Generation outages

Generation outage reports from the seven US ISOs: unit events in some markets, outage MW by type in others, with every report kept as a vintage.

Updated November 2, 2026

About the data

Unit or equipment outage events in some ISOs, aggregate outage MW by type in others. Every report is kept as a vintage: a later report replaces an earlier one for the same interval, and reports published before an interval are kept as forecasts of it.

Plants with an active outage show a ring on the map, and the plant panel shows an outage history strip.

Sources

  • Generation outage reports, CAISO, ERCOT, ISO-NE, MISO, NYISO, PJM and SPP

Periods and update notes for each source are on Data sources.

Known gaps

Limits
  • An outage linked to a plant is a match on the published unit name, not a confirmed cause of lower output.
  • Transmission outages are not public in CAISO, ERCOT, MISO or PJM.

Missing values stay missing: a null means the source has no usable record, never zero. Zero and negative values are shown as reported.

Questions it answers

  • How many MW of generation were on outage in ERCOT each day last week, by category?
  • Which CAISO units reported the largest outages this month?
  • Which outages were reported at a given CAISO plant over the last year?
