The Operating Record
Reliability Board
62 operating reactors in PJM, SRP, Southern, ISO-NE, Duke Progress, MISO, 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.
- 62 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.

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
Pro · $499/mo
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.
