I thank Hon Barry House for some notice of this question. The answer is quite lengthy, so I table the answer and seek leave to have it incorporated into Hansard . Leave granted. [See paper 3779.] The following material was incorporated — I thank the Hon. Member for some notice of this question. (1) The following sustained power interruptions have occurred in East Augusta over the past 12 months to 26 February 2008. Date Duration Cause 27/02/07 4.7 hours Lightning 09/03/07 4.4 hours Unknown 16/03/07 2.6 hours Bird 28/05/07 2.6 hours Equipment failure 10/06/07 2 hours Equipment failure 11/06/07 1.7 hours Equipment failure 01/07/07 23 hours Wind/wind-borne debris 02/07/07 4.3 hours Wind/wind-borne debris 02/11/07 1.2 hours Equipment failure 21/01/08 1.6 hours Unknown 24/01/08 1.4 hours Unknown 30/01/08 3.1 hours Planned Outage for maintenance work 31/01/08 3.1 hours Vegetation 03/02/08 1.5 hours Equipment failure 06/02/08 1.1 hours Emergency shutdown for hazard 08/02/08 1 hour Emergency shutdown for hazard 21/02/08 2.1 hours Unknown 26/02/08 1 hour Bird Note: This list does not include momentary interruptions (less than five seconds). 2) According to its records, Western Power has received one complaint about power reliability from East Augusta, via the office of the Minister for Energy. There have been two complaints about reliability from Augusta as a whole. 3) East Augusta is supplied via a long rural feeder, known as the Beenup Feeder. This feeder comprises 780 kilometres of lines, 95 per cent of which are overhead. As such it will always be more exposed to faults than urban feeders, which are much shorter. However, Western Power acknowledges there have been a high number of faults associated with equipment failure, and recent problems with current leakage on insulators. 4) Western Power included the feeder supplying East Augusta in its ’40 Worst Feeder Program’ in 2005/06. 5) A thorough inspection of the whole feeder was carried out and problems or potential problems identified. Of these issues, 94 per cent have been remedied and the remainder are being attended to. As part of a separate program, a number of insulators on the high voltage line supplying East Augusta have been replaced with polymeric insulators. This new type of insulator resists the build up of salt and pollutants, reducing the risk of current leakage, pole top fires and television interference. Insulators on a further 61 poles will be replaced with polymeric insulators as part of a package of work which began on 25 February. This package also includes washing transformers, changing surge arrestors and drop out fuses, checking automatic recloser settings and changing four steel raiser poles.

The following material was incorporated — I thank the Hon. Member for some notice of this question. (1) The following sustained power interruptions have occurred in East Augusta over the past 12 months to 26 February 2008. Date Duration Cause 27/02/07 4.7 hours Lightning 09/03/07 4.4 hours Unknown 16/03/07 2.6 hours Bird 28/05/07 2.6 hours Equipment failure 10/06/07 2 hours Equipment failure 11/06/07 1.7 hours Equipment failure 01/07/07 23 hours Wind/wind-borne debris 02/07/07 4.3 hours Wind/wind-borne debris 02/11/07 1.2 hours Equipment failure 21/01/08 1.6 hours Unknown 24/01/08 1.4 hours Unknown 30/01/08 3.1 hours Planned Outage for maintenance work 31/01/08 3.1 hours Vegetation 03/02/08 1.5 hours Equipment failure 06/02/08 1.1 hours Emergency shutdown for hazard 08/02/08 1 hour Emergency shutdown for hazard 21/02/08 2.1 hours Unknown 26/02/08 1 hour Bird Note: This list does not include momentary interruptions (less than five seconds). 2) According to its records, Western Power has received one complaint about power reliability from East Augusta, via the office of the Minister for Energy. There have been two complaints about reliability from Augusta as a whole. 3) East Augusta is supplied via a long rural feeder, known as the Beenup Feeder. This feeder comprises 780 kilometres of lines, 95 per cent of which are overhead. As such it will always be more exposed to faults than urban feeders, which are much shorter. However, Western Power acknowledges there have been a high number of faults associated with equipment failure, and recent problems with current leakage on insulators. 4) Western Power included the feeder supplying East Augusta in its ’40 Worst Feeder Program’ in 2005/06. 5) A thorough inspection of the whole feeder was carried out and problems or potential problems identified. Of these issues, 94 per cent have been remedied and the remainder are being attended to. As part of a separate program, a number of insulators on the high voltage line supplying East Augusta have been replaced with polymeric insulators. This new type of insulator resists the build up of salt and pollutants, reducing the risk of current leakage, pole top fires and television interference. Insulators on a further 61 poles will be replaced with polymeric insulators as part of a package of work which began on 25 February. This package also includes washing transformers, changing surge arrestors and drop out fuses, checking automatic recloser settings and changing four steel raiser poles.

Leave granted. [See paper 3779.] The following material was incorporated — I thank the Hon. Member for some notice of this question. (1) The following sustained power interruptions have occurred in East Augusta over the past 12 months to 26 February 2008. Date Duration Cause 27/02/07 4.7 hours Lightning 09/03/07 4.4 hours Unknown 16/03/07 2.6 hours Bird 28/05/07 2.6 hours Equipment failure 10/06/07 2 hours Equipment failure 11/06/07 1.7 hours Equipment failure 01/07/07 23 hours Wind/wind-borne debris 02/07/07 4.3 hours Wind/wind-borne debris 02/11/07 1.2 hours Equipment failure 21/01/08 1.6 hours Unknown 24/01/08 1.4 hours Unknown 30/01/08 3.1 hours Planned Outage for maintenance work 31/01/08 3.1 hours Vegetation 03/02/08 1.5 hours Equipment failure 06/02/08 1.1 hours Emergency shutdown for hazard 08/02/08 1 hour Emergency shutdown for hazard 21/02/08 2.1 hours Unknown 26/02/08 1 hour Bird Note: This list does not include momentary interruptions (less than five seconds). 2) According to its records, Western Power has received one complaint about power reliability from East Augusta, via the office of the Minister for Energy. There have been two complaints about reliability from Augusta as a whole. 3) East Augusta is supplied via a long rural feeder, known as the Beenup Feeder. This feeder comprises 780 kilometres of lines, 95 per cent of which are overhead. As such it will always be more exposed to faults than urban feeders, which are much shorter. However, Western Power acknowledges there have been a high number of faults associated with equipment failure, and recent problems with current leakage on insulators. 4) Western Power included the feeder supplying East Augusta in its ’40 Worst Feeder Program’ in 2005/06. 5) A thorough inspection of the whole feeder was carried out and problems or potential problems identified. Of these issues, 94 per cent have been remedied and the remainder are being attended to. As part of a separate program, a number of insulators on the high voltage line supplying East Augusta have been replaced with polymeric insulators. This new type of insulator resists the build up of salt and pollutants, reducing the risk of current leakage, pole top fires and television interference. Insulators on a further 61 poles will be replaced with polymeric insulators as part of a package of work which began on 25 February. This package also includes washing transformers, changing surge arrestors and drop out fuses, checking automatic recloser settings and changing four steel raiser poles.
