(2) The customer average interruption duration index, representing the average interruption duration or average time to restore service per interrupted customer;

(3) Customers experiencing multiple interruptions, which identifies customers experiencing at least five interruptions annually divided by the total number of customers served;

(4) Customers experiencing long interruption durations, which identifies customers that experienced outages of one or more hours in duration divided by the total number of customers served;
