The Operating Record
Reliability Board
44 operating reactors in Duke Progress, PJM, SPP, FPL, ISO-NE, scored on how they actually run and ranked
against each other. Built from 27 years of daily reactor records.

Individual · $165/mo
One 0-100 score per unit, with sub-scores for reliability, efficiency and discipline, ranked against the fleet and against comparable units rather than against the whole fleet.
- 44 units scored and ranked
- Capacity factor and forced-outage days
- Breaker-to-breaker streaks
- Ranked against comparable units, not the whole fleet

Rel / Eff / Disc are the three sub-scores behind the composite: whether a unit stays on line,
whether it uses fuel and outage time well, and whether it comes back cleanly.

By Market
how a reactor in each market typically behaves| Market | Units | GW | Avg score | Forced d / unit | B2B champions | Avg overrun | Best | Weakest |

Averages are unweighted across the units in each market. Capacity weighting would let two large
reactors answer for a whole market; this column answers "how does a unit here typically behave", which is the
question the heading asks.
A good record is not the same as a firm date

The reliability score says how a unit behaves. The risk radar says what that behavior is about to cost: projected overrun days on every upcoming outage, and the megawatt-days the market has not priced.
