States Ranked by Utility Reliability

Average SAIDI (minutes of customer outages per year) across all reporting U.S. electric distribution utilities in each state, drawn from the U.S. Energy Information Administration EIA Form 861 2020-2023 releases (918 utilities, last refreshed June 2026). According to the EIA, the national nMED (no-major-event-day) SAIDI average has held in the 135-146 minute range across that reporting window (excluding major event days). Lower SAIDI = more reliable. See our methodology for refresh cadence and IEEE Standard 1366 definitions.

About this ranking: SAIDI values shown are averages across all utilities in each state that reported reliability data to EIA Form 861. States with fewer reporting utilities may not represent all customers. Major event days (storms, hurricanes) are included in these figures.
