2013 Energy Information Administration (EIA) Form 861 Data Form EIA-861 collects information on the status of electric power industry participants involved in the generation, transmission, distribution, and sale of electric energy in the United States, its territories, and Puerto Rico. EIA surveys electric power utilities annually through EIA Form 861 to collect electric industry data and subsequently make that data available to the public. In 2014, EIA began requesting reliability statistics in their survey from utility participants; therefore, APPA included EIA reliability statistics in this report for informational purposes. Please note that the following data includes investor-owned, rural cooperative, and public power utilities that were large enough to be required to fill out the full EIA 861, not the EIA 861- S form (for smaller entities). In addition, since the collection and release of EIA form data lags by more than a year, the data provided is based on 2013 data only. Therefore, it is suggested that the aggregate statistics contained herein be used only as an informational tool for further comparison of reliability statistics. In the table, if an entity calculates SAIDI, SAIFI, and determines major event days in accordance with the IEEE 1366-2003 or IEEE 1366-2012 standard, they are included under the "IEEE Method" columns. If the entity calculates these values via another method, they are included under the "Other Method" columns. There were approximately 965 utilities that submitted reliability data to the EIA. Additionally, it looks as though a number of utilities submitted incorrect data, which shows itself most in the average SAIFI numbers. For more general information on reliability metrics you can see APPA's website at http://publicpower.org/reliability. Although EIA collected other reliability related data, the tables below only include SAIDI and SAIFI data.
