Phillips 66 and Kinder Morgan, Inc. have announced they are moving forward with the Western Gateway Pipeline, a proposed refined products pipeline system connecting Midwest and Gulf Coast refinery supply to markets in Arizona, California, and Nevada. The advancement follows a successful second open season that secured sufficient long-term shipper commitments to progress the project, subject to the execution of definitive transportation service agreements, joint venture agreements, and respective board approvals.
Addressing Long-Term Logistics Needs on the West Coast
The project is designed to improve supply flexibility and reliability for West Coast markets, which have historically faced refined products logistics constraints. Phillips 66 Chairman and CEO Mark Lashier pointed to strong market interest as validation of the project’s strategic importance. “Customer response during the open season underscores the importance of Western Gateway in addressing long-term refined products logistics needs in the region,” he said, adding that demand during the process confirmed the role the pipeline can play in strengthening regional supply chains.
Kinder Morgan CEO Kim Dang highlighted the company’s ability to leverage existing infrastructure across the route. “By utilising existing pipeline assets across multiple states along the route, we’re uniquely well-positioned to support a refined products transportation solution,” she said.
A Multi-State Infrastructure Solution
The Western Gateway Pipeline will combine new-build infrastructure with existing assets from both companies. A newly constructed pipeline will run from Borger, Texas to Phoenix, Arizona, while Kinder Morgan’s existing SFPP, L.P. pipeline between Colton, California and Phoenix will be reversed to enable east-to-west product flows into California. Connectivity to Las Vegas, Nevada will be provided via Kinder Morgan’s CALNEV Pipeline.
To feed the system, Phillips 66’s Gold Pipeline — which currently runs from Borger to St. Louis, will also be reversed, allowing refined products from Midwest and Gulf Coast refineries to flow toward Borger and into the Western Gateway system.
The project is targeting an in-service date of mid-2029.
