SYSTEM AVERAGE INTERRUPTION INDEX

FALL RIVER'S RELIABILITY INDEX

Fall River's Operations department tracks the number of minutes each month that members experience a power outage for any reason. Interruptions beyond the control of Fall River Electric can include a power disruption from our wholesale power supplier, a major weather event, an outage caused by animal contact or human causes such as an underground dig up or traffic accidents that impact power poles or substations. This data is collected and reported via the Co-op's System Average Interruption Duration Index (SAIDI) and then compared to other electric utilities in Idaho. 

The average total number of minutes of power interruption over the last five years (2018-2022) averages less than 300 minutes per member. Given that there are 525,600 minutes in a year, Fall River Electric's average is slightly more than just 24 minutes per month. 

Fall River Electric's SAIDI numbers are compared to all the other electric utilities in Idaho. In 2022, Fall River's average number of minutes per member was 165 while the average for all electric utilities in Idaho was more than 500 minutes.
