How these numbers are made
Utilities report reliability every year to the U.S. Energy Information Administration on form EIA-861. We use the values with major event days (storms, wildfires, heat waves), because that is what customers live through. Where EIA publishes a state total we use it; otherwise the state figure is the average of its utilities weighted by customers.
The US average is our calculation: the state figures weighted by each state's customers. It can differ slightly from national figures EIA publishes elsewhere. The figures are yearly averages; a single outage in your area can last much longer. To size backup for the outage you want to ride through, use the calculator.
FAQ
How many hours was the average American without power in 2025?
4.4 hours, counting major storms: the average of the 50 state figures weighted by their 149 million customers, from utility reports to the EIA (form 861). The median state saw 4.3 hours.
Which state had the most power outages in 2025?
West Virginia: 16.9 hours without power per customer, 3.1 interruptions on average. Next: Michigan (11.2 h) and Nebraska (9.1 h).
Which state had the fewest outage hours in 2025?
Arizona and Florida: 1.2 hours per customer.
Are power outages getting worse?
They swing with storms more than they trend. The customer-weighted US figure was 8.2 h in 2020, 7.4 h in 2021, 5.6 h in 2022, 5.7 h in 2023, 10.2 h in 2024, 4.4 h in 2025. In 2025, 18 of 50 states had more outage hours than the year before.
What is SAIDI?
System Average Interruption Duration Index: total minutes of sustained interruption per customer per year, reported by utilities to the EIA (form 861). We show the value including major event days, which is what customers actually experience.
Which number should I use to size a battery?
Not the yearly average: size for the longest single outage you want to ride through. The average outage length per state is in the table; the calculator turns your appliances and hours into battery and generator size.
