The Minister for Energy has provided the following response: (1) Western Power records all power interruptions, whether they affect two houses, or two thousand, or last just a few seconds or several hours. (a) There were 411 outages in the metropolitan area between 21 February and 6 March 2007, affecting between five and 1400 customers. The average number of customer affected was 357. On average, each customer in the metropolitan area experienced 0.2 outages. (b) There were 331 outages in non-metropolitan areas for the time period, affecting between two and 589 customers. The average number of customers affected was 186. Each customer in non-metropolitan areas of the SWIS experienced, on average, 0.34 outages. (2) Electricity is supplied via a network of feeders, which are not suburb-specific. [See tabled paper no. and ] for lists of metropolitan and non metropolitan suburbs affected by outages to some extent or another. It is important to note that this does not mean the whole suburb was affected. (3) Outages result from numerous causes. Common causes of outages for the time period were: · Lightning; · Pole top fires; · Blown fuses; · Car accidents · Broken conductors; · Unknown Causes; and · Vandalism (4) Supplies to · 62 per cent of customers were restored within 1 hour; · 74 per cent of customers were restored within 1.5 hours; and · 81 per cent of customers were restored within 2 hours. (5) Yes. (6) Several suburbs were affected by more than one outage. However, this is not to say that the same customers or areas within that suburb were affected more than once. Suburbs where more than one outage occurred during the time period are listed [See tabled paper no. ]. (7) Blown fuses can occur because of high loads during heatwave conditions. A blown fuse causes a very localised outage. There were no rolling blackouts because of the heatwave conditions. (8) No. At no time was there any threat of the entire system being blacked out. (9) The peak load reached during the period was 3576 Megawatts (generated). (10) The maximum load for the system is about 3800 Megawatts, allowing for the loss of the largest unit and maintaining reserve margins.
