Monthly Outage Reports

Monthly outage reports

Please note the year-to-date SAIDI, CAIDI, and SAIFI, summaries at the bottom of each monthly report. They are industry measurements of power reliability.

  • SAIDI (System Average Interruption Duration Index) is the average outage duration per consumer. This is listed in minutes on the PRECorp form.
  • CAIDI (Customer Average Interruption Duration Index) is generally considered the average restoration time and is shown in minutes on the PRECorp form.
  • SAIFI (System Average Interruption Frequency Index) is the average number of outages or power interruptions a PRECorp customer would experience.
