On October 29, LyondellBasell signed an agreement to sell its Houston refinery and related assets to Valero Energy for $320.5 million, with the transaction expected to close by the end of 2026. The refinery had already been idle since March 2025. It has a former processing capacity of about 264,000 barrels per day and sits on 700 acres adjacent to Valero’s existing refinery on the Houston Ship Channel.
Valero’s CEO said the purchase price is a small fraction of replacement cost. A 264,000-barrel-per-day refinery with 13.5 million barrels of storage and dock and rail facilities would cost far more than $320 million to build from scratch. Valero has an existing 205,000-barrel-per-day refinery next door, allowing it to share docks, pipelines, and utilities, with very low integration costs. The company plans to restart 165,000 barrels per day of light sweet crude processing capacity by the end of 2027, and will later evaluate investment in heavy sour units. It will restart about 60% first and decide on the remainder based on spreads.
LyondellBasell announced its exit from the refining business in April 2022 and formally halted operations at the plant in February 2025, laying off 345 workers, or 86% of the site’s workforce. Since then, the refinery has remained on the balance sheet, generating no revenue while continuing to consume management resources and fixed costs. The sale is expected to improve cash flow by $50 million to $100 million per year. The $320 million price tag itself is not the main point; the key is divesting an asset that generates no revenue.
Viewed together, the two sides’ choices show that the U.S. refining industry is turning. In recent years, as fuel efficiency improved and the energy transition advanced, refiners kept shutting capacity, with plants exiting in California and along the Gulf Coast. But the Russia-Ukraine conflict and Middle East tensions disrupted refined product supply, pushing up diesel, jet fuel, and gasoline prices, and refiners such as Valero posted record profits in October. Industry observers believe the deal signals a nascent recovery in refining and that the shutdown trend may be reversing.
LyondellBasell is not a refiner, and it had no capacity to cash in on this profit window. Valero is a refiner, and what it needs is capacity adjacent to its existing system that can be restarted quickly, not a new refinery. On the same piece of land, one side saw a disposal item after exit; the other saw an opportunity for low-cost capacity expansion.
