A new report from the U.S. Energy Information Administration found in 2018 (the most recent data available), U.S. electric utility power interruptions totaled an average of 5.8 hours per customer. The EIA came to this figure using data from utilities that represent 94% of the nation’s 154 million electric customers reported to the EIA.

“Interruptions in electricity service vary in frequency and duration across the nearly 3,000 electric distribution systems in the United States,” said the report. “Power interruptions are caused by many factors, including weather, vegetation patterns, and utility practices.”
