Customer-weighted state averages of interruption duration. Lower SAIDI means fewer outage minutes per customer per year, not storm resilience or equity-weighted reliability.

Answer first

District of Columbia leads at 71.9 minutes average SAIDI in the 2023 EIA filing; the top-5 cutoff is 104.6 minutes versus a customer-weighted national utility average of 341 minutes.

How states earn the top reliability spots

The lowest-SAIDI states tend to share dense territories that shorten restoration travel, milder storm seasons (fewer Major Event Day spikes), and capital-heavy ownership mixes that fund hardening. A second pattern: states where one or two utilities serve most customers often beat states with hundreds of small rural reporters, scale helps mutual-aid and outage software. Drill from any state row to its utility table; within-state spread is often as wide as between-state spread.

What SAIDI does not capture

State averages say nothing about when outages hit, how the longest event felt, or distribution across customer classes. Time-of-day and equity-weighted metrics live in PUC dockets, not EIA Form 861. See the SAIDI/SAIFI explainer and methodology.
