QuestionView source ↗
(1) How many power outages have occurred in the southeast corridor since 1 December 2006?
(2) What is the duration of each power outage?
(3) What was the cause of each power outage?
(4) Given that the Ranford Road feeder is supposed to have the greatest impact on reducing power outages in the southeast corridor, and that its proposed operational date of mid March has passed, when will the feeder become operational?
(5) What other initiatives are being implemented to minimise outages in the southeast corridor?

The Minister for Energy has provided the following response: (1) Western Power has taken the southeast corridor to mean the areas supplied from the Gosnells and Southern River zone substations. This comprises 13 suburbs supplied either in part or all by the Gosnells Substation. These suburbs include Beckenham, Canning Vale, Gosnells, Huntingdale, Kelmscott, Kenwick, Langford, Maddington, Martin, Orange Grove, Southern River, Thornlie and Westfield. Since December 2006, 151 power outages have occurred somewhere on these lines. It is important to note that the number of customers affected by an outage can vary from two customers to several thousand customers. (2) Outages ranged in duration from a few minutes to many hours. The average duration of outages in the southeast corridor for the period specified was 123 minutes. Pole top fires, which often require a pole or crossarm to be replaced, and therefore result in a lengthy outage had a significant impact on the average duration. (3) Causes of the outages included: Birds. Equipment failure. Fire, other than pole top fires. Planned outages while upgrade work is carried out. Pole top fires. Transmission failure. Unknown. Interference with the power line has occurred and a subsequent patrol of the line has failed to find conclusive evidence. The interference is not generally related to equipment failure and can be caused by tree branches or other kinds of interference. Vehicles. Wilful damage. Wind including wind borne debris. (4) The Ranford Road feeder became fully operational19 April 2007. (5) There are a number of maintenance and operational initiatives that are planned: · Minor reconfiguration of part of the network supplied by the Gosnells substation. The reinforcement work is now complete except for the commissioning of four reclosers. The reclosers are installed and ready to be commissioned in the very near future. · Targeted maintenance and inspection for some of the Gosnells feeders; · Targeted replacement of conductors and other equipment on parts of the network; · Pole siliconing to reduce the likelihood of pole top fires; · Installation of automated switching devices on the network to improve outage restoration and minimise customer impact in the event of an outage.
