(October 27, 2025) -- Phillips 66 and Kinder Morgan, Inc. have announced the launch of a binding open season for transportation service on the Western Gateway Pipeline. This proposed refined products system will move fuel from Texas to key markets in Arizona and California, with connectivity to Las Vegas through Kinder Morgan’s CALNEV Pipeline.
The open season began at 12:00 p.m. Central Time on October 20 and will close at 12:00 p.m. Central Time on December 19. During this period, interested shippers may request additional information by emailing [email protected].
As proposed, the Western Gateway Pipeline is designed to be an approximately 1,300-mile liquid products pipeline consisting of a new-build line from Borger, Texas, to Phoenix, Arizona, combined with Kinder Morgan’s existing SFPP, L.P. (SFPP) pipeline from Colton, California, to Phoenix, which will be reversed to enable east-to-west product flows into California. The Western Gateway Pipeline will help diversify Western energy markets with a reliable fuel source from the Midcontinent region.
With California’s refining footprint narrowing and Arizona’s fuel demand booming, securing America’s energy future is paramount. This means adding more capacity through resilient infrastructure and diversified supply. A Midcontinent-to-California corridor enhances reliability, reduces the risk of supply disruptions, and supports continued economic momentum across the region.
A partnership between Phillips 66 and Kinder Morgan, the Western Gateway project will create incremental refined product capacity from Borger, Texas, to Arizona and California. The system will include the new-build Borger–Phoenix segment and the reversed SFPP pipeline to expand supply flexibility and system redundancy.
The pipeline will be supplied from Borger as well as connections to the SFPP system in El Paso. In addition, Phillips 66’s Gold Pipeline, which currently runs from Borger to St. Louis, will be reversed to enable midcontinent refinery products to flow toward Borger and feed the Western Gateway system.
