Valero sees LyondellBasell’s former Houston refinery as a chance to strengthen its Gulf Coast network, with a partial restart planned by the end of 2027.
Why the refinery closed
LyondellBasell closed the refinery in early 2025, ending operations at a site that had processed crude since 1918. It could handle nearly 264,000 barrels a day and produce gasoline, diesel and jet fuel. Bloomberg reported that keeping it competitive could require as much as $2 billion in upgrades. Newer Houston-area refineries had been retooled to process abundant Permian Basin crude. LyondellBasell had tried and failed to sell the plant before leaving refining.
LyondellBasell wanted to focus investment on chemicals and circular, lower-carbon businesses. It first planned to close the Houston operation by the end of 2023, then delayed its exit after favorable inspections and reliable performance made it reasonable to keep running with moderate maintenance spending. The delay showed the plant could still earn money, but did not remove the expected cost of major upgrades.
What Valero expects to gain
The roughly 700-acre property sits beside Valero’s existing Houston refinery on the Ship Channel. It includes storage and marine, rail and truck connections. Valero says integrating the site could improve its flexibility in sourcing crude and help address a shortfall in intermediate feedstocks it otherwise buys from third parties. These are the company’s claims about the deal’s benefits, not demonstrated results.
Valero expects to restart 165,000 barrels per day of light-sweet crude processing by the end of 2027. That is less than the former refinery’s nearly 264,000-barrel daily capacity. It is crude throughput, not a promise to produce 165,000 barrels of finished fuel each day. Valero describes future investment in heavy-sour crude processing as an opportunity, not a committed second phase.
Market prospects and restart costs
Conditions are favorable for refiners, but that does not prove a temporary price spike caused Valero’s decision. Valero reported record third-quarter 2026 profits as disruptions linked to conflicts in Iran and Ukraine lifted refining margins. Those conditions could change before the Houston plant is ready. U.S. exports of gasoline, diesel and jet fuel averaged 2.4 million barrels a day in 2025. The Ship Channel’s docks connect the site to global buyers and domestic customers.
The purchase price is not the full cost of restarting the refinery. Valero has not announced a complete restart budget. Equipment that has been shut down and decommissioned must be inspected, prepared and operated safely before production resumes. LyondellBasell says Valero will take on ongoing site operations, environmental liabilities, pension costs and related employee obligations.
Jobs, approvals and next steps
The shutdown led LyondellBasell to announce layoffs affecting about 345 employees. The company now says the sale provides continued employment for the site’s workforce, but it has not said how many jobs will remain or what staffing will look like when refining resumes. Nearby communities could see industrial jobs and economic activity, along with renewed refinery emissions and safety concerns. The public deal announcement does not give a complete timetable for environmental and permitting steps.
Valero expects the deal to close by the end of 2026, subject to antitrust review and other customary conditions. After closing, the test will be whether the partial restart can happen by the end of 2027 at a cost that supports Valero’s expected return. LyondellBasell can leave a business outside its main focus, while Valero gains a neighboring site that may strengthen its network. The outcome will depend on fuel demand and the cost of bringing an old refinery back to life.
