11.6. Energy Information Administration Form 861 Data <br />Form EIA-861 collects annual information on electric power industry participants <br />involved in the generation, transmission, distribution, and sale of electric energy in the <br />United States and its territories. <br />In 2014, EIA began publishing reliability statistics in Form EIA-861; therefore, APPA <br />included these statistics in this report for informational purposes. Please note that the <br />following data includes 175 investor -owned, 464 rural cooperative, and 323 public <br />power utilities that were large enough to be required to fill out the full EIA-861 form. <br />The statistics do not include data from utilities that complete the EIA 861-5 form, which <br />smaller entities complete. Note that the 323 participating public power utilities include <br />entities classified by EIA as municipal, political subdivision, and state. In addition, since <br />the collection and release of EIA form data lags by a year, the data is based on 2021 <br />data that was published October 6, 2022. Therefore, we suggest you only use the <br />aggregate statistics contained herein as an informational tool for further comparison of <br />reliability statistics. <br />In Form EIA-861, an entity provides SAIDI and SAIFI including and excluding ME days in <br />accordance with the IEEE 1366-2003 or IEEE 1366-2012 standard. <br />Although EIA collected other reliability -related data, the tables below only include SAIDI <br />and SAIFI data including and excluding ME days. You can download the full set of data <br />at: www.eia.gov/electricity/data/eia861/. <br />Table 12.
