Live Nuclear Fleet Outage Tracker

Current live status, power levels, and scheduled outage updates for the US commercial nuclear fleet. Data refreshed 1.2h ago

? Percentage of total fleet capacity currently online and generating power. Grid Capacity 88.1% ? Units currently in a scheduled refueling or maintenance outage (Spring 2026). Outages 34

? Units currently at 0% power (likely in an outage or shutdown). Offline 7

? Units operating between 1-99% power (excluding known startups or coastdowns). Reduced Power 4

? Units nearing the end of their fuel cycle, gradually lowering power before an outage. Coasting 0

? Units in the process of increasing power following an outage or scram. Startup 3

? Units on a qualifying Breaker-to-Breaker run — continuous operation exceeding their cycle-adjusted threshold with no trips to 0% power. B2B 4
