U.S. Power Outage Statistics, 2014–2024

Explore EIA's annual U.S. distribution-system SAIDI, SAIFI and CAIDI data from 2014 to 2024, with separate IEEE and Any Method series.

2024 IEEE SAIDI comparison: 662.6 minutes for all events and 131.6 without major event days

2024 IEEE SAIDI: left bar, all events, 662.6 minutes per customer-year; right bar, without major event days, 131.6 minutes per customer-year. These are separate published treatments.

Contents17

Compare annual outage minutes by state, then check the national record. EIA methods and major-event treatments stay separate. Latest published year: 2024; history: 2014–2024.

SAIDI measures minutes of non-momentary interruptions per customer-year. SAIFI measures interruptions per customer-year. CAIDI measures restoration minutes per interruption. An annual average is not the length of one outage or a forecast for your home.

National overview: latest year and first-to-last change

Each row is a separate population/treatment. Signed changes are derived: 2024 minus 2014 in the same units. This is not a causal or fixed-coverage trend estimate.

National findings, with arithmetic

  • Derived: IEEE all-events SAIDI rose 180.5% from 2014 to 2024. 662.6 − 236.2 = 426.4 minutes per customer-year. These are the first and last years, not the minimum and maximum.
  • Derived: the 2024 IEEE event-treatment gap is 531.0 minutes per customer-year. 662.6 − 131.6; 80.1% of the all-events value. This does not identify a cause.
  • Observed: IEEE all-events SAIDI is highest in this eleven-year snapshot at 662.6 in 2024 and lowest at 209 in 2015.
  • Derived, min-to-max only: 662.6 − 209 = 453.6 minutes; 217.0%. This is the 2015 minimum to 2024 maximum, not the first-to-last change.

Power outage minutes by state, 2024

These are observed EIA-published state aggregates, not our utility estimates. This view ranks IEEE SAIDI only. The state CSV preserves all three metrics and all five EIA series for 50 states, D.C. and the U.S. over 2014–2024. Blank source cells display UNKNOWN; numeric CSV fields are empty with per-metric status columns. Any Method is not blended into the IEEE ranking.

  • Observed, one year (2024): South Carolina has the most all-events outage minutes among the 50 states: 3155 minutes per customer-year. Derived 2014–2024 range for South Carolina: 122.9–3155. This single-year ranking does not establish a persistently worst state.
  • Observed, one year (2024): Arizona has the fewest: 83.6 minutes per customer-year. Derived 2014–2024 range for Arizona: 70.6–136.9; a single year is not a household forecast.
  • Observed, one year (2024): West Virginia has the highest without-major-event-days value: 486.1 minutes per customer-year. Derived 2014–2024 range for West Virginia, same treatment: 385.7–543.6.
  • Derived, one year (2024): South Carolina has the widest gap: 3155 − 115.9 = 3039.1 minutes per customer-year. Derived 2014–2024 range of annual gaps for South Carolina: 21.6–3039.1. This subtraction does not attribute the difference to weather.

National reference, same IEEE measures: all events 662.6; without major event days 131.6 minutes per customer-year. This is EIA's published national aggregate, not an average of states. Findings above exclude D.C.; the table labels it separately.

Reporting method, coverage and limits

EIA receives annual utility reliability reports on Form EIA-861. Its Electric Power Annual technical notes describe customer-weighted aggregates using customers reported for each metric. We transcribe EIA's published aggregates; we do not aggregate utilities, average states or estimate missing cells.

IEEE means IEEE 1366-2003 or 1366-2012. Any Method includes both IEEE and non-IEEE reporters and remains a separate population. IEEE major event days exceed the daily-SAIDI threshold Tmed based on the preceding five years; other-method major events are utility-defined. Loss of Supply Removed excludes interruptions from high-voltage/bulk-power supply and is not the without-major-event-days series.

These measures describe non-momentary interruptions. With/without major events is a statistical treatment, not a weather-only split. A single storm can dominate a state-year. A gap does not identify the contributing event or cause.

The aggregate tables do not provide each series/year's utility roster, metric-specific customer coverage, missing reporters or event-day list. Coverage and reporter mix can change. A state ranking describes the reported customer aggregate in one year, not every household or utility. Historical changes need not reflect a fixed population or steady trend. These are not real-time conditions, household risk scores, outage forecasts or battery-sizing instructions.

Report a correction: use the Plainly Prepared contact page; name the geography, year, metric, series and original EIA table cell. Corrections will identify the source version and date.

Sources, update record and citation

Original source: U.S. Energy Information Administration, Electric Power Annual, Form EIA-861. Data year 2024; released October 16, 2025; next scheduled release October 2026. National Table 11.1 was retained September 29, 2026. State Tables 11.4–11.6 and the official report technical notes were retrieved by unauthenticated public download October 1, 2026; files, URLs, times and SHA256 hashes are retained. They publish 2014–2024 in the same five labelled series. No earlier years are added by another method.

How to cite: Plainly Prepared, “U.S. Power Outage Statistics, 2014–2024,” compilation of EIA Tables 11.1 and 11.4–11.6, updated October 1, 2026, disaster-report.com/research/us-power-outage-statistics/. Credit EIA as original source; name geography, year, metric, method and event treatment. Label calculations derived and give their arithmetic.

After the next EIA release: retain the new source, reconcile definitions/coverage, regenerate CSVs/findings and repeat data/render review before publishing. This compilation does not claim that future update has happened.

Where outage statistics fit in a home power plan

Annual aggregates do not describe a specific home. Start with our generator and battery backup guide and power station versus generator comparison. Use appliance nameplates and maker instructions for equipment-specific planning.

Compare annual outage minutes by state, then check the national record. EIA methods and major-event treatments stay separate. Latest published year: 2024; history: 2014–2024.

SAIDI measures minutes of non-momentary interruptions per customer-year. SAIFI measures interruptions per customer-year. CAIDI measures restoration minutes per interruption. An annual average is not the length of one outage or a forecast for your home.

National overview: latest year and first-to-last change

Each row is a separate population/treatment. Signed changes are derived: 2024 minus 2014 in the same units. This is not a causal or fixed-coverage trend estimate.

National findings, with arithmetic

  • Derived: IEEE all-events SAIDI rose 180.5% from 2014 to 2024. 662.6 − 236.2 = 426.4 minutes per customer-year. These are the first and last years, not the minimum and maximum.
  • Derived: the 2024 IEEE event-treatment gap is 531.0 minutes per customer-year. 662.6 − 131.6; 80.1% of the all-events value. This does not identify a cause.
  • Observed: IEEE all-events SAIDI is highest in this eleven-year snapshot at 662.6 in 2024 and lowest at 209 in 2015.
  • Derived, min-to-max only: 662.6 − 209 = 453.6 minutes; 217.0%. This is the 2015 minimum to 2024 maximum, not the first-to-last change.

Power outage minutes by state, 2024

These are observed EIA-published state aggregates, not our utility estimates. This view ranks IEEE SAIDI only. The state CSV preserves all three metrics and all five EIA series for 50 states, D.C. and the U.S. over 2014–2024. Blank source cells display UNKNOWN; numeric CSV fields are empty with per-metric status columns. Any Method is not blended into the IEEE ranking.

  • Observed, one year (2024): South Carolina has the most all-events outage minutes among the 50 states: 3155 minutes per customer-year. Derived 2014–2024 range for South Carolina: 122.9–3155. This single-year ranking does not establish a persistently worst state.
  • Observed, one year (2024): Arizona has the fewest: 83.6 minutes per customer-year. Derived 2014–2024 range for Arizona: 70.6–136.9; a single year is not a household forecast.
  • Observed, one year (2024): West Virginia has the highest without-major-event-days value: 486.1 minutes per customer-year. Derived 2014–2024 range for West Virginia, same treatment: 385.7–543.6.
  • Derived, one year (2024): South Carolina has the widest gap: 3155 − 115.9 = 3039.1 minutes per customer-year. Derived 2014–2024 range of annual gaps for South Carolina: 21.6–3039.1. This subtraction does not attribute the difference to weather.

National reference, same IEEE measures: all events 662.6; without major event days 131.6 minutes per customer-year. This is EIA's published national aggregate, not an average of states. Findings above exclude D.C.; the table labels it separately.

Reporting method, coverage and limits

EIA receives annual utility reliability reports on Form EIA-861. Its Electric Power Annual technical notes describe customer-weighted aggregates using customers reported for each metric. We transcribe EIA's published aggregates; we do not aggregate utilities, average states or estimate missing cells.

IEEE means IEEE 1366-2003 or 1366-2012. Any Method includes both IEEE and non-IEEE reporters and remains a separate population. IEEE major event days exceed the daily-SAIDI threshold Tmed based on the preceding five years; other-method major events are utility-defined. Loss of Supply Removed excludes interruptions from high-voltage/bulk-power supply and is not the without-major-event-days series.

These measures describe non-momentary interruptions. With/without major events is a statistical treatment, not a weather-only split. A single storm can dominate a state-year. A gap does not identify the contributing event or cause.

The aggregate tables do not provide each series/year's utility roster, metric-specific customer coverage, missing reporters or event-day list. Coverage and reporter mix can change. A state ranking describes the reported customer aggregate in one year, not every household or utility. Historical changes need not reflect a fixed population or steady trend. These are not real-time conditions, household risk scores, outage forecasts or battery-sizing instructions.
