Does EIA have information on unplanned outages of U.S. infrastructures?

We provide resources and reports that include information related to unplanned outages or shutdowns of energy infrastructures in the United States:

• The Electric Power Monthly (EPM) includes information in Table B1 and Table B2 on major disturbances and unusual occurrences that affect U.S. electricity supply. The February editions contain data for a complete year, and all data for previous years are available in the EPM archives. 
• Status of nuclear outages provide the operating status of nuclear power reactors daily. 
• The Refinery Capacity Report shows new, shutdown, and reactivated refineries in Table 11.

We also publish data on three metrics of annual electricity service reliability in the United States related to non-momentary electricity service interruptions experienced by customers:

• System Average Interruption Frequency Index (SAIFI), which is the number of service interruptions the average customer experienced.
• System Average Interruption Duration Index (SAIDI), which is the number of minutes of interruptions the average customer experienced.
• Customer Average Interruption Duration Index (CAIDI), which is the average number of minutes it takes to restore service from electricity service interruptions.

We publish utility-level data in the Reliability data file of Form EIA-861. The data are aggregated on the national and state levels in Table 11 of the Electric Power Annual.

In addition, we publish articles on disruptions and outages of U.S. energy supply on our website.
