Source: U.S. Energy Information Administration, Form EIA-861 (final 2025 data). Minutes a year (SAIDI). SAIDI is the average minutes a customer is without power in a year, SAIFI the number of interruptions, and CAIDI the average minutes for each interruption. Major event days are left out.

What the gap means in dollars and minutes

District of Columbia customers lost power for about 34 minutes a year on average, or 0.6 hours, and West Virginia customers for about 498 minutes, or 8.3 hours. Spread over a year, that is 0.1 minutes a day against 1.4. These averages leave out major event days, so a hurricane or ice storm year can be far worse than the number shows. See ways to lower your bill and plan for outages if you rely on medical equipment.

What sits behind the order

SAIDI is the average number of minutes a customer is without power in a year. It counts outages with major event days, such as large storms, left out, so it shows everyday reliability rather than disaster years. The ten places with the fewest outage minutes average 65 minutes, and the ten with the most average 251. Differences come from weather, tree cover, how lines are built, how far customers live from each other and how each utility reports.

Utilities report under different standards, and a state's total blends them, so treat close ranks as ties. For one utility's numbers, see its profile on the electric companies pages.

How the ranking is built

The ranking uses the final 2025 EIA-861 data that the rest of Kilowatt Atlas uses. Average price is the revenue utilities and suppliers collect from residential customers divided by the kilowatt-hours sold, so it includes fixed charges. Average use is residential kWh per customer per month, and the bill is price times use. Places tie only if their values match exactly. Read the full methodology.

Statewide averages are not your bill

A state average hides large differences between utilities, home types and plans. Your own price and use decide your bill. See whether your bill is normal.

About this ranking

Which state is first in this ranking?

District of Columbia ranks first with 34 min, and West Virginia ranks last with 498 min.

Where does the data come from?

From EIA Form EIA-861 final 2025 data, released October 7, 2026. Reliability figures come from the same survey and leave out major event days.

How often is this ranking updated?

When EIA publishes new final data, once a year. The ranking shows 2025 data until then.

Does a higher rank mean a better state?

No. A rank describes one number. Prices, bills, use and reliability each reflect different things, and a place with a high bill may also have high use or a hot or cold climate.
