Feeder Network Performance To measure the reliability performance of PWC feeders, the key indicators are: SAIDI, which indicates the average duration of network and generation-related outages experienced by a customer; and which indicates the average number of network and generation-related outages experienced by a customer. PWC met the feeder network standard in all four feeder categories. However, there has been some deterioration in the performance of long rural feeders and a deterioration in all categories when the system black event of 12 March 2014 is excluded.
