Phillips 66 and Kinder Morgan Expand Western Gateway Pipeline Capacity
Event summary
- Phillips 66 and Kinder Morgan launch a second open season for the Western Gateway Pipeline, offering remaining capacity and expanded origins/destinations.
- The pipeline will connect Midwest refinery supply to Phoenix, Arizona, and California, with additional access to Los Angeles via a reversed SFPP line.
- The second open season runs from January 16, 2026, to March 31, 2026.
- The Western Gateway Pipeline will consist of a new-build pipeline from Borger, Texas, to Phoenix, combined with Kinder Morgan’s existing SFPP pipeline.
The big picture
The expansion of the Western Gateway Pipeline reflects the ongoing need for robust infrastructure to transport refined products from the Midwest to high-demand markets in the Western U.S. This project is part of a broader trend of midstream energy companies investing in pipeline capacity to meet growing logistics needs and supply diversification. The strategic anomaly here is the addition of new access points and the reversal of existing lines, which could significantly alter the flow dynamics of refined products in the region.
