❓ Hon Giz Watson asks about the methodology used by Western Power to assess the impact of daylight saving on energy consumption. Hon Peter Collier responds that actual measurements were used in conjunction with the Metrix load forecasting package, which accounts for variables like temperature and economic growth.

daylight saving — energy, water and physical activity audits
I refer to the answer to question without notice 396 regarding the energy consumption trends during the three summer daylight saving trial periods. After studying the information on the Western Power website, as referred to by the minister, I seek further information on how Western Power obtained its results. (1) Were the results based on actual measurements, modelling, or a combination of the two? (2) If any modelling was involved, what was its purpose? Hon PETER COLLIER

I thank the member for some notice of this question. Before I respond to the honourable member, the results show that there has been only a virtually negligible or marginal impact on electricity use as a result of daylight saving. (1) The results were based on actual measurements and by comparing these with the Metrix load forecasting package used by Western Power’s system management. (2) Energy consumption is affected by a number of variables, and the modelling package used enables these variables to be taken into consideration to understand the impact of daylight saving. Variables that need to be taken into account when measuring energy consumption include, but are not limited to, temperature, humidity, economic growth, the day of the week, the time of day and the previous day’s load.
