The West Coast energy market, PADD 5, is undergoing a profound transformation. Consumption of petroleum-based refined products is declining due to a host of factors including increased renewable diesel (RD) usage, slowing population growth, electric vehicle (EV) penetration and fuel efficiency improvements, just to name a few, but that’s only half the story. Further upping the stakes, crude oil production in the region has declined faster than downstream consumption, so it has had to increasingly rely on imported barrels to support its dwindling refinery throughput. In today’s RBN blog, we look at how the West Coast’s supply of refined products and crude oil has evolved over time and why its reliance on imports has grown.
In Part 1 of this series, we explained how the U.S. is divided into five Petroleum Administration for Defense Districts, or PADDs (see Figure 1 below). The East Coast’s population density makes it the largest consumer of refined products but, with no production to call its own, PADD 1 relies on imported crude oil to supply its shrinking refinery base. In Part 2, we put the spotlight on imports of Canadian crude oil and how critical they are to refineries in the Midwest and Great Plains. Most Canadian exports come through PADD 2 pipelines, and its 25 refineries (combined capacity of 4.3 MMb/d) are, in many cases, significant consumers of heavy and light crudes from the Great White North. In Part 3, we discussed the Gulf Coast — by far the biggest crude oil producing and refining market in the U.S. Its sheer size makes it critical in balancing crude oil and refined products markets, with its refineries being on average the most efficient in the world with ample export opportunities. Most recently, in Part 4, we addressed the importance of rising crude production from shale basins in and around the Rockies and how it has contributed to greater volumes being pushed toward the Cushing, OK, storage hub.

Today we finish off our series by focusing on PADD 5, which stretches from the island-studded waters of the Puget Sound to the sun-speckled glitz of Southern California and the deserts of Nevada and Arizona, with Alaska and Hawaii thrown in for good measure. The petroleum markets of PADD 5 are just as diverse as its geography, with plenty of refined product consumption to go around, although its 2.6 MMb/d of demand makes it the second-lowest consuming region in the U.S., way ahead of PADD 4 but behind PADDs 1, 2 and 3. The majority of the region’s population resides in California, which was once the nation’s largest oil-producing state following the discovery of oil in the San Joaquin Valley and Los Angeles in the late 1800s. Since the Shale Revolution unlocked the resource potential of other states, California has been left behind in terms of its significance as a producer, primarily due to a hostile regulatory environment that discourages investment, particularly in the petroleum sector. At the same time, crude oil production in Alaska has started to show its age, with output in the state experiencing a steady decline. This trend in Alaska may be about to reverse, as we noted recently in Take It On The Run, but PADD 5 will continue to lag behind all of the other oil-producing regions.
