | Targeted to enter service by mid-November, according to Williams |
Momentum acquisition strengthens Williams’ Haynesville position
Williams said it closed the Momentum Midstream acquisition during the quarter, expanding its position in the Haynesville basin. The company connected that position with growing LNG, industrial and power demand. Its third-quarter release says the September acquisition is excluded from reported capital-investment figures at $2.816 billion.
That figure is the reported acquisition amount, not an announced construction budget. The release does not identify new pipeline mileage, processing capacity, compression additions, customer commitments or contractor packages tied specifically to the acquired assets.
Transco and storage updates add incremental capacity
Williams identified several transmission and storage developments outside the Momentum transaction. The company announced a 9.4-Bcf Clay Basin storage expansion, a Transco Southeast Supply Enhancement II project of more than 150 MMcf/d and an 84-MMcf/d increase to Garden Connector capacity.
Williams also said four projects placed in service added a combined 413 MMcf/d of pipeline capacity. The current release does not allocate that completed capacity among the four projects or provide the individual locations, capital costs or contractor lists.
The announced Clay Basin and Southeast Supply Enhancement II scopes should be treated as company-reported development updates. The release does not state that the projects have received all permits, reached final investment decision or moved into construction.
Power development is a separate growth platform
Williams said Socrates’ Plato North Power project is on track for in-service by mid-November. The company characterized Socrates as its first of multiple power projects and said it expects to announce additional power projects as it commercializes them.
The release does not disclose Plato North’s generation capacity, customer, location-specific capital cost, technology configuration, EPC contractor or equipment suppliers. As a result, the in-service target should not be interpreted as confirmation of an undisclosed procurement package.
What could be involved as projects move into execution?
Allstream perspective: Depending on final design and approvals, gas transmission, storage, gathering and power projects can involve engineering and design, survey and right-of-way work, line pipe, valves and fittings, compression and electrical equipment, metering and controls, civil work, welding, hydrostatic testing, insulation, coating and painting, as well as equipment rental and construction support.
Those are potential work categories rather than announced awards. Williams has not identified the EPC contractors, line-pipe suppliers, compression vendors, electric-equipment providers or construction firms for the new project scopes described in this release.
Allstream perspective: Capital visibility is broad; project awards remain specific to later disclosures
Williams’ update is significant because it pairs a sizable 2026 growth-capital outlook with named progress in Haynesville gathering, interstate transmission, storage and power infrastructure. The completed Momentum acquisition and the 413-MMcf/d of placed-in-service capacity are operating milestones, while Clay Basin, Southeast Supply Enhancement II and additional power initiatives still require project-level execution detail.
For suppliers and contractors, the next decision-useful disclosures would include final investment decisions, regulatory milestones, project budgets, route and facility specifications, equipment orders, engineering awards and construction schedules.
