Abstract: The paper presents a statistical analysis of electricity spot prices in a deregulated market in New South Wales, Australia, in the period 10 May, 1996 – 7 March, 1998. It is unusual that a single set of data, such as this, allows one to consider a relatively systematic sequence of statistical problems, each resulting in clear, although not always obvious, solutions. This is the reason why these data and their analysis can be used as a rel atively good base for training in practical statistical analysis. Existing for merly as a report, the material has been used in lecture courses in several universities in Australia and New Zealand.
