EIA Form 861 · 2023 · highest SAIDI first

States with the worst electric outages

Customer-weighted state averages sorted by interruption duration. Higher SAIDI means more outage minutes per customer per year, often storm exposure plus rural geography, not a single ownership verdict.

Answer first

Maine posts the highest customer-weighted state SAIDI at 1863.0 minutes in the 2023 EIA filing; the fifth-highest sits at 866.4 minutes versus a national utility average near 341 minutes.

Three structural drivers of high SAIDI

High-SAIDI states usually combine storm exposure, long rural feeders, and aging overhead plant , often well above the ~362-minute unweighted mean across reporting states in this table. A single active storm year can move rankings several places, multi-year reads beat one EIA release. Cross-check most-reliable states and the SAIDI/SAIFI explainer.

Why do some states have more outages? Rural territories, severe weather, older overhead plant, and cooperative-heavy mixes tend toward longer restoration. Figures here exclude major event days at the utility level where reported.
