12 II.6.Energy Information Administration (EIA) Form 861 Data Form EIA-861 collects annual information on electric power industry participants involved in the generation, transmission, distribution, and sale of electric energy in the United States and its territories. In 2014, EIA began publishing reliability statistics in Form EIA-861; therefore, APPA included these statistics in this report for informational purposes. Please note that the following data includes 176 investor-owned, 572 rural cooperative, and 437 public power utilities that were large enough to be required to fill out the full EIA-861 form, and does not include utilities that completed the EIA 861-S form (for smaller entities). Note that the 437 participating public power utilities include entities classified by EIA as municipal, political subdivision, and state. In addition, since the collection and release of EIA form data lags by a year, the data provided here is based on 2019 data that was published October 6, 2020. Therefore, we suggest you only use the aggregate statistics contained herein as an informational tool for further comparison of reliability statistics. In Table 12 and Table 13, an entity calculates SAIDI, SAIFI, and determines major eventME days in accordance with the IEEE 1366-2003 or IEEE 1366-2012 standard. Although EIA collected other reliability-related data, the tables below only include SAIDI and SAIFI data.
