Average frequency and duration of electric distribution outages vary by states

U.S. Energy Information Administration --------- Interruptions in electricity service vary by frequency and duration across the many electric distribution systems that serve about 145 million customers in the United States. In 2016, customers experienced an average of 1.3 interruptions and went without power for four hours during the year. Although some distribution customers have backup generators that provide auxiliary power, most customers are without electricity when outages occur.The reliability of electricity supply systems is generally measured using two metrics that show the duration and frequency of outages: System Average Interruption Duration Index (SAIDI) and System Average Interruption Frequency Index (SAIFI). Many of the standards in reporting these metrics were initially developed by the Institute of Electrical and Electronics Engineers (IEEE), an international, professional trade association for electrical and computer information technologies, engineering, and related fields.
