On April 20, 2026, Phillips 66 (NYSE: PSX) and joint venture partner Kinder Morgan (NYSE: KMI) announced they will move forward with development of the Western Gateway Pipeline, a long-haul refined products transmission system, after securing sufficient long-term shipper commitments during a second
Key Developments
The Western Gateway Pipeline will connect Gulf Coast and Midwest refinery supply hubs to high-demand markets in Arizona, California, and Las Vegas, Nevada via Kinder Morgan’s existing CALNEV Pipeline. The system will include a new greenfield pipeline segment running from Borger, Texas to Phoenix, Arizona, paired with the reversal of two existing assets: Kinder Morgan’s SFPP pipeline between Colton, California and Phoenix to enable east-to-west product flows into California, and Phillips 66’s Gol
Market Impact
For PSX, the project expands its fee-based midstream revenue base, reducing the firm’s overall exposure to volatile refining and commodity price cycles, while supporting its downstream marketing division by opening new, underserved West Coast distribution channels. For KMI, the project drives higher utilization of existing underused pipeline assets, expanding its share of the $45 billion annual U.S. refined products transportation market. For regional energy markets, the pipeline is projected to
In-Depth Analysis
West Coast refined product markets have faced persistent supply constraints over the past three years, with average retail gasoline prices running 32% above the U.S. national average between 2023 and 2025, driven by limited in-state refinery capacity and lack of long-haul transmission capacity from low-cost Gulf Coast hubs. By leveraging existing assets for roughly 45% of the project’s total route, PSX and KMI are positioned to reduce total project capex by an estimated 28% compared to a fully greenfield build, pushing projected internal rates of return (IRR) to a midpoint of 9%, in line with regulated midstream sector benchmarks. The secured long-term shipper commitments, which typically cover 85% of pipeline capacity for 10 to 15-year terms, significantly de-risk the project’s long-term revenue profile. That said, remaining headwinds include California environmental permitting requirements, potential local regulatory pushback, and final board approval, which could delay launch or increase costs. We maintain our neutral rating on PSX, as the project’s financial contributions will not materialize until 2029 at the earliest, with near-term earnings still dominated by refining margin volatility.
