The Shifting Sands of US Refining Capacity

Refining Capacity Reduction

Ah, the ongoing tale of US refining capacity. In 2024, things took a slight dip, with capacity trimmed by 43,000 barrels a day, bringing the total to 18.3 million barrels. This report, courtesy of the Energy Information Administration, provides a yearly industry snapshot, revealing the complex shifts within this dynamic sector.

A Rollercoaster Five Years

Over the past five years, US refining capacity has been a bit of a rollercoaster. The pandemic brought a drastic drop in demand, which led to closures and a dip below 18 million barrels for the first time since 2014. Despite major expansion efforts by companies like ExxonMobil, Valero Energy, Marathon Petroleum, and Citgo, we’re once again seeing a decline.

Refinery Closures

Since January, LyondellBasell’s Houston plant, with a capacity of 264,000 barrels a day, shut its doors. Similarly, Phillips 66 has plans to close its Los Angeles facility by the year’s end. Valero will follow suit by 2026 with their Benicia refinery in California. These closures reflect a longstanding trend, where smaller, less profitable refineries face significant challenges.

Effects on Fuel Production

These California closures could push the nation’s fuel capacity to pandemic-era lows, roughly 17.8 million barrels per day. It’s a scene reminiscent of times past, though it’s not all gloom.

The Gulf Coast’s Mega Plants

While some refineries close, others thrive. On the Gulf Coast, larger facilities bolster their presence. Motiva’s Port Arthur, Texas, refinery now boasts an impressive 641,000 barrels a day, surpassing Marathon’s Galveston Bay plant and becoming the nation’s largest.

Saudi Aramco’s Strategic Moves

Saudi Aramco’s Motiva continues its upward trajectory, pushing capacity at its Texas plant to a remarkable 651,000 barrels a day in December. As the sole US refinery operated by Aramco, it highlights a strategic focus on larger, more complex operations.

Conclusion

In conclusion, US refiners face a fluctuating landscape, influenced by both local and global factors. As smaller operations close, large-scale facilities continue to expand, reflecting a broader trend towards centralisation and efficiency.
