Phillips 66 (NYSE: PSX) and Kinder Morgan (NYSE: KMI) announced the advancement of the Western Gateway Pipeline project following a second open season that secured sufficient long-term shipper commitments to move forward.

The pipeline system will connect Midwest and Gulf Coast refinery supply to Phoenix, Arizona and California markets, with connectivity to Las Vegas, Nevada through Kinder Morgan's existing CALNEV Pipeline. The project will consist of a new pipeline from Borger, Texas to Phoenix, Arizona, combined with Kinder Morgan's existing SFPP pipeline from Colton, California to Phoenix, which will be reversed to enable eastward product flows into California.

The Western Gateway Pipeline will be supplied from Midwest and Gulf Coast sources connected to Borger, Texas. Phillips 66's Gold Pipeline, which currently flows from Borger to St. Louis, will be reversed to enable refined products from Midwest and Gulf Coast refineries to flow toward Borger and supply the Western Gateway system.

"Customer response during the open season underscores the importance of Western Gateway in addressing long‑term refined products logistics needs in the region," said Phillips 66 Chairman and CEO Mark Lashier.

Kinder Morgan CEO Kim Dang stated the company is positioned to support the transportation solution by utilizing existing pipeline assets across multiple states along the route.

The project targets a mid-2029 in-service date. The advancement remains subject to the execution of definitive transportation service agreements, joint venture agreements, and respective board approvals from both companies.

The information is based on a joint press release from the companies.
