About this ranking: SAIDI values are customer-weighted averages across utilities in each state that reported reliability data to EIA Form 861. States with fewer reporting utilities may not represent every customer. See the methodology page for IEEE Standard 1366 definitions and major-event-day treatment.

According to the U.S. Energy Information Administration (EIA), electric utilities publish SAIDI and SAIFI reliability metrics in Form 861 annual filings. Every figure on PlainUtility is rebuilt from those federal tables; no number is typed in by an editor. State SAIDI averages are computed directly from EIA Form 861 reliability files, no ranking figure is typed by an editor.
