System Reliability

The target numbers for the average duration of power outages or System Average Interruption Duration Index (SAIDI) prior to 2016 and for 2016 to present are 60.00 minutes and 57.22 minutes, respectively. For the System Average Interruption Frequency Index (SAIFI) or the average number of power outages per customer, the target numbers are 0.80 for years prior to 2016, and 0.75 from year 2016 up to the present. The target number for the System Average Transmission Line Performance index (SATLPI) or the 12-month rolling average of the number of transmission line faults per 100 miles is 3.0. View the outages per customer, average length of outages, and system average transmission line performance index per year.
