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
- Share
- URL copies the pair you picked
Figures use the portal's global MAX(year) reliability cohort, the same bar as utility detail pages.
