Per-Dimension Percentile Breakdown

Dimension Quad Cities 1
Capacity Factor 5-year average capacity factor — total generation as a fraction of installed capacity. Higher is better; top operators sustain 92%+.
88
95.2%
Forced Outage Days/yr 5-year forced outage days per year (annualised) — non-power days NOT explained by scheduled refueling. Lower is better.
68
2.2d
B2B Avg Streak Average breaker-to-breaker continuous-operation days across this unit's qualifying B2B runs (lifetime). Higher is better; reflects sustained reliability.
79
694d
Fuel Utilization Average in-cycle capacity factor (3-year). Fraction of each refueling cycle that produced full power. Higher = more efficient operator.
53
98.1%
Refuel Duration 5-year median scheduled refueling outage duration in days (refuel-shaped outages, 14-90d). Lower = faster turnaround.
85
21d
Startup Duration Robust mean days from first power post-refuel to sustained ≥95% power. Lower = faster ramp.
78
3.4d
Scrams (5-year) Scrams per year, computed over the 5-year window (annualised so windows are comparable). Lower is better; reflects operating discipline and equipment reliability.
