Marathon Petroleum Temporarily Closes Catlettsburg Refinery Amid Power Interruption
February 24, 2026

Marathon Petroleum has temporarily shut down its Catlettsburg crude oil refinery in Boyd County, Kentucky, following a third-party power interruption, according to an official statement from the company. The outage triggered operational challenges, necessitating the use of flaring—a safety measure to combust excess materials under abnormal conditions. The company confirmed no injuries were reported, and all personnel and contractors are accounted for.

As a precaution, air quality monitoring is underway in the surrounding community. While initial readings show no public health risks, Marathon noted reports of odors and emphasized continued vigilance. The company prioritized safety, environmental stewardship, and community well-being in its response.

The shutdown is expected to last 2–3 weeks, according to the writing topic, though the provided sources do not specify the duration. This unplanned halt could disrupt regional refining capacity, potentially affecting supply chains and local fuel prices. Analysts may assess the broader implications for Marathon's operations, particularly if the outage impacts quarterly production targets or maintenance schedules.

Third-party infrastructure failures, such as power interruptions, highlight vulnerabilities in energy sector logistics. Investors may monitor Marathon's contingency plans and the refinery's restart timeline for insights into operational resilience. The company has not disclosed financial estimates related to the shutdown.

This incident underscores the interdependence of energy infrastructure and the risks posed by external disruptions. Updates on environmental monitoring results or operational progress will likely shape further market reactions.
