Motiva Port Arthur Refinery — Port Arthur, Texas
Overview
TYPE3’s map data identifies Motiva Port Arthur Refinery as a refining facility in Jefferson County, with coordinates 29.8990, -93.9520, city precision, Operating status, and a 200 MW seed estimate. Its note cites a February 2025 throughput expansion and describes Motiva as wholly owned by Saudi Aramco. TYPE3’s map data power figure is explicitly unconfirmed and must not be treated as a measured load.
Motiva’s current refining page identifies the Port Arthur refinery as North America’s largest and publishes 730,000 barrels per day of total throughput, plus 40,000 barrels per day of base-oil capacity. EIA’s refinery-ranking page, using January 1, 2026 operable capacity, lists Port Arthur at 656,400 barrels per calendar day. The difference is a measurement/date/scope conflict between operator-published throughput and EIA operable capacity; neither is electrical demand.
Motiva’s Port Arthur record holds the throughput conflict as a scope and date distinction pending reconciliation. TCEQ’s current pending application pages include Motiva Port Arthur Refinery and a Motiva cogeneration unit; those records support continuing regulatory and integrated-energy activity but do not quantify site demand, generation self-use, or flexible load. The refinery, chemicals plant, cogeneration, base-oil, throughput, and permit layers remain separate; barrels per day, acreage, and TYPE3’s 200 MW are not current-demand or availability measures. Current site demand, generation self-use, and flexible load remain unverified.
Questions
Is Motiva Port Arthur operating?
Yes. Motiva’s current operations pages describe the Port Arthur refinery and integrated chemicals complex as operating assets.
Why do Motiva and EIA show different barrel-per-day figures?
They describe different published measures and dates: Motiva states total throughput, while EIA lists operable atmospheric-distillation capacity as of January 1, 2026.
Does 200 MW represent the refinery’s demand?
No. TYPE3’s map data labels 200 MW an unconfirmed estimate; reviewed sources do not verify current electrical demand or available flexibility.
