Head-to-head compare · EIA Form 861 · 2023

Compare utilities side by side

Pick two electric utilities from the same federal reliability cohort and read SAIDI, SAIFI, and customer scale on one board, shareable, bookmarkable, no account required.

Why compare two utilities

SAIDI answers duration, SAIFI answers frequency, and customer count shows scale, together they separate a large IOU from a small cooperative serving the same state.

SAIDI
Outage minutes per customer-year
SAIFI
Outages per customer-year
