Eaton has released its Blackout Tracker Annual Report for 2013. For the fifth year running, California topped the list of states with the most power outages, followed by Texas and Michigan. On average, 6,543 people were affected for more than three hours per outage in 2013 and power failures caused problems for people and businesses in all 50 states.

Blackout Tracker data is based on a full year of reported power outages across the United States and is organized into two sections: an overview of national power outage data and power outage data by state. Overall, 3,236 reported outages were used as the basis for the 2013 report, representing an increase of about 15 percent from the 2,808 outages reported in 2012. The reported number of people affected by outages decreased from 25 million in 2012 to 14 million in 2013. However, complete data is often unavailable on certain aspects of reported outages, including the number of people affected and the duration of the blackout.

Data for the annual report is based on reports from news services, newspapers, websites (including those of newspapers and TV stations) and personal accounts. To download the entire annual report and track power outages across the U.S., please visit
