As of December 1, 2025, an Energy Information Administration (EIA) report found that Americans lost more power last year than any year in the previous decade. [1] US electricity customers experienced an average of 11 hours of power outages in 2024, which is almost twice as many as the annual average across the previous decade. [2] The leading cause for 80% of those hours were hurricanes, with major ones like Beryl, Helene, and Milton causing most of last year’s outages. The report builds on a growing body of evidence that extreme weather is taking a heavier toll on the electric power system in certain parts of the country. An October report by JD Power found that the average length of the longest outages has increased. Hurricane Helene especially caused severe damage to utility systems in the US Southeast and Mid-Atlantic. South Carolina, North Carolina, and Florida faced strong winds and flooding from the hurricane that affected transmission and distribution power lines, as well as substations, leading to prolonged power outages. In contrast, customers in Arizona, South Dakota, North Dakota, and Massachusetts experienced less than two hours of service interruptions on average in 2024.
