How often is the power out?
Type a ZIP code or pick a county to see how many minutes a year its customers went without power, how many outages they had, and how long a typical one lasted, 2013–2025, from each utility's own filing with the U.S. Energy Information Administration.

Minutes without power per year, by county
Average over 2021–2025 of the utilities serving each county, each weighted by its total customers (EIA does not say how many it serves in the county, so a large utility that touches a corner of a county can dominate its figure). Darker means more time without power. Hover for the figure; click to look the county up.

States, ranked by time without power
Customer-weighted average minutes per customer per year, 2021–2025. The U.S. figure for the same years is 400 minutes with major events and 121 without. The worst year nationally in this span was 2024 (598 minutes).

How to read these numbers
- Minutes without power per year is SAIDI: the total customer-minutes of sustained interruption in the year divided by customers served. 240 minutes means the average customer was dark four hours that year, whether in one storm or forty short outages.
- Outages per year is SAIFI: sustained interruptions (longer than five minutes under IEEE 1366) per customer. Minutes per outage is CAIDI, which is SAIDI ÷ SAIFI: the average length of an interruption.
- Major events are days a utility's outage minutes exceed its own statistical threshold (IEEE 1366's 2.5-beta method): hurricanes, ice storms, Winter Storm Uri in 2021. "Without major events" shows the everyday reliability of the wires; "with" shows what customers lived through.
- Utility, not place. Each utility files one set of figures for its whole system. A ZIP served by Oncor shows Oncor's system-wide numbers. A county with three utilities shows each one; the blended figure weights them by their total customers that year, not by how many they serve in that county (EIA does not publish that), so a large utility that serves a corner of the county can dominate the blend. Open "Utilities behind these numbers" to see each one. A quiet neighborhood and a storm-hit one on the same utility show the same figure.
- Two standards. Most utilities report under IEEE 1366; some report under their own definitions (EIA publishes both and the page marks which). Utilities with no figures in EIA's file (short-form filers and wholesale-only utilities are not asked for them) show as "no reliability figures".
- Minutes are rounded; a dash means the utility did not report that year. EIA's annual file arrives each autumn, about ten months after the year ends.
