Aug 11 (Reuters) – Phillips 66, Kinder Morgan and HF Sinclair said on Tuesday they have decided to proceed with the proposed $5 billion Western ​Gateway Pipeline system and finalized a joint venture agreement ‌for the same.

Phillips 66 will own 49.9% of the venture, Kinder Morgan 35.1% and HF Sinclair 15%.

Companies have been racing to build a major new fuel pipeline to the U.S. ‌West ​Coast ahead of planned refinery closures ⁠in California, a relatively ⁠isolated fuel market with limited links to major refining hubs that leave it vulnerable to supply disruptions and price spikes.

Western Gateway is a proposed 1,300-mile ​refined products pipeline system with a design capacity of 230,000 barrels per day that would establish ⁠a new fuel supply route ⁠from St. Louis, Missouri and Gulf Coast ​origin points to Arizona and California.

Phillips 66’s Gold Pipeline, ​which currently runs from Borger, Texas to St. ‌Louis, will be reversed to supply the proposed east-to-west system, as will Kinder Morgan’s existing pipeline between Colton, California and Phoenix, Arizona.

Meanwhile, after the completion of a ⁠new pipeline from Borger to Phoenix, Kinder Morgan’s existing SFPP East Line and West Line assets will be contributed ⁠to the joint ‌venture at a value of about $1.5 ⁠billion, the companies said.

Phillips 66 will contribute ​nearly $2.5 ‌billion in cash for the project — ​which has ⁠an estimated enterprise value of $5 billion — while Kinder Morgan will contribute about $250 million and HF Sinclair about $750 million.

The new system would be underpinned by primarily 10-year, take-or-pay contracts, they added.
