II.6. 2018 Energy Information Administration (EIA) Form 861 Data <br />Form EIA-861 collects information on the status of electric power industry participants involved in the <br />generation, transmission, distribution, and sale of electric energy in the United States, its territories, and <br />Puerto Rico. <br />EIA surveys electric power utilities annually through EIA Form 861 to collect electric industry data and <br />subsequently make that data available to the public. In 2014, EIA began publishing reliability statistics in <br />their survey from utility participants; therefore, the Association included EIA reliability statistics in this <br />report for informational purposes. Please note that the following data includes 174 investor-owned, 553 <br />3 <br />rural cooperative, and 389 public power utilities that were large enough to be required to fill out the full <br />EIA 861, not the EIA 861-S form (for smaller entities). In addition, since the collection and release of <br />EIA form data lags by a year, the data provided here is based on the 2018 data that was published in <br />October 1, 2019. Therefore, it is suggested that the aggregate statistics contained herein be used only <br />as an informational tool for further comparison of reliability statistics. <br />In Table 12 and Table 13, an entity calculates SAIDI, SAIFI, and determines major event days in <br />accordance with the IEEE 1366-2003 or IEEE 1366-2012 standard. <br />http://publicpower.org/reliability. Although EIA collected other reliability-related data, the tables below <br />only include SAIDI and SAIFI data.
