Know which of these units you can rely on Individual · $165/mo

Every reactor scored 0-100 on capacity factor, forced-outage days, streak length, refuel and startup speed, so a published date from a top-decile unit is read differently from one from a bottom-decile unit.

  • Operational Excellence per unit
  • Projected overrun days
  • Breaker-to-breaker streaks
  • Rank within reactor type and cycle length

PJM Outage Pipeline

Individual

When every unit in PJM comes off line next, on one timeline, with the utility's published dates and our projected ones side by side.

See PJM's outage pipeline Individual · $165/mo

The next eighteen months of outages for this market on a single chart, so overlapping refuelings are obvious before they bite.

  • Published + projected start dates
  • MW at stake per outage
  • Confidence on every date
  • Projected overrun days

PJM Fleet Operating Record

Individual

How the 31 reactors in PJM actually run, as a fleet: the average Operational Excellence score, forced-outage days per unit, how many are in a qualifying breaker-to-breaker run, and which unit in this market is the most and least reliable.
