About this data

Each row is the status ISO New England publishes for a reported area, with the operator action description and the time of the status. The text is an operator status and not a numeric reliability probability. It is useful as a record of when New England operators moved into or out of a heightened condition.

What people use it for

  • See what condition ISO-NE operators have declared
  • Find when a heightened system status began and ended
  • Add operator context to a New England price spike
