The utility reported these figures to EIA with the IEEE 1366 standard. Methods differ between utilities. What SAIDI and SAIFI mean

For utilities using the IEEE method, a Major Event Day is any day that exceeds a daily SAIDI threshold called Tmed. Tmed is a duration statistic calculated from daily SAIDI values from the past five years. For utilities not using IEEE methods, Major Events are self-determined by the reporting utility.
