❓ Hon Paul Llewellyn asks about the impact of daylight saving on energy consumption. Hon Kim Chance responds that while there's been a shift in peak usage, overall consumption is more influenced by weather, new connections, and air conditioning use, making it difficult to isolate the impact of daylight saving.

(1)-(2) What an excellent question! Even though the answer is somewhat lengthy, it is of vital interest to every member of the chamber. Western Power constantly monitors energy consumption levels. Since daylight saving was introduced, data has shown that the occurrence of the daily afternoon peak has moved by approximately half an hour, and there has been a very small, early morning increase as early risers turn on the lighting. These changes to the shape of the energy consumption curve do not directly relate to an increase in energy consumption levels as a result of daylight saving. Energy consumption levels are significantly influenced by the number of very hot days experienced in the summer, the number of days with high humidity levels, the frequency of strong afternoon sea breezes and the number of new connections made to the network. The 2006-07 summer had more hot-weather days than the previous year, which was considered a mild summer. Western Power connected approximately 30 000 new businesses and residential properties to the network in 2006, and that inevitably caused an increase in the energy consumption levels compared with those of the previous year. In addition, the number of airconditioning units - which are high energy use applications - installed in Western Australia has grown from 45 per cent in 1999 to more than 71 per cent in 2006. Obviously, that is because of the greater wealth our government has brought to the state. Several members interjected. The PRESIDENT : Order! This is question time, not cause for debate, though it may be afterwards. Hon KIM CHANCE : Although a new peak in energy consumption was recorded during February 2007, it is more likely to have been as a result of the influence of the number of sequential days over 40 degrees and the number of new properties drawing power, rather than the influence of daylight saving. New energy consumption records are usually set each summer for those reasons. For the reasons described, it is not possible to provide a definitive figure on the impact of daylight saving, although it is considered likely to have caused a minor increase in consumption levels in the early morning.
