I thank the honourable member for some notice of the question. (1) The interruptions were caused by a number of factors, including equipment failure and external forces, such as storms, vegetation and car accidents, impacting the network. Equipment failure contributed to about 50 per cent of interruptions in Hillarys and 30 per cent of interruptions in Sorrento. (2) Western Power has a targeted program to install remote monitoring equipment on these powerlines to provide a fast response for fault restoration. In 2010–11 automated switchgear is being installed at eight sites. The automation devices enable Western Power to isolate faults and automatically reconnect power if the cause of a fault passes. In addition, Western Power has an asset replacement program based on condition, with replacement determined by routine inspections. (3) Western Power is deploying automated switchgear and remote monitoring to enhance its ability to detect, isolate and respond to faults. This will reduce the time to restore power supply after a fault. Western Power is also deploying reclosers on feeders to reduce the number of customers who are affected by a fault. (4) Approximately 63 per cent of homes in both Hillarys and Sorrento have underground power.
