What is the Western Gateway pipeline, and what is its planned timeline for operation?

The Western Gateway pipeline is a proposed fuel transportation project led by Phillips 66 and Kinder Morgan Inc. to ship gasoline and diesel from US Gulf Coast and Midwest refiners to California. It will involve building a new pipeline segment from Borger, Texas, to Phoenix; reversing the existing Gold Pipeline (Borger to St. Louis); and connecting to Las Vegas via Kinder Morgan’s CALNEV conduit. The project is slated to begin operations in mid-2029.

Why are Phillips 66 and Kinder Morgan advancing this pipeline now, and what regional fuel supply issue does it aim to address?

The pipeline is being advanced in response to sharply elevated gasoline and diesel prices in California and Arizona—driven in part by a recent loss of West Coast refining capacity, including the closure of two California refineries that reduced the state’s refining capacity by roughly 20%. This has increased the region’s dependence on fuel imports from other states and nations, creating a market need for a dedicated, reliable inland supply route.
