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.

  • 16 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. Scores recomputed today; the underlying daily reactor record updates every morning. Click any column heading to re-rank.

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.

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.
