Planned vs Unplanned Outages

Planned turnarounds are scheduled 12–24 months in advance for inspection, maintenance, and equipment replacement. They typically last 20–60 days and represent the largest vendor procurement windows. Unplanned outages result from equipment failure or regulatory action and are not shown here. This calendar covers planned maintenance outages only, with confidence ratings for each event.
